    • Abstract:
      Background: Indoor environmental factors, such as pet ownership, presence of cockroaches, mattress quality, fuel usage (gas or electricity), use of biomass for cooking and heating, exposure to tobacco smoke or household molds can significantly affect the sleep quality of children with chronic cough. However, data regarding the effects of indoor environmental conditions on sleep in this population are limited. This study aimed to assess the prevalence of abnormal sleep behaviors and to establish associations between indoor environmental factors and sleep behaviors among children with chronic cough in Wuxi, China.
      Methods: A cross-sectional design was employed in this study, involving children aged 3-18 years. Data on sociodemographic factors, allergies, home environmental exposures, and sleep characteristics of the participants were collected using paper-based questionnaires. The association between indoor environmental factors and sleep behaviors in children with chronic cough was analyzed using logistic regression models.
      Results: The findings demonstrated that the prevalence of chronic cough among children in Wuxi was 15.50%. The chronic cough group exhibited a significantly higher incidence of eczema, wheezing, rhinitis, food allergy, and nasosinusitis than the non-chronic cough group. In addition, children with chronic cough also tended to have a family history of sleep disorders and adenoid hypertrophy (P < 0.01). After adjusting for confounding factors, a significant association was observed between bruxism (teeth grinding) and chronic cough (sometimes: odds ratio [OR] = 1.04; confidence interval [CI] = 1.01-1.08; always: OR = 1.11; CI = 1.04-1.19; P < 0.01). Among children with chronic cough, recent home decoration was associated with sleepwalking (OR = 1.04; CI = 1.00-1.07; P < 0.05), mold exposure was associated with bruxism (OR = 1.15; CI = 1.0-1.31; P < 0.05), and carpet use at home was associated with apnea (OR = 1.09; CI = 1.02-1.17; P < 0.05), twitching during sleep (OR = 1.13; CI = 1.00-1.27; P < 0.01) and morning headache (OR = 1.14; CI = 1.05-1.23; P < 0.01).
      Conclusion: Children with chronic cough are more prone to some abnormal sleep behaviors than children without chronic cough. Household decoration within a year, household mold exposure, and carpet use were all significantly positively associated with abnormal sleep behaviors in children with chronic cough. Our study provides novel insights into the impact of the indoor environment on children's sleep and the occurrence of chronic cough, offering guidance for tailored health promotion programs for families.
