Although reassuring data on suicide risk in UK veterans of the 1982 Falklands conflict and 1991 Gulf conflict have been published, there have been few studies on long-term overall suicide risk in UK veterans.
To examine the risk of suicide in a broad population-based cohort of veterans in Scotland, irrespect ive of length of service or exposure to conflict, in comparison with people having no record of military service.
A retrospective 30-year cohort study of 56205 veterans born 1945-85 and 172741 matched non-veterans, using Cox proportional hazard models to compare the risk of suicide and fatal self-harm overall, by sex, birth cohort, length of service and year of recruitment.
There were 267 (0.48%) suicides in the veterans compared with 918 (0.53%) in non-veterans. The difference was not statistically significant overall [adjusted hazard ratio (HR) 0.99; 95% confidence interval (CI) 0.86-1.13]. The incidence was lower in younger veterans and higher in veterans aged over 40. Early service leavers were at non-significantly increased risk (adjusted HR 1.13; 95% CI 0.91-1.40) but only in the older age groups. Women veterans had a significantly higher risk of suicide than non-veteran women (adjusted HR 2.44; 95% CI 1.32-4.51, P < 0.01) and comparable risk to veteran men. Methods of suicide did not differ significantly between veterans and non-veterans, for either sex.
The Scottish Veterans Health Study adds to the emerging body of evidence that there is no overall difference in long-term risk of suicide between veterans and non-veterans in the UK. However, female veterans merit further study.
尽管已发表了关于1982年福克兰群岛冲突和1991年海湾冲突的英国退伍军人自杀风险的可靠数据，但针对英国退伍军人长期总体自杀风险的研究却很少。
在一个广泛的、基于人群的苏格兰退伍军人队列中，不论服役时长或是否经历冲突，与无服役记录的人群相比，研究自杀风险。
对1945年至1985年出生的56205名退伍军人和172741名匹配的非退伍军人进行了一项为期30年的回顾性队列研究，使用Cox比例风险模型按性别、出生队列、服役时长和入伍年份比较总体自杀和致命自残风险。
退伍军人中有267人（0.48%）自杀，非退伍军人中有918人（0.53%）自杀。总体差异无统计学意义[调整后风险比（HR）0.99；95%置信区间（CI）0.86 - 1.13]。年轻退伍军人的发病率较低，40岁以上退伍军人的发病率较高。早期退伍者的风险虽有非显著性增加（调整后HR 1.13；95% CI 0.91 - 1.40），但仅在年龄较大的组中如此。退伍女兵的自杀风险显著高于非退伍女性（调整后HR 2.44；95% CI 1.32 - 4.51，P < 0.01），与退伍男兵风险相当。退伍军人和非退伍军人之间，无论男女，自杀方式均无显著差异。
苏格兰退伍军人健康研究进一步证明，英国退伍军人和非退伍军人在长期自杀风险上总体无差异。然而，退伍女兵值得进一步研究。
