title: Association of body mass index and waist circumference with hypertension among school children in the age group of 5-16 years belonging to lower income group and middle income group in National Capital Territory of Delhi.
abstract: OBJECTIVE
  Hypertension is one of the most common diseases world-wide and the prevalence in school-aged children appears to be increasing perhaps as a result of increased prevalence of obesity. Thus, the present study was planned to establish an association between body mass index (BMI) and waist circumference (WC) with hypertension amongst school children in the age group of 5-16 years belonging to lower income group (LIG) and middle income group (MIG) in National Capital Territory of Delhi.
  
  
  METHODS
  Population proportionate to size methodology was adopted to select 30 clusters/schools in each LIG and MIG category. About 170 children from each school were selected randomly with the help of random number tables. Anthropometric measurements of weight, height and WC and blood pressure measurements were taken by using standard methodology.
  
  
  RESULTS
  The prevalence of high systolic blood pressure (SBP) in LIG and MIG school population was 2.8% and 4.1% respectively. Similarly, the prevalence of high diastolic blood pressure (DBP) in LIG and MIG school population was 2.7% and 4.2%, respectively. Statistical positive correlation was observed between BMI and WC with SBP and DBP. Thus, it can be inferred that children with high WC and BMI are more likely to have hypertension.
