Association of Adipocytokines with Lipid and Glycemic Profiles in Women with Normal Weight Obesity

Abstract

Background: Subjects with normal weight obesity (NOW) 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 controlsMaterial & Methods: Forty women with BMI:18.5-24.9 kg/m2 and FM ≥ 30% as a NOW group and 30 age matched women with same BMI range and FM<30% as control group were enrolled. Anthropometric measurement, fasting serum levels of fasting blood sugar (FBS), insulin, HbA1c, lipid profiles and also, leptin and vaspin were measured. Results: The mean ± SD of age were 28.76±4.76 years in NWO group and 29.23 ± 4.50 years in controls. Subjects in NWO group had higher serum level 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 HOMA-IR (33.77 ± 20.71 vs. 23.48 ± 10.03, p=0.009) compared to the NWNO group. Serum level of vaspin was higher in NWO (34.82 pg/ml) than control group (27.72 pg/ml),(p=0.12). In NWO subjects, serum level of leptin showed positive association 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 women with NWO had statistically significant increased concentration of insulin and HOMA-IR index compared to the controls. Higher levels of leptin and vaspin in NWO were associated with glycemic profiles in NWO.
