Internal and external predictors of fruit and vegetable consumption in children

[摘要] This thesis explored internal and external predictors of fruit and vegetable intake in children of different age groups. The first sample were toddlers between 2-3 years old and the second sample were children between 5-9 years old. Intake of fruit was analysed separately from intake of vegetables, and subgroups of fruit and vegetables with strong sensory properties were also analysed separately. The results showed that in the older sample lifetime exposure to variety of different fruit and vegetables was positively associated with quantity and diversity of fruit and vegetables consumed. In toddlers, liking of fruit and vegetables was not directly linked to their intake. In children of less controlling mothers fruit liking was positively associated with fruit intake and children of the more controlling mothers ate fruit independent of fruit liking. Past history of middle ear infections may affect adiposity and fruit and vegetable intake. Finally, individual levels of sensitivity to sweet taste may affect adiposity and intake of cruciferous vegetables and non-astringent fruit in school-age children. Parental intake was the strongest predictor of intake in both age groups. The results of this thesis show that fruit and vegetables have different predictors of intake and need to be considered separately.
