献血场景差异对西安献血人群及血液质量的影响研究OA

Objective To explore the impact of different blood donation scenarios on population characteristics and blood donation behaviors,and to provide a basis for precise blood donation recruitment.Methods Eligible voluntary blood donors with complete records from four scenarios in Xi'an:medical institutions,cultural tourism SITES,commercial super-stores,and blood centers.After a preliminary analysis of overall donor characteristics across the four scenarios,three core subgroups were defined based on scenarios and donor population differences:the medical subgroup(aged 30-39 years),the blood center subgroup(aged 30-39 years),and the cultural tourism and commercial superstore subgroup(aged 18-29 years).Baseline characteristics,blood donation behaviors,and blood test results were compared among the subgroups.Re-sults The blood donors in all four scenarios were mainly male,but the proportion of female donors in the medical scenario was the highest(26.4%,8 878/33 634).In terms of age distribution,the cultural tourism and commercial superstore sce-narios were dominated by donors aged 18-29,while the blood center and medical scenarios were dominated by those aged 30-39,with the highest proportion of donors over 40 in the medical scenario.The occupational and educational composition of blood donors in the blood center scenario spanned a wide range,exhibiting a clear bipolar distribution.Significant differ-ences were observed in baseline characteristics,blood donation behaviors,and blood test results among the three core sub-groups(P＜0.001).The medical subgroup was mainly composed of enterprise/industrial workers and married individuals,with high proportions of first-time blood donors,and the highest unqualified rate of infectious indicators(2.0%,274/13 509).The cultural tourism and commercial superstore subgroup was mainly unmarried and students,featured high pro-portions of large-volume donations and evening donations,and had a relatively high unqualified rate for ALT(0.4%,130/31 443).The blood center subgroup had a complex population structure,a high proportion of repeat blood donors(45.3%,6449/14 225),and moderate results in all test indicators.Conclusion There is an inherent correlation between the attrib-utes of blood donation scenarios,population characteristics,and blood donation behaviors.The differences among the three core subgroups provide a clear basis for precise scenario operation.By constructing transformation channels between different scenarios and optimizing scenario-specific strategies,the structure of blood donors can be improved,thereby supporting the sustainable development of voluntary blood donation.
