Abstract
Background
Metabolic healthy obesity (MHO), as one phenotype of obesity, seems associate with lower risk of cardiovascular disease. However, MHO has close relationship with higher incidence of metabolic syndrome and diabetes. This study aims to investigate the prevalence of MHO at baseline, changes of obese metabolic phenotype at follow-up and its relationship with incidence of mildly reduced estimated glomerular filtration rate (eGFR) in rural Northeast Chinese.
Methods
The Chronic Kidney Disease Epidemiology (CKD-EPI) equation was used to calculate eGFR. 4903 participants aged ≥ 35 years with eGFR > 90 ml/min/1.73 m2 at baseline were enrolled and successfully followed up. All participants completed the questionnaires, anthropometric measurements, and blood test during baseline and follow-up. Mild renal dysfunction defined as mildly reduced eGFR between 60–90 ml/min/1.73 m2.
Results
The prevalence of MHO was 20.04% in baseline (18.97% for women and 21.11% for men) which was secondary to metabolic abnormal obesity (MAO) (24.4%, 27.2% for women and 21.5% for men). 38.4% of women and 38.90% of men experienced phenotype changes during follow-up. The cumulative incidence of mildly reduced eGFR in MHO was 20.1% (17.7% for women and 22.3% for men) which was also secondary to MAO (20.8%, 18.6% for women and 23.5% for men). After adjusted possible confounders, MHO was associated with higher incidence of mildly reduced eGFR among women [OR (95%CI) = 1.64 (1.18, 2.25)] and men [OR (95%CI) = 1.62 (1.24, 2.11)] whereas MAO was related with higher incidence of mildly reduced eGFR among men only [OR (95%CI) = 1.74 (1.32, 2.29)].
Conclusion
MHO was associated with higher incidence of mildly reduced eGFR in both gender; however, there was a specific relationship between MAO and mildly reduced eGFR in men only. Therefore, it is necessary to monitoring kidney function among both MHO and MAO subjects.
