A cohort analysis was undertaken of the 4,315 deaths by suicide registered in Alberta, Canada, Vital Statistics between the years of 1951 and 1977, inclusive. Age, gender, and year of death were available in all but two instances. Five-year age cohorts were identified and their suicide rates were followed as the cohorts aged. Analyses were done for men and women separately and combined. Suicide rates increased directly with age, regardless of gender for each cohort observed. Once a cohort entered the 15- to 19-year-old age range with a high rate of suicide, the rate for that cohort remained consistently high as it aged.
对1951年至1977年（含）期间加拿大艾伯塔省生命统计登记的4315例自杀死亡病例进行了队列分析。除两例情况外，所有病例均有年龄、性别和死亡年份信息。确定了五岁年龄组，并随着这些年龄组的变老跟踪其自杀率。分别对男性和女性进行了分析，并进行了综合分析。观察到的每个年龄组的自杀率均随年龄直接上升，与性别无关。一旦某个年龄组进入自杀率较高的15至19岁年龄范围，该年龄组的自杀率在其变老过程中就一直居高不下。
