Introduction: Currently, there are no formulas to estimate the percentage of fat by segments of the body from anthropometric measurements. The objective of this work was to correlate the percentage of arm fat mass (obtained through segmental bioimpedance) with anthropometric measurements, to generate a prediction formula valid for both genders. Methods: A sample of 100 individuals (50 women and 50 men) from 18 to 70 years old was analyzed in this observational study. A bioimpedance analysis was performed along with anthropometric determinations according to ISAK standards. Results: The percentage of arm fat mass estimated by bioimpedance strongly and positively correlated with the triceps and biceps skin folds, the arm fat area, and its percentage of fat area, in both sexes. In women, the percentage of arm fat mass also correlated with body mass index, arm circumference, and arm muscle area. Conclusion: Through a linear regression formula applicable to both sexes, the percentage of arm fat can be estimated from three anthropometric measurements.
