Few studies have examined whether metabolically healthy overweight or obesity (MHO) may contribute to GFD.<\/jats:p><\/jats:sec>Objective<\/jats:title>To evaluate associations of overweight or obesity and metabolic disorders with GFD in recipients of kidney transplant.<\/jats:p><\/jats:sec>Design, Setting, and Participants<\/jats:title>This multicenter retrospective cohort study was conducted from January 1, 2020, through June 30, 2021, with a follow-up period of 2 years after kidney transplantation. Participants included adult recipients of cadaveric kidney transplant in 4 transplantation centers in China. Participants were classified as 4 metabolic phenotypes according to their BMI and metabolic status. Data were analyzed from July to August 2023.<\/jats:p><\/jats:sec>Exposures<\/jats:title>Overweight and obesity were characterized by body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) of 24 or greater. Metabolic disorder was identified by existence of a minimum of 2 of 4 conditions: hypertension, hyperglycemia, increased triglyceride, and decreased high-density lipoprotein cholesterol.<\/jats:p><\/jats:sec>Main Outcome and Measures<\/jats:title>The main outcome was GFD, defined as a decrease in estimated glomerular filtration rate of at least 25% within 6 months to 2 years after transplant.<\/jats:p><\/jats:sec>Results<\/jats:title>A total of 1260 adult recipients of cadaveric kidney transplant (mean [SD] age, 43.97 [11.51] years; 755 [59.92%] male) were included in the study, and 127 (10.08%) participants experienced the primary outcome of GFD during follow-up. After accounting for confounding factors in multivariable analyses, overweight or obesity (odds ratio [OR], 1.64; 95% CI, 1.10-2.44; P<\/jats:italic>\u2009=\u2009.02) and metabolic disorder (OR, 1.71; 95% CI, 1.12-2.63; P<\/jats:italic>\u2009=\u2009.01) were associated with increased risk of GFD. The MHO subgroup exhibited a greater risk for GFD (OR, 2.37; 95% CI, 1.01-5.57; P<\/jats:italic>\u2009=\u2009.048) compared with participants who did not have overweight or obesity or metabolic disorder. All components of metabolic disorder, with the exception of elevated triglyceride, were associated with GFD. There was a dose-response association of number of metabolic disorder components (OR per 1 additional condition, 1.40; 95% CI, 1.20-1.63; P<\/jats:italic>\u2009&amp;lt;\u2009.001) and BMI (OR per 1-unit increase, 1.90; 95% CI, 1.03-1.15; P<\/jats:italic>\u2009=\u2009.002) with increased risk for GFD. A nonlinear association was observed between BMI and risk of GFD.<\/jats:p><\/jats:sec>Conclusions and Relevance<\/jats:title>In this cohort study of recipients of cadaveric kidney transplant, individuals with overweight or obesity or metabolic disorder had a significantly higher risk of experiencing GFD. Individuals with MHO had an elevated risk for graft function deterioration. Additional studies with larger sample size and longer follow-up are necessary to validate our findings.<\/jats:p><\/jats:sec>","DOI":"10.1001\/jamanetworkopen.2023.49538","type":"journal-article","created":{"date-parts":[[2023,12,27]],"date-time":"2023-12-27T16:32:46Z","timestamp":1703694766000},"page":"e2349538","source":"Crossref","is-referenced-by-count":12,"title":["Metabolic
