von Willebrand disease (VWD) is a bleeding disorder that occurs in up to 1% of the general population. The great majority of females with VWD experience menorrhagia. The morbidity burden in females with VWD may relate to iron deficiency resulting from menorrhagia. To explore relationships between bleeding disorders, menorrhagia, iron deficiency and the outcomes of health-related quality of life (HRQL) and educational attainment. All subjects with VWD, and females with other bleeding disorders, in the Canadian national registry who were more than 12 years of age were eligible for survey. Survey measures included the HEALTH UTILITIES INDEX(®); abridged Clinical History Assessment Tool; socio-demographic questions and serum ferritin. Statistical analyses included testing differences among groups of means using analysis of variance and of proportions using chi-squared test. Significant size differences in mean HRQL scores were detected between VWD females and both females with other bleeding disorders [diff = (-0.08); P = 0.017] and VWD males [diff = (-0.07); P = 0.039]. Mean HRQL scores differed between females with and without menorrhagia (P < 0.001). Mean HRQL scores were not significantly different between females with and without iron deficiency. Educational attainment was not associated with disease group, menorrhagia status or iron status. Females with VWD have a greater morbidity burden than females in the general population, females with other bleeding disorders and males with VWD. Menorrhagia is associated with low HRQL scores in females with bleeding disorders, including VWD. Further investigation should assess how menorrhagia impacts HRQL in females with bleeding disorders.
血管性血友病(VWD)是一种出血性疾病,在普通人群中的发病率高达 1%。大多数患有 VWD 的女性都经历过月经过多。患有 VWD 的女性的发病率负担可能与月经过多导致的缺铁有关。为了探讨出血性疾病、月经过多、缺铁与健康相关生活质量(HRQL)和教育程度的结果之间的关系。加拿大国家登记处所有年龄超过 12 岁的 VWD 患者和其他出血性疾病的女性患者都有资格接受调查。调查措施包括健康效用指数(®);简化临床病史评估工具;社会人口统计学问题和血清铁蛋白。统计分析包括使用方差分析测试组间均值的差异,使用卡方检验测试组间比例的差异。VWD 女性与其他出血性疾病女性[差异=(-0.08);P=0.017]和 VWD 男性[差异=(-0.07);P=0.039]之间的平均 HRQL 评分存在显著差异。有和没有月经过多的女性之间的平均 HRQL 评分存在差异(P<0.001)。有和没有缺铁的女性之间的平均 HRQL 评分没有显著差异。教育程度与疾病组、月经过多状况或铁状况无关。VWD 女性的发病率负担大于普通人群中的女性、其他出血性疾病女性和 VWD 男性。月经过多与出血性疾病女性(包括 VWD)的低 HRQL 评分相关。进一步的研究应该评估月经过多如何影响出血性疾病女性的 HRQL。
