Summary
Dedicated nutrition interventions show promise for improving glycemic control in Type II diabetes (T2D) patients in low- and middle-income countries (LMICs). Further research with standardized reporting is needed to optimize these strategies.
Area of Science:
- Public Health
- Nutrition Science
- Endocrinology
Background:
- Rising incidence of Type II Diabetes (T2D) in low- and middle-income countries (LMICs).
- Nutrition interventions offer a potentially low-cost, low-burden approach to glycemic control.
- Systematic review to assess dedicated nutrition interventions for T2D in LMICs.
Purpose of the Study:
- To systematically review and analyze dedicated nutrition interventions for Type II Diabetes (T2D) in low- and middle-income countries (LMICs).
- To evaluate the effectiveness of these interventions on glycemic control.
- To identify research gaps and areas for future study.
Main Methods:
- Systematic literature search of PubMed, ProQuest, and Scopus databases.
- Inclusion criteria applied to 6778 unique abstracts, resulting in 37 publications (38 interventions).
- Data extraction on intervention characteristics, participant demographics, and outcomes.
Main Results:
- Interventions conducted across diverse LMICs, involving 2950 participants (55% women).
- Significant reductions observed in glycated hemoglobin (8.6% to 7.4%) and fasting glucose (172 to 135 mg/dL).
- High adherence (87%) but significant variability in intervention parameters and incomplete reporting.
Conclusions:
- Nutrition interventions demonstrate significant potential for improving glycemic control in T2D patients within LMICs.
- Limited research exists specifically within low-income countries.
- Standardized reporting and further research are crucial for developing evidence-based strategies.

01:22Diabetes Mellitus: Type 2 and Gestational
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
01:22Diabetes Mellitus: Overview and Type I Subtype
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

01:15Diabetes: Management and Pharmacotherapy
The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.

01:26Type II Diabetes I: Introduction
Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...
01:36Carbohydrate Metabolism
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...

01:24Type II Diabetes II: Pathophysiology
PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
