Although the population with intellectual disabilities (ID) is increasingly growing older, there seems to be an early onset of functional decline in this group, which could be explained by frailty. We used data from the Healthy Aging and Intellectual Disability study (HA-ID) to measure frailty in people with ID. Frailty was measured with an adapted version of the frailty index, consisting of 50 health and age related deficits. We were the first to measure frailty with a frailty index in this population, and therefore its validity, in terms of predictive value, needed to be established. In the current article we provide an overview of the design of the frailty index and its relation with adverse health outcomes. In a nearly representative study population of 982 50-plus older adults with ID, we studied the prevalence of frailty and its validity over a 3-year follow-up period. Results show that people with ID were earlier and more severely frail than people from the general population. Frailty was related to early mortality, to disabilities in daily functioning and mobility, to increased medication use, and increased care intensity, but not to hospitalization. Using a hypothetical model, we identify possible interventions to increase the healthy life years in people with ID.
尽管智障人群的老龄化趋势日益明显，但该群体似乎出现了功能衰退的早期迹象，这可能是由身体虚弱所致。我们利用健康老龄化与智障研究（HA-ID）的数据来测量智障人群的身体虚弱程度。身体虚弱程度通过虚弱指数的一个改编版本来衡量，该指数由50项与健康和年龄相关的缺陷组成。我们是首个在该人群中使用虚弱指数来测量身体虚弱程度的，因此，就预测价值而言，其有效性需要得到验证。在本文中，我们概述了虚弱指数的设计及其与不良健康结果的关系。在一个近982名50岁及以上智障老年人的具有代表性的研究人群中，我们研究了身体虚弱的患病率及其在3年随访期内的有效性。结果显示，与普通人群相比，智障人群更早且更严重地出现身体虚弱。身体虚弱与早期死亡率、日常功能和行动能力残疾、用药增加以及护理强度增加有关，但与住院无关。通过一个假设模型，我们确定了可能的干预措施，以增加智障人群的健康寿命年数。
