Association between Dietary Habits and Type 2 Diabetes Mellitus in Yangon, Myanmar: A Case-Control Study.

In Myanmar, the escalating prevalence of type 2 diabetes mellitus (T2DM) and impaired glucose tolerance among adults was recently reported, with the highest prevalence in the Yangon Region. The aim of the present study was to identify the risk factors in dietary habits and their relationship with T2DM in urban Myanmar residents. We conducted a case-control study recruiting 300 individuals aged 25-74 years living in the Yangon Region, consisting of 150 newly diagnosed cases attending a diabetes clinic, and 150 controls, who were community residents and free of diabetes. The case group had a significantly higher consumption of noodles, fish, beans, fermented food and pickles, dried food, topping seasonings, and non-dairy milk products than the control group, whereas they had a lower vegetable intake (more than three servings/day) and fruit intake (more than three servings/day) than the control group. Furthermore, the case group exhibited a higher frequency of some dietary behaviors than the control group, such as (1) having meals with family, (2) skipping breakfast, and (3) eating out. The final model showed that topping seasonings (adjusted odds ratio (aOR) 11.23, 95% confidence interval (CI) 3.08-40.90), more than three servings/day of vegetable intake (aOR 0.18, 95% CI 0.05-0.67), and having meals with family (aOR 2.23, 95% CI 1.05-4.71) were associated with diabetes. The study suggests that Myanmar's characteristic dietary culture of topping their meals with salty seasonings and sauces and eating multiple dishes together as a family are risk factors associated with T2DM. Our findings may contribute recommendations and opportunities for the primary prevention of T2DM in urban Myanmar.

Social Support between Diabetes Patients and Non-Diabetes Persons in Yangon, Myanmar: A Study Applying ENRICHD Social Support Instrument.

Diabetes patients, due to the chorionic nature of the disease, need complex and long-term care for control and prevention of complications. The patients themselves find it difficult to adopt appropriate disease management after diagnosis and they need social support from family, friends, and their environment, especially in lower- and middle-income countries where medical service is limited, and they need self-care of disease and lifestyle modification. In Myanmar, however, the study for social support among diabetes patients is still limited. Therefore, we conducted a case-control study to investigate the social support among diabetes patients and the association between socioeconomic factors in Yangon, which has the highest prevalence of diabetes in Myanmar. Social support between diabetes patients who came to diabetes special clinics and non-diabetes community control was assessed by applying transculturally translated ENRICHD Social Support Instrument (ESSI). Among the diabetes patients' group, more than 70% had high perceived social support, specifically higher level of informational and emotional social support. Robust multiple regression models revealed significant positive associations between total social support and independent variables: p value < 0.001 for monthly household income and being married, and p value < 0.05 for household number and frequency of having meals together with family. These findings suggest that perceived social support among patients with diabetes may be mainly affected by the patients' family conditions, such as household income and living with a spouse, in Myanmar culture.

Physical Activity of Type 2 Diabetes Mellitus Patients and Non-Diabetes Participants in Yangon, Myanmar: A Case-Control Study Applying the International Physical Activity Questionnaires (IPAQ-S).

