Brief Summary
Context: Obesity, defined as excessive body fat, can lead to disability and loss of autonomy. If there is concomitant quantitative and qualitative muscle loss, sarcopenic obesity (SO) is suspected in this context. Although this clinical entity was defined several years ago, it is only very recently that precise assessment criteria have been established for screening and diagnosing this pathology (Donini et al. 2022). Defined by the ESPEN/EASO consensus, SO has various consequences for health, particularly in terms of mobility and worsening of co-morbidities. It is therefore necessary to screen for SO, to determine its prevalence in the general population and to identify the determining factors in the loss of muscle mass during obesity. Most studies on the prevalence of sarcopenic obesity focus on the elderly population, bearing in mind that the prevalence of this syndrome in the elderly will increase rapidly as a result of the shift in the incidence of obesity from adults to this population in the coming decades. The aim of this project is to determine the prevalence and determining or predisposing factors for sarcopenic obesity in a population of obese people in a broad age range (18-70 years). Longitudinal follow-up of this cohort is planned in order to assess multifactorial changes (body composition, muscle function and physical performance) at 5 and 10 years after their inclusion in the OBESAR-2 study. In addition, patients who have undergone bariatric surgery will also be followed in the shorter term to analyse the phenotypic changes induced by rapid weight loss on muscle loss.

Outcome Measures
Primary Outcomes (1)
To estimate the prevalence of sarcopenia in a population of adult subjects with obesity, at baseline and at 5 and 10 years.
The primary endpoint is the presence of sarcopenic obesity at inclusion, 5 years and 10 years post-inclusion, assessed according to the latest current recommendations, i.e. impaired muscle function and impaired body composition (Donini et al. 2022). A patient presents with sarcopenic obesity when there is an alteration in muscle function AND an alteration in body composition. For impaired muscular function, strength measured with the handgrip is considered pathological when it is less than 27kg for men and less than 16kg for women. Altered body composition is considered to exist when fat mass is greater than 39, 41 and 43% for women aged between 20 and 39, 40 and 59, and 60 and 79 respectively, and greater than 26, 29 and 31% for men aged between 20 and 39, 40 and 59, and 60 and 79 respectively, AND SMM/W (Skeletal Muscle Mass/Weight) is less than 37% in men and 27.6% in women.
