Promoting awareness of donation-related iron depletion among high risk blood donors

Background The potential for iron deficiency is a known blood donor health concern and suggests the need to inform donors about the potential risks of low iron levels as well as strategies to address these risks. Study design and methods Frequent (n = 904) and young (n = 629) donors were randomly assigned within risk group to either a control (n = 548) or an intervention (n = 985) group. The control group answered questions at baseline and 6-month follow-up regarding their awareness of the risk of donation-related iron depletion and whether they were taking actions to address their iron status. The intervention group answered the same questions at baseline and follow-up, but after completing the baseline survey, they received information regarding their risk of iron depletion and behaviors they could adopt to mitigate this risk. Intervention group participants were also offered the opportunity to develop an action plan to help them supplement their iron intake. Results The intervention enhanced overall awareness of donation-related iron loss (OR = 1.5, 95% CI 1.171-1.864, p = .001), with no negative impact on retention. Reported iron health behaviors (iron supplementation, speaking with a doctor) showed significant increases when action planning was paired with the educational information. Conclusion These findings suggest that it is possible to increase awareness of donation-related risk for iron depletion without negatively influencing retention, and combining education with encouragement to develop an action plan may increase the likelihood of both retention and behavioral changes to promote healthy iron levels.
