Rising Burden of Obesity in Asia

Overweight and obesity have reached epidemic proportions in many Asian countries. These countries also face a grave burden of obesity-related disorders such as diabetes, hypertension, and cardiovascular diseases, which develop at a younger age than in Western populations. These disorders are also manifested in childhood. The major causative factors are related to the lifestyle changes occurring due to rapid socioeconomic transition. Asian populations show several differences in genetic factors when compared with the white population, and they also have lower cut points for environmental risk factors. National programmes targeting public awareness, education and improved structural facilities to facilitate healthy lifestyle are the keys to alleviate the economic and health care burden of the obesity-related disorders

Assessment of lower leg muscle force distribution during isometric ankle dorsi and plantar flexion in patients with diabetes: a preliminary study.

AIM The aim of this study was to evaluate the differences in ankle muscle strength using hand-held dynamometry and to assess difference in the isometric muscle force distribution between the people with diabetes and control participants. METHODS The maximal muscle strength of ankle plantarflexion, dorsiflexion, eversion, inversion, lesser toes flexors and extensors, hallux flexors, and extensors was assessed in 20 people with diabetes and 20 healthy participants using hand-held dynamometry. The maximal isometric ankle plantarflexion and dorsiflexion were imported to OpenSim software to calculate 12 individual muscle (8 plantarflexors and 4 dorsiflexors) forces acting on ankle joint. RESULTS A significant reduction in ankle strength for all measured actions and a significant decrease in muscle force for each of the 12 muscles during dorsi and plantar flexion were observed. Furthermore, the ratios of agonist to antagonist muscle force for 6 of the muscles were significantly different between the control group and the group with diabetes. CONCLUSIONS It is likely that the muscles for which the agonist/antagonist muscle force ratio was significantly different for the healthy people and the people with diabetes could be more affected by diabetes

Cut-off Value of Random Blood Glucose among Asian Indians for Preliminary Screening of Persons with Prediabetes and Undetected Type 2 Diabetes Defined by the Glycosylated Haemoglobin Criteria.

AIM: The increased morbidity and mortality due to type 2 diabetes can be partly due to its delayed diagnosis. In developing countries, the cost and unavailability of conventional screening methods can be a setback. Use of random blood glucose (RBG) may be beneficial in testing large numbers at a low cost and in a short time in identifying persons at risk of developing diabetes. In this analysis, we aim to derive the values of RBG corresponding to the cut-off values of glycosylated hemoglobin (HbA1c) used to define prediabetes and diabetes. METHODS: Based on their risk profile of developing diabetes, a total of 2835 individuals were screened for a large diabetes prevention study. They were subjected to HbA1c testing to diagnose prediabetes and diabetes. Random capillary blood glucose was also performed. Correlation of RBG with HbA1c was computed using multiple linear regression equation. The optimal cut-off value for RBG corresponding to HbA1c value of 5.7% (39 mmol/mol), and ≥ 6.5% (48 mmol/mol) were computed using the receiver operating curve (ROC). Diagnostic accuracy was assessed from the area under the curve (AUC) and by using the Youden's index. RESULTS: RBG showed significant correlation with HbA1c (r=0.40, p<0.0001). Using the ROC analysis, a RBG cut-off value of 140.5 mg/dl (7.8 mmol/L) corresponding to an HbA1c value of 6.5% (48mmol/mol) was derived. A cut-off value could not be derived for HbA1c of 5.7% (39 mmol/mol) since the specificity and sensitivity for identifying prediabetes were low. CONCLUSION: Use of a capillary RBG value was found to be a simple procedure. The derived RBG cut-off value will aid in identifying people with undiagnosed diabetes. This preliminary screening will reduce the number to undergo more cumbersome and invasive diagnostic testing

The relationship between hallux grip force and balance in people with diabetes

Background: Diabetes accelerates the decline in muscle strength in older people and substantially increases the risk for fall and injury. Weakening of lower extremity muscles, in particular, is a strong predictor for falls, but currently there is no established method for its assessment in clinics. The paper grip test (PGT) offers a qualitative assessment of hallux plantar flexor strength and its usefulness for predicting falls has been demonstrated in non-diabetic populations. Research question: The aim of this study is to test whether the PGT can be used for a quantitative assessment of lower-extremity strength and to investigate its relationship with isometric muscle strength and balance in people with diabetes and peripheral neuropathy. Methods: Isometric muscle strength of all muscle groups of the foot-ankle was assessed using a dynamometer in sixty-nine people with diabetes and neuropathy. Postural sway and the gripping force exerted by the participants during the PGT was measured for the same participants using a plantar pressure assessment system. These measurements were repeated in regular intervals for 18 months in a longitudinal observational cohort study. Results: Cross-sectional analysis of baseline data showed that people who failed the PGT swayed more. Analysis of longitudinal data showed that increasing hallux grip force is significantly associated with reduced postural sway. No significant association was found between dynamometry-based measurements of strength and postural sway. Hallux grip force was significantly correlated to the strength of all muscle groups of the foot-ankle complex. Significance: These results indicate that hallux grip force can assess the strength of the foot-ankle muscles and could potentially be used to identify people at risk of falling. This sets the basis for the development of new screening protocols to assess weakening of the muscles of the foot-ankle and to enhance risk assessment for falls in people with diabetes and peripheral neuropathy

