Metabolic obesity phenotypes and all-cause mortality among the Chinese oldest-old population: a prospective cohort study
Authors' conclusion
MHO predicts better survival among the Chinese oldest-old population. These findings suggest that ensuring optimal management of metabolic health is beneficial and taking caution in weight loss based on the individual body weight for the metabolically healthy oldest-old adults.
