The very low physical fitness levels of people with intellectual disabilities (ID) may influence their life expectancy. Therefore, we investigated the predictive value of physical fitness for survival in older adults with intellectual disabilities.
In the Healthy Ageing and Intellectual Disabilities (HA-ID) study,the physical fitness levels of 900 older adults (≥50 years; 61.5 ± 8.1 years) were measured at baseline. All-cause mortality was collected over a 5-year follow-up period. Cox proportional hazard models were used to determine the association between each physical fitness test and survival, adjusted for age, sex, level of ID, and Down syndrome.
The physical fitness components that were independently predictive for survival were manual dexterity (HR = 0.96 [0.94-0.98]), visual reaction time (HR = 1.57 [1.28-1.94]), balance (HR = 0.97 [0.95-0.99]), comfortable gait speed (HR = 0.65 [0.54-0.78]), fast gait speed (HR = 0.81 [0.72-0.91]), grip strength (HR = 0.97 [0.94-0.99]) and cardiorespiratory fitness (HR = 0.997 [0.995-0.999]), with a better physical fitness showing a lower mortality risk.
We showed for the first time that physical fitness was independently associated with survival in older adults with intellectual disabilities. Improving and maintaining physical fitness must become an essential part of care and support for this population.
智力障碍者（ID）的身体体能水平极低可能会影响他们的预期寿命。因此，我们研究了身体体能对智力障碍老年患者生存的预测价值。
在“健康老龄化与智力障碍”（HA-ID）研究中，对 900 名年龄在 50 岁及以上（≥50 岁；61.5±8.1 岁）的老年人在基线时测量了身体体能水平。在 5 年的随访期间收集了全因死亡率。使用 Cox 比例风险模型来确定每个体能测试与生存之间的关联，调整因素包括年龄、性别、智力障碍程度和唐氏综合征。
独立预测生存的体能组成部分是手的灵巧性（HR=0.96[0.94-0.98]）、视觉反应时间（HR=1.57[1.28-1.94]）、平衡能力（HR=0.97[0.95-0.99]）、舒适的步行速度（HR=0.65[0.54-0.78]）、快速步行速度（HR=0.81[0.72-0.91]）、握力（HR=0.97[0.94-0.99]）和心肺适能（HR=0.997[0.995-0.999]），更好的体能表现出更低的死亡风险。
我们首次表明，身体体能与智力障碍老年患者的生存独立相关。改善和维持身体体能必须成为该人群护理和支持的重要组成部分。
