Examine the extent and nature of food and non-alcoholic drink advertising displayed on public transport and infrastructure on school routes.
Design:
Audit of outdoor advertisements on government-controlled public transport and associated infrastructure (e.g., tram shelters, bus stops) on busy school routes in Victoria, Australia. Using a strict protocol, trained field workers collected data on the type and content of outdoor advertising during February 2023 (start of school year). Food/drink advertising was classified (unhealthy or healthy) according to the Council of Australian Governments Health Council National interim guide to reduce children’s exposure to unhealthy food and drink promotion (2018).
Setting:
Government-controlled buses, trams and public transport infrastructure on routes from eleven of the busiest train stations in metropolitan Melbourne and regional Victoria, Australia to 50 public primary and secondary. Stations were chosen based on annual patronage, area-based socioeconomic status (SEA) and regionality)
Results:
156 out of 888 advertisements were for food and non-alcoholic drinks. Of these, almost six in ten (58%) were deemed unhealthy irrespective of SEA or regionality. Marketing appeals most featured were taste (31%), convenience (28%) and emotion (9%). A significantly higher proportion of unhealthy advertisements were displayed within 500m of schools versus outside this radius (91% vs 57%, p<0.01).
Conclusion:
Given detrimental impacts of exposure to unhealthy food/drink advertising on children’s diets, the pervasive, powerful presence of such advertising across government public transport assets, particularly around schools, contradicts public health recommendations to protect children from exposure to and influence by this harmful marketing and warrants government action.
Australia has a diverse and unique native flora with thousands of edible plant taxa, many of which are wild relatives of important food crops. These have the potential to diversify and improve the sustainability of Australian farming systems. However, the current level of domestication and cultivation of Australian plants as food crops is extremely limited by global standards. This review examines the current status and potential for future de novo domestication and large-scale cultivation of Australian plants as food crops. This is done in the context of international new crop development and factors that impact the success or failure of such efforts. Our review finds considerable potential for native Australian plants to be developed as food crops, but the industry faces several significant challenges. The current industry focuses on niche food markets that are susceptible to oversupply. It also suffers from inconsistent quantity and quality of product, which is attributed to a reliance on wild harvesting and the cultivation of unimproved germplasm. More active cultivation is necessary for industry growth, but attempts have historically failed due to poorly adapted germplasm and a lack of agronomic information. The de novo domestication and large-scale cultivation of Australian plants as food crops will require an investment in publicly supported multidisciplinary research and development programmes. Research programmes must prioritize the exploration of plants throughout Australia and the collection and evaluation of germplasm. Programmes must also seek to engage relevant stakeholders, pursue participatory research models and provide appropriate engagement and benefit-sharing opportunities with Indigenous Australian communities.
The past decade has seen a growth in research into the social determinants of health. This research challenges the assumptions that investments in the health system and lifestyle behaviours are responsible for health gains. By focusing on inequalities in health, the research has shed light on a range of factors that influence health. This book covers the differential health impacts of family and early development, changes in work and work conditions, health systems, the physical environment of cities, indigenous peoples, rural populations, social capital, culture, and global economic and environmental changes. It contains material that explains how inequality gets 'under the skin', through describing the physiological changes that follow from stress and behaviours. Particularly important is the 'natural experiment' represented by the different political and economic paths taken by Australia and New Zealand over the past two decades and the opportunity this provides to assess the impact on health.
The Comprehensive Assessment of Neurodegeneration and Dementia (COMPASS-ND) cohort study of the Canadian Consortium on Neurodegeneration in Aging (CCNA) is a national initiative to catalyze research on dementia, set up to support the research agendas of CCNA teams. This cross-country longitudinal cohort of 2310 deeply phenotyped subjects with various forms of dementia and mild memory loss or concerns, along with cognitively intact elderly subjects, will test hypotheses generated by these teams.
Methods:
The COMPASS-ND protocol, initial grant proposal for funding, fifth semi-annual CCNA Progress Report submitted to the Canadian Institutes of Health Research December 2017, and other documents supplemented by modifications made and lessons learned after implementation were used by the authors to create the description of the study provided here.
