Suicides are predicted to drop in the acute phase of any crisis that poses a threat to the entire population, though data on this are inconsistent. A pandemic is the most severe global crisis one can imagine. There is an urgent need to identify objective trends in suicide rates across countries and populations in a real-time manner in order to be better informed regarding prospects and adaptation of preventive strategies.
To evaluate suicidal behaviour in a metropolis immediately after the introduction of severe containment measures due to the pandemic.
Cases of completed suicides in St. Petersburg were obtained from the local city Bureau of Forensic Medical Examinations for the period 1 January 2016 to 31 July 2020. Data were accurately collected and monthly frequencies per 100,000 of the population in April-May 2020 (introduction of the most severe stay at home measures) were compared with corresponding data from 2016-2019. Confidence intervals were calculated according to Wilson.
Suicide frequencies in the population of St. Petersburg in April 2020 did not go up, in contrast, they were 30.3% lower than the average for the previous four years. The decrease in April was more pronounced in males than in females (36.3% and12.4%, respectively). When looking at age groups it was found that the biggest drop in suicides was in older males ( 55 years). In this group, suicide indices were 58.5% lower than average for the previous four years. However, in females, there was a 50% rise in suicides in June, while in young males (15-34 years) there was an 87.9% rise in May. Total number of suicides for the first half of 2020 was very close to the average seen in previous years. None of the registered changes were statistically significant.
The analysis is preliminary and does not account for possible seasonality, however, we consider that the reduction in completed suicides immediately after crisis exposure deserves attention. It supports views that in the acute phase of the crisis, suicidal behaviour may decline, which may be quickly replaced by a rise. Such a rise in females and younger males points on possible risk groups and requires a response from society. More studies are needed to have a clearer picture of suicide dynamics in Russia during the different waves of the pandemic, and prevention should be prioritized regardless of the tendencies.
在任何对全体人口构成威胁的危机急性期,自杀率预计会下降,不过相关数据并不一致。大流行是人们所能想象的最严重的全球危机。迫切需要实时确定各国和各人群自杀率的客观趋势,以便更好地了解预防策略的前景和适应性。
评估在因大流行而实施严格管控措施后,一个大都市内的自杀行为。
从圣彼得堡当地市法医局获取2016年1月1日至2020年7月31日期间的自杀既遂案例。准确收集数据,并将2020年4月至5月(实施最严格的居家措施期间)每10万人中的月度发生率与2016 - 2019年的相应数据进行比较。根据威尔逊方法计算置信区间。
2020年4月圣彼得堡居民的自杀发生率并未上升,相反,比前四年的平均水平低30.3%。4月男性的下降幅度比女性更明显(分别为36.3%和12.4%)。查看年龄组时发现,自杀下降幅度最大的是老年男性(55岁及以上)。在该年龄组中,自杀指数比前四年的平均水平低58.5%。然而,在女性中,6月自杀率上升了50%,而在年轻男性(15 - 34岁)中,5月自杀率上升了87.9%。2020年上半年的自杀总数与前几年的平均水平非常接近。所有登记的变化均无统计学意义。
该分析是初步的,未考虑可能的季节性因素,然而,我们认为危机暴露后自杀既遂案例的减少值得关注。这支持了以下观点,即在危机急性期,自杀行为可能会下降,但可能很快会被上升所取代。女性和年轻男性的这种上升指出了可能的风险群体,需要社会做出反应。需要更多研究以更清楚地了解俄罗斯在大流行不同阶段的自杀动态,并且无论趋势如何,预防都应优先考虑。
