Minority sexual orientation has been repeatedly linked to elevated rates of suicide attempts. Whether this translates into greater risk for suicide mortality is unclear. We investigated sexual orientation-related differences in suicide mortality in Denmark during the initial 12-year period following legalization of same-sex registered domestic partnerships (RDPs).
Using data from death certificates issued between 1990 and 2001 and population estimates from the Danish census, we estimated suicide mortality risk among individuals classified into one of three marital/cohabitation statuses: current/formerly in same-sex RDPs; current/formerly heterosexually married; or never married/registered.
Risk for suicide mortality was associated with this proxy indicator of sexual orientation, but only significantly among men. The estimated age-adjusted suicide mortality risk for RDP men was nearly eight times greater than for men with positive histories of heterosexual marriage and nearly twice as high for men who had never married.
Suicide risk appears greatly elevated for men in same-sex partnerships in Denmark. To what extent this is true for similar gay and bisexual men who are not in such relationships is unknown, but these findings call for targeted suicide prevention programs aimed at reducing suicide risk among gay and bisexual men.
少数性取向与自杀企图率升高有关。但这是否转化为自杀死亡率的更高风险尚不清楚。我们研究了丹麦同性注册伴侣关系合法化后的最初 12 年期间，性取向相关的自杀死亡率差异。
利用 1990 年至 2001 年期间签发的死亡证明和丹麦人口普查的人口估计数，我们对三类婚姻/同居状况的个人进行了自杀死亡率风险估计：当前/以前处于同性注册伴侣关系中；当前/以前异性已婚；或从未结婚/注册。
自杀死亡率与这一性取向的替代指标有关，但仅在男性中具有显著相关性。调整年龄后，RDP 男性的自杀死亡率估计值是异性婚姻史阳性男性的近 8 倍，是从未结婚男性的近 2 倍。
在丹麦，男同性恋伴侣的自杀风险似乎大大升高。在没有这种关系的类似男同性恋和双性恋男性中，这种情况在多大程度上是真实的尚不清楚，但这些发现呼吁制定有针对性的自杀预防计划，以降低男同性恋和双性恋男性的自杀风险。
