This study seeks to understand the relationship between socioeconomic
status (SES) and self-reported indicators of physical and mental healt
h in an urban Third World context. The data come from a probability sa
mple of 654 adult residents of Georgetown, Guyana. There is a signific
ant inverse association between formal education and morbidity for fou
r of the six measures of health status. In this research the extent to
which self-concept, health behaviors, stress and social ties are link
ed to health status and SES, and can explain SES differences in health
status is explored. Psychosocial factors, especially the self-concept
measures (self-esteem and mastery) play a moderate role in accounting
for educational differences in health status.
