Dietary Intake of Lutein and Diabetic Retinopathy in the Atherosclerosis Risk in Communities Study (ARIC).

ABSTRACT:

Purpose

We tested the hypothesis that dietary intake of lutein is inversely associated with prevalence of diabetic retinopathy (DR) due to its antioxidant and anti-inflammatory properties and location within the retina.

Methods

We used logistic regression to examine the association between prevalent DR and energy-adjusted lutein intake by quartile (Q) using data collected from 1430 Atherosclerosis Risk in Communities Study (ARIC) participants with diabetes (n = 994 white, n = 508 black). DR was assessed from 45° non-mydriatic retinal photographs of one randomly chosen eye taken at visit 3 (1993-1995). Dietary lutein intake was estimated using a 66-item food frequency questionnaire at visit 1 (1987-1989).

Results

Median estimated daily lutein intake was 1370 µg/1000 kc
