OBJECTIVES: This study aimed to evaluate the Standardized Mean Difference (SMD) of insulin resistance parameters in women with IH, compared to healthy and polycystic ovary syndrome (PCOS) controls.
MATERIALS AND METHODS: PubMed, Scopus, Web of Sciences, and Embase were searched for retrieving studies published up to November 2021 investigating the insulin resistance parameters in women with IH, compared to control groups. Meta-regression and subgroup analysis were conducted to evaluate the effect of potential confounders, such as age, BMI, and study design.
RESULTS: A meta-analysis of 20 studies revealed that higher SMDs of fasting insulin (SMD: 0.58; 95% CI: 0.10, 1.06), HOMA-IR (SMD: 0.53; 95% CI: 0.09, 0.97), and FBS levels (SMD: 0.11; 95% CI: 0.03, 0.19) in women with IH than healthy. It also showed that the SMD of HOMA-IR was significantly lower in women with IH than PCOS patients (SMD: -0.49; 95% CI: -0.88, -0.09). A subgroup analysis of cross-sectional studies showed higher SMDs of fasting insulin (SMD: 0.86; 95% CI: 0.05, 1.68), HOMA-IR (SMD: 0.83; 95% CI: 0.01, 1.64), and FBS levels (SMD: 0.14; 95% CI: 0.00, 0.28) in women with IH than healthy, whereas there was no difference in the SMD of these metabolic parameters between IH and PCOS groups, except for SMD of HOMA-IR (SMD: -0.22; 95% CI: -0.42, -0.02).
CONCLUSIONS: The results of the study demonstrate that insulin resistance parameters are related to IH, although insulin resistance values in women with IH are not as high as in patients with PCOS. According to the results of the study, measuring these metabolic parameters can be beneficial to evaluate all hirsute women with IH.
