Co-sleeping is associated with disturbance of the natural sleep pattern, including sleep fragmentation and daytime sleepiness. Nocturnal enuresis (NE) or bed-wetting, although benign, is a significant cause of distress to affected children and their caregiver(s). This study investigated the relationship between co-sleeping and NE in primary school children from China.


Data from a previous sleep study of primary school children from 8 cities across China were analyzed. Multivariable regression analysis was performed to assess the relationship between co-sleeping and NE while controlling for a number of confounding factors. The prevalence of NE in co-sleeping and non–co-sleeping children in different age groups was evaluated.


The prevalence of co-sleeping and NE in children aged 5 to 12 years was 22.8% and 4.6%, respectively. Co-sleeping was associated with a higher prevalence of NE in primary school age children (odds ratio [OR], 1.50; 95% confidence interval [CI], 1.27–1.77; p < .001) after adjusting for confounding factors. The differences in the prevalence of NE between co-sleepers and non–co-sleepers were significant in the 9-year age group (OR, 1.49; 95% CI, 1.06–2.11; p = .025) and 11- to 12-year age group (OR, 3.16; 95% CI, 2.19–4.57; p < .001).


Co-sleeping may increase the risk of NE in primary school children, particularly in those aged 11 to 12 years.