BACKGROUND: Despite the evidence that physical activity (PA) can prevent type 2 diabetes mellitus (T2DM), limited research investigated the level of PA among diabetes and non-diabetes in Myanmar, where there is the escalating prevalence of diabetes recently. We investigated PA as modified the risk of diabetes, in a case-control study. METHODS: We conducted a case-control study which included 150 cases and 150 controls age 25-74 years (Mean age 43.3±14.7 years) among the cases and (55.1±10.9 years) among the controls, both sex and residence in Yangon. Cases were newly diagnosed with T2DM within six months before data collection, with laboratory-confirmed fasting blood glucose level ≥126mg/dl. Controls were community residents, without diabetes, confirmed with a laboratory test. The IPAQ-S was used to assess the PA level. Multiple logistic regression analysis was applied in STATA 15, using the interaction terms for age and PA, adjusting age, sex and BMI. RESULTS: In comparison to controls, cases were older and having less PA knowledge. The levels of vigorous PA were mean 254.9±standard deviations (SD) 845.6 METsmin.wk-1 among controls, 73.06±392.1 cases, moderate PA 631.5±1240.8 METsmin.wk-1 among controls and 1050.9±1601.6 cases and walking PA 569.8±1060 METsmin.wk-1 among controls and 777.4±1249 cases, respectively. The multiple logistic regression analysis showed adjusted odds ratios (aOR) 3.84, 95% confidence interval (CI) 1.18-12.42 (P<0.05) for those aged 40 and older, with moderate PA and aOR 18.01, Cl 6.45-50.26 (P<0.001) for those aged 40 and older, with low PA. Comparing the strength of association, the risk of T2DM among people aged 40 and older with moderate PA is lower than age over 40 with low PA. CONCLUSION: PA lessened the risk of T2DM, posted by increasing age. The findings highlighted the importance of promoting PA to reduce the T2DM prevalence in the context of Yangon, Myanmar, a low- and middle-income Asian country.

BE-SMART (Basal Early Strategies to Maximize HbA1c Reduction with Oral Therapy): Expert Opinion.

The past three decades have seen a quadruple rise in the number of people affected by diabetes mellitus worldwide, with the disease being the ninth major cause of mortality. Type 2 diabetes mellitus (T2DM) often remains undiagnosed for several years due to its asymptomatic nature during the initial stages. In India, 70% of diagnosed diabetes cases remain uncontrolled. Current guidelines endorse the initiation of insulin early in the course of the disease, specifically in patients with HbA1c > 10%, as the use of oral agents alone is unlikely to achieve glycemic targets. Early insulin initiation and optimization of glycemic control using insulin titration algorithms and patient empowerment can facilitate the effective management of uncontrolled diabetes. Early glucose control has sustained benefits in people with diabetes. However, insulin initiation, dose adjustment, and the need to repeatedly assess blood glucose levels are often perplexing for both physicians and patients, and there are misconceptions and concerns regarding its use. Hence, an early transition to insulin and ideal intensification of treatment may aid in delaying the onset of diabetes complications. This opinion statement was formulated by an expert panel on the basis of existing guidelines, clinical experience, and economic and cultural contexts. The statement stresses the timely and appropriate use of basal insulin in T2DM. It focuses on the seven vital Ts-treatment initiation, timing of administration, transportation and storage, technique of administration, targets for titration, tablets, and tools for monitoring.Funding: Sanofi.

Measurement of diabetes, prediabetes and their associated risk factors in Myanmar 2014.

BACKGROUND: Myanmar, a low-income Southeast Asia country with an estimated population of 53.9 million, is currently facing an increasing burden of noncommunicable diseases. Research that systematically measures and reports the national prevalence of diabetes and prediabetes within Myanmar represents a gap in the literature. This study, a national survey, was conducted with the objectives of 1) measuring diabetic population, 2) measuring the prediabetic population, and 3) finding out the risk factors leading to diabetes and prediabetes in Myanmar. METHOD: Multistage sampling was applied in proportional cluster approach to recruit a nationally representative sample of 8,575 participants from 52 townships selected to represent 332 townships across the country. The Ethical Committee of the Department of Medical Research (Lower Myanmar) approved the current study. Fasting plasma glucose and the level of glucose 2 hours after 75 g glucose load were applied, to screen for diabetes and prediabetes. Interviewer-administered questionnaires were carried out to investigate demographic and lifestyle behaviors. Stadiometer, weighing scale, measuring tape, and Omron blood pressure monitor measuring devices were used for the anthropometric measurements. Survey data analysis used STATA version 13 and application of descriptive statistics with multinomial logistic regression. RESULT: Prevalence of diabetes in Myanmar was 10.8%: 11.5% in males and 9.2% in females. Overall prevalence of prediabetes was 19.7%: 16.5% in males and 23% in females. Increasing age, urban residence, big waist circumference, and high triglyceride level were significant factors associated with diabetes and prediabetes. Many people with diabetes were found to lack knowledge and awareness of diabetes. CONCLUSION: Diabetes prevalence in Myanmar is high, and relatively higher than that reported in many Association of Southeast Asian Nations countries. The study findings call for urgent nationwide public health action in Myanmar such as screening people at risk of diabetes and prevention of the disease. The findings can also assist the health authority in Myanmar with the preparation and allocation of resources for diabetes prevention.

