Local candidates seeking to personalize their campaigns and build affinity with target voters may highlight particular aspects of their identities within campaign communications. One such aspect they may reference is their class background. For example, campaign materials frequently mention a candidate's occupational or educational background in order to build rapport with the electorate and indicate shared status, interests or values. This article compares the self-presentation of class identity among political candidates in the 2022 Ontario and Québec provincial elections. We code 976 online candidate biographies to assess how class background is referenced and examine the impact of variables such as party affiliation and riding demographics on self-presentation of class status. We further compare campaign biographies with data on candidates’ class backgrounds separately sourced from news reports and social media (LinkedIn). This allows us to determine which elements of class identity candidates choose to highlight, downplay or embellish in their campaign biographies.
Hospital food service quality significantly impacts patient satisfaction with overall care(1) and can influence food intake, thereby increasing the risk of malnutrition(2). By contrast, meals tailored to patients’ needs result in lower complications and hospitalisation costs(3). With Australia’s ageing population and projected increases among racial and ethnic minority migrants, service delivery must adapt to promote equity and inclusion in the healthcare system. However, data is lacking on the lived experience, preferences, and acceptance of hospital food service and meal quality among older patients from culturally and linguistically diverse (CALD) backgrounds. This study aimed to bridge this gap by investigating the differences in hospital food services related to cultural and ethnic backgrounds. Semi-structured qualitative interviews were planned among 15 Australian-born and 15 CALD-background patients, aged 65 years or over, admitted to the Department of General Medicine at Flinders Medical Centre. Patients admitted with a highly contagious infectious disease (e.g., COVID-19), those referred for palliative care, receiving parenteral or enteral nutrition, or on nil-by-mouth orders were excluded. Translators were available to participants upon request. With participants’ consent, all interviews were audio recorded and transcribed verbatim. Transcripts were analysed thematically using Braun and Clarke’s six-phase process(4). Data was inductively coded with a phenomenological perspective to explore participants’ experiences with hospital food services. Similar codes were grouped together and further developed into themes through iterative discussions with the research team. The current analysis involved six participants from each group to present preliminary results. Among the 12 participants, the mean age was 82 years, ranging from 72–92 in the Australian-born group and 68–92 in the CALD group. Five primary themes emerged: (1) No Complaints—participants did not want to complain about their meals, preferring staff to focus on their healthcare. This attitude was compounded for CALD participants who lacked the language to voice complaints; (2) Food and Identity—CALD participants viewed themselves separately from Australian-born patients, with the lack of culturally familiar food contributing to a feeling of being the minority; (3) Acceptance—the food service was viewed in the context of the overall hospital system, with participants accepting that meals may not suit their preference; (4) Experiences of the Food Service—influenced by participant’s individual preferences for meal quality, menu options, and staff interactions; and (5) Nutrition and Health—All participants had a preference for smaller portions due to their perception of reduced nutritional needs, yet meals were also valued for enjoyment. These preliminary results indicate that hospital food services should offer culturally familiar options, improve patient-staff communication, and provide personalised, smaller portions to enhance patient experience. Addressing the enablers and barriers to meeting cultural and individual dietary needs in hospitals will promote equity, diversity, and inclusion in healthcare.
Dietary fat type has been suggested as a risk factor for development of multiple sclerosis (MS)(1); however, the evidence is inconclusive. We aimed to test associations between dietary patterns correlated with intake of saturated fat (SFA), polyunsaturated fat (PUFA), monounsaturated fat (MUFA), along with the Dietary Approaches to Stop Hypertension (DASH) score, and risk of a first clinical diagnosis of central nervous system demyelination (FCD), a common precursor to the diagnosis of MS. We used data from the Ausimmune Study, a multicentre Australian case-control study of people with an FCD, aged 18–59 years. Using dietary intake data from a 101-item food frequency questionnaire(2), dietary patterns characterised by fat type (DP1; DP2) were generated through reduced rank regression with SFA, PUFA and MUFA as response variables. DASH scores were calculated. Logistic regression with full propensity score matching (matched on age, sex, study region, education, smoking history, history of infectious mononucleosis, deseasonalised serum 25-hydroxyvitamin D concentration, total energy intake, dietary misreporting) was used to test associations between dietary patterns (DP1, DP2, DASH) and FCD (cases = 259, controls = 497). Interactions between dietary exposures and sex were explored. DP1 was positively correlated with all fats and was characterised by high positive factor loadings for whole milk, processed red meat, and high-fat cheese, and high negative factor loadings for skimmed milk and fruits. DP2 was negatively correlated with SFA, but positively correlated with PUFA and MUFA, and was characterised by high positive factor loadings for margarine, nuts, and wholemeal bread, and high negative factor loadings for butter, whole milk, and sugar, preserves and confectionary. There were no associations between DP1, DP2 or DASH with FCD. These dietary patterns, characterised by fat type, showed no association with risk of FCD. To generate robust evidence on the role of dietary fat in MS onset, dietary patterns characterised by fat type could be explored in other population groups.
