Background
Obesity is a risk factor for the development of chronic kidney disease (CKD). However, it remains to be fully examined whether fatness is more useful in predicting incident CKD. We aimed this study to determine the association of body fat, body mass index and waist circumference (WC) with subsequent changes in estimated glomerular filtration rate (eGFR) and incident CKD in young- to middle-aged working men.
Methods
We analyzed data from annual health check-up in male workers aged from 20 to 60 years with basal eGFR of 60–90 mL/min/1.73 m2. Cut-off values of parameters and odds ratio (OR) for the incident CKD were calculated by receiver operator characteristics analysis andχ2 test, respectively. We also tested trends of changes in eGFR according to changes in WC in each age decade.
Results
There were 8,015 men participants. During the 5-year follow-up, 11.0% of the participants (N = 878) had developed to incident CKD. When basal WC was greater than 80.0 cm, which was decided by Youden’s Index, there was a significantly higher risk of incident CKD [OR 1.57 (95% confident interval 1.35–1.84)]. Changes in WC over 5 years were significantly related to eGFR decline in young men (< 40 years old) with normal blood pressures and normoglycemia.
Conclusions
These findings suggest that WC > 80.0 cm is a risk factor for incident CKD and strongly associated with a decline in eGFR in the young- to middle-aged working healthy men.
