To understand who engages in home gardening and whether gardening is associated with fruit and vegetable intake and weight status.

A national cross-sectional survey.

Online survey panel in the USA.

Adults aged 18–75 years representing the US population with respect to gender, age, race/ethnicity, income and geographic region (n 3889).

Approximately 30 % of survey respondents reported growing edible plants in a home garden. Gardeners were more likely to be White or Asian, employed, have higher income, be married, have children in the household and live in rural areas. Gardeners were less likely to be obese and more likely to meet US dietary recommendations for fruit and vegetable consumption. In multivariable analyses, home gardens remained associated with fruit and vegetable intake and BMI when controlling for a range of socio-demographic characteristics and level of rurality.

The current study identifies who is gardening in the USA and provides useful information for public health efforts to increase gardening as a nutrition intervention. Future research should examine the benefits of home gardening and interventions to increase home gardening using more rigorous designs.

To evaluate the effects of Chile’s 2016 regulation restricting child-directed marketing of products high in energy, saturated fats, sodium and sugars on reducing children’s exposure to ‘high-in’ television food advertising.

Television use by pre-schoolers and adolescents was assessed via surveys in the months prior to implementation and a year after implementation. Hours and channels of television use were linked with the amount of high-in food advertising observed in corresponding content analyses of food advertisements (ads) from popular broadcast and cable channels to estimate changes in exposure to food ads from these channels.

Middle-lower and lower-income neighbourhoods in Santiago, Chile.

Pre-schoolers (n 879; mothers reporting) and adolescents (n 753; self-reporting).

Pre-schoolers’ and adolescents’ exposure to high-in food advertising in total decreased significantly by an average of 44 and 58 %, respectively. Exposure to high-in food advertising with child-directed appeals, such as cartoon characters, decreased by 35 and 52 % for pre-schoolers and adolescents, respectively. Decreases were more pronounced for children who viewed more television. Products high in sugars were the most prevalent among the high-in ads seen by children after implementation.

Following Chile’s 2016 child-directed marketing regulation, children’s exposure to high-in food advertising on popular broadcast and cable television decreased significantly but was not eliminated from their viewing. Later stages of the regulation are expected to eliminate the majority of children’s exposure to high-in food advertising from television.

Children are surrounded by ubiquitous forms of unhealthy food marketing at home and in schools. The US Department of Agriculture now restricts food and beverage marketing that does not meet Smart Snacks in School standards. School superintendents, as districts’ top administrators, play a critical role in ensuring marketing policies are implemented and adhered to; however, there is limited research involving this stakeholder group. The current study examined superintendents’ perspectives on food marketing in schools and the marketing provision in wellness policies, as well as experiences with the implementation of such policies.

Qualitative focus groups and follow-up interviews (with focus group participants) were conducted by trained researchers.

Focus groups occurred at The School Superintendents’ annual meeting; follow-up interviews were over the telephone.

Superintendents and assistant superintendents (n 39) from twenty-three states participated. Interviews were recorded and professionally transcribed; transcripts were team-coded in Atlas.ti using an iteratively revised coding guide to facilitate theme generation.

Despite common concerns that marketing to children was ‘insidious’, superintendents reported a wide range of food and beverage marketing policies. In addition, the main issue is fundraising – such as ‘restaurant nights’ – that results in marketing that occurs on- and off-campus and afterschool.

Discrepancies between perspectives and practices point to the challenges that superintendents face with budgetary constraints, as well as relationships with parent–teacher organisations. These findings provide important insights about superintendents’ perspectives and challenges, particularly for government and child health advocates supporting school districts, to implement these policies.

To gain insight in Dutch food bank recipients’ perception on the content of the food parcels, their dietary intake and how the parcels contribute to their overall dietary intake.

Eleven semi-structured focus group discussions were conducted. Focus group topics were based on Andersons food insecurity definition: the lack of availability of nutritionally adequate foods and the assured ability to acquire foods in socially acceptable ways. Data were coded and analysed with Atlas.ti 7.0 software, using the framework approach.

Seven food banks throughout the Netherlands.

A total of 44 Dutch food bank recipients.

Food bank recipients were not always satisfied with the amount, quality, variation and type of foods in the food parcel. For the participants who could afford to, supplementing the food parcel was reported as main reason for buying foods, and price was the most important aspect in selecting these foods. Participants were not satisfied with their dietary intake; they mainly reported not having enough to eat. The content of the food parcel importantly influenced participants’ overall dietary intake. Finally, participants reported struggling with their feelings of dissatisfaction, while also being grateful for the foods they receive.