The aim of this study was to investigate sensorimotor functions that require cerebellar processing, and visuospatial perception and visuospatial abilities in adult patients with attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD).
Method:
We included patients with unmedicated ADHD (n = 52), medicated ADHD (n = 39), ASD (n = 33), the combination of unmedicated ADHD and ASD (n = 31) and controls (n = 78). A multimodal set of neurocognitive tests and motor tasks were administrated to evaluate cognitive and motor skills.
Results:
All patient groups exhibited significantly worse performances than controls in sensorimotor functions, visuospatial perception, and visuospatial abilities. We observed significant associations between sensorimotor functions and visuospatial perception and visuospatial abilities. We conducted a regression analysis to evaluate the impact of potential confounders on neurocognitive outcomes. The results indicated that age, level of education, and insomnia, but not anxiety or depression, affected the performance on some tests.
Conclusions:
Our results reveal deficits in sensorimotor functions, visuospatial perception, and visuospatial abilities in patients with neuropsychiatric disorders. Clear deficits emerged, despite the majority of patients showing a mild degree of severity index of ADHD/ASD across all groups (61–84%). The results are consistent with the idea that these disorders are linked to cerebellar deficits. Our results suggest that these objective tests have the potential to enhance clinical evaluations.
Childhood obesity persists at historically high rates globally, including an increasing number of children with severe obesity(1–3). Despite the growing demand of families with children needing treatment, effective interventions are largely unavailable or inaccessible(4,5). Using technology to transform such services that are conventionally delivered in person and offering electronic health (e-Health) interventions, may address limitations of current childhood obesity treatment. A randomised control trial (RCT) with a waitlisted control group evaluated the effectiveness of a 10-week family-focused web-based healthy lifestyle program with health coaching sessions, for treating childhood overweight and obesity, over 10 weeks. Outcome measures included change in children’s body mass index (BMI) z-score, waist circumference, dietary intake, physical activity, and quality of life, collected online at baseline and end of the web-based program (10 weeks). A total of 148 children (125 families) aged 7–13 years, with BMI ≥ 85th percentile, living in Victoria, Australia, were recruited and randomised to intervention (Cohort 1) or waitlist control (Cohort 2), of which 102 children (85 families) completed the RCT. Cohort 2 received no intervention during the control period. A clinically meaningful decrease in BMI z-score, in the context of weight maintenance and height growth, was observed in Cohort 1 compared to a negligible change found in Cohort 2 (mean difference in change in BMI z-score Cohort 1 vs Cohort 2 = −0.1; 95% confidence interval, −0.2, –0.0). Compared with Cohort 2, Cohort 1 adopted health-supporting lifestyle behaviours, such as improved diet quality and increased physical activity; and reported a clinically significant improvement in children’s quality of life at 10 weeks. Cohort 2 demonstrated similar changes in outcome measures after receiving the web-based program. Findings from this study furthers the growing body of evidence on the potential of e-Health interventions to upscale childhood obesity treatment. E-Health interventions, including a low-intensity program that requires minimal contact time with health professionals online, can enhance the effectiveness of conventional treatment services.
Irritable bowel syndrome (IBS) is a chronic disorder of gut-brain interaction that affects 3.5% of Australians and is characterised by abdominal pain and altered bowel motions(1). People with IBS have described low treatment satisfaction from healthcare providers and services, citing a lack of person-centred care(2). This is concerning given that the dietary management of IBS using the low fermentable oligosaccharide, disaccharide, monosaccharide and polyol (FODMAP) diet (LFD) is the most efficacious dietary treatment for global symptom improvement(3). This study aimed to explore people with IBS’s experiences of a dietetic-mediated LFD and identify strategies for optimising LFD implementation. A qualitative descriptive study design involved semi-structured interviews with adults with IBS who participated in a dietetic-led research study on predictors of response to the LFD. Participants who commenced at least one of the three LFD phases between October 2020 and April 2022 were invited to participate. An inductive, iterative process was used to code participant transcripts and confirm the final themes. Themes were mapped against the Theoretical Domains Framework (TDF) and Behaviour Change Wheel (BCW) to inform interventions to optimise the delivery of the LFD. Seventeen adults (32%, 17/53 response rate) aged 39 ± 15 years and 88% female-identifying consented to interviews. All phases of the LFD were completed by n = 9, with n = 4 completing Phases 1 and 2, n = 1 completing Phase 1 only and n = 3 commencing but not completing the first phase. Two main themes emerged. Firstly, patients wanted more dietetic appointments and support to implement the LFD. Participants wanted more frequent dietetic contact (approximately halfway through Phase 1, early to mid-Phase 2 and three to six months after commencing Phase 3) and appointments that were tailored to their individual needs and circumstances (face-to-face, phone and/or email) in each phase to troubleshoot diet implementation and manage symptoms. Further, more detailed education materials were requested, including recipes, acceptable foods, including commercial foods, and meal plans. Secondly, participants wanted a person-centred, multidisciplinary care approach with health professionals working together to be considered, given the complexity of IBS, especially with incomplete symptom resolution with the LFD. Participants recognised that stress, general anxiety and lifestyle factors contributed to symptoms and further support beyond the LFD was required. When mapped to the TDF and BCW, it was evident that environmental context and resources, knowledge, skills, beliefs and capabilities of the TDF and restructuring of the environment, education, training and self-monitoring domains of the BCW overlapped. The findings emphasise the need for a more person-centred care model using varied modes of delivery designed to suit individual needs and behaviour change requirements. Implementing multidisciplinary care, alongside behaviour change techniques, may assist treatment completion and IBS management.
