Abstract
Objective: While social status and health have been investigated, there is less focus on the effects of objective and subjective social status and psychosocial factors. This study aimed to investigate oral health impacts by subjective social status (SSS) and psychosocial predictors stratified by subjective social status. Methods: A random cross-sectional sample of 45-54-year old South Australians was surveyed in 2004-05. Oral health impact was assessed using OHIP-14. Socio-economic status was determined using objective (income) and subjective (McArthur scale) measures. Psychosocial variables comprised social support, health self-efficacy, coping and affectivity. Results: Responses were collected from 986 persons (response rate=44.4%). Lower SSS was more frequently observed in the low (70.2%) than high-income group (28.5%). Lower SSS was associated (p⟨0.05) with lower education, social support, health competence, and coping, but higher negative affect within income groups. The interaction of SSS and income showed OHIP was consistently lower at high SSS regardless of higher or lower income, but at low SSS, OHIP was higher (p⟨0.05) in the lower than higher income group. Conclusions: SSS was associated with income. Their interaction indicated low SSS in combination with low income was associated with higher oral health impacts.
