BACKGROUNG: The World Health Organization (WHO) recommends the use of the body mass index (BMI) as a cost-effective method to assess the nutritional status at the population level. The increase of BMI is linked to a higher risk of other chronic non-communicable diseases (NCDs), particularly hypertension, type 2 diabetes mellitus (T2DM), dyslipidemias, and some types of cancer. The prevalence of obesity has increased worldwide, and this condition has dramatically affected children and adolescents. Obesity at a young age increases the chances of severe obesity and its complications in adultsOBJECTIVE: This study aimed to establish cut-off points for body fat percentage in male and female adolescents aged 16 to 18 years using bioelectrical impedance (InBody 570®METHODS: Gender specific tables were proposed based on the percentiles 3, 5, 10, 15, 25, 50, 75, 85, 95 and 97. A total of 546 adolescents were includedRESULTS: The body fat percentage cut-off points for the male group were: P3 = 6.0-7.0%; P5 = 7.1-8.9%; P10 = 9.0-9.8%; P15 = 9.9-11.7%; P25 = 11.8-15.5%; P50 = 15.6-21.9%; P75 = 22.0-27.8%; P85 = 27.9-36.0%; P95 = 36.1-38.0% and P97 ≥ 38.1%. For females, the cut-off points were: P3 = 9.5-10.0%; P5 = 10.1-11.0%; P10 = 11.1-11.8%; P15 = 11.9-14.0%; P25 = 14.1-19.0%; P50 = 19.1-27.1%; P75 = 27.2-29.0%; P85 = 29.1-39.9%; P95 = 40.0-51.0% and P97 ≥ 51.0%CONCLUSION: The establishment of cut-off points for body fat percentage may improve the clinical assessment and management of overweight and obese adolescents
