Prior research shows that work in agriculture and construction/extraction occupations increases the risk of environmental heat-associated death.
To assess the risk of environmental heat-associated death by occupation.
This was a case-control study. Cases were heat-caused and heat-related deaths occurring from May-October during the period 2002-2009 in Maricopa County, Arizona. Controls were selected at random from non-heat-associated deaths during the same period in Maricopa County. Information on occupation, age, sex, and race-ethnicity was obtained from death certificates. Logistic regression analysis was used to estimate odds ratios for heat-associated death.
There were 444 cases of heat-associated deaths in adults (18+ years) and 925 adult controls. Of heat-associated deaths, 332 (75%) occurred in men; a construction/extraction or agriculture occupation was described on the death certificate in 115 (35%) of these men. In men, the age-adjusted odds ratios for heat-associated death were 2.32 (95% confidence interval 1.55, 3.48) in association with construction/extraction and 3.50 (95% confidence interval 1.94, 6.32) in association with agriculture occupations. The odds ratio for heat-associated death was 10.17 (95% confidence interval 5.38, 19.23) in men with unknown occupation. In women, the age-adjusted odds ratio for heat-associated death was 6.32 (95% confidence interval 1.48, 27.08) in association with unknown occupation. Men age 65 years and older in agriculture occupations were at especially high risk of heat-associated death.
The occurrence of environmental heat-associated death in men in agriculture and construction/extraction occupations in a setting with predictable periods of high summer temperatures presents opportunities for prevention.
先前的研究表明，农业和建筑/采掘业的工作增加了与环境热相关的死亡风险。
评估职业与环境热相关死亡的风险。
这是一项病例对照研究。病例为 2002 年至 2009 年 5 月至 10 月期间在亚利桑那州马里科帕县发生的与热相关的死亡；对照则是在同一时期马里科帕县非与热相关的死亡中随机选择的。从死亡证明中获取职业、年龄、性别和种族信息。采用逻辑回归分析估计与热相关的死亡的优势比。
在成年人（18 岁以上）中，有 444 例与热相关的死亡病例和 925 例成人对照。在与热相关的死亡病例中，有 332 例（75%）发生在男性中；在这些男性中，有 115 例（35%）的死亡证明上描述了建筑/采掘或农业职业。在男性中，与建筑/采掘相关的与热相关的死亡的年龄调整后优势比为 2.32（95%置信区间 1.55，3.48），与农业相关的为 3.50（95%置信区间 1.94，6.32）。职业不明的男性与热相关的死亡的优势比为 10.17（95%置信区间 5.38，19.23）。在女性中，与职业不明相关的与热相关的死亡的年龄调整后优势比为 6.32（95%置信区间 1.48，27.08）。在农业职业中年龄 65 岁及以上的男性尤其面临与热相关的死亡的高风险。
在高温夏季可预测时期，农业和建筑/采掘业职业的男性发生与环境热相关的死亡的情况提示存在预防机会。
