Effect of fast-food environments on children's eating behaviour: A random effect within between analysis within the Generation R Study

Abstract

Background: Focussing on appetitive traits associated with obesity, this study aimed to estimate the association between the fast-food environment and satiety responsiveness, enjoyment of food and food responsiveness. Methods: We used data from the Generation R Study. We included 2008 children with repeated measurements at the age of 4–10 years old. Three eating behaviour subscales from the Child Eating Behaviour Questionnaire (CEBQ) were used as outcomes. Geographical Information System data were used to map individual-level exposure to fast-food outlets within 400 m from home. Random Effect Within Between (REWB) models were used to derive estimates. We tested for moderation of the associations with parental restriction at baseline using the parent-reported Child Feeding Questionnaire (CFQ). Results: We did not find evidence of between-associations of fast-food exposure and eating behaviour subscales. Considering within-associations, an increase in absolute fast-food exposure was associated with a significant marginal increase in satiety responsiveness (β: 0.02 [95% confidence interval: 0.00–0.03]). No moderation by parental restriction was found. Conclusions: In environments with ubiquitous fast-food outlets, an increased exposure to fast-food outlets does not seem to have a substantial impact on eating behaviour. Further research is needed to better understand how fast-food exposure contributes to overweight.
