Objectives: To assess the validity of a four day weighed food record in the measurement of energy intake in female classical ballet dancers.
Design: Twelve classical ballet dancers volunteered to take part in this study.
Setting: Queensland University of Technology.
Subjects: Twelve classical ballet dancers. Data collected from one subject was not used due to poor compliance with the requirements of the study.
Interventions: Measurements of energy intake via a four day weighed record and total energy expenditure via the doubly labelled water technique.
Results: There was a mean bias to under-reporting energy intake of 667 kcal/day or 21% of real intake.
Conclusions: Results of dietary data obtained via a four day weighed intake should be viewed with caution in the light of the evidence of major under-reporting in this cohort.
