To assess corporate electoral campaign contributions from industries related to sugary drinks production and the characteristics of the elected officials financed by the sector.

Cross-sectional analysis of electoral campaign contributions from corporations related to sugary drinks production (sugary drink industries and sugary drink input industries) to candidates to the Chamber of Deputies, Brazil.

Elections to the 55th Congress (2015–2019), held in October 2014.

Candidates to the Chamber of Deputies, Brazil.

Forty-nine companies or corporate groups that produce sugary drinks and fifty-two corporations that produce inputs for sugary drinks manufacturing contributed to electoral campaigns of candidates in the 2014 Election. Contributions from this industry sector represented 7·3 % of all corporate contributions and helped finance 11·7 % of the candidates and 46·2 % of the elected officials. The transnationals Ambev and Coca-Cola were the first and second biggest donors, respectively. Revenues mediated by political parties, from sugary drink industries and from corporate members of some industry associations (Abir, Unica and CitrusBR), were more prevalent. Among elected officials, a significant association was found between being financed by the sector and representing the south-east region, having higher education level and referring themselves as being professional politicians. In the multivariate model, financed candidates were 27 % more likely to be elected.

Corporations related to sugary drinks production have contributed to the electoral campaigns of almost half of the Federal Deputies in Brazil in 2014. This possibly facilitates access to decision-makers and could help buy influence on legislative proposals, including health-related food policies.

To identify the efficacy of group-based nutrition interventions to increase healthy eating, reduce nutrition risk, improve nutritional status and improve physical mobility among community-dwelling older adults.

Systematic review. Electronic databases MEDLINE, CINAHL, EMBASE, PsycINFO and Sociological Abstracts were searched on July 15, 2020 for studies published in English since January 2010. Study selection, critical appraisal (using the Joanna Briggs Institute’s tools) and data extraction were performed in duplicate by two independent reviewers.

Nutrition interventions delivered to groups in community-based settings were eligible. Studies delivered in acute or long-term care settings were excluded.

Community-dwelling older adults aged 55+ years. Studies targeting specific disease populations or promoting weight loss were excluded.

Thirty-one experimental and quasi-experimental studies with generally unclear to high risk of bias were included. Interventions included nutrition education with behaviour change techniques (BCT) (e.g. goal setting, interactive cooking demonstrations) (n 21), didactic nutrition education (n 4), interactive nutrition education (n 2), food access (n 2) and nutrition education with BCT and food access (n 2). Group-based nutrition education with BCT demonstrated the most promise in improving food and fluid intake, nutritional status and healthy eating knowledge compared with baseline or control. The impact on mobility outcomes was unclear.

Group-based nutrition education with BCT demonstrated the most promise for improving healthy eating among community-dwelling older adults. Our findings should be interpreted with caution related to generally low certainty, unclear to high risk of bias and high heterogeneity across interventions and outcomes. Higher quality research in group-based nutrition education for older adults is needed.

Dietary recommendations (DR) in the USA may be inadequate at improving diets in racial/ethnic minority communities and may require redesign of the systems driving their development over the long term. Meanwhile, cultural adaptation of evidence-based DR may be an important strategy for mitigating nutrition disparities, but less is known about the adaptability of these recommendations to meet the needs of diverse groups. We examined the content and origin of major DRs – aspects that provide context on their potential universality across populations and evaluated their potential for cultural adaptation.

Case studies of Dietary Approaches to Stop Hypertension (DASH), the Mediterranean diet (MD), the EAT-Lancet diet (EAT) and the NOVA classification system.

United States.

Racial/ethnic minority populations.

Current DR differ in their origin/evolution but are similar in their reductionist emphasis on physical health. DASH has been successfully adapted for some cultures but may be challenged by the need for intensive resources; MD may be more beneficial if applied as part of a broader set of food procurement/preparation practices than as just diet alone; EAT-Lancet adaptation may not honor existing country-specific practices that are already beneficial to human and environmental health (e.g. traditional/plant-based diets); evidence for cultural adaptation is limited with NOVA, but classification of levels of food processing has potential for widespread application.

