The present study describes the energy content of primary-school children’s lunchboxes and the proportion of lunchbox foods considered discretionary. Subgroup analyses by sex, socio-economic status, age and weight status were undertaken.

A cross-sectional study was conducted. Mean kilojoule content, number of items and categorisation of foods and drinks in lunchboxes as ‘everyday’ (healthy) or discretionary (sometimes) foods were assessed via a valid and reliable lunchbox observational audit.

Twelve Catholic primary schools (Kindergarten–Grade 6) located in the Hunter region of New South Wales, Australia.

Kindergarten to Grade 6 primary-school students.

In total, 2143 children (57 %) had parental consent to have their lunchboxes observed. School lunchboxes contained a mean of 2748 kJ, of which 61·2 % of energy was from foods consistent with the Australian Dietary Guidelines and 38·8 % of energy was discretionary foods. The proportion of lunchboxes containing only healthy foods was 12 %. Children in Kindergarten–Grade 2 packed more servings of ‘everyday’ foods (3·32 v. 2·98, P < 0·01) compared with children in Grades 3–6. Children in Grades 3–6 had a higher percentage of energy from discretionary foods (39·1 v. 33·8 %, P < 0·01) compared with children in Kindergarten–Grade 2 and children from the most socio-economically disadvantaged areas had significantly higher total kilojoules in the school lunchbox compared with the least disadvantaged students (2842 v. 2544 kJ, P = 0·03).

Foods packed within school lunchboxes may contribute to energy imbalance. The development of school policies and population-based strategies to support parents overcome barriers to packing healthy lunchboxes are warranted.

To investigate food democracy and health disparities in the New York City (NYC) trans fat policy process.

Texts from semi-structured interviews, public testimony and comments on the policy were analysed using categorization and thematic coding. A priori content analysis for themes of food democracy was followed by open, axial and selective coding for sub-themes on health disparities. Data and method triangulation and respondent validation were used to establish data dependability, trustworthiness and representativeness.

NYC.

Interviews from a purposive, snowballed sample of thirty-three participants included restaurateurs, scientists, health and consumer advocates, consumers and policy makers. Additionally, 261 pages of transcript from public testimony of fifty-three participants and a purposive sample of public comments on the policy from a pool of 2157 were analysed.

Principles of food democracy involving inclusive citizenship, access to information, collaborative participation and focus on collective good were well represented in the data. Additionally, sub-themes linked to health disparities included: government responsibility for fairer access to healthier foods; recognition that people made choices based on circumstances; concern for vulnerable groups; and outrage with a food industry viewed as unconcerned for public health.

Principles of food democracy present in the successful process of adoption of the 2006 NYC trans fat policy addressed nutrition-related health. Food democracy is a contemporary food system and policy approach with potential for public health benefits in reducing nutrition-related health disparities.

To describe relationships among baseline characteristics, engagement indicators and outcomes for rural participants enrolled in SIPsmartER, a behavioural intervention targeting sugar-sweetened beverage (SSB) intake.

A secondary data analysis. Bivariate analyses determined relationships among baseline characteristics (e.g. age, gender, race, education, income), engagement indicators (completion of 6-month health screening, class attendance, call completion) and SSB outcomes (SSB ounce reduction (i.e. US fluid ounces; 1 US fl. oz = 29·57 ml), reduced ≥12 ounces, achieved ≤8 ounce intake). Generalized linear models tested for significant effects of baseline characteristics on engagement indicators and of baseline characteristics and engagement indicators on SSB outcomes.

South-west Virginia, USA, a rural, medically underserved region.

Participants’ (n 155) mean age was 41 years; most were female (81 %), White (91 %) and earned ≤$US 20 000 per annum (61 %).

All final models were significant. Engagement models predicted 12–17 % of variance, with age being a significant predictor in all three models. SSB outcome models explained 5–70 % of variance. Number of classes attended was a significant predictor of SSB ounce reduction (β = −6·12, P < 0·01). Baseline SSB intake significantly predicted SSB ounce reduction (β = −0·90, P < 0·001) and achieved ≤8 ounce intake (β = 0·98, P < 0·05).

The study identifies several participant baseline characteristics that may impact engagement in and outcomes from a community-based intervention targeting SSB intake. Findings suggest greater attendance of SIPsmartER classes is associated with greater reduction in overall SSB intake; yet engagement variables did not predict other outcomes. Findings will inform the future implementation of SIPsmartER and research studies of similar design and intent.

