Objectives: This study examines the roles of hyperandrogenism (HA) and insulin resistance (IR) in eating behaviors among adolescents with polycystic ovary syndrome (PCOS). Methods: Fifty adolescents with PCOS (mean age 16.04 +/- 1.46 years, BMI 27.55 +/- 6.34) were assessed. IR was evaluated using HOMA-IR, and eating behaviors were measured with the Eating Attitudes Test (EAT) and the Eating Disorders Examination Questionnaire (EDE-Q). Results: IR was present in 46 % of participants, with obesity affecting 71 % of those with IR. While EAT scores showed no significant association with BMI, HA, or IR, the IR group had higher EDE-Q Total scores (p=0.05), particularly in Shape Concern (SC, p=0.003) and Weight Concern (WC, p=0.03). HA primarily influenced WC (p=0.04). BMI correlated more strongly with WC (r=0.579, p<0.001) than IR. ROC analysis indicated BMI>27.5 (AUC=0.967) and HOMA-IR>3.1 (AUC=0.961) as strong predictors of disordered eating. Conclusions: BMI and HOMA-IR are more reliable than HA for identifying disordered eating behaviors in PCOS adolescents. The EDE-Q is recommended for effective screening, emphasizing the need to monitor BMI and HOMA-IR in this population.
