ABSTRACT
A relationship between blood pressure (BP) and obesity has been found in young adults, but no data are available for adolescents in Kuwait. 257 adolescent (11-19 years) participants were categorized into two groups according to their BMI; 48 nonobese (21 males: 43.7% and 27 females: 56.3%) with mean age of 15.61 ± 2.40 years and 209 obese (128 males: 61.25% and 81 females: 38.75%) with mean age of 15.02 ± 2.82 years. The mean BMI was 21.7 ± 2.23 kg/m(2) for the nonobese group and 34.47 ± 4.70 kg/m(3) for the obese group. Most BP measures based on a single screening were significantly higher in the obese group. The prevalence of elevated BP was significantly higher in the obese subjects (nonobese: 13%; obese: 63%; P < 0.0001). In the obese group, there was a significant positive correlation between total sample BMI and all BP measures except the pulse pressure. There was a similar rate of elevated blood pressure between males and females (64% versus 60%; P = 0.66). For both isolated systolic elevated BP and isolated diastolic elevated BP, the prevalences were comparable between the males (systolic: 42%; diastolic: 5%) and females (systolic: 34%; diastolic: 14%). Only systolic BP was positively correlated with BMI in obese adolescent males (Spearman r = 0.18; P < 0.05), with a significant correlation between BMI with diastolic (Spearman r = 0.22; P < 0.05) and mean BP (Spearman r = 0.21; P < 0.05) in females.
