本研究的目的是分析从中年到老年早期缺乏身体活动对75岁时功能能力的影响。体力活动的测量都是从50岁到60岁到70岁的累积活动，并在三个不同的时间点。387名男性和女性出生于1914年，生活在哥本哈根县西部的七个城市，在1964年，1974年，1984年和1989年进行了为期25年的检查。进行分析时，将缺乏身体活动作为自变量（每个时间点分别累积），将吸烟、性别、学校教育、家庭组成、基线慢性病和70岁时的功能能力作为可能的混杂因素。70岁时缺乏身体活动与75岁时残疾之间有很强的关联。然而，分析显示，当调整70岁时的功能能力时，从50岁到60岁再到70岁的累积身体不活动对75岁时的残疾没有影响。缺乏身体活动是老年人残疾的一个危险因素。因此，应鼓励老年人在整个衰老过程中进行和保持体育锻炼。
The aim of this study is to analyze the impact of physical inactivity from middle age to early old age on functional ability at age 75. Physical activity is measured both as cumulated activity from age 50 to 60 to 70 and at three separate points in time.Three hundred eighty-seven men and women born in 1914 and living in seven municipalities in the western part of the County of Copenhagen were followed for 25 years with examinations in 1964, 1974, 1984 and 1989. Analyses were conducted with physical inactivity as an independent variable (accumulated and separately for each point in time) and smoking, sex, school education, household composition, chronic disease at baseline and functional ability at age 70 as possible confounders. There was a strong association between physical inactivity at age 70 and disability at age 75. However, the analyses showed no effect of cumulated physical inactivity from age 50 to 60 to 70 on disability at age 75 when adjusting for functional ability at age 70. Physical inactivity is a risk factor for disability among old people. Thus, old people should be encouraged to take up and maintain physical training throughout the aging process.
