Association of Adipocytokines with Lipid and Glycemic Profiles in Women with Normal Weight Obesity
Abstract Background: Subjects with normal weight obesity (NWO) are supposed to cardiometabolic disorders. The aim of this study was to investigate the circulating levels of vaspin and leptin and their association with glycemic and lipid profiles in women with NWO compared to controlsMethods: Forty women with body mass index (BMI)=18.5-24.9 kg/m2 and fat mass (FM) ≥ 30% as NWO group and 30 age matched women with same BMI range and FM<30% as control group were enrolled in this study. Anthropometric measurement, fasting serum levels of blood sugar (FBS), insulin, Glycated hemoglobin (HbA1c), lipid profiles and also, leptin and vaspin were measured.Results: The mean ± standard deviation (SD) of age was 28.76 ± 4.76 years in NWO group and 29.23 ± 4.50 years in controls. Subjects in NWO group had higher serum levels of insulin (9.02 ± 4.75 vs.6.24 ± 2.51, p= 0.009), leptin (17.31 ± 8.10 vs. 9.94 ± 4.30, p<0.001) and homeostatic model assessment for insulin resistance (HOMA-IR) (33.77 ± 20.71 vs. 23.48 ± 10.03, p=0.009) as compared to normal weight non-obese (NWNO) as control group. Serum level of vaspin in NWO group (34.82 pg/ml) was higher than that in controls (27.72 pg/ml), (p=0.12). In NWO group, serum level of leptin was correlated positively with FBS (r=0.45, p=0.02), insulin (r=0.51, p=0.008), and HOMA-IR (r=0.46, p=0.02) and vaspin concentration was positively associated with insulin (r=0.36, p= 0.02) and HOMA-IR (r=0.30, p=0.06). Conclusion: We observed that concentration of insulin and HOMA-IR index were significantly increased in women with NWO compared to the controls. Higher levels of leptin and vaspin in NWO were associated with glycemic profiles in NWO group.
