目的了解献血者参加无偿献血的原因,比较献血者影响圈和关注圈的献血行为对其参加无偿献血的影响,为无偿献血的招募、宣传工作提供科学参考。方法采用自行设计的问卷,对北京市城区的1 585名献血者进行问卷调查。结果 86.1%的献血者是通过身边的献血者了解无偿献血,其中11.2%的献血者能够参与无偿献血的主要原因是“身边有人参加了无偿献血”。献血者影响圈内朋友参加献血的最多,同时朋友献血对献血者参加献血影响也最大。献血者对影响圈献血行为的知晓情况与献血行为能够影响献血者参加献血之间有统计学意义(P<0.05)。51.4%的献血者认为明星献血对献血宣传有一定效果,但明星献血对献血者参加献血影响最小。结论影响圈比关注圈对献血者的献血行为影响更大。在今后的工作中,我们应该充分发挥影响圈和关注圈的作用,提高招募、宣传的效果,不断扩大无偿献血队伍。 Objective To understand the causes of blood donation to participate in voluntary blood donation, compare the influence of blood donation and donation circle of donors on their participation in unpaid blood donation, and provide scientific reference for recruitment and publicity of blood donation. Methods A questionnaire designed by ourselves was used to survey 1 585 blood donors in downtown Beijing. Results 86.1% of donors knew about blood donation through their blood donors. Among them, 11.2% of donors were able to participate in blood donation. The main reason is that “some people are involved in blood donation”. Blood donors affect the circle of friends to participate in blood donation up to the maximum, while friends blood donation blood donors to participate in blood donation most affected. There was a significant difference (P <0.05) between the number of donors who knew about blood donation behavior and the number of blood donors who could influence their blood donation. 51.4% of blood donors believe that star donation has some effect on blood donation, but star donors donate blood donors to participate in blood donation has the least impact. Conclusion The influence circle has more influence on the blood donation behavior than the circle of concern. In future work, we should give full play to the role of the circle of influence and the circle of attention, enhance the effect of recruitment and publicity, and continuously expand the blood donation team.
