Correction: Associations Between Digital Health Intervention Engagement, Physical Activity, and Sedentary Behavior: Systematic Review and Meta-analysis.

摘要: Background: The effectiveness of digital health interventions is commonly assumed to be related the level user engagement with intervention, including measures both intervention use and users’ subjective experience. However, little known about relationships between physical activity or sedentary behavior. Objective: This study aims describe direction strength association behavior in adults explore whether varies type (ie, experience, activities completed, time, logins). Methods: Four databases were searched from inception December 2019. Grey literature reference lists key systematic reviews journals also searched. Studies eligible for inclusion if they examined a quantitative measure targeting (aged ≥18 years). that purposely sampled recruited individuals on basis pre-existing health-related conditions excluded. In addition, studies excluded individual engaging was not target had non–digital component, targeted multiple behaviors. A random effects meta-analysis vote counting (for included meta-analysis) used address objective 1. Objective 2 association. Results: Overall, 10,653 unique citations identified 375 full texts reviewed. Of these, 19 (26 associations) review, no reporting behavior. 11 indicated small statistically significant positive (based all usage measures) (0.08, 95% CI 0.01-0.14, SD 0.11). Heterogeneity high, 77% variation point estimates explained by between-study heterogeneity. Vote relationship consistently three measures: experience (2 3 associations), completed (5 8 logins (6 10 associations). associations time-based (time spent using intervention) mixed 5 supported hypothesis, inconclusive, 1 rejected hypothesis). Conclusions: findings indicate weak but consistent outcomes. No have across most constructs engagement; however, weak.
