The aim of this article was to study repeated suicidal behaviour in a low-incidence population to elucidate robust risk factors.
A cohort of first-ever suicide attempters from 1960 to 1982 on the Faroe Islands was followed up for a minimum of 20 years. The cohort was initially characterized in psychiatric and social terms.
The incidence of suicidal behaviour for the cohort years (age 15 years and older) was 37.9 per 100,000 per year (95% confidence interval 31.5-45.1). It was associated, as expected, with gender, age, residence, marital status, occupation, diagnosis, previous psychiatric admission, alcohol intoxication and the method and planning of the act. Factors of the index episode predicting repetition at 5 years were gestures and alcohol intoxication and at 20 years were physical methods, suicide letter and alcohol intoxication.
Alcohol intoxication and the level of determination behind the suicide attempt emerge as targets for prevention. Alcohol intoxication at the initial episode seems to be a strong long-term as well as short-term risk factor.
本文旨在研究低发病率人群中的反复自杀行为，以阐明可靠的风险因素。
对1960年至1982年法罗群岛首次自杀未遂者组成的队列进行了至少20年的随访。该队列最初从精神病学和社会学角度进行了特征描述。
该队列年份（15岁及以上）的自杀行为发生率为每年每10万人37.9例（95%置信区间31.5 - 45.1）。正如预期的那样，它与性别、年龄、居住地、婚姻状况、职业、诊断、既往精神病住院史、酒精中毒以及自杀行为的方式和计划有关。预测5年后复发的首次发作因素是自杀姿态和酒精中毒，而预测20年后复发的因素是躯体方式、遗书和酒精中毒。
酒精中毒和自杀未遂背后的决心程度成为预防的目标。首次发作时的酒精中毒似乎是一个强大的长期和短期风险因素。
