73 percent of patients reporting use of self-medication to deal with illness and most people procure medication for self-medication at pharmacists The common practice of self-medication has both positive and negative aspects In cases of common illness, such as coughs or colds, self-medication may be rational behaviour in terms of convenient, time saving and cheap if patients have sufficient knowledge about common non-prescription drugs But in cases of more serious disease, requiring the use of antibiotics or steroids, or in cases of special status such as pregnancy, babies, people with TIEU LUAN MOI download : skknchat@gmail.com drug allergies, the treatment without consultation of medical professionals can lead to harmful consequences In the latter cases, self-medication accompanied the lack of ability or awareness of the need to read the drug information lead to a risky of wasting money, status of sickness may be more serious The negative sides of self-medication not only affect the individuals but also the community The large scale drug resistance in the community of Vietnam has increased and reached epidemic levels (Sam, 1993) The future potency of drug for all users is reduced, which has lead to increasing the amount of treatment failures, and as the result, leading to longer and more severe illness and demand for more expensive drugs This result has increased financial burden on the poor and those without any medical knowledge a further reduction in equity (WHO, 2001a) The promotion of the rational drugs use to minimize the negatives effects on the public health when the self-medication practice is prevalence in Vietnam is the emerging concern of health policy makers Designing effective interventions can not be done without understanding factors impact on selfmedication behaviour of people In this study we focus on finding out the influence of educational level on self-medication behaviour of patients in Ho Chi Minh city, one of the biggest city of the country TIEU LUAN MOI download : skknchat@gmail.com 1.2 RESEARCH OBJECTIVE, RESEARCH QUESTION AND RESEARCH HYPOTHESIS Research objective On the demand side, the knowledge, attitudes, and education of an individual are important determinants in the decision to seeking health care The most important purpose of this study is to examining the impacts of educational level of the adults on their self-medication when being illness The influences of other sociodemographic factors, attributes of health care provider on self-medication behaviour of patients in Ho Chi Minh city are also included in order to support the health policy makers who are interested in improving the appropriate access of self-medication in public Research Question and Research Hypothesis It's realised that education level enhances the ability of accessing and criticising information of people Therefore, an individual with high educational level is expected that might have high self-confidence about his medical knowledge which results in having more self-medication than lower educational person Hence, this dissertation attempts to answer the question: - Are adult individuals with higher years of schooling more likely to be self-medicated facing typical diseases?
