By combining genome-wide association data from 8,130 individuals with type 2 diabetes (T2D) and 38,987 controls of European descent and following up previously unidentified meta-analysis signals in a further 34,412 cases and 59,925 controls, we identified 12 new T2D association signals with combined P<5x10(-8). These include a second independent signal at(More)
Type 2 diabetes (T2D) can be prevented in pre-diabetic individuals with impaired glucose tolerance (IGT). Here, we have used a metabolomics approach to identify candidate biomarkers of pre-diabetes. We quantified 140 metabolites for 4297 fasting serum samples in the population-based Cooperative Health Research in the Region of Augsburg (KORA) cohort. Our(More)
CONTEXT AND OBJECTIVE A growing body of evidence suggests that vitamin D deficiency may adversely affect the cardiovascular system. Therefore, we thought to prospectively assess the association between serum 25-hydroxyvitamin D, the most commonly used index of vitamin D status, and incident coronary heart disease. DESIGN, SETTING, AND PATIENTS We measured(More)
The genetic architecture of common traits, including the number, frequency, and effect sizes of inherited variants that contribute to individual risk, has been long debated. Genome-wide association studies have identified scores of common variants associated with type 2 diabetes, but in aggregate, these explain only a fraction of the heritability of this(More)
OBJECTIVE The American Diabetes Association (ADA) has recently recommended HbA1c for diagnosing diabetes as an alternative to glucose-based criteria. We compared the new HbA1c-based criteria for diagnosis of diabetes and prediabetes with the glucose-based criteria. RESEARCH DESIGN AND METHODS In the population-based German KORA surveys (S4/F4) 1,764(More)
OBJECTIVES To evaluate the association of posttraumatic stress disorder (PTSD) with type 2 diabetes (T2D) or prediabetes in a large population-based sample. METHODS In 2970 subjects (aged 32-81 years) drawn from the population-based cross-sectional study KORA F4 from the Augsburg region (Southern Germany) a PTSD screening was performed employing the(More)
OBJECTIVE The metabolic syndrome is a major public health challenge and identifies persons at risk for diabetes and cardiovascular disease. The aim of this study was to examine the association between age at menarche and the metabolic syndrome (IDF and NCEP ATP III classification) and its components. DESIGN 1536 women aged 32 to 81 years of the German(More)
The objective of the present study was to identify external, intrinsic or behavioural factors that significantly influenced serum 25-hydroxyvitamin D (25(OH)D) concentrations in a German survey. Data from 3061 participants in the Cooperative Health Research in the Region of Augsburg, Germany (KORA) F4 survey were used to relate potential determinants to(More)
OBJECTIVE To assess the association between serum 25-hydroxyvitamin D (25-OHD) and incident type 2 diabetes and to determine whether the association is mediated by subclinical inflammation. RESEARCH DESIGN AND METHODS Using a case-cohort design, baseline levels of 25-OHD were measured in 416 case subjects with incident type 2 diabetes and 1,267 noncase(More)
