Abstract: Objective To understand the status of infant sleep behavior and sleep problems in Beijing, and to analyze possible influencing factors, in order to provide reference for the promotion of sleep health in infancy. Methods Community health service centers in two townships in 2 districts from urban and suburban areas were selected from June 1st,2021 to August 31st,2021 in Beijing, by using the cluster sampling method.A questionnaire survey was conducted among 894 resident caregivers to collect general information and infant sleep status. Results Totally 55.0% of infants and caregivers shared the same bed,41.1% of them slept in different beds within the same room.The proportion of infants sleeping on their sides and supine was 48.1% and 46.9%, respectively; and 50.5% and 28.7% for milk sleep and being rocked/cuddled to sleep, respectively.The detection rate of infant sleep problems was 65.9%, and the common sleep problems included difficulty in falling asleep(26.0%), night awakening(13.0%), night crying(12.8%) and circadian rhythm disorder (8.9%).Multivariate analysis showed that circadian rhythm disorder (OR=2.479,95%CI:1.341 - 4.584) and night awakening (OR=3.097,95%CI:1.873 - 5.122) were risk factors for night crying, while infants with fewer (OR=0.237, 95%CI:0.087 - 0.646), few sleep problems(OR=0.190, 95%CI: 0.072 - 0.499) and without sleep problems(OR=0.112, 95%CI: 0.042 - 0.294) were protective factors for night crying. Conclusions Infants in Beijing mainly sleep with bed-sharing, milking and cuddling,with high prevalence of sleep problems.Sleep rhythm disorder may increase the incidence of night crying, so it is necessary to strengthen the education and guidance of infant sleep health for parents.
