Transcultural diabetes nutrition therapy algorithm: the Asian Indian application

The Transcultural Diabetes Nutrition Algorithm: A Middle Eastern Version

Diabetes prevalence is on the rise in the Middle East. In countries of the Gulf region-Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates-prevalence rates are among the highest in the world. Further, Egypt now ranks as one of the top 10 countries in the world for high number of people with diabetes. Medical nutrition therapy is key to optimal management of diabetes. Patient adherence to nutritional guidance depends on advice that is tailored to regional foods and cultural practices. In 2012, international experts created a transcultural Diabetes Nutrition Algorithm (tDNA) for broad applicability. The objective of this current project was to adapt the algorithm and supportive materials to the Middle East region. A Task Force of regional and global experts in the fields of diabetes, obesity, and metabolic disorders met to achieve consensus on Middle East-specific adaptations to the tDNA. Recommendations, position statements, figures, and tables are presented here, representing conclusions of the tDNA-Middle Eastern (tDNA-ME) Task Force. Educational materials can be used to help healthcare professionals optimize nutritional care for patients with type 2 diabetes. The tDNA-ME version provides evidence-based guidance on how to meet patients' nutritional needs while following customs of people living in the Middle Eastern region.

Transcultural Lifestyle Medicine in Type 2 Diabetes Care: Narrative Review of the Literature

Disparities in type 2 diabetes (T2D) care is a global problem across diverse cultures. The Dysglycemia-Based Chronic Disease (DBCD) model promotes early and sustainable interventions along the insulin resistance (stage 1), prediabetes (stage 2), T2D (stage 3), and complications (stage 4) spectrum. In this model, lifestyle medicine is the cornerstone of preventive care to reduce DBCD progression and the socioeconomic/biological burden of disease. A comprehensive literature review, spanning 2000 to 2021, was performed and 55 studies were included examining the effects of lifestyle medicine and their cultural adaptions with different prevention modalities. In stage 1, primordial prevention targets modifiable primary drivers (behavior and environment), unhealthy lifestyles, abnormal adiposity, and insulin resistance with educational and motivational health promotion activities at individual, group, community, and population-based scales. Primary, secondary, and tertiary prevention targets individuals with mild hyperglycemia, severe hyperglycemia, and complications, respectively, using programs that incorporate structured lifestyle interventions. Culturally adapted lifestyle change in primary and secondary prevention improved quality of life and biomarkers, but with a limited impact of tertiary prevention on cardiovascular events. In conclusion, lifestyle medicine with cultural adaptations is an integral part of preventive care in patients with T2D. However, considerable research gaps exist, especially for tertiary prevention.

Roles for community health workers in diabetes prevention and management in low- and middle-income countries

Diabetes prevalence is increasing worldwide, especially in low- and middle-income countries (LMIC), posing the need for improved detection and management strategies. Chronic disease models and lifestyle medicine provide structures for action. Community health workers (CHWs) can significantly contribute to chronic disease care if they are trained and integrated into low-resource health systems. Although most current CHWs worldwide are performing maternal/child health and infectious disease-related tasks, other programs involving CHWs for noncommunicable disease prevention and management are increasing. In this article, we discuss the advantages, challenges, and questions regarding possible roles assigned to CHWs in the prevention and management of diabetes. These roles include performing simple screening tests, implementing lifestyle/behavioral interventions, and connecting patients with alternatives to biomedicine. Specifically, CHWs can aid diabetes epidemiological surveillance by conducting risk score-based screening or capillary glucose testing, and they can facilitate diabetes self-management by delivering interventions described in the transcultural diabetes nutrition algorithm. Furthermore, while this role has not formally been assigned, CHWs can leverage their intimate knowledge of local practices to provide decision-making support to patients in environments with pluralistic health systems. Ethnocultural differences in CHW functions and transcultural adaptations of their roles in diabetes care should also be considered. In summary, CHWs can improve diabetes care by screening high-risk individuals and implementing lifestyle interventions, especially in LMIC.

Measured sodium excretion is associated with CKD progression: results from the KNOW-CKD study

BACKGROUND

Diet is a modifiable factor of chronic kidney disease (CKD) progression. However, the effect of dietary salt intake on CKD progression remains unclear. Therefore, we analyzed the effect of dietary salt intake on renal outcome in Korean patients with CKD.