To disrupt cycles of health inequity, traceable to dietary inequities in the earliest stages of life, public health interventions should target improving nutritional wellbeing in preconception/pregnancy environments. This requires a deep engagement with pregnant/postpartum people (PPP) and their communities (including their health and social care providers, HSCP). We sought to understand the factors that influence diet during pregnancy from the perspectives of PPP and HSCP, and to outline intervention priorities.

We carried out thematic network analyses of transcripts from ten focus group discussions (FGD) and one stakeholder engagement meeting with PPP and HSCP in a Canadian city. Identified themes were developed into conceptual maps, highlighting local priorities for pregnancy nutrition and intervention development.

FGD and the stakeholder meeting were run in predominantly lower socioeconomic position (SEP) neighbourhoods in the sociodemographically diverse city of Hamilton, Canada.

All local, comprising twenty-two lower SEP PPP and forty-three HSCP.

Salient themes were resilience, resources, relationships and the embodied experience of pregnancy. Both PPP and HSCP underscored that socioeconomic-political forces operating at multiple levels largely determined the availability of individual and relational resources constraining diet during pregnancy. Intervention proposals focused on cultivating individual and community resilience to improve early-life nutritional environments. Participants called for better-integrated services, greater income supports and strengthened support programmes.

Hamilton stakeholders foregrounded social determinants of inequity as main factors influencing pregnancy diet. They further indicated a need to develop interventions that build resilience and redistribute resources at multiple levels, from the household to the state.

To examine cross-sectional associations of four aspects of the consumer food environment – price, availability, marketing and product placement – with BMI and fruit and vegetable intake.

This cross-sectional study measured the consumer food environment using grocery store audits and surveys. Outcomes were measured through surveys and physical exams. Multivariable linear regression models were run; models were all adjusted for age, neighbourhood, education, race/ethnicity and financial burden.

Non-proportional quota sample of four socio-economically and racial/ethnically diverse neighbourhoods in Chicago, IL.

Women (n 228) aged 18–44 years.

Participants who reported seeing healthy food marketing had a higher vegetable intake (β = 0·24, 95 % CI 0·06, 0·42). There was some suggestive evidence that participants who shopped at stores that were more expensive (β = −0·90, 95 % CI −1·94, 0·14) had lower BMI, but this association was not statistically significant. Multivariable regression models did not indicate any significant association between any measure of the consumer food environment and fruit intake.

Our findings add to the growing interest in the role of the consumer food environment in health behaviours. Further research is needed to better understand the role of price and marketing characteristics on eating behaviours and BMI.

Navajo Nation residents experience extreme rates of poverty, food insecurity and diet-related diseases. While many residents travel far to shop at grocery stores, there are small stores closer to home that could provide more healthy options, like fruits and vegetables (F&V). Little is known from the perspective of store owners and managers regarding the barriers and facilitators to offering F&V; the present study contributes to filling that gap.

Data were collected through structured interviews from a sampling frame of all store owners or managers in the setting (n 29).

Small stores in Navajo Nation, New Mexico, USA. Navajo Nation is predominantly rural and the largest federally recognized Native American tribe in the USA.

Sixteen managers and six owners at twenty-two stores.

When asked about the types of foods that were most commonly purchased at their stores, most participants reported snacks and drinks (82 and 68 %, respectively). Many participants reported they would like to offer more fresh F&V. However, barriers included varying perceived customer demand, limited F&V choices from distributors and (for some managers) limited authority over product selection.

Findings contribute to the discussion on engaging store owners and managers in providing quality, healthy foods close to home in low-income, rural regions.

The main objective was to assess the cost, acceptability and affordability of the Cypriot Diabetic Healthy Food Basket (DHFB).

The development of DHFB was based on the Cypriot HFB with adjustments based on the nutritional guidelines for diabetes as developed by the American Diabetes Association (ADA) and information retrieved through the questionnaires. Two DHFB were constructed for adult women and adult men (±40 years) diagnosed with diabetes. Affordability was defined as the cost of DHFB as a percentage of the Guaranteed Minimum Income (GMI).

Cyprus.

422 diabetic patients aged 18–87 years from different socioeconomic backgrounds.

DHFB consists of eight food categories, similar to Cypriot HFB, but different specific food items. The total monthly budget for a diabetic woman is about 15 % (25·68 Euros less) lower compared with HFB, and the relative percentage for a diabetic man is about 16 % (37·58 Euros less). The total monthly budget for a diabetic woman is about 30 % lower (60·32 Euros less) compared with that of a diabetic man. For low-income adults receiving GMI, the proportion of income that would need to be spent on DHFB ranges from around 30 to 42 % for women and men, respectively.

