Restructuring food environments – such as increasing vegetarian meal availability – has been shown to influence dietary choices in online and university canteen settings. However, evidence from more diverse populations is limited. METHODS : We conducted a stepped-wedge cluster-randomised controlled trial in six English worksite cafeterias over seven weeks. The intervention involved replacing one meat-based meal on the lunch menu with a vegetarian option. Likelihood of selecting a vegetarian meal (primary outcome) was analysed in a logistic regression with random intercept for cafeteria and fixed effect for time. Secondary outcomes included nutritional and sustainability markers (e.g., kilocalories, greenhouse gas (GHG) emissions), revenue, and food waste. Interviews with cafeteria staff and customers explored intervention acceptability and barriers. RESULTS : The intervention encompassed 26,170 meal sales over 42 site-weeks. The intervention increased the likelihood of selecting a vegetarian meal by 41% [95% CI: 28 to 55]. Per-meal kilocalories were reduced by 26.1 [95% CI -34.4 to -17.7], and per-meal GHGs by 0.16 kg CO2-eq [-0.22 to -0.11]. No significant negative impacts on business outcomes such as cafeteria revenue (-98.43 GBP [-436.03 to 239.17]) or food waste (-8.25 kg [-48.38 to 31.87]; -61.64 GBP [-306.80 to 183.53]) were found. Customers and staff reported that the intervention was acceptable, non-intrusive, and easy to implement, with concerns about customer dissatisfaction and food waste not confirmed by our data. Suggestions for improvement included greater attention to pricing and taste to further encourage uptake. CONCLUSIONS : Increasing the availability of vegetarian meals in cafeterias can significantly shift food choices and reduce environmental impact and calories consumed, without compromising business outcomes, and should be considered an effective strategy for sustainability and public health in diverse food service settings.

While physical activity (PA) is recognized as a beneficial non-pharmacological intervention, its precise dose-response relationship with subjective sleep quality remains insufficiently quantified. This study aimed to systematically evaluate the efficacy of PA on subjective sleep quality in patients with insomnia and to quantitatively delineate the dose–response relationship using Bayesian meta-analysis. METHODS: A systematic search was conducted across Web of Science, PubMed, Embase, PsycINFO, and the Cochrane Library from inception to February 2026. Randomized controlled trials (RCTs) investigating the effects of PA on subjective sleep quality in participants diagnosed with insomnia were included. A Bayesian random-effects meta-analysis was performed to calculate pooled effect sizes (Hedges’g) with 95% Credible Intervals (CrI). Dose–response relationships were modelled using restricted cubic splines to identify minimum and optimal dosages. Dosage was expressed as the weekly volume in MET-minutes (Metabolic Equivalent of Task × minutes/week). The certainty of evidence was assessed using the GRADE approach. RESULTS: 24 RCTs involving 1,591 participants were included. Bayesian synthesis indicated low evidence that PA significantly improves subjective sleep quality compared with inactive controls (Hedges’g = -0.56, 95% CrI: -0.68, -0.45). Dose–response analysis revealed a non-linear “L-shaped” relationship. Benefits accrued rapidly at lower volumes, with a minimum effective dose estimated at 100 METs-min/week. The therapeutic effect peaked at an optimal dose of approximately 650 METs-min/week (Hedges’g = -0.64, 95% CrI: -0.85, -0.44), beyond which additional volume yielded diminishing marginal returns. Moderation analyses indicated that the effect was more pronounced in adults (Hedges’ g = -1.00) than in older adults (Hedges’ g = -0.51), and was consistent across different diagnostic methods and measurement instruments. Various types of exercise, including aerobic, strength, mind-body, and multicomponent training, all demonstrated beneficial effects. CONCLUSIONS: Physical activity is an effective treatment for insomnia, characterized by an L-shaped dose–response curve. The relationship is characterized by a rapid initial benefit at low volumes, with a statistically significant response observed at 100 MET-min/week and a plateau in effect occurring at approximately 650 MET-min/week, beyond which additional volume yields diminishing returns.

