The aim of this study is to find out decision index standards of college students' nutrition degree. 593 college students between 19-22 years old (224 male and 239 female) were randomly selected and measured from several aspects, including height, weight, waist circumference and thickness of four skin folds (triceps skin fold, subscapular skin fold, abdominal skin fold, gastrocnemius skin fold). B-1/2 (H-w) calculation method is applied to calculate relevant physical indexes; Changling formula of density estimating (D) and modified Brozek formula are used to calculate body fat percentage (BF%). After variance analysis, there are significant differences between mean values of total skin fold thickness of each group. The difference increases with the increasing of group limitation. According to the corresponding relationship between B-1/2(H-w) and BF%, it can be concluded that the new body mass index standard of college students' nutrition degree is scientific and practical.
