To examine public commitments for encouraging United States consumers to make healthy dietary purchases with their Supplemental Nutrition Assistance Program (SNAP) benefits among of prevalent SNAP-authorised retailers.

National SNAP-authorised retail landscape in addition to stores located in California and Virginia, two states targetted for a Partnership for a Healthier America pilot social marketing campaign.

SNAP-authorised retailers with the most store locations in selected settings.

A review of retailers’ publicly available business information was conducted (November 2016–February 2017). Webpages and grey literature sources were accessed to identify corporate social responsibility (CSR) reports and commitments describing strategies to encourage healthy consumer purchases aligned with the 2015–2020 Dietary Guidelines for Americans. Evidence was organised using a marketing-mix and choice-architecture (MMCA) framework to characterise strategies used among eight possible types (i.e. place, profile, portion, pricing, promotion, priming, prompting and proximity).

Of the SNAP-authorised retailers (n 38) reviewed, more than half (n 20; 52·6 %) provided no information in the public domain relevant to the research objective. Few retailers (n 8; 21·1 %) had relevant CSR information; grey literature sources (n 52 articles across seventeen retailers) were more commonly identified. SNAP-authorised retailers in majority committed to increasing the number of healthy products available for purchase (profile).

Substantial improvements are needed to enhance the capacity and commitments of SNAP-authorised retailers to use diverse strategies to promote healthy purchases among SNAP recipients. Future research could explore feasible approaches to improve dietary behaviours through sector changes via public–private partnerships, policy changes, or a combination of government regulatory and voluntary business actions.

We aimed to estimate the cost-effectiveness of brief weight-loss counselling by dietitian-trained practice nurses, in a high-income-country case study.

A literature search of the impact of dietary counselling on BMI was performed to source the ‘best’ effect size for use in modelling. This was combined with multiple other input parameters (e.g. epidemiological and cost parameters for obesity-related diseases, likely uptake of counselling) in an established multistate life-table model with fourteen parallel BMI-related disease life tables using a 3 % discount rate.

New Zealand (NZ).

We calculated quality-adjusted life-years (QALY) gained and health-system costs over the remainder of the lifespan of the NZ population alive in 2011 (n 4·4 million).

Counselling was estimated to result in an increase of 250 QALY (95 % uncertainty interval −70, 560 QALY) over the population’s lifetime. The incremental cost-effectiveness ratio was 2011 $NZ 138 200 per QALY gained (2018 $US 102 700). Per capita QALY gains were higher for Māori (Indigenous population) than for non-Māori, but were still not cost-effective. If willingness-to-pay was set to the level of gross domestic product per capita per QALY gained (i.e. 2011 $NZ 45 000 or 2018 $US 33 400), the probability that the intervention would be cost-effective was 2 %.

The study provides modelling-level evidence that brief dietary counselling for weight loss in primary care generates relatively small health gains at the population level and is unlikely to be cost-effective.

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 assess the prevalence and determinants of food insecurity among people living with HIV (PLWH) in Pune, India and its association with biomarkers known to confer increased risks of morbidity and mortality in this population.

Cross-sectional analysis assessing food insecurity using the standardized Household Food Insecurity Access Scale. Participants were dichotomized into two groups: food insecure and food secure. Logistic regression models were used to assess associations between socio-economic, demographic, clinical, biochemical factors and food insecurity.

Antiretroviral therapy (ART) centre of Byramjee Jeejeebhoy Government Medical College and Sassoon General Hospitals (BJGMC–SGH), Pune, a large publicly funded tertiary and teaching hospital in western India.

Adult (≥18 years) PLWH attending the ART centre between September 2015 and May 2016 who had received ART for either ≤7d (ART-naïve) or ≥1 year (ART-experienced).

Food insecurity was reported by 40 % of 483 participants. Independent risk factors (adjusted OR; 95 % CI) included monthly family income <INR 5000 (~70 USD; 13·2; CI 5·4, 32·2) and consuming ≥4 non-vegetarian meals per week (4·7; 1·9, 11·9). High-sensitivity C-reactive protein (hs-CRP) ≥0·33 mg/dl (1·6; 1·04, 2·6) and d-dimer levels 0·19–0·31 µg/ml (1·6; 1·01, 2·6) and ≥0·32 µg/ml (1·9; 1·2, 3·2) were also associated with food insecurity.

