Albuminuria in people at least 40 years old: effect of alcohol consumption, regular exercise, and cigarette smoking.
We investigated the relation between albuminuria and life-style factors in 5670 people, ages 40 years and over, who participated in a health screening survey of a local workforce. The degree of albuminuria showed piecewise log-linear relationships with alcohol consumption and cigarette smoking, with changes in slope (and 95% confidence interval) corresponding with 5 (2, 8) g of alcohol/day and 10 (6, 14) cigarettes/day. After adjusting for age, gender, ethnicity, and other life-style variables, relative risks (95% confidence interval) of slight albuminuria for people consuming > 32 g of alcohol/day compared with nondrinkers, and for cigarette smokers compared with nonsmokers, were 1.74 (1.02, 2.98) and 1.37 (1.01, 1.88), respectively. However, there was no significant effect of exercise. We conclude that slight albuminuria is significantly associated with cigarette smoking and heavy alcohol consumption, consistent with its role as an index of risk of cardiovascular disease.
