To assess the association of obesogenic environmental characteristics around schools with body adiposity and adipokine concentrations in Brazilian children.

Cross-sectional study. Body adiposity was assessed using the dual-energy X-ray absorptiometry. Concentrations of leptin, adiponectin, retinol-binding protein 4 (RBP4) and chemerin were measured. Predominantly ultra-processed food (UPF) stores, public physical activity (PA) facilities, green spaces, walkability, traffic accidents and crime were evaluated. The neighbourhood unit was the 400 m (0·25 miles) road network buffer around schools. The association of environmental characteristics with body adiposity and adipokine concentrations was assessed by linear regression models using generalised estimating equations.

Urban schools (n 24), Viçosa, Minas Gerais, Brazil.

Children aged 8 and 9 years (n 378).

A higher density of predominantly UPF stores and a lower percentage of green space were associated with higher total (β: 0·12; 95 % CI 0·06, 0·18 and β: –0·10; 95 % CI –0·16, –0·04, respectively) and android body fat (β: 0·28; 95 % CI 0·13, 0·43 and β: –0·18; 95 % CI –0·32, –0·04, respectively). In addition, the densities of PA facilities and crime were inversely associated with leptin concentrations. Traffic accidents density and percentage of green spaces around schools had, respectively, a positive and an inverse association with concentrations of adiponectin and RBP4.

Obesogenic environmental characteristics around schools were associated with total and android body fat, as well as with pro-inflammatory adipokine concentrations in Brazilian children from a medium-sized city.

Night shift workers are at a 20 to 40 % increased risk of metabolic diseases, which may be associated with their disrupted eating patterns. This qualitative study explores factors that influence night shift workers’ eating habits, within and outside of the workplace, to identify target areas for health promotion strategies.

Eligible participants resided in Australia, working at least three overnight shifts per month.

The photovoice method was used, whereby participants were asked to take photos that represent their typical eating habits. These photos were incorporated as prompts in a semi-structured interview, which explored factors influencing eating habits on night shifts and days-off and perceptions and enablers to healthy eating.

Ten participants completed the study. Thematic analysis generated four main themes, which were mapped onto the Social Ecological Model (SE Model). Aligned with the SE Model, our results show night shift workers’ eating habits are influenced by intrapersonal, interpersonal and (work) organisational levels. Participants reported that at work, appropriate food preparation facilities are required to enable healthy food choices. Poor shift work rostering leads to prolonged fatigue on days-off, limiting their ability and motivation to engage in healthy eating. Consequently, night shift workers seem to require additional supports from their social networks and enhanced food literacy skills, in order to adopt/ maintain healthy eating behaviours.

Night shift work creates individual and environmental barriers to healthy eating, which are present during and outside of work. Health promotion strategies for this population should include multiple approaches to address these barriers.

To evaluate snacking and diet quality among US adolescents.

Cross-sectional analysis examined snack frequency (snacks/day), size (kcal/snack) and energy density (kcal/g/snack) as predictors of diet quality using the mean of two 24-h dietary recalls. Diet quality was assessed using the Healthy Eating Index (HEI-2015, 0–100), a mean adequacy ratio (MAR, 0–100) for under-consumed nutrients (potassium, fibre, Ca, vitamin D) and mean percentage of recommended limits for over-consumed nutrients (added sugar, saturated fat, Na). Linear regression models examined total snacks, food only snacks and beverage only snacks, as predictors of diet quality adjusting for demographic characteristics and estimated energy reporting accuracy.

2007–2018 National Health and Nutrition Examination Survey.

Adolescents 12–19 years (n 4985).

Snack frequency was associated with higher HEI-2015 (β = 0·7 (0·3), P < 0·05) but also with higher intake of over-consumed nutrients (β = 3·0 (0·8), P ≤ 0·001). Snack size was associated with lower HEI (β = –0·005 (0·001), P ≤ 0·001) and MAR (β = –0·005 (0·002), P < 0·05) and higher intake of over-consumed nutrients (β = 0·03 (0·005), P ≤ 0·001). Associations differed for food only and beverage only snacks. Food only snack frequency was associated with higher HEI-2015 (β = 1·7 (0·03), P ≤ 0·001), while food only snack size (β = –0·006 (0·0009), P ≤ 0·001) and food only snack energy density (β = –1·1 (0·2), P ≤ 0·001) were associated with lower HEI-2015. Conversely, beverage only snack frequency (β = 4·4 (2·1) P < 0·05) and beverage only snack size (β = 0·03 (0·01), P ≤ 0·001) were associated with higher intake of over-consumed nutrients.

Smaller, frequent, less energy-dense food only snacks are associated with higher diet quality in adolescents; beverages consumed as snacks are associated with greater intake of over-consumed nutrients.

To assess the relationship between programme attendance in a produce prescription (PRx) programme and changes in cardiovascular risk factors.

The Georgia Food for Health (GF4H) programme provided six monthly nutrition education sessions, six weekly cooking classes and weekly produce vouchers. Participants became programme graduates attending at least 4 of the 6 of both the weekly cooking classes and monthly education sessions. We used a longitudinal, single-arm approach to estimate the association between the number of monthly programme visits attended and changes in health indicators.

