The prototypical UK blood donor, homophily and blood donation: Blood donors are like you, not me

Abstract

AbstractBackground and ObjectivesHomophily represents the extent to which people feel others are like them and encourages the uptake of activities they feel people like them do. Currently, there are no data on blood donor homophily with respect to (i) people's representation of the average prototypical UK blood donor and (ii) the degree of homophily with this prototype for current donors, non‐donors, groups blood services wish to encourage (ethnic minorities), those who are now eligible following policy changes (e.g., men‐who‐have‐sex‐with‐men: MSM) and recipients. We aim to fill these gaps in knowledge.Materials and MethodsWe surveyed the UK general population MSM, long‐term blood recipients, current donors, non‐donors and ethnic minorities (n = 785) to assess perceptions of the prototypical donor in terms of ethnicity, age, gender, social class, educational level and political ideology. Homophily was indexed with respect to age, gender and ethnicity.ResultsThe prototypical UK blood donor is perceived as White, middle‐aged, middle‐class, college‐level educated and left‐wing. Current donors and MSM are more homophilous with this prototype, whereas recipients and ethnic minorities have the lowest homophily. Higher levels of homophily are associated with an increased likelihood of committing to donate.ConclusionThe prototype of the UK donor defined this as a White activity. This, in part, may explain why ethnic minorities are less likely to be donors. As well as traditional recruitment strategies, blood services need to consider broader structural changes such as the ethnic diversity of staff and co‐designing donor spaces with local communities.
