To evaluate associations of demographic and socio-economic factors with diet quality among population subgroups in Bosnia and Herzegovina (B&H).

A cross-sectional analysis of 2017 B&H dietary survey data. Diet quality was assessed by the Prime Diet Quality Score (PDQS) utilizing data from two non-consecutive 24 h diet recalls. Socio-economic variables were extracted from the 2015 B&H Household Budget Survey. Homogeneity of means across population subgroups was evaluated using multivariable regression.

B&H population survey.

A population-based sample of 853 adults.

The mean PDQS was 15·8 (range 7–28 out of a possible 42 points). In general, Bosnian adults had low PDQS due to high intakes of refined grains, high-fat dairy and processed meats, and low intakes of whole grains, nuts and fish. The PDQS was significantly higher (P < 0·0001) among older individuals (17·0) compared with those in the youngest group (14·5), among individuals living in the central and northern regions (16·5) compared with those living in the south (15·1; P < 0·0001), and among people who are married/cohabitating (16·1) v. single (14·8; P = 0·02). In energy-adjusted models, socio-economic status (P = 0·04) and tertiles of household spending (P = 0·002) were inversely associated with the PDQS.

Diet quality in this population was low. Young and middle-aged individuals, singles and those living in the south had significantly lower quality diets compared with other subgroups. Public health action is needed to promote higher consumption of whole grains, nuts and fish, and a higher variety of fruits and vegetables.

The ongoing demographic, nutritional and epidemiological transitions in sub-Saharan Africa highlight the importance of monitoring overweight and obesity. We aimed to assess the prevalence of overweight and obesity in Mozambique in 2014/2015 and compare the estimates with those obtained in 2005.

Cross-sectional study conducted in 2014/2015, following the WHO Stepwise Approach to Chronic Disease Risk Factor Surveillance (STEPS). Prevalence estimates with 95 % CI were computed for different categories of BMI and abdominal obesity, along with age-, education- and income-adjusted OR. The age-standardized prevalence in the age group 25–64 years was compared with results from a STEPS survey conducted in 2005.

Mozambique.

Representative sample of the population aged 18–64 years (n 2595).

Between 2005 and 2014/2015, the prevalence of overweight and obesity increased from 18·3 to 30·5 % (P < 0·001) in women and from 11·7 to 18·2 % (P < 0·001) in men. Abdominal obesity increased among women (from 9·4 to 20·4 %, P < 0·001), but there was no significant difference among men (1·5 v. 2·1 %, P = 0·395). In 2014/2015, the prevalence of overweight and obesity was more than twofold higher in urban areas and in women; in the age group 18–24 years, it was highest in urban women and lowest in rural men.

In Mozambique, there was a steep increase in the prevalence of overweight and obesity among adults between 2005 and 2014/2015. Overweight and obesity are more prevalent in urban areas and among women, already affecting one in five urban women aged 18–24 years.

To investigate preferences for and ease-of-use perceptions of different aspects of printed and digitally displayed photographic portion-size estimation aids (PSEA) in a low-resource setting and to document accuracy of portion-size selections using PSEA with different visual characteristics.

A convergent mixed-methods design and stepwise approach were used to assess characteristics of interest in isolation. Participants served themselves food and water, which were weighed before and after consumption to measure leftovers and quantity consumed. Thirty minutes later, data collectors administered a meal recall using a PSEA and then a semi-structured interview.

Blantyre and Chikwawa Districts in the southern region of Malawi.

Ninety-six women, aged 18–45 years.

Preferences and ease-of-use perceptions favoured photographs rather than drawings of shapes, three and five portion-size options rather than three with four virtual portion-size options, a 45° rather than a 90° photograph angle, and simultaneous rather than sequential presentation of portion-size options. Approximately half to three-quarters of participants found the portion-size options represented appropriate amounts of foods or water consumed. Photographs with three portion sizes resulted in more accurate portion-size selections (closest to measured consumption) than other format and number of portion-size option combinations. A 45° angle and simultaneous presentation were more accurate than a 90° angle and sequential presentation of images.

Results from testing PSEA visual characteristics separately can be used to generate optimal PSEA, which can improve participants’ experiences during meal recalls.

