We find that Union Army veterans of the American Civil War who faced greater wartime stress (as measured by higher battlefield mortality rates) experienced higher mortality rates at older ages, but that men who were from more cohesive companies were statistically significantly less likely to be affected by wartime stress. Our results hold for overall mortality, mortality from ischemic heart disease and stroke, and new diagnoses of arteriosclerosis. Our findings represent one of the first long-run health follow-ups of the interaction between stress and social networks in a human population in which both stress and social networks are arguably exogenous.
我们发现，在美国内战中经历过更大战争压力（以更高的战场死亡率来衡量）的联邦军退伍军人在老年时的死亡率更高，但来自凝聚力更强的连队的男性受战争压力影响的可能性要小得多。我们的研究结果适用于总死亡率、缺血性心脏病和中风死亡率以及动脉硬化的新诊断。我们的研究结果是人类中压力和社交网络之间相互作用的首次长期健康随访之一，在这个人群中，压力和社交网络都可以说是外生的。
