“…In Turkey, as in other countries around the world, vitamin D deficiency is endemic. Authors in a recent study claimed that 94.47% of women living in Turkey had serum 25(OH)D levels of less than 30 ng/ml, 76.25% had serum 25(OH)D levels of less than 20 ng/ml, and 32.20% had serum 25(OH)D levels of less than 10 ng/ml 11 .…”

Introduction It is still unclear in the literature whether low vitamin D levels play a role in the pathogenesis of polycystic ovary syndrome (PCOS), especially with respect to the regulation of anti-Müllerian hormone (AMH). Therefore, we aimed to investigate whether there could be a relationship between vitamin D deficiency status and PCOS. Materials and Methods A total of 146 infertile women were divided into two groups according to their ovarian reserve patterns: (i) normal (NOR), and (ii) high (PCOS). The participants were also categorized into two groups according to vitamin D concentrations: (i) Group A < 10 ng/mL, and (ii) Group B 10 – 20 ng/mL. Samples were obtained and analyzed for estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), total testosterone (TT), 17-hydroxyprogesterone (17-OHP), dehydroepiandrosterone sulfate (DHEA-S) and AMH. Results In the NOR group, there were significant differences between Group A and Group B in terms of anthropometric characteristics (p < 0.05, for all). The women in both Group A and Group B had similar AMH concentrations (p > 0.005). Only the NOR group showed a significant though moderate negative correlation between 25(OH)D levels and anthropometric parameters. AMH levels were not correlated with 25(OH)D levels in the NOR or the PCOS group (r = − 0.112, p = 0.008; r = 0.027, p = 0.836). Multivariate regression analysis showed no impact of 25(OH)D on other study parameters. Only AMH measurements were significant enough (p < 0.001) to differentiate between PCOS and NOR patterns. Conclusion We found no difference in serum 25(OH)D and AMH levels between women with and women without PCOS. No correlation could be demonstrated between 25(OH)D and AMH in the PCOS group or controls.

“…The findings of the present study are consistent with those of previous studies. Vitamin D deficiency is common in general population beacuse of living style (14). The rate of D vitamin deficiency/insufficiency with BTM was similar to general population.…”

“…The average Vitamin D level of the participants in this study was found to be 32.4±15.3 (ng/mL). In their retrospective study, Solak et al (2018) found the average serum 25-hydroxyvitamin D level as 15.2 ± 8.8 ng/ml. Other studies investigating the Vitamin D levels also reported that the 25-hydroxyvitamin D level was lower than 20ng/mL (Katrinaki et al, 2016;Mansoor et al, 2010;Yu et al, 2015).…”

Background: Vitamin D deficiency is today acknowledged as a pandemic. Vitamin D deficiency and insufficiency are associated with many chronic diseases, including common cancers, cardiovascular diseases, metabolic syndrome, and infectious and autoimmune diseases.Objective: This study aims to investigate the relationship between the cotinine level in urine and Vitamin D.Methods: This study employed a descriptive and relational screening design. It was conducted with 74 smoking university students between January 2019 and March 2020. Data were collected through socio-demographic form and Fagerstrom test for nicotine dependence. Besides, the participating students’ blood and urine samples were taken in a suitable environment.Results: The average age of the participating students was 21.50±2.09. Of all the students, 71.6% were males, 62.2% were exposed to the sun between 12 p.m. and 2 p.m., and the average number of cigarettes smoked daily was 13.52±8.22. The average Vitamin D level in blood was 32.4±15.3 (ng/mL), and the average cotinine level in urine was 1.60 ± .32 (ng/L). No statistically significant relationships were found between the Vitamin D level and the cotinine level (p<0.05).Conclusion: Smoking causes diseases and death in many people, and it is a changeable risk factor. Nursing practices on the struggle against smoking are effective. No significant relationships were found between the Vitamin D level in blood and cotinine level in urine. Similar studies are recommended to be conducted with larger groups and participants from different age groups.
