Detailed Description
The aim of the study is to compare the prevalence of sarcopenia and nutritional status between adults older than 65 years who have previously undergone bariatric surgery and patients with obesity but without previous bariatric surgery. Current sarcopenia will be assessed during a cross-sectional assessment after surgery using the criteria from the European Working Group on Sarcopenia in Older People (EWGSOP).

Outcome Measures
Primary Outcome Measures
- The number of older patients with sarcopenia after bariatric surgery compared to non-surgical control patients. [At least one year post surgery]
a) Sarcopenia will be classified according to the criteria form the European Working Group on Sarcopenia in Older People revised guidelines (EWGSOP2) based on skeletal muscle mass, muscle strength and physical performance criteria.
Secondary Outcome Measures
- 1. Appendicular skeletal muscle mass older of patients after bariatric surgery compared to non-surgical control patients [At least one year post surgery]
1. Appendicular skeletal muscle mass older of patients after bariatric surgery compared to non-surgical control patients
- 2. The prevalence of nutrient deficiencies in older patients after bariatric surgery compared to non-surgical control patients. [At least one year post surgery]
a. Indices of nutrient deficiencies will include reported dietary intake of protein, zinc, selenium, and blood levels of Vitamin D, zinc, and selenium.
- 3. Markers of chronic systemic inflammation in older patients after bariatric surgery compared to non-surgical control patients [At least one year post surgery]
Inflammatory markers will include CRP, IL-1β, IL-6, IL-8, TNF-α
