Abstract: Objective To investigate the sleep quality of preschool children who were born preterm in Shanghai,in order to provide reference for improving the sleep quality of premature infants. Methods A total of 8 586 children from 20 kindergartens were selected from May to June 2018 by a random cluster sampling survey,of whom 848 were preterm infants.A questionnaire was applied to investigate basic information about preterm children and their families,sleep habits and sleep disorders about children. Results The incidence of sleep problems was 96.9%,and serious sleep problems rate was 45.9% in 848 preschool children who were born preterm in Shanghai.The most common sleep problems included fear of going to bed (74.3%),snoring (64.9%) and difficulty in falling asleep (56.6%).The incidence of bruxism in boys(54.7%) was significantly higher than that in girls(41.4%)(χ²=14.717,P＜0.001).The average length of sleep was (1.59±0.66) hours in the daytime,(9.19±0.92)hours in the night,and(10.78±1.10)hours in the whole day on average.With the growth of the age,there was a significant decrease in the sleeping time of daytime and whole day(F=15.573,8.086,P＜0.001).With the increase of age,the incidence of night terrors(F=18.745,P＜0.001) and daytime sleepiness(F=1.044,P=0.791)decreased,while the incidence of growth pain increased(F=4.134,P=0.227).The detection rate of sleep insufficiency in preschool children who were born preterm in Shanghai was 16.3%,which gradually increased with age. Conclusions Sleep problems,comorbidity of multiple sleep problems,and sleep insufficiency are prevalent in preschool children who were born preterm in Shanghai.Therefore,the sleep quality of preschool children born preterm in Shanghai can not be ignored,and should be given more concern.
