[Cross-sectional study on the sleep status and risk factors for sleep problems in infants and young children in Jilin Province].

Objectives: To explore the sleep status and risk factors for sleep problems in infants and young children in Jilin Province.
Methods: A total of 1 080 healthy infants and young children aged 0-3 years from eight prefecture-level cities and one autonomous prefecture in Jilin Province were selected as subjects. A self-designed questionnaire was used to collect the general information of the subjects, and the Brief Infant Sleep Questionnaire was used to understand the sleep status of the subjects. Multivariate logistic regression analysis was used to analyze the risk factors for sleep problems.
Results: The total detection rate of sleep problems in the infants and young children was 38.24% (413/1 080). The total sleep time in the 4-11 month, 12-24 month, and 25-36 month age groups was higher than the recommended total sleep time ( P <0.05). Multivariate logistic regression analysis showed that full-term birth, higher educational level of the main caregiver, and higher daytime activity intensity were protective factors for sleep problems in the infants and young children ( P <0.05), while lower frequency of vitamin D supplementation, frequent night feeding, and maternal snoring were risk factors for sleep problems ( P <0.05).
Conclusions: The total sleep time of infants and young children over 4 months old in Jilin Province is higher than the recommended total sleep time, but the prevalence rate of sleep problems is higher. The occurrence of sleep problems is related to various factors. Strengthening follow-up on preterm infants, providing education on infant sleep knowledge to primary caregivers, and regularly supplementing with vitamin D can be beneficial in reducing sleep problems in infants and young children.
