To explore the effects of sleep on subsequent-day physical activity (PA) in children and adolescents, so as to provide a reference for refining PA intervention strategies and further investigating their underlying mechanisms.
Through searching databases including Web of Science Core Collection, PubMed, EBSCOhost, ScienceDirect, Cochrane Library, CNKI, Wanfang and VIP cross-sectional, cohort and experimental studies on sleep and subsequent-day PA among children and adolescents were identified, with the searching period spanning from database inception to June, 2025. Based on the characteristics of the included literature, two sleep variables[sleep duration (SD) and sleep efficiency (SE)] and three physical activity variables[moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), and total physical activity (TPA)] were selected. The relationship between these two types of variables was analyzed for pooled effect sizes using Stata 17.0.
A total of 14 studies were included, with 64.3% published in 2018 or later, involving 11 361 children and adolescents from 17 countries. Meta-analysis results showed that both SD (ES=0.04, 95%CI=0.01-0.07) and SE (ES=0.24, 95%CI=0.01-0.47) were positively correlated with subsequent-day MVPA (both P < 0.05). However, no statistically significant associations were found with LPA (ES=-0.04, 95%CI=-0.13 to 0.06; ES=-0.02, 95%CI=-0.15 to 0.11) or TPA(ES=0.09, 95%CI=-0.02 to 0.20; ES=0.02, 95%CI=-0.03 to 0.06)(all P>0.05). Subgroup analysis revealed that in the "≤6 years" subgroup, SD and SE were positively correlated with TPA (ES=0.22, 95%CI=0.09-0.35) and MVPA (ES=1.19, 95%CI=1.06-1.32), respectively; in the "6-12 years" subgroup, SD was positively correlated with MVPA (ES=0.05, 95%CI=0.02-0.08); in the "≥12 years" subgroup, SE was positively correlated with LPA (ES=0.08, 95%CI=0.00-0.16), while SD was negatively correlated with LPA (ES=-0.23, 95%CI=-0.31 to -0.16) (all P < 0.05).
Adequate SD and good SE can effectively enhance subsequent-day MVPA among children and adolescents, although these sleep effects vary by age group.
