Abstract
Gender is an important risk factor for the development of obesity. Female gender is associated with twice the risk of being overweight or having obesity. Women are also at higher risk for developing obesity-related physical and psychological comorbidities and have a twofold higher mortality risk than overweight men. Several risk factors have been described to explain the gender bias associated with an obese phenotype and these disparities have far-reaching implications on the medical, psychosocial, and the economical impact of an individual. Despite extensive awareness about gender differences related to obesity, this is still considered as an unchartered territory in obesity medicine. This is probably because of the complex multiple dimensions involved with the understanding of subject coupled with the lack of composite outcomes measures that could assist in the study of these factors. In this scoping review, we share the existing literature regarding the magnitude of gender disparities and gender discrimination in people living with obesity. We describe key factors leading to this gender bias and the impact of this discrimination on the psychological, social, and metabolic health of a given individual with obesity. We also discuss the possible implications of gender disparities on treatment of obesity which may help reduce the current mortality gap between overweight women and men.
