Calorie, sodium intake associated with diabetic retinopathy progression in African Americans

Medscape (1/20, Barclay) reported that, according to a study published in the January issue of the Archives of Ophthalmology, “high caloric and sodium intake appear to be associated with the progression of diabetic retinopathy (DR) among African American patients with type 1 diabetes.” In a study population of “469 individuals at risk for the progression of DR,” researchers found that “baseline total caloric intake was significantly associated with a six-year incidence of vision-threatening DR (either proliferative DR or macular edema [ME]) and of severe hard exudates,” while “high sodium intake at baseline was a significant, independent risk factor for six-year incidence of ME.”
