The aim of this study was to determine the association between blood pressure and the frequency of structured physical training activity in Chinese adolescents. A total of 9558 students aged 11-18 years underwent anthropometric and blood pressure measurements in a cross-sectional growth study. Structured physical training activity was assessed by two simple self-administered questions and parents were asked to complete a questionnaire providing demographic information. Ninety per cent of eligible students participated in the study, of which 94% provided data on physical training frequency for final analysis. Of the boys, 22.6% and of the girls, 14.5% were physically active with extracurricular school exercise at least twice a week. Over half of the students did not regularly exercise except during physical education classes at school. Blood pressure had a positive correlation with body mass index (BMI). Both systolic blood pressure and diastolic blood pressure were substantially decreased with increased training frequency (P<0.05). Logistic regression adjusting for age, family history of hypertension, BMI and sleep duration showed that exercising two or more times a week had a negative relation with hypertension (odds ratio: 0.63, 95%CI 0.47-0.85). In conclusion, structured physical training activity of two or more times a week has a beneficial effect on blood pressure in Hong Kong children aged 11-18 years.
本研究旨在探讨血压与中国青少年有规律的体育锻炼频率之间的关系。在一项横断面生长研究中，共有 9558 名 11-18 岁的学生接受了人体测量和血压测量。有规律的体育锻炼活动通过两个简单的自我管理问题进行评估，并要求家长填写一份提供人口统计学信息的问卷。90%符合条件的学生参加了研究，其中 94%提供了关于体育锻炼频率的最终分析数据。男孩中有 22.6%，女孩中有 14.5%的人每周至少两次参加课外学校运动，属于活跃的运动者。超过一半的学生除了在学校上体育课之外，没有定期进行锻炼。血压与体重指数（BMI）呈正相关。收缩压和舒张压均随训练频率的增加而显著降低（P<0.05）。经过年龄、高血压家族史、BMI 和睡眠时间调整的逻辑回归显示，每周锻炼两次或以上与高血压呈负相关（比值比：0.63，95%可信区间 0.47-0.85）。综上所述，每周进行两次或以上的有规律的体育锻炼对香港 11-18 岁儿童的血压有有益的影响。
