Common symptoms include irregular menstrual cycle, polycystic ovaries, and hirsutism, as well as an increased risk for a multitude of conditions, including insulin resistance, dyslipidemia and infertility. The prevalence of polycystic ovarian syndrome is generally thought to be between 3% and 10% but it is widely unknown for specific subpopulations based on geographical location and race\/ethnicity. Based on the high degree of variability and inconsistencies between the different diagnostic criteria, there is a unique challenge that exists when determining the prevalence of this syndrome. There are a large percentage of individuals that remain undiagnosed even after visiting multiple health care providers. Most studies conducted across the world are limited by small sample size, selection bias, and lack of comparability across studies. There have been very few studies that have examined the prevalence of polycystic ovary syndrome across the United States. Based on the National Institutes of Health (NIH)\u2019s diagnostic criteria, there is a similar prevalence of PCOS documented across the United States, the United Kingdom, Spain, Greece, Australia, and Mexico. Other studies have shown some differences between geographical location and race. The existing data is not conclusive enough to determine whether or not there is any significant differences in the prevalence of PCOS across geographical location, racial or ethnic groups. This review will seek to determine the prevalence of polycystic ovarian syndrome based on geographical location and race\/ethnicity.<\/jats:p>","DOI":"10.3390\/ijerph15112589","type":"journal-article","created":{"date-parts":[[2018,11,21]],"date-time":"2018-11-21T11:23:27Z","timestamp":1542799407000},"page":"2589","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":346,"title":["Geographical Prevalence of Polycystic Ovary Syndrome as Determined by Region and Race\/Ethnicity"],"prefix":"10.3390","volume":"15","author":[{"given":"Wendy M.","family":"Wolf","sequence":"first","affiliation":[{"name":"Physician Assistant and Registered Dietitian at Apex Family Medicine, Denver, CO 80209, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachel A.","family":"Wattick","sequence":"additional","affiliation":[{"name":"Department of Human Nutrition and Foods, West Virginia University, Morgantown, WV 26506, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olivia N.","family":"Kinkade","sequence":"additional","affiliation":[{"name":"Department of Human Nutrition and Foods, West Virginia University, Morgantown, WV 26506, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6686-3891","authenticated-orcid":false,"given":"Melissa D.","family":"Olfert","sequence":"additional","affiliation":[{"name":"Department of Human Nutrition and Foods, West Virginia University, Morgantown, WV 26506, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,11,20]]},"reference":[{"key":"ref_1","first-page":"299.e1","article-title":"Prevalence of polycystic ovary syndrome among the privately insured, United States, 2003\u20132008","volume":"207","author":"Okoroh","year":"2012","journal-title":"Obstet.
