title: Modifiable dietary habits and their relation to metabolic abnormalities in men and women with human immunodeficiency virus infection and fat redistribution.
abstract: We assessed the relationship between dietary intake, body composition, and metabolic parameters in 85 consecutive human immunodeficiency virus (HIV)-infected patients with fat redistribution. Dietary history and values for fasting glucose, insulin, lipids, and oral glucose tolerance were obtained for 62 men and 23 women with HIV infection and fat redistribution (mean age +/- standard error of the mean [SEM], 43.5+/-0.9 years; mean body mass index [BMI] +/- SEM, 26.3+/-0.5 kg/m2). A multivariate regression analysis was used to predict insulin area under the curve (AUC) following the oral glucose tolerance test; this included age, sex, BMI, waist-to-hip ratio, kilocalories, duration of protease inhibitor (PI) use, fat redistribution pattern, alcohol intake, dietary fiber intake, and polyunsaturated-to-saturated (P:S) fat ratio. Only age (P=.004), PI use duration (P=.02), and P:S fat ratio (P=.003) were positively associated with insulin AUC. Dietary fiber intake was inversely associated with the insulin AUC (P=.001). In a similar analysis, alcohol consumption was a significant positive predictor of low-density lipoprotein cholesterol. Polyunsaturated fats, fiber, and alcohol are strongly associated with insulin resistance and hyperlipidemia in this population and may be important targets for dietary modification.
