背景贫血在艾滋病患者中十分常见。在高效抗逆转录病毒治疗(HAART)的时代前,贫血与存活率降低有关。本研究调查了开展HAART后,贫血流行率及贫血治疗与存活率间的关系。研究设计和方法对一群HIV感染者作贫血流行率调查。在更小一些一群HIV贫血患者中,根据时间依赖危险渐进模型建立存活率模型,并用CD4+T淋巴细胞计数、血浆HIV Background Anemia is very common in people with AIDS. Anemia is associated with reduced survival before the era of highly effective antiretroviral therapy (HAART). This study investigated the prevalence of anemia and the relationship between anemia treatment and survival after HAART. Study design and methodology A population-based survey of anemia prevalence among HIV-infected individuals. In a smaller group of HIV anemia patients, a survival-time model was established based on a time-dependent, risk-progressive model and was evaluated by CD4 + T-lymphocyte count, plasma HIV
