However, the extent to which these behaviors are prospectively associated with the transition back from overweight\/obesity to a healthy status remains unclear. We examined whether sleep duration and screen time among adolescents with overweight\/obesity are associated with the likelihood of transitioning to a normal body mass index (BMI).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We used data from 3498 U.S. adolescents aged 9\u201311 years with overweight\/obesity (45.1% female), from the Adolescent Brain Cognitive Development (ABCD) Study. Cox proportional hazards models examined the prospective associations of parent-reported sleep duration (9\u201311, 8\u20139, 7\u20138, and &lt;7\u2009h\/day) and screen time (hours\/day) with a shift from overweight\/obesity (BMI percentile \u226585) to a normal (BMI percentile &lt;85) accounting for key covariates including pubertal status.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Over a median 657 days of follow-up, 643 (18.4%) adolescents transitioned from overweight\/obesity to a normal BMI percentile. Compared with those sleeping 9\u201311\u2009h, adolescents sleeping 7\u20138\u2009h were less likely to transition to a normal BMI percentile (hazard ratio [HR]: 0.60, 95% CI 0.44, 0.82), with significant dose-response trend (p for trend\u2009=\u20090.003). The association remained significant in sex-stratified analyses for both females (HR: 0.55, 95% CI 0.30, 0.98) and males (HR: 0.59, 95% CI 0.41, 0.86), with similar significant trend in both groups (p for trend\u2009&lt;0.05). Higher screen time was not associated with transitioning to a normal BMI overall (HR: 0.99, 95% CI 0.96, 1.02) or by sex (females, HR: 1.00, 95% CI 0.95, 1.05; males, HR: 0.99, 95% CI 0.95, 1.02).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Short sleep duration was prospectively associated with a lower likelihood of transitioning to a normal BMI among adolescents with overweight\/obesity.