METHODS

We measured 24-h urinary sodium (Na) excretion as a marker of dietary salt intake in the prospective, multi-center, longitudinal KoreaN cohort study for Outcome in patients With CKD (KNOW-CKD). Data were analyzed from CKD patients at Stages G3a to G5 (n = 1254). We investigated the association between dietary salt intake and CKD progression. Patients were divided into four quartiles of dietary salt intake, which was assessed using measured 24-h urinary Na excretion. The study endpoint was composite renal outcome, which was defined as either halving the estimated glomerular filtration rate or developing end-stage renal disease.

RESULTS

During a median (interquartile range) follow-up of 4.3 (2.8-5.8) years, 480 (38.7%) patients developed the composite renal event. Compared with the reference group (Q2, urinary Na excretion: 104.2 ≤ Na excretion < 145.1 mEq/day), the highest quartile of measured 24-h urinary Na excretion was associated with risk of composite renal outcome [Q4, urinary Na excretion ≥192.9 mEq/day, hazard ratio 1.8 (95% confidence interval 1.12-2.88); P = 0.015] in a multivariable hazards model. Subgroup analyses showed that high-salt intake was particularly associated with a higher risk of composite renal outcome in women, in patients <60 years of age, in those with uncontrolled hypertension and in those with obesity.

CONCLUSIONS

High salt intake was associated with increased risk of progression in CKD.

Glycemic improvement with a novel interim intervention technique using retrospective professional continuous glucose monitoring (GLITTER study): A study from Mumbai, India

BACKGROUND/AIMS

To assess the efficacy of a novel interim intervention technique using retrospective, blinded, professional continuous glucose monitoring system (pro CGM) with the Freestyle Libre Pro system over a 14-day single sensor wear-period.

METHODS

A retrospective analysis comprised of 105 consecutive adults at single centre in India with Type 2 diabetes, HbA1c > 53 mmol/mol (>7%), on non-insulin divabetes agents and/or insulin. The interim intervention technique included three visits over 14 days: Visit 1, sensor placed and patients asked to keep a food log while on pro-CGM; Visit 2 (within 1 week), interim assessment of pro CGM and diet or pharmacotherapy modifications made accordingly; Visit 3 at day 14, pro CGM re-evaluated to assess glycemic control. Glucose target range was set at 70-180 mg/dL. Analyses included pre & post daily average glucose, time in range, time above range, and time below range.

RESULTS

Average time for interim analysis was 5 days after pro CGM initiation. At Visit 3, daily average glucose decreased from 191.3 mg/dL at baseline to 137.4 mg/dL (p < 0.001). Time in range improved from 42.2% to 80.2% (p < 0.001). Time above range decreased from 52.1% to 18.3% (p < 0.001), with a concurrent decrease in time below range from 5.7% to 1.5% (p < 0.001). Recurrent hypoglycemia was detected in 27 (25.7%) individuals, whose average baseline time below range reduced from 21.1% to 1.9% (p < 0.001).

CONCLUSION

The interim intervention technique is a cost effective and efficient method for improving glucose outcomes through lifestyle and pharmacotherapy modifications and while utilizing a single pro-CGM sensor.

Synthesis: Deriving a Core Set of Recommendations to Optimize Diabetes Care on a Global Scale

BACKGROUND

Diabetes afflicts 382 million people worldwide, with increasing prevalence rates and adverse effects on health, well-being, and society in general. There are many drivers for the complex presentation of diabetes, including environmental and genetic/epigenetic factors.

OBJECTIVE

The aim was to synthesize a core set of recommendations from information from 14 countries that can be used to optimize diabetes care on a global scale.

METHODS

Information from 14 papers in this special issue of Annals of Global Health was reviewed, analyzed, and sorted to synthesize recommendations. PubMed was searched for relevant studies on diabetes and global health.

FINDINGS

Key findings are as follows: (1) Population-based transitions distinguish region-specific diabetes care; (2) biological drivers for diabetes differ among various populations and need to be clarified scientifically; (3) principal resource availability determines quality-of-care metrics; and (4) governmental involvement, independent of economic barriers, improves the contextualization of diabetes care. Core recommendations are as follows: (1) Each nation should assess region-specific epidemiology, the scientific evidence base, and population-based transitions to establish risk-stratified guidelines for diagnosis and therapeutic interventions; (2) each nation should establish a public health imperative to provide tools and funding to successfully implement these guidelines; and (3) each nation should commit to education and research to optimize recommendations for a durable effect.