For DR to equitably support diverse populations, they must move beyond a Eurocentric or ‘general population’ framing, be more inclusive of cultural differences and honour social practices to improve diet and reduce disparities.

Higher neighbourhood walkability would be expected to contribute to better health, but the relevant evidence is inconsistent. This may be because residents’ dietary attributes, which vary with socio-economic status (SES) and influence their health, can be related to walkability. We examined associations of walkability with dietary attributes and potential effect modification by area-level SES.

The exposure variable of this cross-sectional study was neighbourhood walkability, calculated using residential density, intersection density and destination density within 1-km street-network buffer around each participant’s residence. The outcome variables were dietary patterns (Western, prudent and mixed) and total dietary energy intake, derived from a FFQ. Main and interaction effects with area-level SES were estimated using two-level linear regression models.

Participants were from all states and territories in Australia.

The analytical sample included 3590 participants (54 % women, age range 34 to 86).

Walkability was not associated with dietary attributes in the whole sample. However, we found interaction effects of walkability and area-level SES on Western diet scores (P < 0·001) and total energy intake (P = 0·012). In low SES areas, higher walkability was associated with higher Western dietary patterns (P = 0·062) and higher total energy intake (P = 0·066). In high SES areas, higher walkability was associated with lower Western diet scores (P = 0·021) and lower total energy intake (P = 0·058).

Higher walkability may not be necessarily conducive to better health in socio-economically disadvantaged areas. Public health initiatives to enhance neighbourhood walkability need to consider food environments and socio-economic contexts.

To investigate the effects of providing a daily healthy school snack on children’s nutritional, social and educational outcomes and explore stakeholders’ perceptions of an emergency school feeding programme (SFP).

Convergence triangulation mixed-methods study design. Associations were examined between receiving the school feeding intervention and children’s outcomes using multivariable regression models. Quantitative data were complemented with interviews and focus group discussions with parents and staff.

In vulnerable communities in Lebanon, the World Food Programme has implemented an emergency SFP targeting Lebanese (attending morning sessions) and Syrian refugee children (attending afternoon sessions) in public schools.

Children from ten intervention schools (morning n 403; afternoon n 379) and ten matched control schools (morning n 399; afternoon n 401), as well as twenty-nine parents and twenty-two school staff members.

Diet diversity was higher in intervention schools as compared with control with a significantly higher consumption of dairy products, nuts and fruit in both sessions. Child-reported food insecurity experience was lower in children attending the afternoon session of intervention v. control schools. The SFP intervention was associated with higher school engagement and sense of school community in the morning session only. While the SFP was significantly associated with higher attendance for children in afternoon sessions only, it was significantly associated with school retention of children in both sessions.

A daily healthy snack potentially acts as an incentive to improve children’s nutritional outcomes, school engagement, sense of belonging, equality between students and improvement in children’s attendance and retention in public schools.

To evaluate the feasibility and acceptability of a mobile-based brief intervention (BI), generate preliminary estimates of the impact of the BI and fine-tune the procedures for a definitive randomised controlled trial.

Parallel three-arm single-blind individually randomised controlled pilot trial. Eligible and consenting participants were randomised to receive mobile-based BI, face-to-face BI and information leaflet.

Educational institutions, workplaces and primary care centres.

Adult hazardous drinkers.

Seventy-four participants were randomised into the three trial arms; forty-eight (64·9 %) completed outcome evaluation. There were no significant differences between the three arms on change in any of the drinking outcomes. There were however in two-way comparisons. Face-to-face BI and mobile BI were superior to active control for percent days heavy drinking at follow-up, and mobile BI was superior to active control for mean grams ethanol consumed per week at follow-up.

The encouraging findings about feasibility and preliminary impact warrant a definitive trial of our intervention and if found to be effective, our intervention could be a potentially scalable first-line response to hazardous drinking in low-resource settings.

To assess the cost-effectiveness of prophylactic Zn supplementation for preventing diarrhoea in young children in Tanzania.

