Body Mass Index and Early Kidney Function Decline in Young Adults: A Longitudinal Analysis of the CARDIA (Coronary Artery Risk Development in Young Adults) Study

As reported by the American Society of Nephrology:

Higher BMI categories were associated with greater declines in kidney function in a 10-year study of 2839 black and white young adults with normal kidney function at baseline. Individuals with a BMI of 25.0 to 29.9 were 1.50 times more likely to experience rapid kidney function decline; those with a BMI between 30.0 and 39.9 were 2.01 times more likely; and those with a BMI of 40.0 or higher were 2.57 times more likely. After age 30, average kidney function was progressively lower with each increment in BMI. The findings are published in the American Journal of Kidney Diseases.