To validate digitally displayed photographic portion-size estimation aids (PSEA) against a weighed meal record and compare findings with an atlas of printed photographic PSEA and actual prepared-food PSEA in a low-income country.

Participants served themselves water and five prepared foods, which were weighed separately before the meal and again after the meal to measure any leftovers. Participants returned the following day and completed a meal recall. They estimated the quantities of foods consumed three times using the different PSEA in a randomized order.

Two urban and two rural communities in southern Malawi.

Women (n 300) aged 18–45 years, equally divided by urban/rural residence and years of education (≤4 years and ≥5 years).

Responses for digital and printed PSEA were highly correlated (>91 % agreement for all foods, Cohen’s κw = 0·78–0·93). Overall, at the individual level, digital and actual-food PSEA had a similar level of agreement with the weighed meal record. At the group level, the proportion of participants who estimated within 20 % of the weighed grams of food consumed ranged by type of food from 30 to 45 % for digital PSEA and 40–56 % for actual-food PSEA. Digital PSEA consistently underestimated grams and nutrients across foods, whereas actual-food PSEA provided a mix of under- and overestimates that balanced each other to produce accurate mean energy and nutrient intake estimates. Results did not differ by urban and rural location or participant education level.

Digital PSEA require further testing in low-income settings to improve accuracy of estimations.

To explore the dietary habits, nutrient adequacies and dietary change experiences of immigrant and refugee children.

Mixed-methods cross-sectional design. Children completed three 24 h dietary recalls to determine nutrient inadequacies. Parents and service providers were interviewed to capture dietary practices.

Healthy Immigrant Children study, Saskatchewan, Canada.

Three hundred immigrant and refugee children aged 3–13 years and twenty-two parents who lived in Regina or Saskatoon for less than 5 years; twenty-four newcomer services providers.

Immigrant children had higher mean intakes of meat and alternatives, milk and alternatives, and whole grains; and consumed more vitamin B12, folate, Ca, vitamin D, Fe and Zn compared with refugee children. Refugee children were at higher risk of having inadequate intakes of folate (37 %) and Fe (18 %). Both immigrant and refugee children were at high risk of inadequate vitamin D (87 and 93 %, respectively) and Ca intakes (79 and 80 %), and a substantial portion were at risk for inadequate Zn intake (21 and 31 %). Participants mentioned challenges with maintaining a healthy traditional diet in the midst of a busy schedule, while responding to their children’s demands for foods high in fat and sugar.

Newcomer children are at risk for inadequate intakes of vitamin D, Ca and Zn, while refugee children are at additional risk for inadequate folate and Fe intakes. Newcomers to Canada may experience subtle or drastic changes in their food environment leading to dietary acculturation that includes increased consumption of foods high in sugar, salt and fat.

Bangladesh, like many emerging economies of South-East Asia, has started to experience a double burden of continuing high rates of undernutrition and increasing rates of overweight and obesity. A lack of assessment of the nutritional shift leaves a gap in current policies: the growing overweight and obesity is yet to be addressed. The present paper investigates the change in nutritional status, particularly the shift in BMI, of Bangladeshi women of reproductive age (15–49 years) and characterizes the vulnerable households for both underweight and overweight status during a period of 10 years (2004–2014).

Generalized linear mixed-effect models were fitted for both urban and rural residents to assess underweight and overweight status.

Bangladesh Demographic and Health Surveys.

Women aged 15–49 years (n 53 077).

The proportion of overweight increased during 2004–2014 from 10·7 to 25·1 % and the proportion of underweight decreased from 32·6 to 18·2 %. Prevalence of underweight status remained high in rural areas and prevalence of overweight increased rapidly in both rural and urban areas, creating a double burden. The significant contributors to this double burden were the change in women’s level of education, increased household wealth, divisional location and rapid urbanization.

The findings indicate that specific cohort- or area-based intervention policy studies in line with the UN Decade of Action on Nutrition are required to address the nutritional double burden in Bangladesh.

Low- and middle-income countries (LMIC) are increasingly experiencing the double burden of malnutrition. Studies to identify ‘double-duty’ actions that address both undernutrition and overweight in sub-Saharan Africa are needed. We aimed to identify acceptable behaviours to achieve more optimal feeding and physical activity practices among both under- and overweight children in Rwanda, a sub-Saharan LMIC with one of the largest recent increases in child overweight.

