Mediation models of external synchronizerson body weight variation. Body weight variation (BWV) as the dependent variable, Δ sleep duration, Δ sedentarism, Δ screen exposure time as independent variables. Δ was calculated by subtracting the variables from the thirteenth week to the first week of confinement. The straight arrows represent the correlation between variables of interest; the curved arrows denote the covariance among the three represented external synchronizers. The beta coefficients are shown in italic letter while beta coefficients of the adjusted model are shown in bold letter. Cov. = Covariance. BMI = Body Mass Index. Δ = Delta. ∗∗∗p < 0.001, ∗p < 0.05.
