INTRODUCTION: Metabolic alterations commonly found in obese individuals have also been shown by non-obese according to their body mass index. Therefore, evidence has shown the development of changes in body composition and anthropometric measurements in these individuals. However, few studies have evaluated anthropometry and body composition in healthy adults in the Brazilian population. OBJECTIVE: To assess body adiposity in healthy adults and determine the discriminatory power of anthropometric indices in identifying body fat (BF) excess. METHODS: The cross sectional, quantitative research will be developed at the Clinical Research Unit of the Walter Cantídio University Hospital-UFC/EBSERH. The sample was for convenience, composed of employees and students of the hospital complex. Patients were interviewed and evaluated at the institution, using a semi-structured questionnaire containing identification data, socioeconomic status, disease history, anthropometric parameters such as body mass index (BMI), waist circumference (WC), neck circumference (NC), ratio waist/height (WHR) and waist/hip ratio (WHR) and body composition by double emission X-ray densitometry (DEXA). Healthy adults with a BMI between 18.5 and 29.9 kg/m² were included. Data were collected using Redcap and analyzed by the Jamovi statistical program. Excess body fat was considered values above 25% and 30% for men and women, respectively. RESULTS: 338 people participated in the study. The mean age of the individuals evaluated was 28.5 years (9.35), 60.2% (n=192) were female. The mean BMI was 24.0 (2.76) kg/m2 indicative of normal weight, with no significant difference between men and women. However, the %BF was above the cut-off points in most of the sample (66%; n=223), with an average of 24.5% (5.93) and 36.2% (5.83) for men and women, with significant differences (p<0.001). CONCLUSION: A high prevalence of normal-weight obesity was observed in young adults.
