Demographic profile of blood donors at three major Brazilian blood centers: results from the International REDS‐II study, 2007 to 2008

Abstract

BACKGROUND-The profile of blood donors changed dramatically in Brazil over the past 20 years, from remunerated to non-remunerated and then from replacement to community donors. Donor demographic data from three major blood centers establish current donation profiles in Brazil, serving as baseline for future analyses and tracking longitudinal changes in donor characteristics.

Prevalência de doação de sangue e fatores associados em Florianópolis, Sul do Brasil: estudo de base populacional

“…Além disto, naquele estudo, a prevalência de infecção pelo HIV não esteve associada com a motivação para doação (espontânea ou reposição) entre doadores de repetição 5 . Estimativas em centros de coleta de diversas regiões do país sugerem que a contribuição das doações para reposição varia entre 19% a 52% 3,23 . Em nosso estudo, a proporção de participantes que referiram doação para reposição foi menor do que naqueles centros.…”

“…Em Florianópolis, a distribuição por faixa etária dos doadores que manifestaram doação nos últimos 12 meses foi diferente do restante do país, onde é estimado que a maioria dos doadores de sangue apresentem idade superior a 29 anos 3,7,23 . Os motivos pelos quais os doadores em Florianópolis são mais jovens não estão claros.…”

Human T-Lymphotropic Virus Type 1 and Type 2 Seroprevalence, Incidence, and Residual Transfusion Risk Among Blood Donors in Brazil During 2007–2009

“…Data from metropolitan areas of Europe suggest that the seroprevalence of HTLV-1 in pregnant women may be up to 100 times higher than in blood donors. 22 Since blood donors come from a relatively healthier stratum of the population, and in the studied centers tend to be younger and males, 18 we estimate that the HTLV prevalence in the general population of the Brazilian States where the study was conducted is several times higher, and therefore worthy of public health surveillance. This ''sentinel'' aspect of the blood banking activity should be emphasized: the reasons for deferring blood donors may point to local health problems and be a ''thermometer'' of adult population well being.…”

“…The participating centers were Fundaçã o Pró -Sangue (FPS) in Sã o Paulo State (Southeast region), Hemominas, in Minas Gerais State (Southeast region), and Hemope in Pernambuco State (Northeast region), as previously described. 18 We calculated prevalence in first time blood donors (those who had never donated previously in each center) and incidence among all repeat donors whose previous donation in the blood center was negative. Donor characteristics were recorded at the time of donation; according to common practice in Brazil, skin color was recorded instead of race and ethnicity, and was self-reported.…”

Marketing social para doação de sangue: análise da predisposição de novos doadores

“…Já na década de 1990, as organizações públicas desenvolveram programas de recrutamento de doadores entre os familiares e amigos dos indivíduos hospitalizados, os chamados doadores de reposição 8 .…”
