“…In our study, prior blood donation prevalence was lower than the 30% prevalence observed in other Brazilian studies among the general population in Florianópolis (Silva, Kupek, & Peres, 2013), Pelotas (Zago, Silveira, & Dumith, 2010), and Belo Horizonte (Moreno et al, 2016). We also found a higher prevalence of study participants who self-reported as being unable to donate blood; nearly 13% of the study participants compared to 3% among blood donor population in Belo Horizonte (Moreno et al, 2016). These discrepant results may be related to the source of study participants.…”

“…In our study, blood donation was more frequent among males and higher socioeconomic and educational level, in line with other studies (Moreno et al, ; Silva et al, ; Zago et al, ). The association of blood donation and gender has already been described (Bilal et al, ; Gonçalez et al, ; Moreno et al, ). Lower rates of female donors were expected as on the global population, only 30% of blood donation is from females and, in some countries this rate is even lower, reaching only 10% (Bani & Giussani, ).…”

“…Studies on blood donor profiles in the Brazilian populations (Carneiro‐Proietti et al, ; Goncalez et al, ; Gonçalez et al, ) indicate that individuals more likely to donate blood tend to be male, younger age group, with high economic and educational level (Carneiro‐Proietti et al, ; Gonçalez et al, ; Moreno et al, ; Zago et al, ). In our study, blood donation was more frequent among males and higher socioeconomic and educational level, in line with other studies (Moreno et al, ; Silva et al, ; Zago et al, ). The association of blood donation and gender has already been described (Bilal et al, ; Gonçalez et al, ; Moreno et al, ).…”

Population-based studies on blood donation prevalence and its association with sociodemographic and behavioural factors are scarce, but remain the best approach to assess correlates of donation, including those which could be the target for donor recruitment campaigns. This study describes the population of primary healthcare users from the public system in a medium-sized Brazilian municipality to investigate the association of blood donation practice with other sociodemographic factors. A stratified, representative sample of primary healthcare users at 12 healthcare facilities in Ribeirão Preto, São Paulo, Brazil, were invited to participate. Analysis focused on demographic and psychosocial factors including, sex, age, marital status, socioeconomic status, educational level, health insurance, self-perception of health, religious beliefs, and blood donation history. Blood donors, self-defined ineligible donors, and never donors were compared. Multiple correspondence analysis (MCA) was used to assess positively and negatively associated variables in the dataset. MCA was conducted on respondents' age and monthly household income to assess dimensionality of other questionnaire responses. Of a total of 1,055 study participants, 79.7% were females and the mean age was 40.6 years. Blood donation practice was reported by 246 participants (23.3%), 669 (63.4%) had never donated, and 140 (13.3%) reported being unable to donate blood. Graphical presentation of the MCA showed that male, older age groups, those who have health insurance, and with higher socioeconomic and educational level are more likely to donate blood. Poor or average self-perception of health, lower socioeconomic status, and divorced or widowed marital status were associated with self-defined inability to donate blood. Thus, our results are useful to understand the multifactorial nature of blood donation behaviour. Our findings provide guidance for targeted recruitment campaigns focused on relevant contextual factors. The focus on reducing barriers to blood donation according to sociodemographic groups can be a relevant strategy to expand the donor base.

“…Blood banks around the world are struggling with a permanent deficit of blood and despite the efforts to understand the psychosocial factors associated with blood donation, little is known about the reasons for non‐donation and the impact of different barriers on blood donating behaviours in distinct populations . Recruiting and retaining safe blood donors are especially challenging in developing countries . In 2012, the whole blood donation rate for the country was 18·75 donations per 1000 inhabitants .…”

Fear of blood, injections and fainting as barriers to blood donation in Brazil

Background and objectives The objective of the present study was to investigate the fear of blood, injections and fainting as barriers to blood donation in a sample of primary healthcare users in a Brazilian municipality. Materials and Methods This is a cross‐sectional survey of primary care patients in 12 randomly selected healthcare facilities in Ribeirão Preto, Brazil in 2015–2016. Key variables were lifetime blood donation history, intentions to donate blood among non‐donors and current donation practice. To assess fear of blood in general (FBG), fear of injections in general (FIG) and fear of fainting due to fear of injection (FFI), we used the Blood Injection/Fear Scale (BIFS). We tested associations between variables using regression models and conditional inference trees (CIT). Results A total of 1055 primary healthcare users participated (79·7% female, mean age 40·6 years [SD = 15·2]), 63·4% never donated blood, 13·3% reported they are unable to donate, 6·1% donated only once, 17·2% donated multiple times. Women had higher scores for FIG and FBG. FFI was associated with middle socioeconomic status. Those who never intended to donate exhibited the highest scores in the three dimension of fear. By CIT analysis, being female and high scores for FBG are associated with decreased blood donation. Among males, blood donation frequency is low among those aged 33 years and under. Conclusion Fear of blood, injections and fainting are barriers to blood donation in Brazil. Efforts to recruit and retain blood donors should convey information on blood donation processes and address misconceptions that may increase fear.

“…There was a considerable interest in Brazil for studying blood donor motivations, deterrents to donate and identifying population segments to be specifically targeted to improve blood donation (Zago et al, ; Gonçalez et al, ; Oliveira et al, ; Zangiacomi Martinez et al, ; Conceição et al, ; Moreno et al, ). This was well addressed by two studies from the same group supported by the US REDS programmes (Zago et al, ; Conceição et al, ).…”

SUMMARY Background Low‐ and middle‐income countries (LMIC) suffer from chronic or seasonal blood shortage. The first review was published in 2007. Methods The review of literature since 2005 presented here uncovered a fairly large number of articles justifying the grouping of blood donation issues into five geographical areas sharing common background. These are Sub‐Saharan Africa (SSA), Muslim countries, India, China/South East Asia and Latin America/Caribbean islands (LA&C). Results SSA countries start collecting at 16–18 years of age in schools where female donors can be reached better than in other settings. Community‐oriented culture favours family donors who need, similar to volunteer non‐remunerated donors (VNRD), to be actively induced to repeat donation. Muslim countries share the contradiction of religion encouraging blood donation but restrain women from donating. The active involvement of religious leaders and the progressive easing of female participation are the keys to increasing blood donation. In India, ‘social duty’ is a major inducement to blood donation but also benefits and rewards. Ways of involving female donors by reducing the donation age to 16 years and providing donor education in schools need to be considered. In China and East Asia, the option of small‐volume donation impairs blood collection without being justified by scientific evidence but is a concession to culture. Reducing the donation age would also help the supply. In LA&C, the concept of ‘social capital’ was developed as a complement or alternative to the theory of planned behaviour. Conclusions Strategies to improve blood donation and repeat donation should be innovative and adapted to local or regional culture and environment.
