title: Study of blood pressure and blood sugar levels in adolescence and comparison with body mass index.
abstract: BACKGROUND
  Worldwide prevalence of overweight and obesity is increasing and its consequences prompted the WHO to designate obesity as a global epidemic in 2002. Being overweight is a risk factor for significant illness, especially diabetes and hypertension in adult life.
  
  
  OBJECTIVE
  To study the blood pressure and blood sugar levels and lifestyle parameters in adolescence and comparison with body mass index.
  
  
  METHODS
  In a prospective case control study, out of the 1000 screened, a total of 200 adolescents were considered out of which 100 were with high body mass index (BMI) and the other 100 were with normal BMI. Height, weight, BMI, waist hip ratio (WHR), blood pressure (BP), BSL, and associated risk factors like physical activity, fast food consumption, and computer/television watching were measured and screened.
  
  
  RESULTS
  109 (54.5%) males and 91 (45.5%) females were included. Maximum number [90 (45%)] of adolescents screened were in the age group of 17-19 years, while 54 (27%) and 56 (28%) adolescents were in the age group of 10-13 years and 14-16 years, respectively. According to CDC charts 2000, prevalence of overweight was 24% which was double when compared to WHO charts 2007. There was significant difference in prevalence of obesity; according to CDC chart it was 26%, whereas according to WHO chart it was 39%. The difference in blood pressures between cases and controls as per both CDC and WHO charts was found to be statistically significant (P < 0.0001). Positive family history of hypertension has a highly significant correlation (P < 0.001) with BMI. Blood sugar level (BSL) was significantly higher in cases (high BMI) when compared to controls (normal BMI). The comparison of WHR in the study group showed highly significant correlation ( P < 0.0001) between cases and controls. The present study shows highly significant correlation of physical activity ( P < 0.0001) and fast food ( P < 0.05) between cases and controls, whereas there was no significant correlation of computer/television watching ( P > 0.05) with BMI.
  
  
  CONCLUSIONS
  The adolescents seem to have become heavier owing to environmental influences on growth patterns. So, a consideration should be given to shift the cut-offs for overweight and obesity to higher BMI percentiles if recent growth charts are to be followed. Adolescents with a BMI above the 95 th percentile (obese) are most likely to have obesity-related health risks.
