摘　　要：目的评价社区综合干预对杭州市3个社区成人体力活动水平的短期影响。方法采用平行对照、非随机分组的类实验设计，以杭州市下城区和拱墅区作为干预区，开展为期2年的社区综合干预，同期以西湖区作为对照区，并在干预前后通过两次独立横断面问卷调查评价社区综合干预对居民体力活动水平的短期影响。结果基线和随访各完成调查2016人（干预区1016人和对照区1000人）。干预区居民在干预前后对体力活动益处的认知水平有下降趋势；对照区未见有统计学意义的变化。干预区居民总体力活动水平（代谢当量，MET-min／w）由1204显著性增长到1386（P=0．023），对照区由918增长至924，变化的差异无统计学意义（P=0．201），控制调查对象年龄构成变化的可能影响后，结果不变。结论经2年干预，干预区人群总体力活动水平得到有益的改变。在杭州市城区针对居民体力活动水平开展以社区为基础的综合干预项目具有可行性和有效性。Objective To evaluate the short-term impact of comprehensive community- based intervention on physical activity （PA） of adults living in the three urban communities of Hangzhou city. Methods Within the framework of Community Interventions for Health （CIH） Program, a community trial was conducted in two urban areas （Xiacheng district and Gongshu district） and an urban area （Xihu district） as control, by a parallel comparison and random grouping based quasi-experimental design. Two independent questionnaire-based surveys of cross-sectional samples in the intervention and comparison areas were used to assess the short-term impact of the intervention program. Results A total of 2016 adults at baseline and 2016 adults at follow-up stages, completed the survey, including 1016 adults from the intervention areas and 1000 from the comparison area. Over the two-year intervention period, the cognitive level on benefits of physical activity in the intervention areas were trending downward. The changes observed in the comparison area did not show statistical significance. Intervention areas showed a statistically significant increase （1204 vs. 1386, P=0.023） in the level of physical activity （metabolic equivalent, MET-minutes/ week） compared with the comparison area （918 vs. 924, P=0.201）. And results remained the same after eliminating the possible effects of age factor. Conclusion After a two-year intervention, beneficial changes were noted in the intervention areas with respect to the level of physical activity. A community-based intervention program on physical activity seemed feasible and effective in the urban areas of Hangzhou.
