Studies show marriage to be protective against suicide though with variation in the extent to which suicide rates are higher among the never married, separated or divorced and widowed. We examined suicide in Northern Ireland by marital status and examined whether the observed variation differed by sex and age.
Data relating to all 1,398 suicide deaths (ICD-9 E950-959 and ICD-10 X60-84) registered in 1996-2005 were analysed using Poisson regression.
The total, male and female age-standardised suicide rates were 8.4, 13.6 and 3.3 per 100,000, respectively. Never marrying increased male suicide risk and its effect increased with age (incidence rate ratio (IRR) among 20-34 year-olds = 1.47, 95% confidence interval (CI) = 1.19-1.84; IRR among over 55 year-olds = 2.33, 95% CI = 1.55-3.50). Never marrying was a risk factor for women only if aged 20-34 years (IRR = 3.05, 95% CI = 1.70-5.47). Among over 55 year-olds, widowhood increased risk of male suicide only (IRR = 2.47, 95% CI = 1.64-3.70) whereas divorce was associated with an almost threefold increase in male (IRR = 2.61, 95% CI = 1.39-4.88) and female (IRR = 2.57, 95% CI = 0.89-7.42) suicide relative to married persons. The effect of divorce was far more pronounced in 20-34 year-old men (IRR = 5.59, 95% CI = 3.58-8.67) and women (IRR = 9.46, 95% CI = 3.81-23.37).
In Northern Ireland, marriage protects both sexes against suicide though men more so than women. Divorced young men, in particular, are a population at high risk of suicide.
研究表明，婚姻对自杀具有保护作用，但在从未结婚、分居或离婚以及丧偶的人群中，自杀率更高的程度存在差异。我们通过婚姻状况检查了北爱尔兰的自杀情况，并研究了观察到的差异是否因性别和年龄而异。
使用泊松回归分析了 1996-2005 年期间登记的所有 1398 例自杀死亡（ICD-9 E950-959 和 ICD-10 X60-84）相关数据。
总人群、男性和女性年龄标准化自杀率分别为每 100,000 人 8.4、13.6 和 3.3 例。从未结婚会增加男性自杀风险，且这种影响随着年龄的增长而增加（20-34 岁人群的发病率比（IRR）= 1.47，95%置信区间（CI）= 1.19-1.84；55 岁以上人群的 IRR = 2.33，95% CI = 1.55-3.50）。只有在 20-34 岁的女性中，从未结婚才是自杀的危险因素（IRR = 3.05，95% CI = 1.70-5.47）。55 岁以上人群中，丧偶仅增加男性自杀风险（IRR = 2.47，95% CI = 1.64-3.70），而离婚则使男性（IRR = 2.61，95% CI = 1.39-4.88）和女性（IRR = 2.57，95% CI = 0.89-7.42）自杀的风险增加近三倍，与已婚人士相比。离婚对 20-34 岁男性（IRR = 5.59，95% CI = 3.58-8.67）和女性（IRR = 9.46，95% CI = 3.81-23.37）的影响更为显著。
在北爱尔兰，婚姻对男女双方都有保护作用，但男性比女性更明显。特别是年轻离婚男性是自杀风险较高的人群。
