| We examine the effects of metformin on insulin resistance (IR) and mood including in adolescent and
adult women with polycystic ovary syndrome (PCOS). This trial was conducted in 19 adolescents (age
18 years) and 25 adult (age >18 years) women with PCOS. Anthropometric and measurements including,
serum glucose, endocrine panel, and lipid profile were performed at baseline. IR was measured by
Homeostasis Model Assessment IR (HOMA-IR). Anxiety and depression were measured by Beck’s Anxiety
(BAI) and Depression Inventories (BDI-II). All tests were repeated after a 90-day treatment with metformin
(1,500mg/day). The severity of depression and anxiety decreased after 90-day treatment with metformin
in women diagnosed with PCOS. The BAI scores were higher in adolescent group while BDI-II scores were
higher in the adult group (p¼.016). After 90-day metformin treatment, both BDI-II and BAI scores were
decreased by 3.3 and 3.4, respectively (p<.001). Indicators of IR and obesity were improved with this
therapy. Although the adolescents weighed lower than the adults, baseline HOMA-IR 5.5 ± 1.7 was higher
in this group than 4.4 ± 1.2 in the adult women (p =.022). The findings suggest that metformin decrease
IR and improve mood both in adolescent and adult women with PCOS. |
