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.

[Mental health status of primary school students during the coronavirus disease 2019 epidemic and its influencing factors].

OBJECTIVE: To study the mental health status of primary school students and the factors influencing the mental health status during the coronavirus disease 2019 (COVID-19) epidemic. METHODS: Online questionnaire surveys were conducted among 3 600 primary school students aged 6-12 years in Jilin Province, China in April, 2020 (during the epidemic) and 3 089 primary school students in September, 2020 (during the regular epidemic prevention and control). The general information and the data related to the Mental Health Scale for Child and Adolescent were collected by the questionnaire surveys. The multivariate logistic regression analysis was used to evaluate the factors influencing the mental health status of the students during the epidemic. RESULTS: The students during the epidemic had a significantly poorer mental health status in the emotional experience and volitional behavior than those during the regular epidemic prevention and control (P < 0.05). The multivariate logistic regression analysis showed the risk of psychological problems of the students decreased with age (OR=0.895). The girls were at a higher risk of psychological problems than boys (OR=1.453). The students with father's and mother's charater between irritability and gentle were at a lower risk of psychological problems (OR=0.496 and 0.470 respectively). The students from a family with a parental education style of a combination of encouraging and scolding were at a lower risk of psychological problems (OR=0.263). The students from a single-parent family or an extended family were at a higher risk of psychological problems (OR=2.995 and 3.446 respectively). CONCLUSIONS: The COVID-19 epidemic has a certain impact on emotional experience and volitional behavior of primary school students. During the epidemic, particular attention should be paid to the mental health of primary school students, especially girls, younger students, and students from single-parent families, extended families or families with impatient parents and improper parental education.
