Methods: Information on eye behavior and eye health of primary and secondary school students in Wuhan was collected by multistage stratified cluster sampling. The latent class analysis (LCA) method was used to analyze students' eye care behavior, and the latent class model (LCM) was built. Results: A total of 6130 students were enrolled in this study, of whom 53.56% were males, aged from 6 to 17 years old, with an average age of 10.33±2.60. The latent class results classified the adolescents' eye care behaviors into bad behaviors, moderate behaviors, and healthy behaviors. The model fitting results were as follows: Akaike Information Criterion (AIC) was 36698.216, Bayesian Information Criterion (BIC) was 36906.565, Adjusted Bayesian Information Criterion (aBIC) was 36808.056, and entropy was 0.838. Compared with the healthy behaviors class, the bad behaviors class was more prevalent in high schools (p=0.003), nondemonstration schools (p=0.001), and most of this group had astigmatism (p=0.002). The moderate behaviors class predominately consisted of females (p=0.001), 15-17 years old (p=0.005, 6~8 years old as the reference), from non-demonstration schools ( p<0.001), and most had myopia (p=0.009). Conclusion: There were differences in basic demographic characteristics, visual acuity development level, and family visual environment among different classes. In the management and intervention of adolescent vision health, we should continue to promote the visual health management of adolescents based on visual monitoring and realize the early intervention and guidance of individuals in bad behaviors class.
