DataSheet3_Temporal Dynamics of Socioeconomic Inequalities in COVID-19 Outcomes Over the Course of the Pandemic—A Scoping Review.docx

Objectives: International evidence of socioeconomic inequalities in COVID-19 outcomes is extensive and growing, but less is known about the temporal dynamics of these inequalities over the course of the pandemic.
Methods: We systematically searched the Embase and Scopus databases. Additionally, several relevant journals and the reference lists of all included articles were hand-searched. This study follows the PRISMA guidelines for scoping reviews.
Results: Forty-six studies were included. Of all analyses, 91.4% showed stable or increasing socioeconomic inequalities in COVID-19 outcomes over the course of the pandemic, with socioeconomically disadvantaged populations being most affected. Furthermore, the study results showed temporal dynamics in socioeconomic inequalities in COVID-19, frequently initiated through higher COVID-19 incidence and mortality rates in better-off populations and subsequent crossover dynamics to higher rates in socioeconomically disadvantaged populations (41.9% of all analyses).
Conclusion: The identified temporal dynamics of socioeconomic inequalities in COVID-19 outcomes have relevant public health implications. Socioeconomic inequalities should be monitored over time to enable the adaption of prevention and interventions according to the social particularities of specific pandemic phases.

研究目标：目前已有大量且不断增长的国际证据表明新冠疫情相关结局存在社会经济不平等，但针对疫情进程中此类不平等的时间动态变化特征，学界的认知仍较为有限。
研究方法：本研究系统检索了Embase与Scopus数据库；此外，我们还手工检索了多份相关期刊及所有纳入文献的参考文献列表。本研究严格遵循范围综述的PRISMA（Preferred Reporting Items for Systematic Reviews and Meta-Analyses，系统评价与荟萃分析优先报告条目）指南开展。
研究结果：本研究共纳入46项相关研究。在所有分析中，91.4%的结果显示，疫情进程中新冠疫情结局的社会经济不平等呈稳定或加剧趋势，社会经济地位弱势人群受影响最为严重。此外，本研究结果揭示了新冠疫情相关社会经济不平等的时间动态变化特征：此类不平等最初常表现为社会经济地位较高人群的新冠发病率与死亡率更高，随后出现交叉动态变化，即社会经济地位弱势人群的相关指标升至更高水平，该现象在所有分析中占比41.9%。
研究结论：本研究揭示的新冠疫情结局社会经济不平等的时间动态变化特征，具有重要的公共卫生实践意义。应持续开展社会经济不平等的长期监测，以便结合不同疫情阶段的社会特异性调整防控策略与干预措施。
