Prevalence of arterial hypertension and anthropometrical predictors of elevated blood pressure in 14 years old adolescents
Journal Title: Postępy Nauk Medycznych - Year 2015, Vol 28, Issue 11
Abstract
Introduction. Prevalence of arterial hypertension (AH) based on blood pressure (BP)measurements done on three occasions and assessment of BMI and waist circumference(WC) as predictors of AH was assessed in few studies.Aim. To assess prevalence of AH and to estimate specificity and sensitivity of BMI andWC in predicting BP status in 416 adolescents (210 males) in mean age 14.5 ± 0.9 yrs.Material and methods. Recruited subjects represented 90% of local population in thisage. BP was measured with auscultatory sphygmomanometer on three different occasions.Results. Prehypertension was diagnosed in 9% of boys and 7.7% of girls, and AH in12.3% (11.4% in boys, 13.1% in girls). Stage 1 AH was found in 8.6% of boys and 9.7%of girls and stage 2 AH in 2.9% and 3.4% of boys and girls, respectively. 95th percentileof WC had better sensitivity and specificity over 95th percentile of BMI (0.57 and 0.95vs 0.25 and 0.96, respectively) in predicting prehypertension and AH. For diagnosis ofstage 2 AH 85th percentiles of WC and BMI had sensitivity and specificity of 0.67 and 0.78vs 0.62 and 0.80, respectively. The same was found when only non-obese children wereincluded to analysis.Conclusions. The prevalence of AH among 14 years old adolescents was 12.3% andof prehypertension was 8.4%. Both BMI and WC predicted prehypertension and AH butWC had better specificity and sensitivity in predicting stage 2 AH both in general populationand among non-obese children.
