BMI was the outcome (direct measurement of height and body mass) and exposures were the excessive time in front of the TV (> 2h/day), daily consumption of UPFs and PA. Quantile regression was used to test associations and interactions. Excessive time in front of the TV was associated with higher BMI values(e.g., 25th percentile = 0.060 kg/m² versus 95th percentile = 0.891 kg/m², p
