To determine if suicide attempts increased during the first year of the pandemic among young adolescents in Quebec, Canada.
We analyzed children aged 10-14 years who were hospitalized for a suicide attempt between January 2000 and March 2021. We calculated age-specific and sex-specific suicide attempt rates and the proportion of hospitalizations for suicide attempts before and during the pandemic and compared rates with patients aged 15-19 years. We used interrupted time series regression to measure changes in rates during the first (March 2020 to August 2020) and second (September 2020 to March 2021) waves and difference-in-difference analysis to determine if the pandemic had a greater impact on girls than boys.
Suicide attempt rates decreased for children aged 10-14 years during the first wave. However, rates increased sharply during the second wave for girls, without changing for boys. Girls aged 10-14 years had an excess of 5.1 suicide attempts per 10,000 at the start of wave 2, with rates continuing to increase by 0.6 per 10,000 every month thereafter. Compared with the prepandemic period, the increase in the proportion of girls aged 10-14 years hospitalized for a suicide attempt was 2.2% greater than that of boys during wave 2. The pattern seen in girls aged 10-14 years was not present in girls aged 15-19 years.
Hospitalizations for suicide attempts among girls aged 10-14 years increased considerably during the second wave of the pandemic, compared with boys and older girls. Young adolescent girls may benefit from screening and targeted interventions to address suicidal behavior.
在加拿大魁北克省，确定青少年在大流行的第一年是否尝试自杀的人数有所增加。
我们分析了 2000 年 1 月至 2021 年 3 月期间因自杀企图而住院的 10-14 岁儿童。我们计算了特定年龄和性别的自杀企图率以及大流行前后自杀企图住院的比例，并将这些比率与 15-19 岁的患者进行了比较。我们使用中断时间序列回归来衡量第一波（2020 年 3 月至 8 月）和第二波（2020 年 9 月至 2021 年 3 月）期间的变化，并通过差异分析来确定大流行对女孩的影响是否大于男孩。
在第一波期间，10-14 岁儿童的自杀企图率下降。然而，在第二波期间，女孩的自杀企图率急剧上升，而男孩的自杀企图率没有变化。第二波开始时，10-14 岁女孩每 10,000 人中有 5.1 次额外的自杀企图，此后每月每 10,000 人增加 0.6 次。与大流行前时期相比，第二波期间，10-14 岁女孩因自杀企图而住院的比例增加了 2.2%，而男孩的这一比例增加了 2.2%。10-14 岁女孩中出现的这种模式在 15-19 岁女孩中并不存在。
与男孩和年龄较大的女孩相比，在大流行的第二波期间，10-14 岁女孩因自杀企图而住院的人数大幅增加。青少年女孩可能需要接受筛查和有针对性的干预，以解决自杀行为问题。