Results:
The CCNA COMPASS-ND cohort includes participants from across Canada with various cognitive conditions associated with or at risk of neurodegenerative diseases. They will undergo a wide range of experimental, clinical, imaging, and genetic investigation to specifically address the causes, diagnosis, treatment, and prevention of these conditions in the aging population. Data derived from clinical and cognitive assessments, biospecimens, brain imaging, genetics, and brain donations will be used to test hypotheses generated by CCNA research teams and other Canadian researchers. The study is the most comprehensive and ambitious Canadian study of dementia. Initial data posting occurred in 2018, with the full cohort to be accrued by 2020.
Conclusion:
Availability of data from the COMPASS-ND study will provide a major stimulus for dementia research in Canada in the coming years.
There is evidence for the cost-effectiveness of health visitor (HV) training to assess postnatal depression (PND) and deliver psychological approaches to women at risk of depression. Whether this approach is cost-effective for lower-risk women is unknown. There is a need to know the cost of HV-delivered universal provision, and how much it might cost to improve health-related quality of life for postnatal women. A sub-study of a cluster-randomised controlled trial in the former Trent region (England) previously investigated the effectiveness of PoNDER HV training in mothers at lower risk of PND. We conducted a parallel cost-effectiveness analysis at 6-months postnatal for all mothers with lower-risk status attributed to an Edinburgh Postnatal Depression Scale (EPDS) score <12 at 6-weeks postnatal.
Methods
Intervention HVs were trained in assessment and cognitive behavioural or person-centred psychological support techniques to prevent depression. Outcomes examined: quality-adjusted life-year (QALY) gains over the period between 6 weeks and 6 months derived from SF-6D (from SF-36); risk-of-depression at 6 months (dichotomising 6-month EPDS scores into lower risk (<12) and at-risk (⩾12).
Results
In lower-risk women, 1474 intervention (63 clusters) and 767 control participants (37 clusters) had valid 6-week and 6-month EPDS scores. Costs and outcomes data were available for 1459 participants. 6-month adjusted costs were £82 lower in intervention than control groups, with 0.002 additional QALY gained. The probability of cost-effectiveness at £20 000 was very high (99%).
Conclusions
PoNDER HV training was highly cost-effective in preventing symptoms of PND in a population of lower-risk women and cost-reducing over 6 months.
To examine socio-economic status (SES) and time-related factors associated with less healthy food purchases in Australia.
Design
Data were from the 2009/10 Household Expenditure Survey (HES) conducted by the Australian Bureau of Statistics. Regression analysis was used to examine the associations between the proportion of the household food budget spent on various food types (processed and unprocessed foods, foods purchased from takeaways and restaurants) and SES and time constraint variables.
Setting
Australia, 2009–2010.
Subjects
Nationally representative sample of Australian households.
Results
Household income seems to be the most important correlate with food expenditure patterns once other SES indicators are controlled for. Time constraints appear to explain some, but not all, of the adjusted SES gradients in food expenditure. Comparing home food consumption categories (processed and unprocessed foods) with foods purchased away from home (takeaway and restaurant foods) shows that wealthier, more highly educated and least disadvantaged households spend relatively less of their total food budget on processed and unprocessed foods prepared at home and more on foods purchased away from home at restaurants.
Conclusions
Simple SES gradients in dietary behaviour are influenced by correlations between different SES indicators and between SES and time constraints. Examining these factors separately obscures some of the possible causal effects of disadvantage on healthy eating. When formulating policy responses to unhealthy diets, policy makers should consider alternative sources of disadvantage, including time pressure.
To investigate trends in five key aspects of Australian food practice which have been implicated in diet-related health risks, specifically energy intake. They are: the replacement of home-prepared foods by commercially prepared foods; consumer reliance on ultra-processed foods; de-structured dining; increased pace of eating; and a decline in commensal eating.
Design
Data were from repeated cross-sections from the national Household Expenditure and Time Use Surveys. Trends in food practice aspects were examined using indicators of food expenditure across different food groups and time spent eating and cooking, including where, when and with whom eating activities took place.
Setting
Australia, 1989–2010.
Subjects
Nationally representative samples of Australian households.
Results
The share of the total food budget spent on food away from home rose steadily from 22·8 % in 1989 to 26·5 % in 2010, while spending on ultra-processed foods increased. The basic patterning of meals and the pace of eating changed little, although people spent more time eating alone and at restaurants. Cooking time declined considerably, particularly for women.
