cFrom food questionnaire.
dScored from food questionnaire questions on frequency of intake of takeaway or fast food; sugary cereals; potato chips or other salty foods; sweets; and cakes, doughnuts, sweet cookies, or muffins. Responses of never or rarely, 1 to 3 times per month, 1 to 2 times per week, 3 to 4 times per week, 5 to 6 times per week, once per day, and 2 or more times per day were coded as 1-6, respectively, and summed to obtain a discretionary food score.
eSelf-efficacy questionnaire.
fChild feeding questionnaire.
gParent modeling questionnaire.
hAccelerometer measures.
iFrom sleep questionnaire.
jFrom screen time questionnaire.
