Abstract

This study examined the association between public health restrictions and the point prevalence of home birth in Alberta between January 1, 2017- December 31, 2021 using administrative health data. Monthly home birth prevalences were examined over the pre-pandemic (n = 161 225), pandemic (n = 77 563), and pandemic wave periods via interrupted time series analysis. Logistic regression modelling estimated the association between home birth and monthly averaged Government Response Stringency Index (GSRI). During the pandemic, home birth prevalence increased (pre-pandemic: 24.82, P < 0.001; slope: -0.02, P = 0.332; pandemic: level change:7.51, P = 006; slope change: -0.40, P = 0.006. Only the first pandemic wave found an association between GSRI and the probability of home birth (OR:1.17; 95%CI:1.03-1.33).

新冠肺炎公共卫生限制对艾伯塔省家庭分娩趋势的影响：一项观察性回顾性队列研究

本研究利用行政卫生数据，研究了2017年1月1日至2021年12月31日期间艾伯塔省公共卫生限制与家庭分娩点流行率之间的关系。通过中断时间序列分析，研究了大流行前（n = 161 225）、大流行期（n = 77 563）和大流行波期间的每月家庭出生流行率。Logistic回归模型估计了家庭出生与每月平均政府反应严格指数（GSRI）之间的关系。大流行期间，在家分娩的流行率增加(大流行前：24.82,P < 0.001；斜率：-0.02,P = 0.332；大流行：水平变化：7.51,P = 006；斜率变化：-0.40,P = 0.006。只有第一波大流行发现GSRI与家庭分娩概率之间存在关联(OR:1.17；95%置信区间:1.03—-1.33)。
