Therefore, we aimed to elucidate the role of 25\u2010OH vitamin D deficiency in arterial stiffness development and its relationship with arterial stiffness in healthy children.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This study included 80 patients with low levels of 25\u2010OH vitamin D and 40 healthy control subjects. The study participants were then divided into three groups: group 1 consisted of patients with a deficient 25\u2010OH D level of\u00a0&lt;\u00a019.9\u00a0ng\/ml, group 2 with an insufficient 25\u2010OH D level between 20 and 29.9\u00a0ng\/ml; group 3 were considered control group with a sufficient serum 25\u2010OH vitamin D level of \u226530\u00a0ng\/ml. Aortic strain, distensibility, stiffness index, and standard left ventricular measurements were calculated using M\u2010mode echocardiographic data.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Left ventricular mass index (LVMI) and\u2009inter\u2010ventricular septal diastolic thickness (IVST) appeared to increase in group 1 compared to groups 2 and 3. Aortic strain and distensibility were significantly decreased in group 1, whereas aortic stiffness index and elastic modulus were significantly increased. The aortic stiffness index was negatively correlated with serum 25\u2010OH vitamin D levels; however, aortic strain, aortic distensibility, and LVMI were positively correlated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our study results revealed a significant relationship between 25\u2010OH vitamin D levels indicative of a deficiency and aortic stiffness. Hence, we suggest that arterial stiffness may also occur in healthy children with a 25\u2010OH vitamin D deficiency. Future in\u2010depth studies are needed to understand the exact mechanisms underlying the aortic stiffness development associated with 25\u2010OH vitamin D deficiency.<\/jats:p><\/jats:sec>","DOI":"10.1111\/echo.15248","type":"journal-article","created":{"date-parts":[[2021,11,10]],"date-time":"2021-11-10T05:55:23Z","timestamp":1636523723000},"page":"1941-1947","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Low serum 25\u2010Hydroxy (OH) vitamin D levels are associated with increased arterial stiffness in healthy children: An echocardiographic study from Turkey"],"prefix":"10.1111","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2466-3285","authenticated-orcid":false,"given":"Emine","family":"Azak","sequence":"first","affiliation":[{"name":"Department of Pediatric Cardiology Ankara City Hospital University of Health Sciences  \u00c7ankaya\/Ankara Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ibrahim Ilker","family":"Cetin","sequence":"additional","affiliation":[{"name":"Department of Pediatric Cardiology Faculty of Medicine.
