Exposure-response association between outdoor activity time and myopia risk in Chinese children and adolescents: a systematic review and meta-analysis

JDJin DaiJWJianjun WangYBYong-Hong Bao

Key Points

  • This research aims to assess the relationship between outdoor activity time and the risk of myopia in Chinese children and adolescents.
  • Conducted a systematic review of existing literature
  • Performed a meta-analysis to evaluate data
  • Focused on studies assessing outdoor activity and myopia risk
  • Found that greater outdoor activity correlates with reduced myopia risk
  • Identified approximately two hours of daily outdoor activity as beneficial

Abstract

Greater outdoor activity time is associated with lower myopia risk among Chinese children and adolescents. An approximate daily exposure of around two hours appears to represent a pragmatic benchmark under current educational conditions.
