Abstract
ObjectivesTo assess the urinary excretion of micronutrients in diabetic patients and control subjects, and to correlate it with glycosuria.MethodsWe evaluated control subjects and diabetic patients regarding food intake by 24‐h food record and 24‐hour urine collection; anthropometry (weight, height and waist circumference), and urinary loss of micronutrients and glucose were determined. The groups were compared using the nonparametric Mann‐Whitney tests (* p <0.05). The study was approved by the Research Ethics HCFMRP/USP (Case 6228/2009).Results9 diabetics volunteers participated in the study (52 ± 14 years, BMI 30 ± 11 kg/m2 and CA 99 ± 25 cm) and 9 control subjects (51 ± 16 years, BMI 26 ± 5 kg/m2 and AC 90 ± 13 cm). Various nutritional inadequacies were observed in both groups, with no relation to the urinary loss of nutrients. There was a higher iron excretion in diabetic group and the control group, magnesium. The urinary iron (R = 0.49) and nitrogen (R = 0.74) correlated significantly with glycosuria.Conclusionglycosuria was not a risk factor for urinary loss of nutrients in the present study.
