Child fruit and vegetable consumption
Children’s FV consumption was measured using items
from the US School Physical Activity and Nutrition Survey
[15]. Parents were asked ‘how many servings of fruit’
and ‘how many servings of vegetables’ does your child
eat on a typical day. To help parents estimate the number
of servings, pictures and standard definitions of fruit
and vegetable serving sizes were included in the survey
(e.g., one medium piece of fresh fruit, one small bowl of
green salad, ½ cup/4 oz of fresh or cooked vegetables).
Response categories were zero, one, two, three and four
or more servings per day. Responses to both items were
summed to provide an index of daily FV consumption.
The items have evidence of acceptable test-retest reliability
(r = 0.73-0.79) and validity compared to a 24-h
recall (r = 0.53-0.57) [16].
