- 肥満は,COVID-19の重症性と合併症を悪化させる既知の危険因子です.
- 肥満がCOVID-19のアウトカムに与える特定の影響を理解することは,効果的な管理に不可欠です.
研究 の 目的:
- COVID-19患者の臨床的重症度,肺関わり,入院死亡率に対する肥満の影響を評価する.
- 重度のCOVID-19疾患の独立予測要因を特定する.
主な方法:
- 3005人の入院COVID-19患者 (2020年1月〜2023年3月) の遡及コホート研究.
- 肥満 (体量指数 ≥30 kg/ m2) によって層分けされた患者
- 分析には,臨床的,併発性,イメージング,研究室,ワクチン接種データが含まれ,多変量回帰およびグラデーション増強モデルが使用されました.
主要な成果:
- 肥満患者は重度のCOVID-19 (31.7%対22.4%) と広範な肺損傷 (27.9%対22.0%) の割合が高くなりました.
- 肥満は重症の相対リスクが1. 41であり,肺の関わりが> 50%の相対リスクが1. 27であった.
- 特に肥満でない個体では,65歳以上の年齢が最も強い死亡率の予測因子でした.
結論:
- 肥満は,重度のCOVID-19および肺機能障害の独立した予測因子です.
- 臨床管理と公衆衛生の介入において,肥満に基づくリスクの階層化を支持しています.

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

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...

01:20Chronic Obstructive Pulmonary Disease-I: Introduction
2.9K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
