    Abstract:
    Obesity and insulin resistance are directly associated with the presence of microalbuminuria. However, the prospective relationship between abdominal adiposity and the occurrence of micro-albuminuria has been little studied in a non-diabetic population. From the DESIR cohort, we examined whether waist circumference was associated with the incidence of micro-albuminuria at 6 years (D6). The study evaluated 2738 non-diabetic subjects without micro-albuminuria at inclusion who were then followed prospectively. At 6 years, 254 individuals (9.3%) had developed pathological micro-albuminuria (> or =20 mg/l) measured at micturation. In both sexes, the incidence of micro-albuminuria was associated with increased waist circumference and blood pressure, but not with blood glucose levels, lipid parameters or body mass index. Subjects with a higher waist circumference at inclusion were at a higher risk of having micro-albuminuria at 6 years compared to those with a normal waist circumference. Logical regression analysis showed that waist circumference as a continuous value, or greater than 94 cm for males and 88 cm for females, were predictive factors for the incidence of micro-albuminuria, after adjustment for age, hypertension, ACE inhibitor usage, fibrinogen, and blood glucose level. Abdominal adiposity is thus linked in both sexes to the development of microalbuminuria, which underlines the importance of measuring waist circumference when assessing risk factors for renal lesions in non-diabetic hypertensives.