Few studies have investigated the associations between the physical and social environment and the full movement behaviour composition, including times spent in moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), sedentary behaviour, and sleep, and their findings are inconsistent. Therefore, our aim was to investigate this association in a large, national-representative sample of schoolchildren from major cities and regional/remote areas. METHODS: We used data from the Longitudinal Study of Australian Children and the Child Health CheckPoint study, collected among 1230 child-parent pairs (child age range: 10–12 years). Parents were asked about neighbourhood general safety, access to destinations and services, and social capital and cohesion. Children’s time spent in MVPA, LPA, sedentary behaviour, and sleep was assessed using wrist-worn GENEActiv accelerometers. The associations between the physical and social environment characteristics (independent variables) and movement behaviour composition expressed as isometric log ratio coordinates (dependent variables) were examined using multiple linear regression analyses, adjusted for age, body mass index, pubertal status, sex, and socioeconomic position. RESULTS: Among schoolchildren from regional/remote areas, access to destinations and services (Pillai’s trace = 0.030; p = 0.010), as well as social capital and cohesion (Pillai’s trace = 0.024; p = 0.032) were associated with movement behaviour composition. In specific, better access to destinations and services was associated with higher MVPA and lower LPA, while higher social capital and cohesion were associated with higher MVPA and LPA, and lower sedentary behaviour (with negligible changes in the remaining movement behaviours). We did not find a significant association between general safety and the movement behaviour composition among schoolchildren from regional/remote areas (Pillai’s trace = 0.005; p = 0.641) or any significant associations among schoolchildren from major cities (p > 0.050 for all). CONCLUSIONS: These findings highlight the importance of access to destinations and services, as well as social capital and cohesion, in shaping the movement behaviour composition among schoolchildren from regional/remote areas.

This study aimed to evaluate its internal consistency, relative validity, construct validity, as well as end-user acceptability. METHODS: A validation study was conducted among 106 adults in Spain. Participants completed REFRESH-daily for seven days via a mobile application, alongside a 7-day digital food diary as the reference method. Internal consistency was assessed using Cronbach’s alpha. Relative validity was evaluated through multi-level Bland–Altman analyses comparing REFRESH-daily with food diary data. Construct validity was tested by examining associations between REFRESH-daily score and food consumption, nutrient intake, estimated health risks based on the Global Burden of Disease framework, and environmental impact via Life Cycle Assessment methodology. Likert-scales were used to assess acceptability. RESULTS: REFRESH-daily showed good internal consistency (Cronbach’s alpha = 0.71). Relative validity analyses showed a small mean difference of 0.3 points (out of 10) between REFRESH-daily and food diary scores. Higher REFRESH-daily scores were associated with greater intake of whole plant-based foods, health-promoting nutrients, lower estimated disease risks, and reduced environmental impacts. User acceptability was high. CONCLUSIONS: REFRESH-daily is a valid, reliable and user-friendly tool for assessing alignment with environmentally sustainable healthy diets. Its ease of use and sensitivity to subtle dietary shifts make it particularly well-suited for the integration into behavioral dietary interventions serving as a key tool for tracking progress and informing feedback in research and applied settings. </p>","PeriodicalId":50336,"journal":{"name":"International Journal of Behavioral Nutrition and Physical Activity","volume":" ","pages":""},"PeriodicalIF":7.1,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13227659/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147596247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, few randomized trials have examined implementation of PSE strategies and their impacts in rural adult populations. This study evaluated implementation of Cooperative Extension-led Change Club (CC) community project action plans aimed at facilitating PSE change in six rural and micropolitan Texas and New York intervention communities.

METHODS: CCs followed a 24-module curriculum facilitated by trained Extension educators. Approved action plans were provided with seed money to target diet and physical activity PSE changes. Implementation outcomes regarding the action plans were tracked through educator reports, interviews, and proposals. CFIR factors were assessed during the early stages of action plan implementation using interviews with educators and participant residents. RESULTS: All six intervention communities implemented action plans, most of which had multiple components. Each prioritized environmental changes and most focused on addressing physical activity. Implementation timing and continuity varied, influenced by external factors such as weather and local approvals. CFIR analysis identified beliefs about feasibility, stakeholder engagement, and group decision-making as key factors influencing implementation.

