Study on Relationship between Waist Circumference and Blood Pressure among School-Going Adolescents
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2018, Vol 6, Issue 1
Abstract
Background: Hypertension is on the raise among schoolchildren. Overweight and obesity, especially in childhood and adolescents, play an important role in the development of insulin resistance, diabetes mellitus, and hypertension. Obesity indicators such as body mass index (BMI), waist circumference (WC), and waist-to-height ratio play an important role in predicting children with high blood pressure (BP). Aim and Objective: The aim is to study the relationship between WC and BP among school-going adolescents and to examine the utility of WC as an indicator of elevated BP compared to BMI. Methodology: A total of 1392 school-going children were included in the study. Their height, weight, WC, and BP were recorded. BMI was calculated. Results: In this cross-sectional study carried out on 1392 adolescents in Madurai, the incidence of pre-hypertension and hypertension was 3.4% and 1.8%, respectively. Nearly 6% were overweight and 3% were obese. About 6.6% of the children had increased WC. Prediction of pre-hypertension and hypertension among children was found to be statistically significant with sensitivity: 90.41%, specificity: 98.03%, ppv: 71.74%, and npv: 99.46%. Prediction of children with high BP by BMI was also found to be statistically significant with sensitivity: 89.04%, specificity: 95%, ppv: 49.62%, and npv: 99.37%. Conclusion: Obesity indicators such as WC and BMI because of its ease of measurement can be used as a screening tool to identify children with high BP.
