To investigate the relationship between anthropometric parameters and elevated blood pressure in adolescents, we measured blood pressure (BP), height, weight, triceps skinfold (TSF) thickness, waist circumference (WC), and mid-upper-arm circumference (MUAC) in 2,860 student volunteers aged 11-17 years in Kayseri, Turkey. Waist-to-height ratio (WHtR), waist-to-arm-span ratio (WASR), body mass index (BMI), arm-fat area (AFA), and fat percentage (FP) were also calculated. Participants were divided into two groups: hypertensive [systolic blood pressure (SBP) or diastolic blood pressure (DBP) ≥ 95th percentiles, n = 246] and normotensives (SBP or DBP < 95th percentiles, n = 2614). Multiple logistic regression models were produced within these groups for the examined risk factors, and cutoff points were investigated for SBP or DBP ≥ 95th percentiles using receiver operating characteristics (ROC) analysis. BMI, WC, WHtR, WASR, MUAC, and BMI had statistically significant cutoffs among boys. Whereas BMI, WHtR, WASR, WC, MUAC, AFA, and TSF were statistically significant for girls younger than 15, only BMI and WC were statistically significant for participants older than 15. The independent risk factors for elevated BP were determined according to BMI and WC. Although several anthropometric measurements were significant in our participants, BMI and WC were significant among all participants irrespective of age and sex.
