expenditure (TEE) measured by doubly labeled water in physically active lean and sedentary obese young women,

and to compare reporting accuracy between the two subject groups.Design: A cross-sectional study in which dietary intakes of women trained in diet-recording procedures were

analyzed using the Minnesota Nutrition Data System (NDS; versions 2.4=6A=21, 2.6=6A=23 and 2.6=8.A=23) and

Nutritionist III (N3; version 7.0) software. Reporting accuracy was determined by comparison of average TEI

assessed by an 8 day estimated diet record with average TEE for the same period.Results: Reported TEI differed from TEE for both groups irrespective of nutrient database (P < 0.01). Measured

TEE was 11.10[C6] 2.54 and 11.96[C6] 1.21 MJ for lean and obese subjects, respectively. Reported TEI, using either

database, did not differ between groups. For lean women, TEI calculated by NDS was 7.66[C6] 1.73 MJ and by N3

was 8.44[C6] 1.59 MJ. Corresponding TEI for obese women were 7.46[C6] 2.17 MJ from NDS and 7.34[C6] 2.27 MJ from

N3. Lean women under-reported by 23% (N3) and 30% (NDS), and obese women under-reported by 39% (N3)

and 38% (NDS). Regardless of database, lean women reported higher carbohydrate intakes, and obese women

reported higher total fat and individual fatty acid intakes. Higher energy intakes from mono- and polyunsaturated

fatty acids were estimated by NDS than by N3 in both groups of women (P [C20] 0.05).Conclusions: Both physically active lean and sedentary obese women under-reported TEI regardless of database,

although the magnitude of under-reporting may be influenced by the database for the lean women.
