Addressing indoor environmental exposures is crucial for improving sleep quality in children suffering from chronic cough.
According to a Chinese cross-sectional study, alarming connections between chronic cough in children and various abnormal sleep behaviors have been revealed. Shiyao Xu and researchers found that children (aged 3 to 18 years) with chronic cough were more likely to experience sleep disturbances, with noteworthy links found for recent household decoration, mold exposure, and carpet use.
Indoor conditions greatly affect the quality of sleep in children with chronic cough. Although previous research has identified several influential environmental factors—like pet ownership, pest presence, mattress quality, and exposure to tobacco smoke, this study explicitly intended to assess how these influences relate to sleep behavior in this vulnerable population. Data from children aged 3 to 18 years was collected by using comprehensive questionnaires that evaluated sociodemographic factors, allergies, environmental exposures, and sleep patterns.
The logistic regression models were used to explore the connection between indoor environmental factors and sleep troubles among those with chronic cough. The findings revealed that 15.5% of children in the study experienced chronic cough. Compared to those without chronic coughs, these children were more likely to suffer from additional health issues, including dermatitis (eczema), wheezing, and food allergies. Additionally, a family history of sleep disorders and adenoid hypertrophy (enlarged adenoids) was highly prevalent in this group.
The study identified significant correlations between specific sleep behaviors and chronic cough after adjusting for various confounding factors. For instance, teeth grinding or bruxism was linked to chronic cough, with odds ratios (OR) displaying a notable association (OR=1.04). Furthermore, recent home renovations were found to increase the probability of sleepwalking (OR=1.04), mold exposure was related to bruxism (OR = 1.15), and carpet use was related to conditions like sleep apnea (OR = 1.09, twitching during sleep (OR = 1.13), and headaches in the morning (OR = 1.14).
