Topics in Clinical Nutrition: January/March 2020 - Volume 35 - Issue 1 - p 71–90 doi: 10.1097/TIN.0000000000000196 Buy Metrics Abstract Polycystic ovary syndrome (PCOS) affects approximately 0.76% to 3% of adolescent females. The Academy of Nutrition and Dietetics' Nutrition Care Manual includes evidence-based medical nutrition therapy guidelines for PCOS. This review compiled lifestyle considerations for adolescents and young adults (≤24 years) with PCOS and evaluated the efficacy of the Academy's guidelines for this subgroup. Findings suggest that registered dietitian nutritionists counseling adolescents and young adults with PCOS follow the Nutrition Care Manual recommendations for women of reproductive age. However, the literature also supports special considerations for assessing, counseling/educating, and monitoring adolescents and young women, which are summarized for clinicians.
