These trends have coincided with a widely recognized decline in youth mental health, prompting increasingly polarized debate: some attribute the crisis primarily to smartphones and social media, but large-scale analyses suggest more heterogeneous population-level effects. Therefore, this review examines the role of physical activity (PA) in mental health during the online era; considering how different forms of online engagement relate to youth mental health, with regard to both the emerging downsides (through increasing sedentariness) and the potential for harnessing such platforms to improve PA and mental health, together. As a narrative review of an emerging field, we drew on nonsystematic searches of PubMed and Google Scholar alongside author expertise to integrate key findings and identify new directions. Two conclusions emerged. First, whether online time helps or harms depends more on content, context, and user characteristics than screentime, although converging (though still-developing) causal evidence points to displacement of PA, alongside disrupted sleep as a leading mechanism. Second, digital adoption itself has become an opportunity for promoting PA/delivering exercise interventions, online, with growing evidence of benefits for depression, anxiety, and well-being. However, these tools also carry risks, including body surveillance, social comparison, and compulsive exercise. Furthermore, data on online PA interventions in clinical mental health populations is sparse but appear to favor blended approaches. Overall, we argue the coming decade's key challenge is embedding evidence-based PA promotion within young people's online lives.</p>","PeriodicalId":16812,"journal":{"name":"Journal of physical activity & health","volume":" ","pages":"1-11"},"PeriodicalIF":2.6,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149111170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These studies rely heavily on covariate adjustment, yet decisions about which variables to include vary widely. Such decisions have meaningful consequences, including altering estimated effect sizes and their interpretation, and ultimately, modifying our understanding of how physical activity influences health. For example, inclusion of biological intermediates is likely to constitute overadjustment, while the role of co-occurring health behaviors is more conceptually complex. Despite longstanding recognition of overadjustment bias, there remains little consensus regarding which variables should routinely be included in models that use observational data to explore the effect of physical activity on health. In this paper, we discuss key conceptual definitions and frameworks relevant to covariate selection, such as confounding, mediation, and overadjustment, alongside the shift from statistical toward conceptual approaches including causal inference frameworks (eg, directed acyclic graphs). We outline common biological and behavioral pathways linking physical activity to downstream health outcomes, highlighting the challenges of adjusting for biological intermediates, health-status indicators, and co-occurring health behaviors. We draw on empirical illustrations using data from cohort studies in Brazil, the United Kingdom, and the United States to explore how common adjustment strategies influence estimates of the association between physical activity and each of hypertension, type 2 diabetes, and all-cause mortality. The use of directed acyclic graphs highlights where adjustment decisions may be conceptually simple and where they require careful consideration of the underlying causal assumptions. Our findings demonstrate that adjustment decisions meaningfully influence both the magnitude and interpretation of associations in physical activity epidemiology. We conclude by proposing practical recommendations to improve transparency, interpretation, and covariate selection in future observational epidemiological analyses examining how physical activity influences health outcomes.</p>","PeriodicalId":16812,"journal":{"name":"Journal of physical activity & health","volume":" ","pages":"1-11"},"PeriodicalIF":2.6,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149111185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
