Association of physical activity, sedentary behaviour, sleep duration and myopia in children and adolescents: a systematic review and dose-response meta-analysis

This study aims to examine the dose-response relationships between physical activity (PA), sedentary behavior (SB), sleep duration (SD), and myopia incidence or prevalence, and to identify the daily exposure levels at which these factors significantly elevate the risk of myopia.本研究旨在探讨身体活动（physical activity, PA）、久坐行为（sedentary behavior, SB）、睡眠时长（sleep duration, SD）与近视发生率或患病率之间的剂量-反应关系，并明确上述因素显著升高近视风险的每日暴露水平。
