Objective To analyze the association between overweight, obesity and high blood pressure among middle school students in Kaifeng city.
Methods A multi-stage stratified cluster sampling method was used to select 4 058 middle school students in Kaifeng City to measure blood pressure, height and weight, and to analyze the relationship between overweight and obesity and high blood pressure from September to October 2019.
Results The prevalence of high blood pressure in middle school students in Kaifeng was 11.78%. Compared with normal weight group, overweight ( OR=1.65) and obesity ( OR=3.32) were significantly correlated with the risk of high blood pressure ( P<0.01). The risk of high blood pressure in overweight and obese boys was 1.87-and 4.16-times higher than that in normal weight boys, respectively. The risk of high blood pressure for overweight and obese girls was 1.55-and 2.69-times higher than that for normal weight girls, respectively. The risk of high blood pressure in high school and normal weight group, middle school and overweight/obesity group, and high school and overweight/obesity group were 1.90, 2.85-and 3.39-times higher than that in middle school and normal weight group, respectively ( P=0.02).
Conclusion The prevention of high blood pressure in middle school students should start from the prevention of overweight and obesity, especially among overweight and obese boys. Risk of high blood pressure increases with grade among overweight/obese middle school students.
【摘要】 目的 探索开封市中学生超重、肥胖与血压偏髙之间的关联, 为相关部门制定有效的干预措施提供依据。 方法 2019年9一10月, 采用多阶段分层整群随机抽样方法, 选取开封市4 058名中学生进行血压、身髙、体重的测量, 分析超重 肥胖与血压偏髙的关系。 结果 中学生血压偏髙率为11.78%。与正常体重相比, 超重 ( OR=1.65)和肥胖 ( OR=3.32)均增 加血压偏髙的风险 ( P值均<0.01)。超重和肥胖男生血压偏髙的风险分别是正常体重者的1.87和4.16倍, 超重和肥胖女 生血压偏髙的风险分别是正常体重的1.55和2.69倍。髙中正常体重、初中超重/肥胖、髙中超重/肥胖学生的血压偏髙风 险分别是初中正常体重学生的1.90,2.85和3.39倍 ( P 交互=0.02)。 结论 预防中学生血压偏髙应该从预防超重/肥胖开 始, 尤其对男生加以重视;超重/肥胖的中学生学段越髙, 血压偏髙的风险越大。
