The Effect of Chromium Supplementation on Polycystic Ovary Syndrome in Adolescents

Background: Polycystic ovary syndrome (PCOS) is a common condition. Treatment with chromium has been shown, to improve insulin sensitivity in adults with PCOS. Treatment of adolescents with PCOS remains a challenge. Objective: To investigate the effect of chromium supplementation on the various components of polycystic ovary syndrome in adolescent girls. Patients and Methods: Thirty-five adolescent girls with PCOS were enrolled. History of menstrual irregularities was recorded. All underwent physical examination for presence of acne, scoring of hirsutism, and calculation of body mass index. Pelvic ultrasonography was done and serum free testosterone was measured in all subjects. All subjects received 1000 mu g chromium picolinate for 6 months followed by re-evaluation. Results: Mean (SD) age was 15.5 (1) years (range: 14-17 y). No significant change in BMI standard deviation score (SOS) with chromium supplementation was noted (1.9 (0.7) SDS vs 2 (0.7) SDS, P = .638). The number of patients with oligo/amenorrhea decreased with treatment (29/35 (83%) versus 11/35 (31%), P < .001). Significant reduction in mean ovarian volume (P < .001), total follicular count (P < .034), and free testosterone (P < .002) was observed. No significant improvement in acne or hirsutim was noted. Conclusion: Supplementation with chromium to adolescents with PCOS is a promising treatment option.