The cost of DHFB is lower compared with HFB, meaning that nutritional treatment based on the practice guidelines for diabetes could be a cost-efficient therapy for these patients. DHFB is still not affordable among low-income persons.

In 2015, beverages were removed from display at a self-service café within a major health service, resulting in fewer purchases of unhealthy beverages. This initiative was continued following initial evaluation of the results. The current study aimed to determine customer acceptability of the initiative, and whether healthier purchases had continued, at 18 months following implementation.

Drinks were categorised as ‘green’ (best choices), ‘amber’ (choose carefully) and ‘red’ (limit), based on the state government nutrient profiling system, for intervention and analysis purposes. In 2015, unhealthy ‘red’ drinks were removed from display. In 2017, weekly beverage sales were counted, through stock-taking, for 6 weeks, and customer surveys were conducted over 2 days.

Café customers (hospital staff, patients and visitors).

Eighteen months after the implementation of the initiative, the proportion of ‘red’ beverages sold was 7 % of total drink sales (compared with 33 % before the removal of unhealthy beverages from display in 2015 (P < 0·001), and 10 % immediately following the removal of unhealthy beverages from display). Customer surveys revealed high levels of acceptability for the initiative and low levels of awareness of the initiative.

The removal of unhealthy beverages from display can result in customers making healthier purchases, and this appears to continue over the long-term. Such interventions have the potential to contribute to the sustained shift in population purchases and consumption needed to make meaningful improvements to population health.

To estimate the impact of recent changes to the Child and Adult Care Food Program (CACFP) meal pattern on young children’s diets in family child care homes (FCCHs) serving racially/ethnically diverse children.

In a natural experimental study of thirteen CACFP-participating FCCHs, we used digital photographs taken of children’s plates before and after meals matched with menus to measure children’s dietary intake both prior to implementation of the new meal patterns (summer/fall of 2017) and again 1 year later (summer/fall of 2018). Generalised estimating equations tested for change in intake of fruits, vegetables, whole grains, 100 % juice, grain-based desserts, meat/meat alternates and milk, adjusting for clustering of observations within providers.

FCCHs in Boston, MA, USA.

Three- to 5-year-old children attending FCCHs.

We observed 107 meals consumed by twenty-eight children at the thirteen FCCHs across an average of 2·5 (sd 1·3) d before the CACFP policy change, and 239 meals consumed by thirty-nine children across 3·8 d (sd 1·4) 1 year later. During lunch, fruit intake increased by about a third of a serving (+0·38 serving, 95 % CI 0·04, 0·73, P = 0·03), and whole grain intake increased by a half serving (+0·50 serving, 95 % CI 0·19, 0·82, P = 0·002). No changes were seen in other meal components.

Young children’s dietary intake in CACFP-participating FCCHs improved following the CACFP meal pattern change, particularly for fruits and whole grains, which were targets of the new policy. Additional research should examine impacts of the changes in other child care settings, age groups and locales.

To evaluate the effect of school-based nutrition interventions (SBNI) involving schoolchildren and adolescents in sub-Saharan Africa (SSA) on child nutrition status and nutrition-related knowledge, attitudes and behaviour.

A systematic review on published school nutrition intervention studies of randomised controlled trials, controlled clinical trials, controlled before-and-after studies or quasi-experimental designs with control. Nine electronic bibliographic databases were searched. To be included, interventions had to involve changes to the school’s physical and social environments, to the school’s nutrition policies, to teaching curriculum to incorporate nutrition education and/or to partnership with parents/community.

Schools in SSA.

School-aged children and adolescents, aged 5–19 years.

Fourteen studies met our inclusion criteria. While there are few existing studies of SBNI in SSA, the evidence shows that food supplementation/fortification is very effective in reducing micronutrient deficiencies and can improve nutrition status. Secondly, school nutrition education can improve nutrition knowledge, but this may not necessarily translate into healthy nutrition behaviour, indicating that nutrition knowledge may have little impact without a facilitating environment. Results regarding anthropometry were inconclusive; however, there is evidence for the effectiveness of SBNI in improving cognitive abilities.

There is enough evidence to warrant further trials of SBNI in SSA. Future research should consider investigating the impact of SBNI on anthropometry and nutrition behaviour, focusing on the role of programme intensity and/or duration. To address the high incidence of micronutrient deficiencies in low- and middle-income countries, food supplementation strategies currently available to schoolchildren should be expanded.

To assess the quantity and focus of recent empirical research regarding the effect of micronutrient supplementation on live birth outcomes in low-risk pregnancies from high-income countries.

A systematic quantitative literature review.

Low-risk pregnancies in World Bank-classified high-income countries, 2019.

