Factors influencing voluntary blood donation practice among university students of Bangladesh

Although voluntary blood donation among young people, particularly university students, is increasing and saving many valued lives, it is unclear which characteristics of the students have the most influence on their willingness to participate in voluntary blood donation. We aimed to identify the correlates that might influence voluntary blood donation practice. In total, 439 students from different universities in Bangladesh participated in this study. Data were collected using an e-questionnaire. To better understand students’ perception regarding voluntary blood donation, exploratory data analysis and the Pearson Chi-square test were performed. The degree of association of the possible risk factors was evaluated using odds ratios (OR) from a backward selection binary logistic regression model. 54 % (237) of the respondents voluntarily donated blood at least once. The odds of male students voluntarily donating blood were 7.28 (95 % CI: 4.14–12.78) times higher than their counterparts. University students who participated in various volunteer organizations were 2.43 [95 % CI: 1.49–3.96], p = 0.005) times and students, who had seen advertisements of blood donation on social media or a part of social media-based blood donation campaign were 4.72 [95 % CI: 2.57–8.65] times more likely to donate blood than their counterparts. The majority of the first-year students were discovered to be first-time blood donors. Moreover, BMI was also found to be significantly associated (positively) with blood donation practice. We found that females, students with lower BMI, and students who are not involved in any voluntary organization are less involved in voluntary blood donation.
