Overview
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.
Interventions
- Other Collection of fluid samples
\- Blood sampling, urine sampling and tissue sampling
Primary outcome measures
- To estimate the prevalence of sarcopenia in a population of adult subjects with obesity, at baseline and at 5 and 10 years. [Time frame: Day 1 / 5 years /10 years]
Secondary outcome measures (11)
- % of patients with the factors associated with sarcopenia [Time frame: Day 1 / 5 years /10 years]
- concentration of biomarkers in a group of obese patients with sarcopenia using the biobank. [Time frame: Day 1 / 5 years /10 years]
- Evaluate the degree of severity of sarcopenic obesity over time using the ESPEN/EASO consensus staging system. [Time frame: Day 1 / 5 years /10 years]
- % change of parameters measured to identify the group at risk of accelerated decline [Time frame: 5 years /10 years]
- % of evolution of biomarkers [Time frame: Day 1 / 5 years /10 years]
- % of risk of various health problems (diabetes, hypertension, etc.) between sarcopenic and non-sarcopenic patients. [Time frame: Day 1 / 5 years /10 years]
- % of patients with the factors associated with sarcopenia in the subgroup of patients undergoing bariatric surgery. [Time frame: Day 1 /Day of surgery/ 6 months after surgery/ 12 months after surgery/ 5 years /10 years]]
- concentration of biomarkers in a group of obese patients with sarcopenia using the biobank in the subgroup of patients undergoing bariatric surgery. [Time frame: Day 1 /Day of surgery/ 6 months after surgery/ 12 months after surgery/ 5 years /10 years]]
- Evaluate the degree of severity of sarcopenic obesity over time using the ESPEN/EASO consensus staging system in the subgroup of patients undergoing bariatric surgery. [Time frame: Day 1 /Day of surgery/ 6 months after surgery/ 12 months after surgery/ 5 years /10 years]]
- % of evolution of biomarkers in the subgroup of patients undergoing bariatric surgery. [Time frame: Day 1 /Day of surgery/ 6 months after surgery/ 12 months after surgery/ 5 years /10 years]
- % of risk of various health problems (diabetes, hypertension, etc.) between sarcopenic and non-sarcopenic patients in the subgroup of patients undergoing bariatric surgery. [Time frame: Day 1 /Day of surgery/ 6 months after surgery/ 12 months after surgery/ 5 years /10 years]]