Expert Opinion: Patient Selection for Premixed Insulin Formulations in Diabetes Care.

Premixed insulins are an important tool for glycemic control in persons with diabetes. Equally important in diabetes care is the selection of the most appropriate insulin regimen for a particular individual at a specific time. Currently, the choice of insulin regimens for initiation or intensification of therapy is a subjective decision. In this article, we share insights, which will help in rational and objective selection of premixed formulations for initiation and intensification of insulin therapy. The glycemic status and its variations in a person help to identify the most appropriate insulin regimen and formulation for him or her. The evolution of objective glucometric indices has enabled better glycemic monitoring of individuals with diabetes. Management of diabetes has evolved from a 'glucocentric' approach to a 'patient-centered' approach; patient characteristics, needs, and preferences should be evaluated when considering premixed insulin for treatment of diabetes.Funding: Novo Nordisk, India.

Consensus Recommendations on Sulfonylurea and Sulfonylurea Combinations in the Management of Type 2 Diabetes Mellitus - International Task Force.

For decades, sulfonylureas (SUs) have been important drugs in the antidiabetic therapeutic armamentarium. They have been used as monotherapy as well as combination therapy. Focus on newer drugs and concerns about the risk of severe hypoglycemia and weight gain with some SUs have led to discussion on their safety and utility. It has to be borne in mind that the adverse events associated with SUs should not be ascribed to the whole class, as many modern SUs, such as glimepiride and gliclazide modified release, are associated with better safety profiles. Furthermore, individualization of treatment, using SUs in combination with other drugs, backed with careful monitoring and patient education, ensures maximum benefits with minimal side effects. The current guidelines, developed by experts from Africa, Asia, and the Middle East, promote the safe and smart use of SUs in combination with other glucose-lowering drugs.

Choice of Insulin in Type 2 Diabetes: A Southeast Asian Perspective.

Southeast Asia faces a diabetes epidemic, which has created significant challenges for health care. The unique Asian diabetes phenotype, coupled with peculiar lifestyle, diet, and healthcare-seeking behavior, makes it imperative to develop clinical pathways and guidelines which address local needs and requirements. From an insulin-centric viewpoint, the preparations prescribed in such pathways should be effective, safe, well tolerated, nonintrusive, and suitable for the use in multiple clinical situations including initiation and intensification. This brief communication describes the utility of premixed or dual action insulin in such clinical pathways and guidelines.

Malaria epidemiology in central Myanmar: identification of a multi-species asymptomatic reservoir of infection.

BACKGROUND: The spread of artemisinin-resistant Plasmodium falciparum is a global health concern. Myanmar stands at the frontier of artemisinin-resistant P. falciparum. Myanmar also has the highest reported malaria burden in Southeast Asia; it is integral in the World Health Organization's plan to eliminate malaria in Southeast Asia, yet few epidemiological data exist for the general population in Myanmar. METHODS: This cross-sectional, probability household survey was conducted in Phyu township, Bago Region (central Myanmar), during the wet season of 2013. Interviewers collected clinical and behavioural data, recorded tympanic temperature and obtained dried blood spots for malaria PCR and serology. Plasmodium falciparum positive samples were tested for genetic mutations in the K13 region that may confer artemisinin resistance. Estimated type-specific malaria PCR prevalence and seroprevalence were calculated, with regression analysis to identify risk factors for seropositivity to P. falciparum. Data were weighted to account for unequal selection probabilities. RESULTS: 1638 participants were sampled (500 households). Weighted PCR prevalence was low (n = 41, 2.5%) and most cases were afebrile (93%). Plasmodium falciparum was the most common species (n = 19. 1.1%) and five (26%) P. falciparum samples harboured K13 mutations. Plasmodium knowlesi was detected in 1.0% (n = 16) and Plasmodium vivax was detected in 0.4% (n = 7). Seroprevalence was 9.4% for P. falciparum and 3.1% for P. vivax. Seroconversion to P. falciparum was 0.003/year in the whole population, but 16-fold higher in men over 23 years old (LR test p = 0.016). DISCUSSION: This is the first population-based seroprevalence study from central Myanmar. Low overall prevalence was discovered. However, these data suggest endemic transmission continues, probably associated with behavioural risk factors amongst working-age men. Genetic mutations associated with P. falciparum artemisinin resistance, the presence of P. knowlesi and discrete demographic risk groups present opportunities and challenges for malaria control. Responses targeted to working-age men, capable of detecting sub-clinical infections, and considering all species will facilitate malaria elimination in this setting.