CONCLUSIONS

Systematic acquisition of information about diabetes care can be analyzed, extrapolated, and then used to provide a core set of actionable recommendations that may be further studied and implemented to improve diabetes care on a global scale.

Adipocytokines and anthropometric measures in type 2 diabetics

AIM

Type 2 diabetes mellitus has assumed pandemic proportions worldwide. Aggressive management of hyperglycemia in diabetics is a primary goal of treatment. We have previously reported favorable effects of oral hypoglycemic agents on adipocytokines. Aim of the present study was to investigate the relationship of adipocytokines with anthropometric measures and biochemical parameters in type 2 diabetics.

METHODS

Clinically diagnosed type 2 diabetics and age, gender matched healthy volunteers were recruited for study. Anthropometric measurements like height, weight, waist-circumference, hip-circumference were recorded and BMI, waist-hip ratio were calculated. Fasting blood samples were collected from participants and sera were analyzed for glucose, glycated haemoglobin, total cholesterol, SGOT, SGPT, insulin, adiponectin and leptin. Correlation of adipocytokines with anthropometric and biochemical parameters was assessed in healthy and diabetic individuals.

RESULTS

BMI and WHR in diabetics were significantly higher than healthy population. BMI did not show significant association with adipocytokines. Diabetic males with WHR≥0.9 showed negative association with adiponectin and positive association with leptin. WC did not show significant association with adipocytokines in males. Irrespective of WC, healthy females exhibited positive association with leptin. Diabetic females with WC≥88cm showed leptin to be positively associated with WC. Such association of adipocytokines with WHR was not detected in females.

CONCLUSIONS

Body fat distribution can be considered as a parameter in assessing adipokine imbalance. Central adiposity is a better measure of adipokine imbalance than BMI. Abdominal obesity in diabetics correlates with altered levels of adipocytokines indicating its importance in diabetic individuals.

Influence of Socioeconomic Status on Knowledge of Obesity and Diabetes among Adolescents in Chennai, South India

The Obesity Reduction and Awareness of Non-communicable disease through Group Education (ORANGE) Phase II program, is a school-based intervention aimed at healthy lifestyle practices for sixth and seventh grade adolescents (n = 2345) attending private (n = 1811) and government (n = 534) schools in Chennai. The objectives of this paper are (a) to describe the intervention activities and their outcomes qualitatively and (b) to report changes in body mass index (BMI) of the intervention group participants. This intervention strategy used a teacher-peer-training model in each school for long-term sustainability of the lessons learned from this program. During each intervention session, teachers led a classroom discussion on the health topic of interest, and peers facilitated small-group learning activities. Anthropometric measurements of participants were assessed pre- and post-intervention. We found government school students perceived hygienic actions (e.g., drinking clean water, taking baths daily) as healthy habits for preventing diabetes, whereas private school students associated an expensive lifestyle (e.g., eating at restaurants, riding a car) with diabetes prevention. Overall, the mean post-intervention BMI (18.3 kg/m²) was in the normal range compared to the pre-intervention BMI (17.7 kg/m²) (p < 0.0001). These results suggest that future interventions should be tailored for adolescents from different socio-economic groups while acknowledging their varied perceptions.

Transcultural Endocrinology: Adapting Type-2 Diabetes Guidelines on a Global Scale

Type-2 diabetes (T2D) needs to be prevented and treated effectively to reduce its burden and consequences. White papers, such as evidence-based clinical practice guidelines (CPG) and their more portable versions, clinical practice algorithms and clinical checklists, may improve clinical decision-making and diabetes outcomes. However, CPG are underused and poorly validated. Protocols that translate and implement these CPG are needed. This review presents the global dimension of T2D, details the importance of white papers in the transculturalization process, compares relevant international CPG, analyzes cultural variables, and summarizes translation strategies that can improve care. Specific protocols and algorithmic tools are provided.

Patient-led versus physician-led titration of insulin glargine in patients with uncontrolled type 2 diabetes: a randomized multinational ATLAS study

OBJECTIVE

Self-adjustment of insulin dose is commonly practiced in Western patients with type 2 diabetes but is usually not performed in Asian patients. This multinational, 24-week, randomized study compared patient-led with physician-led titration of once-daily insulin glargine in Asian patients with uncontrolled type 2 diabetes who were on 2 oral glucose-lowering agents.

