Stages of change of behavior in women on a multi-professional program for treatment of obesity.

Objective: to ascertain the effectiveness of an intervention program in relation to anthropometric measurements and stage of readiness for behavioral change in women with excess weight.

Methods: the intervention group (IG) was made up of 13 women, and the control group (CG), by 20. The intervention lasted 16 weeks, and included the practice of guided physical activity three times a week, and health education once a week. The application of the questionnaire on stage of readiness for behavioral change, and the anthropometric evaluations, were undertaken at two points - before and after the period of intervention. The statistical analysis involved tests of comparison and association.

Results: in general, at the first point, the participants in the two groups were predisposed to make changes in what they ate and in their physical activity. However, significant difference was only observed in relation to weight, body mass index (BMI), waist circumference and waist-hip ratio and readiness for change among the members of the intervention group.

Conclusion: the intervention programmed was effective in weight loss, reduction of waist circumference and waist-hip ratio, and in changing behaviors related to the practicing of physical exercise and eating habits.