Some general parenting constructs have been associated with children’s health behaviors. However, overprotective parenting—marked by excessive involvement and control with limited autonomy support relative to the child’s developmental level—remains largely understudied in relation to preschoolers’ physical activity (PA) and screen time (ST), as do the potential moderating effects of sociodemographic variables in these associations. Therefore, we examined the associations of overprotection with PA and ST among Finnish preschoolers and explored whether parental education or children’s sex moderated these associations. METHODS: This cross-sectional study included 798 Finnish 3–6-year-olds and their parents from the DAGIS Survey. Parents completed an overprotection scale from an item-reduced version of the Comprehensive General Parenting Questionnaire. Children’s ST was parent-reported via a seven-day diary, while PA was measured with Actigraph accelerometers (for seven days). Weekday, weekend, and overall averages were computed for ST, moderate-to-vigorous physical activity (MVPA), and total physical activity (TPA). Linear mixed-effects models were used for analyses. The models were adjusted for the child’s age and sex, parental education, number of children in the household, birth order, and questionnaire respondent (mother/father). Moderation by sex and education was tested by adding the corresponding interaction terms to the models. RESULTS: Children’s weighted averages were 71 min of MVPA, 398 min of TPA, and 76 min of ST per day. Overprotection was inversely associated with weekend MVPA (B: -3.49, 95%CI: -6.50; -0.48), weekend TPA (B: -9.94, 95%CI: -16.56; -3.34), and overall average TPA (B: -5.70, 95%CI: -10.78; -0.64). No associations with ST were found, nor were any associations moderated by sex or parental education. CONCLUSIONS: These results suggest an association between higher overprotection and lower PA among preschool-aged children regardless of child sex and parental educational level. We hypothesize that overprotective parents may, for example, restrict children’s PA due to safety concerns. Although the mechanisms and causality of the associations found require further investigation, identifying and addressing overprotective parenting could be beneficial in PA-promoting interventions. </p>","PeriodicalId":50336,"journal":{"name":"International Journal of Behavioral Nutrition and Physical Activity","volume":" ","pages":""},"PeriodicalIF":7.1,"publicationDate":"2026-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13154676/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147534190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces a percentile-based scoring and visualization approach to evaluate the healthfulness of movement behaviour time-use compositions, using social-emotional development in early childhood as an example. METHODS: This cross-sectional study includes 560 children aged 1.2–2.9 years and 1,500 children aged 3.0-4.9 years from Sleep and Activity Database for the Early Years (SADEY), an international accelerometer repository of young children’s movement behaviours. Sedentary time, light physical activity, and moderate-to-vigorous physical activity were measured using accelerometers. Sleep duration was parent-reported. Social-emotional development was assessed using age- and sex-normalized scores from the Strengths and Difficulties Questionnaire. Linear regression models with compositional covariates were used to model associations between movement behaviours and Strengths and Difficulties Questionnaire scores. Representative grids containing all possible time-use compositions (in 5 min/d increments) of sleep, sedentary time, light physical activity, and moderate-to-vigorous physical activity were developed. The regression models were applied to each time-use composition in the grid, and the predicted scores were ranked to create percentile scores for different movement behaviour time-use compositions. RESULTS: The 24-hour movement behaviour composition was associated with all five Strengths and Difficulties Questionnaire scores in both age groups (p ≤ 0.01). The grids contained 17,577 and 16,535 possible time-use compositions for 1–2 and 3–4-year-olds, respectively. Time-use compositions ranked at the 0th percentile had the least sleep and highest sedentary time, while those ranked at the 100th percentile had the most sleep and least sedentary time. Across the central range of the percentile score distribution (e.g., rankings between the 25th to 75th percentiles), some very different time-use compositions had the same percentile score. Interactive visualization tools were presented to enable real-time exploration of percentile scores for various movement behaviour time-use compositions. CONCLUSIONS: This study introduces a novel approach to evaluate the health benefits of movement behaviours. This approach moves beyond traditional binary cutoffs to recognize the gradual improvements in health that occur with small changes in behaviours, and that there are multiple pathways to achieving the same health benefits. </p>","PeriodicalId":50336,"journal":{"name":"International Journal of Behavioral Nutrition and Physical Activity","volume":" ","pages":""},"PeriodicalIF":7.1,"publicationDate":"2026-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13137636/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147505352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
