Mediating Effect of Unpaid Blood Donation Cognition between Unpaid Blood Donation and Health
摘要
Abstract
Objective To test the mediating effect of unpaid blood donation cognition between unpaid blood donation and health.Methods Field and online questionnaire surveys were used in this study.The participants were unpaid blood donors and some of their companions without donating blood.The field questionnaire survey was carried out in Beijing Red Cross Blood Center′s blood collecting sheds and vehicles,and online questionnaire survey was implemented on professional survey websites from May to September 2016.Printed and electronic Unpaid Blood Donation Cognition Questionnaire and Chinese version of 36-item Short Form Heath Survey Questionnaire (SF-36) were respectively used in the field and online survey for assessing the unpaid blood donation cognition and status of health.Times of unpaid blood donation was used to group the participants.Hierarchical linear regression was adopted to explore the mediating effect of unpaid blood donation cognition between unpaid blood donation and health.Results A total of 1 093 participants received the surveys,94.33% of them (1 031/1 093) returning responsive questionnaires were selected as the final participants.Fifteen point zero four percent(155/1 031) of them had not donated blood,39.96%(412/1 031) had donated blood unpaidly 1-4 times,21.82%(225/1 031) had done that 5-9 times,and 23.18%(239/1 031) had done that ≥10 times.Among the participants,unpaid blood donation cognition,PCS and MCS scores differed significantly among those who had donated blood unpaidly(P<0.001);participants who had donated blood unpaidly had higher unpaid blood donation cognition,PCS and MCS scores than those who had not;participants who had donated blood unpaidly 5 times or over had higher unpaid blood donation cognition,PCS and MCS scores than those who had done that 1-4 times;participants who had donated blood unpaidly ≥10 times had higher unpaid blood donation cognition scores than those who had done that 5-9 times(P<0.05).Unpaid blood donation was positively correlated with PCS(rs=0.285,P<0.05),MCS(rs=0.288,P<0.05) and unpaid blood donation cognition(rs=0.344,P<0.05).Unpaid blood donation cognition was positively associated with PCS(r=0.233,P<0.05) and MCS(r=0.253,P<0.05).Unpaid blood donation cognition played the role as an intermediary in part between unpaid blood donation and PCS,and between unpaid blood donation and MCS,accounting for 23.78% and 32.43% of the total mediating effect,respectively.Conclusion Unpaid blood donation cognition exerts partial mediating effect between unpaid blood donation and health,accounting for about 1/3 of the total effect.关键词
