Abstract

Objective To explore the association of sleep time and screen time with overweight and obesity, and their interaction on overweight and obesity among primary school students, so as to provide the scientific basis for the prevention and control of overweight and obesity among primary school students. Methods From 2022 to 2023, a random cluster sampling method was used to select 1 102 students from grades 2 - 6 of three primary schools in Shiyan City as the study subjects. General demographic characteristics, sleep time, screen time, dietary habits and physical activity time were collected by questionnaire. The height and weight of the students were obtained by on-site physical examination. Multivariate Logistic regression was used for association analysis, and additive and multiplicative models were used for interaction analysis. Results The prevalence of overweight and obesity among primary school students in Shiyan City was 25.8% (284/1 102), the average sleep time of 868 (78.8%) primary school students was <10 hours per day, and the average screen time of 237 (21.5%) primary school students was ≥2 hours per day. There were significant differences in the prevalence of overweight and obesity among students of different genders, sleep time and screen time (χ²=22.381, 5.804, 16.081, P<0.05). Sleep time <10 hours per day (OR=1.524, 95%CI: 1.052 - 2.209) and screen time ≥2 hours per day (OR=1.839, 95%CI: 1.325 - 2.553) were risk factors for overweight and obesity in primary school students. The risk of overweight and obesity in primary students who sleep time <10 hours per day and screen time ≥2 hours per day was 1.762 times higher than those who sleep time≥10 hours per day and screen time <2 hours per day(OR=2.762, 95%CI: 1.698 - 4.495). There was no additive or multiplicative interaction between sleep time and screen time on overweight and obesity among primary school students. Conclusions There is a significant association of daily sleep duration and screen time with overweight and obesity among primary school students. Therefore, future interventions should focus on sleep duration and screen time, fostering active and healthy lifestyles to reduce the risk of overweight and obesity.
