With the increase in life expectancy, the elderly Brazilian population has grown considerably. However, longevity is usually accompanied by problems such as the loss of functional capacity, cognitive decline, and deterioration in anthropometric parameters, particularly among those living in long-term care facilities. We analyzed the relationship among cognitive performance, anthropometry, and functional capacity in institutionalized elderly individuals.
In a sample of 38 older adults (20 men, 18 women) aged 73.4 ± 8.1 years, data regarding anthropometric and functional measurements as well as the Mini-Mental State Examination were collected. Functional tests were based on a battery adapted from the Functional Fitness Test. The independent t-test and χ test were applied. P < 0.05 was set as the significance threshold.
The rate of cognitive impairment among obese individuals (78.6%) differed from that among eutrophic subjects (45.8%), but there was no difference between sexes. There was a significant positive correlation between handgrip strength and Mini-Mental State Examination score, and the scores of the timed up-and-go test and the sitting-rising test were negatively correlated with Mini-Mental State Examination score.
Cognitive impairment in the elderly living in long-term care facilities was more pronounced and frequent in obese individuals. This study also demonstrated that better functional capacity reflects better cognitive performance.
随着预期寿命的增加，巴西老年人口大幅增长。然而，长寿通常伴随着功能能力丧失、认知衰退和人体测量参数恶化等问题，尤其是在长期护理机构中的老年人。我们分析了机构养老老年人的认知表现、人体测量和功能能力之间的关系。
在38名年龄为73.4±8.1岁的老年人（20名男性，18名女性）样本中，收集了人体测量和功能测量数据以及简易精神状态检查表数据。功能测试基于改编自功能性体能测试的一组测试。应用独立t检验和χ检验。设定P<0.05为显著性阈值。
肥胖个体的认知障碍发生率（78.6%）与营养正常个体（45.8%）不同，但性别之间无差异。握力与简易精神状态检查表得分之间存在显著正相关，计时起立行走测试和坐立测试得分与简易精神状态检查表得分呈负相关。
长期护理机构中的老年人，肥胖个体的认知障碍更为明显和常见。本研究还表明，更好的功能能力反映了更好的认知表现。
