Vitamin D and polycystic ovary syndrome : an integrating review

Abstract

Introduction: Polycystic ovary syndrome (PCOS) is the most common endocrinopathyin women of reproductive age. It causes a metabolic syndrome characterized by insulin resistance, hyperinsulinemia, and dyslipidemia. Vitamin D deficiency and its association with PCOS still represents a controversial subject in the literature.

Objective: In this context, this study aimed to understand the association between polycystic ovary syndrome and vitamin D deficiency, and how it occurs.

Method: It was an integrative review conducted in the PubMed, Scopus, LILACS, and CINAHL databases from August 2016 to January 2017, with a sample of 7 articles analyzed in their entirety.

Results: The evidences according to the studies conducted and the conclusions they identified. Conclusions: It was concluded that we cannot yet assume that vitamin D deficiency contributes to the pathogenesis of PCOS, nor that the syndrome causes vitamin D deficiency, since the studies are controversial and there is a need for research with higher levels of evidence to clarify these doubts.
