摘要：

目的: 探究江苏省部分地区不同性别成年人脂肪质量随年龄增长的变化情况以及不同年龄段人群体质量指数(body fat index,BMI)和脂肪质量之间的关系。方法: 收集2019年9月至2021年2月江苏省南京市、淮安市以及无锡市的体检人群数据,对符合纳入标准人群进行体格检查和体成分检测,并分析其脂肪质量随年龄变化情况。结果: 共收集2115名志愿者的基本信息,排除信息不全者46名,共纳入2069名进行研究分析。30岁以上成年人去脂体质量(fat free mass,FFM)随着年龄的增长呈现下降的趋势;30岁以上成年人的体脂肪量(body fat mass,BFM)、体脂百分比(percentage of body fat,PBF)、腰臀比(waist-hip ratio,WHR)和体脂指数(fat mass index,FMI)随着年龄的增长均呈现上升趋势,BFM、PBF和去脂体质量百分比(percentage of fat free mass,PFFM)在40岁出现显著上升,FFM和去脂体质量指数(fat free mass index,FFMI)在60岁开始出现显著下降。男性FMI在40岁出现显著上升,女性FMI从60岁出现显著上升。全年龄段成年人FFM随着BMI和腰围水平的升高呈上升趋势。结论: 随着年龄的增长男性和女性的BFM、PBF和WHR均呈现上升趋势。各年龄段成年男性FFM显著高于女性,女性BFM、FMI、PBF和内脏脂肪面积显著高于男性。全年龄段成年人FFM随着BMI和WHR升高呈上升趋势。

Objective: To explore the changes in fat mass with age in adult males and females in selected areas of Jiangsu Province,as well as the relationship between body fat index(BMI) and fat mass in different age groups.Methods: Data from physical examination participants in Nanjing,Huai'an,and Wuxi,Jiangsu province from September 2019 to February 2021 were collected,and physical and body composition examinations were conducted for eligible individuals. Results: Basic information was collected from 2 115 volunteers,among whom 46 with incomplete information were excluded,2 069 individuals were enrolled into the analysis. Regardless of gender,fat free mass(FFM) decreased with age in adults over 30 years of age. Body fat mass(BFM),percentage of body fat(PBF),waist-hip ratio(WHR),and fat mass index(FMI) all showed an increasing trend with age in adults over 30 years of age,with a significant increase in BFM,PBF,and FFM percentage at the age of 40. FFM and FFMI began to significantly decrease at the age of 60. Male body fat index showed a significant increase at the age of 40,while female body fat index showed a significant increase at the age of 60. FFM showed an increasing trend with higher BMI and waist circumference levels in adults of all ages.Conclusion: With increasing age,both males and females show an upward trend in BFM,PBF,and WHR. Among different age groups,adult males exhibit significantly higher FFM than females,while females have significantly higher BFM,FMI,PBF,and visceral fat area than males. Across all age groups,FFM increases along with BMI and WHR.
