概括
每周进行一到两天的中度至强度体力活动 (MVPA),称为周末战士模式,可显著降低2型糖尿病的风险. 这种模式提供了与常规活动相比较的保护,强调了积累足够的MVPA的重要性.
科学领域:
- 运动生理学和代谢疾病研究.
- 公共卫生和预防医学策略.
- 慢性疾病和生活方式因素的流行病学.
背景情况:
- 越来越多的证据将体育活动的持续时间与2型糖尿病 (T2D) 发病率联系起来.
- 影响的影响的影响.
- 周末的战士 周末的战士
- 对T2D风险的 (WW) 模式尚不清楚.
研究的目的:
- 调查不同体力活动模式 (包括WW模式) 与T2D风险之间的关联.
- 为了利用客观的,设备测量的身体活动数据进行精确的模式分类.
- 为了比较与WW模式相关的T2D风险降低与定期体育活动.
主要方法:
- 预期队列研究设计与设备测量的体力活动数据.
- 将参与者分为不活跃的,活跃的WW (≥150分钟MVPA在1-2天内≥50%),和活跃的常规模式.
- 使用考克斯比例危险模型分析T2D发病率,调整了混因子.
主要成果:
- 在7.9年的时间里,1972名参与者患上了T2D.
- 活跃的WW和活跃的正规模式都显示了T2D风险的显著降低 (HR分别为0.64和0.56).
- 增加中度至强度体力活动 (MVPA) 的持续时间,在两个活跃组中逐渐降低了T2D风险.
结论:
- 将体力活动集中在每周一到两天 (WW模式) 提供了与更加均分布的活动相似的T2D保护.
- 超过当前的体育活动指南可能为T2D预防提供了更大的好处.
- WW模式是减少T2D发病率的可行策略.

Diabetes Mellitus: Type 2 and Gestational
2.1K
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...

Diabetes: 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...

Carbohydrate 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...
