Analysis on blood donation of college student groups in Tianjin, 2012-2021
Abstract
Objective To investigate the basic situation of blood donation given by university students in Tianjin and provide data to support the sustainable development of college blood donation. Methods The group blood donation in Tianjin universities from 2012 to 2021 was enrolled as the study group and other whole blood donors in the same period as the control. The statistical analysis of the two groups was conducted. Results From 2012 to 2021, the number of college blood donations in Tianjin increased from 8.93% to 21.32%, with the average annual growth rate of 12.80%, and the units of blood donated increased from 5.44% to 18.82%, with the average annual growth rate of 17.06%. The repeat donation rate in the study group was significantly lower than that of the control(20.74% vs 25.47%, P<0.05). In 2012, the specification of blood donated by college students were mainly 200 mL(87.38%), then in 2021, gradually transitioned to 400 mL(38.77%), followed by 200 mL(35.19%) and 300 mL(26.03%). The rates of 200/300 mL donation and insufficient blood donation in the study group were significantly higher than those in the control, to the contrary, the rate of 400 mL donation was lower in comparison to the control, with statistically significant differences. The deferral rates of initial screening and ALT among college donors differed significantly over the decade: HBsAg showed a significant downward trend, while Hb increased significantly(P<0.05); the deferral items in the study group was significantly lower than the control(P<0.05), except Hb. During the retest period, the deferral rates of ALT and HBV were decreasing, which was the lowest in 2018 then bounced back slightly; the deferral rate of HIV showed a increasing tendency(P<0.05). The deferral rates of all retest items in the study group were lower than those in the control(P<0.05). In the study group, no significant differences were noticed in the deferral rates of retest items by genders, except for ALT and HCV, as males were higher than females. Conclusion College student groups are an important force in blood donation. A long-term mechanism should be established to safeguard this special group and to provide targeted health education and personalised services to promote the sustainable and healthy development of blood donation in universities.
