Abstract

OBJECTIVE

In the first year of the COVID-19 pandemic, gun violence (GV) rates in the United States (US) rose by 30%. We estimate the relative risk of GV in the US in the second year compared to the first year of the pandemic, in time and space.

METHODS

Daily police reports of gun-related injuries and deaths in the 50 states and the District of Columbia from March 1, 2020, to February 28, 2022, were obtained from the GV Archive. Generalized linear mixed-effects models in the form of Poisson regression analyses were utilized to estimate state-specific rates of GV.

RESULTS

Nationally, GV rates during the second year of the pandemic (March 1, 2021, through February 28, 2022) remained the same as that of the first year (March 1, 2020, through February 28, 2021) (Intensity Ratio = 0.996; 95% CI 0.98, 1.01; = 0.53). Nevertheless, hotspots of GV were identified. Nine (18%) states registered a significantly higher risk of GV during the second year of the pandemic compared to the same period in the first year. In 10 (20%) states, the risk of GV during the second year of the pandemic was significantly lower compared to the same period in the first year.

CONCLUSION

GV risk in the US is heterogeneous. It continues to be a public health crisis, with 18% of the states demonstrating significantly higher GV rates during the second year of the COVID-19 pandemic compared to the same timeframe 1 year prior.

摘要

目的

在 COVID-19 大流行的第一年,美国(美国)的枪支暴力(GV)率上升了 30%。我们估计大流行第二年与第一年相比,美国 GV 的相对风险,在时间和空间上。

方法

从 2020 年 3 月 1 日至 2022 年 2 月 28 日,从 50 个州和哥伦比亚特区获得了与枪支有关的伤害和死亡的每日警方报告,这些报告来自 GV 档案。利用广义线性混合效应模型形式的泊松回归分析来估计州特定的 GV 率。

结果

在大流行的第二年(2021 年 3 月 1 日至 2022 年 2 月 28 日),全国 GV 率与第一年(2020 年 3 月 1 日至 2021 年 2 月 28 日)相同(强度比= 0.996;95%CI 0.98, 1.01;P= 0.53)。尽管如此,仍确定了 GV 的热点地区。九个(18%)州在大流行的第二年登记的 GV 风险明显高于第一年同期。在 10 个(20%)州,大流行第二年的 GV 风险明显低于第一年同期。

结论

美国的 GV 风险具有异质性。它仍然是一个公共卫生危机,有 18%的州在 COVID-19 大流行的第二年与前一年同期相比,GV 率明显更高。
