Des difficultes de l'approche de la consommation alimentaire dans les hopitaux de Tunis

ABSTRACT

Dietary intake analysis of a patient in a hospital could help effectively in researching of alimentary risk factors and in establishing adequate care. Then, data obtained by dieteticians must be precise. The purpose of the present study was to identify the sufficient conditions to cary out the recall diet assessment of patients with realiability and reproductibility. A preliminary questionnaire tested was proposed to fourty dieteticians working in the seven main hospital of Tunis. We have approched methods and means used to hold aquiry and to estimate the divergence between dieteticians in the measure of energy intake from a meal initialy established. Our results show that half of dieteticians make investigation daily only three of them use logicials to calculate amounts of nutrients intake. The majority of dieteticians use nine different alimentary composition tables. The analysis of meal proposed showed significant differences in the estimation of energy intake [1789 to 3086] and in its repartition between lipids [31 to 55%], carbohydrates [33 to 71%] and proteins [13 to 93%]. The results strongly confirm that the evaluation of dietary intake is a complex undertaking because of its dependance on methods and means used by investigators. Making these techniques uniform is a necessary condition to obtain reproductible results:
