Abstract
The objectives of this study were: (1) to validate the SUVIMAX iconographic method against the weighed diet record method to assess food and nutrient intake in obese and post-obese adolescents, and (2) to determine the effects of dietetic education on the precision of this method. Energy and nutrient intakes were determined by both methods in 26 institutionalized obese adolescents over 7-day periods before the beginning and at the end of a weight-reduction programme, and 4 months later. The mean food, energy, carbohydrate, protein and lipid intakes as assessed by the two methods were not significantly different but the limits of agreement between the two methods were high. Obese and post-obese adolescents underestimated intake of their favourite meals (pasta, fried potatoes) but often overvalued intake of vegetables, milk and hard cheese. The SUVIMAX iconographic method is, therefore, a reliable method to assess energy and nutrient intakes of obese and post-obese adolescents in epidemiological studies, but is inappropriate for assessing individuals. In addition, dietetic education resulted in a 50% decrease in the mean difference, and in the inter-individual differences in energy intake between the two methods.
