The aim of was to assess the validity of reported energy intake (EI) in overweight and obese children participating in a diet history interview (DHI). The validation was made by comparison with total energy expenditure (TEE) measured with a portable device called SenseWear Pro2 Armband (SWA) version 5.1, which measures acceleration and body heat in free-living conditions. In total, 85 subjects (41 girls, 44 boys) aged 8-12 years who were overweight or obese according to age and sex specific body mass index ≥25 kg/m2 participated. The children were interviewed together with their parent/s about food intake during the preceding two weeks. Portion sizes were described with the help of household measurements and food-portion photographs. The reported food intake was entered into the dietary analysis program Dietist XP version 3.0 to calculate the EI. TEE was measured with SWA during four days (two weekdays and two weekend days) during the same time period covered by the DHI interview. The mean EIrep/BMR was 1.42 compared with the physical activity level (PAL=TEEmeas /BMR) which was 1.68. EI was underreported significantly by 1.73 ± 2.63 MJ/day (95 % CI: 1.16, 2.30). A statistically significant difference in underreporting was found between the 64 children with overweight and the 21 children with obesity. The EI of overweight children was underreported by 11 % compared with the EI of obese children who was underreported by 22 % (95% CIs: 0.55, 3.08). However, there were no significant differences in underestimation of EI with respect to gender. In conclusion, when using a DHI method, the EI of overweight and obese children was underreported by 14 %. Furthermore, the EI of obese children was underreported twice as much as the EI of overweight children.
