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.

Objective Although health inequalities in adolescence are well documented, the underlying mechanisms remain unclear. Few studies have examined the role of the family in explaining the association between the family’s socioeconomic position and adolescents’ self-rated health. The current study aimed to explore whether the association between socioeconomic position and self-rated health was mediated by familial determinants. Methods Using data from wave 2 of the”German Health Interview and Examination Survey for Children and Adolescents” (KiGGS) (1,838 female and 1,718 male 11- to 17-year-olds), linear regression analyses were conducted to decompose the total effects of income, education, occupational status, socioeconomic position index and adolescents’ subjective social status on self-rated health into direct effects and indirect effects through familial determinants (family cohesion, parental well-being, parental stress, parenting styles, parental obesity, smoking and sporting activity). Results A significant total effect of all socioeconomic position indicators on self-rated health was found, except for income in male adolescents. In female adolescents, more than 70% of the total effects of each socioeconomic position indicator were explained by familial mediators, whereas no significant direct effects remained. The most important mediator was parental well-being, followed by family cohesion, parental smoking and sporting activity. In male adolescents, the associations between income, parental education, the socioeconomic position index and subjective social status were also mediated by familial determinants (family cohesion, parental smoking, obesity and living in a single-mother family). However, a significant direct effect of subjective social status remained. Conclusion The analysis revealed how a family’s position of socioeconomic disadvantage can lead to poorer health in adolescents through different family practices. The family appears to play an important role in explaining health inequalities, particularly in female adolescents. Reducing health inequalities in adolescence requires policy interventions (macro-level), community-based strategies (meso-level) and programs to improve parenting and family functioning (micro-level).

Background International evidence shows a socially unequal burden of SARS-CoV-2 infections and COVID-19 outcomes across different socioeconomic groups. However, less is known about the temporal dynamics of socioeconomic inequalities in COVID-19 throughout the pandemic. We conducted a scoping review to systematically map and synthesize the available evidence. Methods We conducted a systematic literature search in Embase and Scopus with pre-defined eligibility criteria, including empirical research from 1 January 2020 to 24 August 2021. Additionally, several journals and the reference lists of all included articles were hand-searched to identify relevant studies. We used a standardized charting approach to extract relevant content and narratively synthesized the included evidence. The study follows the PRISMA guidelines for scoping reviews. Results From 8,011 identified records, we finally included 46 articles in the analysis. 50.0% of all included studies were conducted in the United States. The majority of all studies analyzed surveillance data (n = 44) and used area-based socioeconomic indicators on an ecological level (92.5%). The study results show temporal dynamics in COVID-19 inequalities, frequently initiated through higher outcome rates in more affluent populations and subsequent crossover dynamics to higher rates in more deprived populations (41.9%). Furthermore, 91.4% of the analyses show maintaining or worsening social inequalities in health with ongoing pandemic progression, which hit the most deprived populations the hardest. Conclusions The results show worsening social inequalities in COVID-19 over the course of the pandemic, with the most disadvantaged populations most affected during its progression. Targeted prevention and interventions, such as low-threshold testing and vaccination programs, infection protection for precarious jobs or living conditions, and targeted information are crucial to face socioeconomic inequalities throughout pandemics.
