Without proper health insurance, an illness or accident can put them in a severe health condition and financial situation. The treatment and therapy bills can cause debt problems for whole families. Many factors are influencing to the decision of health insurance purchasing. In this paper, we introduce and examine the impacts of six factors affecting to students' willingness to buy health insurance, including price, quality of health service, payment policy, propagation, the role of the university, the competition with commercial health insurances by surveying with 120 respondents. The paper also determines the relationship between the profile of students and student’s action and the relationship between proposed factors and their willingness to buy. We find that, except the price, remain proposed factors influence significantly the willingness to buy health insurance of students in Thai Nguyen province. Further, the profile of students also affects significantly to their choice and decision. Base on results, we suggest that to improve the willingness to buy, the health insurance companies should improve their quality, extend payment mechanism, improve communication and the roles of university in orienting the purchasing decision.
