ABSTRACT
【Objective】 To explore the promote and deter factors of blood donation among street blood donors in Nanjing, in order to improve the accuracy of street blood donors recruitment. 【Methods】 A questionnaire with high confidence was designed based on the theory of planned behavior(TPB). The multi-stage hierarchical sampling method was adopted according to the geographical location and economic development level of 11 districts(regions) in Nanjing, and the street blood donors were divided into three groups according to the history of blood donation: one donation(n=361), donation numbers ≥ 2(n=417)and non-donation (n=241). The blood donation behavior was investigated from four aspects as external promote factors (such as seeking a free blood examination, self-interest factors, etc.), internal promote factors(such as altruistic, self-interest factors, blood donation can help others, etc.), external deter factors (too busy to donate blood, opposition from my family, etc.) and internal deter actors ( worry about dizziness after blood donation, fear of needles, ect.). The database was established using Epidata software, and chi-square test was applied for statistical analysis between groups. 【Results】 The groups mainly affected by the promote factors (altruistic and self-interest factors) of Nanjing street population in blood donation were unmarried, 18~24 years old, childless, below bachelor degree, and have barely no income. The main groups less affected by the deter factors were students, male, unmarried, 18~24 years old, childless and have barely no income.Promote factors increases with the number of blood donations, while deter factors decreases with the number of blood donation. 【Conclusion】 TBP can better analyze and explain the promote and deter factors affecting blood donation behavior among street blood donors in Nanjing, which is helpful for blood stations to formulate targeted measures to improve the availability of street blood donors.
