title: [Relationship between body fat and creatinine clearence in adults with and without diabetes mellitus].
abstract: BACKGROUND
  Obesity is a risk factor for renal damage. This study aimed to determine the relationship between body fat percent and creatinine clearance in adult patients with and without type 2 diabetes mellitus (T2DM).
  
  
  METHODS
  An observational prospective cross-correlation study was carried out among adults with and without T2DM between 18 and 60 years of age. It was determined the time of evolution with T2DM, as well as fat percentage (FP), body mass index (BMI), creatinine clearance (Cockroft-Gault [CrCCG]), glycemia and micro/macroalbuminuria. The correlation between CrCCG and FP was determined by Spearman's test.
  
  
  RESULTS
  174 subjects were included in this study. Obesity by BMI and FP in subjects with and without T2DM was similar. Of the studied subjects, 12.6 % didn't have kidney damage and 50.7 % had increased risk of renal disease; the frequencies for stages 1-4 of kidney damage were 12.0, 20.1, 4.0 and 0.6 %, respectively. Spearman's test showed a direct relationship between FP and CrCCG, higher in diabetics (r = 0.418, p < 0.0001) than in non-diabetics (p = 0.327, p < 0.0001).
  
  
  CONCLUSIONS
  The FP was correlated directly with the CrCCG in subjects with and without T2DM; therefore, we can conclude that the greater the kidney damage, the smaller the fat porcentage in the study sample.