METHODS

Patient-led (n = 275) or physician-led (n = 277) subjects followed the same dose-titration algorithm guided by self-monitored fasting blood glucose (FBG; target, 110 mg/dL [6.1 mmol/L]). The primary endpoint was change in mean glycated hemoglobin (HbA1c) at week 24 in the patient-led versus physician-led titration groups.

RESULTS

Patient-led titration resulted in a significantly higher drop in HbA1c value at 24 weeks when compared with physician-led titration (-1.40% vs. -1.25%; mean difference, -0.15; 95% confidence interval, -0.29 to 0.00; P = .043). Mean decrease in FBG was greatest in the patient-led group (-2.85 mmol/L vs. -2.48 mmol/L; P = .001). The improvements in HbA1c and FBG were consistent across countries, with similar improvements in treatment satisfaction in both groups. Mean daily insulin dose was higher in the patient-led group (28.9 units vs. 22.2 units; P<.001). Target HbA1c of <7.0% without severe hypoglycemia was achieved in 40.0% and 32.9% in the patient-led and physician-led groups, respectively (P = .086). Severe hypoglycemia was not different in the 2 groups (0.7%), with an increase in nocturnal and symptomatic hypoglycemia in the patient-led arm.

CONCLUSION

Patient-led insulin glargine titration achieved near-target blood glucose levels in Asian patients with uncontrolled type 2 diabetes who were on 2 oral glucose-lowering drugs, demonstrating that Asian patients can self-uptitrate insulin dose effectively when guided.

Therapeutic potential of α-glucosidase inhibitors in type 2 diabetes mellitus: an evidence-based review

INTRODUCTION

Postprandial hyperglycemia (PPHG) contributes to micro- and macro-vascular complications more than fasting hyperglycemia in patients with type 2 diabetes mellitus. Due to the traditional carbohydrate-rich diet, Asians, particularly Indians and Chinese need agents to control the higher risk of uncontrolled PPHG. Targeting PPHG with α-glucosidase inhibitors (AGIs), either alone or in combination with other oral hypoglycemic agents and insulin, provide overall glycemic control with transient mild gastrointestinal disorders. Treatment with AGIs, especially acarbose, has also shown to provide beneficial effects on lipid levels, blood pressure, coagulation factors, carotid intima-media thickness and endothelial dysfunction. New insights of acarbose therapy obtained like increased activity of gut hormones and improved gut microbiota may explain the benefits on weight, whereas increased production of H2 may explains its cardiovascular benefits to some extent.

AREAS COVERED

A systematic search strategy was developed to identify randomized controlled trials in MEDLINE, PubMed, EMBASE and ongoing trials databases.

EXPERT OPINION

AGIs as a class and acarbose in particular, are most useful in combatting PPHG and glucose variability across the spectrum of diabetes therapy, particularly in Asian patients. Together with their effects on incretin hormones and gut-microbiota AGIs can be considered beyond glycemic control as 'cardio-protective agents.'

Transcultural Diabetes Nutrition Algorithm: Brazilian Application

The prevalence of obesity, pre-diabetes, and type 2 diabetes (T2D) is increasing worldwide, especially in the developing nations of South America. Brazil has experienced an exponential increase in the prevalence of these chronic non-communicable diseases. The rising prevalence is probably due to changing eating patterns, sedentary living, and a progressive aging of the population. These trends and their underlying causes carry untoward consequences for all Brazilians and the future of Brazilian public health and the healthcare system. Lifestyle changes that include healthy eating (nutrition therapy) and regular physical activity (structured exercise) represent efficient inexpensive measures to prevent and/or treat the aforementioned disorders and are recommended for all afflicted patients. Regrettably, the implementation of lifestyle changes is fraught with clinical and personal challenges in real life. The transcultural Diabetes Nutrition Algorithm (tDNA) is a therapeutic tool intended to foster implementation of lifestyle recommendations and to improve disease-related outcomes in common clinical settings. It is evidence-based and amenable to cultural adaptation. The Brazilian Diabetes Association, Society of Cardiology and Ministry of Health guidelines for nutrition therapy and physical exercise were considered for the Brazilian adaptation. The resultant tDNA-Brazil and its underlying recommendations are presented and explained.

Cross-regional analysis of multiple factors associated with childhood obesity in India: a national or local challenge?

OBJECTIVE

To investigate obesogenic co-causing factors, promoting rise of weight in children, associated to local differences in India.

