摘要

利用接合点回归分析法研究 2020 年 2 月 19 日至 2022 年 9 月 5 日国家疫苗接种计划前后 COVID-19 的死亡率趋势。本研究对 2020 年 2 月 19 日至 2022 年 9 月 5 日期间每月收集的伊朗 COVID-19 确诊死亡数据进行了连接点回归分析。在伊朗全国接种疫苗后，每月新增 COVID-19 死亡病例呈下降趋势。从大流行开始到第 19 个月，每月变化的百分比为 6.62%（95% CI：1.1，12.4），呈上升趋势。从第 19 个月到第 31 个月末，死亡率呈下降趋势，月变化百分比为-20.05%（95% CI：-8.3，-30.3）（P=0.002）。每月变化的平均百分比为-5%，95% CI 为（-10.5，0.9）。与其他卫生措施（如隔离、戴口罩、洗手、社交疏远等）一起，全民接种疫苗可显著降低 COVID-19 的死亡率。

COVID-19 mortality trends before and after the national vaccination program in Iran: A joinpoint regression analysis

To investigate the trend of mortality by COVID-19 before and after the national vaccination program using joinpoint regression analysis from 19 February 2020 to 5 September 2022. In the present study, a joinpoint regression analysis of monthly collected data on confirmed deaths of COVID-19 in Iran from February 19, 2020 to September 5, 2022 was performed. After national vaccination in Iran, the trend of new monthly deaths due to COVID-19 was decreasing. The percentage of monthly changes from the beginning of the pandemic to the 19th month was 6.62% (95% CI: 1.1, 12.4), which had an increasing trend. From the 19th month to the end of the 31st month, the mortality trend was decreasing, and the percentage of monthly changes was −20.05% (95% CI: −8.3, −30.3) (P=0.002). The average percentage of monthly changes was −5% with a 95% CI of (−10.5, 0.9). Along with other health measures, such as quarantine, wearing a mask, hand washing, social distancing, etc., national vaccination significantly reduces the mortality rate of COVID-19.
