To explore the prevalence of comorbidity of myopia and overweight/obesity among junior high school students in Handan and its association with sleep patterns, in order to provide scientific evidence for developing effective prevention measures.
From October to November 2025, a stratified cluster random sampling method was used to select 8 384 junior high school students from 18 counties (cities, districts) in Handan. Participant underwent physical examinations and complete questionnaire. Multivariate Logistic regression model was used to analyze the association between sleep and comorbidity of myopia and overweight/obesity, and restricted cubic spline model was used to clarify the dose-response relationship.
The detection rate of comorbidity of myopia and overweight/obesity among junior high school students in Handan was 16.78%. The median daily sleep duration was 8.42 hours, and the sleep sufficiency rate was 34.03%. Students with light in the sleep environment had a higher risk of comorbidity (OR=1.14, 95%CI:1.01-1.28). Taking the “early to bed and normal wake-up” mode as the reference, junior high school students with “early to bed and early wake-up” mode and “late to bed and normal wake-up” mode had a higher risk of comorbidity (OR=1.27, 95%CI:1.03-1.55; OR=1.33, 95%CI:1.08-1.65). The dose-response relationship between sleep duration and comorbidity risk was an inverted “J” shape. When the sleep duration was longer than 8.1h/d, the comorbidity risk gradually decreased with the extension of sleep duration.
The comorbidity of myopia and overweight/obesity among junior high school students in Handan is a serious issue. Sleep insufficiency is a widespread phenomenon highly associated with an increased risk of comorbidity with myopia and overweight/obesity, indicating that sleep health is a weak link in the current health management of students.