METHODS

Overall 1,680 children, aged 3-11 and balanced by gender, were recruited in school contexts distributed in seven major Indian cities. All children were weighted and measured in order to calculate their BMI. A validated cultural specific questionnaire was administered to children's parents for assessing socio-demographic data, eating habits, physical activity, etc. Furthermore children's brand awareness scores were computed in order to analyze their affiliation towards food-based advertisement. Descriptive statistics of frequencies, duration and intensity of the various factors were performed. Chi-square tests or Wilcoxon signed rank test were used for evaluating significance of differences in factors distribution across Indian cities.

RESULTS

Four factors, promoting rise of children's weight, were individuated as associated to urban differences, namely meal times consumed in the family, parents' BMI, brand awareness and physical activity. These aspects exercised a significant impact on children's body size in Kolkata and Chennai. Hyderabad and Mumbai, instead, were the cities where religion played some role in influencing children's weight gain.

CONCLUSIONS

Such findings underline the need to frame obesity as a situated phenomenon rather than a national problem. Health policies, implemented in treating and preventing obesity, should be therefore specifically focused on locally situated peculiarities.

Anti-Obesity Agents and the US Food and Drug Administration

Despite the growing market for obesity care, the US Food and Drug Administration (FDA) has approved only two new pharmaceutical agents-lorcaserin and combination phentermine/topiramate-for weight reduction since 2000, while removing three agents from the market in the same time period. This article explores the FDA's history and role in the approval of anti-obesity medications within the context of a public health model of obesity. Through the review of obesity literature and FDA approval documents, we identified two major barriers preventing fair evaluation of anti-obesity agents including: (1) methodological pitfalls in clinical trials and (2) misaligned values in the assessment of anti-obesity agents. Specific recommendations include the use of adaptive (Bayesian) design protocols, value-based analyses of risks and benefits, and regulatory guidance based on a comprehensive, multi-platform obesity disease model. Positively addressing barriers in the FDA approval process of anti-obesity agents may have many beneficial effects within an obesity disease model.

Is my kid out of size? Indian mothers' desirability bias in evaluation of their children's weight

OBJECTIVE

To quantify mothers' social desirability bias with respect to their children's weight in a cross-regional Indian setting.

METHODS

The OBEY-AD was a cross-sectional study which has been realized in 7 Indian cities (Bengaluru, Mumbai, Chennai, Hyderabad, Kolkata, New Delhi and Surat), enroling 1,680 children aged 3-11 y of which 50% were females. Children's BMI scores were computed, standardized according to WHO growth charts and categorized as Normal, Overweight, Obese and Underweight. Mothers were asked to judge the weight status of their children through an iconographic test, indicating the shape, which better mirrors the size of their kids. Socio-demographic data, especially employment, income and education, was accessed by administrating a cross-sectional questionnaire to the mothers, involved for the study.

RESULTS

Overall, 369 children resulted as obese or overweight (23.5%). Out of them, 75% (278) were not recognized as such by their mothers. Such figures range from up to 76% in Chennai and Surat down to 72% in Hyderabad, Kolkata, New Delhi and Mumbai. Overall agreement between perceived and desired weight status of children was very poor (p < 0.001). Surprisingly, overall 10% of overweight/obese children were considered as even too lean by their mothers. Misperception of children's weight status seemed to be significantly related to urban differences and socio-economic status.

CONCLUSIONS

This study quantifies the extent of the so-called social desirability bias, namely mother's unconscious attitude to adapt empirical evidence to more culturally legitimized ideal-types of what their children's weight status is expected to be. Its association with westernized representations of leanness as evaluation criteria for beauty has important policy implications.

Physical activity patterns among school children in India

OBJECTIVE

To assess the prevalence of physical activity and its relation with socio-demographic variables and eating habits among school-aged children in India.

METHODS

The study incorporated secondary analysis of anthropometric measurements and questionnaires on lifestyle and dietary habits of 1,680 school children aged between 3 and 11 y, obtained while carrying out the OBEY-AD project. The inventory contained questions about several variables concerning to physical activity, educational background, lifestyles and eating habits for both children and parents. Questions were organized along specific contents, which could be informative topics, picture choices and multiple answers choices.

RESULTS

Prevalence of inactivity was 21% and exhibited significant variations between cities. Physical activity was significantly associated to socio-economic status and consumption of fruits and vegetables. No association could be revealed with children's BMI.