This study suggests that, despite their best efforts, food banks are not meeting food bank recipients’ needs. Our results provide valuable directions for improving the content of the food parcels by increasing the quantity, quality and variation in the foods supplied. Whether this also improves the dietary intake of recipients needs to be determined.

To analyse the evolution of the soft drink industry’s use of self-regulation as a response to obesity and examine the motivations driving its development and the strategies used to promote it to policy makers.

We used a data set of industry documents published by the Australian Beverages Council (ABC) between 1998 and 2016. We analysed how the ABC voiced its political motivations about self-regulation and what internal nutrition policies it developed prior to its public launch of self-regulation. We also analysed two promotional strategies: funding research and writing policy submissions.

Australia.

Between 1998 and 2006, the ABC shifted from a defensive strategy that denied the role of its products in obesity to more conciliatory strategy that emphasised the role of the soft drink industry in solutions to obesity. The ABC deliberately timed the launch of its self-regulation to coincide with an international public health congress. Following its launch, the ABC funded research demonstrating the efficacy of self-regulation and wrote submissions to government nutrition policies arguing that further regulation was unnecessary.

The soft drink industry uses self-regulation to bolster its reputation and influence nutrition policy. Strategic timing plays a key role in the political influence of self-regulation.

Exposure to marketing for foods high in fat, salt or sugar (HFSS) reportedly influences consumption, nutritional knowledge and diet-related health among adolescents. In 2018/2019, the UK government held two consultations about introducing new restrictions on marketing for HFSS foods. To reinforce why these restrictions are needed, we examined adolescents’ awareness of marketing for HFSS foods, and the association between past month awareness and weekly HFSS food consumption.

Cross-sectional survey that measured past month awareness of ten marketing activities for HFSS foods (1 = everyday; 6 = not in last month). Frequencies were converted into aggregate past month awareness across marketing activities and grouped into three categories (low/medium/high). Consumption was self-reported for fifteen foods (twelve HFSS) (1 = few times/d; 9 = never). For each food, frequency was divided into higher/lower weekly consumption.

United Kingdom.

11–19-year-olds (n 3348).

Most adolescents (90·8 %) reported awareness of a least one marketing activity for HFSS foods, and at least half reported seeing ≥70 instances in the past month. Television, social media and price offers were the marketing activities most frequently reported. Awareness was associated with higher weekly consumption for ten of the twelve HFSS foods. For example, those reporting medium marketing awareness were 1·5 times more likely to report higher weekly consumption of cakes/biscuits compared with those reporting low awareness (AOR = 1·51, P = 0·012). The likelihood of higher weekly HFSS food consumption increased relative to the level of marketing awareness.

Assuming there is a causal relationship between marketing awareness and consumption, the restrictions proposed by the UK government are likely to help reduce HFSS consumption.

To compare exposure to household food insufficiency and the relationship between household food insufficiency and both health status and emergency healthcare utilisation among children with and without special healthcare needs (SHCN).

Analysing pooled data from the 2016–2017 iterations of the National Survey of Children’s Health, we conducted multivariate logistic regressions on household food insufficiency, health status and emergency healthcare utilisation. We assessed interactions between household food insufficiency and children’s SHCN status in our models of health status and utilisation.

United States.

Parents of a nationally representative sample of non-institutionalised children (aged 0–17 years).

Children with SHCN were more likely to experience household food insufficiency (70 v. 56 %), non-excellent health status (67 v. 28 %) and emergency healthcare utilisation (32 v. 18 %) than other children. Household food insufficiency was associated with 37 % (children with SHCN) and 19 % (children without SHCN) reductions in the likelihood of having excellent health. Household food insufficiency was associated with a roughly equal (16–19 %) increase in the likelihood of emergency department utilisation across groups.

Compared with other children, children with SHCN have an elevated risk of exposure to household food insufficiency and experiencing greater reductions in health status when exposed.

To compare the nutritional quality of children’s combination meals offered at large US chain restaurants characterised by three versions – default (advertised), minimum (lower-energy) and maximum (higher-energy).

