Abstract(s)
O tratamento de obesidade (OB) e a perda de peso bem-sucedida (PPBS) implica lidar
com barreiras e recursos. O presente estudo tem como objetivo investigar os fatores
associados à manutenção do peso em excesso, em pessoas que têm OB e pessoas que fizeram
uma PPBS.
Trinta homens e mulheres, com uma PPBS (n=15; perda no mínimo de 7% do peso
inicial e mantida por pelo menos 12 meses) ou com OB (n=15; IMC>30kg/m2), foram
entrevistados sobre fatores associados ao início do aumento de peso (PPBS e OB) e
associados à manutenção de peso excessivo no passado (PPBS) ou no presente (OB). As
entrevistas transcritas foram submetidas a uma análise de conteúdo e temática, por um júri de
dois psicólogos.
Na amostra de PPBS, a existência de problemas psicológicos tais como a ansiedade e a
depressão foram evidenciados como fatores que iniciaram o peso excessivo e a existência de
emoções negativas como fator que contribuiu para a manutenção desse peso. Na amostra de
OB, a ausência de exercício físico foi o fator mais mencionado a contribuir para o início da
obesidade e a alimentação desequilibrada como fator mais frequente a ajudar na manutenção
desse peso elevado. Existem contudo categorias comuns às duas subamostras.
Conclui-se que os fatores encontrados são de natureza variada, e grande parte são
fatores pessoais, com enfoque no sedentarismo e nas emoções negativas. A inclusão de ambos
os sexos em ambas as amostras e a análise de entrevistas gravadas, feitas em profundidade,
são vantagens para a potencial contribuição deste estudo.
ABSTRACT: Managing obesity (OB) and successful weight loss (SWL) entails dealing with barriers and resources. The present study aims to investigate factors associated with the maintenance of the excessive weight in people who currently have OB and people who have done a SWL. Thirty men and women, with a SWL (n=15; loss of a minimum of 7% of initial weight and maintained for at least 12 months) or with OB (n=15; BMI>30kg/m2), were interviewed regarding factors associated with weight gain (SWL and OB sample) and factors associated to the excessive weight maintenance in the past (SWL sample) or in the present (OB sample). The content of the transcribed; interviews were subjected to content and thematic analysis by a jury of two psychologists. In the SWL sample, the existence of psychological problems such as anxiety and depression were highlighted at the beginning of the excessive weight and the existence of negative emotions as a factor that contributed to the maintenance of this weight. In the OB sample, a lack of exercise has been shown as a factor that contributed to the beginning of obesity, and an unbalanced diet as a factor that helped to maintain the excessive weight. However, both subsamples have common categories. It follows that the factors found are varied in nature, and most are personal factors, focusing on physical inactivity and negative emotions. The inclusion of both sexes in both samples and analyzing recorded interviews made in depth are advantages to the potential contribution of this study.
