Autoeficácia para redução de gordura nas dietas e estágios de mudança de comportamento para perda de peso entre funcionários de escolas viçosenses Self-efficacy for fat reduction in diets and stages of change in behavior for weight loss among school employees in Viçosa, Brazil ABSTRACT ANDAKI A. C. R.; VIEIRA D. M.; OLIVEIRA M. C. F. Self-efficacy for fat reduction in diets and stages of change in behavior for weight loss among school employees in Viçosa, Brazil. Nutrire: rev. Soc. Bras. Alim. Nutr. = J. Brazilian Soc. Food Nutr., São Paulo, SP, v. 38, n. 2, p. 134-143, ago. 2013 In this study, we aimed to evaluate self-efficacy in a diet with reduced fat and identify stages of change in behavior for weight loss in employees of two schools in the municipality of Viçosa, Minas Gerais state. It is a crosssectional study with a sample of 21 subjects, 95% females. Weight and height were self-reported and nutritional status was obtained by the body mass index (BMI). We applied a questionnaire containing Likert Scale from 0 to 100 points to measure self-efficacy in following a diet with reduced fat. We calculated the average value of each individual: the score 0 classifies the individual as "not confident", 50 as "moderately confident", and 100 as "very confident". Algorithm was also used to identify the stages of change in behavior. Body weight was 60.75±12.73kg. Overweight and obesity accounted for 21.1% and 15.7% of the subjects analyzed, respectively. We verified that 50% of individuals did not maintain their desired weight for more than six months and that 50% actively attempted to lose weight in the last month; of these, 40% were aimed at weight loss in the following six months. Regarding stage changes, 50% of subjects were in the pre-contemplation stage; 30%, 5%, and 15% were in the preparation, action, and maintenance stages, respectively. Results showed that the individuals studied were moderately confident in following a diet with reduced fat, mean score of 40.68±21.96, and that most of them were in their pre-action stages. It is suggested that interventions be accomplished with school officials, among individuals who are in the stages of preparation and maintenance, to promote body weight reduction besides encouraging self-efficacy among the less confident. .
