The underlying mechanism for deterioration in cardiometabolic health after major natural disasters is unknown. We leveraged natural experiment data stemming from the 2011 Great East Japan Earthquake and Tsunami (n = 1165) to examine whether specific types of post-disaster accommodations explain the association between disaster-related property damage and objectively measured cardiometabolic profiles of older disaster survivors. Causal mediation analysis showed that relocation to trailer-style temporary shelters largely mediated the associations between home loss and unhealthy changes in anthropometric measures (72.6% of 0.65 kg/m for body mass index and 62.3% of 3.89 cm for waist circumference), but it did not mediate the associations with serum lipid measures. This study demonstrates that there are outcome-specific pathways linking disaster damage and health of survivors.
重大自然灾害后，心代谢健康状况恶化的潜在机制尚不清楚。我们利用源于 2011 年东日本大地震和海啸的自然实验数据（n=1165），检验灾后特定类型的住所安置是否可以解释与灾难相关的财产损失与老年受灾幸存者客观测量的心代谢特征之间的关联。因果中介分析表明，搬迁到拖车型临时住所在很大程度上解释了住房损失与人体测量指标不健康变化之间的关联（体重指数增加 0.65kg/m2 的比例为 72.6%，腰围增加 3.89cm 的比例为 62.3%），但与血脂指标的关联则无法解释。本研究表明，存在特定结果的途径将灾难破坏与幸存者的健康联系起来。
