To identify factors that influence refusing to donating blood.
Prospective case and control study. Hospitalized patients' relatives were interviewed with a questionnaire to evaluate their knowledge of blood and personal attitudes toward blood donation. Cases were all relatives who did not donate blood and controls who did.
A total of 121 individuals was studied, 30 cases and 91 controls. Age of the cases was 32.3 +/- 8.1 years and controls was 28.8 +/- 7.9 years (p = 0.04). Risk factors were female sex (OR = 6.3; 95%CI 2.4 to 17.1), being married (OR = 3.7 95%CI 1.3 to 10.5). No differences were present between the two groups in level of knowledge concerning blood. The average of positive attitudes toward blood donation was greater among relatives who donated blood (cases 5.9 +/- 1.6; controls 6.4 +/- 1.2; P = 0.049). Among the attitudes that influence refusing to donate blood were fear of getting dizzy at the sight of blood (OR = 5.2, 95%CI 1.3-21.4), fear of donating blood (OR = 2.2, 95%C, 0.8-6.0), and getting nervous at the sight of blood (OR = 4.1, 95%CI% 1.5-10.9).
Among patient's relatives who donate blood positive personal attitudes toward blood donation have more weight than knowledge on the subject.
确定影响拒绝献血的因素。
前瞻性病例对照研究。采用问卷调查法对住院患者的亲属进行访谈，以评估他们对血液的了解程度和个人对献血的态度。病例组为所有未献血的亲属，对照组为献血的亲属。
共研究了121人，其中30例病例和91例对照。病例组年龄为32.3±8.1岁，对照组为28.8±7.9岁（p = 0.04）。危险因素为女性（OR = 6.3；95%CI 2.4至17.1）、已婚（OR = 3.7，95%CI 1.3至10.5）。两组在血液知识水平方面无差异。献血亲属对献血的积极态度平均值更高（病例组5.9±1.6；对照组6.4±1.2；P = 0.049）。影响拒绝献血的态度包括看到血会头晕的恐惧（OR = 5.2，95%CI 1.3 - 21.4）、害怕献血（OR = 2.2，95%CI 0.8 - 6.0）以及看到血会紧张（OR = 4.1，95%CI 1.5 - 10.9）。
在献血的患者亲属中，对献血的积极个人态度比该主题的知识更重要。
