Impact of interviewer 's body mass index on underreporting energy intake in overweight and obese women . OBJECTIVE To determine if overweight and obese women provide more accurate reports of their energy intake by 1 ) in-person recall with an obese interviewer , 2 ) in-person recall with a lean interviewer , or 3 ) telephone recall with an unknown interviewer . RESEARCH METHODS AND PROCEDURES Eighty-eight overweight and obese women participated in this study . Subjects completed one telephone-administered multiple-pass 24-hour recall ( MP24R ) with an unknown interviewer and were then randomly assigned to an in-person MP24R with either a lean or obese interviewer to gather reported energy intake ( rEI ) . Basal metabolic rate ( BMR ) was measured using a Deltrac monitor , and physical activity ( EEPA ) was estimated using a Caltrac accelerometer . Therefore , estimated energy expenditure was determined by : estTEE = ( BMR + EEPA ) x 1.10 . RESULTS No significant differences were found between the two in-person interview modes for subject age , weight , body mass index , percentage of body fat , total energy expenditure , rEI , and misreporting of energy intake . In-person recall data were combined for comparison with the telephone recalls . No significant difference was found between the in-person and telephone recalls for rEI and misreporting . Mean reported energy intake was significantly lower than estimated total energy expenditure for the telephone recalls and combined ( lean and obese modes ) in-person recalls . CONCLUSIONS This study found that interviewer body mass index had no impact on self-reported energy intake during an in-person MP24R , and that telephone recall data were comparable with in-person recalls . Underreporting was a widespread problem ( approximately 26 % ) for all modes in this sample .
