Men are underrepresented in obesity services, suggesting current weight loss service provision is suboptimal. This systematic review evaluated evidence-based strategies for treating obesity in men. Eight bibliographic databases and four clinical trials’ registers were searched to identify randomized controlled trials (RCTs) of weight loss interventions in men only, with mean/median body mass index of ≥30 kg/m2 (or ≥28 kg/m2 with cardiac risk factors), with a minimum mean/median duration of ≥52 weeks. Interventions included diet, physical activity, behavior change techniques, orlistat, or combinations of these; compared against each other, placebo, or a no intervention control group; in any setting. Twenty-one reports from 14 RCTs were identified. Reducing diets produced more favorable weight loss than physical activity alone (mean weight change after 1 year from a reducing diet compared with an exercise program −3.2 kg, 95% confidence interval −4.8 to −1.6 kg, reported p < .01). The most effective interventions combined reducing diets, exercise, and behavior change techniques (mean difference in weight at 1 year compared with no intervention was −4.9 kg, 95% confidence interval −5.9 to −4.0, reported p < .0001). Group interventions produced favorable weight loss results. The average reported participant retention rate was 78.2%, ranging from 44% to 100% retention, indicating that, once engaged, men remained committed to a weight loss intervention. Weight loss for men is best achieved and maintained with the combination of a reducing diet, increased physical activity, and behavior change techniques. Strategies to increase engagement of men with weight loss services to improve the reach of interventions are needed.

BACKGROUND Children and adolescents increasingly do not meet physical activity (PA) recommendations. Hence, insufficient physical activity (IPA) and sedentary behavior (SB) among children and adolescents are relevant behavior change domains for using individualized mobile health (mHealth) interventions. OBJECTIVE The current review and meta-analysis investigates the effectiveness of mHealth interventions on IPA and SB with a special focus on age level of individualization. METHODS PubMed, Scopus, Web of Science, SPORTDiscus, and Cochrane Library were searched for randomized controlled trials published between January 2000 and March 2021. mHealth interventions for primary prevention in children and adolescents addressing behavior change regarding insufficient PA and SB were included. Included studies were compared for content characteristics as well as methodological quality and summarized narratively. In addition, a meta-analysis with a subsequent exploratory meta-regression examining the moderating effects of age and individualization on overall effectiveness was performed. RESULTS Based on inclusion criteria, 11 of the preliminary 825 identified studies were included for qualitative synthesis and 10 were included for the meta-analysis. Trials included a total of 1515 participants (Age (M, SD) = 11.69 ± 0.788; 65% male; 35% female) with self-reported (n = 4) or device-based measured (n = 7) health data on the duration of SB and physical inactivity (PIA) for an average of 9.3±5.6 weeks. Studies with high levels of individualization decreased insufficient PA levels significantly (d = 0.33; CI = 0.08, 0.58; z = 2.55; p = 0.01), whereas those with low levels of individualization (d = -0.06; CI = -0.32, 0.20; Z = 0.48; p = 0.63), or targeting SB (d = -0.11; CI = -0.01, 0.23; z = 1.73; p = 0.08) indicated no overall significant effect. Heterogeneity of the studies was moderate to low, and significant subgroup differences between trials with high and low levels of individualization (χ2 = 4.04; df = 1; p = 0.04; I² = 75,2%) were found. Age as a moderator variable showed a small effect, but the results were not significant which might have been due to being underpowered. CONCLUSIONS Evidence suggests that mHealth interventions for children and adolescents can foster moderate reductions in PIA but not SB. Moreover, individualized mHealth interventions to reduce PIA seem more effective for adolescents than for children. Although to date only few mHealth studies address inactive and sedentary young people and their quality of evidence is moderate, these findings indicate the relevance of individualization on the one hand and the difficulties in reducing SB using mHealth interventions on the other hand.
