BACKGROUND
Research connects health outcomes to hazard exposures but often neglects the nature of the exposure or repeated events.
METHODS
We undertook a cross-sectional study (N = 1,094) from a representative sample in the Houston Metropolitan Statistical Area (HMSA). Respondents were recruited using Qualtrics panels, targeting individuals reflecting the population of the HMSA. Physical composite scores (PCS) were calculated using the SF-12v2.
RESULTS
Among the hazards (hurricanes, flooding, tornadoes, chemical spills, industrial fires), only chemical spills showed a dose-response: physical health scores declined significantly with repeated exposures. This decline persisted after multiple linear regression. Covariates including sex, race, age, education, and chemical exposure affected PCS, but chemical spill exposure remained the most significant, negatively affecting PCS even after adjusting for other factors (coef =-2.24, 95% CI, -3.33 to -1.15).
CONCLUSION
Grasping the effects of hazards, especially repeated ones, can guide emergency management in mitigation, recovery, and preparedness efforts.
背景
研究将健康结果与危害暴露联系起来，但往往忽略了暴露的性质或重复事件。
方法
我们对休斯顿都会统计区（HMSA）的代表性样本进行了横断面研究（N=1094）。使用 Qualtrics 面板招募受访者，目标是反映 HMSA 人口的个体。使用 SF-12v2 计算身体综合评分（PCS）。
结果
在各种危害（飓风、洪水、龙卷风、化学品泄漏、工业火灾）中，只有化学品泄漏显示出剂量反应：身体健康评分随着反复暴露而显著下降。这一下降在多次线性回归后仍然存在。包括性别、种族、年龄、教育和化学品暴露在内的协变量影响了 PCS，但化学品泄漏暴露仍然是最重要的，即使在调整了其他因素后，它仍对 PCS 产生负面影响（系数=-2.24，95%CI，-3.33 至-1.15）。
结论
了解危害的影响，特别是重复危害的影响，可以指导应急管理部门在缓解、恢复和准备工作中采取措施。
