中国九省区成人生活行为对血压的影响

目的:比较四种生活行为(膳食、体力活动、吸烟、饮酒)单独或不同组合对血压的影响。方法:以2006年中国健康与营养调查18岁及以上成人为研究对象,采用"DASH分数"表示膳食摄入、"代谢当量.分钟"表示体力活动水平,将调查对象分别按膳食、体力活动、吸烟和饮酒等4种生活行为分层。结果:血压随DASH总分、体力活动总量增加而降低,随吸烟或饮酒量增加而升高。与没有不良生活行为的调查对象相比,有4种不良生活行为将导致平均收缩压升高近5(男)和10(女)mmHg,血压达到诊断水平的相对风险升至2.38(男)和2.02(女)倍。结论:膳食不均衡、体力活动量减少、吸烟、过量饮酒这些行为的累加,将伴随高血压患病风险的升高,而血压升高往往提示这些不良生活行为的存在。

Effect of Lifestyle Behaviors on Blood Pressure in Chinese Adults from 9 Provinces

Objective] To investigate the independent and joint effect of 4 kinds of lifestyle behaviors including diet, physical activity （PA）, smoking, alcohol consumption on blood pressure. Methed] Diet and PA were stratified assessed using DASH score and Metabolic E- quivalent · min respectioely in participants （ 18 years and older） of China Health and Nutrition Surveys in 2006. Participants were Stvatifie- daccording to diet, PA, smoking and alcohol consumption, respectively. Result ] Blood pressure decreased with increase of DASH score and PA quartiles, but increased with smoking and excessive alcohol consumption. Compared with participants who had no high-risk behav- iors, those who had all 4 high-risk behaviors experienced additional 5 （male） or 10 （female） mmHg of systolic blood pressure, and in- creased risk of high blood pressure （ OR = 2. 38 for male and 2. 02 for female） . Condusion] Unhealthy diets, sedentary behavior, smoking and excessive alcohol consumption were associated with increasing risk of high blood pressure.
