Proposed conceptual framework of relations between factors associated with ethnic inequalities in sexual health outcomes
Socioeconomic factors, substance use, and mental health related factors can directly influence sexual behaviours and sexual health outcomes. Substance use can also mediate the relationship between socioeconomic factors and sexual behaviours. Sexual behaviours are proximate determinants of sexual health outcomes. Thus, ethnic variations in sexual health markers are the biological embodiment of all these exposures. STI=sexually transmitted infection. *According to ecosocial theory, social inequalities in health are the biological embodiment of exposures arising from societal and ecological contexts mediated by physiology, behaviour, and gene expression (Krieger 2012).10
