Summary
Regular physical activity (PA) significantly reduces mortality in type 2 diabetes (T2D) patients. Greater intensity and duration of exercise are linked to lower risks of all-cause, cancer, and cardiovascular disease mortality.
Area of Science:
- Endocrinology
- Public Health
- Epidemiology
Background:
- Physical activity (PA) is known to reduce diabetes mortality.
- Previous studies relied on imprecise self-reported data, potentially limiting recommendations.
- Objective measurement is crucial for accurate PA assessment in type 2 diabetes (T2D).
Purpose of the Study:
- To investigate the association between objectively measured PA duration and intensity with mortality in T2D patients.
- To provide evidence-based insights for refining clinical guidelines on PA for T2D management.
Main Methods:
- Prospective cohort study of 19,624 individuals with T2D from the UK Biobank.
- PA measured objectively using wrist-worn accelerometers over 7 days.
- Median follow-up of 6.9 years to assess mortality outcomes.
Main Results:
- L-shaped associations observed between PA duration and all-cause/cancer mortality risks.
- Negatively linear association found between PA duration and cardiovascular disease mortality risk.
- Significant proportions of deaths attributed to low levels of light (12.7%), moderate (15.8%), and vigorous (22.3%) PA.
Conclusions:
- Objectively measured PA duration and intensity are strongly associated with mortality in T2D.
- Clinical guidelines should emphasize the benefits of increased PA duration and intensity for T2D patients.
- Findings support the value of promoting higher levels of physical activity for improved survival in type 2 diabetes.

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...

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...

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...

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...
