背景：人口老龄化将影响医疗保健的提供，特别是因为额外的岁月不一定会保持良好的健康状况。识别和理解老年人常见医疗问题的重要性非常重要。贫血可能就是这样的问题之一。我们报告了一般人群中老年人群贫血的患病率。贫血的存在与发病率和死亡率的预后较差有关。 方法：使用电子搜索和已发表报告的参考列表来识别报告了至少 100 名主要生活在发达国家的 65 岁及以上个体的队列中贫血患病率的研究，以及用于定义贫血的标准。特定疾病组贫血患病率的研究或 1980 年之前发表的研究被排除在外。提取了整个队列、男性和女性以及不同年龄段的患病率数据。 结果：45 项研究提供了数据。 34 项研究 (n = 85,409) 使用 WHO 标准来定义贫血。总体加权平均患病率为 17% (3-50%)，社区研究中为 12% (3-25%) (27, n = 69,975)，疗养院研究中为 47% (31-50%) (3, n = 1481)，入院研究中为 40% (40-72%) (4, n = 13,953)。贫血患病率随着年龄的增长而增加，男性略高于女性，黑人高于白人。根据世界卫生组织的标准，大多数被归类为贫血的人只是轻度贫血。结论：根据世界卫生组织的标准，贫血在社区老年人中很常见，尤其是在疗养院居民和住院患者中。预测的人口变化强调需要更多地了解老年人贫血。
BACKGROUND: Ageing populations will impact on healthcare provision, especially since extra years are not necessarily spent in good health. It is important to identify and understand the significance of common medical problems in older people. Anaemia may be one such problem. We report on the prevalence of anaemia in cohorts of elderly people in the general population. The presence of anaemia is associated with a worse prognosis for both morbidity and mortality.METHODS: Electronic searching and reference lists of published reports were used to identify studies that reported on prevalence of anaemia in cohorts of at least 100 individuals predominantly aged 65 years and over living in developed countries, together with criteria used to define anaemia. Studies of anaemia prevalence in specific disease groups or published before 1980 were excluded. Prevalence data for the entire cohort, for men and women separately and for different age bands were extracted.RESULTS: Forty-five studies contributed data. Thirty-four studies (n = 85,409) used WHO criteria to define anaemia. The weighted mean prevalence was 17% (3-50%) overall, and 12% (3-25%) in studies based in the community (27, n = 69,975), 47% (31-50%) in nursing homes (3, n = 1481), and 40% (40-72%) in hospital admissions (4, n = 13,953). Anaemia prevalence increased with age, was slightly higher in men than women, and was higher in black people than white. Most individuals classified as anaemic using WHO criteria were only mildly anaemic.CONCLUSION: Anaemia, as defined by WHO criteria, is common in older people living in the community and particularly common in nursing home residents and hospital admissions. Predicted demographic changes underline the need to understand more about anaemia in older people.
