【 摘 要 】

2 h/day), daily consumption of UPFs and PA. Quantile regression was used to test associations and interactions. Excessive screen time was associated with higher BMI values (e.g., 25th percentile =0.060 kg/m² versus 95th percentile =0.891 kg/m², p<0.001). After adjusting for PA, the association remained, however, attenuated. The inclusion of UPFs in the model potentiated the association (e.g., 25th percentile =0.062 kg/m² versus 95th percentile =0.956 kg/m², p<0.001). Excessive screen time was associated with BMI percentiles, irrespective of PA - the absence of PA and the presence of UPF consumption affect the upper BMI percentiles more. Actions to reduce excessive TV viewing time, consumption of UPFs and promoting PA are essential to positively impact BMI and its reflexes on the health of Brazilian adolescents.
