” Fatores associados ao ganho de peso em mulheres em vulnerabilidade social.”

Abstract

The prevalence of overweight and obesity has shown a rapid increase in recent decades, being reflected in women in social vulnerability. The study of energy expenditure, physical activity and food intake are important to understand the factors associated with weight gain in this population. This study aimed to conduct a literature review to assess which factors might be interfering with the nutritional status and energy expenditure in individuals in social vulnerability especially in females. Thus, the thesis was divided into two parts: the first corresponds to a chapter review, in which it sought to explain the process of nutritional transition and the prevalence of overweight in Brazil and worldwide. The weight gain ratio and chronic diseases, energy expenditure, physical activity and food intake in populations in social vulnerability. The second part is a results paper, which aimed to determine the factors associated with anthropometric changes in women at social vulnerability for a period of two years. The result showed that after two years of follow-up of women in social vulnerability, there was an increase in BMI (<0.01), which is related to the underreporting at baseline. Physical inactivity represented by time sitting / lying was associated with increased waist / hip ratio (<0.01). Given the above the present study suggests that weight gain in this population evaluated was associated with sedentary behavior, reflected by time spent sitting / lying.
