to evaluate the impact on total mortality of the COVID-19 pandemic in Italy, by country of birth.
historic cohort study based on administrative databases.
the study is based on subjects included in the Base Register of Individuals of the Italian National Institute of Statistics on 01.01.2019, aged 35-64 years, and followed-up until 31.07.2021.
age-standardized mortality rates were computed to analyse trends in overall mortality by country of birth grouped in three categories: 1. Italy and other high developed countries; 2. European countries with strong migratory pressure (EU-SMP); 3, non-European countries with strong migratory pressure (non-EU-SMP). Variations in mortality rates during the pandemic (March 2020-July 2021) with respect to the pre-pandemic period (January 2019-February 2020) were measured and compared across groups using mortality rate ratios (MRR) estimated by Poisson regression models, separately for men and women.
the cohort includes 26,199,241 individuals, of whom 172,847 died during the follow-up. Over the whole period, mortality was consistently lower in individuals born in non-EU-SMP countries as compared to those born in Italy and other high developed countries. During the first pandemic wave (March-April 2020), individuals born in non-EU-SMP countries had higher excesses as compared to those born in Italy or other high developed countries (MRRs: 1.42 vs 1.28 in men and 1.30 vs 1.11 in women). Similar results were observed during the pandemic period October 2020-April 2021, when the MRRs were 1.37 vs 1.20 in men and 1.30 vs 1.11 in women. In the same period, the excess mortality among individuals born in EU-SMP did not significantly differ from that observed among those born in Italy and other high developed countries.
in Italy, excess mortality during the COVID-19 pandemic was higher among immigrants born in non-EU-SMP countries as compared to the native population and immigrants born in high developed countries.
按出生国家评估意大利新冠疫情对总死亡率的影响。
基于行政数据库的历史性队列研究。
该研究基于2019年1月1日意大利国家统计局个人基本登记册中年龄在35至64岁之间的受试者，并随访至2021年7月31日。
计算年龄标准化死亡率，以分析按出生国家分组的总体死亡率趋势，分为三类：1. 意大利和其他高度发达国家；2. 有强大移民压力的欧洲国家（欧盟 - SMP）；3. 有强大移民压力的非欧洲国家（非欧盟 - SMP）。使用泊松回归模型估计的死亡率比（MRR）来衡量疫情期间（2020年3月至2021年7月）与疫情前时期（2019年1月至2020年2月）死亡率的变化，并按性别分别在各组之间进行比较。
该队列包括26,199,241人，其中172,847人在随访期间死亡。在整个期间，与出生在意大利和其他高度发达国家的人相比，出生在非欧盟 - SMP国家的人的死亡率一直较低。在疫情的第一波（2020年3月至4月）期间，与出生在意大利或其他高度发达国家的人相比，出生在非欧盟 - SMP国家的人超额死亡率更高（男性MRR：1.42对1.28，女性MRR：1.30对1.11）。在2020年10月至2021年4月的疫情期间也观察到类似结果，此时男性MRR为1.37对1.20，女性MRR为1.30对1.11。在同一时期，出生在欧盟 - SMP国家的人的超额死亡率与出生在意大利和其他高度发达国家的人所观察到的超额死亡率没有显著差异。
在意大利，与本国人口和出生在高度发达国家的移民相比，出生在非欧盟 - SMP国家的移民在新冠疫情期间的超额死亡率更高。
