Methods: This study was conducted as a single-centre, cross-sectional study. Results: The study included 90 participants: 35 women (38.9%) and 55 men (61.1%). Of the participants included in the study, 30 were normal weight (33.3%) (Group 1), 30 were overweight (33.3%) (Group 2), and 30 were obese (33.3%) (Group 3). There were statistically significant differences in the &lt;span style=\"color: rgb(32, 33, 34); font-family: sans-serif; font-size: 16px; background-color: rgb(248, 249, 250);\"&gt;\u03b1&lt;\/span&gt;-KL protein (p = 0.010), hsCRP (p&amp;lt; 0.001), and homeostasis model assessment of insulin resistance (HOMA-IR) (p = 0.022) between the study groups. There is no significant difference between the study groups for CIMT (p= 0.380), TOS (p= 0.613), TAS (p= 0.056), or OSI (p= 0.943). Conclusions: In this study, the overweight group had a-KL protein levels that were significantly higher than those in the obese group, whereas hsCRP levels were significantly higher in the obese group than in the overweight and normal weight groups. There were no significant differences in CIMT, TAS, TOS, and OSI values between the study groups. There were no significant correlations between &lt;span style=\"color: rgb(32, 33, 34); font-family: sans-serif; font-size: 16px; background-color: rgb(248, 249, 250);\"&gt;\u03b1&lt;\/span&gt;-KL protein values and BMI, hsCRP CIMT, TAS, TOS, or OSI in participants in the study.<\/jats:p>","DOI":"10.5937\/jomb0-60664","type":"journal-article","created":{"date-parts":[[2026,1,26]],"date-time":"2026-01-26T09:19:02Z","timestamp":1769419142000},"page":"1307-1315","source":"Crossref","is-referenced-by-count":0,"title":["Evaluation of plasma Alpha klotho levels in obese cases"],"prefix":"10.5937","volume":"45","author":[{"given":"Ibrahim","family":"Solak","sequence":"first","affiliation":[{"name":"University of Health Sciences, Department of Family Medicine, Konya Beyhekim Health Application and Research Centre, Konya, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ibrahim","family":"Guney","sequence":"additional","affiliation":[{"name":"Konya City Hospital, University of Health Sciences, Division of Nephrology, Department of Internal Medicine, Konya, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nevin","family":"Sekmenli","sequence":"additional","affiliation":[{"name":"University of Health Sciences, Department of Radiology, Konya City Hospital, Konya, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huseyin","family":"Kurku","sequence":"additional","affiliation":[{"name":"University of Health Sciences, Department of Biochemistry, Konya City Hospital, Konya, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"Ali","given":"Mehmet","family":"Eryilmaz","sequence":"additional","affiliation":[{"name":"University of Health Sciences, Department of General Surgery, Konya City Hospital, Konya, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3964","reference":[{"key":"ref1","unstructured":"World Health Organization.