We identified default children’s meals (n 92) from online restaurant menus, then constructed minimum and maximum versions using realistic additions, substitutions and/or portion size changes for existing menu items. Nutrition data were obtained from the MenuStat database. Bootstrapped linear models assessed nutrition differences between meal versions and the extent to which meal components (main dish, side dish, beverage) drove differences across versions. For each version, we examined the proportion of meals meeting the Guidelines for Responsible Food Marketing to Children.

Twenty-six fast-food and fast-casual restaurants, in 2017.

None.

Nutrient values differed significantly across meal versions for energy content (default 2443 kJ (584 kcal), minimum 1674 kJ (400 kcal), maximum 3314 kJ (792 kcal)), total fat (23, 17, 33 g), saturated fat (8, 6, 11 g), Na (1046, 915, 1287 mg) and sugar (35, 14, 51 g). The substitution of lower-energy beverages resulted in the greatest reduction in energy content (default to minimum, −418 kJ (−100 kcal)) and sugar (−20 g); choosing lower-energy side dishes resulted in the greatest reduction in total fat (default to minimum, −4 g), saturated fat (−1·1 g) and Na (−69 mg). Only 3 % of meals met guidelines for all nutrients.

Realistic modifications to children’s combination meals using existing menu options can significantly alter a meal’s nutrient composition. Promoting lower-energy items as the default option, especially for beverages and side dishes, has a potential to reduce fat, saturated fat and/or sugar in children’s meals.

The Ringing Up About Breastfeeding earlY (RUBY) randomised controlled trial (RCT) found that a telephone-based peer volunteer support intervention increased breast-feeding duration in a setting with high breast-feeding initiation. This sub-study of the RUBY RCT describes the motivation, preparation and experiences of volunteers who provided the peer support intervention.

An online survey was completed by 154 (67 %) volunteers after ceasing volunteering.

Volunteers provided peer support to primiparous women (n 574) who birthed at one of three public hospitals in Melbourne, Australia, between February 2013 and December 2015.

Volunteers (n 230) had themselves breastfed for at least 6 months and received 4 h of training for the role.

The median number of mothers supported was two (range 1–11), and two-thirds of respondents supported at least one mother for 6 months. Volunteers were motivated by a strong desire to support new mothers to establish and continue breast-feeding. Most (93 %) considered the training session adequate. The majority (60 %) reported following the call schedule ‘most of the time’, but many commented that ‘it depends on the mother’. Overall, 84 % of volunteers were satisfied with the role and reported that the experience was enjoyable (85 %) and worthwhile (90 %). Volunteers agreed that telephone support for breast-feeding was valued by women (88 %) and that the programme would be effective in helping women to breastfeed (93 %).

These findings are important for those developing similar peer support programmes in which recruiting volunteers and developing training requirements are an integral and recurrent part of volunteer management.

The aim of the current study was to evaluate the effect on frequency, variety and amount of vegetables served and staff’s food-related practices in the multicomponent BRA intervention.

Cluster randomised controlled trial, conducted between Spring 2015 and Spring 2016. For allocation of the kindergartens, a stratified block randomisation was used. Data were collected in three ways: (i) a questionnaire for pedagogical leaders assessing the variety and frequency of vegetables served, including staff’s food-related practices assumed to be related to vegetable intake; (ii) a questionnaire for kindergarten assistants assessing staff’s food-related practices; (iii) a 5-d weighted vegetable diary assessing amount of vegetables served in a department.

The target group for this study was public and private kindergartens in the counties of Vestfold and Buskerud, Norway.

A total of seventy-three kindergartens participated.

At follow-up I, the amount of vegetables served increased by approximately 20 g per person per day (P = 0·002), and the variety in served vegetables increased by one-and-a-half kind per month (P = 0·014) in the intervention group compared to the control group. No effects on the frequency of vegetables served or on staff’s food-related practices were found.

The BRA intervention was successful in increasing the amount and variety of vegetables served within intervention kindergartens. Further research is needed to understand the mechanisms that can affect the staff’s food-related practices.

We aimed to investigate the associations between school-level characteristics and obesity among Chinese primary school children with consideration of individual-level characteristics.

This cross-sectional study was conducted in 2015/2016. School-level characteristics were assessed using an interviewer-administered school questionnaire, and a ‘school-based obesity prevention index’ was further developed. Individual-level characteristics were collected by self-administered questionnaires. Objectively measured height and weight of students were collected, and obesity status was classified according to the International Obesity Task Force criteria for Asian children. Generalised linear mixed models were used to estimate the associations among the school- and individual-level characteristics and obesity of students.

