Abstract ObjectiveTo explore the influencing factors of repeat blood donation behavior among voluntary nonremunerated blood donors and provide evidence for promoting repeated blood donation.MethodsA follw一up survey was conducted from January 202l to June 2022.Baseline surveys and one-year folow一ups were carried out among 5 535 voluntary non-remunerated blood donors of legal donation age across 31 provinces （autonomous regions，municipalities directly under the central government） in China. Results：Among the participants， 19.1% of first-time donors donated blood again，while the proportion was 33.0% for repeat donors and reached 62.2% for regular donors. The mean blood donation intentionscoreofregular donors was 4.68，which was higher than thatof repeat donors （4.29）and first—time donors（4.16）（ P<0.001 ）. As the number of blood donations increased， the personal norm score rose from 4.15 for first-time donors to4.48 forregular donors，andtheperceivedbehavioral control score increased from4.25 for first—time donors to 4.66 for regular donors （ P<0.001 ）.However， the influence of subjective norms on blood donation behavior graduall decreased.Logistic regresionanalysis revealed that young age，male gender，being ateacher， donor type，and positive donation intention were significantfactors influencing repeat blood donation behavior.After excluding thedonation intentionvariable，behavioralatitude，personalnorm，andperceived behavioralcontrolhad positive effects on repeat blood donation behavior （ P<0.05 ）.Conclusion The probability of repeat blood donation among donors increases with the number of previous donations，and blood donation behavior exhibits a dynamic development process of "external drive $$ experience enhancement $$ internalized identification". Blood donation recruitment and incentive measures should be precisely implemented according tothe behavioral characteristics of donors at diferent stages to promote repeated blood donation and ensure a stable blood supply.
