Abstract

The present study aimed at identifying the difference in the risk of microalbuminuria among individuals with various obesity phenotypes in terms of metabolic health and obesity. This cross-sectional study included 15,268 individuals and used data from the National Health and Nutrition Survey conducted from 2011 to 2014. Obesity was defined as body mass index ≥25 kg/m². Metabolically unhealthy was defined as meeting two or more of the following criteria: systolic and diastolic blood pressure ≥130/85 mm Hg or current use of hypertensive drugs; triglyceride level ≥150 mg/dL; high-density lipoprotein level <40/50 mg/dL (in both men and women); and fasting blood glucose level ≥100 mg/dL or current use of oral antidiabetic medications. The participants were further classified into four subgroups: metabolically healthy non-obese (MHNO), metabolically healthy obese (MHO), metabolically unhealthy non-obese (MUNO), and metabolically unhealthy obese (MUO). A significant difference was observed in the microalbuminuria ratio among the four groups. The MHNO group was considered as the reference group, and the MHO, MUNO, and MUO groups were at an increased risk for microalbuminuria by 1.42 fold (95% confidence interval [95% CI], 1.03-1.96), 2.02 fold (95% CI, 1.61-2.53), and 3.40 fold (95% CI, 2.70-4.26), respectively, after adjusting confounding factors. The MUNO group had a higher risk of developing microalbuminuria than the MHNO group. Thus, based on this result, differences were observed in the risk of developing microalbuminuria among individuals with various obesity subtypes.
