title: Health-related quality of life in obesity: the role of eating behaviour.
abstract: A poor health-related quality of life (HRQL) has been repeatedly documented in obesity. Overweight per se and associated diseases affect physical fitness, whereas mental well-being depends on social, cultural and behavioural components. Very few studies are available on HRQL in obese persons in relation to eating behaviour. We measured HRQL by means of Short-Form-36 questionnaire in 183 obese subjects, seeking specific treatment at a University-based weight management center. Only half had a Body Mass Index exceeding 35 kg/m2. Data were compared to age- and gender-adjusted normative values of the Italian population (2031 subjects). The Binge Eating Scale (BES) and the Three-Factor Eating Questionnaire (TFEQ) were used to assess eating behaviour. Most domains of HRQL were impaired in obese subjects, more severely in younger subjects and in females. The severity of overweight progressively affected physical fitness, but had a minor effect on mental status. In over 50% of subjects, BES and TFEQ identified a binge eating pattern, more frequently in females. A positive BES, as well as lower restriction, higher disinhibition and hunger values at TFEQ, identified subjects with poorer HRQL. Logistic regression analysis identified in a positive BES the variable more closely associated with low scores in mental domains of perceived HRQL. Waist-to-hip ratio, degree of obesity, osteoarticular and respiratory diseases, but also positive BES, were selected as variables more closely associated with poor physical fitness. HRQL is variably impaired in obese persons seeking treatment for their disease, mainly in patients with binge eating. Treatment of binge eating may be as important as any weight-reducing intervention for the overall well-being of the majority of obese persons.
