However, no research to date has explored its association with mortality in a nationally representative population. This study aimed to examine the dose-response association between VILPA and mortality risk in a nationally representative sample of US adults. METHODS: This study included a nationally representative sample of 3293 US adults from the 2011-14 National Health and Nutrition Examination Survey (NHANES) who self-reported no participation in structured exercise (52.3% female; mean age: 50.7 [SD: 16.6 years]. The dose-response relationship between VILPA and all-cause mortality was estimated using multivariable-adjusted cubic splines. Average daily frequency (bouts/day) and duration (minutes/day) of VILPA bouts lasting up to one minute were measured using a wrist-worn accelerometer. RESULTS: Over the mean (SD) 6.7 (1.4) year follow-up period, 290 all-cause mortality events occurred. Compared to the referent point (0 bouts per day), there was an L-shaped dose-response association where the median frequency (5.3 bouts per day) was associated with a 44% lower risk of all-cause mortality (HR: 0.56; 95% CI: 0.39, 0.82). The dose response curve was less steep beyond approximately 8 bouts per day (HR: 0.46; 95% CI: 0.28, 0.77). Findings for the median frequency of VILPA bouts (5.3 bouts per day) remained consistent after excluding participants with poor health (HR: 0.51: 95% CI: 0.29, 0.87) and those who completed no VILPA (HR: 0.57: 95% CI: 0.38, 0.86). When excluding adults with prevalent cardiovascular disease or cancer at baseline (n = 2,731, 152 events), the dose-response relationship was similar, although the 95% CIs crossed unity for most of the curve (e.g. median frequency of VILPA bouts HR: 0.68: 95% CI: 0.41, 1.11). CONCLUSIONS: In a nationally representative sample of US adults, short bursts of intermittent vigorous physical activity were associated with a lower risk of mortality. Excluding those with prevalent cardiovascular disease and cancer led to attenuated dose-response curves and wider confidence intervals, suggesting that the observed relationships may, at least partly, be driven by existing disease-induced reverse causation. While these results highlight some potential of VILPA as a time-efficient source of activity, additional observational studies with longer follow up and larger sample sizes are warranted. </p>","PeriodicalId":50336,"journal":{"name":"International Journal of Behavioral Nutrition and Physical Activity","volume":" ","pages":""},"PeriodicalIF":7.1,"publicationDate":"2026-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12952009/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146088037","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 systematic review and meta-analysis synthesised evidence on the association between life satisfaction and health behaviours such as smoking status, alcohol use, physical activity, diet/nutrition, and sleep among older adults aged 60 years and older. METHODS: The review was conducted and reported following the PRISMA guidelines. We searched the electronic databases MEDLINE, APA PsycINFO, Web of Science, CINAHL, and Global Health from inception to 10 January 2025 for observational studies reporting an association between life satisfaction and health behaviours. Two independent reviewers completed article screening, data extraction, and risk of bias assessment. The result was summarised through a narrative synthesis, and meta-analysis was completed using CMA (version 4). RESULTS: The 56 included studies were conducted across 22 countries between 1990 and 2025. The pooled mean age and female proportion were 70.59 years (95% CI: 68.98, 72.21) and 58.0% (95% CI: 55.1, 60.7), respectively. Narrative synthesis showed that most studies found quality sleep and/or 7–8 h of sleep (77.3%), a higher physical activity level (69.1%), and a regular intake of fruit and vegetables and/or a balanced diet regularly (52.9%) were significantly associated with higher life satisfaction. Smoking and alcohol use were associated with lower life satisfaction in 33.3% and 15.8% of the analysis, respectively. The meta-analysis showed that higher physical activity levels (r = 0.12, p = 0.003) were associated with higher life satisfaction. Only four studies on physical activity met the criteria for meta-analysis, and no studies on other health behaviours did. CONCLUSIONS: Quality sleep and/or 7–8 h of sleep, a higher physical activity level, and regularly eating fruit and vegetables and/or a balanced diet are associated with higher life satisfaction. The review provides evidence for policymakers, healthcare workers, caregivers, and society to encourage healthy behaviours that foster healthy ageing. Future studies should use standardised instruments to assess health behaviours and life satisfaction, facilitating cross-study comparisons and the meta-synthesis of research findings.

Incarcerated individuals experience disproportionately high levels of sedentary behaviour (SB), which increases their risk of physical and mental health problems. Although regular physical activity (PA) can mitigate these risks, correctional settings often present environmental and institutional barriers that limit opportunities for movement. While modifying built environments has shown promise for promoting PA in community settings, limited research has explored these strategies in prisons. This study applied a community science, co-creation approach to identify inmate-informed, context-specific solutions to reduce SB and enhance PA within a prison setting. METHODS: The study was conducted in a Spanish male prison with 26 adult inmates. Based on facility-use records and self-reported activity/sedentary levels, 13 highly active and 13 inactive inmates were purposively selected to capture diverse perspectives. Participants took part in structured workshops using the Our Voice community science framework. With the Our Voice Discovery Tool mobile app, they documented environmental barriers and facilitators to PA through geo-tagged photos and audio or text comments while moving through prison spaces. Data sources included workshop transcripts, facilitator notes, and app-generated digital content, which were analyzed using Braun and Clarke’s codebook thematic approach. Participants then proposed and ranked potential solutions using an Eisenhower Matrix, and these were later refined with input from prison staff and policymakers. RESULTS: Six major themes influencing movement opportunities emerged: (1) activities, (2) spaces, (3) equipment and materials, (4) staff and support, (5) regulation-related limitations, and (6) scheduling. In total, 39 inmate-generated strategies were identified, 31 of which were rated as high priority. Low-difficulty actions included improved maintenance of activity areas, expanded access to equipment, and more flexible use of existing spaces. Participants emphasized that socially supportive environments were essential to motivation, adherence, and mental well-being. CONCLUSIONS: The study demonstrates the feasibility and value of participatory community science in correctional settings. Involving incarcerated individuals in designing PA solutions generates practical, context-appropriate strategies and supports greater health equity. This approach offers a scalable model for institutions aiming to reduce SB and promote PA through built-environment improvements. </p>","PeriodicalId":50336,"journal":{"name":"International Journal of Behavioral Nutrition and Physical Activity","volume":" ","pages":"12"},"PeriodicalIF":7.1,"publicationDate":"2026-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12908275/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146020508","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}

