In 2005, it was estimated that more than 20 million people in the United States had diabetes. Approximately 30% of these people had undiagnosed cases. Increased risk for diabetes is primarily associated with age, ethnicity, family history of diabetes, smoking, obesity, and physical inactivity. Diabetes-related complications--including cardiovascular disease, kidney disease, neuropathy, blindness, and lower-extremity amputation--are a significant cause of increased morbidity and mortality among people with diabetes, and result in a heavy economic burden on the US health care system. With advances in treatment for diabetes and its associated complications, people with diabetes are living longer with their condition. This longer life span will contribute to further increases in the morbidity associated with diabetes, primarily in elderly people and in minority racial or ethnic groups. In 2050, the number of people in the United States with diagnosed diabetes is estimated to grow to 48.3 million. RESULTS: from randomized controlled trials provide evidence that intensive lifestyle interventions can prevent or delay the onset of diabetes in high-risk individuals. In addition, adequate and sustained control of blood sugar levels, blood pressure, and blood lipid levels can prevent or delay the onset of diabetes-related complications in people with diabetes. Effective interventions, at both the individual and population levels, are desperately needed to slow the diabetes epidemic and reduce diabetes-related complications in the United States. This report describes the current diabetes epidemic and the health and economic impact of diabetes complications on individuals and on the health care system. The report also provides suggestions by which the epidemic can be curbed.

    ABSTRACT: Aims: Studies have shown that diabetes mellitus disproportionately afflicts persons of low socioeconomic status and that the burden of disease is greatest among the disadvantaged. However, our understanding of educational differences in the control of diabetes and its impact on survival is limited. This study investigated the associations among education, hemoglobin A1c (HbA1c), and subsequent mortality in adults with diabetes. Methods: Prospective cohort data from the 2006, 2008, and 2010 Health and Retirement Study were linked with biomarker data for U.S. older adults with diabetes (n=3312). Weighted distributions were estimated for all subjects at baseline and by the American Diabetes Association's general guidelines for HbA1c control (<7.0% [53 mmol/mol] vs. ≥7.0% [53 mmol/mol]). Proportional hazard models were used to estimate educational differences in all-cause mortality by HbA1c level with sequential adjustments for contributing risk factors. Results: Mortality risks associated with HbA1c≥7.0% [53 mmol/mol] were significantly greater in lower-educated adults than higher-educated adults (P<0.001). We found that the hazard ratios (HR) associated with HbA1c ≥7.0% [53 mmol/mol] were highest among low-educated adults (HR=2.18, 95% CI: 1.62, 2.94) and that a combination of socioeconomic, psychosocial, and behavioral factors accounted for most, but not all, of the associations. Conclusions: Educational differences in HbA1c control have significant implications for mortality and efforts to reduce these disparities should involve more vigilant screening and monitoring of lower-educated adults with diabetes.

    ABSTRACT: Objective: The main objective of this study was to estimate the annual direct healthcare cost of type 2 diabetes mellitus healthcare and its complications in Lithuanian population. Material and methods: The study uses a prevalence-based top-down approach. The random sample of study participants was formed using the database of the National Health Insurance Fund under the Lithuanian Ministry of Health. 762 patients with diabetes mellitus type 2 data were analyzed in this research. The data on healthcare costs was recorded between January 1, 2011 and December 31, 2011. Results: Ambulatory care cost mean per patients with diabetes mellitus type 2 in 2011 was EUR 156.14 (95% CI, 147.05-165.24). 34.4% patients had at least one hospitalization during the 2011 year. Mean annual cost per patients of hospitalization was EUR 1160.16 (95% CI, 1019.60-1300.73). Covered drugs and diabetes supplies annual direct cost mean per patients was EUR 448.34 (95% CI, 411.14-485.54). The more expensive treatment was with oral and non-insulin injectable hypoglycemic medications (P<0.001). 65.1% participants were diagnosed one or more diabetes-related chronic complications. Average annual cost per person, increased gradually with the numbers of complications from EUR 671.94 (95% CI, 575.03-768.86) in patients without complications to EUR 1588.98 (95% CI, 1052.09-2125.86) in patients with 3 and more complications (P<0.001). Conclusions: The largest part of direct costs in diabetes mellitus healthcare composes hospital inpatient care and covered drugs expenditures. In our study we observed that the presence of microvascular, macrovascular chronic complication increased the direct cost per patient, compared with patients without complications.

    • "Type 2 diabetes is a major risk factor for vascular disease with 65% of all diabetic deaths being due to cardiovascular disease [1]. Lifestyle characteristics, such as physical activity, diet, and stress are important factors that influence development and prognosis of type 2 diabetes [2]. Changes in diet and increase in physical activity (walking, etc.) and exercise (running, cycling, etc.) are key components of the management of type 2 diabetes [3], and guidelines recommend changes in these lifestyle characteristics for both prevention and management of the disease [4].

    ABSTRACT: Objective: The effect of lifestyle intervention on clinical risk factors in patients with type 2 diabetes is unclear. The aim of this meta-analysis was to evaluate the effects of comprehensive lifestyle change, such as diet, exercise, and education, on clinical markers that are risk-factors for cardiovascular disease in patients with type 2 diabetes. Methods: We searched Medline, Cochrane, EMBASE, and Google Scholar (up to August 31, 2013) for randomized controlled trials that compared standard of care (control group) with treatment regimens that included changes in lifestyle (intervention group). The primary outcome was reduction in risk factors of cardiovascular disease including body mass index (BMI), glycated hemoglobin (HbA1c), systolic blood pressure (SBP), diastolic blood pressure (DBP), high-density lipoprotein cholesterol (HDL-c), and low-density lipoprotein cholesterol (LDL-c). Results: A total of 16 studies were included in the meta-analysis. The standardized difference in means of change from baseline significantly favored the intervention compared with the control group in BMI (-0.29; 95% CI, -0.52 to -0.06, P=0.014), HbA1c (-0.37; 95% CI, -0.59 to -0.14, P=0.001), SBP (-0.16: 95% CI, -0.29 to -0.03, P=0.016), DBP (-0.27, 95% CI=-0.41 to -0.12, P<0.001). There was no difference between the intervention and control groups in HDL-c (0.05; 95% CI, -0.10 to 0.21; P=0.503) and LDL-c (-0.14; 95% CI, -0.29 to 0.02; P=0.092). Conclusions: The meta-analysis found that lifestyle intervention showed significant benefit in risk factors that are known to be associated with development of cardiovascular disease in patients with type 2 diabetes.
