摘要

AIM: To summarize quantitatively the prospective association between physical activity and age-related cataract(ARC) risk.METHODS: Pub Med, Embase, Web of Science, and Cochrane Library were systematically searched for all relevant follow up studies until July 2019. Multivariableadjusted relative risks(RRs) and corresponding 95% confidence intervals(CIs) from individual studies were used to calculate the overall summary estimates. The doseresponse relationship was assessed using generalized least-squares trend estimation.RESULTS: Six prospective cohort studies, involving 19 173 cases in 6.2-12.1 y follow up of 171 620 participants, were included in the analysis. Increased physical activity was significantly associated with reduced risk of ARC by 10%(RR: 0.90;95%CI: 0.81, 0.99, P=0.04). Stratified analysis by assessment method for physical activity suggest that studies using metabolic equivalent(MET) per day tended to report a slightly stronger association with ARC(RR: 0.85;95%CI: 0.81, 0.90, P<0.001) than studies which assessed activity by weekly activity(RR: 0.96;95%CI: 0.89, 1.03, P=0.24). Dose-response analysis indicated that the risk of ARC decreased by 2%(RR: 0.98;95%CI: 0.98, 0.99, P<0.001) for every 6 METs per day increase in activity.CONCLUSION: The findings from this Meta-analysis provide additional evidence that increased physical activity is inversely associated with ARC risk dose-responsively.
