    Frontal lobe functions and quality of life in individuals with obesity with and without binge eating disorder
    (Edições Universitárias Lusófonas, 2023-10-08) Gameiro, Fátima; Rosa, Beatriz; Faria, Miguel; Instituto de Serviço Social
    Frontal lobe functions (FLFs) play an important role in human behavioral regulation and can be a determinant of eating behavior. The aim of this study was to analyse FLFs in individuals with obesity, with and without binge eating disorder (BED), compared to individuals with normal weight (NW), and to analyse the effect of sex and binge disorder on quality of life, with age and BMI as covariates. A total of 114 participants, comprising three different groups (NW individuals, individuals with obesity but without BED, and individuals with obesity and BED), completed the Frontal Assessment Battery (FAB) and Impact of Weight on Quality of Life (IWQOL-lite) questionnaires. The results showed that individuals with obesity, with and without BED, have poorer frontal lobe functioning than the NW group. Individuals with obesity and BED have lower performance in terms of FLFs than individuals with obesity but without BED. Male participants have a higher perception of quality of life in all dimensions, with women showing lower values in self-esteem and sex life. Individuals with obesity and BED show greater weaknesses in physical function. These results suggest that low FLFs and worse quality of life characterize individuals with obesity, and this is more evident in these individuals with BED.
