Cross-sectional studies have shown contradictory results concerning the impact of combat exposure on mental health in later life. We examined whether combat exposure influences trajectories of mental health symptoms in older male veterans using longitudinal data collected from 1985 to 1991 in the Veterans Affairs Normative Aging Study ( = 1,105, age range = 40-86 years in 1985). Noncombat veterans showed little systematic change in depressive and anxiety symptoms with age, whereas combat veterans showed U-shaped nonlinear changes, with higher levels in midlife decreasing until the mid-60s and then increasing again in the 70s and 80s. These findings support the notion that military service, and especially combat exposure, is a hidden variable in aging research. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
横断面研究表明，战斗暴露对老年人心理健康的影响结果存在矛盾。我们使用退伍军人事务正常老化研究（1985 年至 1991 年共收集了 1105 名参与者，年龄范围为 40-86 岁）中的纵向数据，研究了战斗暴露是否会影响老年男性退伍军人的心理健康症状轨迹。非战斗退伍军人的抑郁和焦虑症状随年龄增长几乎没有系统变化，而战斗退伍军人则表现出 U 型非线性变化，中年时水平较高，一直下降到 60 多岁，然后在 70 多岁和 80 多岁再次上升。这些发现支持了这样一种观点，即兵役，特别是战斗暴露，是衰老研究中的一个隐藏变量。（APA，所有权利保留）。
