感染前の症状と機能的状態による長期のCOVIDリスク:All of Us Research Programからのデータに関する遡及的なコホート研究
medRxiv : the preprint server for health sciences
|August 20, 2025
まとめ
感染前に既に存在していた症状と精神的健康状態が悪化すると,長期COVIDのリスクが増加します. ロング・COVIDは,既往症状のある人でも重要な健康変化であり,機能的状態の評価の必要性を強調しています.
科学分野:
- 医学研究
- 公衆衛生
- 流行病学について
背景:
- 7百万人以上のアメリカ人は,COVID-19後の長期にわたる健康問題を経験しています.
- ガイドラインでは,機能的状態を長期COVID診断に含めることを示唆しているが,証拠は限られている.
- この研究では,長期COVID発症と機能状態の評価の実現可能性に影響を与える感染前の要因を調査しています.
研究 の 目的:
- 感染前の症状と機能的状態に基づいて,長期間COVIDを発症する調整された確率を探る.
- 電子医療記録を使用して感染前の機能的状態を推定する可能性を評価する.
- リスク要因を理解することで,長期COVIDの診断基準を明らかにする.
主な方法:
- All of Us CDR 7.0データベースを用いた遡及的なコホート研究.
- COVID-19の歴のある米国の成人を含め,2022年7月までの健康記録と調査データを分析した.
- 感染前 (5 年前) の症状と機能的状態を検査し,共変数を調整する.
主要な成果:
- N = 65,464人の参加者が対象となる基準を満たし,40,655人が長期的なCOVID症状を発症した.
- 長いCOVIDの確率は,感染前の自己評価の低い精神的健康 (AOR=1.14) と高い症状の負担と相関する.
- 単一の感染前の症状,自己評価された身体能力,または文書化された機能障害と長期COVIDの確率との間に有意な関連性が見つかりませんでした.
結論:
- 病前症状の負担が高く,自己評価の低い精神的健康は,長期のCOVIDの確率の増加と関連しています.
- 長期のCOVIDは,以前の状態であっても,健康と機能の著しい低下を意味します.
- 統合された電子医療記録を利用することで,感染前の機能的状態を推定し,長期のCOVID診断に役立ちます.

Stages of Infection
58.9K
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Factors Affecting the Risk of Infection
12.2K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
2.9K
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.

COPD: Pathogenesis and Clinical Features
512
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...

Classification of Illness
7.9K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
