HUBUNGAN ANTARA INDEKS MASA TUBUH DENGAN HIPERTENSI PADA ANAK

Abstract

Background: Prevalence of hypertension in children increased aged 10-19 years. Children with obesity had a relative risk 3,26 to have hypertension. The objective is study to describe the relationship between Body Mass Index (BMI) and hypertension in children aged 12-15 years. Method: The study was an observational study with cross sectional approach in November 2006 and the sample were all of the students in one of the junior high school in Semarang. The blood pressure was measured by using Omron Digital type SEM-1 and classified based on National High Blood Pressure Education Program (NHBPEP). BMI was measured by using Bioelectrical Impedance Analysis (BIA) Omron Karada Scan and classified based on “International Obesity Task Force” based on CDC 2000. The data was analyzed with chi-square. Result: From 1.129 students, we found that 304 children (26,9%) were hypertension and 825 children (73,1%) were not hypertension. Underweight 69 children (6,1%), normalweight 715 children (63,3%), overweight 185 children (16,4%), and obesity 160 children (14,2%). The prevalence risk to hypertension in overweight children was 2,7 (PR= 2,69 95% CI 1,89 – 3,81 P=0,00) and in obesity children was 6,3 (PR= 6,28 95% CI 4,36 – 9,02 P=0,00) greater than normalweight children. Conclusion: There was a significant relationship between increased BMI and hypertension in children. Keyword: Hypertension, Body Mass Index, Children.