More than a third of the study participants were food insecure. Furthermore, higher hs-CRP and d-dimer levels were associated with food insecurity. Prospective studies are required to understand the relationship between food insecurity, hs-CRP and d-dimer better.

Efforts to improve the nutritional quality and health promotion in the charitable food system have been undertaken. Though methods exist to track these efforts in terms of food banks’ inventory, there are not research-tested tools to assess, monitor and influence policy, systems and environmental (PSE) changes. The study objective was to develop and evaluate a novel assessment tool that could be used to evaluate a food bank’s efforts to improve the promotion of health and nutritious foods.

The study had five phases: (1) initial development; (2) iterative review and revisions; (3) pilot testing; (4) content validity assessment and (5) inter-rater and test-retest assessment. The Food Bank Health and Nutrition Assessment (FB-HANA) was drafted after reviewing existing policies, nutrition-focused charitable food systems guidance and similar tools for food pantries.

Midwestern United States.

Eleven food banks.

Stakeholders and pilot testers provided initial feedback to refine the FB-HANA’s flow, ease of completion and collection of contextual information. External experts rated the FB-HANA and each of the eight objectives as content valid. A set of two assessments completed by twenty-six community-based professionals, employed by Extension and fourteen food bank staff across eleven food banks, supported moderate to excellent inter-rater and test-retest reliability for the FB-HANA overall and each of its objectives.

Evidence suggests that the FB-HANA can be used by either food bank or community-based professionals, such as Extension staff, to provide a perspective on ways food banks promote health and nutrition through PSE approaches.

We aimed to investigate the associations between dietary branched-chain amino acids (BCAA) intake and long-term risks of CVD, cancer and all-cause mortality in nationwide survey participants aged ≥ 18.

This was a prospective cohort study. Dietary intakes of BCAA (leucine, isoleucine and valine) were determined from the total nutrient intake document. The main outcomes were CVD, cancer and all-cause mortality.

A nationally representative sample of US adults were recruited by the National Center for Health Statistics (NCHS) from 1988 to 1994.

A total of 14 397 adults aged ≥ 18 who participated in the United States National Health and Nutrition Examination Survey III (NHANES III) were included.

During 289 406 person-years of follow-up, we identified 4219 deaths, including 1133 from CVD and 926 from cancer. After multivariate adjustment, the hazard ratios (95 % confidence intervals) of all-cause mortality in the highest dietary BCAA and isoleucine intake quintile (reference: lowest quintiles) were 0·68 (0·48, 0·97) and 0·68 (0·48, 0·97), respectively. Each one-standard-deviation increase in total dietary BCAA or isoleucine intake was associated with an 18 % or 21 % decrease in the risk of all-cause mortality, respectively. The serum triglyceride (TAG) concentration was found to modify the association between the dietary BCAA intake and all-cause mortality (Pfor interaction = 0·008).

In a nationally representative cohort, higher dietary intakes of BCAA and isoleucine were independently associated with a lower risk of all-cause mortality, and these associations were stronger in participants with higher serum TAG concentrations.

During the COVID-19 pandemic, the authorities made a change in the classification of malnutrition and concomitant service delivery protocol among the Rohingya children, residing in world’s largest refugee camp, located in Cox’s Bazar, Bangladesh. In this paper, we discussed the potential implications of this updated protocol on the malnutrition status among children residing in the Rohingya camps.

This paper reviewed relevant literature and authors’ own experience to provide a perspective of the updated protocol for the classification of malnutrition among the children in the Rohingya camps and its implication from a broader perspective.

Rohingya refugee camps, Bangladesh.

Children aged less than five years residing in the Rohingya camps.

