Objectives: Hypertension has become common in children and generally remains undiagnosed and untreated.
The present study aims to find the prevalence of high blood pressure (BP) and examines the relationship between
body mass index (BMI) and BP among school going children.
Materials and Methods: A cross-sectional study was conducted among 240 school going children aged between
10 years and 17 years of Udaipur district of Rajasthan. Data were collected using interview schedules and
somatometric measurements were taken based on standardized protocols established by the International Society
for the Advancement of Kinanthropometry. Data were analyzed using Statistical Package for the Social Sciences
software version 20. Hypertension is considered when BP (systolic BP [SBP] and/or diastolic BP [DBP]) level
is ≥95th percentile for height, age, and sex according to the Fourth Report on the Diagnosis, Evaluation, and
Treatment of High BP in Children and Adolescents (2004).
Results: It was found that 49% children were underweight, 3% were overweight, and 2% were obese. Hypertension
was seen in 39 (16.2%) children (5.4% systolic hypertension, 5.8% diastolic hypertension, and 5% both systolic
and diastolic hypertension). Children who were overweight/obese were more likely to have hypertension than
those who were normal or underweight.
Conclusion: The findings of the present study indicate that BMI is a crucial factor affecting BP levels. Simple
measurements of body weight and height to determine BMI as a routine assessment in schools would help in
controlling BP levels in children that might cause adulthood morbidity and mortality due to hypertension.
