To assess the seroprevalence of infection-acquired SARS-CoV-2 and the mental health of school/daycare staff in the months after reopening of schools in Montreal, Quebec (Canada) in the Fall of 2020 and whether these varied by school and participant characteristics.
A cross-sectional design based on a convenience sample of schools/daycares and staff was used as the originally planned longitudinal design was no longer feasible due to obstacles in recruitment, for example, teacher's strike.
Forty-nine schools/daycares in four Montreal neighbourhoods from March to October 2021.
Three-hundred and sixty-two participants completed both questionnaires and serology tests.
SARS-CoV-2 seroprevalence and prevalence of anxiety, depression, resilience and burnout/emotional exhaustion.
The seroprevalence estimate made representative to the Quebec population of educators was 8.6% (95% CI 5.2 to 13.0). The adjusted seroprevalence in high school was 20% that of elementary school (aRR=0.20, 95% CI 0.07 to 0.58). Thirty per cent of seropositive staff were exposed to a household member with confirmed COVID-19. Prevalence of high emotional exhaustion/burnout was 35%, 44% and 53% in daycare, elementary school and high school staff, respectively. However, moderate/severe anxiety and depression and low resilience did not exceed 18%. After adjusting for confounders, being very afraid of catching COVID-19 at school was associated with moderate-severe anxiety, moderate-severe depression and high emotional exhaustion (aRR=4.4, 95% CI 2.2 to 8.9; aRR=2.8, 95% CI 1.5 to 5.4; aRR=2.2, 95% CI 1.6 to 3.0, respectively).
The seroprevalence, anxiety and depression among school/daycare staff were comparable to the reported levels in the adult population of Quebec. The prevalence of emotional exhaustion/burnout was high across all school levels and exceeding the average across all occupations in the USA and in teachers in Germany.
评估 2020 年秋季魁北克省（加拿大）蒙特利尔市学校重新开放后，感染获得的 SARS-CoV-2 血清阳性率和学校/日托工作人员的心理健康状况，以及这些情况是否因学校和参与者特征而有所不同。
基于学校/日托机构和工作人员的便利样本进行的横断面设计，因为招募方面的障碍（例如教师罢工），最初计划的纵向设计不再可行。
2021 年 3 月至 10 月，来自蒙特利尔四个社区的 49 所学校/日托机构。
362 名参与者完成了问卷调查和血清学检测。
SARS-CoV-2 血清阳性率以及焦虑、抑郁、韧性和倦怠/情绪衰竭的患病率。
针对魁北克省教育工作者的代表性血清阳性率估计为 8.6%（95%置信区间 5.2 至 13.0）。高中的调整后血清阳性率是小学的 20%（调整后比值比[aRR]=0.20，95%置信区间 0.07 至 0.58）。30%的血清阳性工作人员曾与确诊 COVID-19 的家庭成员接触。日托、小学和高中工作人员中，高情绪衰竭/倦怠的患病率分别为 30%、44%和 53%。然而，中度/重度焦虑和抑郁以及低韧性的比例均不超过 18%。在校内非常担心感染 COVID-19 与中度/重度焦虑、中度/重度抑郁和高情绪衰竭相关（调整后比值比[aRR]=4.4，95%置信区间 2.2 至 8.9；aRR=2.8，95%置信区间 1.5 至 5.4；aRR=2.2，95%置信区间 1.6 至 3.0）。
学校/日托机构工作人员的血清阳性率、焦虑和抑郁与魁北克省成年人群报告的水平相当。所有学校层面的情绪衰竭/倦怠患病率均较高，超过了美国所有职业和德国教师的平均水平。
