目标：患有慢性心脏病和肺病的人因暴露在极端环境高温下而面临患病和死亡的风险。在这里，我们描述了他们对风险的了解和意识，以及他们实践公共卫生和气象部门建议的防护行为的程度。 方法：在蒙特利尔炎热的夏季，从蒙特利尔大学五家医院诊所的参加者中依次现场或通过电话招募慢性心脏和/或肺功能不全患者。 238 名患者完成了为期一小时的面对面结构化访谈，其中 78% 的年龄至少为 60 岁。 结果：参与者充分了解酷热及其对健康的影响。大多数人认为自己容易受热影响，回忆起极端炎热的建议，并且所有人都采取了至少一项推荐的保护措施。在参与者中，68% 的人在酷暑期间呆在有空调的空间里，超过 75% 的人减少了体力活动并多喝水。一小部分人抵制使用空调：在没有空调的人中，32%的人“对购买空调信心不足”，即使他们的护理人员如此建议，25%的人会拒绝在长时间热浪期间在有空调的避难所过夜。结论：这些慢性病受访者认为自己容易受到酷热的影响，对预防有信心，几乎所有人都采取了建议的保护行为。少数人抵制保护性信息。
Objectives: Persons affected by chronic heart and lung disease risk illness and death through exposure to extreme ambient heat. Here we describe their knowledge and awareness of the risks, and the degree to which they practice the protective behaviours recommended by public health and meteorological authorities.Methods: Over the course of a hot Montreal summer, chronic cardiac and/or pulmonary insufficiency patients were recruited sequentially on site or by telephone from among attendees at five Montreal university hospital clinics. A one-hour face-to-face structured interview was completed by 238 patients, of whom 78% were at least 60 years of age.Results: Participants were well informed about extreme heat and its impact on health. Most see themselves as vulnerable to heat, recall extreme heat advisories, and all adopt at least one recommended protective measure. Of the participants, 68% spend time in an air-conditioned space during extreme heat episodes, and more than 75% reduce their physical activity and drink extra fluids. A small minority resists recourse to air conditioning: of those without, 32% have "little confidence in buying an air conditioner" even if so advised by their caregivers, and 25% would refuse to overnight in an air-conditioned shelter during a prolonged heat wave.Conclusions: These chronically ill respondents perceive themselves as susceptible to extreme heat, have confidence in prevention, and almost all adopt recommended protective behaviours. A minority resists protective messaging.
