title: [Prevalence of hypertension and relationship between hypertension and obesity in children and adolescents in Nanning of Guangxi Province].
abstract: OBJECTIVE
  To investigate the prevalence of hypertension and the relationship between hypertension and obesity in children and adolescents aged 6-18 years in Nanning, Guangxi Province, China.
  
  
  METHODS
  A stratified cluster random sampling method was adopted in Nanning to select 7 893 children and adolescents aged 6-18 years as research subjects. Questionnaire surveys were conducted, and blood pressure, height, weight, and other indicators of growth and development were measured.
  
  
  RESULTS
  An increasing trend with age for both systolic blood pressure (SBP) and diastolic blood pressure (DBP) was observed. Detection rates of hypertension, high SBP (HSBP) and high DBP (HDBP) were 6.58%, 4.02% and 3.81%, respectively. The detection rates of hypertension and HSBP in boys were significantly higher than in girls (P&lt;0.05). The detection rates of hypertension in normal, overweight and obesity groups were 3.87%, 9.84% and 19.23%, respectively. The obesity group showed the highest detection rates for hypertension, HSBP and HDBP, followed by the overweight group and normal group. Compared with that in the normal group, the odds ratios (95% CI) for hypertension in the overweight and obesity groups were 2.71 (1.69-5.96) and 5.91 (3.46-7.63), respectively. Blood pressure showed a positive correlation with age, height, weight and BMI (P&lt;0.01).
  
  
  CONCLUSIONS
  The present study provides with the current information and characteristics of blood pressure of children and adolescents aged 6-18 years in Nanning, Guangxi. Blood pressure is correlated with gender, age, height, weight and BMI. Obesity is positively correlated with the prevalence of hypertension and the risk of hypertension increases with body weight.