Prevalence and determinants of hypertension in Myanmar - a nationwide cross-sectional study.

BACKGROUND: Non-communicable diseases (NCDs), malaria and tuberculosis dominate the disease pattern in Myanmar. Due to urbanization, westernized lifestyle and economic development, it is likely that NCDs such as cerebrovascular disease and ischemic heart disease are on a rise. The leading behavioral- and metabolic NCDs risk factors are tobacco smoke, dietary risks and alcohol use, and high blood pressure and body mass index, respectively. The study aimed at estimating the prevalence and determinants of hypertension, including metabolic-, behavioral- and socio-demographic risk factors. METHODS: A nationwide, cross-sectional study of 7429 citizens of Myanmar aged 15-64 years were examined in 2009, using the WHO STEPS methodology. In separate analyses by gender, odds radios (ORs) and 95 % confidence intervals (CIs) for determinants of hypertension were estimated using logistic regression analyses. Confounders included in analyses were chosen based on Directed acyclic graphs (DAGs). RESULTS: The prevalence of hypertension was 30.1 % (95 % CI: 28.4-31.8) in males and 29.8 % (28.5-31.1) in females. The mean BMI was 21.7 (SD 4.3) kg/m(2) for males and 23.0 (5.1) kg/m(2) for females. In fully adjusted analyses, we found in both genders increased OR for hypertension if the participants had high BMI (males: OR = 2.6; 95 % CI 2.1-3.3, females: OR = 2.3; 2.0-2.7) and high waist circumference (males: OR = 3.4; 1.8-6.8, females: OR = 2.7; 2.2-3.3). In both sexes, associations were also found between hypertension and low physical activity at work, or living in urban areas or the delta region. Being underweight and use of sesame oil in cooking was associated with lower odds for hypertension. CONCLUSIONS: The prevalence of hypertension was high and associated with metabolic-, behavioral- and socio-demographic factors. Due to expected rapid economic growth in Myanmar we recommend similar studies in the future to follow up and describe trends in the risk factors, especially modifiable factors, which will most likely be on rise. Studies on effectiveness on interventions are needed, and policies to reduce the burden of NCD risk factors should be implemented if proven effective in similar settings.

Gaps and challenges to integrating diabetes care in Myanmar.

In common with other low-income countries, diabetes is a growing challenge for Myanmar. Gaps and challenges exist in political commitment, policy development, the health system, treatment-seeking behaviour and the role of traditional medicine. National policies aimed at prevention - such as to promote healthy food, create a healthy environment conducive to increased physical activity, restrict marketing of unhealthy food, and initiate mass awareness-raising programmes - need to be strengthened. Moreover, existing initiatives for prevention of noncommunicable-disease (NCD) are channelled vertically rather than being horizontally integrated. Primary health care is traditionally orientated more towards prevention of infectious diseases and staff often lack training in prevention and control of NCDs. Capacity-building activities have been modest to date, and retaining trained health workers in diabetes-oriented activities is a challenge. The World Health Organization Package of Essential Noncommunicable (PEN) disease interventions for primary health care in low-resource settings has been piloted in Yangon Region and country-wide expansion awaits ministerial approval. Recently, the Myanmar Diabetes Care Model was proposed by the Myanmar Diabetes Association, with the aims of both bridging the gap in diabetes care between rural and urban areas and strengthening care at the secondary and tertiary levels. However, implementation will require policy development for essential drugs and equipment, capacity-strengthening of health-care workers, and an appropriate referral and health-information system.