Using carefully selected search criteria, a total of 2475 publications were identified, of which seventeen papers met the inclusion criteria for this review. Data contributing to nine of the studies were sourced from four cohorts; research originated from ten countries. These cohorts exhibited a large number of participants, stable data and a low probability of bias. The most recent empirical data offered by these studies was 2011; the most historical was 1980. In total, fifty-five categorical outcome/supplement combinations were examined; 67·3 % reported no evidence of micronutrient supplementation influencing selected outcomes.

A coordinated, cohesive and uniform empirical approach to future studies is required to determine what constitutes appropriate, effective and safe micronutrient supplementation in contemporary cohorts from high-income countries, and how this might influence pregnancy outcomes.

To provide baseline evidence of sugar-sweetened beverage (SSB) consumption in a sample of Irish children prior to the introduction of the SSB tax; to identify the energy contribution of SSB to daily energy intake; and to explore the association between SSB consumption and overweight/obesity.

Cross-sectional study.

Primary schools in Cork, Ireland in 2012.

1075 boys and girls aged 8–11 years. SSB consumption was assessed from 3-d food diaries. BMI was used to define obesity (International Obesity Taskforce definitions). Plausible energy reporters (n 724, 68 % of total sample) were classified using Schofield equation.

Eighty-two per cent of children with plausible energy intake consumed SSB. Mean energy intake from SSB was 485 kJ (6 % of total kJ). Mean kilojoules from SSB increased with weight status from 443 kJ for normal-weight children to 648 kJ for children with overweight/obesity (5·8 and 7·6 % of total kJ, respectively). Mean SSB intake was significantly higher in children with overweight/obesity than normal-weight children (383 and 315 ml/d). In adjusted analyses, children consuming >200 ml/d had an 80 % increased odds of overweight/obesity compared to those consuming <200 ml/d (OR 1·8, 95 % CI 1·0, 3·5). Family socioeconomic status and lifestyle determinants, including frequency of takeaway consumption and TV viewing, were also significantly associated with SSB consumption.

SSB account for a substantial proportion of daily energy intake and are significantly associated with child overweight/obesity. This study provides baseline data from a sample of children from which the impact of the SSB tax can be benchmarked.

To compare federally reimbursable school meals served when competitive foods are removed and when marketing and nudging strategies are used in school cafeterias operating the National School Lunch Program (NSLP). The second objective was to determine how marketing and nudging strategies influence competitive food sales.

In the Healthy Choices School, all competitive foods were removed; the Healthy Nudging School retained competitive foods and promoted the school meal programme using marketing and nudging strategies; a third school made no changes. Cafeteria register data were collected from the beginning of the 2013–2014 school year through the four-week intervention. Outcome measures included daily entrées served; share of entrées served with vegetables, fruit and milk; and total competitive food sales. Difference-in-difference models were used to examine outcome measure changes.

Three high schools in a diverse, Northeast US urban district with universally free meals.

High-school students participating in the NSLP.

During the intervention weeks, the average number of entrées served daily was significantly higher in the Healthy Choices School (82·1 (se 33·9)) and the Healthy Nudging School (107·4 (se 28·2)) compared with the control school. The only significant change in meal component selection was a 6 % (se 0·02) higher rate of vegetable servings in the Healthy Choices School compared with the control school. Healthy Nudging School competitive food sales did not change.

Both strategies – removing competitive foods and marketing and nudging – may increase school meal participation. There was no evidence that promoting school meals decreased competitive food sales.

A tax on sugar-sweetened beverages (SSB) was introduced in South Africa in April 2018. Our objective was to document perceptions and attitudes among urban South Africans living in Soweto on factors that contribute to their SSB intake and on South Africa’s use of a tax to reduce SSB consumption.

We conducted six focus group discussions using a semi-structured guide.

The study was conducted in Soweto, Johannesburg, South Africa, 3 months before South Africa’s SSB tax was implemented.

Adults aged 18 years or above living in Soweto (n 57).

Participants reported frequent SSB consumption and attributed this to habit, addiction, advertising and wide accessibility of SSB. Most of the participants were not aware of the proposed SSB tax; when made aware of the tax, their responses included both beliefs that it would and would not result in reduced SSB intake. However, participants indicated cynicism with regard to the government’s stated motivation in introducing the tax for health rather than revenue reasons.

While an SSB tax is a policy tool that could be used with other strategies to reduce people’s high level of SSB consumption in Soweto, our findings suggest a need to complement the SSB tax with a multipronged behaviour change strategy. This strategy could include both environmental and individual levers to reduce SSB consumption and its associated risks.

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.
