DIETARY NUTRIENT INTAKES AND SLIGHT ALBUMINURIA IN PEOPLE AT LEAST 40YEARS OLD

We studied the relation between diet and slight albuminuria in 5416 pe ople, ages 40 years and over, who participated in a health screening s urvey of a local workforce. Degree of albuminuria showed log-linear un ivariate relations with dietary protein, cholesterol, and sodium intak es, and negative log-linear univariate relations with dietary fiber an d polyunsaturated to saturated fat (P/S) ratio. After adjusting for ag e, gender, and ethnicity, the relative risk (95% confidence interval) for slight albuminuria was significantly increased in people reporting dietary cholesterol consumption >226 mg/day compared with people repo rting consumption less-than-or-equal-to 226 mg/day [1.32 (1.02,1.70)], and significantly reduced in people reporting dietary fiber consumpti on >26 g/day compared with people reporting consumption less-than-or-e qual-to 26 g/day [0.74 (0.58, 0.95)]. There was no significant effect of dietary protein, P/S ratio, or salt intake. We conclude that risk o f slight albuminuria is increased by consumption of dietary cholestero l and reduced by consumption of dietary fiber.
