Bisphenol A is related to circulating levels of adiponectin, leptin and ghrelin, but not to fat mass or fat distribution in humans

• Objective: Since bisphenol A (BPA) has been shown to induce obesity in experimental studies, we explored the associations between BPA and fat mass, fat distribution and circulating levels of adiponectin, leptin and ghrelin in humans. Methods: In the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS), fat mass and fat distribution were determined in 70-year-old men and women (n = 890) by dual-energy X-ray absorptiometry (DXA) and magnetic resonance imaging (MRI) (n = 287). Serum levels of BPA were analyzed using isotope liquid chromatography/tandem mass spectrometer (API4000LC-MS/MS). Hormone levels were analyzed with radioimmunoassays (RIA) or enzyme-linked immunosorbent assay (ELISA). Imaging was performed approximately two years following collection of other data. Results: Serum concentrations of BPA were not related to adipose tissue measurements by DXA or MRI. BPA associated positively with adiponectin and leptin, but negatively with ghrelin, following adjustments for sex, height, fat mass, lean mass, smoking, alcohol consumption, physical activity, energy intake, and educational levels (p < 0.001, p = 0.009, p < 0.001, respectively). The relationship between BPA and ghrelin was stronger in women than in men. Conclusion: Although no relationships between BPA levels and measures of fat mass were seen, BPA associated strongly with the adipokines adiponectin and leptin and with the gut-hormone ghrelin suggesting that BPA may interfere with hormonal control of hunger and satiety.
