RESUMEN
ABSTRACT Background: Test-seeking is associated with HIV in Brazilian blood donors. This study sought to investigate the frequency with which three different donor groups: deferred donors, accepted donors who tested HIV positive [HIV (+)], and accepted donors who tested infectious disease markers negative [IDM (−)], came to the blood bank at the suggestion of a health care professional. Study design and methods: Donors deferred for reporting high-risk behaviors and participants in an HIV risk factor case-control study completed a confidential audio computer-assisted self-interview (ACASI) that included two questions related to health care professionals and test-seeking. Results: Of 4013 enrolled deferred donors, 468 (11.8%) reported a health care professional suggested donation as a way to be tested for infection. Of 341 HIV (+) and 791 IDM (−) participants, 43 (12.6%) and 11 (1.4%), respectively, reported a health care professional suggested donation as a way to be tested for infection. Physicians were the most frequently reported source of referral: [(61.5% of deferred, 69.1% of HIV (+), and 9.1% of IDM (−) donors)]. Conclusion: HIV (+) donors and deferred donors were 10 times more likely to report test-seeking behavior by suggestion of health care professional than IDM (−) donors. If true, efforts should be made to educate health care professionals and blood donors on how to safeguard the blood supply, emphasizing that HIV testing should be done at volunteer testing centers rather than at the blood centers.

RESUMEN
BACKGROUND: Studies analyzing motivation factors that lead to blood donation have found altruism to be the primary motivation factor; however, social capital has not been analyzed in this context. Our study examines the association between motivation factors (altruism, self-interest, and response to direct appeal) and social capital (cognitive and structural) across three large blood centers in Brazil. STUDY DESIGN AND METHODS: We conducted a cross-sectional survey of 7635 donor candidates from October 15 through November 20, 2009. Participants completed self-administered questionnaires on demographics, previous blood donation, human immunodeficiency virus testing and knowledge, social capital, and donor motivations. Enrollment was determined before the donor screening process. RESULTS: Among participants, 43.5 and 41.7% expressed high levels of altruism and response to direct appeal, respectively, while only 26.9% expressed high levels of self-interest. More high self-interest was observed at Hemope-Recife (41.7%). Of participants, 37.4% expressed high levels of cognitive social capital while 19.2% expressed high levels of structural social capital. More high cognitive and structural social capital was observed at Hemope-Recife (47.3 and 21.3%, respectively). High cognitive social capital was associated with high levels of altruism, self-interest, and response to direct appeal. Philanthropic and high social altruism were associated with high levels of altruism and response to direct appeal. CONCLUSION: Cognitive and structural social capital and social altruism are associated with altruism and response to direct appeal, while only cognitive social capital is associated with self-interest. Designing marketing campaigns with these aspects in mind may help blood banks attract potential blood donors more efficiently.
