To explore the relationship between blood pressure(BP) and physical development among children and adolescent in Nanjing, and to provide scientific basis for effective prevention and intervention of hypertension.Design and Method:
The survey was carried out on 10 091 students selected from 32 primary schools and 16 middle schools by random cluster sampling method. After providing informed consent, each student was asked to complete a standard questionnaire and to take physical examination. BP levels were measured by the data from large scale cross-sectional surveys in main land China since 2005. BMI was assessed by Z-score.Results:
The total prevalence of hypertension was 4.48%, and total prevalence of obesity was 12.6%. The prevalence of hypertension was increasing from normal weight, overweight to obesity (p < 0.0001). Multivariate logistic analysis indicated that obesity significantly increased to hypertension among children and adolescent and higher levels of physical activity were associated with lower BP.Conclusions:
There was significant correlation between hypertension and physical development among children and adolescent in Nanjing. More efforts should be made to prevent hypertension.
