Introduction:Polycystic ovary syndrome (PCOS) is the most common endocrine abnormality affecting women of reproductive age, but this condition is still not completely understood. As it is linked with many chronic conditions such as cardiovascular and diabetes, there is need to identify the condition at the earliest. Methods: A cross-sectional Community-based study was conducted in urban Visakhapatnam in November 2020 among 132 adolescent girls aged between 15 to 19 years to study the prevalence of PCOS among adolescents to identify the risk factors for polycystic ovarian syndrome. Multistage sampling was used to select the study participants from six urban zones, information collected using a PCOS validated questionnaire modified to suit locally. Diagnosis of PCOS was based on Rotterdam/ESHRE criteria examination for obesity, hirsutism, acne and acanthosis. Results: Six percentof the study subjects were found to have possible diagnosis of PCOS. Family history of risk factors for PCOS such as maternal menstrual irregularities, diabetes and obesity was found in 12.1% of study subjects.Increased BMI was seen in 6.8% girls and 24 .1% had abnormal menstruation.
