Successful aging is a worldwide aim, but its related factors and instruments of measurement are currently hotly debated. To investigate the relationship between muscle strength and functional capacity, and its association with successful aging.
A population-based cross-sectional study was performed in Mataró (Spain). Included in the study were 313 subjects (153 men, 160 women) aged 70 years and over. Physical and cognitive functions were assessed, as well as muscle strength, nutritional status, lifestyle factors, and associated morbidities.
A state of successful aging (SA), defined as optimal functional and cognitive capacities with absence of cancer, stroke, cardiovascular or pulmonary chronic diseases, was found in 20% of women and 32% of men. SA was associated with higher muscle strength in comparison with the non-SA condition. Muscle strength measurements were higher in men, and decreased with age, poor balance, decreased functional capacity, and impaired cognitive status. It was also associated with higher academic level, regular exercise, and nutritional status in both genders. Multivariate analysis showed that independent variables related to SA were: hand grip, arthrosis, deafness and unipodal balance test, but not age or gender.
Muscle strength is positively associated with the successful aging condition, and may be one of its functional links, reflecting the integrated health status of old men and women. The systematic inclusion of the measurement of muscle strength may be helpful in clinical evaluation of the elderly.
成功老龄化是全球的目标，但目前其相关因素及测量工具备受争议。旨在研究肌肉力量与功能能力之间的关系，以及其与成功老龄化的关联。
在西班牙马塔罗进行了一项基于人群的横断面研究。研究纳入了313名年龄在70岁及以上的受试者（153名男性，160名女性）。评估了身体和认知功能、肌肉力量、营养状况、生活方式因素及相关疾病。
成功老龄化（SA）状态定义为功能和认知能力最佳且无癌症、中风、心血管或肺部慢性疾病，在20%的女性和32%的男性中发现。与非SA状态相比，SA与更高的肌肉力量相关。男性的肌肉力量测量值更高，且随年龄增长、平衡能力差、功能能力下降和认知状态受损而降低。它还与男女的更高学历、规律运动和营养状况相关。多变量分析表明，与SA相关的独立变量为：握力、关节病、耳聋和单脚平衡测试，但不是年龄或性别。
肌肉力量与成功老龄化状态呈正相关，可能是其功能联系之一，反映了老年男女的综合健康状况。系统纳入肌肉力量测量可能有助于老年人的临床评估。
