目的了解南京市城区成年居民的业余时间体力活动的流行病学分布特征。方法 2007年7—9月对南京市主城区中2个区内的6个居民小区30岁以上居民应用国际体力活动量表进行体力活动相关的现况调查,采用logistic回归分析社会经济因素与充足体力活动之间的关联。结果实际调查3 376人,应答率为91.6%。城区成年居民中业余时间从事中等强度体力活动为10.3%,达到充足体力活动标准者为8.2%。从事中等强度业余时间体力活动者的平均每天的活动时间为(47.6±33.7)min。性别与年龄对从事中等强度体力活动者有显著影响,女性、年长者参与中等强度业余体力活动的可能性显著小于男性和年轻者。结论南京城区成年居民的中等强度业余体力活动的水平有待进一步提高,可以根据不同性别和年龄的人群设计不同的体力活动促进项目。

Logistic regression was used to analyze the socio-economic factors Correlation between physical activity. Results The actual survey of 3 376 people, the response rate was 91.6%. Urban residents in the spare time engaged in moderate-intensity physical activity was 10.3%, to achieve adequate standards of physical activity was 8.2%. The average daily activity time of those engaged in moderate-intensity spare time physical activity was (47.6 ± 33.7) min. Gender and age have a significant impact on those who engage in moderate-intensity physical activity. Women and seniors are significantly less likely to participate in medium-intensity amateur physical activities than men and young people. Conclusions The level of medium strength amateur physical activity of adult residents in Nanjing urban area needs to be further improved. Different physical activity promotion projects can be designed according to different gender and age groups.
