Abstract

<b><i>Introduction:</i></b> Metabolic or inflammatory markers may predict adverse outcomes in women with obesity. We sought to describe metabolic-obesity phenotypes of women using novel staging tools and investigate relationships with inflammation. <b><i>Methods:</i></b> In a cross-sectional study, we collected fasting blood samples from sixty-four females with body mass index (BMI) ≥28 kg/m<sup>2</sup>. Participants were classified as metabolically healthy or metabolically unhealthy obesity (MUO) using the cardiometabolic disease staging system (CMDS) and Edmonton obesity staging system (EOSS). Data were analyzed using independent sample <i>t</i> tests, Pearson’s correlations, and multiple logistic regression. <b><i>Results:</i></b> Mean (SD) age was 40.2 (9.3) years with median (IQR) BMI 31.8 (30.3–35.7) kg/m<sup>2</sup>. The prevalence of MUO was 46.9% and 81.3% using CMDS and EOSS criteria, respectively. Women with raised CMDS scores had higher C3 (1.34 [0.20] vs. 1.18 [0.15], <i>p</i> = 0.001) and C-reactive protein (CRP) (2.89 [1.31–7.61] vs. 1.39 [0.74–3.60], <i>p</i> = 0.034). C3 correlated with insulin (<i>r</i> = 0.52), hemoglobin A1c (<i>r</i> = 0.37), and C-peptide (<i>r</i> = 0.58), all <i>p</i> &#x3c; 0.05. C3 above the median (&#x3e;1.23 g/L) increased odds of raised CMDS score, when controlled for age, BMI, ethnicity, and smoking (OR = 6.56, 95% CI: 1.63, 26.47, <i>p</i> = 0.008). <b><i>Conclusion:</i></b> The prevalence of MUO was lower using CMDS than EOSS. C3 and CRP may be useful clinical biomarkers of risk or treatment targets in women with obesity.
