Estimating energy intake (EI) of a child by using a diet history interview (DHI) method may be a challenge because of difficulties for the child to remember what has been eaten as well as to report portion sizes. The aim of this research was to validate reported EI from a DHI in children classified as overweight or obese by comparing the reported EI to total energy expenditure (TEE) measured by two objective measures. Eighty-five 10.5 ± 1.1 y old overweight and obese children, with help from one or two parents, reported their EI two weeks retrospectively in a DHI. Reported EI was compared with TEE, as measured by SenseWear Armaband (n=85) and the doubly-labelled water (DLW) method (n=21), during the same period as the DHI. Reported EI was under-estimated by 14 % when validated against both the armband and DLW method. Under-estimation did not differ between boys and girls. However, the EI of obese children was under-estimated by 22 %, which is twice the rate as for the overweight children (95% CI: 0.55, 3.08). Under-estimated EI was negatively correlated with body mass index (BMI) (r=-0.38, P= <0.01) as well as age (r=-0.21, P=0.05). EI is under-estimated to a higher extent among children with higher BMI and higher age when using a DHI method. The findings show the importance of validating dietary intake of children in general and in overweight and obese children in particular.
