Methods: Thiol-disulfide homeostasis, Vitamin-D, ischemia modified albumin, insulin, and lipid levels were compared among obese, pre-obese and normal-weight healthy children. Results: A total of 136 children (69 boys and 67 girls) were included in the study. The vitamin-D levels of obese children were lower than those of pre-obese and normal weight (p &lt; 0.05). In the normal weight group, total thiol and native thiol were lower in the pubertal period than in adolescence; were higher in those with sufficient Vitamin-D level than those with insufficient and deficient Vitamin-D (p &lt; 0.05). Vitamin-D level was lower in pre-obese girls than boys (p &lt; 0.05). Those with high triglycerides had high disulfide/total thiol, disulfide, and disulfide/native thiol and low native thiol/total thiol (p &lt; 0.05). Conclusion: Thiol-disulfide homeostasis is negatively affected by low vitamin D levels, pubertal period and high triglyceride levels. © 2023 Taylor &amp; Francis Group, LLC.</dc:description><dc:publisher>Taylor and Francis Ltd.</dc:publisher><dc:date>2023</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/12064</dc:identifier><dc:identifier>https://doi.org/10.1080/15513815.2023.2183026</dc:identifier><dc:identifier>1551-3815</dc:identifier><dc:language>en</dc:language><dc:relation>Fetal and Pediatric Pathology</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/12064</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
