| Research Abstract |
The research shows the association of socioeconomic status (SES) such as income, educational attainment, employment, with health behaviors, preventive service use, circulatory disease risk factors, nutrition, poor mental health, somatic complaints, and the use of medical care. The associations between SES and health were mediated by health behaviors and inner and outer psychosocial factors. Social class and related psychosocial factors may affect brain function. Among people with low social class, brain and somatic responses may be blunted in risky decision making, with weakened typical reactions in prefrontal cortex, insula, striatum, and autonomic nervous system. Psychological reactions associated with social class were found to be associated with abnormal gene expressions related to immune and inflammation.
