To analyze the association between different sleep statuses and overweight/obesity among primary school students, so as to provide a basis for the development of childhood overweight and obesity prevention and control strategies.
In November 2023, a total of 3 391 primary school students of grade 1-6 from seven schools in Baoan District, Shenzhen, were surveyed by questionnaires and physical examinations by using multi-stage cluster sampling. The Logistic regression analysis was used to explore the association between primary school students' sleep status and overweight/obesity.
The detection rate of overweight/obesity in primary school students was 22.59%, the detection rate of overweight/obesity in boys (27.04%) was higher than that in girls (17.44%), the only child (25.81%) had higher rates than non-only child (21.76%), and the differences were statistically significant (χ2=51.48, 5.98, P<0.05). Multivariate Logistic regression analysis showed that, after controlling for confounders, primary school students' weekend nighttime sleep duration (OR=0.83, 95%CI=0.75-0.91), weekly average nighttime sleep duration (OR=0.76, 95%CI=0.64-0.89), and weekend compensated sleep duration (OR=0.89, 95%CI=0.81-0.97) were negatively associated with the risk of developing overweight/obesity (P<0.05). Compared with to primary school students with school days nap durations<0.5 h, those whose napped for 0.5-<1 h and ≥1 h on school days had a 20% (OR=1.20, 95%CI=1.02-1.42) and 37% (OR=1.37, 95%CI=1.02-1.83) increased risk of overweight/obesity, respectively (P<0.05).
Increasing weekend nighttime sleep duration, average weekly nighttime sleep duration, and weekend compensatory sleep duration can reduce the risk of overweight and obesity in primary school students. School days nap duration is a risk factor for overweight/obesity among primary school students.
