A Cross Sectional Study on Knowledge, Attitude and Practice of Hepatitis B Vaccination Among Medical Students in Malaysia
Transmission of HBV commonly occurs through exposure to bodily fluids, therefore putting health care workers at a higher risk of becoming infected. It is important for the medical students to have a good knowledge, attitude and practice regarding Hepatitis B vaccination. A questionnaire based analytical cross sectional study was used to conduct the study of knowledge, attitude and practice of hepatitis B vaccination among the medical students of private medical college in Malaysia. Participants of this study comprised of 3rd and 4th academic year students who have enrolled for MBBS in private medical college in Malaysia. The sample size of this research is 171 students. The questionnaire consisted of 4 sections, which are demographic details, attitude and practice of Hepatitis B vaccination. For qualitative data such as gender, race and socioeconomic status are calculated by using frequency, percentage and mode. The hypothesis tested by applying the Unpaired t test, ANOVA and binary logistic regression, odds ratio and 95% CI were used to measure the associations. In this research, 95.91% of the students were vaccinated against Hepatitis B (HBV) and 74.85% of the students had full doses (3 doses) of HBV vaccine. 92.4% of the students had moderate to good attitude and knowledge regarding HB vaccination. There is no significant association between gender (P=0.565), ethnicity (P=0.135), socioeconomic status (P=0.593) and knowledge (P=0.066) with practice of HBV vaccination. Female has 3.69 attitudes percentage score higher than male with a significant association (P<0.001). Chinese has higher attitude mean score (mean=85.53%) compared with Indian (mean=82.42%), Malay (mean=73.79%) and other ethnicities (mean=83.28%), this has significant association (P=0.002). Lower (mean=64.81%) socioeconomic status also shows lower attitude mean score compared with upper class (mean=82.37%), upper middle class (mean=83.09%), lower middle class (mean=82.28%) and working class (mean=81.48%), this has significant association (P=0.001). There is significant association between attitude and knowledge of HBV vaccination (P=0.002), students with good attitude mean score were 1.09 more likely to have better practice of Hepatitis B vaccination. The medical students who were not completed the full doses of Hepatitis B vaccination requirement should be educated on the importance of hepatitis b vaccination. We recommend the future studies to collect responses from all academic years so that the study would be of higher significance.
