A Multi-Center Cross-Sectional Study on Visual Impairment and Depression Among Students — Jiangsu Province, China, 2017–2022

Abstract

What is already known about this topic? China exhibits a significantly high prevalence of myopia compared to other countries globally. Children with vision impairment have been found to engage less in physical activities, achieve lower academic performance, and have increased vulnerability to depression. What is added by this report? During a six-year observational study, a population-level correlation was identified between varying degrees of visual impairment and the presence of depressive symptoms among students. Specifically, individuals with a visual acuity below 4.0 had a significantly higher odds ratio of 1.90 (95% confidence interval: 1.53–2.37) compared to individuals with normal vision (visual acuity ≥5.0). What are the implications for public health practice? This study highlights the importance of holistic health interventions that address both visual and psychological aspects. Understanding common mechanisms and influential factors can guide the development of more impactful public health strategies.
