The Proportion of Dietary Protein Digested as Measured by the Dual-isotope Method.

October 6, 2023 updated by: Universitaire Ziekenhuizen KU Leuven
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.

Study Overview

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).