We used the Trials of Improved Practices (TIPs) method. During three household visits over 1·5 weeks, we used structured interviews and unstructured observations to collect data on infant and young child feeding practices and caregivers’ experiences with testing recommended practices.

An urban district and a rural district in Rwanda.

Caregivers with an under- or overweight child from 6 to 59 months of age (n 136).

We identified twenty-five specific recommended practices that caregivers of both under- and overweight children agreed to try. The most frequently recommended practices were related to dietary diversity, food quantity, and hygiene and food handling. The most commonly cited reason for trying a new practice was its benefits to the child’s health and growth. Financial constraints and limited food availability were common barriers. Nearly all caregivers said they were willing to continue the practices and recommend them to others.

These practices show potential for addressing the double burden as part of a broader intervention. Still, further research is needed to determine whether caregivers can maintain the behaviours and their direct impact on both under- and overweight.

To describe snacking characteristics and patterns in children and examine associations with diet quality and BMI.

Children’s weight and height were measured. Participants/adult proxies completed multiple 24 h dietary recalls. Snack occasions were self-identified. Snack patterns were derived for each sample using exploratory factor analysis. Associations of snacking characteristics and patterns with Healthy Eating Index-2010 (HEI-2010) score and BMI were examined using multivariable linear regression models.

Childhood Obesity Prevention and Treatment Research (COPTR) Consortium, USA: NET-Works, GROW, GOALS and IMPACT studies.

Predominantly low-income, racial/ethnic minorities: NET-Works (n 534, 2–4-year-olds); GROW (n 610, 3–5-year-olds); GOALS (n 241, 7–11-year-olds); IMPACT (n 360, 10–13-year-olds).

Two snack patterns were derived for three studies: a meal-like pattern and a beverage pattern. The IMPACT study had a similar meal-like pattern and a dairy/grains pattern. A positive association was observed between meal-like pattern adherence and HEI-2010 score (P for trend < 0⋅01) and snack occasion frequency and HEI-2010 score (β coefficient (95 % CI): NET-Works, 0⋅14 (0⋅04, 0⋅23); GROW, 0⋅12 (0⋅02, 0⋅21)) among younger children. A preference for snacking while using a screen was inversely associated with HEI-2010 score in all studies except IMPACT (β coefficient (95 % CI): NET-Works, −3⋅15 (−5⋅37, −0⋅92); GROW, −2⋅44 (−4⋅27, −0⋅61); GOALS, −5⋅80 (−8⋅74, −2⋅86)). Associations with BMI were almost all null.

Meal-like and beverage patterns described most children’s snack intake, although patterns for non-Hispanic Blacks or adolescents may differ. Diets of 2–5-year-olds may benefit from frequent meal-like pattern snack consumption and diets of all children may benefit from decreasing screen use during eating occasions.

To assess the effect of rural-to-urban migration on nutrition transition and overweight/obesity risk among women in Kenya.

Secondary analysis of data from nationally representative cross-sectional samples. Outcome variables were women’s BMI and nutrition transition. Nutrition transition was based on fifteen different household food groups and was adjusted for socio-economic and demographic characteristics. Stepwise backward multiple ordinal regression analysis was applied.

Kenya Demographic and Health Survey 2014.

Rural non-migrant, rural-to-urban migrant and urban non-migrant women aged 15–49 years (n 6171).

Crude data analysis showed rural-to-urban migration to be associated with overweight/obesity risk and nutrition transition. After adjustment for household wealth, no significant differences between rural non-migrants and rural-to-urban migrants for overweight/obesity risk and household consumption of several food groups characteristic of nutrition transition (animal-source, fats and sweets) were observed. Regardless of wealth, migrants were less likely to consume main staples and legumes, and more likely to consume fruits and vegetables. Identified predictive factors of overweight/obesity among migrant women were age, duration of residence in urban area, marital status and household wealth.