Challenges in Type 1 diabetes management in South East Asia: Descriptive situational assessment.

Treatment of type 1 diabetes is a challenging issue in South East Asia. Unlike in the developed countries, patients have to procure insulin, glucometer strips and other treatment facilities from their own pockets. Coupled with poor resources are the difficulties with diagnosis, insulin initiation, insulin storage, marital and emotional challenges. Being a disease affecting only a minority of people, it is largely ignored by the governments and policy makers. Comprehensive diagnostic, treatment and team based educational facilities are available only in the speciality diabetes centers in the private sector whereas majority of the subjects with type 1 diabetes are from a poor socio-economic background. Unlike in the Western world, being known as a diabetes patient is a social sigma and poses huge emotional burden living with the disease and getting married. Even with best of the resources, long-term treatment of type 1 diabetes still remains a huge challenge across the globe. In this review, authors from India, Pakistan, Nepal, Sri Lanka, Myanmar and Bangladesh detail the country-specific challenges and discuss the possible solutions.

South Asian Consensus Guidelines for the rational management of diabetes in human immunodeficiency virus/acquired immunodeficiency syndrome.

As newer methods of management are made available, and accessible, survival rates with human immunodeficiency virus (HIV) are increasing. This means that chronic, metabolic complications of HIV are becoming more frequent in clinical practice, as acute morbidity is controlled. Management of HIV/acquired immunodeficiency syndrome (AIDS) is gradually expanding to include these chronic and metabolic complications of the disease, and the adverse effects associated with its treatments, including diabetes. Unfortunately, no guidelines are available to help the medical practitioners choose appropriate therapy for patients with these conditions. The aim of the South Asian Consensus Guidelines is to provide evidence-based recommendations to assist healthcare providers in the rational management of type 2 diabetes mellitus in patients with HIV. The development of these guidelines used systematic reviews of available evidence to form its key recommendations. These guidelines and associated review of literature represent a compilation of available knowledge regarding rational management of diabetes in HIV. Patients of diabetes with concomitant HIV infection are managed optimally with insulin therapy and judicious use of highly active antiretroviral therapy with suitable alternatives is also recommended. These guidelines should prove helpful to physicians, not only in South Asia, but also across the globe, while managing patients with coexistent HIV and diabetes.

Management of hyperglycemia in geriatric patients with diabetes mellitus: South Asian consensus guidelines.

Asia is home to four of the world's five largest diabetic populations, two of them being South Asian nations, namely, India and Pakistan. This problem is compounded by a substantial rise in the elderly population in Asian countries. On the other hand, the heterogeneous health condition and multiple co-morbidities make the care of chronic disease in the elderly a challenging task. The aim of the South Asian Consensus Guidelines is to provide evidence-based recommendations to assist healthcare providers in the rational management of type 2 diabetes mellitus in the elderly population. Current Guidelines used systematic reviews of available evidence to form its key recommendations. No evidence grading was done for the purpose of this manuscript. The clinical questions of the guidelines, the methodology of literature search, and medical writing strategy were finalized by consultations in person and through mail. The South Asian Consensus guideline emphasizes tailoring of glycemic goals for patients based on age, co-morbid conditions especially that of cardiovascular system, risk of hypoglycemia, and life expectancy. It also recommends cautious use of available pharmacotherapy in geriatric patients with diabetes. The primary principle of diabetes therapy should be to achieve euglycemia, without causing hypoglycemia. Appropriate use of modern insulins and oral drugs, including incretin mimetics will help physicians achieve this aim.
