背景：日本是世界上老龄化人口最多的国家，因此，在临床老年医学实践中，关注虚弱是很重要的。使用全国代表性的样本，这项研究提供了社区居住的日本老年人之间的脆弱的流行率的全国估计。我们还研究了社会人口学特征、健康状况和地理区域的患病率变化。方法：数据来自2012年日本全国老年人调查。这些数据是通过家庭访问和与训练有素的访谈人员进行面对面访谈收集的。样本包括2206名年龄≥ 65岁的成年人。结果：总体估计患病率为8.7%（7.5%-9.9%），虚弱前期为40.8%（38.7%-42.9%），健壮为50.5%（48.4%-52.6%）。虚弱在老年群体、妇女和社会经济地位较低的人中更为普遍，这是通过教育和家庭收入来衡量的。虚弱的人往往健康状况更差。我们还观察到一个区域的变化：脆弱的患病率往往是在东部比西部japon.Conclusions：这项研究提供了重要的证据，在日本老年人的脆弱的患病率，并发现社会人口特征，健康状况和地理区域的重大差异。
Background: Japan has the largest aging population in the world, thus, a focus on frailty is important in clinical geriatric practice. Using a nationally representative sample, this study provided national estimates of the prevalence of frailty among community-dwelling older Japanese people. We also examined variations in the prevalence by sociodemographic characteristics, health conditions, and geographical regions.Methods: Data came from the National Survey of the Japanese Elderly in 2012. The data were collected using a home visit and face-to-face interviews with trained interviewers. The sample consisted of 2206 adults aged >= 65 years. We used the widely accepted definition of physical frailty phenotype and calculated weighted estimates of the prevalence of frailty.Results: Overall estimated prevalence was 8.7 % (7.5 %-9.9 %) for frail, 40.8 % (38.7 %-42.9 %) for prefrail, and 50.5 % (48.4 %-52.6 %) for robust. Frailty was more prevalent in older groups, women, and those with lower socioeconomic status, which was measured by education and household income. Frail people tended to have worse health. We also observed a regional variation: frailty prevalence tended to be higher in eastern than western Japan.Conclusions: This study provides important evidence on the prevalence of frailty in older Japanese people and found substantial disparities by sociodemographic characteristics, health conditions, and geographical regions.
