BACKGROUND: Polycystic ovarian syndrome (PCOS) is one of the most common endocrine dysfunction problems among women of the reproductive age, with a global prevalence of 4-20%, causing 430,000 associated DALYs. Initial treatment of PCOS is mainly focused on diet and exercise and, if left untreated, PCOS can lead to many complications including, but not limited to, diabetes, metabolic syndrome, cardiovascular disease and endometrial cancer. In India, one out of five women are found to have PCOS with the numbers increasing with every year, according to a 2015 study done by Metropolis Healthcare. Some studies done in other parts of the country have shown that there is very limited knowledge about PCOS. Currently there is no data about the knowledge, attitudes and practices about PCOS in Kerala, India, which is an area known to have the highest rates of diabetes in India as well as an area having a high rate of infertility. PROPOSED PROJECT AND SIGNIFICANCE: This study is proposed to assess the knowledge, attitudes and practices of PCOS among women of reproductive age (18-45 years) in urban and rural areas of Thrissur, Kerala, India. This will help in understanding if there are any barriers to treatment and highlight the best preventive measures, as well as treatment strategies in this population, that might reduce its health burden. CONCLUSION: This will be a pilot study assessing perceptions of PCOS in Kerala, India. If this study demonstrates a low understanding of PCOS as shown in other parts of India, this will provide help in understanding the reasons why the prevalences of PCOS as well as diabetes and infertility, are increasing in the state of Kerala.
