Abstract
Objectives: The study aimed to assess the associations between circulating vaspin levels and nutritional status (assessed
on tha basis of BMI) as well as insulin resistance in PCOS.
Material and methods: Eighty-seven PCOS women, 48 obese and 39 normal weight, were enrolled in the cross-sectional
study. Seventy-two Non-PCOS women, 41 obese and 31 normal weight, constituted a control group. Body mass, height and
waist circumference as well as body composition by bioimpedance were measured. In the morning (16h after the last meal)
we determined: serum glucose, insulin, androgens, gonadotropin (LH, FSH) and sex hormone-binding globulin (SHBG) as
well as plasma vaspin levels. Standard HOMA-IR formula was used to assess insulin resistance (IR).
Results: Plasma vaspin levels were significantly lower in PCOS, both normal weight and obese, than in Non-PCOS
groups. Vaspin levels were similar in normal weight and obese PCOS subgroups. There was no association between plasma
vaspin levels and anthropometric parameters in PCOS group. While in Non-PCOS group a negative correlation between
plasma vaspin levels and body mass (r = –0.26; p < 0.05) was found. We did not observe correlations between plasma vaspin
levels and serum glucose and insulin concentrations as well as HOMA-IR values, however, in multivariable, stepwise backward
regression waist circumference and HOMA-IR values explained 18.0% of plasma vaspin levels variability in the study subjects.
Conclusions: PCOS occurrence is associated with decreased vaspin levels. The influence of nutritional status on vaspin level
observed in Non-PCOS is abolished in PCOS women, possibly by more severe insulin resistance.