Major adaptation during this COVID-19 was the discontinuation of using weight-for-height z-score (WHZ) and the use of only mid upper arm circumference (MUAC) and presence of oedema for admission, follow-up and discharge of malnourished children in the camps. However, evidence suggests that use of MUAC only can underestimate the prevalence of malnutrition among the children in Rohingya camps. These apparently non-malnourished children are devoid of the rations that they would otherwise receive if classified as malnourished, making them susceptible to more severe malnutrition.

Our analysis suggests that policymakers should consider using the original protocol of using both MUAC and WHZ to classify malnutrition and retain the guided ration size. We also believe that it would not take an extra effort to adopt the original guideline as even with MUAC only guideline, certain health measures needed to adopt during this pandemic.

Recent meta-analyses demonstrate that small-quantity lipid-based nutrient supplements (SQ-LNS) for young children significantly reduce child mortality, stunting, wasting, anaemia and adverse developmental outcomes. Cost considerations should inform policy decisions. We developed a modelling framework to estimate the cost and cost-effectiveness of SQ-LNS and applied the framework in the context of rural Uganda.

We adapted costs from a costing study of micronutrient powder (MNP) in Uganda, and based effectiveness estimates on recent meta-analyses and Uganda-specific estimates of baseline mortality and the prevalence of stunting, wasting, anaemia and developmental disability.

Rural Uganda.

Not applicable.

Providing SQ-LNS daily to all children in rural Uganda (> 1 million) for 12 months (from 6 to 18 months of age) via the existing Village Health Team system would cost ∼$52 per child (2020 US dollars) or ∼$58·7 million annually. SQ-LNS could avert an average of > 242 000 disability-adjusted life years (DALYs) annually as a result of preventing 3689 deaths, > 160 000 cases of moderate or severe anaemia and ∼6000 cases of developmental disability. The estimated cost per DALY averted is $242.

In this context, SQ-LNS may be more cost-effective than other options such as MNP or the provision of complementary food, although the total cost for a programme including all age-eligible children would be high. Strategies to reduce costs, such as targeting to the most vulnerable populations and the elimination of taxes on SQ-LNS, may enhance financial feasibility.

The aim of this cross-sectional study was to examine the association between childhood obesity and modifiable population-level risk factors, after accounting for deprivation.

A review of the literature identified population-level risk factors including a healthy childcare setting, the local food environment, accessible open space, community safety and crime. Data for these risk factors were then identified and matched by each of the twenty-two local government areas in Wales to each child that had data on height and weight in the Wales Childhood Measurement Programme (CMP) (2012–2017). Multivariable logistic regression was used to identify associations with childhood obesity.

The current study was undertaken in Wales, UK, where approximately one in eight 4–5-year-olds are classified as obese.

All participants were children aged 4 or 5 years who attend school, measured as part of the CMP, between 2012 and 2017 (n 129 893, mean age 5·0 (sd 0·4) years).

After adjusting for deprivation, small but statistically significant associations were found between childhood obesity and percentage of land available as accessible open space OR 0·981 (95 % CI: 0·973, 0·989) P < 0·001) and density of fast food outlets OR 1·002 (95 % CI 1·001, 1·004, P = 0·001). No other population-level risk factors were associated with childhood obesity.

The current study indicates that, even after accounting for deprivation, risk factors such as the density of fast food outlets and access to green space should be considered when tackling childhood obesity as a public health issue.

To evaluate the successes and shortcomings of the community service programme implemented by the Department of Health (DOH) in South Africa by evaluating community service dietitians’ experiences and challenges during the 2009 community service year.

The study employed both quantitative and qualitative research designs. A national survey was conducted using a questionnaire to illicit information on community service dietitians’ working environments and the challenges they experienced. Furthermore individual interviews were conducted with a purposively selected subsample of community service dietitians to further explore issues that arose in the survey.

Data were collected from community service dietitians in the public health sector in South Africa.

Dietitians completing their community service year in 2009.

Of the 168 community service dietitians placed in 2009, 134 (80 %) participated in the survey, while five community service dietitians in each province (n 45) were interviewed. Overall the community service dietitians were positive about the community service year and reported that it improved their confidence, skills and competencies. However, they experienced challenges related to the orientation programme, supervision/mentoring, resources available, patient referrals and communication.

