The association between coffee consumption and the risk of type 2 diabetes may vary by genetic variants. Our study addresses the question of whether the incidence of type 2 diabetes is related to the consumption of coffee and whether this relationship is modified by polymorphisms related to type 2 diabetes. We performed a pooled analysis of four Korean prospective studies that included 71,527 participants; median follow-up periods ranged between 2 and 13 years. All participants had completed a validated food-frequency questionnaire (FFQ) at baseline. The odds ratios (ORs) and 95% confidence intervals (CIs) for type 2 diabetes were calculated using logistic regression models. The ORs were combined using a fixed or random effects model depending on the heterogeneity across the studies. Compared with 0 to <0.5 cups/day of coffee consumption, the OR for type 2 diabetes was 0.89 (95% CI: 0.80–0.98, p for trend = 0.01) for ≥3 cups/day of coffee consumption. We did not observe significant interactions by five single nucleotide polymorphisms (SNPs) related to type 2 diabetes (CDKAL1 rs7756992, CDKN2A/B rs10811661, KCNJ11 rs5215, KCNQ1 rs163184, and PEPD rs3786897) in the association between coffee and the risk of type 2 diabetes. We found that coffee consumption was inversely associated with the risk of type 2 diabetes.

Lost To Follow Up

Background/Aims: Youth with type 2 diabetes (T2D) have poor compliance with medical care. This study aimed to determine which demographic and clinical factors differ between youth with T2D who receive care in a pediatric diabetes center versus youth lost to follow-up for >18 months. Methods: Data were analyzed from 496 subjects in the Pe­diatric Diabetes Consortium registry. Enrollment variables were selected a priori and analyzed with univariable and multivariable logistic regression models. Results: After a median of 1.3 years from enrollment, 55% of patients were lost to follow-up. The final model included age, race/ethnicity, parent education, and estimated distance to study site. The odds ratio (99% confidence interval) of loss to follow-up was 2.87 (1.34, 6.16) for those aged 15 to <18 years versus those aged 10 to <13 years and 6.57 (2.67, 16.15) for those aged ≥18 years versus those aged 10 to <13 years. Among patients living more than 50 miles from the clinic, the odds ra tio of loss to follow-up was 3.11 (1.14, 8.49) versus those living within 5 miles of the site. Conclusion: Older adolescents with T2D are more likely to be lost to follow-up, but other socioeconomic factors were not significant predictors of clinic follow-up.

IL-6 levels and polymorphisms have been implicated in type 2 diabetes mellitus (T2DM) and insulin resistance. The IL-6 receptor (IL-6R) comprises two subunits, IL-6R and gp130, of which IL-6R confers specificity to IL-6 action and is located in a region of replicated linkage to T2DM on chromosome 1q21. We screened this gene for variation in Northern European Caucasian and African-American ethnic groups. We identified 11 variants with a minor allele frequency over 5%, including two amino acid changes (D358A and V385I) and four variants in the 3′ untranslated region. No variant was associated with obesity or measures of insulin sensitivity, but two single nucleotide polymorphisms in the 3′ untranslated region showed a trend to an association with T2DM in all Caucasians, and three single nucleotide polymorphisms, including D358A, showed a trend (P &lt; 0.06) to an association with T2DM among the subset of Northern European Caucasians. Variant V385I was unique to African-Americans and was significantly associated with diabetes and diabetic nephropathy (P &lt; 0.05). Among individuals heterozygous for the four variants in the transcribed sequence, one allele was significantly overrepresented, thus suggesting the existence of a regulatory variant controlling mRNA stability or expression. IL-6R is not likely to explain the linkage to diabetes in this region, but our work supports a minor role of variants in T2DM risk and suggests that sequence variants may alter IL-6R mRNA levels and possibly levels of soluble IL-6R.
