As part of the National Suicide Prevention Project in Finland, a nationwide psychological autopsy study, all suicide victims (n = 1397) over a 12-month period were investigated concerning factors associated with any variation in suicide frequency between weekdays and weekends. In particular, employment status was expected to have influenced the weekly pattern of alcohol misuse, and thereby to have caused clustering of suicides at weekends among the employed. Among suicide victims who had misused alcohol, those in employment were significantly more likely to have committed suicide during the weekend that those without work (52% vs. 34%, p < 0.001). In logistic regression analysis, employment was the only independent variable significantly associated with suicide at the weekend. According to forensic chemical analysis, those classified as misusers had frequently used alcohol at the time of suicide, regardless of the weekday, and slightly more often if employed. The clustering of suicides at weekends among employed alcohol misusers is probably explained by a weekly pattern in the use of alcohol, which suggests that besides the established risk factors for suicide among alcohol misusers, the act of using alcohol per se also contributes to the suicidal act.
作为芬兰全国预防自杀项目的一部分，一项全国性心理解剖研究对12个月期间的所有自杀受害者（n = 1397）进行了调查，以了解与工作日和周末自杀频率差异相关的因素。特别是，就业状况预计会影响每周酒精滥用模式，从而导致就业者中周末自杀事件的聚集。在滥用酒精的自杀受害者中，就业者在周末自杀的可能性显著高于无工作者（52%对34%，p < 0.001）。在逻辑回归分析中，就业是与周末自杀显著相关的唯一独立变量。根据法医化学分析，无论工作日如何，被归类为滥用者的人在自杀时经常饮酒，就业者饮酒的频率略高。就业的酒精滥用者中周末自杀事件的聚集可能是由酒精使用的每周模式所解释的，这表明除了酒精滥用者中已确定的自杀风险因素外，饮酒本身的行为也促成了自杀行为。