Conclusions
These changes have occurred over the same time that obesity and diet-related, non-communicable diseases have increased rapidly in Australia. Some aspects are implicated more than others: particularly the shift from domestic cooking to use of pre-prepared and ultra-processed foods, a reduction in time spent in food preparation and cooking, as well as an upsurge in time and money devoted to eating away from home. These are all likely to operate through the higher energy content of commercially prepared, compared with unprocessed or lightly processed, foods.
In our context, existential plight refers to heightened concerns about life and death when people are diagnosed with cancer. Although the duration of existential plight has been proposed to be approximately 100 days, evidence from longitudinal studies raises questions about whether the impact of a diagnosis of advanced cancer may require a longer period of adjustment. The purpose of our study was to examine spiritual well-being (SpWB) and quality of life (QoL) as well as their interrelationship in 52 patients with advanced cancer after 100 days since the diagnosis at one and three months post-baseline.
Method:
The study was designed as a secondary data analysis of a cluster randomized clinical trial involving patients with stage 3 or 4 cancer undergoing treatment. SpWB was measured using the 12-item Functional Assessment of Chronic Illness Therapy–Spiritual Well-Being Scale (FACIT–Sp–12); common factor analyses revealed a three-factor pattern on the FACIT–Sp–12. Quality of life was measured with the Functional Assessment of Cancer Therapy–General (FACT–G). We limited our sample to participants assigned to the control condition (n = 52).
Results:
SpWB and QoL remained stable between one and three months post-baseline, which were a median of 112 and 183 days after diagnosis, respectively. SpWB was found to be associated with QoL more strongly than physical and emotional well-being. Peace and Meaning each contributed unique variance to QoL, and their relative importance shifted over time. Faith was positively related to QoL initially. This association became insignificant at three months post-baseline.
Significance of results:
This study underscores the significance of SpWB for people newly diagnosed with advanced cancer, and it highlights the dynamic pattern of Peace, Meaning, and Faith in association with QoL. Our results confirm that patients newly diagnosed with advanced cancer experience an existential crisis, improve and stabilize over time. Future studies with larger samples over a longer period of time are needed to verify these results.
Distress screening guidelines call for rapid screening for emotional distress at the time of cancer diagnosis. The purpose of this study was to examine the distress thermometer's (DT) ability to screen in patients in treatment for advanced cancer who may be depressed.
Methods:
Using cross-sectional data collected from patients within 30 days of diagnosis with advanced cancer, this study used ROC analysis to determine the optimal-cutoff point of the distress thermometer (DT) for screening for depression as measured by the physician health questionnaire (PHQ)-9; inter-test reliability analysis to compare the DT with the PHQ-2 for screening in possible cases of depression, and multivariate analysis to examine associations among the DT emotional problem list (EPL) items with cases of depression.
Results:
The average age of the 123 patients in the study was 59.9 (12.9) years. Seventy (56.9%) were female. All had Stage 3 or 4 cancers (40% gastrointestinal, 19% gynecologic, 20% head and neck, 21% lung). The mean DT score was 4 (2.7)/10; and 56 (43%) were depressed as measured by the PHQ-9 ≥5. The optimal DT cut-off score to screen in possible cases of depression was ≥2/10, with a sensitivity of .96, compared to a sensitivity of .32 of the PHQ-2 ≥2. Correlation coefficients for the DT ≥2 and the PHQ-2 with the PHQ-9 ≥5 were 0.4 and −0.2, respectively. EPL items associated with cases of depression were Depression (OR = 0.15, 0.02–0.85) and Sadness (OR = 0.21, 0.06–0.72).
Significance of Results:
The optimal DT threshold for identifying possible cases of depression at the time of diagnosis is ≥2; this threshold is more sensitive than the PHQ-2 ≥2. EPL items may be used with the DT score to triage patients for evaluation.
To investigate evolving food retail systems in Thailand.
Design
Rapid assessment procedures based on qualitative research methods including interviews, focus groups discussions and site visits.
Setting
Seven fresh markets located in the four main regions of Thailand.
Subjects
Managers, food specialists, vendors and shoppers from seven fresh markets who participated in interviews and focus group discussions.
Results
Fresh markets are under economic pressure and are declining in number. They are attempting to resist the competition from supermarkets by improving convenience, food diversity, quality and safety.
