Sedentary behaviour (sitting time) has becoming a very popular topic for research and translation since early studies on TV viewing in children the 1980s. The most studied area sedentary health outcomes been adiposity young people. However, literature is replete with inconsistencies. We conducted systematic review of reviews meta-analyses to provide comprehensive analysis evidence state-of-the-art synthesis whether behaviours are associated people, what extent any association can be considered ‘causal’. Searches yielded 29 over 450 separate papers. analysed results by observational (cross-sectional longitudinal) intervention designs. Small associations were reported screen time from cross-sectional evidence, but less consistent longitudinal studies. Studies using objective accelerometer measures null associations. Most assessed BMI/BMI-z. Interventions reduce produced modest effects weight status adiposity.

Analysis causality guided classic Bradford Hill criteria concluded that there no causal between youth, although small dose-response exists. Associations adolescents little this causal. This remains complex field different exposure outcome But claims ‘clear’ certainly causality, premature or misguided.

Background: The coronavirus disease 2019 (COVID-19) pandemic has created challenges that have caused profound changes in health behaviors. This study aimed to explore how COVID-19 is affecting the health-related quality of life (QoL) among Chinese adults. Methods: data behaviors and QoL were collected via online surveys from 2289 adults (mean age = 27.8 ± 12 years) who had been isolated at home for an average 77 days. Results: More than 50% respondents reported their time engaged daily physical activity (PA) decreased, while sedentary behavior (SB) increased compared with before lockdown. Only 20% engaging moderate-to-vigorous PA, 23% changed diets be healthier, 30% consuming more vegetables, fruits, milk products home-isolation. During home-isolation, 75.2% rated sleep as very good, 65% they satisfied QoL. Sleep mediated relationship between PA Conclusion: two-to-three-month home-isolation mixed effects on adult China. participants found focused eating patterns, which a positive influence However, people should encouraged exercise limited space maintain generally healthy lifestyle during prolonged quarantine.

To systematically review and meta-analyze the associations between sleep disturbances suicidal ideation, plans, attempts in adolescents explore potential moderators of these associations. Embase, PubMed, ProQuest, China Knowledge Resource Integrated Database were searched from their inception dates to October 19, 2018. We selected cross-sectional, prospective, or retrospective studies without time language restrictions. Nine cross-sectional studies, four prospective one report that, respectively, involved 37 536, 9295, 80 included meta-analysis. Cross-sectional analyses revealed that with at higher risks (pooled odds ratios [ORs] = 2.35, 1.58, 1.92) than those disturbances. Prospective reports indicated significantly predicted risk ideation but not suicide ORs 1.79 1.98, 95% confidence intervals 1.36–2.36 0.62–6.29, respectively). The study did support association attempts. Depression moderate adolescents. Adolescents insomnia complaints had a other complaints.
