^aSignificant at P<.05.

^bCalculated from 24-hour diet recall using Easy Diet Diary/Foodworks.

^cFrom Food Questionnaire.

^dScored from food questionnaire questions on the 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 to 6, respectively, and summed to obtain a discretionary food score.

^eSelf-efficacy questionnaire.

^fItalicized text: statistically significant result.

^gChild feeding questionnaire.

^hParent modeling questionnaire.

ⁱAccelerometer measures.

^jFrom sleep questionnaire.

^kFrom screen time questionnaire.
