Early care and education (ECE) centers that require lunch brought from home provide an uncluttered view of parent-child dietary interactions in early childhood. Children's eating from parent-provided bag lunches was observed at 30 ECE centers in Texas, with 15 randomly assigned to the Lunch is in the Bag intervention to improve the lunch meal and 15 to a wait-list control condition. Study participants were parent and child aged 3–5 years (N = 633 dyads). Data were collected at baseline (pre-intervention) and follow-ups at weeks 6 (post-intervention), 22 (pre-booster), and 28 (post-booster). Changes effected in the children's lunch eating—e.g., increase of 14 percent in prevalence of children eating vegetables (SE = 5, P = 0.0063)—reciprocated changes in parent lunch-packing. Irrespective of intervention, however, the children consumed one-half to two-thirds of the amounts of whatever foods the parents packed, and the eat-to-pack ratio did not change across time. Thus, children's lunch eating at the ECE centers appeared to be regulated by perceptual cues of food availability rather than food preferences or internal cues of hunger and satiety.