Discretionary foods that are energy-dense and nutrient-poor contribute to over one third of total energy intake in Australian children and adults, and the typical portion sizes of many discretionary foods have increased significantly in the last two decades(1). The portion size norms (described as a typical perception of how much of a given food people choose to eat at a single eating occasion) are likely to have increased concurrently, with larger sizes now being considered the new normal(2). Public health interventions are urgently needed to reduce the portion size norms and consumption of discretionary foods(3), but the acceptability of such interventions remains unknown. Therefore, this qualitative study aimed to gain insights into consumers’ attitudes towards potential interventions targeted at promoting portion control of discretionary foods. Four online focus group sessions were conducted via Zoom with healthy Australian adults who regularly consume discretionary foods. A question guide was developed to gather participants’ perspectives around four potential public health interventions; reduction of the default serving sizes, increasing serving size options, changes to package sizes, and improving serving size labelling. A female facilitator moderated all focus groups, with a second moderator present to capture other relevant details. Collected data were analysed using a hybrid approach combining deductive and inductive thematic analyses. A total of 35 participants completed the study (19 females, mean age 38 ± 14 years). Participants identified the current food environment as promoting overconsumption; larger serving sizes were reported to be more ubiquitous and better value for money than smaller size options. An overall positive attitude towards the proposed interventions was noted. Out of the four proposed interventions, participants considered the most acceptable intervention to be providing a wider range of serving size options while maintaining a consistent unit price. Other acceptable interventions included reducing the default serving sizes with concurrent price reduction; education and clear guidance around portion size selection (for example, the involvement of health professionals to promote portion control, along with relevant recommendations of appropriate portion sizes from health authorities); more practical on-pack serving size suggestions; and innovative package designs that enable better portion control without contributing to food and plastic waste. In conclusion, participants identified a need for and were in support of interventions aimed at the portion control of discretionary foods. Further research should focus on examining the feasibility and effectiveness of the potential interventions to reduce the purchasing and consumption of large serving sizes. More efforts from public health authorities are required to develop practical and tailored recommendations for consumers around appropriate portion sizes for discretionary foods. Collaboration with the food industry and policy makers is also necessary for implementing public health interventions to reduce the excessive intake of discretionary foods.
The various COVID-19 lockdowns and restriction periods significantly changed both food accessibility and availability, which considerably impacted food practices of Australians. Food insecurity prevalence increased in Tasmania(1), but data from elsewhere in Australia is scarce and other changes in food shopping habits have not been reported. We aimed to explore Australian adults’ self-reported experiences of running out of food, spending on food and food shopping habits during the COVID-19 restriction periods in 2020. An online survey of Australian adults was administered via Qualtrics. Chi-square tests examined bivariate associations between categorical variables (gender, age, change in employment status, education level, main language spoken at home and marital status), and responses to the main research questions. Respondents (n = 764) were predominantly female (86%), primarily from Victoria (48%), with the majority over 55 years of age (57%, mean age [SD] 53.4 [18.1] years). Additionally, half (51%) were not in paid employment. Overall, 11% reported running out of food and not being able to purchase more. There was an association between age and running out of food (4% of the 64–74 and 75+ year old age groups ran out of food compared to 23% of the 18–24 year olds, p < 0.001, chi square). The most reported reasons for running out of food, out of six provided options, were ‘lack of availability in the shops’ (74%) and ‘lack of money’ (34%). There was no association with gender, employment status change, education level, main language spoken at home, or marital status and running out of food. When asked how the amount of money spent on food changed during COVID-19, most respondents (n = 318, 42%) reported spending about the same amount of money as before the pandemic, 284 (37%) reported spending more and 162 (21%) reported spending less on food. About a third of respondents (38%, n = 293) reported buying more food than they needed since the start of COVID-19 and 9% (n = 66) reported wasting more food than usual. This did not differ with age, gender, employment status change, education level, main language spoken at home, or marital status. Nearly two-thirds (63%) reported that they had changed how they bought their food since the start of COVID-19.Of these 75% reported a change in frequency of food shopping and 45% reported a change in the amount of time spent food shopping. Just under half (44%) reported a change in the amount of money spent on food and 42% reported a change in the food bought. The COVID-19 pandemic restrictions caused significant changes to Australians’ food procurement and younger people appeared more at risk of food insecurity. Policies that support young people are important to ensure food security in the most vulnerable groups.
