Using self-reported health as a social determinants of health outcome: a scoping review of reviews

Reducing disease prevalence rather than promoting health has long been the objective of significant population health initiatives, such as the social determinants of health (SDH) framework. However, empirical evidence suggests that people with diagnosed diseases often answer the self-reported health (SRH) question positively. In pursuit of a better proxy to understand, measure and improve health, this scoping review of reviews examines the potential of SRH to be used as an outcome of interest in population health policies. Following PRISMA-ScR guidelines, it synthesizes findings from 77 review papers (published until 11 May 2022) and reports a robust association between SDH and SRH. It also investigates inconsistencies within and between reviews to reveal how variation in population health can be explained by studying the impact of contextual factors, such as cultural, social, economic and political elements, on structural determinants such as socioeconomic situation, gender and ethnicity. These insights provide informed hypotheses for deeper explorations of the role of SDH in improving SRH. The review detects several gaps in the literature. Notably, more evidence syntheses are required, in general, on the pathway from contextual elements to population SRH and, in particular, on the social determinants of adolescents' SRH. This study reports a disease-oriented mindset in collecting, analysing and reporting SRH across the included reviews. Future studies should utilize the capability of SRH in interconnecting social, psychological and biological dimensions of health to actualize its full potential as a central public health measure.
