Abstract
BACKGROUND: Myopia and mental disorders share common environmental and behavioral risk factors. Previous studies have been inconsistent regarding the association between them, this systematic review and meta-analysis aims to explore the association between myopia and mental disorders. METHODS: Databases, including PubMed, Web of Science, Wiley online library, and Cochrane Library were searched for eligible publications from January 2000 to July 2024. Studies assessing the relationship between myopia and any one of the mental disorders were identified. Pooled odds ratios (ORs) and their corresponding 95% confidence intervals (95% CIs) were estimated using random-effects models. RESULTS: We identified 15 articles (two cohort studies and 13 cross-sectional studies) examining the impact of myopia on mental disorders, involving 2,841,653 participants from seven countries. Pooled results indicated that myopia was significantly associated with an increased risk of mental disorders (OR = 1.41, 95% CI: 1.23, 1.59). Besides, a significant relationship was observed between the mental disorders and myopia (OR = 1.15, 95% CI: 1.01, 1.29) based on eight articles, including 1,942,855 participants from five countries. Subgroup analyses showed that the association of myopia with both anxiety and depression was significant, with ORs of 1.49 and 1.33, respectively. CONCLUSIONS: Myopia and mental disorders may influence each other, with each condition potentially exacerbating the risk of the other. These findings help to explore the possible interplay between mental disorders and myopia.
