Background: Hypertension (HTN) is the common and potent universal contributor to cardiovascular mortality. There are not many studies done about the prevalence of HTN in rural school children. Objectives: The present study was done in school children to know the occurrence/prevalence of HTN and to study the relation of HTN with age, sex, BMI & family history. Study Design: It is a cross sectional study done in randomly selected rural school children in the age group of 6-16 yrs. The study sample includes apparently healthy 1000 children. For each child, BMI was calculated & 3 BP recordings were taken. Results: In the present study, prevalence of systolic HTN was 2.7% in males & 1.5% in females with overall 1.5%. Prevalence of obesity was 6%. 6.7% obese and 13.3% overweight children were hypertensive. Out of 20 hypertensive children only 14(70%) had family history of HTN present. Conclusion: HTN is a major risk factor for cardiovascular & cerebrovascular disease. In the present study prevalence of HTN was 2% with male preponderance (2.7:1.5). Obesity is an important risk factor for cardiovascular complications. In the present study prevalence of HTN was 6.7% in obese and 13.3%in over weight school children.
