This paper uses DHS sample data on Swaziland to investigate the relationship between education and health by focusing on education level (defined by number of years of schooling) and quality of HIV/AIDS knowledge and their effects on risky sexual behavior. An ordered probit model is used to address the quality of HIV/AIDS knowledge, using a 4 level scale, where knowledge ranges from zero/no knowledge to excellent knowledge. A regular probit model is used to analyze the effect of the quality of HIV/AIDS knowledge on various factors used as a measure of risky sexual behavior. The main findings are that the education level is positively correlated to the quality of HIV/AIDS knowledge. Yet, a higher quality of HIV/AIDS knowledge does not always result in safe sexual behaviors. It does not influence the likelihood of having multiple sexual partners in a statistically significant way, but does increase the likelihood of condom use.
