目的探索影响居民热浪风险感知的主要因素。方法采用横断面研究于2013年7—8月调查了北京市顺义区15-79岁的591名居民对热浪的感知,运用因子分析将问卷中10个问题合并为严重度、关注度和信任度3个因子,然后采用多水平统计模型对3个因子进行分析。结果对于热浪严重度感知,有热浪经历者高于无热浪经历者,吸二手烟居民高于吸烟居民。对于热浪关注度感知,女性比男性高;随居民年龄增长,感知水平随之升高;教育水平提高,感知水平随之提高;目前,通过电视、网络、手机等途径获取热浪信息尚不丰富。对于热浪防护相关措施信任度感知,随年龄增长,信任度随之升高;商业、服务人员高于机关等单位负责人;收入较高居民信任度较低;拥有目前医疗保障形式的居民对热浪防护的信任度较低。结论不同人口特征、热浪经历、获取热浪信息的方式及医疗保障降低热浪健康风险的信任度是影响居民对热浪风险感知的关键因素,建议加强热浪健康风险宣传,针对不同人群采取不同的热浪防护指导。

英文摘要：

Objective To identify the main influencing factors of risk perception of heat waves in Shunyi district of Beijing.Methods A cross-sectional study was conducted during the summer of 2013 among residents aged 15- 79 in Shunyi district,Beijing. Factor analysis was used to merge ten questions of the participants ＇ perceptions into three factors that were perceived susceptibility, perceived severity and perceived trust. Multilevel model analysis was performed to determine the factors of risk perception during a heat wave. Results For the perceived severity of heat waves, the perception of the participants who had heat wave experience was higher than that of those who had no heat wave experience. Also, the perception of participants exposed to secondhand-smoke was higher than that of the smokers. For the perceived susceptibility of heat wave, the perception of female was higher than that of male. Those who were older and gained higher education were more likely to have higher perception. The extent of recieving heat wave information from TV,internet and mobile phone and so on was lower. For the trust perception of heat wave, the people showed an increasing degree of trust with their age increasing. The service staff had higher trust perception compared with the unit leaders. The people with higher income had lower trust on the measures to minimize the health risk of heat wave. Also, the people who selected health insurance had lower trust on the measures to minimize the health risk of heat wave than those who did not have health insurance. Conclusion The variables of demographic characteristics, experience of heat waves, the extent of having heat wave information, trust on the government ＇s behavior of medical insurance have significant effects on heat waves risk perception. Therefore, the key implication for heat waves intervention is to strengthen the health promotion and guidance should be designed and promoted to dealing with people with different demographic characteristics.
