Physical activity (PA) is inversely associated with diabetic retinopathy (DR) prevalence among adults in the United States.1,2 Sedentary behavior (SB), independent of PA, is also detrimentally associated with risk factors (eg, hemoglobin A1c [HbA1c] level)3 linked with DR incidence.4 To my knowledge, no study has evaluated the association of SB with DR, which was this study’s purpose.

The study design, methods, and covariates used in this cohort study are identical to those of a previous study,2 with the exception that the current study evaluates the association between SB and DR, independent of PA. Data from the 2005 to 2006 National Health and Nutrition Examination Survey were used. All study procedures were approved by the National Center for Health Statistics review board, and written informed consent was obtained from all participants.
