Background: Engagement in muscle strengthening activities (MSA) is a neglected health behavior that can have substantive health benefits. Objective: We evaluated the specific association between MSA and retinopathy among a national sample of the broader U.S. adult population, which has yet to be investigated in the literature. Results: Compared to those with no retinopathy, those who engaged in MSA had a 36% (OR=0.64; 95% CI: 0.49-0.85; P=0.004) reduced odds of having mild retinopathy. MSA was not statistically significantly associated with reduced odds of moderate-to-severe retinopathy (OR=0.85; 95% CI: 0.13-5.32; P=0.85). Conclusion: Promotion of MSA is of major public health interest.
