<p><strong>Objective: </strong>To compare and evaluate the renal profile of elderly and younger diabetics.</p><p><strong>Methods: </strong>This cross sectional study was conducted in a tertiary care teaching hospital. Patients with type-2-diabetes were grouped into elderly (age≥60years) and younger diabetics. Patients' demographics, duration of diabetes and serum creatinine were recorded. Cockcroft-Gault formula was used to calculate creatinine clearance (Clcr). Statistical analysis was done

... ng Students"t' test and Pearson's correlation. Regression analysis to adjust for covariables was done wherever required.</p><p><strong>Results: </strong>A total of 477 diabetics were included (elderly n=320, young n=157). Body mass index (BMI) was significantly lower (p=0.003) and duration of diabetes was significantly longer (p=0.001) among elderly. Significant difference was noted in serum creatinine (1.06±0.32 vs 0.95±0.29 mg/dl; p=0.0002) and Clcr (57.82±17.41 vs 88.07±24.60 ml/min; p=0.001) between elderly and younger diabetics. Only 4.7% of elderly, whereas 47.8% of young had normal Clcr. Clcr showed a negative correlation with age in elderly (r=-0.389, p&lt;0.001) and young (r=-0.396, p&lt;0.001) and positive correlation with BMI in elderly (r=0.401, p&lt;0.001) and young(r=0.337, p&lt;0.001). Regression analysis of Clcr in elderly and young showed a positive correlation for BMI and inverse relationship for age and duration of diabetes mellitus.</p><p><strong>Conclusion: </strong>Almost 95% of the elderly and 50% of younger diabetics had impaired creatinine clearance. Renal impairment was concealed in most of them since mean serum creatinine was 1 mg/dl. Indian elderly diabetics should be considered renally impaired and drugs for all conditions need adjustment for creatinine clearance.</p>
