目的：了解上海市嘉定区社区居民急救知识现状，为针对性的提出普及急救知识内容及途径提供依据。方法采用系统随机抽样法对上海市嘉定区6个社区的384位居民进行问卷调查。结果收回有效问卷384份，有效率为94.12%。调查对象对急救知识总体知晓率为34.9%，其中，心肺复苏知晓率为53.4%，止血知识总知晓率达76.3%。在心肺复苏的各项知晓率中，心肺复苏总知晓率和呼吸知晓率随着年龄的增高而显著降低（均P<0.05)；高学历者多项知晓率显著高于低学历者（P<0.05）；有学习经历者总知晓率显著高于无学习经历者（81.34%vs 38.40%，P<0.01)。在止血总知晓率中，高学历者显著高于低学历者（P=0.011）。结论上海市嘉定区居民对急救知识的知晓率总体不高；学习经历对于提高急救知识水平非常重要，需加强心肺复苏知识的宣传，尤其在老年、低学历等人群中；应通过多元途径进行宣传，尤其需重视视频宣传及现场演练的宣传途径。“,”Objective To understand current level of first-aid knowledge and skills among the residents in Jiading District in Shanghai, and provide reference for popularizing basis for the spreading channel of the knowledge of first-aid.

For all cardiac resuscitation items, the awareness rates for cardiac resuscitation and breathing were lower in older people (P<0.05). The rates were higher in people with higher education than those with low education (P<0.05). The rates were higher in people who had learning experience than those in people without the experience (81.34%vs 38.40%, P<0.01). Among all hemostasis item, the rate was higher in people with high education than that in people with low education (P=0.011). Conclusion The total awareness rate of the knowledge of first-aid was low in Jiading communities. Having a learning experience is essential for improvement of first-aid knowledge.
