Minority sexual orientation is a predictor of suicide ideation and attempts, though its association with suicide mortality is less clear. We capitalize on Sweden's extensively linked databases, to investigate whether, among married individuals, same-sex marriage is associated with suicide. Using a population-based register design, we analyzed suicide risk among same-sex married women and men (n = 6456), as compared to different-sex married women and men (n = 1181723) in Sweden. We selected all newly partnered or married individuals in the intervening time between 1/1/1996 and 12/31/2009 and followed them with regard to suicide until 12/31/2011. Multivariate Poisson regression was used to calculate adjusted incidence risk ratios (IRR) with 95 % confidence intervals (CI). The risk of suicide was higher among same-sex married individuals as compared to different-sex married individuals (IRR 2.7, 95 % CI 1.5-4.8), after adjustment for time at risk and socioeconomic confounding. Sex-stratified analyses showed a tentatively elevated risk for same-sex married women (IRR 2.5, 95 % CI 0.8-7.7) as compared to different-sex married women. Among same-sex married men the suicide risk was nearly three-fold greater as compared to different-sex married (IRR 2.895 % CI 1.5-5.5). This holds true also after adjustment for HIV status. Even in a country with a comparatively tolerant climate regarding homosexuality such as Sweden, same-sex married individuals evidence a higher risk for suicide than other married individuals.

瑞典已婚夫妇的自杀:同性伴侣的风险更大吗?

少数民族的性取向是自杀观念和尝试的预测因素,尽管其与自杀死亡率的关联尚不清楚。我们利用瑞典广泛链接的数据库来调查已婚个体之间的同性婚姻是否与自杀有关。使用基于人口的登记册设计,我们分析了在瑞典,同性已婚男女的自杀风险(n = 6456),而异性已婚男女是自杀风险(n = 1181723)。在1996年1月1日至2009年12月31日之间的这段时间内,我们选择了所有新近成为伴侣或已婚的人,并一直跟踪他们的自杀直至2011年12月31日。多元Poisson回归用于计算具有95%置信区间(CI)的调整后的发病风险比(IRR)。在调整风险时间和社会经济混杂因素之后,同性已婚个体的自杀风险高于异性已婚个体(IRR 2.7,95%CI 1.5-4.8)。性别分层分析显示,与同性已婚妇女相比,同性已婚妇女的风险暂时升高(IRR 2.5,95%CI 0.8-7.7)。在同性已婚男子中,自杀风险是同性已婚男子的近三倍(IRR 2.895%CI 1.5-5.5)。在调整了艾滋病毒感染状况之后,情况也是如此。即使在瑞典这样一个对同性恋气候比较宽容的国家,同性已婚个体的自杀风险也比其他已婚个体更高。经过风险时间调整和社会经济混乱之后。性别分层分析显示,与同性已婚妇女相比,同性已婚妇女的风险暂时升高(IRR 2.5,95%CI 0.8-7.7)。在同性已婚男子中,自杀风险是同性已婚男子的近三倍(IRR 2.895%CI 1.5-5.5)。在调整了艾滋病毒感染状况之后,情况也是如此。即使在瑞典这样一个对同性恋气候比较宽容的国家,同性已婚个体的自杀风险也比其他已婚个体更高。经过风险时间调整和社会经济混乱之后。性别分层分析显示,与同性已婚妇女相比,同性已婚妇女的风险暂时升高(IRR 2.5,95%CI 0.8-7.7)。在同性已婚男子中,自杀风险是同性已婚男子的近三倍(IRR 2.895%CI 1.5-5.5)。在调整了艾滋病毒感染状况之后,情况也是如此。即使在瑞典这样一个对同性恋气候比较宽容的国家,同性已婚个体的自杀风险也比其他已婚个体更高。在同性已婚男子中,自杀风险是同性已婚男子的近三倍(IRR 2.895%CI 1.5-5.5)。在调整了艾滋病毒感染状况之后,情况也是如此。即使在瑞典这样一个对同性恋气候比较宽容的国家,同性已婚个体的自杀风险也比其他已婚个体更高。在同性已婚男子中,自杀风险是同性已婚男子的近三倍(IRR 2.895%CI 1.5-5.5)。在调整了艾滋病毒感染状况之后,情况也是如此。即使在瑞典这样一个对同性恋气候比较宽容的国家,同性已婚个体的自杀风险也比其他已婚个体更高。
