Demographic and socio-economic inequalities in subjective wellbeing: analysis of repeated cross-sectional health surveys in England 2010–2019.

Background Good subjective wellbeing (SWB) is a key societal aspiration. The study of SWB determinants is of increasing interest. The present study aimed to examine national inequalities in SWB, and trends in these inequalities, for England across five demographic (sex and age) and socio-economic (educational level, household income and living alone) characteristics. Method The relative index of inequalities (RII) and slope index of inequalities (SII) were calculated from repeated cross-sectional data from the Health Survey for England from 2010 to 2019 (excluding 2017 and 2018 as our outcome variable was not collected in these years), in a total of 90 236 participants aged 16+. SWB was assessed using the Warwick-Edinburgh Mental Well-being Scale (WEMWBS), treated as a dichotomous variable with high and low levels of SWB > 40 and ≤ 40, respectively. Results There were significant inequalities in SWB by income (RII from 1.086 to 1.116), educational level (RII from 0.893 to 0.941) and between people living alone or not (RII from 0.908 to 0.937). The RII and SII trends were not statistically significant. Conclusions Higher socio-economic status could play a protective role for SWB, and people in the most deprived socio-economic positions may be at higher risk for low SWB. These associations have remained stable over time. [ABSTRACT FROM AUTHOR]
