* Models were adjusted for items from unadjusted models in Table 3 if P<0.25 (maternal analyses: child’s sex, child’s BMI z-score, maternal age at birth, maternal ethnicity, maternal pregnancy BMI, maternal screen time, maternal depression at baseline; partner analyses: child’s sex, child’s BMI z-score, partner ethnicity, paternal BMI at 24 months), with additional adjustment for POI study group, and household deprivation category and maternal parity (variables used for the stratified randomization of the POI participants into groups).
† Quantile regression (ß)—predicted change to median minutes of children’s television viewing per day for every unit change in the parenting style variable.
