Abstract

Introduction: Polycystic ovary syndrome (PCOS) is a common endocrine disorder affecting many women of reproductive age. This systematic review was performed with aim to determine the effects of the Dietary Approaches to Stop Hypertension (DASH) on metabolic outcomes, oxidative stress, inflammatory factors and sex hormones in patients with PCOS.
Methods: In this systematic review, the keywords related to PCOS, lipid profile, glycemic status, anthropometric factors, oxidative stress, inflammatory factors, sex hormones, and DASH were searched in databases including Medline, Scopus, Embase, Science Direct, Magiran, ISD, ISC, and Cochrane in both Persian and English languages until January 2024.
Results: Four original research articles with a clinical trial design and an intervention period of 8-12 weeks using the DASH in PCOS patients were analyzed. The findings of these studies showed that following the DASH led to weight loss, reduced body mass index, waist circumference, and hip circumference. It also resulted in lower serum levels of triglycerides, very low density lipoproteins, insulin resistance, androstenedione, antimullerin hormone, free androgen index, malondialdehyde, and high-sensitivity C-reactive protein. Additionally, it was associated with improved sensitivity to insulin, increased total plasma antioxidant capacity, higher levels of total glutathione, sex hormone-binding globulin, and nitric oxide in the blood.
Conclusion: Following the DASH is associated with various health benefits, including weight loss, improved lipid profile, antioxidant status, sex hormones, insulin sensitivity, and markers of oxidative stress and inflammation in PCOS patients.