Handgrip strength (HGS) is a marker of protein-energy status in people on haemodialysis (HD). Best practice guidelines recommend measuring HGS before the commencement of the dialysis session, which is not always possible(1). No previous research has compared the reliability, reproducibility and agreement of HGS values pre- and mid-dialysis. Here we aimed to determine the reliability, reproducibility and agreement of HGS values pre- and mid-dialysis. Participants were recruited from four HD units (n = 47). Eligible participants were stable on HD for at least 3 months and not acutely unwell. HGS was measured in triplicate on the non-fistula arm before dialysis (pre-dialysis HGS) and two hours into dialysis (mid-dialysis HGS) for three consecutive weeks. Wilcoxon signed ranked tests were used to determine the difference between pre and mid-HGS. Friedman tests with Dunn’s post hoc test were used to determine the repeatability of the HGS measures over three weeks. Bland Altman plots were used to determine the agreement between pre- and mid-measures. We observed that HGS measures taken pre- and mid-dialysis differed statistically (19.0 kg [IQR, 14.5–28.1] vs 19.9 kg [IQR, 15.0–28.4], p = 0.005), but not to a clinically relevant level(2,3). There were no significant differences in pre-dialysis HGS measures (p = 0.34) nor mid-dialysis HGS measures (p = 0.16) over the 3 weeks. Bland Altman plots indicated agreement between pre- and mid-dialysis HGS measures, suggesting no systematic bias in HGS. This study found that HGS taken at either pre- or mid-dialysis were reliable and reproducible. These data indicate reasonable agreement between pre- and mid-dialysis HGS measures. Mid-dialysis HGS is a valuable tool for monitoring changes in the nutritional status of HD patients, providing HGS is consistently measured mid-dialysis.
Children attending Early Childhood Education and Care settings (ECEC) receive half of their daily nutritional needs from these services(1,2). Issues such as poor menu quality and high food waste in ECEC have been documented(3), which has implications for human and planetary health. Thus, monitoring food served and wasted in ECEC is crucial. Weighed measures are most rigorous, but reliable weighing protocols are needed to support accuracy(4). A self-administered audit tool for ECEC cooks was developed to measure the weight of food served (for nutritional analysis) and food wasted at pre-consumer (serving waste) and post-consumer (plate waste) levels. This tool was used in previous ECEC research(3) and offers a low cost, scalable option for monitoring diet quality and food waste. The aim of the present study was to assess the equivalence of the audit tool across administrators. Data was collected in June 2024 at a university food laboratory by a trained researcher (TR) and six research assistants (RAs) using the same protocol, and under conditions similar to those in ECEC settings. Menu and waste data from previous ECEC research(3) were used to simulate provision and waste of one meal and two snacks for 25 children over two days. Raw ingredients, simulated serving waste and plate waste were weighed and photographed first by the TR, followed by RAs. Weighing was conducted individually, and data entry sheets coded to ensure blinding of data among researchers. Coded data were entered into an Excel spreadsheet, with accuracy checks. The mean % difference and standard deviation of difference between TR and RAs for weights of raw ingredients, total food served, serving waste and plate waste were calculated. Equivalence testing was used to verify if the mean % (and 90% CI) were within established margins (± 10%). Results showed high reliability of the tool between users, with statistical equivalence for weight comparisons of total prepared food served, total serving waste and total plate waste (all p’s < 0.001). For raw ingredients most items (45 of 54) were statistically equivalent (all p’s < 0.05). Results were inconclusive for prepackaged items, grated apple and sweet chilli sauce (n = 5) and not equivalent for some small items (oil and garlic, n = 4). The audit tool could therefore be considered reliable for measuring total food served, serving waste, and plate waste, and provided accurate measurements for most individual raw ingredients. The tool provides a scalable, low-cost option to audit food provision and waste in ECEC settings. Its self-measurement enables research in geographically diverse ECEC settings. It also has the potential of becoming a support strategy for ECEC to monitor and improve their own food provision and waste levels. Future research could focus on digitalisation of the tool.
Hospital-acquired pneumonia (HAP) represents one of the most common nosocomial infections in intensive care units (ICUs), accounting for 25% of all hospital-acquired infections. While oral care is recommended as a preventive measure, the relationship between standardized oral care practices and HAP incidence remains incompletely characterized.
Objective:
To evaluate the association between oral care practice compliance and HAP incidence in ICU patients, and to identify specific aspects of oral care delivery that influence outcomes.
