まとめ
COVID-19の感染は,肥満,肥満,または2型糖尿病の高齢者の骨粗鬆症のリスクを高めます. このリスクは時間とともに上昇し,感染後4年でピークに達し,少なくとも6年間持続します.
科学分野:
- 骨の健康に関する研究
- 感染症の影響
- 高齢者医療
背景:
- COVID-19は,特に肥満や糖尿病の高齢者 (≥50歳) の骨の健康に悪影響を及ぼす可能性があります.
- これらの症状は 骨の質を低下させ 脆弱性を高めます
- COVID-19の長期的な骨の健康への影響を理解することは,リスクのある集団にとって極めて重要です.
研究 の 目的:
- COVID-19 と長期的な骨の健康に関する関連性を調査する.
- 骨粗鬆症の新規発症 骨折や骨の密度低下を 具体的には調べています
- 肥満や2型糖尿病の高齢者を対象に
主な方法:
- 北米とヨーロッパの141の医療機関からのTrinetXデータを利用した遡及コホート研究.
- COVID-19患者 (年齢 ≥50,肥満,またはT2DM) と非COVID-19対照群の傾向スコアの一致.
- 既存の骨の疾患,骨折,または他の関連する併発症を有する個人を除外する. コックス回帰分析が適用された.
主要な成果:
- COVID-19は,感染後3年および6年の骨粗鬆症のリスクの有意な増加と関連していました.
- 感受性分析は,より長い遅延時間 (1~4年後の感染) で,徐々にリスクが増加していることを明らかにした.
- サブグループ分析では,異なる人口統計学および臨床的特徴における一貫した傾向が示された.
結論:
- COVID-19は,過体重,肥満,または2型糖尿病の高齢者の長期的な骨粗鬆症のリスクの増加と独立して関連しています.
- COVID-19 の後,骨粗鬆症を発症するリスクは時間とともに増大し,感染後 4 年ほどでピークに達します.
- これらの発見は,脆弱な集団におけるCOVID-19の継続的な有害な影響を強調しています.

3.9K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

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...

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...

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...

01:25Role of Vitamins in Maintaining Bone Health
3.6K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Stress often leads to unhealthy habits like smoking, excessive drinking, and overeating, which offer short-term relief but ultimately increase long-term health risks. These behaviors create a cycle that temporarily lowers stress levels but can result in severe long-term health consequences. Breaking these habits is essential to reduce the risk of chronic diseases and improve overall well-being. Three primary changes that support better health include quitting smoking, reducing alcohol intake,...
