Abstract

BackgroundFruit and vegetable FV intake in children in the Netherlands is much lower than recommended. Recurrent appraisal of intake levels is important for detecting changes in intake over time and to inform future interventions and policies. The aim of the present study was to investigate differences in fruit and vegetable intake, and whether these could be explained by differences in potential determinants of FV intake in 11-year-old Dutch schoolchildren, by comparing two school samples assessed in 2003 and 2009.

MethodsFor 1105 children of the Pro Children study in 2003 and 577 children of the Pro Greens study in 2009 complete data on intake and behavioural determinants were available. The self-administered questionnaire included questions on children-s ethnicity, usual fruit and vegetable intake, mother-s educational level, and important potential determinants of fruit and vegetable intake.

Multiple regression analysis was applied to test for differences in intake and determinants between study samples. Mediation analyses were used to investigate whether the potential mediators explained the differences in intake between the two samples.

ResultsIn 2009, more children complied with the World Health Organization recommendation of 400 g fruit and vegetables per day 17.0% than in 2003 11.8%, p = 0.004. Fruit consumption was significantly higher in the sample of 2009 than in the sample of 2003 difference = 23.8 95%CI: 8.1; 39.5 grams-day. This difference was mainly explained by a difference in the parental demand regarding their child-s intake 23.6%, followed by the child-s knowledge of the fruit recommendation 14.2% and parental facilitation of consumption 18.5%. Vegetable intake was lower in the 2009 sample than in the 2003 sample 12.3 95%CI -21.0; -3.6. This difference could not be explained by the assessed mediators.

ConclusionsThe findings indicate that fruit intake among 11-year-olds improved somewhat between 2003 and 2009. Vegetable intake, however, appears to have declined somewhat between 2003 and 2009. Since a better knowledge of the recommendation, parental demand and facilitation explained most of the observed fruit consumption difference, future interventions may specifically address these potential mediators. Further, the provision of vegetables in the school setting should be considered in order to increase children-s vegetable intake.
