Association between home renovation and sleeping problems among children aged 6 to 18 years: a nationwide survey in China.

BACKGROUND: Although indoor environment has been proposed to be associated with childhood sleep health, to our knowledge no study has investigated the association between home renovation and childhood sleep problems.

METHODS: The study included 186,470 children aged 6 to 18 years from the National Chinese Children Health Study (2012-2018). We measured childhood sleeping problems via the Chinese version of the Sleep Disturbance Scale for Children (C-SDSC). Information on home renovation exposure within recent two years was collected via parent report. We estimated associations between home renovation with various sleeping problems, defined using both continuous and categorized (binary) C-SDSC t-scores, using generalized mixed models. We fitted models with city as a random effect variable, and other covariates as fixed effects.

RESULTS: Out of the overall participants, 89,732 [48%] were exposed to recent home renovations. Compared to the unexposed group, children exposed to home renovations had higher odds of total sleep disorder [odd ratios (OR)=1.3, 95% CI: 1.2-1.4]. Associations varied when we considered different types of home renovation materials. Children exposed to multiple types of home renovation had higher odds of sleeping problems. We observed similar findings when considering continuous C-SDSC t-scores. Additionally, sex and age of children modified the associations of home renovation exposure with some of the sleeping problem subtypes.

CONCLUSIONS: We found that home renovation was associated with higher odds of having sleeping problems, and that they varied when considering the type of renovation, cumulative exposure, sex, and age differences.
