The death certificates and coroners' reports for all suicides, undetermined causes of death, and questionable accidents were obtained from the Pennsylvania Department of Vital Statistics for 10- to 19-year-old residents of Allegheny County, Pennsylvania, from 1960 to 1983. During the 24-year study period, 159 cases of definite suicide and 38 cases of likely suicide were noted. The suicide rate increased markedly among youth during the study period, particularly among white males aged 15 to 19 years, and was not due to changes in classification procedures over time. The suicide rate by firearms increased much faster than the suicide rate by other methods (2.5 vs 1.7-fold). The proportion of suicide victims who had detectable blood alcohol levels rose 3.6-fold from 12.9% in 1968 to 1972 to 46.0% in 1978 to 1983. Suicide victims who used firearms were 4.9 times more likely to have been drinking than were those who used other methods of suicide. The availability of firearms and the increased use of alcohol among youth may have made a significant contribution to the increase in the suicide rate among the young.
从宾夕法尼亚州生命统计局获取了1960年至1983年宾夕法尼亚州阿勒格尼县10至19岁居民所有自杀、死因不明以及可疑事故的死亡证明和验尸官报告。在24年的研究期间，记录了159例明确自杀案例和38例可能自杀案例。在研究期间，青少年自杀率显著上升，尤其是15至19岁的白人男性，且并非由于分类程序随时间变化所致。使用枪支的自杀率增长速度远快于其他自杀方式的自杀率（分别增长了2.5倍和1.7倍）。自杀受害者血液中可检测到酒精含量的比例从1968年至1972年的12.9%上升了3.6倍，至1978年至1983年达到46.0%。使用枪支自杀的受害者饮酒的可能性是使用其他自杀方式者的4.9倍。青少年枪支的可得性以及饮酒行为的增加可能对年轻人自杀率的上升起到了重要作用。
