Peer education appears to be an effective means of achieving an increase in fruit and vegetable intake among lower socioeconomic, multicultural adult employees.
Energy underreporting occurs in 2% to 85% and overreporting in 1% to 39% of various populations. Efforts are needed to understand the psychosocial and behavioral characteristics associated with misreporting to help improve the accuracy of dietary selfreporting. Past research suggests that higher social desirability and greater eating restraint are key factors influencing misreporting, while a history of dieting and being overweight are more moderately associated. Eating disinhibition, body image, depression, anxiety, and fear of negative evaluation may be related to energy misreporting, but evidence is insufficient. This review will provide a detailed discussion of the published associations among psychosocial and behavioral characteristics and energy misreporting.
Objective: Assess the association between reporting bias of dietary energy intake and the behavioral and psychological pro®les in women. Design: At baseline a series of questionnaires were administered to 37 women, (the Marlowe-Crowne Social Desirability Scale, Weinberger Adjustment Inventory (WAI), the Eating Disorder Inventory (EDI), the Restraint Scale and Sorensen-Stunkard's silhouettes). Subjects received training on how to record dietary records. Subjects recorded three days of dietary records to measure energy intake (EI) during a study to determine total energy expenditure (TEE) using doubly labeled water. Reporting accuracy (RA EIaTEE 6 100) was determined for each subject. Statistical analysis of the data used a mixed effects model accounting for within subject variability to determine if the psychological scores were associated with reporting accuracy. Setting and subject: Women were recruited with local advertisements in Tucson, Arizona. The women had a mean ( AE 1 s.d.) age of 43.6 AE 9.3 yrs, body mass index (BMI) of 28.7 AE 8.5 kgam 2 and total body fat (%TBF) of 31.9 AE 7.3%. Results: Age and %TBF were signi®cantly and inversely associated with RA. Furthermore, Social Desirability was negatively associated with RA. Body dissatisfaction and associating a smaller body size than one's own as being more healthy were also associated with a lower RA. Conclusions: These results suggest that Social Desirability and self image of body shape are associated with RA. Modi®cations in subject training may reduce the effect of these factors on RA.
