: The aim of this study was to examine the prevalence of heat-related illnesses (HRI) and their associated factors among rice farmers in Central Vietnam. : A cross-sectional study was conducted using a sample of 379 farmers from August to September 2021 in Ha Tinh province on the north-central coast of Vietnam. A structured questionnaire was used to collect demographic information, farming activities, heat exposure, and health issues. Multivariable logistic regression was used to identify the factors associated with HRI. : At least one HRI symptom was experienced by 83.4% of farmers, and two or more HRI symptoms were experienced by 55.1% of farmers during the last harvesting season (the summer-autumn rice season, 2021). Factors significantly associated with HRI were age, having chronic diseases, type of farming tasks, the number of hours working in the heat, and water intake. Farmers working outdoors for more than 4 hours in the heat were 2.3 times [95%CI: 1.14-4.69] more likely to experience HRI than those working fewer than 2 hours. A higher risk of HRI was also associated with heavy farming tasks (OR = 2.35, [1.34-4.14]), having hypertension (OR = 3.75, [1.90-7.81]), cardiovascular diseases (OR = 2.53, [1.03-6.93]), and other chronic conditions (OR = 2.51, [1.51-4.25]). In contrast, a lower risk of HRI was found in the older group (OR = 0.44, [0.22-0.87]) and increased water intake (OR = 0.46, [0.27-0.77]). : Hot weather is a significant occupational health risk for farmers in Vietnam. Changing the working schedule, working in shorter intervals, and remaining well-hydrated should be considered in HRI prevention strategies.
: 本研究旨在调查越南中北部沿海省份河静省农民中与热相关疾病（HRI）的患病率及其相关因素。: 2021 年 8 月至 9 月，我们在该省进行了一项横断面研究，样本量为 379 名农民。我们使用结构化问卷收集人口统计学信息、耕作活动、热暴露和健康问题。我们使用多变量逻辑回归来确定与 HRI 相关的因素。: 在过去的收获季节（2021 年夏秋稻季），83.4%的农民至少出现过一种 HRI 症状，55.1%的农民出现过两种或两种以上 HRI 症状。与 HRI 显著相关的因素包括年龄、患有慢性病、耕作任务类型、在热环境中工作的小时数和水的摄入量。在热环境中工作超过 4 小时的户外农民比工作少于 2 小时的农民更有可能出现 HRI，其患病风险为 2.3 倍[95%CI：1.14-4.69]。从事重体力耕作任务（OR=2.35，[1.34-4.14]）、患有高血压（OR=3.75，[1.90-7.81]）、心血管疾病（OR=2.53，[1.03-6.93]）和其他慢性疾病（OR=2.51，[1.51-4.25]）的农民发生 HRI 的风险也更高。相反，年龄较大的农民（OR=0.44，[0.22-0.87]）和增加水摄入量（OR=0.46，[0.27-0.77]）则可降低 HRI 的患病风险。: 炎热的天气对越南农民的职业健康构成了重大威胁。在预防 HRI 策略中，应考虑改变工作时间表、缩短工作间隔和保持充足水分摄入。
