title: Increase in body mass index, waist circumference and waist-to-height ratio is associated with high blood pressure in children and adolescents in China.
abstract: This study compared the association between blood pressure (BP) and obesity in 1145 Chinese children and adolescents (608 males, 537 females) using data from the 2006 China Health and Nutrition Survey. Obesity was diagnosed by body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WHtR). Analysis of variance was used to analyse the difference in BP among different subgroups. Odds ratios (OR) were calculated and multivariate logistic regression analysis was carried out. The prevalence of high systolic and diastolic BP increased directly with corresponding increments in BMI, WC and WHtR, although the prevalence and OR of high BP were higher when increased BMI was combined with WC (OR 3.39; 95% confidence interval [CI] 1.79, 6.41) or WHtR (OR 3.28; 95% CI 1.71, 6.30). In conclusion, increased BMI, WC and WHtR were directly associated with high BP in Chinese children and adolescents.
