Past Donor Eligibility: Dietary and Life-style Heterogeneity and Implications for Lengthy-Time period Donor Well being Preservation

Abstract

Background: Blood donor eligibility is important for donation security, however it might not totally seize dietary, metabolic, and lifestyle-related vulnerabilities that may have an effect on donor well being over time. As transfusion programs more and more depend on common donors, figuring out modifiable elements that will assist long-term donor well being and retention is changing into more and more related. This examine aimed to characterize dietary and way of life heterogeneity, peri-donation dietary behaviors, and donation-related outcomes in grownup blood donors. Methods: This cross-sectional survey used a structured on-line questionnaire assessing anthropometric traits, way of life elements, routine dietary consumption, nutrition-related consciousness, peri-donation dietary behaviors, self-reported historical past of iron deficiency, and post-donation signs. Dietary profiles have been recognized utilizing principal part evaluation adopted by k-means clustering. Multivariable logistic regression fashions have been used to discover elements related to iron deficiency historical past and post-donation signs. Results: The examine included 698 grownup blood donors. Overweight and weight problems affected practically half of the cohort and have been extra frequent amongst males and older donors, whereas ladies extra incessantly reported iron deficiency historical past and post-donation signs. Three dietary profiles have been recognized: Western/ultra-processed, Mediterranean-like, and combined beverage-oriented. Younger donors have been extra incessantly represented in much less favorable dietary and way of life profiles, whereas older donors confirmed extra favorable dietary habits regardless of the next prevalence of obese/weight problems. In multivariable analyses, feminine intercourse was independently related to iron deficiency historical past (OR 4.62, 95% CI 3.20–6.68; p < 0.001) and post-donation signs (OR 3.07, 95% CI 2.09–4.52; p < 0.001), whereas growing age was inversely related to post-donation signs (OR 0.73 per 10-year improve, 95% CI 0.64–0.84; p < 0.001). Dietary sample membership was not independently related to both final result. Peri-donation dietary modifications have been reported extra incessantly earlier than donation than after donation. Discussion: These findings recommend that grownup blood donors symbolize a nutritionally and metabolically heterogeneous inhabitants regardless of donation eligibility. These findings assist the potential relevance of structured dietary counseling, lifestyle-oriented prevention, and recovery-focused suggestions inside donor care pathways, though their influence on long-term donor well being, continued eligibility, and donor retention ought to be evaluated in future potential and interventional research.
