The dependent variables have been calculated as response = 0, no response = 1; ^aReference category; ^bThe category of "non-standard families" comprises both "single parent" and "other" families. The CHIP-AE domains have been introduced as categorical variables. Higher score signifies better health. Each model is adjusted for the rest of the variables in the table.