Our analysis showed that nutrition transition and overweight/obesity risk among rural-to-urban migrants is apparent with increasing wealth in urban areas. Several predictive factors were identified characterising migrant women being at risk for overweight/obesity. Future research is needed which investigates in depth the association between rural-to-urban migration and wealth to address inequalities in diet and overweight/obesity in Kenya.

Food insecurity (FI) is defined as uncertain access to healthy food in quantity and quality. We hypothesize that FI may be associated with greater health-care use and absenteeism because it may amplify the effect of diseases; also, FI may be associated with reduced health-care access because it reflects economic vulnerability. The present study estimates the association between FI and health-care use and access, and absenteeism.

Cross-sectional data collected in 2015–2016. Health-care use was measured as the number of consultations, taking any drug and having been hospitalized in the past year. Health-care access was measured by the suspension of medication and having fewer consultations due to financial constraints. Absenteeism was measured by the weeks of sickness leave. Binary variables were modelled as a function of FI using logistic regressions; continuous variables were modelled as a function of FI using negative binomial and zero-inflated negative binomial regressions. Covariates were included sequentially.

Portugal.

Non-institutionalized adults from the EpiDoc3 cohort (n 5648).

FI was significantly associated with health-care use before controlling for socio-economic conditions and quality of life. Moderate/severe FI was positively related to the suspension of medicines (adjusted OR = 4·68; 95 % CI 3·11, 6·82) and to having fewer consultations (adjusted OR = 3·98; 95 % CI 2·42, 6·37). FI and absenteeism were not significantly associated.

Our results support the hypothesis that FI reflects precariousness, which hinders access to health care. The greater use of health care among food-insecure people is explained by their worse quality of life and lower socio-economic condition, so that the specific role of poor nutrition is unclear.

We analysed the impact of the national general truck drivers’ strike on the availability, variety and price of foods sold by a food supply centre.

Descriptive study using secondary data to examine the percentage change in the mean price of fruits, vegetables and eggs before, during and after the strike. The strike in Brazil lasted 10 d from 21 to 30 May 2018. The drivers were on strike in order to make diesel oil tax-free and to obtain better working conditions.

The food supply centre, named CEASA-Minas Grande BH, was located in the metropolitan area of a Brazilian city.

We examined twenty types of foods.

After 10 d, there was a ~30 % reduction in the availability of all types of foods and prices increased. Foods with the highest price increases included cabbage (233·3 %), potatoes (220·0 %), papaya (160·0 %) and oranges (78·6 %). At the end of the strike, we observed reductions in the price of eggs, fruits, vegetables, roots and tubers; however, some foods remained more expensive than before the strike, including chayote (203·2 % higher), cucumber (66·7 % higher) and potatoes (60·0 % higher).

The general truck drivers’ strike was correlated with a reduction in the availability of food and, consequently, increases in price and possibly restrictions on access. The strike demonstrated the dependence of metropolises on road transportation and the conventional market. We speculate that initiatives aiming to shorten the food supply chain and promote food sovereignty and resilience of the supply circuits could be important.

To examine the impact of a community culinary coaching programme (CCCP) on cafeteria food alignment with a freshly prepared Mediterranean-style diet, and diners’ consumption habits and satisfaction.

A non-randomized, controlled, community-based participatory research programme. CCCP included eight 90 min coaching sessions with a community steering committee, 22 h of kitchen staff training, 12 h of pre-school staff training and 30 h of education for diners; control communities received no intervention. Outcomes, measured before and 12 months after programme initiation, included cafeteria food alignment with a freshly prepared Mediterranean-style diet through a food items list derived from the cafeteria food purchasing software, and adult diners’ consumption habits and satisfaction through questionnaires.

Communal cafeterias of rural kibbutzim.

Intervention: kibbutz with 493 adults and 214 children. Control: Two kibbutzim with a total of 487 adults and 206 children.

Intervention cafeteria food improved significantly in all Mediterranean index categories except nuts (legumes, wholegrain products, fish, MUFA/SFA P < 0·0001; fruits, vegetables P < 0·001; processed meats P = 0·004), and in the proportion of ultra-processed and unprocessed or minimally processed foods categories of the NOVA classification (−22 %, P < 0·001 and +7 %, P < 0·001, respectively), compared with the control community. The intervention group’s satisfaction was significantly improved in twenty-five (83 %) out of the thirty satisfaction items, compared with twelve (40 %) in the control group. No changes were identified in diners’ consumption habits in either intervention or control communities.

