Sustainable, theory-driven interventions are essential to address these challenges and promote cardiovascular health in this vulnerable population. This study evaluated the effectiveness of a novel music-visual guided PA intervention (MVgPA) in increasing moderate-to-vigorous PA time, improving self-efficacy and interest in PA, and enhancing functional exercise capacity among adults with ID in supported care settings. It also assessed the intervention’s acceptability among participants and care staff. METHODS: In a 25-week cluster-randomized controlled trial, 16 supported care settings (N = 238 adults with mild-to-moderate ID) were randomized 1:1 to MVgPA (n = 8 settings, 120 participants; staff training plus twice-weekly 75-minute music-paced, visually cued PA sessions) or usual care (n = 8 settings, 118 participants). The Information-Motivation-Strategy (IMS)-based MVgPA intervention targeted knowledge, motivation, and practical strategies. The primary outcome was accelerometer-measured moderate-to-vigorous PA time. Secondary outcomes included functional exercise capacity (6-minute walk test), exercise self-efficacy (Baseline Interview Questionnaire), and PA interest (visual analogue scale). Outcomes were measured at baseline, 13, and 25 weeks, and analyzed using three-level mixed-effects models accounting for clustering, repeated measures, and individual variability. RESULTS: No significant between-group differences emerged in moderate-to-vigorous PA time. Compared to controls, the MVgPA group showed significant improvements in functional exercise capacity at 13 weeks (Time*Group interaction coefficient, β: 20.89, 95% CI: 7.81 to 33.98, p = 0.002) and 25 weeks (β: 16.78, 95% CI: 2.44 to 31.12, p = 0.02); exercise self-efficacy at 13 weeks (β: 0.60, 95% CI: 0.10 to 1.10, p = 0.02) and 25 weeks (β: 0.96, 95% CI: 0.42 to 1.49, p < 0.001), and PA interest at 13 weeks (β: 1.22, 95% CI: 0.48 to1.96, p = 0.001) and 25 weeks (β:1.76, 95% CI: 0.98 to 2.55, p < 0.001). All intervention settings committed to sustaining MVgPA post-trial. The trial achieved 100% participant retention and demonstrated high acceptability (staff willingness scores: 4 to 6/6). CONCLUSIONS: The IMS-based MVgPA intervention significantly improved functional and psychosocial outcomes associated with cardiovascular health in adults with ID, despite no increase in objectively measured PA. The intervention’s high acceptability and sustainability support its scalable implementation in supported care settings.

LvL UP (\"Level Up\") is a holistic mHealth lifestyle coaching intervention that integrates physical activity, diet, and emotional regulation. It provides blended coaching support through an app-based conversational agent with adaptive human support. This pilot trial assessed the feasibility of delivering the LvL UP intervention and implementing its adaptive procedures using a sequential multiple assignment randomised trial (SMART) design.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This eight-week pilot trial was conducted from 29 March to 1 August 2024. We recruited adults in Singapore aged 21-59 at risk of chronic conditions. Participants were randomised 2:1 to the intervention (LvL UP app with a peer supporter-LvL UP Buddy) or comparison (control app with educational resources). After four weeks, non-responders (defined as completing &lt; 6 digital coaching sessions or rated session usefulness &lt; 4/5) were re-randomised 1:1 to continue or receive three additional motivational interviewing (MI)-informed sessions with a human coach; responders remained on their original allocation. Primary outcomes included feasibility indicators: recruitment, LvL UP Buddy enrolment, non-responder rate, trial retention, data completion rate, and intervention engagement. Secondary outcomes measured changes from baseline to eight weeks in mental well-being, psychological distress, physical activity, sleep duration, and fruit and vegetable intake. Six progression criteria were prespecified to guide advancement to a definitive trial.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Of the 458 individuals screened, 394 were eligible, and 123 were enrolled (82 interventions; 41 controls). Most intervention participants (95.1%) were paired with a LvL UP Buddy. Thirty-eight participants (46.3%) were non-responders; of those assigned to MI-informed sessions, 52.6% (10/19) completed all three. Eight-week retention was high (91.5% intervention; 92.7% control), with 12.2% missing data. Positive trends were observed in mental well-being (2.12, 95% CI [-0.58, 4.82]), psychological distress (-0.94 [-2.08, 0.20]), and sleep duration (0.49 h/week [0.17, 0.82]). The study met five of six prespecified progression criteria: recruiting ≥ 60 participants within six weeks, achieving ≥ 75% retention, maintaining ≤ 20% missing data, obtaining a 40-60% non-responder rate, and showing a positive change in ≥ 1 health-related outcome. The digital coaching session adherence fell below the target (39.5% vs. 70%).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;LvL UP was feasible to deliver and evaluate using a SMART design.