Methods:
We conducted a prospective mixed-methods observational cohort study from May 2021 across seven ICUs in a tertiary hospital in China. The study utilized a two-phase approach: (1) systematic assessment of oral care implementation through structured observation of nursing staff (n = 58), and (2) prospective evaluation of HAP outcomes in patients (n = 142). Primary outcomes included oral care compliance metrics and HAP incidence. HAP was defined according to standardized clinical criteria and confirmed by two independent physicians.
Results:
Among 142 unique patients, 63 (44.37%) received oral care orders. The oral care completion rate was 61.93%, and the qualification rate was 54.13%. In our analysis, HAP (including both ventilator-associated pneumonia [VAP] and non-ventilator hospital-acquired pneumonia [NVHAP]) occurred in 15/63 (23.81%) patients receiving oral care and 22/79 (27.85%) patients without oral care. Multivariate analysis revealed that incomplete oral care (adjusted OR 2.47, [95% CI, 1.15–4.45], P = 0.009), non-qualified care techniques (adjusted OR 3.17, [95% CI, 1.45–6.35], P = 0.002), and inadequate item qualification (adjusted OR 3.33, [95% CI, 1.47–6.55], P = 0.001) were independently associated with increased HAP risk, after adjusting for confounders. Stratified analysis showed similar associations in both VAP and NVHAP subgroups.
Conclusion:
Our investigation demonstrated that suboptimal oral care practices were associated with increased HAP risk in ICU patients. Implementation of evidence-based standardized protocols and improved adherence strategies may help reduce HAP incidence.
Chinese immigrants living in Western countries are at a higher risk of developing chronic diseases compared to those in China, due to the development of unhealthy dietary patterns during the process of acculturation(1). Australia, with 2.3% of its population being Chinese-born(2), serves as a representative country to explore Chinese immigrants’ food choice determinants. Food choice determinants have been widely researched, with numerous factors identified such as affordability, taste preferences and hunger/satiety. Contento (2018) developed a comprehensive framework which identified and categorised over 30 determinants into four socio-ecological groups(3). Therefore, the focus of current research is not the identification of food choice determinants but to explore the interactions among these determinants. Understanding the cultural influence on food choice is vital for target groups with a shared ethnic background. This study aimed to qualitatively explore the similarities and differences in food choice determinants between Chinese people in mainland China and those living in Australia. Ethical approval for this study was obtained from Monash University Human Research Ethics Committee. Eighteen participants were recruited for semi structured in-depth interviews from June 2021 to March 2022, with eight from Australia and ten from mainland China. Convenience and snowball sampling methods were employed to ensure a diverse sample regarding socio-economic background, occupation, health status, age, and education level. Interviews were conducted in Mandarin via in-person or video/voice calls and were audio-recorded and transcribed verbatim. Thematic analysis and investigator triangulation were used for data analysis. Four themes were identified. (a) Food choice determinants were influenced by nutrition perceptions and personal food philosophy. Chinese Australian immigrants were influenced by Western nutrition beliefs to a greater extent than their counterparts living in mainland China. Non-scientific or controversial nutrition beliefs were common. Personal food philosophy (e.g., eating food is for survival only, or for enjoyment, or for health) profoundly influences food choices. (b) Chinese people adjusted their dietary habits in response to clinical symptoms or self-observed physiological changes, such as, gaining weight or digestive issues. (c) Convenience was a predominant food choice determinant due to factors like long working hours, lack of motivation to cook, lack of cooking skills, time restrictions, and viewing cooking as a chore. (d) Different food environments in China and Australia lead to distinctive food choices. Chinese Australians were more price-sensitive, had more food safety concerns, and cooked more frequently at home than mainland Chinese, due to differences in food affordability, accessibility and information exposure between these two countries. Importantly, nostalgia for childhood foods had a unique influence on certain food choice behaviours in Chinese Australians. These cultural characteristics in food choice determinants should be considered by health educators, nutrition professionals, and policymakers when developing culturally appropriate health interventions for Chinese people.
