Brief 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.

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).

Design outcomes

Primary

MeasureTime frameDescription
The number of older patients with sarcopenia after bariatric surgery compared to non-surgical control patients.At least one year post surgerya) 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

MeasureTime frameDescription
1. Appendicular skeletal muscle mass older of patients after bariatric surgery compared to non-surgical control patientsAt least one year post surgery1\. 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 surgerya. 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 patientsAt least one year post surgeryInflammatory markers will include CRP, IL-1β, IL-6, IL-8, TNF-α
