Aim:
To evaluate the eating behaviour in normal-weight, overweight, and obese women seeking participation in a diet-based programme of weight reduction or achievement of ideal body weight.
Methods:
Thirty-seven obese, 42 overweight, and 14 normal-weight subjects, seen at an Italian university outpatient clinic, were asked to complete the Stunkard and Messick three-factor eating questionnaire (TFEQ). The TFEQ is designed to evaluate three different factors in eating behaviour: restraint, disinhibition, and hunger. Forty-eight mothers of children attending public primary schools (25 normal weight and 23 overweight) served as controls.
Results:
Significantly altered scores of cognitive restraint were observed both in normal-weight and in overweight subjects of the outpatient clinic as compared with normal-weight and overweight control women. Outpatient clinic overweight women scored significantly higher in terms of disinhibition as compared with overweight control subjects. Among outpatient clinic subjects, overweight women showed higher scores of disinhibition but similar values of cognitive restraint as compared with outpatient clinic normal-weight subjects. In obese patients, the scores of disinhibition and hunger were higher than those observed in outpatient clinic normal-weight subjects, whereas values of cognitive restraint were significantly lower. As compared with outpatient clinic overweight women, obese subjects showed significantly lower values of cognitive restraint.
Conclusions:
Alterations in TFEQ results are a frequent feature in subjects seeking participation in programmes of weight reduction or ideal body weight achievement. This may reflect a possible impairment in eating behaviour.
