Abstract: Objective To analyse the sleep time,the prevalence and the risk factors of sleep disorders in children with allergic diseases of 3~6 years old in Nanjing,and to provide evidence for the prevention and intervention of sleep disorders. Method A total of 1 432 children of 3~6 years old were selected by a stratified cluster sampling method from Nanning city.The parents were surveyed with Children's Sleep Habits Questionnaire. Results The mean of total sleep time of 3~6 years old children were(10.74±0.85)h,remarkably shorter compared with the typical sleep time of Western children of the same age.Sleep times in allergic rhinitis and asthma children were shorter than those of healthy children with significant difference (P<0.05).The incidence of sleep disorder was 52.7%,the incidence of sleep disorders in asthma and allergic rhinitis children were 68.3% and 66.5% respectively. Conclusions The total sleep time of preschool children is relatively less in Nanjing,and the prevalence of sleep disorders is higher compared to the existing data.Allergic diseases could be the risk factor which should pay a great attention.
