Recent studies have reported an association between natural disasters of various kinds and ischemic heart disease (IHD). We investigated the association between Disability-adjusted life years (DALYs) due to IHD and natural disasters and aimed to assess DALYs as a quantification of the burden of IHD related to natural disasters at the global level.
Country-specific data of natural disaster impacts DALYs due to IHD and socioeconomic variables were obtained from open sources over the period of 1990-2013 and 2014-2017. A population-based trend ecological design was conducted to estimate the association between trends in DALYs and natural disasters (occurrence, casualties and total damage), adjusting for socioeconomic variables.
Most countries have experienced increases in natural disaster occurrences and decreases in DALYs during this study period. The unadjusted correlation analysis demonstrated a positive and significant correlation between DALYs and natural disasters for females and for both sexes (R = 0.163 and 0.146, p = 0.024 and 0.043), and a marginally significant correlation for males (R = 0.128, p = 0.076). After adjusting for socioeconomic variables, multiple linear regression demonstrated independent associations between the occurrence and DALYs due to IHD for males, females and both sexes (standardized coefficients = 0.192, 0.23 and 0.187, p = 0.016, 0.004 and 0.022).
A weak but significantly positive association between natural disaster and IHD was confirmed and quantified at the global level by this DALY metric analysis. Adaptation strategies for natural disaster responses and IHD disease burden reduction need to be developed.
最近的研究报告了各种类型的自然灾害与缺血性心脏病（IHD）之间存在关联。我们调查了因 IHD 导致的残疾调整生命年（DALY）与自然灾害之间的关联，并旨在评估 DALY 作为量化与自然灾害相关的 IHD 负担的指标，以评估全球范围内的情况。
从 1990-2013 年和 2014-2017 年的公开来源获取了特定国家因 IHD 导致的自然灾害影响 DALY 及社会经济变量的数据。采用基于人群的趋势生态学设计，在调整社会经济变量的情况下，估计 DALY 与自然灾害（发生、伤亡和总损失）趋势之间的关联。
在本研究期间，大多数国家经历了自然灾害发生次数的增加和 DALY 的减少。未调整的相关分析表明，DALY 与女性和两性的自然灾害之间存在正相关且具有统计学意义（R = 0.163 和 0.146，p = 0.024 和 0.043），而男性的相关性则具有统计学意义（R = 0.128，p = 0.076）。在调整社会经济变量后，多元线性回归表明，男性、女性和两性的自然灾害发生与 IHD 所致 DALY 之间存在独立关联（标准化系数= 0.192、0.23 和 0.187，p = 0.016、0.004 和 0.022）。
通过 DALY 指标分析，在全球范围内确认并量化了自然灾害与 IHD 之间的微弱但具有统计学意义的正相关关系。需要制定针对自然灾害应对和 IHD 疾病负担减轻的适应策略。
