摘要

目的探讨上海地区老年人小腿围度与骨骼肌质量、力量和功能的关系。方法从我院体检中心招募401例老年人，平均年龄(71.8±7.4)岁，其中男性202例，女性199例。采用生物电阻抗法测定脂肪组织、骨骼肌质量(SMM)和阑尾骨骼肌质量(ASM)。计算ASM指数(ASM/height2)和SMM指数(SMM/height2)。通过检测步态速度(m/s)测量肌肉功能。肌肉力量采用电子手测力仪测定握力(HGS)，优势手握力3次取最大值。测量身高、体重、右小腿围和腰围。结果男性的身高、体重、ASM、ASM/height2、SMM、SMM/height2、HGS均显著高于女性(P<0.01);女性脂肪组织明显高于男性(P<0.05)。年龄、体重指数、小腿围、腰围、步态速度差异无统计学意义(P=0.426, P=0.143, P=0.425, P=0.093, P=0.143)。小腿围与身高、体重、BMI、腰围、ASM、ASM/height2、脂肪组织、握力、SMM、SMM/height2呈线性相关(P=0.001、P<0.001、P<0.001、P<0.001、P<0.001、P<0.001、P=0.003、P<0.001、P<0.001)。小腿围与步速、年龄无线性相关(P=0.818, P=0.078)。多元逐步回归分析显示，身高、BMI、ASM/height2和SMM与小腿围相关。结论男性骨骼肌质量和力量高于女性，女性脂肪组织高于男性。骨骼肌质量是影响小腿围度的重要因素。骨骼肌力量和小腿围之间呈线性相关。关键词:小腿围;手的力量;骨骼肌质量

Relationship between calf circumference and skeletal muscle mass, strength and function in the elderly

Objective To investigate the relationship between calf circumference and skeletal muscle mass, strength and function in the elderly in Shanghai. Methods A total of 401 old people were recruited from physical examination centers in our hospital with the mean age of (71.8±7.4) years, including 202 males and 199 females.Adipose tissue, skeletal muscle mass (SMM) and appendicular skeletal muscle mass (ASM) were measured by bioelectrical impedance analysis. The ASM index (ASM/height2) and SMM index (SMM/height2) were calculated.Muscle function was measured by testing gait speed (m/s). Muscle strength was measured by handgrip strength(HGS) using an electronic hand dynamometer, with the dominant hand gripping for three times and taking the maximum value.Height, weight, right calf circumference and waist circumference were measured. Results Height, weight, ASM, ASM/height2, SMM, SMM/height2 and HGS were significantly higher in men than in women (P<0.01); adipose tissue was significantly higher in women than in men (P<0.05). The age, body mass index, calf circumference, waist circumference and gait speed were not statistically different (P=0.426, P=0.143, P=0.425, P=0.093, P=0.143). There were linear correlations between calf circumference and height, weight, BMI, waist circumference, ASM, ASM/height2, adipose tissue, grip strength, SMM and SMM/height2 (P=0.001, P<0.001, P<0.001, P<0.001, P<0.001, P<0.001, P<0.001, P=0.003, P<0.001, P<0.001). There was no linear correlation between calf circumference and pace and age (P=0.818, P=0.078). Multiple stepwise regression analysis showed that height, BMI, ASM/height2 and SMM were correlated with the calf circumference. Conclusions Skeletal muscle mass and strength are higher in men than in women, while adipose tissue is higher in women than in men. Skeletal musle mass is an important factor affecting the calf circumference. There is a linear correlation between skeletal muscle strength and calf circumference. Key words: Calf circumference; Hand strength; Skeletal muscle mass

期刊介绍： The Chinese Journal of Clinical Nutrition was founded in 1993. It is the first professional academic journal (bimonthly) in my country co-sponsored by the Chinese Medical Association and the Chinese Academy of Medical Sciences to disseminate information on clinical nutrition support, nutrient metabolism, the impact of nutrition support on outcomes and "cost-effectiveness", as well as translational medicine and nutrition research. It is also a professional journal of the Chinese Medical Association's Parenteral and Enteral Nutrition Branch. The purpose of the Chinese Journal of Clinical Nutrition is to promote the rapid dissemination of knowledge on nutrient metabolism and the rational application of parenteral and enteral nutrition, focusing on the combination of multidisciplinary and multi-regional field investigations and clinical research. It mainly reports on nutritional risk screening related to the indications of parenteral and enteral nutrition support, "cost-effectiveness" research on nutritional drugs, consensus on clinical nutrition, guidelines, expert reviews, randomized controlled studies, cohort studies, glycoprotein and other nutrient metabolism research, systematic evaluation of clinical research, evidence-based case reports, special reviews, case reports and clinical experience exchanges, etc., and has a special column on new technologies related to the field of clinical nutrition and their clinical applications.
