まとめ
低筋力と腹部肥満の組み合わせであるダイナペニック腹部肥満は,高齢者の糖尿病リスクを大幅に増加させます. 腹部肥満だけでは リスクが高くなりますが 筋肉の強さが低いだけでは リスクは高くありません
科学分野:
- ゲロントロジー
- 代謝 健康
- 流行病学について
背景:
- 糖尿病は,特に高齢者の間で,世界的な健康上の懸念が高まっています.
- 以前の研究では,筋肉の弱さ (ダイナペニア) と腹部肥満と糖尿病のリスクの増加との間の個々の関連が示されています.
- ダイナペニアと腹部肥満が,中年および高齢者の糖尿病リスクに与える影響は,まだ十分に研究されていない.
研究 の 目的:
- ダイナペニアと腹部肥満と糖尿病の発症リスクとの関連を独立して調査する.
- ダイナペニック腹部肥満が高齢者群で糖尿病のシネジスティックリスクをもたらすかどうかを判断する.
主な方法:
- 中国保健・退職長期研究 (CHARLS) のデータ (2011-2020年) を利用した.
- 45歳以上の7934人の参加者を含めた.
- 手の握り力と腰周りの測定を組み合わせて,ダイナペニック腹部肥満を定義した.
- ディナペニア,腹部肥満,糖尿病リスクとの関連性を評価するために,Coxの比例リスクモデルを使用し,感度分析を行った.
主要な成果:
- ダイナペニックによる腹部肥満は,糖尿病のリスクの52%の増加と有意に関連していた (HR=1. 52).
- 腹部肥満だけでは糖尿病のリスクが54%増加しました (HR=1. 54).
- ダイナペニア単独では,糖尿病のリスク増加と統計的に関連していません (HR=1. 05).
結論:
- 腹部肥満と腹部肥満は,中年および高齢者の糖尿病の発症の重要な危険因子です.
- 腹部肥満をターゲットにすることは,ダイナペニアだけでは重要な独立した危険因子ではないため,高齢者の糖尿病予防に不可欠である可能性があります.

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...

Psychoneuroimmunology: Diabetes and Cancer

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Obesity
609
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Diabetes Mellitus: Type 2 and Gestational
2.9K
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...

Pathophysiology 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,...

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...
