Barriers to Prevention and Treatment of Type 2 Diabetes Mellitus Among Outpatients in Belarus.

Objectives: This study aimed to determine the main barriers and reasons for non-adherence to preventive measures and treatment for type 2 diabetes mellitus among outpatients in Belarus. Methods: An anonymous questionnaire survey was conducted with 814 adults aged 18 years and over who visited outpatient health care units and hospitals in Belarus. The questionnaire was developed to analyze the perceived barriers that limit adherence to preventive measures and treatment for type 2 diabetes. Results: The proportion of respondents who reported doing daily physical activity was 53.2%, and 46.6% consumed at least 400 grams of fruit and vegetables per day. Among the 42.8% of respondents with a prescribed treatment for type 2 diabetes mellitus, 50.1% sometimes forgot to take their medicine. The specific barriers to treatment most frequently identified by survey respondents were "Financial situation" (23.5% of respondents), and "Fear of side effects" (25.2%). Those for lifestyle instructions were "Insufficient knowledge" (29.3%), "Financial situation" (27.9%), and "Lack of motivation" (21.7%). Conclusions: The study revealed that the main barriers to adherence were insufficient knowledge of diabetes and its treatment and an underestimation of the role of behavioral risk factors in health, combined with financial difficulties. We recommend that physicians should take a patient-centered approach to raising awareness of behavioral risk factors for type 2 diabetes mellitus, and suggest that the importance of adhering to preventative measures and treatment should be promoted in consultations in Belarus.

Leptin is an independent determinant of bone mineral density in men with type 2 diabetes mellitus.

To investigate the possible relationship of leptin to bone mineral density (BMD) in men with type 2 diabetes mellitus (T2DM), we screened 168 Belarusian men aged 45-65 years. Plasma total cholesterol (TC), high-density lipoprotein cholesterol, and triglyceride concentrations were assessed, and low-density lipoprotein cholesterol and very low-density lipoprotein cholesterol (LDL-C) were calculated. Hemoglobin A(1c), immune-reactive insulin (IRI), serum total testosterone, and sex hormone-binding globulin were also evaluated. BMD was evaluated using dual-energy X-ray absorptiometry. By univariate linear regression analysis, BMD was significantly correlated with body mass index (r = 0.23, P = 0.002) and leptin (r = 0.21, P = 0.006). By multivariate regression analysis adjusting for confounding factors, log leptin was independently correlated with BMD (ß = 0.058, P = 0.001). Our study revealed that leptin is an independent determinant of BMD in patients with T2DM. Further research is necessary to confirm this association and to develop ways to correct abnormalities of bone metabolism in patients with T2DM.

Testosterone is an independent determinant of bone mineral density in men with type 2 diabetes mellitus.

BACKGROUND: Although many reports have elucidated pathophysiological characteristics of abnormal bone metabolism in patients with type 2 diabetes mellitus (DT2), determinants of bone mineral density (BMD) in patients with DT2 are still controversial. METHODS: We examined 168 Belarussian men 45-60 years of age. Plasma total cholesterol (TC), high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, very low-density lipoprotein cholesterol, triglycerides, hemoglobin A(1c) (HbA(1c)), immunoreactive insulin, and C-reactive protein concentrations were assessed. BMD was measured using dual energy X-ray densitometry of the lumbar spine (L(1)-L(4)). Total testosterone (TT) and sex hormone-binding globulin were measured, and free testosterone (FT) was calculated. RESULTS: Using univariate linear regression analysis, BMD of the lumbar spine was significantly correlated with FT (r=0.32, p<0.01) and TT (r=0.36, p<0.01). Using multiple linear regression analysis adjusted for confounding factors, BMD was significantly correlated with TT (ß=0.23, p<0.001) and TC (ß=-0.029, p=0.005). Age (ß=0.005, p=0.071), body mass index (ß=0.005, p=0.053), HbA(1c) (ß=-0.002, p=0.72) and duration of diabetes (ß=0.001, p=0.62) were not significantly correlated with BMD. CONCLUSIONS: Our data indicate that androgens are independent determinants of BMD in male patients with DT2.
