背景：老年人的虚弱增加了他们的脆弱性，并导致更大的不良事件风险。根据各种研究，65岁及以上人群中虚弱综合征的患病率在3%至37%之间，具体取决于年龄和性别。步行速度本身被认为是老年人健康状况和生存的一个简单指标。在初级保健咨询中检测虚弱可以帮助改善老年人的护理，步行速度可能是一个指标，可以促进初级保健中虚弱的早期诊断。这项工作的目的是估计虚弱综合征的患病率和步行速度在城市人口年龄在65岁及以上，并分析这两个指标之间的关系，从早期诊断的角度脆弱的初级保健setting.Methods：人口队列的人年龄在65岁及以上的两个城市社区在北方马德里（西班牙）。横截面分析。采用二元Logistic回归进行双变量和多变量分析，以研究与虚弱相关的变量。使用0.4和1.4 m/s之间的不同截止点来研究该人群的步行速度。结果：研究样本包括1,327名年龄在65岁及以上的个体，平均年龄为75.41 +/- 7.41岁; 53.4%为女性。研究人群的估计虚弱为10.5% [95% CI：8.9-12.3]。虚弱随着年龄的增长而增加（OR = 1.14; 95%CI：1.10-1.19），并与自我评价的健康状况较差（OR = 2.52; 95%CI：1.43-4.44）、处方药物数量（OR = 1.17; 95%CI：1.08-1.26）和残疾（OR = 6.58; 95%CI：3.92-11.05）相关。42.6%的病例和56.4%的75岁及以上人群的步行速度小于0.8 m/s。大于0.9 m/s的步行速度排除了研究样本中的虚弱。75岁及以上的人，步行速度
Background: Frailty in the elderly increases their vulnerability and leads to a greater risk of adverse events. According to various studies, the prevalence of the frailty syndrome in persons age 65 and over ranges between 3% and 37%, depending on age and sex. Walking speed in itself is considered a simple indicator of health status and of survival in older persons. Detecting frailty in primary care consultations can help improve care of the elderly, and walking speed may be an indicator that could facilitate the early diagnosis of frailty in primary care. The objective of this work was to estimate frailty-syndrome prevalence and walking speed in an urban population aged 65 years and over, and to analyze the relationship between the two indicators from the perspective of early diagnosis of frailty in the primary care setting.Methods: Population cohort of persons age 65 and over from two urban neighborhoods in northern Madrid (Spain). Cross-sectional analysis. Bivariate and multivariate analysis with binary logistic regression to study the variables associated with frailty. Different cut-off points between 0.4 and 1.4 m/s were used to study walking speed in this population. The relationship between frailty and walking speed was analyzed using likelihood ratios.Results: The study sample comprised 1,327 individuals age 65 and older with mean age 75.41 +/- 7.41 years; 53.4% were women. Estimated frailty in the study population was 10.5% [95% CI: 8.9-12.3]. Frailty increased with age (OR = 1.14; 95% CI: 1.10-1.19) and was associated with poor self-rated health (OR = 2.52; 95% CI: 1.43-4.44), number of drugs prescribed (OR = 1.17; 95% CI: 1.08-1.26) and disability (OR = 6.58; 95% CI: 3.92-11.05). Walking speed less than 0.8 m/s was found in 42.6% of cases and in 56.4% of persons age 75 and over. Walking speed greater than 0.9 m/s ruled out frailty in the study sample. Persons age 75 and older with walking speed
