Background: In 35 adolescent females (17 ± 2 years) with polycystic ovary syndrome (PCOS), median body mass index (BMI) 30.8 kg/m2, we assessed effeicacy of metformin-diet for 1 year for reduction of weight, insulin, HOMA insulin resistance (IR), cholesterol, triglycerides, and resumption of regular menses. Methods: Calories (26% protein, 44% carbohydrate) were targeted to 1,500-1,800/day if BMI was <25 or to 1,200-1,500/day if BMI was ≥25, along with 2,550 mg metformin. Results: Median weight fell from 82.7 to 79.1 kg (p = 0.009), insulin 16.7 to 13.3 μU/ml (p <0.0001), HOMA IR 3.41 to 2.74 (p = 0.0004), total cholesterol 164 to 151 mg/dl (p = 0.002), and triglyceride 103 to 85 mg/dl (p = 0.006). The percentage of cycles with normal menses rose from a pre-treatment mean of 22% to 74%, p < 0.0001. Conclusions: In adolescents with PCOS, metformin-diet reduces weight, insulin, IR, cholesterol, and triglycerides, and facilitates resumption of regular menses.
