本文观察了干休所离退休干部和老人公寓托养老人的体脂含量、体脂分布、肥胖检出率以及热能需要量与热能摄取量，并对此进行了比较。干休所老人８３人，平均年龄６４．３±３．８岁；公寓托养老人４７人，平均年龄７２．０±１１．４岁。测定结果显示，体重、腰臀比率、体脂含量、肥胖检出率、热能摄取量、热能摄取超量人数（％），干休所老人均显著高于公寓老人。故认为，热能摄取超量是干休所老人体脂含量和肥胖检出率高的主要原因，提出低热量饮食是减少体脂含量和降低肥胖发生率的有效方法。本文还就测量身围评价体脂含量、体脂分布和体脂含量变化的意义进行了讨论。
In this paper, the body fat content, body fat distribution, obesity detection rate, heat energy requirement and heat energy intake of retired cadres and old-age apartments are observed and compared. Eighty-three elderly people were living on average, and the average age was 64.3±3.8 years. The apartment supported 47 elderly people with an average age of 72.0±11.4 years. The results showed that body weight, waist-to-hip ratio, body fat content, obesity detection rate, heat energy intake, and calorie intake excess (%) were significantly higher in elderly off-site residents than those in apartments. Therefore, it is believed that the excessive intake of heat energy is the main reason for the high body fat content and obesity detection rate of elderly people in dry breaks. It is proposed that low-calorie diet is an effective method to reduce body fat content and reduce the incidence of obesity. This article also discusses the significance of measuring body fat content, body fat distribution and body fat content in body circumference measurements.
