BACKGROUND
Overweight/obesity and poor physical fitness are two prevalent lifestyle-related problems in older adults with intellectual disabilities, which each require a different approach. To improve healthy ageing, we assessed whether fatness or fitness is more important for survival in older adults with intellectual disabilities.
METHODS
In the HA-ID study, we measured obesity and fitness of 874 older adults with intellectual disabilities (61.4 ± 7.8 years). All-cause mortality was assessed over a 5-year follow-up period.
RESULTS
Fitness, but not obesity, was significantly related to survival (HR range of 0.17-0.22). People who were unfit were 3.58 (95% CI = 1.72-7.46) to 4.59 (95% CI = 1.97-10.68) times more likely to die within the follow-up period than people who were fit, regardless of obesity.
CONCLUSION
This was the first study to show that being fit is more important for survival than fatness in older adults with intellectual disabilities. The emphasis should, therefore, shift from weight reduction to improving physical fitness.
背景
超重/肥胖和身体状况不佳是智力障碍老年人中两种普遍存在的与生活方式相关的问题，两者都需要采取不同的方法。为了促进健康老龄化，我们评估了在智力障碍老年人中，肥胖和健康状况对生存的重要性。
方法
在 HA-ID 研究中，我们测量了 874 名智力障碍老年人（61.4±7.8 岁）的肥胖和健康状况。在 5 年的随访期间评估全因死亡率。
结果
健康状况，但不是肥胖，与生存显著相关（HR 范围为 0.17-0.22）。无论肥胖与否，不适合的人在随访期间死亡的可能性是健康的人的 3.58（95%CI=1.72-7.46）至 4.59（95%CI=1.97-10.68）倍。
结论
这是第一项表明在智力障碍老年人中，健康状况比肥胖对生存更重要的研究。因此，重点应该从减肥转移到提高身体的健康状况。
