Factors Influencing Blood Donation among Young Saudi Arabian Adults: A Cross-Sectional Study to Inform Donor Recruitment and Retention Programs.

Objective: Blood donation is critical in Saudi Arabia due to high rates of sickle cell disease and thalassemia. Recent trends show a decline in the number of blood donors, threatening blood supplies for medical treatments. This study aims to identify factors that influence blood donation decisions and behaviors among young Saudi Arabian adults to develop strategies to enhance donation rates.

Methods: A cross-sectional study was conducted with 407 university students in Riyadh Province (Shaqra, Riyadh City, Al-Majmaah and Al-Duwadimi) and occurred from December 2022 to May 2023, using convenience sampling. Data were collected via online questionnaires and analyzed using logistic regression.

Results: Findings revealed a significant gender disparity in donation rates with males more likely to donate. Knowledge gaps were prevalent, especially regarding eligibility criteria. Support for organ donation, prior experience of receiving blood, and high levels of self-determined motivation positively associated with donation likelihood. Conversely, amotivation was a strong negative predictor of donation.

Conclusion: This study highlights the importance of educational interventions to address misconceptions about blood donation and tailor campaigns to enhance donor motivation. Strategies focusing on these aspects could improve the donor pool and ensure a stable blood supply for patients with blood disorders in Saudi Arabia.