Flavonoids, found in plant foods, are becoming increasingly recognised for their health benefits(1). A valid, reliable and short dietary assessment tool is necessary to assess flavonoid intake, as current methods are burdensome for researchers and participants. This study aimed to evaluate the validity and reproducibility of a flavonoid food frequency questionnaire (Flav-Q), which was derived from the Kent & Charlton Flavonoid Food Frequency Questionnaire (FFQ)(2). The Flav-Q contains 23 items and was validated against repeated 24-hour dietary recalls in an Australian adult population (18y+). The Flav-Q was administered at four time-points over 12 months period (n = 80). At each time-point, two 24-hour dietary recall surveys were completed using Intake-24(3). Usual flavonoid intake was assessed by cross-referencing food lists with the Phenol-Explorer database and averaged using the multiple source method (MSM) for participants who had at least 4 recalls. The criterion validity of the Flav-Q at baseline was compared against the usual intake using the Wilcoxon signed-rank test, Spearman’s correlation coefficient, Bland-Altman plots, and Cohen’s kappa (κ)(4). The reproducibility of the baseline Flav-Q (Flav_Q1) was compared with time points 2, 3, and 4. Mean total flavonoid intake was higher for Flav-Q1 compared to usual intake (443.2 mg/day vs 234.4 mg/day, p < 0.001) and overestimated subclass intake except for flavanones. Moderate to strong correlations were found between Flav-Q1 and usual intake for total flavonoids (r = 0.66, p < 0.001; κ = 0.45, p < 0.001) and subclasses flavan-3-ols (r = 0.72, p < 0.001; κ = 0.53; p < 0.001)), flavonols (r = 0.55, p < 0.001; κ = 0.40, p < 0.001), flavanones (r = 0.49, p < 0.001; κ = 0.30, p = 0.007), and a weaker non-significant correlation for anthocyanin (r = 0.38, p < 0.001; κ = 0.15, p = 0.18) and flavones (r = 0.34, p < 0.001; κ = 20, p = 0.07). Bland-Altman plots showed a large bias and wide limits of agreement (61.64%) for total flavonoid intake. Flav-Q demonstrated high reproducibility across all timepoints (Flav-Q1 vs Flav-Q2 r = 0.82, p < 0.001; κ = 0.70, p < 0.001), Flav-Q1 vs Flav-Q3 (r = 0.68, p < 0.001; κ = 0.47, p < 0.001), Flav-Q1 vs Flav-Q4 (r = 0.63, p < 0.001; κ = 0.47, p < 0.001). Mean percentage differences between repeated timepoints for total flavonoid ranged from 19% to 31%, with Bland-Altman plots showing good levels of agreement. Overall, the Flav-Q tool was reproducible and demonstrated some agreement for assessing the intake of total flavonoid and its subclasses. However, further validation to determine reasons for over-estimation is necessary.
An infinite sequence $\alpha $ over an alphabet $\Sigma $ is $\mu $-distributed with respect to a probability map $\mu $ if, for every finite string w, the limiting frequency of w in $\alpha $ exists and equals $\mu (w)$. We prove the following result for any finite or countably infinite alphabet $\Sigma $: every finite-state selector over $\Sigma $ selects a $\mu $-distributed sequence from every $\mu $-distributed sequence if and only if$\mu $ is induced by a Bernoulli distribution on $\Sigma $, that is, a probability distribution on the alphabet extended to words by taking the product. The primary—and remarkable—consequence of our main result is a complete characterization of the set of probability maps, on finite and infinite alphabets, for which finite-state selection preserves $\mu $-distributedness. As a consequence, the shift-invariant measures $\mu $ on $\Sigma ^{\omega }$, such that any finite-state selector preserves the property of genericity for $\mu $, are exactly the positive Bernoulli measures.
Traditional Cambodian recipes have been prepared the same way over time, with their nutritional quality largely unknown. Poor nutritional status is common among Cambodian children with 22% experiencing stunting and 16% underweight(1), while Cambodian women exhibit the double burden of malnutrition with 44% having anaemia and 33% above the healthy weight range(1). Most Cambodian women have inadequate intakes of key nutrients including vitamin A, thiamine, zinc and iron(2). Recent Cambodian studies have focused on increasing nutrient intakes, with improved nutritional quality of mixed dish recipes a novel, potential approach(3). However, the absence of a Cambodian-specific food composition database means nutrient information for common mixed dishes is unavailable. This study aimed to quantify the nutrient profile of traditional mixed dishes commonly consumed by Cambodian women and children. A secondary aim was to qualitatively explore Cambodian women’s receptiveness to nutrient-enhanced traditional mixed dishes. A sequential mixed methods approach was used to collect traditional recipes and nutritionally analyse Khmer mixed dishes, then conduct qualitative focus groups to assess recipe acceptability. Over 900 recipes were collected by Cambodian women who had a child < 5 years via a custom-built smartphone app, as part of a dietary assessment study in Cambodia in 2019 and 2020. After grouping and counting recipes to determine consumption frequency, ingredients and quantities, these were consolidated into 27 commonly consumed recipes. The nutrient composition of consolidated recipes was determined using an INFOODS template(4). Dietitians then created six nutritionally-enhanced versions of Khmer mixed dishes by switching or adding common high-nutritive ingredients. In Siem Reap province four 90-minute focus groups were conducted with Cambodian mothers (two rural, two urban). Three dishes per group were prepared and served with rice, and women’s responses to each nutritionally-enhanced Khmer mixed dish were discussed. Nutrient analysis indicated that a median serve of traditional Khmer fish soup contributed 25% protein, < 10% iron and folate, and < 20% zinc and thiamine required daily for non-lactating women. Initially Cambodian women were sceptical about modifying traditional Khmer recipes, expressing resistance to change: ‘They would wonder, where did you learn that?’. Inspecting each dish, they discussed how strange the ingredients seemed, disbelieving their acceptability: ‘It is weird […], never put other green leaves’. After tasting, women expressed surprise they liked the flavour, describing these modified dishes as ‘unique’ or ‘creative’, recognising they would ‘gain more nutrition’ with this enhanced recipe. Most women declared they would try this modified dish at home ‘I would like to share it to my sister and my friends and family’. Results highlight future interventions promoting nutritionally-enhanced recipes of commonly consumed meals need to support women to overcome initial resistance through trialling them to evaluate acceptability, prompting them to share with their household.
