In Portugal, the burden of pre-frailty and frailty in community-dwelling older adults is still unknown. The purpose of this study is to estimate the frequency of frailty in a Portuguese sample with ≥ 65years and to evaluate its associated factors. We also intend to identify which criterion has more impact on the diagnosis of frailty.
1457 older adults with ≥ 65years from the Nutrition UP 65 study were evaluated in a cross-sectional analysis. Frailty was identified according to Fried et al. by the presence of three or more of the following factors: unintentional weight loss, self-reported exhaustion, slowness, weakness and low physical activity. Pre-frailty was defined as the presence of one or two of these criteria. The association between individuals' characteristics and frailty status was analysed through logistic regression analysis.
The frequency of pre-frailty and frailty is 54.3% and 21.5%, respectively. In older adults classified as pre-frail or frail, 76.7% presented weakness and 48.6% exhaustion. In multivariate analyses, frailty was associated with age >75, lower education level, being single, divorced or widower, being professionally inactive, poor self-perception of health status, not drinking alcohol, being obese and undernourished or at undernutrition risk.
This condition is very prevalent in Portuguese older adults, one fifth are frail whereas half are pre-frail. Weakness identified by low handgrip strength is the most prevalent criterion in pre-frail and frail Portuguese older adults.
在葡萄牙，社区居住的老年人中衰弱前期和衰弱的负担尚不清楚。本研究的目的是评估≥65 岁的葡萄牙样本中衰弱的频率，并评估其相关因素。我们还旨在确定哪个标准对衰弱的诊断有更大的影响。
在一项横断面分析中，对营养 UP 65 研究中≥65 岁的 1457 名老年人进行了评估。根据 Fried 等人的标准，通过存在以下三个或更多因素来确定衰弱：非故意体重减轻、自我报告的疲惫、缓慢、虚弱和低身体活动。衰弱前期定义为存在这些标准中的一个或两个。通过逻辑回归分析来分析个体特征与衰弱状态之间的关系。
衰弱前期和衰弱的发生率分别为 54.3%和 21.5%。在被归类为衰弱前期或衰弱的老年人中，76.7%存在虚弱，48.6%存在疲劳。在多变量分析中，衰弱与年龄>75 岁、教育水平较低、单身、离婚或丧偶、职业不活跃、健康自评较差、不饮酒、肥胖、营养不良或营养不足风险有关。
这种情况在葡萄牙老年人中非常普遍，五分之一的人衰弱，而一半的人衰弱前期。通过低握力识别的虚弱是葡萄牙衰弱前期和衰弱老年人中最常见的标准。
