个人对COVID-19感染风险的脆弱性因其健康状况、社会经济和生活环境而异，这也会影响实施非药物干预措施的有效性。在本研究中，我们使用2019年具有全国代表性的南非家庭综合调查的数据分析了COVID-19脆弱性中与社会经济相关的不平等现象。我们制定了COVID-19脆弱性指数，其中包括COVID-19暴露和易感性的健康和社会风险因素。浓度曲线和浓度指数用于衡量COVID-19脆弱性的社会经济相关不平等。然后利用新中心影响函数回归来分解解释COVID-19脆弱性中与社会经济相关的不平等的因素。浓度指数估计值均为负且极显著（p < 0.01），表明COVID-19脆弱性更集中在穷人中。根据分解分析，较高的收入和教育水平显著（p < 0.01）正向影响降低与社会经济相关的COVID-19脆弱性。居住在城市地区、黑人和老年人都对增加与社会经济相关的COVID-19脆弱性有显著（p < 0.01）的积极影响。我们的研究结果有助于更好地了解南非社会定义的covid -19弱势群体，以及对未来大流行防范计划的影响。
Individuals’ vulnerability to the risk of COVID-19 infection varies due to their health, socioeconomic, and living circumstances, which also affect the effectiveness of implementing non-pharmacological interventions (NPIs). In this study, we analysed socioeconomic-related inequalities in COVID-19 vulnerability using data from the nationally representative South African General Household Survey 2019. We developed a COVID-19 vulnerability index, which includes health and social risk factors for COVID-19 exposure and susceptibility. The concentration curve and concentration index were used to measure socioeconomic-related inequalities in COVID-19 vulnerability. Recentred influence function regression was then utilised to decompose factors that explain the socioeconomic-related inequalities in COVID-19 vulnerability. The concentration index estimates were all negative and highly significant (p < 0.01), indicating that vulnerability to COVID-19 was more concentrated among the poor. According to the decomposition analysis, higher income and education significantly (p < 0.01) positively impacted lowering socioeconomic-related COVID-19 vulnerability. Living in an urban region, being Black, and old all had significant (p < 0.01) positive impacts on increasing socioeconomic-related COVID-19 vulnerability. Our findings contribute to a better understanding of socially defined COVID-19-vulnerable populations in South Africa and the implications for future pandemic preparedness plans.
