Background: The obesity in children is reaching at unprecedented levels secondary to two remarkable changes in the habits of millennial children: consumption of high calorieand highly processed food (with higher salt content). Aim: To determine the prevalence of asymptomatic hypertension and study the relationship of blood pressure with biophysical variables- age, gender, weight, height, BMI, and waist-to-height ratio among children aged 6-15 years. Material and Methods: This was a single-centre, field-based, cross-sectional, observational study conducted at urban areas of Bhopal over a period of 18 months among a total of 351 children aged 6-15 years. Results:Among the 351 participants: 11.68% were categorized to have elevated BP and 9.69% children had stage-I hypertension. Among 168 girls, 7.7% had elevated BP and hypertension respectively and among 183 boys; 14.7% and 11.5% children had elevated BP and hypertension respectively (p=0.416). The difference in the BMI categories among the children with normal BP and elevated BP or hypertension was statistically significant (p< 0.0001).Most children with elevated BP and hypertension had a high waist to height ratio(p = 0.0012). There was a linear relationship between the weight of the children and blood pressure. Conclusion: One in five children had blood pressure that was high for their age. Elevated blood pressure were substantially more common among overweight and obese children. The blood pressure especially among obese children should be measured on a compulsory basis at least once every year.
