尽管随年龄增长,人们经常会轻度发胖,但却有肢体皮下脂肪厚度减少和躯干皮下脂肪减少。随年龄腹围增加,说明脂肪积累是在腹内而不是在皮下。过去没有技术能够测量体内脂肪和无脂肪组织的分布,因而不可能证明在人的晚年脂肪的内部再分配或测定器官和肌肉群的无脂肪组织降低的情况。作者将CT应用于身体结构的研究,并发现它能测量出其他技术所不能测到的东西。CT可在身体任何切面清晰地描绘脂肪和肌肉。本研究是用CT测定中年和老年男性身体结构的差异,特别是脂肪分布、肌肉区和脂肪及无脂肪组织密度的年龄差异。
Although people become mildly obese as they grow older, they have reduced subcutaneous fat thickness and decreased trunk subcutaneous fat. Abdominal circumference increases with age, indicating that fat accumulation is in the abdomen rather than subcutaneous. In the past, no technique was available to measure the distribution of body fat and non-adipose tissue, making it impossible to justify the redistribution of fat in the elderly or the reduction of fat-free tissues in organs and muscle groups. The author applies CT to body structure research and finds that it can measure what can not be measured by other techniques. CT can clearly depict fat and muscle in any aspect of the body. This study used CT to determine the differences in body structure of middle-aged and older men, in particular age distribution of fat distribution, muscle area and fat and adipose tissue density.
