Knowledge, attitudes, and practices about hepatitis B among medical and dental students of Karachi

Objective: The objective of the study was to assess the knowledge, attitude, and practices (KAP) about Hepatitis B virus (HBV) among the students of medical and dental colleges of Karachi. Methodology: The cross-sectional study was conducted in five medical and dental colleges of Karachi. Students of the 3rd, 4th, and final year were invited to join the study. The questionnaire included sociodemographic information followed by three sections evaluating the knowledge, attitudes, and practices regarding HBV. Twenty-nine questions were related to knowledge, 11 for attitude, and 4 for practices. Pearson's Chi-square test/Fisher's Exact test and Spearman correlation were utilized to find the association and correlation of knowledge, attitudes, and practices with independent variables. Results: Three hundred and seventy-nine students participated in the study. Two hundred and nine of them (78.9%) were females and 253 (66.8%) students were medical students. Ninety-five percent of the students correctly responded of the causative organism of HBV. Knowledge of MBBS and BDS students for transmission of HBV were significantly different for the questions: “mother to child,” coughing and sneezing' and “kissing.” Almost all the responses regarding complications due to HBV (respiratory failure, stroke, congestive heart failure liver, cirrhosis, colorectal cancer, and spine and bone fracture) received more than 90% of correct answers. In response to contraindication factors for HBV, only “extreme of ages” showed a significant difference between the genders. The percentage of poor, moderate, and good knowledge were 17.4%, 53%, and 29.6% respectively. About 60% of students indicated that they have gone through screening for HBV. About 20% of students indicated that they had experience of needle injury and only 43% of them taken postexposure prophylactic measures. Conclusion: Study revealed that the KAP of medical and dental students of Karachi are satisfactory and have been improved. However, few elements need to be focused in curricula and workshops for further improvement.
