The article seeks to investigate patterns of performance and relationships between grip strength, gait speed and self-rated health, and investigate the relationships between them, considering the variables of gender, age and family income. This was conducted in a probabilistic sample of community-dwelling elderly aged 65 and over, members of a population study on frailty. A total of 689 elderly people without cognitive deficit suggestive of dementia underwent tests of gait speed and grip strength. Comparisons between groups were based on low, medium and high speed and strength. Self-related health was assessed using a 5-point scale. The males and the younger elderly individuals scored significantly higher on grip strength and gait speed than the female and oldest did; the richest scored higher than the poorest on grip strength and gait speed; females and men aged over 80 had weaker grip strength and lower gait speed; slow gait speed and low income arose as risk factors for a worse health evaluation. Lower muscular strength affects the self-rated assessment of health because it results in a reduction in functional capacity, especially in the presence of poverty and a lack of compensatory factors.
本文旨在研究握力、步速与自评健康之间的表现模式及关系，并考虑性别、年龄和家庭收入等变量来探究它们之间的关系。这是在一项针对65岁及以上社区居住老年人的概率抽样研究中进行的，这些老年人是一项关于衰弱的人群研究的成员。共有689名无痴呆症认知缺陷迹象的老年人接受了步速和握力测试。组间比较基于低、中、高速度和力量。自评健康状况采用5分制进行评估。男性和较年轻的老年人在握力和步速方面的得分显著高于女性和最年长的老年人；最富有的人在握力和步速方面的得分高于最贫穷的人；80岁以上的女性和男性握力较弱，步速较慢；步速慢和低收入是健康评估较差的风险因素。较低的肌肉力量会影响对健康的自评，因为它会导致功能能力下降，尤其是在贫困和缺乏补偿因素的情况下。