Thirty-seven primary schools from an urban and a rural district of Beijing, China.

School staffs, 2201 students and their parents.

The school-based obesity prevention index involved the number of health professionals, availability of students’ health records, monitoring students’ nutrition status, frequency of health education activities, reporting achievements of obesity prevention activities to parents, duration of physical activity during school time and availability of playground equipment. The prevalence of obesity was lower in schools with the higher index value compared with that in schools with the lower index value (OR 0·56; 95 % CI 0·40, 0·79). Some individual-level characteristics were negatively associated with childhood obesity: liking sports, duration of screen time ≤2 h/d, perceived lower eating speed, parental non-overweight/obesity.

Irrespective of individual-level characteristics, the specific school-level characteristics had a cumulative effect on obesity among Chinese primary school children. Further school-based obesity intervention should consider these characteristics simultaneously.

To assess, from a systems perspective, how climate vulnerability and socio-economic and political differences at the municipal and state levels explain food insecurity in Mexico.

Using a cross-sectional design with official secondary data, we estimated three-level multinomial hierarchical linear models.

The study setting is Mexico’s states and municipalities in 2014.

Heads of households in a representative sample of the general population.

At the municipal level, vulnerability to climate disasters and a poverty index were significant predictors of food insecurity after adjusting for household-level variables. At the state level, gross domestic product and the number of nutrition programmes helped explain different levels of food insecurity but change in political party did not. Predictors varied in strength and significance according to the level of food insecurity.

Findings evidence that, beyond food assistance programmes and household characteristics, multiple variables operating at different levels – like climate vulnerability and poverty – contribute to explain the degree of food insecurity. Food security governance is a well-suited multisectoral approach to address the complex challenge of hunger and access to a nutritious diet.

Our study analysed evolving regional commitments on food policy in the Pacific. Our aim was to understand regional priorities and the context of policy development, to identify opportunities for progress.

We analysed documentation from a decade of regional meetings in order to map regional policy commitments relevant to healthy diets. We focused on agriculture, education, finance, health, and trade sectors, and Heads of State forums. Drawing on relevant political science methodologies, we looked at how these sectors ‘frame’ the drivers of and solutions to non-communicable diseases (NCD), their policy priorities, and identified areas of coherence and tension.

The Pacific has among the highest rates of non-communicable diseases in the world, but also boasts an innovative and proactive response. Heads of State have declared NCD a ‘crisis’ and countries have committed to specific prevention activities set out in a regional ‘Roadmap’. Yet, diet-related NCD risk-factors remain stubbornly high and many countries face challenges in establishing a healthy food environment.

Policies to improve food environments and prevent NCD are a stated priority across regional policy forums, with clear agreement on the need for a multi-sectoral response. However, we identified challenges in sustaining these priorities as political attention fluctuated. We found examples of inconsistencies and tension in sectoral responses to the NCD epidemic that may restrict implementation of the multi-sectoral action.

Understanding the priorities and positions underpinning sectoral responses can help drive a more coherent NCD response, and lessons from the Pacific are relevant to public health nutrition policy and practice globally.

There are concerns that some non-profit organisations, financed by the food industry, promote industry positions in research and policy materials. Using Freedom of Information (FOI) requests, we test the proposition that the International Life Sciences Institute (ILSI), one prominent non-for profit in international health and nutrition research, promotes industry positions.

U.S. Right to Know filed five FOI from 2015 to 2018 covering communications with researchers at four US institutions: Texas A&M, University of Illinois, University of Colorado and North Carolina State University. It received 15 078 pages, which were uploaded to the University of California San Francisco’s Industry Documents Library. We searched the Library exploring it thematically for instances of: (1) funding research activity that supports industry interests; (2) publishing and promoting industry-sponsored positions or literature; (3) disseminating favourable material to decision makers and the public and (4) suppressing views that do not support industry.

Available emails confirmed that ILSI’s funding by corporate entities leads to industry influence over some of ILSI activities. Emails reveal a pattern of activity in which ILSI sought to exploit the credibility of scientists and academics to bolster industry positions and promote industry-devised content in its meetings, journal and other activities. ILSI also actively seeks to marginalise unfavourable positions.

We conclude that undue influence of industry through third-party entities like ILSI requires enhanced management of conflicts of interest by researchers. We call for ILSI to be recognised as a private sector entity rather than an independent scientific non-profit, to allow for more appropriate appraisal of its outputs and those it funds.
