Background Environmental factors may contribute to short sleep duration and irregular bedtime in children.Neighborhood factors and children's sleep duration and bedtime regularity remain a less investigated area.The aim of this study was to investigate the national and state-level proportions of children with short sleep duration and irregular bedtime and their neighborhood predictors.Methods A total of 67,598 children whose parents completed the National Survey of Children's Health in 2019-2020 were included in the analysis.Survey-weighted Poisson regression was used to explore the neighborhood predictors of children's short sleep duration and irregular bedtime.Results The prevalence of short sleep duration and irregular bedtime among children in the United States(US)was 34.6％[95％confidence interval(CI)=33.8％-35.4％]and 16.4％(95％CI=15.6％-17.2％)in 2019-2020,respectively.Safe neigh-borhoods,supportive neighborhoods,and neighborhoods with amenities were found to be protective factors against children's short sleep duration,with risk ratios ranging between 0.92 and 0.94,P＜0.05.Neighborhoods with detracting elements were associated with an increased risk of short sleep duration[risk ratio(RR)=1.06,95％CI=1.00-1.12]and irregular bedtime(RR=1.15,95％CI=1.03-1.28).Child race/ethnicity moderated the relationship between neighborhood with amenities and short sleep duration.Conclusions Insufficient sleep duration and irregular bedtime were highly prevalent among US children.A favorable neigh-borhood environment can decrease children's risk of short sleep duration and irregular bedtime.Improving the neighborhood environment has implications for children's sleep health,especially for children from minority racial/ethnic groups.
