In a study published online by JAMA Ophthalmology, Paul D. Loprinzi, Ph.D., of the University of Mississippi, University, Miss., evaluated the association of sedentary behavior (SB) with diabetic retinopathy (DR) using data from the 2005 to 2006 National Health and Nutrition Examination Survey.
Sedentary behavior was assessed with an accelerometer, and measured during waking hours in participants with 4 or more days of at least 10 h/d of accelerometer wear time. Activity counts of less than 100/min were used to define SB; activity counts of 100/min or greater were classified as total physical activity (PA).
