Abstract(s)
O insucesso na manutenção do peso perdido contribui para as taxas de obesidade e excesso de
peso. A capacidade de manutenção tem sido associada à regulação do comportamento
alimentar. As Orientações para o Bem-estar – motivos e valores do sujeito – influenciam o
comportamento e os seus resultados. Este estudo pretende analisar se existe uma relação entre
as Orientações para o Bem-estar e a Manutenção do Peso Perdido, mediada pela Regulação do
Comportamento Alimentar. Participaram 143 sujeitos entre os 18 e os 68 anos (M= 35.50;
DP= 15.10), que perderam peso nos últimos 5 anos. As Orientações e a Regulação do
Comportamento Alimentar foram avaliadas pela versão portuguesa da Hedonic, Eudaimonic
and Extrinsic Motives for Activities e da Regulation of Eating Behavior Scale, respetivamente.
Não foi encontrada qualquer relação entre a Manutenção do Peso Perdido e as Orientações ou
a Regulação do Comportamento Alimentar. Contudo, as Orientações associaram-se
distintamente aos tipos de Regulação do Comportamento Alimentar: os indivíduos com níveis
superiores de Orientação Eudaimónica e Hedónica apresentam uma regulação do
comportamento alimentar mais autodeterminada; enquanto níveis superiores de Orientação
Extrínseca se associam a uma regulação mais controlada. Níveis mais elevados de Orientação
Eudaimónica associam-se também a uma quantidade superior de peso perdido. Além disso, o
grupo que cumpriu o objetivo de quilogramas a perder, comparativamente ao que não
cumpriu, apresenta níveis superiores de Orientação Eudaimónica e Hedónica e de Motivação
Intrínseca, e inferiores de Regulação Introjetada. Limitações e implicações para a regulação
do comportamento alimentar e gestão do peso são discutidos.
ABSTRACT: Failing to maintain lost weight is one of the main contributors to the rising rates of obesity and overweight. Studies suggest that the ability to maintain weight is linked to the autonomous regulation of eating behaviour. Well-being Orientations – personal motives and values – influence behaviour and its outcomes. The present study aims to analyse the relationship between Well-being Orientations and Weight Maintenance, and whether the Regulation of Eating Behaviour mediates this relationship. 143 subjects aged between 18 and 68 (M= 35.50; SD= 15.10), who had lost weight within the last five years, participated in this study. The portuguese versions of the Hedonic, Eudaimonic and Extrinsic Motives for Activities and the Regulation of Eating Behaviour Scale were used to assess the Well-being Orientations and the Regulation of Eating Behaviour, respectively. The findings indicate that Weight Maintenance is not related to either the Well-being Orientations or the Regulation of Eating Behaviour. However, the Orientations are distinctly associated with different types of eating behaviour regulation: while Hedonic and Eudaimonic Orientations are positively linked to more self-determined regulation, Extrinsic Orientation is positively linked to more controlled regulation. Higher levels of Eudaimonic Orientation are also associated with greater weight loss. Furthermore, the group that achieved their weight loss goal, compared to those who did not meet their target, showed higher levels of Hedonic and Eudaimonic Orientation and Intrinsic Regulation, and lower levels of Introjected Regulation. Limitations and implications for weight management and regulation of eating behaviour are discussed.