GF4H was implemented in partnership with a large safety-net health system in Atlanta, GA.

Three hundred thirty-one participants living with or at-risk of chronic disease and food insecurity were recruited from primary care clinics. Over three years, 282 participants graduated from the programme.

After adjusting for programme site, year, participant sex, age, race and ethnicity, Supplemental Nutrition Assistance Program participation and household size, we estimated that each additional programme visit attended beyond four visits was associated with a 0·06 kg/m2 reduction in BMI (95 % CI –0·12, –0·01; P = 0·02), a 0·37 inch reduction in waist circumference (95 % CI –0·48, –0·27; P < 0·001), a 1·01 mmHg reduction in systolic blood pressure (95 % CI –1·45, –0·57; P < 0·001) and a 0·43 mmHg reduction in diastolic blood pressure (95 % CI –0·69, –0·17; P = 0·001).

Each additional cooking and nutrition education visit attended beyond the graduation threshold was associated with modest but significant improvements in CVD risk factors, suggesting that increased engagement in educational components of a PRx programme improves health outcomes.

This review aimed to identify and synthesise the enablers and barriers that influence the long-term (≥ 2 years) sustainment of school-based nutrition programmes.

Four databases (PubMed, Cochrane Library, Embase and Scopus) were searched to identify studies reporting on the international literature relating to food and nutrition programmes aimed at school-age (5–14 years) children that had been running for ≥ 2 years (combined intervention and follow-up period). Eligible studies were analysed using the Integrated Sustainability Framework (ISF), which involved deductive coding of programme enablers and barriers. A quality assessment was completed, using the Mixed-Methods Appraisal Tool and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

International school-based nutrition programmes.

Individuals involved with the implementation of school-based nutrition programmes.

From the 7366 articles identified, thirteen studies (seven qualitative, five mixed methods and one quantitative descriptive) were included, from which the enablers and barriers of eleven different nutrition-related programmes were analysed. Thirty-four factors across the five domains of the ISF were identified that influenced the sustained implementation of programmes. The most common barrier was a lack of organisational readiness and resources, whereas the most common enabler was having adequate external partnerships and a supportive environment.

These findings have application during the initiation and implementation phases of school-based nutrition programmes. Paying attention to the ‘outer contextual factors’ of the ISF including the establishment and maintenance of robust relationships across whole of government systems, local institutions and funding bodies are crucial for programme sustainment.

We examined the association between food insecurity and positive childhood experiences (PCE).

Outcome measure was number of PCE and seven PCE constructs. Food insecurity was assessed with a three-category measure that ascertained whether the respondent could afford and choose to eat nutritious food. We then used bivariate and multivariable Poisson and logistic regressions to analyse the relationship between food insecurity and the outcome measures. The analyses were further stratified by age (≤ 5, 6–11 and 12–17 years).

The National Survey of Children’s Health (NSCH) from 2017 to 2020, a nationally representative sample of children and adolescents in the USA.

Parents/caregivers who reported on their children’s experiences of PCE and food insecurity from the 2017–2020 NSCH (n 114 709).

Descriptively, 22·13 % of respondents reported mild food insecurity, while 3·45 % of respondents reported moderate to severe food insecurity. On multivariable Poisson regression analyses, there was a lower rate of PCE among children who experienced mild (incidence rate ratio (IRR) = 0·93; 95 % CI 0·92, 0·94) or moderate/severe food insecurity (IRR = 0·84; 95 % CI 0·83, 0·86) compared with those who were food secure. We found an inverse relationship between food insecurity and rate of PCE across all age categories.

Our study finding lends evidence to support that interventions, public health programmes, as well as public health policies that reduce food insecurity among children and adolescents may be associated with an increase in PCE. Longitudinal and intervention research are needed to examine the mechanistic relationship between food insecurity and PCE across the life course.

The current study presents results of a midpoint analysis of an ongoing natural experiment evaluating the diet-related effects of the Minneapolis Minimum Wage Ordinance, which incrementally increases the minimum wage to $15/h.

A difference-in-difference (DiD) analysis of measures collected among low-wage workers in two U.S. cities (one city with a wage increase policy and one comparison city). Measures included employment-related variables (hourly wage, hours worked and non-employment assessed by survey questions with wages verified by paystubs), BMI measured by study scales and stadiometers and diet-related mediators (food insecurity, Supplemental Nutrition Assistance Program (SNAP) participation and daily servings of fruits and vegetables, whole-grain rich foods and foods high in added sugars measured by survey questions).

Minneapolis, Minnesota and Raleigh, North Carolina.

A cohort of 580 low-wage workers (268 in Minneapolis and 312 in Raleigh) who completed three annual study visits between 2018 and 2020.

In DiD models adjusted for time-varying and non-time-varying confounders, there were no statistically significant differences in variables of interest in Minneapolis compared with Raleigh. Trends across both cities were evident, showing a steady increase in hourly wage, stable BMI, an overall decrease in food insecurity and non-linear trends in employment, hours worked, SNAP participation and dietary outcomes.

There was no evidence of a beneficial or adverse effect of the Minimum Wage Ordinance on health-related variables during a period of economic and social change. The COVID-19 pandemic and other contextual factors likely contributed to the observed trends in both cities.