Despite the overall success of the community service year there are still challenges which the DOH needs to address in order to provide the best nutrition service possible for its patients.

There is increasing pressure for adolescents to be thin and this may not always be acted upon in healthy ways; for example, certain foods or food groups may be restricted or meals skipped. As foods are not eaten in isolation it is useful to examine dietary patterns and associated psychosocial factors to better understand eating behaviour. The aim of the present study was to identify correlates of ‘dieting’ in adolescents from Otago, New Zealand.

A web-based survey was conducted in 2009, collecting information on food consumption and factors potentially associated with food consumption. Principal components analysis was used to investigate dietary patterns. Correlates were examined in 1329 students using multiple logistic regression analysis.

Nineteen secondary schools in the province of Otago, New Zealand.

Students from school years 9 and 10 (mean age 14·1 (sd 0·7) years).

There was no relationship between dieting and dietary patterns. Those not dieting were 17 % (95 % CI 7, 26 %) more likely to eat lunch and 22 % (95 % CI 3, 37 %) more likely to eat an evening meal on one more weekday than those who were dieting. Those who reported dieting were more likely to report healthiness (OR = 2·18, 95 % CI 1·11, 4·26) as an important factor when choosing food and that eating fruit and vegetables makes you better looking. No sex by dieting interaction was found.

In this cohort, while there was no difference in actual food consumption between dieters and non-dieters, there were significant differences in attitudes to food.

To assess the inter-method reliability of the Ovarian Cancer in Alberta (OVAL) survey developed to estimate adult vitamin D exposure from sun and diet for every tenth year, against the longer Geraldton Skin Cancer Prevention Survey (the assumed ‘gold standard’). We also estimated total vitamin D exposure using the OVAL survey.

A randomized crossover design to assess the inter-method reliability of sun exposure (OVAL v. Geraldton survey), using intra-class correlation and estimated total vitamin D exposure from sun and diet.

Calgary, Alberta, Canada.

Randomly selected women (n 90) aged 40–79 years.

The average lifetime sun exposure of 13 913 h (average 411 h/year) from the Geraldton survey was not significantly different from the 13 034 h (average 385 h/year) from the OVAL survey for periods with sufficient UV radiation to stimulate vitamin D production. The intra-class correlation coefficient for average lifetime sun exposure was 0·77 (95 % CI 0·69, 0·86); the annual average was 0·60 (95 % CI 0·47, 0·74). Estimated vitamin D from diet and supplements increased with age.

Our OVAL survey reliably estimated adult sun exposure relative to the Geraldton survey, suggesting that assessing sun exposure every tenth year is a reliable and efficient method for estimating sun contributions to lifetime vitamin D exposure.

The rate of type 2 diabetes mellitus among Inuit is 12·2 % in individuals over 50 years of age, similar to the Canadian prevalence. Given marked dietary transitions in the Arctic, we evaluated the dietary and other correlates of not previously diagnosed glucose intolerance, defined as type 2 diabetes mellitus, impaired fasting glucose or impaired glucose tolerance.

Cross-sectional analyses were limited to adults with a completed 2 h oral glucose tolerance test and without pre-existing diabetes. Anthropometric assessments, health and medication usage questionnaires and a 24 h dietary recall were administered.

Canadian International Polar Year Inuit Health Survey (2007–2008).

Inuit adults (n 777).

Glucose intolerance was associated with older age and adiposity. Percentage of energy from protein above the Acceptable Macronutrient Distribution Range of 35 %, compared with intake within the range, was associated with increased odds of glucose intolerance (OR=1·98; 95 % CI 1·09, 3·61) in multivariable analyses. Further, cholesterol intake in the highest three quartiles combined (median exposures of 207, 416 and 778 mg/d, respectively) compared with the lowest quartile (median intake of 81 mg/d) was associated with glucose intolerance (OR=2·15; 95 % CI 1·23, 3·78) in multivariable analyses. Past-day traditional food consumption was borderline protective of glucose intolerance (P=0·054) and high fibre intake was not significantly protective (P=0·08).

The results contribute to the existing literature on high protein and cholesterol intakes as they may relate to diabetes risk.

