Abstract

Background: The aim of the present study was to evaluate the beneficial effects of chromium intake on markers of insulin metabolism and lipid profiles in women with polycystic ovary syndrome (PCOS). Methods: In a prospective, randomized, double-blind, placebo-controlled trial, 64 women with PCOS were randomized to receive 200 µg chromium picolinate supplements (n = 32) or placebo (n = 32) for 8 weeks. Fasting blood samples were obtained at baseline and 8 weeks after the intervention to quantify markers of insulin metabolism and lipid concentrations. Results: Chromium supplementation in women with PCOS resulted in significant decreases in serum insulin levels (-3.6 ± 7.4 vs. +3.6 ± 6.2 µIU/ml, p < 0.001), homeostasis model of assessment-insulin resistance (HOMA-IR; -0.8 ± 1.6 vs. +0.9 ± 1.5, p < 0.001), homeostatic model assessment-beta cell function (HOMA-B; -15.5 ± 32.3 vs. +13.6 ± 23.1, p < 0.001), and a significant increase in quantitative insulin sensitivity check index (QUICKI) score (+0.02 ± 0.03 vs. -0.008 ± 0.02, p = 0.001) compared with the placebo. In addition, a trend toward a significant effect of chromium supplementation on decreasing serum triglycerides (-12.4 ± 74.4 vs. +15.2 ± 32.4 mg/dl, p = 0.05), very low-density lipoprotein-cholesterol (-2.5 ± 14.9 vs. +3.0 ± 6.5 mg/dl, p = 0.05), and cholesterol concentrations (-8.6 ± 21.9 vs. +0.7 ± 22.4 mg/dl, p = 0.09) was seen. Conclusions: Eight weeks of chromium supplementation among PCOS women had favorable effects on markers of insulin metabolism.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
