Sociodemographic and Way of life Determinants of HIF-1α Response to Blood Donation and Hematopoietic Components: Epidemiological and Public Well being Views from Voluntary Donors

Background/Objectives: Blood donation is important to well being programs and represents a priceless epidemiological mannequin for finding out physiological adaptation to managed blood loss. Regular blood donors represent a definite, health-screened inhabitants whose organic responses supply distinctive perception into mechanisms of resilience and key determinants of inhabitants well being. Hypoxia-inducible issue 1-alpha (HIF-1α) is a key regulator of erythropoiesis and mobile response to hypoxia, and its modulation following blood donation could inform donor security and the sustainability of blood donation packages. This examine aimed to characterize the sociodemographic, life-style, and anthropometric profiles of blood donors in relation to hematopoietic biomarkers (vitamin B12 and folic acid) and to judge adjustments in serum HIF-1α focus after donation, emphasizing the general public well being relevance of voluntary blood donation. Methods: A cross-sectional examine was carried out amongst 324 voluntary blood donors (159 common and 165 occasional). Serum HIF-1α was measured earlier than and 30 min after donation, along with vitamin B12 and folic acid ranges. Sociodemographic and life-style traits (bodily exercise, smoking, dietary habits) had been collected via standardized questionnaires (EHIS-3, FFQ), and anthropometric parameters had been assessed. Results: Regular donors had been older and predominantly male, with comparable socioeconomic indicators between teams. Both common and occasional donors confirmed favorable life-style profiles, together with low smoking prevalence and average bodily exercise. Skinfold thickness was considerably larger in common donors (p < 0.001). The fundamental organic discovering was a strong post-donation improve in HIF-1α concentrations (≈80%, p < 0.001), impartial of donation frequency or life-style. No vital associations had been discovered between life-style components and vitamin B12 or folate ranges. Conclusions: Blood donation induces a fast elevation in HIF-1α, reflecting activation of hypoxia-responsive pathways and short-term hematopoietic adaptation. Beyond its biomedical relevance, voluntary blood donation represents a significant epidemiological and public well being mannequin for finding out physiological resilience and the well being advantages of altruistic habits. These findings underscore the significance of donor surveillance and motivation as parts of broader preventive well being and well being fairness methods.
