During the 35-year period 1951 through 1985, 274 completed suicides occurred among residents of Olmsted County, Minnesota. The overall age- and sex-adjusted incidence was 12.5 per 100,000 person-years (95% confidence interval, 11.0 to 14.0), similar to the national averages, and rates were comparable for urban and rural portions of the county. Men outnumbered women 3.6 to 1, and the sex ratio of age-adjusted incidence rates was 4.5:1. The incidence rates increased after middle age for men but not for women. The most common suicide methods were gunshot wounds for men and poisoning for women. Two-thirds of the suicides occurred at home and were usually discovered by family members or friends. Almost half of all suicide victims were unmarried. This figure seems high, as does the greater proportion of unemployed persons than employed persons among those who committed suicide, but denominator data are unavailable.
在1951年至1985年的35年期间,明尼苏达州奥尔姆斯特德县的居民中发生了274起自杀身亡事件。经年龄和性别调整后的总体发病率为每10万人年12.5例(95%置信区间为11.0至14.0),与全国平均水平相似,且该县城乡地区的发病率相当。男性自杀人数是女性的3.6倍,年龄调整发病率的性别比为4.5:1。男性中年后的发病率上升,而女性则不然。最常见的自杀方式,男性是枪击,女性是中毒。三分之二的自杀事件发生在家中,通常由家人或朋友发现。几乎一半的自杀受害者未婚。这个数字似乎偏高,自杀者中失业者的比例高于就业者这一情况也是如此,但分母数据无法获取。
