Coffee consumption has been inversely associated with type 2 diabetes risk, but its mechanisms are largely unknown. We aimed to examine whether plasma levels of sex hormones and sex hormone—binding globulin SHBG may account for the inverse association between coffee consumption and type 2 diabetes risk. We conducted a case-control study nested in the prospective Women's Health Study WHS. During a median follow-up of 10 years, postmenopausal women with newly diagnosed type 2 diabetes were matched with control subjects by age, race, duration of follow-up, and time of blood draw. Caffeinated coffee was positively associated with SHBG but not with sex hormones. Multivariable-adjusted geometric mean levels of SHBG were In contrast, neither decaffeinated coffee nor tea was associated with SHBG or sex hormones. The association was largely attenuated after further adjusting for SHBG OR 0. Our findings suggest that SHBG may account for the inverse association between coffee consumption and type 2 diabetes risk among postmenopausal women. Previous prospective studies have documented an inverse association between coffee consumption and type 2 diabetes risk 12especially in women 2. Coffee intake may improve glucose tolerance via activation of energy metabolism and enhancement of insulin sensitivity and β-cell function 23 —although much of the molecular mechanism remains unknown. Previous cross-sectional studies have associated coffee intake with plasma levels of sex hormones or sex hormone—binding globulin SHBG 45. In addition, a large body of observational and experimental data has implicated the important roles of sex hormones in the development カフェ イン セックス type 2 diabetes 6 — 8. Notably, recent experiments indicate that SHBG not only regulates the biologically active fraction of sex hormones but may bind to its own receptors at the plasma membranes of a variety of cells, directly mediating intracellular signaling of sex hormones 9. More recently, prospective studies of men and women incorporating both genetic and phenotypic assessment of SHBG revealed a strong inverse association between SHBG levels and type 2 diabetes risk However, no studies have comprehensively evaluated the interrelationships of coffee consumption in relation to sex hormones and SHBG with respect to type 2 diabetes risk. To examine whether and to what extent sex hormones or SHBG may account for the potential カフェ イン セックス effect of coffee intake against type 2 diabetes, we analyzed data from a prospective case-control study of women. In particular, we evaluated the associations of coffee consumption with plasma levels of sex hormones and SHBG, as well as the direct association between coffee consumption and type 2 diabetes risk during a year follow-up. Moreover, we investigated whether the association of coffee consumption with type 2 diabetes risk was attenuated by further adjusting for plasma sex hormones or SHBG. Finally, we examined whether coffee intake may interact with specific SHBG genotypes in affecting diabetes risk. The Women's Health Study WHS is a randomized, double-blind, placebo-controlled trial originally designed to evaluate the balance of benefits and risks of low-dose aspirin and vitamin E in the primary prevention of cardiovascular disease and cancer At baseline, participants were asked if they were willing カフェ イン セックス provide blood samples by mail. Women who responded affirmatively and were eligible to be enrolled into the run-in phase were mailed a blood collection kit. By Februaryof these initially healthy women reported developing incident type 2 diabetes. Based on these eligibility criteria, case subjects and control subjects were included in our analyses. Written informed consent was obtained from all participants. This study was approved by the Institutional Review Boards of Brigham and Women's Hospital, Harvard Medical School, and the University of California, Los Angeles UCLA. Using U. カフェ イン セックス of Agriculture food composition data supplemented with other sources, we estimated that the caffeine content was mg per cup of coffee, 47 mg per cup of tea, 46 mg per bottle or can of cola beverage, and 7 mg per serving of chocolate candy カフェ イン セックス Details regarding ascertainment of incident type 2 diabetes in our cohorts have been reported previously After excluding those with diabetes at baseline, all participants were asked annually whether and when they had a diagnosis of diabetes since baseline. Using the diagnostic criteria of the American Diabetes Association 15all self-reported cases of type 2 diabetes were confirmed by a supplemental questionnaire.