Physical activity (PA) can attenuate side effects and improve quality of life. However, most cancer survivors fail to meet PA guidelines. Theory-based PA interventions are effective in breast cancer survivors, but scarce. PAC-WOMAN tested the effects of two PA promotion interventions (supervised exercise vs brief counseling) on primary outcomes – PA, sedentary behavior, quality of life –, and secondary outcomes – body composition, fitness, physical function, sleep, body image, depression, psychological well-being, pain, and motivational variables – in women on AI. METHODS: This pragmatic randomized controlled trial included 110 women with stage I-III hormone-receptor-positive breast cancer on AI (56.1 ± 7.6 yr; 28.1 ± 5.9 kg/m2; 23.4 ± 20.1 months on AI), randomized to: 1) brief PA counseling (PAC); 2) structured exercise (ExG); 3) waiting-list control. Primary and secondary outcomes were evaluated with validated instruments at the end of the intervention period. Repeated measures’ Anovas, adjusted for age, AI duration, body mass index and chronic diseases, were conducted. Bonferroni corrections were applied (significance level at p < 0.0083). RESULTS: Significant group-by-time interactions were observed for moderate-vigorous PA (MVPA), exercise motivations and affect, muscle strength and leg endurance (p ≤ 0.008). Objectively measured PA showed no significant effects in either intervention group, except for a near-significant MVPA increase of 107 min/week [95% CI: 4; 209] over time in ExG. Larger improvements were observed in all self-reported PA indicators in ExG, while PAC revealed gains only in light PA and active choices. ExG improved global health status, physical functioning and physiological indicators (e.g., fitness, body composition) over time; PAC enhanced future perspectives, body image functioning, breast symptoms, and other psychological outcomes, with changes in depressive symptoms (-1.4 [-2.4; -0.3]) and life satisfaction (0.8 [0.2; 1.5]) approaching significance. CONCLUSIONS: PAC-WOMAN showed that ExG and PAC yielded distinct benefits for breast cancer survivors on AI. ExG improved total PA, fitness, physical function, physical quality of life, and alleviated pain symptoms. PAC primarily enhanced light PA and psychological outcomes such as body image and life satisfaction. Together, these findings highlight the potential scalability of PAC alongside the robust physical benefits of ExG.

However, existing evidence regarding its effectiveness remains inconsistent. This study aimed to evaluate the effectiveness of CGM in improving physical activity and diet for people with diabetes using both qualitative and quantitative approaches. METHODS: We searched PubMed, Cochrane, Embase, and Web of Science on October 13, 2024 to identify studies utilizing CGM in people of any age with any type of diabetes that reported outcomes related to physical activity and/or diet and were eligible for systematic review. Randomized controlled trials in which CGM was used as the main intervention and whose outcomes could be quantitatively synthesized were included in the meta-analysis. RESULTS: The initial search identified 13,128 records, then 28 studies met the inclusion criteria for the systematic review. Of these, 10 and 8 studies were included in the meta-analysis of physical activity and diet, respectively. Compared with controls, CGM significantly increased daily physical activity time (MD: 16.21 min/day, 95% CI: 10.26 to 22.16; P<0.0001) (low-certainty evidence). In addition, CGM significantly reduced daily caloric intake (-70.81 kcal/day, -132.93 to -8.69; P = 0.03) (low-certainty evidence) and carbohydrate consumption (-19.88 g/day, -27.74 to -12.01; P < 0.00001) (low-certainty evidence) versus controls.

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.

It also explored how resistance training is prescribed through mHealth, and the theoretical frameworks and behavior change techniques (BCTs) employed. 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. Majority of studies included bodyweight exercises, prescribed via videos or pictures, along with text description. Exercise prescription was generally poorly reported across studies. Only 7 studies used a theoretical framework to inform their intervention. All studies incorporated BCTs (17 discrete BCTs used), with a focus on providing instruction and demonstrating behavior. CONCLUSIONS: mHealth is a potentially scalable, effective method of prescribing resistance training. Better reporting of exercise prescription, along with clearer grounding in established theoretical frameworks, is recommended. REVIEW REGISTRATION: The review was prospectively registered with the International Prospective Register of Systematic Reviews (PROSPERO; registration number CRD42025641142). </p>","PeriodicalId":50336,"journal":{"name":"International Journal of Behavioral Nutrition and Physical Activity","volume":" ","pages":"7"},"PeriodicalIF":7.1,"publicationDate":"2025-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12836956/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145811783","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}
