背景。了解影响中年身体表现的健康、行为和社会因素可能为了解老年虚弱的起源和老年人群未来的健康提供线索。作者评估了一个由 53 岁英国男性和女性组成的大型具有代表性的前瞻性队列中的肌肉力量、姿势控制和椅子上升表现，并与功能限制、体型、健康和活动以及社会经济条件相关。方法。护士们在英格兰、苏格兰和威尔士的 2984 名男性和女性的家中采访了他们，并对其中 2956 名进行了体检。客观测量包括身高、体重和三项身体机能测试：握力、单腿站立平衡时间以及完成 10 次椅子起立的时间。使用结构化调查问卷获得功能限制（行走困难、爬楼梯、抓握和跌倒）、健康状况、体力活动和社会阶层。结果。那些在体能测试中得分最差的人，上肢和下肢功能受限的比例较高。与男性相比，女性的握力较弱，平衡时间稍差，椅子上升时间也稍差。对于女性来说，健康问题和体力活动水平低导致所有三项指标的身体表现都很差。对于男性来说，体力活动是主要影响因素。较重的体重和较差的社会经济条件导致较差的平衡和椅子起立时间。结论。在这个具有代表性的中年群体中，身体机能水平差异很大，女性与男性相比处于严重劣势。一般来说，生活在社会经济条件较差、体重较大、健康状况较差和生活方式不活跃的男性和女性的身体表现较差。这些发现支持控制体重过重、有效的健康干预措施以及在衰老过程中保持积极生活方式的建议。
Background. Understanding the health, behavioral, and social factors that influence physical performance in midlife may provide clues to the origins of frailty in old age and the future health of elderly populations. The authors evaluated muscle strength, postural control, and chair rise performance in a large representative prospective cohort of 53-year-old British men and women in relation to functional limitations, body size, health and activity, and socioeconomic conditions.Methods. Nurses interviewed 2984 men and women in their own homes in England, Scotland, and Wales and conducted physical examinations in 2956 of them. Objective measures were height, weight, and three physical performance tests: handgrip strength, one-legged standing balance time, and time to complete 10 chair rises. Functional limitations (difficulties walking, stair climbing, gripping, and falls), health status, physical activity, and social class were obtained using a structured questionnaire.Results. Those with the worst scores on the physical performance tests had higher rates of functional limitations for both upper and lower limbs. Women had much weaker handgrip strength, somewhat poorer balance time, and only slightly poorer chair rise time compared with men. In women, health problems and low levels of physical activity contributed to poor physical performance on all three measures. In men, physical activity was the predominant influence. Heavier weight and poorer socioeconomic conditions contributed to poorer balance and chair rise times.Conclusions. In this representative middle-aged group, physical performance levels varied widely, and women were seriously disadvantaged compared with men. In general, physical performance was worse for men and women living in poorer socioeconomic conditions with greater body weight, poorer health status, and inactive lifestyles. These findings support recommendations for controlling excess body weight, effective health interventions, and the maintenance of active lifestyles during aging.
