Abstract

In this case-control study, 60 patients with Polycystic ovary syndrome (PCOS) referred to the Nursing and Midwifery Center of Khorramabad, were selected as the case group and 90 non-PCOS patients as the control group. Demographic information and anthropometric indices of each person were collected. The Food Frequency Questionnaire (FFQ) and International Physical Activity Questionnaire (IPAQ) were completed. After at least 12 h of fasting, 7 mL of blood samples were taken from the patients. There was no statistically significant difference observed in the mean of the total antioxidant capacity (TAC) between the two groups. However, a statistically significant difference was found between the two groups in terms of malondialdehyde (MDA) and some dietary antioxidants levels (mean in case group: vit C = 34/2 mg, vit E = 7/7 mg, Se = 84/6 µg, Zn = 7/5 mg, beta-carotene = 762/8 µg, mean in control group: vit C = 72/5 mg, vit E = 10/6 mg, Se = 91/0 µg, Zn = 10/6 mg, beta-carotene = 1609/5 µg).IMPACT STATEMENTWhat is already known on this subject? Polycystic ovary syndrome (PCOS) is one of the most common endocrine abnormalities and is considered as the main cause of infertility. Some studies have evaluated the link between dietary intakes and oxidative stress markers in PCOS patients. It is well known that about 40–50% of individuals with PCOS are obese and that leads to an increase in lipid catabolism and production of free radicals and oxidative stress. What the results of this study add? The aim of the present study was to compare the level of dietary antioxidants and oxidative stress markers including TAC, MDA and abdominal obesity prevalence in PCOS patients with healthy individuals. What the implications are of these findings for clinical practice and/or further research? We hope that our study can be influential in the field of PCOS. Furthermore, our findings have indicated a statistically significant difference between the two groups in terms of MDA and some dietary antioxidants levels. This result might be encouraging in using antioxidant in patients with PCOS. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.
