Overweight and Obese Children's Ability to Report Energy Intake Using Digital Camera Food Records during a 2-Year Study

Table 2

Assessed energy intake (EI) from estimated food records aided by digital camera and total energy expenditure (TEE) registered with SenseWear Armband, of children on 7 occasions during 2 years. Data are presented as mean (SD), [95% CI], correlation coefficient, or percentage proportion, and the difference between EI and TEE was analyzed using the one sample t-test and Spearman’s correlation.