Cost-effectiveness analysis using decision-analytic modelling. Cost-effectiveness ratios were calculated as the incremental cost (2019 USD) per disability-adjusted life year (DALY) averted, from a societal perspective, and with a 3 % discount rate applied to future outcomes. Sensitivity analyses were performed to test the robustness of results to alternative assumptions.

Tanzania.

A hypothetical cohort of 10 000 children aged 6 weeks to 18 months.

The intervention costs of Zn supplementation were estimated as $109 800 (95 % uncertainty interval: 61 716, 171 507). Zn supplementation was estimated to avert 2200 (776, 3737) diarrhoeal episodes, 14 080 (4692, 25 839) sick days, 1584 (522, 2927) outpatient visits, 561 (160–1189) inpatient bed days, 0·51 (0·15, 1·03) deaths and 19·3 (6·1, 37·5) DALY (discounted at 3 % per year). Zn supplementation reduced diarrhoea care costs by $12, 887 (4089, 25 058). The incremental cost per DALY averted was $4950 (1678, 17 933). Incremental cost-effectiveness ratios (ICER) estimated from a health system perspective were similar to the results from the societal perspective. ICER were substantially lower (more favourable) when future outcomes were not discounted, but all ICER were above contemporary thresholds for cost-effectiveness in this setting.

Prophylactic Zn reduced diarrhoea incidence and associated healthcare utilisation; however, it did not appear to be cost-effective for prevention of childhood diarrhoea in the scenario examined in this study. Reducing intervention costs, or identifying high risk groups for intervention targeting, may be needed to improve cost-effectiveness in this setting.

This study aimed to apply the newly developed Chile Adjusted Model (CAM) nutrient profiling model (NPM) to the food supply in South Africa (SA) and compare its performance against existing NPM as an indication of suitability for use to underpin food policies targeted at discouraging consumption of products high in nutrients associated with poor health.

Cross-sectional analysis of the SA-packaged food supply comparing the CAM to three other NPM: SA Health and Nutrition Claims (SA HNC), Chilean Warning Octagon (CWO) 2019, and Pan-American Health Organisation (PAHO) NPM.

The SA-packaged food supply based on products stocked by supermarkets in Cape Town, SA.

Packaged foods and beverages (n 6474) available in 2018 were analysed.

Forty-nine per cent of products contained excessive amounts of nutrients of concern (considered non-compliant) according to the criteria of all four models. Only 10·9 % of products were not excessive in any nutrients of concern (considered compliant) according to all NPM evaluated. The CAM had an overall non-compliance level of 73·2 % and was comparable to the CWO 2019 for foods (71·2 % and 71·1 %, respectively). The CAM was the strictest NPM for beverages (80·4 %) due to the criteria of non-sugar sweeteners and free sugars. The SA HNC was the most lenient with non-compliance at 52·9 %. This was largely due to the inclusion of nutrients to encourage, which is a criterion for this NPM.

For the purpose of discouraging products high in nutrients associated with poor health in SA, the CAM is a suitable NPM.

Drinks containing added sugar and/or non-nutritive sweeteners are not recommended for children under 6 years. Yet, most young children consume these products. The current study examined factors associated with caregivers’ provision of sweetened drinks to their young child.

Caregivers reported frequency of providing sweetened fruit-flavoured drinks (fruit drinks and flavoured water) and unsweetened juices (100 % juice and juice/water blends) to their 1- to 5-year-old child in the past month and perceived importance of product attributes (healthfulness, product claims and other characteristics), other drinks provided, reading the nutrition facts panel and socio-demographic characteristics. A partial proportional odds model measured the relationship between these factors and frequency of providing sweetened fruit-flavoured drinks.

Online cross-sectional survey.

U.S. caregivers (n 1763) with a young child (ages 1–5).

The majority (74 %) of caregivers provided sweetened fruit-flavoured drinks to their child in the past month; 26 % provided them daily. Provision frequency was positively associated with some drink attributes, including perceived healthfulness, vitamin C claims and box/pouch packaging; child requests and serving other sweetened drinks and juice/water blends. Provision frequency was negatively associated with perceived importance of ‘no/less sugar’ and ‘all natural’ claims. Reading nutrition facts panels, serving water to their child and child’s age were not significant.

