Restrained eating, disinhibition and hunger were measured on the Three-Factor Eating Questionnaire compiled by Stunkard and Messick. The evaluated subjects were 300 adults (39 men and 261 women) and 45 obese individuals who participated in a behavioral weight loss program at a public health center. The data from 300 adults showed that factor 2, "disinhibition", was most strongly correlated with body weight, Body Mass Index, and % overweight. The features of eating behaviro differed by sex, age and Body Mass Index. Subjects whose questionnaire scores were more than 2 standard deviations from the mean were highly suspected of abonrmal eating and were screened. They were 11% of the 300 adults and adults and 36% of the 45 obese participants. Factor 1, "cognitive restraint of eating", was inversely correlated with their weight loss by a behavioral intervention. From these results, we conclude that the Three-Factor Eating Questionnaire is useful in Japanese subjects, and suggest that it can be used to screen 'for abnormal eating behavior such as bulimia and anorexia and predict the effects of weight loss treatment.
