Comparison of the Prevalence of Hypertension between the Children with Hematuria and Healthy Children

Background: Abnormal disposal level of red blood cells in the urine is called hematuria and can be a sign of a serious or benign renal pathology in children. Hematuria, hypertension, and kidney diseases have closely relationship. Given the high prevalence of hypertension in children, the aim of this study was to compare it between children with hematuria and healthy children. Methods: This was a case-control study on 50 children with hematuria and 50 healthy children. Detection of hematuria was performed with urinary analysis and confirmation of diagnosis by microscopic observation. Child's blood pressure and body mass index, and parental pressure were measured accurately by one person. Then, statistical analysis was performed via SPSS software. Results: The frequency of sex (20 men and 30 women, and 21 men and 29 women in case control groups, respectively) was not significantly different between the two groups (P = 0.839), as well as other demographic variables. Children's maximum and minimum blood pressure in the case group (and mmHg) was significantly higher than the control group (88.90 vs. 81.20 and 63.93 vs. 55.86 mmHg, respectively). Significant correlations were seen between maximum blood pressure in children with hematuria with parents' minimum and maximum blood pressure, and children's age. Conclusion: Due to the elevated blood pressure in children with hematuria, child's blood pressure can be named as a risk factor in incidence of hematuria.
