Correlations between impulsiveness and biochemical parameters in women with polycystic ovary syndrome

Objective: The aim of this study was to investigate the relationship between anger, impulsiveness, and biochemical parameters (testosterone, insulin, insulin resistance) in women with polycystic ovary syndrome. Study design: We recruited 84 women diagnosed with polycystic ovary syndrome according to the Rotterdam diagnostic criteria. Psychiatric interviews were performed using the Structured Clinical Interview for DSM-IV Axis I Disorders. The Barratt Impulsiveness Scale and the State Trait Anger Expression Inventory were also administered to each participant. Lastly, the women's biochemical parameters, which included total testosterone, free androgen index, dehydroepiandrosterone sulfate, insulin and insulin resistance, thyroid functions, and prolactin, were measured. Results: A statistically significant correlation was found between participants' increasing total testosterone levels and total impulsiveness scores, and their increasing free androgen index levels and motor and non-planning-related impulsiveness (r = 0.24, p = 0.027; r = 0.27, p = 0.015; and r =0.26, p = 0.017, respectively). High insulin and insulin resistance levels were associated with high non planning-related impulsiveness scores (r= 0.26, p=0.018; and r = 0.26, p = 0.019). Lastly, high trait anger and anger expression scores were related to high total testosterone and insulin and insulin resistance levels. Conclusion: Androgens and glucose dysregulation seemingly affect anger expression as well as the attentional, motor, and non-planning-related impulsiveness of women with polycystic ovary syndrome.
