- Background: Diabetes is associated with increased risk of a spectrum of cancers, but there are few meta-analyses on the association between diabetes and kidney cancer. We performed a meta-analysis of case-control studies and cohort studies to address the incidence and mortality of kidney cancer in diabetes. Methods: Studies were identified by searching PubMed database and manual assessment of the cited references in the retrieved articles. Study-specific relative risks (RRs) and 95% confidence intervals (CIs) were estimated using a random-effect model. Study quality was assessed using the Newcastle-Ottawa scale. Results: A total of 24 studies were included. We found that diabetes was significantly associated with increased risk of kidney cancer (RR=1.40, 95% CI = 1.16 to 1.69), and the results were consistent between case-control and cohort studies. A slightly stronger positive relation was observed in women (RR = 1.47, 95% CI=1.18 to 1.83) than in men (RR=1.28, 95% CI=1.10 to 1.48). Additional analyses indicated that the increased risk of kidney cancer was independent of alcohol consumption, body mass index (BMI)/obesity and smoking. However, there was no association between diabetes and mortality of kidney cancer (RR=1.12, 95% CI=0.99 to 1.20), without heterogeneity (P = 0.419, I-2 = 1.8%). Conclusions: Diabetes mellitus may increase the risk of kidney cancer in both women and men.

- OBJECTIVE: Data on latent autoimmune diabetes in adults (LADA) from population-based studies are sparse. We sought to investigate the prevalence and correlates of LADA. RESEARCH DESIGN AND METHODS: A total of 8,109 participants, who were aged >= 15 years and living in Tianjin, China, were assessed to identify individuals with type 2 diabetes (American Diabetes Association Criteria, 1997) and further to detect patients with LADA. LADA was ascertained by 1) the presence of type 2 diabetes and age >= 35 years, 2) the lack of a requirement for insulin at least 6 months after the diagnosis of type 2 diabetes, and 3) serum GAD antibody positivity. Data were analyzed using multinomial logistic regression with adjustment for potential confounders. RESULTS: Of all participants, 498 (6.1%) were patients with type 2 diabetes. Of them, 46 (9.2%) were found to have LADA. The prevalence of LADA was 0.6% (46 of 8,109), and tended to increase with age up to 50-59 years in all participants. The odds ratios (95% CI) of LADA related to hypertension, family history of diabetes, waist-to-hip ratio >= 0.85, and major stressful events were 1.93 (1.02-3.65), 17.59 (9.08-34.06), 5.37 (2.31-12.49), and 4.09 (1.75-9.52), respectively. CONCLUSIONS: The prevalence of LADA is similar to 9% in patients with type 2 diabetes. Hypertension, family history of diabetes, central obesity, and major stressful events may be associated with the occurrence of LADA.

Detection of Prediabetes and Undiagnosed Type 2 Diabetes : A Large Population-Based Study
- 2012

Journal article (peer-reviewed)abstract
- Objective: Prediabetes and undiagnosed diabetes have been commonly ignored. We aimed to investigate the prevalence of prediabetes and undiagnosed type 2 diabetes mellitus, and to verify the hypothesis that vascular risk factors (VRFs) may indicate prediabetes and undiagnosed type 2 diabetes.Methods: A total of 7567 adults, who were 20 to 79 years of age, and living in Tianjin, China, participated in this study. Type 2 diabetes was assessed based on medical history, hypoglycemic drugs use, fasting plasma glucose level >= 7.0 mmol/L, or postprandial 2-hour plasma glucose level >= 11.1 mmol/L. Undiagnosed type 2 diabetes was defined among subjects with type 2 diabetes when neither a medical history of diabetes nor hypoglycemic drugs use was present. Prediabetes was ascertained as fasting plasma glucose level of 6.1 to 6.9 mmol/L, or postprandial 2-hour plasma glucose level of 7.8 to 11.0 mmol/L (WHO 1999) among diabetes-free participants. Data were analyzed using multinomial logistic regression with adjustment for potential confounders.Results: Of all participants, 655 (8.7%) had prediabetes, and 721 (9.5%) were patients with type 2 diabetes, including 321 (4.2%) undiagnosed type 2 diabetes accounting for 44.5% patients with diabetes. The prevalence of prediabetes and undiagnosed type 2 diabetes increased with age, and was higher in women than in men. In a fully adjusted multinomial logistic regression model, hypertension, overweight, obesity, central obesity, and family history of diabetes were significantly associated with prediabetes and undiagnosed diabetes, whereas physical inactivity was independently related to undiagnosed diabetes.Conclusion: The prevalence of prediabetes and undiagnosed diabetes is approximately 13%, and almost 45% of patients with diabetes are undiagnosed. VRFs, such as hypertension, high adiposity, and family history of diabetes can be indicators for detecting prediabetes and undiagnosed diabetes.
