• Objective: To examine factors associated with reporting error for total energy intake (TEI), which was estimated from food records and by doubly labeled water (DLW) method in female athletes.Methods: Our study comprised 38 female athletes (middle and long-distance runners, swimmers, rhythmic gymnasts and lacrosse players). Calculated total energy expenditure (cTEE) was calculated from total energy expenditure (TEE), which was assessed by the DLW method and changes in body weight during the study period. TEI was assessed using food weight records from the TEE assessment period.Results: cTEE and TEI were, respectively, 2,673±922 kcal/day and 2,151±434 kcal/day for runners, 2,923±749 kcal/day and 2,455±297 kcal/day for swimmers, 3,276±497 kcal/day and 1,852±314 kcal/day for gymnasts, and 2,628±701 kcal/day and 2,329±407 kcal/day for lacrosse players. Reporting errors were −13.6±24.1%, −13.3±14.3%, −42.0±15.3%, and −2.8±38.3% for runners, swimmers, gymnasts, and lacrosse players, respectively. Reporting error was significantly greater in gymnasts than in lacrosse players. However, no sportive attributes in body composition or dietary intake among four groups were observed. Subjects with high precision TEI assessment had lower TEE, a lower proportion of energy intake from fat, higher intake of confectioneries, higher number of meals, and a greater proportion of energy intake from carbohydrates than subjects with under-reporting in TEI assessment. Low TEE was significantly and independently associated with high precision in TEI assessment.Conclusions: In female athletes, TEI reporting error was related to TEE, type of sporting activity, confectionery and macronutrient intake, and number of meals. Further research is needed to assess psychological and social factors that may contribute to TEI reporting error.
