AIM
To investigate the probability of marriage and divorce among Swedish military veterans deployed to Afghanistan relative to non-deployed matched comparators.
STUDY DESIGN AND SETTING
Matched cohort study in Sweden.
PARTICIPANTS
Military veterans were identified through Swedish military personnel registers regarding foreign deployments, and comparators from the Military Service Conscription Register (1969-2013). Of 1,882,411 eligible conscripts, 7041 had served in Afghanistan at some point in time between 2002 and 2013. To each military veteran, up to 5 non-deployed comparators who underwent conscription were matched by age, sex, psychological assessment, cognitive ability, psychiatric history and social characteristics. After matching there were 4896 (82%) unmarried and 1069 (18%) married deployed military veterans. The main outcome was marriage or divorce after deployment to Afghanistan. Data on marital status were retrieved from Statistics Sweden until December 31, 2014.
RESULTS
During a median follow-up of 4.1 years after deployment of married individuals, 124 divorces were observed among deployed military veterans and 399 in the matched non-deployed comparator cohort (277 vs. 178 per 10,000 person-years; adjusted hazard ratio 1.61, 95%CI 1.31-1.97). During a median follow-up of 4.7 years after deployment in the unmarried cohort, 827 new marriages were observed among deployed military veterans and 4363 in the matched non-deployed comparators cohort (399 vs. 444 per 10,000 person-years; adjusted hazard ratio 0.89, 95%CI 0.83-0.96).
CONCLUSION
Military veterans were more likely to divorce and less likely to marry after deployment compared with matched non-deployed comparators.
目的
调查在阿富汗部署的瑞典退伍军人与未部署的匹配对照者相比结婚和离婚的概率。
研究设计和设置
在瑞典进行的匹配队列研究。
参与者
通过瑞典军事人员部署记录确定退伍军人，并通过兵役应征登记册（1969-2013 年）确定对照者。在 1882411 名符合应征条件的应征者中，有 7041 人在 2002 年至 2013 年间曾在阿富汗服役过一段时间。对于每一位退伍军人，根据年龄、性别、心理评估、认知能力、精神病史和社会特征，与最多 5 名未部署的对照者进行匹配。匹配后，有 4896 名（82%）未婚和 1069 名（18%）已婚的退伍军人部署到阿富汗。主要结局是部署到阿富汗后的婚姻或离婚。婚姻状况数据从瑞典统计局检索到 2014 年 12 月 31 日。
结果
在已婚者部署后中位数为 4.1 年的随访期间，观察到部署退伍军人中有 124 例离婚，而在匹配的未部署对照组队列中有 399 例（每 10000 人年 277 例 vs. 178 例；调整后的危害比 1.61，95%CI 1.31-1.97）。在未婚队列部署后中位数为 4.7 年的随访期间，观察到部署退伍军人中有 827 例新婚姻，而在匹配的未部署对照组队列中有 4363 例（每 10000 人年 399 例 vs. 444 例；调整后的危害比 0.89，95%CI 0.83-0.96）。
结论
与匹配的未部署对照者相比，退伍军人在部署后更有可能离婚，结婚的可能性更小。
