Normal weight obesity (NWO) represents individuals with normal body mass index (BMI) and excess adiposity. Previous literature has established associations between NWO and poor cardiometabolic health, however, literature examining NWO among adolescents is limited. PURPOSE: To determine the prevalence of NWO among adolescents in Idaho and compare nutritional behaviors between those characterized as normal weight lean (NWL), NWO, and obese (OB). METHODS: Participants (n=140) aged 14-19 years were recruited from high schools in Idaho. After completing an informed consent and parental assent, high school visits were scheduled. Height and weight, body composition (BIA), and dietary recall were assessed. Participants were grouped (NWL, NWO, OB) using BMI (World Health Organization BMI adolescent percentiles) and body fat (BF; %). A one-way ANOVA was used to assess differences in diet among NWL, NWO, and OB groups. Significant findings were further analyzed with Tukey’s post hoc test. RESULTS: Of the adolescents sampled, 11% were characterized as NWO. Females (n=70) had a significantly higher NWO prevalence rate (21%) compared to males (n=70; 0.01%). NWO had a significantly lower (22.8 ± 1.75) BMI compared to OB (32.5 ± 4.49; p
