Abstract

The present study aimed to examine associations between body image and under-reportingin female Japanese university students enrolled in a nutrition degree program. A total of 100participants (aged 18–29 years) completed (1) a self-administered questionnaire including theBen-Tovim Walker Body Attitudes Questionnaire (BAQ), (2) a dietary assessment using a brief-typeself-administered diet history questionnaire (BDHQ), (3) a physical activity assessment usingBouchard’s Physical Activity Record (BAR) and a tri-axial accelerometer, (4) detailed anthropometry,and (5) body composition assessment. Based on the energy intake to basal metabolic rate ratio(EI:BMR) and using a cut-off point of 1.35, 67% of participants were considered under-reporters(URs). While there was no between-group difference in BMI, URs had significantly (p < 0.05) greaterpercentage body fat (%BF) and trunk fat (%TF) compared with non-URs. Regression analysesindicated accuracy of body perception and a discrepancy between current and ideal weight wereassociated with EI:BMR, whereas the salience subscale of the BAQ was associated with reported EI.The study raises concerns regarding the validity of EI reported from young Japanese females as theyare known to have a strong preoccupation with thinness, even with an acceptable BMI and healthand nutritional knowledge.
