The E23K variant of the Kir6.2 gene has been shown to be associated with type 2 diabetes mellitus in Caucasian subjects. Because offspring of type 2 diabetic patients have a genetically increased risk of developing diabetes, we sought to identify the E23K variant of the Kir6.2 gene in offspring of Caribbean patients with type 2 diabetes and assess the contribution of this variant to impaired glucose tolerance in these subjects. Forty-six offspring of patients with type 2 diabetes and 39 apparently healthy subjects whose immediate parents were not diabetic (‘control’) were studied after an overnight fast. Anthropometric indices were measured and blood samples were collected. Fasting and 2 h plasma glucose, insulin and lipids were subsequently determined. Insulin resistance was calculated using the homeostatic model assessment technique. The offspring and control subjects had similar frequencies of the E23K polymorphism (52.6 vs 45.5%, P>0.05) and the frequency of the E23K variant did not differ significantly between gender and ethnic distributions, irrespectively of a family history of diabetes (P>0.05). There were no significant differences in biochemical risk factors for developing diabetes in offspring carriers of the E23K variant compared with offspring non-carriers of the mutation. Offspring with the E23K mutation had even significantly higher 2 h insulin concentrations when compared with control subjects. It is concluded that the presence of the Kir6.2 E23K genotype in Caribbean subjects with an immediate positive family history of diabetes does not confer significantly higher levels of biochemical risk factors for the development of type 2 diabetes.

The prevalence of the metabolic syndrome is highest among Hispanic adults. However, studies exploring the metabolic syndrome in overweight Hispanic youth are lacking. Subjects were 126 overweight children (8–13 yr of age) with a family history for type 2 diabetes. The metabolic syndrome was defined as having at least three of the following: abdominal obesity, low high-density lipoprotein (HDL) cholesterol, hypertriglyceridemia, hypertension, and/or impaired glucose tolerance. Insulin sensitivity was determined by the frequently sampled iv glucose tolerance test and minimal modeling. The prevalence of abdominal obesity, low HDL cholesterol, hypertriglyceridemia, systolic and diastolic hypertension, and impaired glucose tolerance was 62, 67, 26, 22, 4, and 27%, respectively. The presence of zero, one, two, or three or more features of the metabolic syndrome was 9, 22, 38, and 30%, respectively. After controlling for body composition, insulin sensitivity was positively related to HDL cholesterol (P < 0.01) and negatively related to triglycerides (P < 0.001) and systolic (P < 0.01) and diastolic blood pressure (P < 0.05). Insulin sensitivity significantly decreased (P < 0.001) as the number of features of the metabolic syndrome increased. In conclusion, overweight Hispanic youth with a family history for type 2 diabetes are at increased risk for cardiovascular disease and type 2 diabetes, and this appears to be due to decreased insulin sensitivity. Improving insulin resistance may be crucial for the prevention of chronic disease in this at-risk population.

Objective: To evaluate the prevalence of newly diagnosed prediabetes, diabetes mellitus among the officers from Phuoc Long district of Binh Phuoc province. Subjects and methods: 268 personals communications service was examined the impaired fasting glucose (G0); impaired glucose tolerance (G2) anh HbA1c. Results: Prevalence of prediabetes, type 2 diabetes mellitus by G0, G2, HbA1c as follows 16,0%; 13,1%; 17,9% and 3,8%; 6,7%; 2,2%. Common prevalence of prediabetes in 26,9%; type 2 diabetes mellitus in 7,1%. Conclusion: Personal communications service from Phuoc Long district have percentage of prediabetes higher compared to type 2 diabetes mellitus which of prediabetes was diagnosed by HbA1c which takes up the highest percentage; diabetes mellitus was diagnosed by G2which takes up the highest percentage.
