Objective: The aim was to compare the body composition using classical anthropometry and bioelectric impedance in university students of a Peruvian university. Method: a correlational, cross-sectional study with a research sample of 152 students (77 men and 75 women) enrolled in the 2018-II period with an average age of 20.45 ± 3.63 years. The body mass index and anthropometric measurements were calculated for the anthropometric method. The Yuhasz (1974) equation was used to determine the body fat percentage. The electrical bioimpedance method implemented the tetrapolar multi-frequency direct segmental measurement analyzer Inbody 120. Pearson coefficient was used to establish the correlation, and the Bland Altman graphical method and stability index were used for concordance. The data were analyzed using the statistical software application IBM SPSS Statistics, version 27.0. A level of significance (p <0.05) was used for all analyzes. Results: there is a strong statistically significant correlation (p<0.01 and r = 0.95) between the anthropometric and electrical bioimpedance methods to determine body fat percentage. In addition, there is a good agreement according to the Bland Altman graphical method, reinforced by the stability index to complement the interpretation (IE = 95%). Conclusions: Both methods are interchangeable with each other, so they can be used indistinctly in this type of population to determine body fat percentage.
