dc.description.abstractObjectives: To investigate whether a strong sense of coherence (SOC) modifes the association between low-income and oral and general health-related quality of life (OHRQoL and HRQoL, respectively) among a South Australian population sample; and to explore the main and interaction efects of income and SOC on OHRQoL and HRQoL. Methods: Baseline data from the Dental Care and Oral Health Study (DCOHS, a South Australian representative study, 2015–2016) were used for cross-sectional analysis (n=3,786). Four multivariable factorial ANOVA models were applied to assess the efect measure modifcation, main efects, and interaction of income and SOC on OHRQoL (measured using the OHIP-14) and HRQoL (measured using the EQ-5D-3L). Results: Income and SOC had small main efects on OHRQoL. Income had a small efect and SOC had an intermediate efect on HRQoL, meaning that individuals with strong SOC had better OHRQoL and HRQoL in all income categories. Also, high-income participants had better OHRQoL and HRQoL. The interaction between income and SOC was statistically signifcant on HRQoL. Among participants from low-income group, those with strong SOC had better OHRQoL (mean=8.8, 95% CI[7.9, 9.7]) and HRQoL (mean=1.1, 95% CI[1.0, 1.3]) than others with weak SOC (OHIP-14 mean=12.7, 95% CI[11.7, 13.6]) and (EQ-5D-3L mean=2.0, 95% CI[1.9, 2.2]). Conclusion: The findings showed the main effects and interaction between SOC and income on OHRQoL and HRQoL. Income had different effects on OHRQoL and HRQoL depending on whether SOC was strong or weak. Findings suggested that strong SOC modified the association between low-income and OHRQoL and HRQoL.
