OBJECTIVE: To study the neck circumference (NC) cut-off points for identifying excess body weight levels in adolescents from age between 12-17 years METHODS: Cross-sectional study was conducted using the data from a Brazilian multicentric project called Study of Cardiovascular Risks in Adolescents - ERICA, which included adolescents with age between 12-17 years' residents in two Brazilian cities from the Northeast part of Brazil. Anthropometric measurements and blood pressure data were collected from the adolescent's sample. The mean average in between the adolescents' groups was compared using the Mann-Whitney. The correlation was estimated by Spearman correlation coefficient to evaluate the association between the NC and other anthropometric variables like age, waist circumference (WC), body mass index (BMI) and blood pressure. The ROC curve was used to analyze the predictive validation of NC as well as to determine the cut-off point of overweight and obesity identification among the adolescents RESULTS: This study comprised 1474 adolescents with a mean age of 14.59 ± 1.57 years, in which 55.3% were female. It was found a positive correlation between NC and WC; NC and BMI. The cutoff point for overweight according to the NC for male adolescents aged 12 to 14 years was equivalent to 34.1 cm and for females 32.05 cm. The adolescent male aged 15 to 17 years group the cutoff point was 36.85 cm and for women 32,95 cm. The cutoffs points for obesity according to the NC for male adolescents aged 12 to 14 years was 34.9 cm and for females 33.85 cm. In the age group 15-17 years, the cutoff point for obesity for males was 38.4 cm and for females 35.85 cm CONCLUSIONS: The neck circumference represented significant correlation among waist circumference and body mass index well stablished indicators of adiposity and can identify adolescents with high body mass index