The association between high sugar-sweetened beverages (SSB) intake during pregnancy and offspring overweight/obesity has been reported only from Western countries. The objective of this study was to examine the association between SSB intake before and during pregnancy and offspring overweight/obesity among Japanese women.

Japanese prospective birth cohort study.

We analysed mother–offspring pairs who participated in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study from 2013 to 2017. SSB intake during pregnancy was evaluated using the FFQ and classified into three groups: none (0 g/d), medium (<195 g/d) and high (>195 g/d). Overweight or obesity at 1 year of age in offspring was defined as having a BMI Z-score greater than 2 sd, calculated based on the BMI reference data for Japanese children. Multiple logistic regression analyses were performed to examine the associations between SSB intake before and during pregnancy and offspring overweight/obesity, after adjusting for covariates.

Japanese mother–offspring pairs (n 7114).

The overweight/obesity rate of the offspring was 8·8 %. Pregnant women with a high intake of SSB in early to mid-pregnancy had a higher risk of overweight/obesity in their offspring compared with those who did not; the OR was 1·52 (95 % CI (1·09, 2·12)).

High SSB intake in early to mid-pregnancy was associated with an increased risk of offspring overweight/obesity at 1 year of age.

To present evidence on the burden and outcomes of co-morbidities among severely malnourished (SAM) children admitted to outpatient therapeutic programme (OTP) facilities in the conflict setting of Borno, Nigeria.

Retrospective medical chart review.

Facility-based study.

Children aged 6–59 months with SAM enrolled in OTP between June and November 2016 whose medical records were analysed. Only pneumonia and diarrhoea were examined due to data limitations. Stata software was used for descriptive, multivariate and survival analyses.

Records of 396 children with median age of 15 months were identified and analysed from the date of enrolment to exit from OTP. Mean length of stay in OTP was 61d, with co-infected SAM children having shorter stay (P=0·006). Of the total, 148 (37·4 %) had at least one co-morbidity (pneumonia or diarrhoea), of which thirty-nine (26·4 %) had both. Cumulative rate of mortality during follow-up time was 9·5 (95 % CI 6·0, 15·1) per 10 000 child-days; SAM children with co-morbidities were ten times more likely to die than those without (hazard ratio=10·2; 95 % CI 3·4, 31·0). In multivariable analysis, co-morbidity (P=0·01), oedema (P=0·003), dehydration (P=0·02) and weight on admission (P=0·01) were associated with mortality. Both recovery and defaulter rates (57·8 and 36·1 %, respectively) did not meet SPHERE standards.

Children with SAM and co-morbidities are less likely to survive, presenting a significant barrier in improving child survival. The findings call for integrated OTP models that incorporate clinical algorithms and ensure prompt referral for SAM children with co-morbidity.

Food literacy is the knowledge, skills and behaviours needed to meet food needs and determine intake and is conceptualised as eleven components under four domains of planning and managing, selecting, preparing, and eating. Previous measures of food literacy vary in their adherence to the conceptualisation and ability to capture totality of eating. This study aimed to determine items for inclusion and exclusion in a food literacy item pool and capture the general public’s interpretation of everyday food literacy practices.

Beginning with an item pool from previous studies, cognitive interviews were conducted using think-aloud and verbal probing methods. Data were first analysed for applicability, clarity, ambiguity and logic, then for emergent themes to ensure items captured the totality of the participant’s eating.

Australia

Australian residents over 18 years of age recruited via Facebook residential groups (n 20).

Of the original 116 items, 11 items had limited applicability; 13 items had unclear references; 32 items had lexical problems and 11 items had logical problems. In total, 29 items were deleted, 31 retained and 56 revised. Thematic analysis revealed participants limited their responses to consider only conventional practices such as grocery shopping, cooking and planned meals rather than the totality of their eating. An additional eighty-four items were developed to address eating out, incidental eating occasions and inconsistencies between participants assumed correct knowledge and that of public health guidelines. This resulted in a refined 171-item pool.

This study progresses the development towards a comprehensive, validated food literacy questionnaire.
