This study investigated suicides by people aged ten to 19 in Newfoundland and Labrador from 1977 to 1988. It is the first study of suicide in the province to use the records of death from all eight hospital pathology departments in the province and from the office of the Chief Forensic Pathologist. Cases were selected for the study using standardized criteria, independent of the manner of death recorded on the death certificate. A suicide rate of 4.37 per 100,000 was found. This rate and the age- and sex-specific suicide rates are lower than the official figures for Canada but higher than those reported in earlier Newfoundland studies. The rate for males was nearly five times the female rate, and the rate for people aged 15 to 19 was nearly six times that of people aged ten to 14. Suicide rates for Labrador were higher than for the island portion of the province for both Native and for non Native adolescents. Extremely high rates of suicide were found only among the Native population living in Northern Labrador, while none were recorded for Native people elsewhere. Firearms accounted for 54% and hanging for 33% of all suicides. Thirty percent of suicides occurred on a Saturday. Only 36 of the 63 deaths included in this study were designated as suicide on death certificates. The higher rate of under-reporting of suicide than in other jurisdictions suggests that official rates may not be useful for comparisons. The reasons for the high rate of under-reporting are discussed.
本研究调查了1977年至1988年期间纽芬兰和拉布拉多地区10至19岁人群的自杀情况。这是该省首次利用全省八个医院病理科以及首席法医病理学家办公室的死亡记录进行的自杀研究。研究采用标准化标准选取病例,独立于死亡证明上记录的死亡方式。研究发现自杀率为每10万人中有4.37人。该比率以及按年龄和性别划分的自杀率低于加拿大官方数据,但高于纽芬兰早期研究报告的数据。男性自杀率几乎是女性的五倍,15至19岁人群的自杀率几乎是10至14岁人群的六倍。拉布拉多地区原住民和非原住民青少年的自杀率均高于该省岛屿部分。仅在居住于拉布拉多北部的原住民中发现了极高的自杀率,而其他地区的原住民则未记录到自杀情况。所有自杀事件中,枪支占54%,上吊占33%。30%的自杀事件发生在周六。本研究纳入的63例死亡中,只有36例在死亡证明上被认定为自杀。与其他司法管辖区相比,自杀漏报率较高,这表明官方数据可能不适用于比较。文中讨论了漏报率高的原因。
