[Identification of risk factors for chronic kidney disease among schoolchildren].

Abstract

Aiming at identifying risk factors for chronic kidney disease (CKD) among schoolchildren, a cross-sectional population study was carried out in six municipal schools in Goiânia, Brazil. We investigated: history of birthweight, enuresis, urinary incontinence, mictional urgency, family history of kidney disease, diabetes, arterial hypertension, percentiles of arterial blood pressure, waist circumference and body mass index (BMI). We evaluated 274 children, mean age of 8.06 ± 1.33 years, among which 139 (50.7%) were female. We detected: enuresis in 50 (18.2%); urinary incontinence in 34 (12.4%); mictional urgency in 49 (17.9%); BMI above P85 in 18.8% (45); waist circumference above P90 in 17 (6.9%); arterial blood pressure above P95 in 17 (7.1%). Also, we observed correlation between arterial blood pressure, obesity, and increased waist circumference, (p < 0.05). The study showed high frequency of abnormal voiding habits and increased BMI in this population.
