Alaska native suicide data were reviewed for every Alaska native suicide (N = 90) from death certificate data for the years 1979-1984 and compared to suicide statistics of age- and sex-matched groups of the entire U.S. population. The yearly suicide rate for Alaska natives was about twice that for the United States. Most of this difference was accounted for by dramatically and significantly greater rates for young, single, Alaska native men compared to white men in the U.S.; this was true for both the 15-24 and 25-34 age groups. With advancing age, suicide rates among Alaska natives decreased; the rates for the 35-44 and 45-54 male groups were still much greater, but not significantly so, than the rates for the comparable U.S. groups. After age 55, no suicides were reported for Alaska natives while U.S. white men had their highest suicide rates in the 55-64 and 65 and above groups. A number of social factors appear to have fueled the rise in suicide rates in young Alaska native men, including: economic growth, industrialization and changing lifestyles; prevalence of firearms; and a high rate of alcoholism.
对1979年至1984年死亡证明数据中每例阿拉斯加原住民自杀案例（N = 90）进行了回顾，并与美国全体人口年龄和性别匹配组的自杀统计数据进行了比较。阿拉斯加原住民的年自杀率约为美国的两倍。这种差异主要是由于阿拉斯加年轻单身男性的自杀率显著高于美国白人男性；15 - 24岁和25 - 34岁年龄组均是如此。随着年龄增长，阿拉斯加原住民的自杀率下降；35 - 44岁和45 - 54岁男性组的自杀率仍远高于美国相应组，但差异不显著。55岁以后，未报告阿拉斯加原住民自杀案例，而美国白人男性在55 - 64岁及65岁以上组的自杀率最高。一些社会因素似乎促使阿拉斯加年轻男性自杀率上升，包括：经济增长、工业化和生活方式改变；枪支的普及；以及高酗酒率。
