Fruit and vegetable intake

Change in fruit and vegetable intake from baseline to 4 weeks as measured by self-report via the NCI Fruit and Vegetable Intake Screener (from the Eating at America's Table Study). Scale Range: Frequency of intake (fruit, vegetable) - Never (minimum) to 5+ times per day (maximum); and Portion of fruit or vegetable (cup equivalents based on dietary guidelines). To score, 1) express each reported frequency as a daily average by standardizing the midpoint of each frequency category to the number of times per day; 2) assign fruit and vegetable servings from dietary guidelines to each portion size category; and 3) compute the average daily fruit and vegetable servings for each food group by multiplying the average daily frequency (from #1) by the number of servings for the portion size (as determined in #2). To estimate the total daily number of servings, sum across all food groups (i.e., fruit and vegetable subgroups).

Time frame: Baseline and 4 weeks

Beverage intake

Change in beverage intake intake from baseline to 4 weeks as measured by self-report via the (Beverage Intake Questionnaire-15 (BEVQ-15). Scale Range: Frequency of intake (of beverage option) - Never (minimum) to 3+ times per day (maximum); Consumption (of each beverage option)- Less than 6 fl. oz. (minimum) to more than 20 fl. oz (maximum). To score the instrument, frequency ("How often") is converted to the unit of times per day, then multiplied by the amount consumed ("How much each time") to provide average daily beverage consumption in fl oz. To quantify total SSB consumption, beverage categories containing added sugars were summed (sweetened juice beverages/drinks, regular soft drinks, sweet tea, sweetened coffee, energy drinks, mixed alcoholic drinks, meal replacement beverages).