Association of ACE Polymorphism and Diabetic Nephropathy in South Indian Patients

Objective: To study the association of ACE gene polymorphism and diabetic nephropathy in South Indian subjects. Setting: Outpatient clinic of a specialized hospital. Patients: The study included 109 South Indian type 2 diabetic patients (72 males and 37 females; age 56.7±9.0 years, mean±SD). The patients were subdivided into two groups: nephropathic (n=86) and normoalbuminuric patients (n=23). Interventions: Genomic DNA was isolated from the peripheral blood leukocytes. To determine the ACE genotype, genomic DNA was amplified by PCR initially using a flanking primer pair and, subsequently when necessary, with a primer pair that recognizes the insertion specific sequence for confirmation of the specificity of the amplification reactions. Main outcome measures: ACE genotype distribution in the two study groups. Results: In the nephropathic patients, ID and DD genotypes were present in 52.3% and 27.9% of the patients, respectively as compared to 34.8% and 21.7% respectively in those with normoalbuminuria. The D allele was present in 80.2% of the nephropathic patients and 56.5% of the normoalbuminuric patients (c 2=4.28, P=0.039; odds ratio 3.12). Therefore, the higher percentage of II genotype in the normoalbuminuric group was 43.5% as compared to the 19.8% in nephropathic patients. Conclusions: This study showed a positive association between the D allele (ID and DD genotype) of the ACE polymorphism and diabetic proteinuria in South Indian type 2 diabetic patients. Our findings are in keeping with several earlier studies showing a strong association of the D allele of the ACE gene with diabetic nephropathy

Impact of diabetes education and self-management on the quality of care for people with type 1 diabetes mellitus in the Middle East (the International Diabetes Mellitus Practices Study, IDMPS)

Aims: Self-management (self-monitoring of blood glucose, plus self-adjustment of insulin dose) is important in diabetes care, but its complexity presents a barrier to wider implementation, which hinders attainment and maintenance of glycemic targets. More evidence on self-management is needed to increase its implementation and improve metabolic outcomes. Methods: Data from 1316 participants with type 1 diabetes mellitus who were enrolled from Middle East countries into the International Diabetes Management Practices Study (IDMPS), a multinational observational survey, were analyzed to assess the impact of education on disease management and outcomes. Results: A majority (78%) of participants failed to achieve glycemic target (HbA1c < 7.0% [<53 mmol/mol]). Participants who had received diabetes education (59%) were more likely to practice self-management than those who had not (odds ratio [OR]: 2.51; 95% confidence interval [CI]: 1.7–3.69; p < 0.001), and those who practiced self-management were more likely to attain target HbA1c than those who did not (OR: 1.49; 95% CI: 1.06–2.09; p = 0.023).Fil: Gagliardino, Juan Jose.

Diabetes education and health insurance: How they affect the quality of care provided to peoplewith type 1 diabetes in Latin America. Data from the International Diabetes Mellitus Practices Study (IDMPS)

Aims: This study aimed to evaluate the impact of diabetes education and access to healthcare coverage on disease management and outcomes in Latin America. Methods: Data were obtained from a sub-analysis of 2693 patients with type 1 diabetes mellitus recruited from 9 Latin American countries as part of the International Diabetes Mellitus Practices Study (IDMPS), a multinational, observational survey of diabetes treatment in developing regions. Results: Results from the Latin American cohort show that only 25% of participants met HbA1c target value (< 7% [53 mmol/mol]). Attainment of this target was significantly higher among participants who had received diabetes education than those who hadn´t (28% vs. 19%, p < 0.001), and among those who practiced self-management (27% vs. 21% no self-management, p = 0.001). Multivariate analysis showed that participants who had received diabetes education were more likely to manage their diabetes (OR: 1.65 [95% CI: 1.24, 2.19]; p = 0.001), and to attain HbA1c target values (OR: 1.48 [95% CI: 1.14, 1.93]; p = 0.003). Conclusions: Given the association between uncontrolled diabetes and long-term complications, health authorities and care providers should increase efforts to ensure widespread healthcare coverage and access to self-management education to reduce the socioeconomic and humanistic burden of type 1 diabetes.Fil: Gagliardino, Juan Jose.
