Clinical Trial Summary

The retrospective cohort study will compare the prevalence of sarcopenia and associated factors between older patients who have undergone bariatric surgery and older patients with obesity without previous bariatric surgery.

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).

Type	Measure	Description	Time frame	Safety issue
Primary	The number of older patients with sarcopenia after bariatric surgery compared to non-surgical control patients.	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.	At least one year post surgery
Secondary	1. Appendicular skeletal muscle mass older of patients after bariatric surgery compared to non-surgical control patients	1. Appendicular skeletal muscle mass older of patients after bariatric surgery compared to non-surgical control patients	At least one year post surgery
Secondary	2. The prevalence of nutrient deficiencies in older patients after bariatric surgery compared to non-surgical control patients.	a. Indices of nutrient deficiencies will include reported dietary intake of protein, zinc, selenium, and blood levels of Vitamin D, zinc, and selenium.	At least one year post surgery
Secondary	3. Markers of chronic systemic inflammation in older patients after bariatric surgery compared to non-surgical control patients	Inflammatory markers will include CRP, IL-1ß, IL-6, IL-8, TNF-a	At least one year post surgery
