背景：关于自杀风险的时间变化有相互矛盾的发现，很少有人在临床人群中研究这一现象。该研究调查了季节性和其他时间模式使用national data.Methods：数据73，591一般人群和19，318病人自杀死亡在1997年和2012年之间在英格兰收集通过国家机密调查自杀检查自杀率与一年中的月份，一周中的日子，和个别天的国家或宗教意义。自杀率在一年中连续几个月下降，有证据表明整个春季达到高峰。星期一与最高的自杀率有关，在患者人群中，这种影响似乎在50岁以上或独居的人中更为明显。圣诞节期间的自杀风险明显降低，尤其是女性。在普通人群中，元旦是自杀的高峰期。其他“特殊日子”与自杀发生率的变化无关。局限性：我们仅限于确定所研究变量之间的关联，无法探索因果机制。我们没有进行全面的多变量调整，在我们的回归models.Conclusions：有大量的自杀死亡的季节性和时间的变化，并出现了一些证据，在临床和一般人群在英格兰。临床服务应该意识到周末刚过就自杀的风险，特别是独居的人，以及在此期间可能需要更密切的监督。(C)© 2016 Elsevier B.V.版权所有。
Background: There have been conflicting findings on temporal variation in suicide risk and few have examined the phenomenon in clinical populations. The study investigated seasonal and other temporal patterns using national data.Methods: Data on 73,591 general population and 19,318 patient suicide deaths in England between 1997 and 2012 were collected through the National Confidential Inquiry into Suicide examining suicide rates in relation to month of the year, day of the week, and individual days of national or religious significance.Results: Suicide incidence fell over successive months of the year and there was evidence of an overall spring peak. Monday was associated with the highest suicide rates and in the patient population this effect appeared to be more pronounced in those aged over 50 or those who lived alone. Suicide risk was significantly lower during Christmas, particularly for women. There was a peak in suicide on New Year's Day in the general population. Other 'special days' were not associated with a change in suicide incidence. Limitations: We were limited to identifying associations between the variables investigated and were unable to explore causal mechanisms. We did not carry out comprehensive multi-variable adjustment in our regression models.Conclusions: There is substantial seasonal and temporal variation in suicide deaths, and there appears to be some evidence in the clinical as well as the general population in England. Clinical services should be aware of the risk of suicide just after the weekend, especially in people who live alone, and the potential need for closer supervision during this period.
