The aim of this study is to determine the concentrations of blood pressure, serum lipoproteins, glucose and insulin levels as well as the concentrations of α-klotho and FGF-23 parameters. We also aim at the correlation between all these parameters in obese prediabetics and obese normoglycemics. Material methods: A total of 26 obese normoglycemic (control group) and 25 obese prediabetic individuals were included in this study. Glucose, haemoglobin A1c (HbA1c) and cholesterols levels were analyzed as part of a routine procedure in the biochemistry laboratories of our hospital using an autoanalyzer. In order to determine α-klotho and fibroblast growth factor-23 (FGF-23) levels, ELISA method was used. Result: According to the findings, a significant increase was detected in serum LDL-C, TC, HbA1c, glucose, insulin and HOMA-IR levels in the obese prediabetic group compared to the control group (p <0.05). However, serum α-klotho and FGF-23 levels were found to be significantly lower in the obese prediabetic group compared to the control group (p <0.05). α-klotho and FGF-23 values showed strong negative correlation when compared with HOMA-IR values separately (p <0.01). Conclusion: These findings suggest that α-klotho and / or FGF-23 parameters may be a marker for prediabetes. The results of our study, together with the future studies, will make a significant contribution to the literature, as prediabetes diagnostic criteria in the diabetes outpatient clinics.}, number={2}, publisher={Zonguldak Bulent Ecevit University}, organization={Zonguldak Bülent Ecevit University Scientific Research Projects}
