ABSTRACT
OBJECTIVE: To test the impact of body image on quality of life in overweight and obese people; to evaluate longitudinally the relationship between changes in body image, anthropometrical measurements and quality of life. DESIGN: A cross-sectional study and a longitudinal study in a sub-sample after 6 months. SUBJECTS: 308 women in the cross-sectional study and 56 in the longitudinal study, aged 21-65, with body mass index (BMI) > 25 kg/m2 and selected from people who had been sought treatment for overweight in our Institute from 1998 to 2001. MEASUREMENTS: Body weight, body height, waist and hip circumferences. The ORWELL 97 questionnaire to evaluate the obesity related quality of life (ORQL) and the BUT questionnaire to assess the body image (BI) were used. RESULTS: The BUT score was the variable that explained the greatest amount of variance of ORWELL 97 both in cross-sectional and longitudinal studies. Despite no significant differences in athropometrical variables were found between subjects who dropped out and those who did not, psychometrical scores were significantly better in patients still in treatment in follow-up. CONCLUSION: BI is related to subjective ORQL independently of anthropometrical measurements both at baseline and after treatment. Better psychometrical scores in people still in treatment after 6 months suggest that BI could be considered one of the variables which influence compliance to the treatment program, this fact needs more investigations and could be of interest in obesity treatment outcome studies.

Alzheimer s disease is the most frequent cause of dementia in elderly people and it is one of the leading causes of death among older individuals. Weight loss is a frequent clinical finding in Alzheimer s disease patients, and it is actually listed as a symptom consistent with the diagnosis of Alzheimer s disease, but its significance has not been clearly understood until now. This review examines the role of the components of energy balance in determining weight loss in AD patients, on the basis of data collected from the literature. We also considered the possible causes of anorexia in AD patients. In the last years many researchers investigated the possible role of abnormally high energy expenditure, or low energy intakes, or both, to explain weight loss in these patients. Studies on energy intake, energy expenditure and body composition in AD patients have been reviewed. The results of published studies do not seem to support the hypothesis of an hypermetabolic state or inadequate energy intake in AD patients, but further studies, with greater samples are necessary in the future to investigate weight loss in AD patients. A better understanding of this finding could be important to obtain the maximal lifespan of demented patients.
