研究目的：建立我国大学生的肱三头肌和肩胛下皮褶厚度正常值并估测体成分。研究方法：对11省市17611名19～22岁男女大学生进行体成分分析并作分组差值检验，利用百分位数法建立正常值。主要结果和结论：我国大学生在皮褶厚度和体脂率、瘦体重等方面存在明显的城乡差异和地区间差异。体格发育和体成分指标间存在密切的相关关系。分别为男女生建立了两处皮褶厚度的百分位数正常值。建议：该正常值可广泛应用于对大学生人群进行营养状况评价，筛查肥胖和营养不良。
Objectives: To establish the normal thickness of triceps and subscapular skinfolds of undergraduates in our country and estimate the body composition. Methods: The body composition of 17611 male and female college students from 19 to 22 years old in 11 provinces and municipalities were analyzed and grouped difference test was used to establish the normal value by the percentile method. Main results and conclusion: There are obvious differences between urban and rural areas and among different regions in terms of skinfold thickness, body fat percentage and lean body mass. There is a close correlation between physical development and body composition index. Two normal values of percentile of skinfold thickness were established for boys and girls respectively. Recommendation: The normal value can be widely used to assess the nutritional status of college students, screening for obesity and malnutrition.
