An epidemiological investigation of chronic kidney disease in children with hearing disorder in Hunan province, China

Abstract:

Objective To investigate the prevalence of chronic kidney disease (CKD) among the children with hearing disorder in Hunan province, China. Methods In this cross-sectional study, the multi-stage cluster sampling method was used to select 1 500 children as subjects. Questionnaire surveys, physical examinations, and laboratory examinations were performed on the spot. Results Among the 1 500 children, 1 459 with complete data were included in analysis. Among the 1 459 children, 43 had CKD, with a prevalence rate of 2.95%. The < 7 years group had a significantly higher prevalence rate than the 7-14 years group[5.8% (35/604) vs 0.9% (8/855); P < 0.05]. Among the 43 children with CKD, 31 (72%) had proteinuria, 27(63%) had hematuria, and 11 (26%) had a decreased glomerular filtration rate. Among the 43 children with CKD, stage 1, 2, 3a, 3b, 4, and 5 CKD accounted for 30% (13 cases), 44% (19 cases), 12% (5 cases), 7% (3 cases), 7% (3 cases), and 0% (0 case) respectively. The prevalence rate of CKD increased with the severity of hearing disorder (P < 0.01). Conclusions The prevalence rate of CKD is higher among the children with hearing disorder in Hunan province. Most children have early-stage CKD. CKD is commonly seen in preschool children. Severity of hearing disorder is associated with the prevalence of CKD.
