Summary
Migration significantly increases obesity and type 2 diabetes mellitus (T2DM) risk due to environmental shifts like urbanization and lifestyle changes. Ethnic susceptibility and gene-environment interactions play key roles in these escalating global health challenges.
Area of Science:
- Public Health
- Epidemiology
- Genetics
Background:
- Global migration patterns are increasing.
- Obesity and type 2 diabetes mellitus (T2DM) prevalence is escalating worldwide.
- Migrants often experience shifts in environment and lifestyle.
Purpose of the Study:
- To review the impact of migration on obesity and T2DM incidence and prevalence across diverse ethnic groups.
- To analyze the determinants contributing to these health outcomes in migrant populations.
- To understand the role of environmental factors in the risk escalation of obesity and T2DM.
Main Methods:
- Literature review synthesizing existing research on migration, obesity, and T2DM.
- Analysis of prevalence data across different ethnic groups and migration pathways.
- Examination of contributing factors including nutrition, physical activity, and gene-environment interactions.
Main Results:
- Obesity and T2DM risk increases with urbanization and affluence in migrant populations.
- Specific ethnic groups, like South Asians, show heightened predisposition to T2DM.
- Environmental factors such as nutrition transition and physical inactivity are key determinants.
Conclusions:
- Environmental factors critically influence the increased risk of obesity and T2DM in migrants.
- Urbanization, lifestyle changes, and ethnic susceptibility are significant contributors.
- Further research is needed to understand the roles of stress and unknown factors.

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...
01:22Diabetes 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...
01:24Type 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.
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...

01:15Diabetes: Symptoms, Diagnosis, and Complications
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is based on...
01:20Pathophysiology of Diabetes
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
