The weekly fluctuation in suicide rates is influenced by several factors including sex, psychiatric illness and alcohol dependence. The purpose of this study is to explore the impact of current alcohol use on suicid.
Data on sex, date of death, results of blood and/or urine alcohol tests and history of alcohol dependence in suicide victims over the 1997-2002 period were retrieved from a forensic database in two cities in Chuvash Republic.
Over the six-year study period, 1,379 suicides were committed, 59% of them under the influence of alcohol. The peak incidence for men and women regardless of previous alcohol consumption was on Wednesdays and Mondays, respectively. The overall suicide rate was highest on Mondays and lowest on Thursdays. Both sexes were less likely to commit suicide during holidays than on weekends or workdays while intoxicated with alcohol.
In this urban sample, the distribution of suicide across weekdays only partly followed the international pattern. The peak incidence of suicide showed sex difference, with the highest incidence for women on Mondays and for men on Wednesdays. The higher suicide rate on workdays might be accounted for by work-related stress, while the lower rate on weekends could be explained that people usually drink alcohol in the comforting company of family or friends, which reduces psychological tension and suicidal ideation. The majority of men consumed alcohol before committing suicide, regardless of the day of the week, while this observation was true for women only on Fridays and Sundays. Alcohol consumption greatly contributes to suicidal behavior in Chuvash Republic.
自杀率的周波动受多种因素影响，包括性别、精神疾病和酒精依赖。本研究旨在探讨当前酒精使用对自杀的影响。
从两个城市的法医数据库中检索了 1997-2002 年期间自杀者的性别、死亡日期、血液和/或尿液酒精检测结果以及酒精依赖史的数据。
在六年的研究期间，有 1379 人自杀，其中 59%的人饮酒后自杀。无论之前是否饮酒，男性和女性的峰值发病日均分别为星期三和星期一。整体自杀率在星期一最高，星期四最低。男女在节假日醉酒时自杀的可能性均低于周末或工作日。
在这个城市样本中，自杀在工作日的分布仅部分符合国际模式。自杀的高发时段存在性别差异，女性在星期一最高发，男性在星期三最高发。工作日自杀率较高可能是由于工作相关的压力所致，而周末的自杀率较低可能是因为人们通常在家人或朋友的陪伴下饮酒，这可以减轻心理紧张和自杀意念。大多数男性在自杀前饮酒，无论星期几都是如此，而这种观察仅适用于女性在星期五和星期天。在楚瓦什共和国，酒精消费极大地促成了自杀行为。