Food security is a crucial issue for policymakers, practitioners, and researchers(1). Network analysis, which examines complex systems and relationships(2), can provide valuable insights into food security through the interactions of individuals and organisations. This study aimed to explore the Twitter network discussing food security in Australia, focusing on user connections and key influencers. Data was collected from 2019 to 2021 using the Twitter API and Python software(3). Eligible tweets were those sent by Australian users, in English, and containing at least one food security-related search term. From this data the interactions (re-tweets, replies and quote tweets) between users was extracted, including only users who interacted with another user from the dataset at least twice. Social network analysis was conducted using the software Gephi(4) where interactions (edges represented as lines) between users (nodes represented as circles) were visualised. Sentiment and topic analysis of the tweets were also used to explore what was being said and in what tone(3). The network comprised n = 2,172 Twitter users and 3,304 connections. However, 394 connections (11.9%) were self-interactions, contributing to a low network density of 0.001. The median number of users each user connected with (degree) was 1 (25th, 75th percentiles 1, 2), ranging from 1 to 346. The most common topic discussed by n = 589 users (27.1%) was global food production and the most common sentiment was positive (n = 1,228 users, 56.5%). High modularity (0.740/1) indicated the network could be divided into distinct communities that had dense connections within but not necessarily outside of their community. There were 353 communities, with 209 (59.2%) of these communities containing only one user. The largest ten communities represented 71.9% of the network, with the largest community (n = 530 users) focusing on Australian food insecurity and food banks, discussed from a political and refugee perspective with a generally negative tone. Betweenness centrality identified key influencers who connected various parts of the network. The top 20 influential users included seven non-profit organisations, seven academics, three advocacy groups, two political accounts, and one government account. Non-profit organisations often interacted with each other, while academics were mainly clustered in the same community. High-degree users, who had the most direct connections (≥ 35 connections), were predominantly non-profit organisations, with fewer academic and more political accounts than those with high betweenness centrality (≥ 12,000). Despite the overall low network density due to isolated users and relatively insular communities, some individuals exhibited extensive connections, highlighting their central role and potential influence in Twitter discussions. Future research could examine how these dynamics evolve and explore strategies to enhance connections, thereby enabling diverse social media users to better influence public discourse and ultimately policy on food security issues.
Nutrition professionals are needed to be change agents for promoting healthy and sustainable food systems, however, the best methods for preparing students are unclear(1,2). Experiential learning opportunities, such as hands-on activities with sustainable food systems, could bridge the gap between theoretical knowledge and practical application(3). This study aimed to evaluate how an experiential learning activity using Farmwall Vertical Garden, an aquaponics system for growing nutrient-dense microgreens, influenced third-year university nutrition students’ perceptions, awareness, and knowledge of local food systems, as well as their attitudes and behaviours towards sustainability and local food consumption. Pre-surveys assessed students’ baseline knowledge, attitudes, and diet quality was measured using the Australian Recommended Food Score (ARFS)(4). The hands-on activity with Farmwall, including a seeding activity and recipe development, aimed to deepen their understanding of local food systems, sustainable diets, and links to future professional practice. Post-surveys measured changes in these areas, intentions for behaviour change, and their main learnings from the activity. Quantitative data analysis included descriptive statistics, Chi-Square tests, linear regression models, and McNemar-Bowker tests. Qualitative data was analysed thematically. In the pre-survey, students (n = 58) reported limited knowledge of local food systems (60.3%) but recognised their importance (77.6%) and positive environmental impact (73.3%). Sustainable practices students valued most included purchasing minimally packaged foods (69.0%), ethically certified products (56.9%), and locally grown produce (58.6%), with less emphasis on consuming plant-based (27.6%) and organic foods (31.0%). Chi-square tests revealed that students who believed sustainable food practices were important were significantly more likely to engage in these behaviours (p < 0.05). The average ARFS diet quality score was 39.7 ± 8.4, classified as ‘excellent ‘. Linear regression revealed that engagement in sustainable practices, such as growing own food (B = 4.4; p = 0.047) and buying locally grown (B = 5.2; p = 0.029) and seasonal foods (B = 5.8; p = 0.021), was associated with significantly higher diet quality score. The Farmwall activity significantly increased students’ knowledge of local food systems (p < 0.001) and increased their intentions towards buying locally grown foods (pre = 57.9% to post = 86.8% p < 0.001) and growing their own food (pre = 36.8% to post = 78.9% p < 0.001). Post-activity responses highlighted students’ learning about the complexity of sustainability, the benefits of sustainable dietary practices, and the relationship with the future professional practice. In conclusion, an experiential learning activity with Farmwall significantly improved students’ knowledge, attitudes, and intentions regarding sustainability and local food systems. Integrating similar experiences into the curriculum could enhance theoretical knowledge with practical skills, better preparing nutrition professionals to advocate for and implement sustainable practices into future professional practice.
