In West Africa, the multiple-day weighed record is the most widely used technique for measuring children's food intakes.
The children's eating behavior might be disrupted by the frequent weighings and the presence of a field-worker in the home.
We explored the possibility of such an « instrument effect » in a 7-d food survey of 70 Senegalese children aged 10-13 mo.
Energy intakes decreased significantly during the food survey (P<0.0001).
The decrease affected both daytime breast milk intake (8%) and solid food intakes (15%). The children's weight gain also decreased from a presurvey value of 6.9 to 2.1 g.kg-1.wk-1, indicating that their intakes during the food survey were lower than their usual intakes.
The food-survey methodology was responsible for this « instrument effect ».