CCCP might be useful in improving alignment of cafeteria food with a freshly prepared Mediterranean-style diet.

To understand non-adherence to medically recommended diets among Mayans with diabetes.

Using partially sequential mixed methods, questionnaires, semi-structured brief and in-depth interviews were applied. Questionnaire data were analysed with Pearson’s χ2 and Student’s t tests and qualitative interviews with grounded theory microanalysis.

Rural, predominantly Mayan communities in Chiapas, Quintana Roo and Yucatan, Mexico, 2008–2012.

Purposive sample of Mayans with type 2 diabetes; using public health care; 168 women and twenty-seven men; age 21–50+ years.

Participants understood diabetes as caused by negative emotions, divine punishment, revenge via spells, chemicals in food and high sugar/fat consumption. Eliminating corn, pork, sugary beverages and inexpensive industrialized foods was perceived as difficult or impossible. More Mayans reporting not understanding physician instructions (30 v. 18 %) reported difficulty reducing red meat consumption (P = 0·051). Non-adherence was influenced by lack of patient–provider shared knowledge and medical recommendations misaligned with local culture. Men whose wives prepared their meals, women who liked vegetables and young adults whose mothers prepared their meals reported greater adherence to dietary recommendations. Partial adherents said it made life tolerable and those making no physician-recommended dietary changes considered them too restrictive (they meant ‘starving to death’). Over half (57 %) of participants reported non-adherence; the two principal reasons were dislike of recommended foods (52·5 %) and high cost (26·2 %).

Adherence to dietary regimens in diabetes treatment is largely related to social and cultural issues. Taking cultural diversity, food preferences, local food availability and poverty into consideration is essential when developing health-promotion activities related to diabetes.

To evaluate the association between three behavioural economics ‘nudges’ and store sales of promoted healthier foods.

Multiple interrupted time series.

Two predominantly rural counties in central North Carolina, USA.

Aggregated store transaction data from two grocery stores (one intervention, one control) and two convenience stores (one intervention, one control) were analysed using ANOVA to examine the association between three ‘nudges’ and store sales of promoted items. The nudges included: a ‘cognitive fatigue’ experiment, in which floor arrows guided customers to the produce sections; a ‘scarcity’ experiment, in which one sign in one area of the produce section portrayed a ‘limited amount’ message; and a ‘product placement’ experiment, where granola bars were moved into the candy bar aisle.

In convenience stores, there were no significant differences between sales of the promoted items during the intervention period for any of the nudges when implemented individually. However, compared with baseline sales, implementation of all three nudges simultaneously was associated with an increase in sales during the intervention period based on proportional computations (P = 0·001), whereas no significant changes in sales were observed in the control convenience store. Among the grocery stores, there were no significant differences in sales during the intervention period for any of the nudges or the combined intervention compared with baseline sales.

Implementing three nudges concurrently in a convenience store setting may increase sales of promoted items. However, before stores consider implementing these nudges to increase sales of nutritious foods, additional research is warranted.

The purpose of this evaluation study was to identify strengths and opportunities for improvement in programme functioning and common aspects of patients’ experiences at a hospital-based food pantry.

Semi-structured, in-depth interviews with patients and a cross-sectional survey for providers were used. Interview transcripts were coded using both inductive and deductive approaches and assessed for inter-rater reliability. Descriptive statistics were produced from quantitative data.

An academic urban safety-net hospital in the Northeastern US offering inpatient and outpatient services.

Thirty patients and 89 providers.

Patients expressed feeling comfortable, trusting the food, high satisfaction with food quality, convenience, and lack of stigma at the hospital-based pantry. Patients mentioned the pantry helped them eat more fruits and vegetables, but expressed concerns about the healthfulness of other foods distributed. Providers believed they should discuss food insecurity (FI) with patients (99 %) and that the pantry improves the health of patients (97 %), but faced barriers to consistently screening for FI and referring patients to the pantry, such as insufficient training on FI (53 %) and time constraints (35 %).