Pre-pregnancy obesity (ppOB) is linked to pregnancy complications and abnormal fetal growth through placental mechanisms, and long non-coding RNAs (lncRNAs) may play an epigenetic role in these processes. We investigated overall and sex-specific associations of pre-pregnancy body mass index (ppBMI), ppOB, and birthweight with placental lncRNA transcripts in two birth cohorts. Study participants were mother-child dyads recruited to the CANDLE (Memphis, TN)(n = 725) and GAPPS (Seattle and Yakima, WA)(n = 159) cohorts. Maternal ppBMI was assessed at enrollment using interviewer-administered questionnaires. LncRNAs (1,077 and 1,033 for CANDLE and GAPPS, respectively) were sequenced from placental samples collected at birth. Placental lncRNA was regressed on ppBMI, ppOB (ppBMI ≥30kg/m2), or continuous birthweight in cohort-specific weighted linear models controlling for a priori-specified confounders and experimental variables. Potential effect modification by infant-sex was examined in sex-stratified analyses and models including BMI-infant-sex interaction terms. No lncRNA transcripts were significantly associated with ppBMI, ppOB, or birthweight in primary models. Among male infants in CANDLE, expression of three lncRNA transcripts (ERVH48-1, AC139099.1, CEBPA-DT) was associated with ppBMI and one transcript (AC104083.1) with birthweight. In GAPPS, ppBMI was associated with two lncRNA transcripts (AP000879.1 and AL365203.2) among males, and birthweight was associated with 17 lncRNA transcripts (including LINC02709, KANSL1-AS1, DANCR, EPB41L4A-AS1, and GABPB1-AS1) among females. No BMI-infant-sex interactions were observed. Though many of these potential associations are for uncharacterized transcripts, several identified lncRNAs (e.g., ERVH48-1 and CEBPA-DT) have been linked to pathways controlling cancer or placental growth, trophoblast differentiation, and gene expression. These associations warrant validation in future studies.
Cardiovascular diseases (CVDs) are the leading cause of death worldwide(1). As poor diet quality is a major contributor to CVD burden; dietary intervention is recommended as a first-line approach to CVD prevention and management(2). Personalised nutrition (PN) refers to individualised nutrition care based on genetic, phenotypic, medical, and/or behavioural and lifestyle characteristics(3). Medical nutrition therapy by dietitians shares many of these principles and can be categorised as PN(4). PN may be beneficial in improving CVD risk factors and diet, however, this has not previously been systematically reviewed. The aim of this systematic review was to evaluate the effectiveness of PN interventions on CVD risk factors and diet in adults at elevated CVD risk. A comprehensive search was conducted in March 2023 across Embase, Medline, CINAHL, PubMed, Scopus and Cochrane databases, focusing on randomised controlled trials (RCTs) published after 2000 in English. Included studies tested the effect of PN interventions on adults with elevated CVD risk factors (determined by anthropometric measures, clinical indicators, or high overall CVD risk). Risk of bias was assessed using the Academy of Nutrition and Dietetics Quality Criteria checklist. Random-effects meta-analysis were conducted to explore weighted mean differences (WMD) in change or final mean values for studies with comparable data (studies with dietary counselling interventions), for outcomes including blood pressure (BP), blood lipids, and anthropometric measurements. Sixteen articles reporting on 15 unique studies (n = 7676) met inclusion criteria and were extracted. Outcomes of participants (n = 40–564) with CVD risk factors including hyperlipidaemia (n = 5), high blood pressure (n = 3), BMI > 25kg/m2 (n = 1) or multiple factors (n = 7) were reported. Results found potential benefits of PN on systolic blood pressure (SBP) (WMD −1.91 [95% CI −3.51, −0.31] mmHg), diastolic blood pressure (DBP) (WMD −1.49 [95% CI −2.39, −0.58] mmHg), triglycerides (TG) (WMD −0.18 [95% CI −0.34, −0.03] mmol/L), and dietary intake in individuals at high CVD risk. Results were inconsistent for plasma lipid and anthropometric outcomes. Dietary counselling PN interventions showed promising results on CVD risk factors in individuals at-risk individuals. Further evidence for other personalisation methods and improvements to methodological quality and longer study durations are required in future PN interventions.
