The objectives of present study were (i) to test if there is an association and (ii) di f f er en ce between the level of physical act ivity (LPA) and body composition of adolescents from public and private schools. A total of 84 adolescents (female: n = 52, 61.9% and males: n = 32, 38.1%), with a mean age o f 16.4 ± 0.8 years (female = 16.5 ± 0, 8 years and male 16.4 ± 0.8 years) regularly enrolled in a publ ic an d private school in the municipality of Fortaleza/CE. NAF was quant ified through the ap p licat ion o f t he physical act ivity quest ionnaire for adolescents. Subsequent ly data were obtained (body mass and height) to calculate the body mass index (BMI). The percentage of body fat (% BF) was est imated according to sex . The Pearson correlation test was used to verify association between the variables. For comparison between public and private school students, we used the differences of standardized means, co nfiden ce in terv al (90%), effect size and probability of differences. We did not find significant associations between LPA and BMI (r = 0.033 to 0.214; p> 0.05) and LPA and % BF (r = - 0.19 to 0.310; p> 0.05). There wer e n o substant ial differences between public and private school students for LPA and body compo s i t ion. The lack of st rong association between NAF and body composition points to the multifactorial character t hat per passes the relationship between these two variables in the young population. Addit ionally, studying in a public or private school does not seem to affect LPA and the body composition of adolescents
