Sommaire de l'article

BACKGROUND: Monitoring the dietary intake of the French population requires the implementation and regular renewal of representative national survey. As these surveys can use different methodologies (food frequency questionnaire, 24 hour recall, 3 or 7-day dietary record…), it seems useful to check whether they supply similar results. The aim of this study is to determine whether two representative national surveys with different methodologies can be used alternately to monitor changes in food consumption of the French population.

METHOD: Percentages of consumers aged 15-75 were compared between two national food surveys (Health Nutrition Barometer 2002 and INCA 1 1998-99) with respect to five food frequency recommendations of the French National Nutrition and Health Program.

RESULTS: The same public health priorities were found in both surveys: the food groups were graded according to the same hierarchy of adequate food intake prevalences (ascending: fruits and vegetables, dairy products, fish, starchy foods and meat-fish-egg products). On the other hand, significant statistical different elements were pointed out in a few food groups which may be explained by methodological patterns. Definitions of portions and food groups, survey duration and seasons are indeed important parameters to be considered when comparing surveys.

CONCLUSION: The results show the need to elaborate standardized methods for comparison of food consumption surveys, which can be useful for the evaluation of the national nutritional recommendations. The methodological limitations described in this study also indicate that the quantitative description of food intake trends should improve when established by the results of the same regularly repeated survey.
