摘　　要：目的采用定量CT(QCT)研究不同体质量指数(body mass index,BMI)青年人群的各体质成分、腰臀围与握力的相关性。方法收集2021年4–7月于我院进行胸部体检QCT的1310例青年人群资料,并计算其BMI,按BMI分为4组:偏瘦组(BMI<18.5 kg/m2);正常组(18.5 kg/m2≤BMI<24 kg/m2);超重组(24 kg/m2≤BMI<28 kg/m2);肥胖组(BMI≥28 kg/m2)。将原始数据传至QCT Mindways Pro 6.1软件后处理测量L2椎体的各体质成分脂肪含量(面积),包括腹部总脂肪(total adipose tissue,TAT)、腹腔内脂肪(visceral adipose tissue,VAT)、皮下脂肪(subcutaneous adipose tissue,SAT)、腹腔内脂肪/皮下脂肪(腹脂比,VAT/SAT)。采用CAMRY EH101型数字握力计测量握力。对数据进行统计学分析,并探讨不同BMI的各体质成分、腰围、臀围与握力的相关性;同时对正常、超重两组按照年龄进行分层分析。结果正常组男性在21~40岁身高、体质量、臀围与握力呈正相关,36~40岁SAT与握力呈负相关,而VAT/SAT与其呈正相关;女性在21~25岁SAT与握力呈负相关,而VAT、VAT/SAT与其呈正相关,26~40岁身高、体质量、臀围与握力呈正相关,36~40岁VAT/SAT与握力呈正相关。超重组男性在21~25岁臀围、体质量与握力呈正相关,26~30岁TAT、腰臀比、腰高比与握力均呈负相关,31~40岁身高、体质量与握力呈正相关,而腰臀比、腰高比与其呈负相关,且在31~35岁臀围与握力呈正相关;女性在21~25岁腰围、臀围、腰高比与握力呈正相关,26~30岁身高、体质量与握力呈正相关,31~35岁TAT、SAT、腰围、腰臀比、腰高比与握力均呈负相关,36~40岁SAT、腰高比与握力呈负相关,VAT、VAT/SAT、身高、体质量与其呈正相关。偏瘦组男女身高、体质量与握力呈正相关,且偏瘦组女性臀围与握力也呈正相关。肥胖组男性TAT、VAT、腰高比与握力呈负相关,女性则无相关性。结论不同BMI的青年人群的腹部脂肪含量与握力关系密切,对于青年人Objective To study with quantitative computed tomography(QCT)the correlation between grip strength and physical composition and waist and hip circumferences in young people with different body mass indexes(BMIs).Methods A total of 1310 young people who came to West China Hospital,Sichuan University for physical checkups and underwent chest QCT at our hospital from April to July 2021 were included in the study.Their data were collected and their BMIs were calculated.The subjects were divided according to their BMIs into 4 groups,underweight group(BMI<18.5 kg/m2),normal-weight group(18.5 kg/m2≤BMI<24 kg/m2),overweight group(24 kg/m2≤BMI<28 kg/m2),and obesity group(BMI≥28 kg/m2).The raw data were uploaded to QCT Mindways Pro 6.1 software to be processed for measurement of the fat content(area)of the physical components of the L2 vertebral body,including total adipose tissue(TAT),visceral adipose tissue(VAT),subcutaneous adipose tissue(SAT),and abdominal fat ratio,or VAT/SAT.Grip strength was measured with CAMRY EH101 digital grip dynamometer.Statistical analysis of the data was performed,and the correlations between grip strength and various physical components,waist circumference,and hip circumference in subjects of different BMIs were examined.In addition,stratified analysis of normal-weight and overweight subjects of different age groups was conducted.Results In the normal-weight group,height,body mass,hip circumference and grip strength were positively correlated with grip strength in males aged 21-40 years,SAT was negatively correlated with grip strength in males aged 36-40 years,and VAT/SAT was positively correlated with grip strength in males aged 36-40 years.In normal-weight females aged 21-25 years,SAT was negatively correlated with grip strength,while VAT and VAT/SAT were positively correlated with grip strength.In normal-weight females aged 26-40 years,height,body mass,and hip circumference were positively correlated with grip strength.In normal-weight females aged 36-40 years,VAT/SAT was positively