Misunderstanding of product healthfulness and other marketing attributes contribute to frequent provision of sweetened drinks to young children. Public health efforts to address common misperceptions, including counter marketing, may raise awareness among caregivers about the harms of providing sweetened drinks to young children.

To explore whether individuals who consume higher amounts of ultra-processed food (UPF) have more adverse mental health symptoms.

Using a cross-sectional design, we measured the consumption of UPF as a percentage of total energy intake in kilo-calories using the NOVA food classification system. We explored whether individuals who consume higher amounts of UPF were more likely to report mild depression, more mentally unhealthy days and more anxious days per month using multivariable analyses adjusting for potential confounding variables.

Representative sample from the United States National Health and Nutrition Examination Survey between 2007 and 2012.

10 359 adults aged 18+ without a history of cocaine, methamphetamine or heroin use.

After adjusting for covariates, individuals with the highest level of UPF consumption were significantly more likely to report at least mild depression (OR: 1·81; 95 % CI1·09, 3·02), more mentally unhealthy (risk ratio (RR): 1·22; 95 % CI 1·18, 1·25) and more anxious days per month (RR: 1·19; 95 % CI 1·16, 1·23). They were also significantly less likely to report zero mentally unhealthy (OR: 0·60; 95 % CI 0·41, 0·88) or anxious days (OR: 0·65; 95 % CI 0·47, 0·90).

Individuals reporting higher intakes of UPF were significantly more likely to report mild depression, more mentally unhealthy and more anxious days and less likely to report zero mentally unhealthy or anxious days. These data add important information to a growing body of evidence concerning the potential adverse effects of UPF consumption on mental health.

To systematically assess Germany’s nutrition policies, to benchmark them against international best practices and to identify priority policy actions to improve population-level nutrition in Germany.

We applied the Food Environment Policy Index (Food-EPI), a methodological framework developed by the International Network for Food and Obesity/non-communicable Diseases Research, Monitoring and Action Support (INFORMAS) network. Qualitative content analysis of laws, directives and other documents formed the basis of a multistaged, structured consultation process.

Germany.

The expert consultation process included fifty-five experts from academia, public administration and civil society.

Germany lags behind international best practices in several key policy areas. For eighteen policy indicators, the degree of implementation compared with international best practices was rated as very low, for twenty-one as low, for eight as intermediate and for none as high. In particular, indicators on food taxation, regulation of food marketing as well as retail and food service sector policies were rated as very low to low. Identified priority actions included the binding implementation of nutrition standards for schools and kindergartens, a reform of the value added tax on foods and beverages, a sugar-sweetened beverage tax and stricter regulation of food marketing directed at children.

The results show that Germany makes insufficient use of the potential of evidence-informed health-promoting nutrition policies. Adopting international best practices in key policy areas could help to reduce the burden of nutrition-related chronic disease and related inequalities in nutrition and health in Germany. Implementation of relevant policies requires political leadership, a broad societal dialogue and evidence-informed advocacy by civil society, including the scientific community.

To estimate the prevalence and socio-economic inequalities in adequate consumption of fruits and vegetables in Peru between 2014 and 2019.

Analytical cross-sectional study. The outcome variable was adequate consumption of fruits and vegetables, defined as the consumption of five or more servings of fruits and vegetables per d (yes/no). We used concentration curves and Erreygers concentration index to describe socio-economic inequalities and a microeconometric approach to determine the contribution of each variable to inequality.

Peru.

Data from Peruvians aged 18 years or older collected by the Demographic and Family Health Survey.

