A questioner was filled by health professionals at ambulatory pediatric clinic followed by waist-hip circumference, height, weight, and blood pressure measurement. Diastolic blood pressure (DBP) and systolic blood pressure (SBP) were adjusted to gender, height, and age. World Health Organization growth standards were used to calculate BMI z-scores.Results: The mean age of subjects was 10.1 years. Body mass index increased SBP by 1.722 mmHg (p=0.001), and DBP by 0.901 mmHg (p=0.006) in boys, and 0.969 mmHg (p=0.036), and DBP by 0.704 mmHg (p=0.045) in girls. Waist hip ratio showed significant difference p=0.041, (p=0.0001) between male and female. Of the baseline characteristics, age >11 years showed significant difference. Symptomatic manifestation of high blood pressure, family history of hypertension, level of activity, income level and post-secondary education in parents, did not show any significant results.Conclusion: Elevated BMI is associated with significantly increased diastolic and systolic blood pressure in obese children, especially in children older than 11 years.
