摘要： 目的 了解社区老人随年龄增长人体成分的变化特点,为老化相关疾病的防治提供理论支持。 方法 选取2020年10~12月无锡市某社区60岁及以上老人1017名,按年龄分为60~69岁组(n=214)、70~79岁组(n=633)、≥80岁组(n=170),利用生物电阻抗法检测人体成分,比较3组人体成分的差异。 结果 老年人随年龄增长,脂肪含量、BMI、腰围、腰臀比、体脂百分比无显著变化(P均>0.05)。老年女性随年龄增长肌肉总量、骨质含量、肢体各区域肌肉及骨质含量减少(P均<0.01),而在老年男性中差异无统计学意义(P均>0.05)。老年男性肌肉总量、骨质含量、肢体各区域肌肉及骨质含量高于同一年龄段的女性(P<0.001),脂肪含量低于同一年龄段的女性(P均<0.05)。 结论 增龄引起老年人肌肉及骨质含量的减少具有性别差异,在老年女性中多见,而增龄对脂肪含量的影响不大。

Abstract: Objective To describe the age-dependent changes in body composition in Chinese elderly who are dwelling in the community with independent living ability. Methods Cross-sectional data from 1017 community-dwelling elderly conducting physical examination at Wuxi Meicun Community Health Service Center from October to December 2020 were analyzed. The research subjects were divided into 3 groups according to their age (60-69 years old; 70-79 years old; ≥80 years old). Body composition parameters including height,body weight, body mass index (BMI),body fat percentage, waist-hip ratio, body fat content, body muscle mass,skeletal muscle masses and bone mineral content were measured with a bioelectrical impedance analyser. Results There were no significant changes in fat content, BMI, waist circumference, waist hip ratio and body fat percentage with the increase of age (P>0.05).The muscle masses and bone contents of whole body,the trunk,upper and lower limbs were decreased with the increase of age in women (P<0.01),but there was no difference in men (P> 0.05). The muscle masses and bone contents of whole body,the trunk,upper and lower limbs in men were higher than those in women of the same age group (P<0.001), while the fat content in women was higher than that in men of the same age group (P<0.05). Conclusions The decrease of muscle and bone content caused by aging is affected by gender, which is common in women, but aging has little effect on fat content.

Key words: community elderly, body composition, body fat content, muscle mass, bone mineral content
