ObjectivesThis study aimed to (1) determine the knowledge level of young adults towards blood donation, and (2) to understand their donor identity and the meanings of blood donation to them.DesignA questionnaire-based cross-sectional survey.Setting and participantsUndergraduate students of a university in Hong Kong recruited by convenience sampling, at public facilities in campus such as student canteens and the Campus Blood Donor Centre of the university.Outcome measuresThe questionnaire which consisted of three parts was used for data collection. Part 1 collected sociodemographic information and items associated with blood donation; part 2 related to knowledge on blood donation and part 3 focused on blood donor identity. Univariate and multivariate logistic regression analyses were conducted to determine the OR and identify the predictors for blood donation.ResultsAmong the 542 respondents, 274 were non-blood donors and 268 were blood donors. Blood donors generally have a better knowledge towards blood donation than non-blood donors. The results of univariate analyses indicated that being a female (OR=1.99, p<0.001), aged 22 years or above (OR=234, p<0.001), studying at year 4 or 5 (OR=2.12, p=0.003), studying health-related programmes (OR=1.96, p<0.001), being registered as an organ donor (OR=6.59, p<0.001), had prior experience of receiving blood (OR=7.60, p<0.001) or prior experience of being refused for blood donation (OR=5.14, p<0.001) were significantly associated with being a blood donor. Having prior experience of receiving blood was the strongest predictor for being a blood donor, followed by being registered as an organ donor, after controlling for all other factors in the logistic regression model.ConclusionsThe findings are consistent with self-determination theory, which hypothesises that people are more likely to abide with blood donation behaviours that are internally rather than externally motivated.

“…The BDQK-Brazil is an original instrument that aims to measure and validate general blood donation knowledge among primary healthcare users. 9 The results of this study show that the instrument is comprised of easy-to-understand questions with an adequate discrimination capability, which suggests that it can be used in many settings, including for donors and non-donors, and in different social and educational levels. Higher mean numbers of correct answers were associated with being female, having a higher educational level and previously donating blood.…”

“…In addition to the low number of studies with large representative samples, there is no specific instrument to ascertain this knowledge considering the specificities of blood donation in Brazil. Thus, our research group developed a 24-item scale named the Blood Donation Knowledge Questionnaire (BDKQ-Brazil) 9 based on an instrument proposed by Renzaho and Polonsky. 10 BDKQ-Brazil includes questions based on some popular beliefs and notions common to the Brazilian population.…”

BackgroundTo present the results of the application of the Blood Donation Knowledge Questionnaire in a large and representative sample of users of primary care services in order to extend the evaluation of the metrics of the items and to assess knowledge about blood donation in association with sociodemographic variables.MethodThe Blood Donation Knowledge Questionnaire is composed of 24 items based on blood donation requirements of the Brazilian Ministry of Health and on some popular beliefs and concepts of the Brazilian population regarding the blood donation process. Data collection was carried out in 12 healthcare facilities of Ribeirão Preto, São Paulo. The analysis of items was performed using classical test theory with associations being assessed using the multivariate Tobit regression model.ResultsA total of 1055 individuals participated (79.7% females and a mean age of 40.6 years). Previous blood donation was reported by 246 (23.3%) participants, 669 (63.4%) had never donated, and 140 (13.3%) reported being ineligible to donate blood. This questionnaire is comprised of items considered easy-to-understand, with a facility level of medium to high and generally an adequate capability of discrimination. Higher means of correct answers were detected among females, individuals with more schooling, and subjects who had already donated blood.ConclusionThe Blood Donation Knowledge Questionnaire is an instrument that aims to measure some general aspects of knowledge regarding blood donation and can be used in different contexts. There is evidence that knowledge of primary healthcare users regarding blood donation is correlated to sex, educational level, and previous blood donation.

“…In order to evaluate this new concept in the transfusion area, three main measures were examined: altruism, self‐interest and response to appeal. In the population of four major Brazilian blood centres, 73% were young (18–39 years of age), educated (71% high school and higher), 50% married or with partners and 37·4% expressed high level of cognitive SC and 19% of structural SC (Lucindo Zocoloto & Zangiacomi Martinez, ). Altruism was expressed by 43·5% and response to direct appeal (being asked) by 42% of respondents but only 27% for self‐interest.…”

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.
