Marital status is associated with survival.
The aims of this study are to evaluate marital history and timing on mortality during midlife, test the role of pre-marital personality, and quantify the role of health risk behaviors.
Cox proportional hazard models were run with varying classifications of marital history and sets of covariates.
In fully adjusted models compared to the currently married, lifetime marital history predicts premature mortality with never married at 2.33 times risk of death and ever married at 1.64 risk of death. Midlife marital history shows that not having a partner during midlife (hazard ratio (HR) = 3.10 formerly married; HR = 2.59 remaining single) has the highest risk of death. Controlling for personality and health risk behaviors reduces but does not eliminate the impact of marital status.
Consistency of marital status during midlife suggests that lack of a partner is associated with midlife mortality.
婚姻状况与生存有关。
本研究旨在评估中年时期的婚姻史和婚姻时机对死亡率的影响，检验婚前人格的作用，并量化健康风险行为的作用。
使用 Cox 比例风险模型进行分析，采用不同的婚姻史分类和一系列协变量。
在完全调整的模型中，与当前已婚者相比，一生的婚姻史预示着早逝风险，从未婚者的死亡风险是 2.33 倍，已婚者的死亡风险是 1.64 倍。中年时期的婚姻史表明，中年时期没有伴侣（离婚或鳏寡的风险比 (HR) = 3.10；一直单身的 HR = 2.59）的死亡风险最高。控制人格和健康风险行为后，虽然降低了婚姻状况的影响，但并未消除其影响。
中年时期婚姻状况的一致性表明，缺乏伴侣与中年死亡率有关。
