Participants were categorized into four phenotypes based on BMI or WC and metabolic status: metabolically healthy normal weight, metabolically healthy with obesity (MHO), metabolically unhealthy normal weight (MUNW), and metabolically unhealthy with obesity (MUO). Cox regression models were used to estimate hazard ratios (HRs) for all-cause mortality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      During follow-up, 193 deaths were recorded. When obesity was defined by BMI, only MUO was significantly associated with increased mortality (fully adjusted HR = 1.659, 95% confidence interval [CI]: 1.122\u20132.452,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.011). When defined by WC, both MHO (HR = 1.823, 95% CI: 1.037\u20133.203,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.037) and MUO (HR = 1.964, 95% CI: 1.273\u20133.029,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.002) showed significantly higher risks. Subgroup analyses revealed that WC-defined MHO conferred increased mortality only in men and in younger participants (&lt;64 years).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>In conclusion, WC is a superior predictor of all-cause mortality to BMI, particularly in men. The MHO phenotype is not uniformly benign, especially when defined by central adiposity.
