[目的]了解南京市某区居民对热浪健康风险的认知现状及相关影响因素。[方法]随机选择南京市某2个社区,用面对面询问方式调查居民654人。采用卡方检验、多变量logistic回归等方法对热浪风险认知相关因素进行分析。[结果]有效问卷642份,有效回收率98.9%。居民对高温的认知为(34.6±2.66)℃,热浪对生活的影响程度在一般至比较严重之间,居民热浪相关知识水平较低,应对意愿较高;感知觉、风险评估、知识水平各维度之间均呈正相关。logistic回归分析结果提示,老年人无中暑经历者(OR=1.2×10-7)对热浪风险评估低,慢病人群中步行者(OR=2.763)、无中暑经历者(OR=7.9×10-7)对热浪风险评估低。[结论]南京某社区居民对热浪的风险认知和知识水平较低,个人健康状况和生活习惯是影响热浪风险认知的重要因素。
[Objective] To understand the status quo and the related factors of residents’ health awareness in heat-wave in a certain area of Nanjing. [Methods] A random sample of 2 communities in Nanjing was surveyed by face-to-face interviews with 654 residents. Using chi-square test and multivariate logistic regression analysis, the related factors of heat wave risk cognition were analyzed. [Result] There are 642 effective questionnaires, the effective recovery rate is 98.9%. The residents ’cognition to high temperature is (34.6 ± 2.66) ℃, and the impact of heatwave on living is between normal and severe. Residents’ heatwave-related knowledge is low and their willingness to respond is high. Sense perception, risk assessment and knowledge level There is a positive correlation between dimensions. The results of logistic regression analysis indicated that the elderly with no experience of sunstroke (OR = 1.2 × 10-7) had a low assessment of heatwave risk, and those with chronic stress (OR = 2.763), those without sunstroke (OR = 7.9 × 10- 7) Low heat risk assessment. [Conclusion] Residents of a certain community in Nanjing have a low cognition and knowledge about the risk of heatwaves. Personal health status and lifestyle are important factors that influence the risk perception of heatwaves.