The prevalence of adequate fruit and vegetable consumption did not change between 2014 (10·7 %; 95 % CI (10·0, 11·4)) and 2019 (11 %; 95 % CI (10·4, 11·7)). We found socio-economic inequalities in the adequate consumption of fruits and vegetables, with wealthier individuals having a higher prevalence of adequate consumption compared to poorer individuals in 2014 (19·2 % v. 3·5 %) and 2019 (18·6 % v. 4·7 %). The decomposition analysis found that education, urban areas and being wealthy were the main factors associated with socio-economic inequality in adequate fruit and vegetable consumption, being structural problems of society.

Despite the current regulations on healthy eating in Peru, adequate consumption of fruits and vegetables remains low, and there are socio-economic inequalities between the poorest and wealthiest individuals. Our findings suggest that more efforts are needed to increase the intake and assess the disparities in adequate fruit and vegetable consumption.

To quantify the extent of food and beverage advertising on bus shelters in a deprived area of the UK, to identify the healthfulness of advertised products, and any differences by level of deprivation. The study also sought to assess the creative strategies used and extent of appeal to young people.

Images of bus shelter advertisements were collected via in person photography (in 2019) and Google Street View (photos recorded in 2018). Food and beverage advertisements were grouped into one of seventeen food categories and classified as healthy/less healthy using the UK Nutrient Profile Model. The deprivation level of the advertisement location was identified using the UK Index of Multiple Deprivation.

Middlesbrough and Redcar and Cleveland in South Teesside.

N/A

Eight hundred and thirty-two advertisements were identified, almost half (48·9 %) of which were for foods or beverages. Of food and non-alcoholic beverage adverts, 35·1 % were less healthy. Most food advertisements (98·9 %) used at least one of the persuasive creative strategies. Food advertisements were found to be of appeal to children under 18 years of age (71·9 %). No differences in healthiness of advertised foods were found by level of deprivation.

Food advertising is extensive on bus shelters in parts of the UK, and a substantial proportion of this advertising is classified as less healthy and would not be permitted to be advertised around television programming for children. Bus shelter advertising should be considered part of the UK policy deliberations around restricting less healthy food marketing exposure.

The objective of the current study was to evaluate the impact of the Market to MyPlate (M2MP) program on participants’ reported farmers’ market (FM) attitudes and shopping behaviours, frequency of serving vegetables to their families, food resource management behaviours and food security. A secondary objective was to identify facilitators and barriers to shopping at FM and food waste reduction techniques used by low-income families.

The current study used a mixed methods evaluation embedded within a cluster randomised trial of the M2MP intervention.

The 7-week M2MP program was delivered at Extension offices and community centres in central Illinois.

Participants included 120 adults and their families. Class cohorts were randomly assigned to one of three treatment groups: (1) nutrition education and cooking classes with produce allocations (PAE, n 39); (2) nutrition education and cooking classes only (EO, n 36) or (3) control group (n 45).

Compared with control participants, PAE participants were significantly more likely to report shopping at FM (P = 0·029) and reported serving more vegetables to their families (P = 0·010) (EO participants did not differ from the control group on any outcomes). There were no differences between conditions in survey-based measures of food security or food resource management behaviours. Interview results describe facilitators and barriers to shopping at FM and a variety of food waste reduction techniques (including food placement and food resource management).

These findings suggest that fresh produce provision coupled with nutrition and culinary education can positively impact shopping and dietary behaviours.

The rapid growth in web-based grocery food purchasing has outpaced federal regulatory attention to the online provision of nutrition and allergen information historically required on food product labels. We sought to characterise the extent and variability that online retailers disclose required and regulated information and identify the legal authorities for the federal government to require online food retailers to disclose such information.

We performed a limited scan of ten products across nine national online retailers and conducted legal research using LexisNexis to analyse federal regulatory agencies’ authorities.

USA.

N/A.

The scan of products revealed that required information (Nutrition Facts Panels, ingredient lists, common food allergens and per cent juice for fruit drinks) was present, conspicuous and legible for an average of only 36·5 % of the products surveyed, ranging from 11·4 % for potential allergens to 54·2 % for ingredients lists. More commonly, voluntary nutrition-related claims were prominently and conspicuously displayed (63·5 % across retailers and products). Our legal examination found that the Food and Drug Administration, Federal Trade Commission and United States Department of Agriculture have existing regulatory authority over labelling, online sales and advertising, and Supplemental Nutrition Assistance Programme retailers that can be utilised to address deficiencies in the provision of required information in the online food retail environment.