Findings suggest hospital-based food pantries may have several advantages. Hospitals with onsite food pantries must work to eliminate barriers to FI screening and pantry referral. To optimize their impact, such pantries should develop nutritional guidelines for food donations and connect patients with nutrition education resources. Future research should examine health outcomes for patients using hospital-based food pantries.

To examine the pattern and correlates of public support for twelve public health interventions aimed at reducing sugar-sweetened beverage (SSB) consumption.

Cross-sectional population-based survey. Respondents were recruited using a random digit dialling procedure (landline telephone) and a random selection of telephone numbers (mobile telephone). Sampling quotas were applied for age, and the sample was stratified according to administrative regions.

The province of Québec, Canada.

One thousand adults aged between 18 and 64 years and able to answer the survey questionnaire in French or English.

Support was observed for a number of public health interventions, but the more intrusive approaches were less supported. Support for taxation as well as for sale and access restriction was positively associated with the perceived relevance of the government intervention, perceived effectiveness, and perceived associations between SSB consumption and chronic diseases. Believing that SSB consumption is a personal choice and daily consumption were generally negatively associated with strong support and positively associated with strong opposition. Sparse associations between sociodemographic and socio-economic characteristics were observed, with the exception of sex and age: women were generally more likely to support the examined public health strategies, while younger respondents were less likely to express support.

Increasing perceived effectiveness and government responsibility for addressing the issue of SSB consumption could lead to increased support for SSB interventions. Increasing the belief that SSB consumption could be associated with chronic diseases would increase support, but SSB consumers and younger individuals are expected to be resistant.

To determine whether school-level participation in the federal Community Eligibility Provision (CEP), which provides free school lunch to all students, is associated with school meal participation rates. Participation in school meals is important for decreasing food insecurity and improving child health and well-being.

Quasi-experimental evaluation using negative binomial regression to predict meal count rates per student-year overall and by reimbursement level adjusted for proportion eligible for free and reduced-price lunch (FR eligibility) and operating days.

Schools (grades kindergarten to 12th) participating in the National School Lunch Program (NSLP) in Maryland and Pennsylvania, USA, from the 2013–2015 (n 1762) and 2016–2017 (n 2379) school years.

Administrative, school-level data on school lunch counts and student enrolment.

CEP was associated with a non-significant 6 % higher total NSLP meal count adjusting for FR eligibility, enrolment and operating days (rate ratio = 1·06, 95 % CI 0·98, 1·14). After controlling for participation rates in the year prior to CEP implementation, the programme was associated with a significant 8 % increase in meal counts (rate ratio = 1·08, 95 % CI 1·03, 1·12). In both analyses, CEP was associated with lower FR meal participation and substantial increases in paid meal participation.

School-level implementation of CEP is associated with increases in total school meal participation. Current funding structures may prevent broader adoption of the programme by schools with fewer students eligible for FR meals.

The objective of this study was to examine climate impact from diet across background and sociodemographic characteristics in a population-based cohort in northern Sweden.

A cross-sectional study within the Västerbotten Intervention Programme. Dietary data from a 64-item food frequency questionnaire collected during 1996–2016 were used. Energy-adjusted greenhouse gas emissions (GHGE) for all participants, expressed as kg carbon dioxide equivalents/day and 4184 kJ (1000 kcal), were estimated using data from life cycle analyses. Differences in background and sociodemographic characteristics were examined between participants with low and high GHGE from diet, respectively. The variables evaluated were age, BMI, physical activity, marital status, level of education, smoking, and residence.

Västerbotten county in northern Sweden.

In total, 46 893 women and 45 766 men aged 29–65 years.

Differences in GHGE from diet were found across the majority of examined variables. The strongest associations were found between GHGE from diet and age, BMI, education, and residence (all P < 0·001), with the highest GHGE from diet found among women and men who were younger, had a higher BMI, higher educational level, and lived in urban areas.

This study is one of the first to examine climate impact from diet across background and sociodemographic characteristics. The results show that climate impact from diet is associated with age, BMI, residence and educational level amongst men and women in Västerbotten, Sweden. These results define potential target populations where public health interventions addressing a move towards more climate-friendly food choices and reduced climate impact from diet could be most effective.