CONCLUSIONS

Health-promotion interventions aimed at improving healthy lifestyles in Indian children should focus on population strata with low socio-economic status.

Transcultural diabetes nutrition algorithm (tDNA): Venezuelan application

Medical nutrition therapy (MNT) is a necessary component of comprehensive type 2 diabetes (T2D) management, but optimal outcomes require culturally-sensitive implementation. Accordingly, international experts created an evidence-based transcultural diabetes nutrition algorithm (tDNA) to improve understanding of MNT and to foster portability of current guidelines to various dysglycemic populations worldwide. This report details the development of tDNA-Venezuelan via analysis of region-specific cardiovascular disease (CVD) risk factors, lifestyles, anthropometrics, and resultant tDNA algorithmic modifications. Specific recommendations include: screening for prediabetes (for biochemical monitoring and lifestyle counseling); detecting obesity using Latin American cutoffs for waist circumference and Venezuelan cutoffs for BMI; prescribing MNT to people with prediabetes, T2D, or high CVD risk; specifying control goals in prediabetes and T2D; and describing regional differences in prevalence of CVD risk and lifestyle. Venezuelan deliberations involved evaluating typical food-based eating patterns, correcting improper dietary habits through adaptation of the Mediterranean diet with local foods, developing local recommendations for physical activity, avoiding stigmatizing obesity as a cosmetic problem, avoiding misuse of insulin and metformin, circumscribing bariatric surgery to appropriate indications, and using integrated health service networks to implement tDNA. Finally, further research, national surveys, and validation protocols focusing on CVD risk reduction in Venezuelan populations are necessary.

Transcultural diabetes nutrition algorithm: a malaysian application

Glycemic control among patients with prediabetes and type 2 diabetes mellitus (T2D) in Malaysia is suboptimal, especially after the continuous worsening over the past decade. Improved glycemic control may be achieved through a comprehensive management strategy that includes medical nutrition therapy (MNT). Evidence-based recommendations for diabetes-specific therapeutic diets are available internationally. However, Asian patients with T2D, including Malaysians, have unique disease characteristics and risk factors, as well as cultural and lifestyle dissimilarities, which may render international guidelines and recommendations less applicable and/or difficult to implement. With these thoughts in mind, a transcultural Diabetes Nutrition Algorithm (tDNA) was developed by an international task force of diabetes and nutrition experts through the restructuring of international guidelines for the nutritional management of prediabetes and T2D to account for cultural differences in lifestyle, diet, and genetic factors. The initial evidence-based global tDNA template was designed for simplicity, flexibility, and cultural modification. This paper reports the Malaysian adaptation of the tDNA, which takes into account the epidemiologic, physiologic, cultural, and lifestyle factors unique to Malaysia, as well as the local guidelines recommendations.

Diabetes-specific nutrition algorithm: a transcultural program to optimize diabetes and prediabetes care

Type 2 diabetes (T2D) and prediabetes have a major global impact through high disease prevalence, significant downstream pathophysiologic effects, and enormous financial liabilities. To mitigate this disease burden, interventions of proven effectiveness must be used. Evidence shows that nutrition therapy improves glycemic control and reduces the risks of diabetes and its complications. Accordingly, diabetes-specific nutrition therapy should be incorporated into comprehensive patient management programs. Evidence-based recommendations for healthy lifestyles that include healthy eating can be found in clinical practice guidelines (CPGs) from professional medical organizations. To enable broad implementation of these guidelines, recommendations must be reconstructed to account for cultural differences in lifestyle, food availability, and genetic factors. To begin, published CPGs and relevant medical literature were reviewed and evidence ratings applied according to established protocols for guidelines. From this information, an algorithm for the nutritional management of people with T2D and prediabetes was created. Subsequently, algorithm nodes were populated with transcultural attributes to guide decisions. The resultant transcultural diabetes-specific nutrition algorithm (tDNA) was simplified and optimized for global implementation and validation according to current standards for CPG development and cultural adaptation. Thus, the tDNA is a tool to facilitate the delivery of nutrition therapy to patients with T2D and prediabetes in a variety of cultures and geographic locations. It is anticipated that this novel approach can reduce the burden of diabetes, improve quality of life, and save lives. The specific Southeast Asian and Asian Indian tDNA versions can be found in companion articles in this issue of Current Diabetes Reports.
