目的探讨中老年人不同运动强度的体育活动水平与血压的关系。方法1999年1～2月对广州市珠光街的部分中老年人(51～75岁)进行了两个阶段抽样调查。调查内容包括一般情况、业余体育活动水平、血压(BP)等。完成调查的254人中98人已知患有慢性心血管疾病,本研究仅对其余156人(男63人,女93人)进行分析。结果156人中总运动量从0～48.6Mets-h/周,支出在不同运动强度(低、中低、中高)水平的运动量明显呈左偏态分布。用倒退法多元回归分析显示:BP与中高强度以上活动水平独立相关。结论总体上较高强度活动水平有较低BP。 Objective To explore the relationship between the level of physical activity and blood pressure of different exercise intensity in the elderly. Methods From January to February 1999, we conducted a two-stage sampling survey of some middle-aged and elderly people (51-75 years old) in Zhuguang Street, Guangzhou City. The survey includes the general situation, amateur sports activities, blood pressure (BP) and so on. Of the 254 respondents who completed the survey, 98 were known to have chronic cardiovascular disease and the remaining 156 (63 males and 93 females) were analyzed in this study. Results The total amount of exercise in 156 people from 0 ~ 48.6Mets-h / week, expenditures at different levels of exercise intensity (low, medium, high) levels were significantly left-skewed distribution. Multivariate regression analysis using regression analysis showed that BP was independently associated with activity levels above mid-high intensity. Conclusion Overall, higher intensity activity levels have lower BP.
