Introduction & Aim: Hypertension in adolescents is new concern in recent decades. Increasing cardiovascular
risk factor such as hypertension is related to overweight and obesity among adolescents. Both obesity and
hypertension as important public health challenges are increasing worldwide. An increase in both Body Mass
Index (BMI) and Waist Circumference (WC) is linked to an increased risk of cardiovascular diseases. The
aim of this study was to determine the prevalence of hypertension among the adolescents and investigate its
relationship with overweight and obesity in Mashhad city.
Method: This cross sectional study was conducted among 1189 urban secondary school children who studied
in 10 schools (over ally selected from 501 schools), in both low and high socio-demographic districts of
Mashhad. Students’ blood pressure was measured and categorized according to the standardized technique
described by the American Heart Association (national high blood pressure education program working
group on high blood pressure in children and adolescents).
Results: Prevalence of hypertension was 14.6% in terms of Diastolic Blood (DBP) and 4% in terms of
Systolic Blood (SBP). SBP was more prevalent among males (5.2%), while DBP was more prevalent among
females (15.1%), combined hypertension was doubled in males in comparison with females. In terms of SBP,
about 58% of overweight/obese adolescents were hypertensive. The relationship between BMI and SBP was
statistically significant. Also, 18.8% of central overweight/obese adolescents were hypertensive, while WC was
significantly related to SBP. In terms of DBP about 56.8% of overweight/obese adolescents were hypertensive
and the relationship between BMI and DBP was statistically significant. On the other hand 17.9% of central
overweight/obese adolescents were hypertensive while WC was significantly related to DBP.
Conclusion: Childhood obesity is known as an increasingly health concern in Mashhad. Obesity as leading
cause of pediatric hypertension threatens adolescents’ health and life in this area. So, policies are needed on
its control.