METHODS: MEDLINE (OVID), Embase (OVID), Emcare (OVID), SPORTDiscus, Web of Science, Scopus and Cochrane (CINAHL) were searched from January 2010 to February 2025. Randomized controlled trials published in English, targeting adults, that prescribed resistance training via an mHealth platform and measured at least one outcome of neuromuscular fitness or resistance training participation were included. RESULTS: From the 12,059 records identified, 32 RCTs were included. mHealth-delivered resistance training interventions produced a small, statistically significant improvement in neuromuscular fitness compared with no intervention/usual care (Cohen’s d = 0.18, 95% CI [0.08, 0.28], p < .001, 18 studies). There was a significant, moderate effect for lower body neuromuscular fitness outcomes, but no significant effect for upper body outcomes. Only two studies measured changes to resistance training participation, precluding meta-analysis on this outcome. Studies targeted mostly clinical populations and used mobile applications or websites.

While China has implemented numerous PA interventions, little is known about how these programs address or overlook equity considerations. This scoping review synthesizes evidence on equity measures in PA interventions among Chinese children. METHODS: A scoping review was conducted following the guidance of PROGRESS-Plus framework to assess equity measures across PA interventions for children in China. Published studies were analysed to identify equity-related indicators including place of residence, ethnicity, occupation, sex, education, and household income. This review was registered on OSF registries ( https://osf.io/zbfpd ). RESULTS: Sixty-five individual interventions were identified. Equity considerations were rarely explicit. Most interventions were concentrated in well-developed cities, with only two conducted in rural regions. Male participants slightly outnumbered females. Children from families with lower parental education or occupational status, as well as those from ethnic minoritised groups and children who are left-behind or displaced, were consistently underrepresented. While a number of interventions focused on children with health issues, these efforts were not intentionally designed to address PA inequities. CONCLUSIONS: Equity considerations are largely absent from PA interventions for Chinese children. The disproportionate region and sex focus, combined with neglect of rural, minority, and disadvantaged groups, suggests these interventions may unintentionally widen health disparities. Future efforts should apply an equity lens in PA interventions by prioritizing underserved children and considering upstream, policy-level strategies to promote fair and inclusive PA opportunities. </p>","PeriodicalId":50336,"journal":{"name":"International Journal of Behavioral Nutrition and Physical Activity","volume":" ","pages":"9"},"PeriodicalIF":7.1,"publicationDate":"2025-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12838491/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145811767","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}

Summer day camps (SDCs) provide access to healthful meals and a structured environment; yet low-income families often cannot afford SDCs which may influence food/beverage consumption. This study examined the impact of receiving a free SDC versus experiencing summer as usual (SAU) on dietary intake during summer among children from low-income families. METHODS: Parent-child dyads (N = 422; child age: 8.2 ± 1.5 yrs; 48% female; 51% Black) were recruited over 3 years (2021–2023) from schools serving families with low-income. Children were randomized to receive 8–10 weeks of free SDC (intervention) or SAU (control). Parents completed daily diaries for 14 days during school (April/May) and summer (July) which captured child consumption of healthful (e.g., fruit, vegetables, milk) and unhealthful (e.g., soda, fast food, snacks/chips) foods/beverages. Mixed-effects intent-to-treat (ITT) models examined the odds of consuming different foods/beverages during summer, controlling for school year consumption, in the SDC group compared to SAU. Secondary as-treated analyses examined the impact of attending structured summer programming versus not attending on the odds of consuming different food/beverages, regardless of randomization. RESULTS: A total of 2,931 daily diaries were completed for intervention (n = 232) and control (n = 201) children. ITT analyses showed the SDC group had decreased odds of consuming frozen desserts (OR 0.68, 95%CI 0.49–0.94), compared to SAU, during summer weekdays. No other differences were observed. As-treated analyses showed children had increased odds of consuming fruit (1.77, 1.30–2.41), milk (1.97, 1.44–2.69), and chips/snacks (1.49, 1.17–1.90), and decreased odds of consuming soda (0.53, 0.34–0.84), fast food (0.57, 0.45–0.73), and frozen desserts (0.58, 0.45–0.74) on weekdays when they attended structured summer programming, compared to days they did not attend. CONCLUSIONS: Providing free SDC alone did not promote more healthful food/beverage consumption during summer vacation compared to SAU. However, on days children attended a structured program, children experienced more dietary benefits compared to days they did not. Thus, structured environments may positively impact children’s diet during summer; yet, identifying strategies to address barriers beyond cost to improve attendance and enrollment may enhance the impact of summer programming. </p>","PeriodicalId":50336,"journal":{"name":"International Journal of Behavioral Nutrition and Physical Activity","volume":" ","pages":"160"},"PeriodicalIF":7.1,"publicationDate":"2025-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12751208/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145795134","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}