Conclusions
Obesity has increased in Thailand at the same time as rapid growth of modern food retail formats has occurred. As fresh markets are overtaken by supermarkets there is a likely loss of fresh, healthy, affordable food for poorer Thais, and a diminution of regional culinary culture, women's jobs and social capital, with implications for the health and nutrition transition in Thailand.
A preliminary investigation into different eating patterns among Thai consumers who shop at fresh markets as opposed to supermarkets in Chiang Mai.
Design
A short questionnaire adopted from a previous study was administered to the forty-four participants, who comprised supermarket users, fresh market users and people who consistently shopped at both supermarkets and fresh markets.
Setting
Participants were recruited within four fresh markets and two food courts attached to supermarkets in Chiang Mai.
Subjects
Chiang Mai residents who agreed to participate in the study. Equal numbers were regular fresh market and supermarket users.
Results
Initial results suggest an association between shopping at supermarkets and attributing bread with culinary value.
Conclusions
Supermarkets may be potentially significant players in the ‘nutrition transition’, providing Thais more convenient shopping at some cost to their healthy food choices.
There is an increasing demand upon radiology departments for use of ultrasound as part of triple assessment of symptomatic breast disease. It has been shown that in the context of proper training both surgeons and radiologists achieve comparably high diagnostic sensitivity and specificity with ultrasound. This article outlines the arguments in favour of the use of ultrasound by surgeons in the breast clinic for diagnostic and therapeutic purposes.
Cerebral palsy (CP) can occur in term infants with or without preceding newborn encephalopathy. We compared the type and severity of CP and associated disability in these two groups. Participants from a population-based case-control study of term newborn encephalopathy were followed up for 6 years and linked to the Western Australian Cerebral Palsy Register. The remaining term infants with CP for the same period were also identified from the Cerebral Palsy Register. 13% of neonatal survivors of term newborn encephalopathy had CP, a rate of 116 per 1000 term live births. Overall, 24% of term infants with CP followed newborn encephalopathy. CP following newborn encephalopathy was more likely to: affect males (72% vs 56%); be severe (47% vs 25%); and be of spastic quadriplegia or dyskinetic types. Cognitive impairment was more common (75% vs 43%) and severe (41% vs 16%), as was epilepsy (53% vs 29%) in survivors of encephalopathy. These children were also more likely to: be non-verbal (47% vs 22%); have a severe composite disability score (47% vs 26%); and die between time of diagnosis of CP and age 6 years (5-year cumulative mortality 19% vs 5%). Children born at term who develop CP following newborn encephalopathy have a poorer prognosis than those with CP who were not encephalopathic in the first week of life.

Health inequalities exist in every country in which they have heen assessed hut action to tackle them has, with a few exceptions, been conspicuous hy its absence (McKee and Jacobson 2000, p 668).
Introduction
We are entering the 21st century with two bodies of evidence that raise fundamental issues about the role of governments and scientists in promoting health and well-being. The first reveals enormous gains made during the 20th century in extending life expectancy for a majority of citizens in the world. At the same time, numerous studies confirm the persistence of social gradients of health for many diseases, as well as increasing social gradients for diseases for which the gap had been narrowing in the 1970s and 1980s. Woodward and colleagues (this volume) provide one illustration, with evidence of a recent mortality cross-over between Australia and New Zealand, due to uneven health improvements of different ethnic groups in New Zealand compared to the average improvement made by Australia's population. This loss of hard-won health gains by some New Zealanders is not confined to that country, with similar findings being reported for parts of Eastern Europe and for regions in rural Australia (Bobâk et al. 2000a; Burnley 1998).
In the last couple of years, bodies like the International Society for Equity in Health, the International Poverty and Health Network and the Global Equity Gauge Initiative have been established by scientists and public health practitioners (International Society for Equity in Health Constitution 2000; Heath et al. 2000; Rockefeller Foundation 2000). These action groups are responding to a general lack of government commitment in the area of health inequalities. They share a common aim to produce evidence on which to base interventions that will reduce inequalities in health within and between countries.
Their attention is well directed. A search of the literature for evidence of systematic attempts by governments in this area reveals few examples. (Finland, the Netherlands and, very recently, the UK are notable exceptions.) What it does reveal is enormous national variation with respect to policy (in) action (Hupalo and Herden 1999; Acheson 1998; WHO 2000; New Zealand Ministry of Health 2000b; Mackenbach et al. 1999).
