Incidence of metabolic and bariatric surgery among US adults with obesity by diabetes status: 2016–2020
Authors' conclusion
Incident MBS procedures were nearly threefold higher among adults with obesity and diabetes than those with obesity but without diabetes. Continued monitoring of the trends of MBS and other treatment modalities can inform our understanding of treatment accessibility to guide prevention efforts aimed at reducing obesity and diabetes.

Main finding
As reported in the abstract
Age- and sex-adjusted MBS incidence per 1000 adults
Observational data: associations, not effects.
Further findings
MBS incidence by sex, obesity class, region and surgical approach
- MBS incidence significantly higher for women and adults with class III obesity regardless of diabetes status
