To determine rates of suicide associated with pregnancy by the type of pregnancy.
Register linkage study. Information on suicides in women of reproductive age was linked with the Finnish birth, abortion, and hospital discharge registers to find out how many women who committed suicide had had a completed pregnancy during her last year of life.
Nationwide data from Finland.
Women who committed suicide in 1987-94.
There were 73 suicides associated with pregnancy, representing 5.4% of all suicides in women in this age group. The mean annual suicide rate was 11.3 per 100,000. The suicide rate associated with birth was significantly lower (5.9) and the rates associated with miscarriage (18.1) and induced abortion (34.7) were significantly higher than in the population. The risk associated with birth was higher among teenagers and that associated with abortion was increased in all age groups. Women who had committed a suicide tended to come from lower social classes and were more likely to be unmarried than other women who had had a completed pregnancy.
The increased risk of suicide after an induced abortion indicates either common risk factors for both or harmful effects of induced abortion on mental health.
按妊娠类型确定与妊娠相关的自杀率。
登记联动研究。将育龄女性的自杀信息与芬兰出生、流产及医院出院登记信息相联系，以查明在生命最后一年自杀的女性中有多少人曾有过一次完整的妊娠。
来自芬兰的全国性数据。
1987 - 1994年期间自杀的女性。
有73例自杀与妊娠相关，占该年龄组女性自杀总数的5.4%。年自杀率平均为每10万人中有11.3例。与分娩相关的自杀率显著较低（5.9），而与流产（18.1）和人工流产（34.7）相关的自杀率显著高于总体人群。青少年中与分娩相关的风险更高，且所有年龄组中与人工流产相关的风险均有所增加。自杀女性往往来自社会阶层较低的群体，且比其他有过完整妊娠的女性更可能未婚。
人工流产后自杀风险增加表明两者存在共同的风险因素，或者人工流产对心理健康有有害影响。