Information regularly provided to consumers in conventional settings is not being uniformly provided online. Congress or the federal agencies can require online food retailers disclose required nutrition and allergen information to support health, nutrition, equity and informed consumer decision-making.

To test the efficacy of three nutrition education strategies on the intake of different vegetables in preschool children.

This is an experimental study conducted in four Portuguese preschools. The intervention consisted of 20-min educational sessions, once a week, for 5 weeks, with one of the following randomised educational strategies: Portuguese Food Wheel Guide (control), digital game, storybook, storybook and reward (stickers). All groups had repeated exposure to vegetables in all sessions. A pre- and post-test were conducted to determine vegetable intake, and a 6-month follow-up was realised.

Preschools of Leiria district, Portugal.

A sample of 162 children aged 3 to 6 years. All eligible children attending the preschools were invited to participate.

All interventions tested were effective in increasing vegetable consumption both in the short and medium term, without statistically significant differences, compared to the control group. Stickers were more effective in the short term than in the medium term.

The nutritional education strategies associated with repeated exposure tested in this study were effective in promoting vegetable consumption in preschool children. The use of stickers may be a valid strategy to promote the consumption of vegetables less recognised by children.

This scoping review sought to describe the policy actions that urban local governments globally have implemented to facilitate healthy and environmentally sustainable diet-related practices.

Urban local government authorities.

Five databases were searched to identify publications which cited policies being implemented by local governments within the 199 signatory cities of the Milan Urban Food Policy Pact (MUFPP) that targeted at least one healthy and sustainable diet-related practice. Grey literature was then searched to retrieve associated policy documentation. Data from both sources were charted against the MUFPP’s monitoring framework to analyse the policy actions included in each overarching policy.

From 2624 screened peer-reviewed studies, 27 met inclusion criteria and cited 36 relevant policies amongst signatory cities to the MUFPP. Most were from high income countries (n 29; 81 %), considered health (n 31; 86 %), equity (n 29; 81 %) and the broader food system beyond dietary consumption (n 34; 94 %). Of the 66 policy actions described, the most common involved food procurement within public facilities (n 16; 44 %) and establishing guidelines for school-feeding programs (n 12; 33 %).

This review has demonstrated that urban local government authorities are implementing policies that consider multiple phases of the food supply chain to facilitate population-wide uptake of healthy and sustainable diet-related practices. Opportunities exist for local governments to leverage the dual benefits to human and planetary health of policy actions, such as those which discourage the overconsumption of food including less meat consumption and the regulation of ultra-processed foods.

To evaluate the impact of a multi-level, multi-component (MLMC) adult obesity intervention on beverage intake in Native American adults living in five geographically and culturally diverse tribal communities.

A 14-month, community-randomised, MLMC design was utilised, with three communities randomised to Intervention and two communities randomised to Comparison. FFQ were administered pre- and post-interventions, and difference-in-differences (DiD) analysis was used to assess intervention impact on beverage intake.

The intervention took place within food stores, worksites, schools and selected media outlets located in the five communities. Key activities included working with store owners to stock healthy beverages, display and dispersal of educational materials, support of policies that discouraged unhealthy beverage consumption at worksites and schools and taste tests.

Data were collected from 422 respondents between the ages of 18 and 75 living in the five communities pre-intervention; of those, 299 completed post-intervention surveys. Only respondents completing both pre- and post-intervention surveys were included in the current analysis.

The DiD for daily servings of regular, sugar-sweetened soda from pre- to post-intervention was significant, indicating a significant decrease in Intervention communities (P < 0·05). No other changes to beverage intake were observed.

Large, MLMC obesity interventions can successfully reduce the intake of regular, sugar-sweetened soda in Native American adults. This is important within modern food environments where sugar-sweetened beverages are a primary source of added sugars in Native American diets.
