Background: Blood donations are an important need worldwide. In Peru, only 10% of donations are voluntary, of which only a quarter are repeat donors. Repeat donations are crucial to maintaining a safe and adequate blood supply. Social media presents a unique opportunity to promote blood donation, because of its increasing use and its prior successes in promoting positive health-related behaviors. Objectives: The present study aims to develop and evaluate a social media intervention - Facebook® and WhatsApp® - sending promotional messages to increase repeat blood donations in voluntary first-time donors. It also assesses the status of change according to the Trastheoretical Model of Change, before and after the intervention, as well as the difference between them. Methods: This study was a randomized controlled trial. A sample of 212 participants was proposed, however, 160 first-time donors were enrolled and divided into two groups (intervention and control). Participants in the intervention group received messages promoting blood donation through social media once every 5 days for six months. Participants in the control group only received two messages, one right after the enrollment and the second one four months after completing their first blood donation. Results: Repeat blood donation was confirmed in six participants of the intervention group (7.50%) and two of the control group (2.50%). Participants report a higher repeat blood donation incidence in the intervention group (13.75%) compared to the control group (7.50%). However, both differences were not significant (p=0.276 and 0.305 respectively). The survival analysis shows a higher recurrence risk in the intervention group compared to the control group (HR 1.71), but it was not significant (p=0.231). The variation in the donors’ readiness to change was similar between the two groups (p=0.401). Conclusions: The present intervention showed a non-significant increase in the recurrence of voluntary blood donation. This study did not demonstrate a significant variation in the donors’ readiness to change.
