- ゲロントロジーと心臓血管科学
- 老化のバイオマーカー
- 公衆衛生と疫学
背景:
- 加速した生物学的老化は高血圧 (HTN) と心血管疾患 (CVD) のリスクの増加と関連しています.
- 健康からHTN,CVD,および生物学的老化による死亡率へのダイナミックな進行は,さらなる調査を必要とします.
- これらの移行における中間病状の役割を理解することは極めて重要です.
研究 の 目的:
- 健康,HTN,CVD,および死亡率の間の移行に加速された生物学的老化の影響を調査する.
- 生物学的老化を評価するために,表型年齢 (PhenoAge) とKlemera-Doubal方法の生物学的年齢 (KDM-BA) を利用する.
- 心血管疾患の進行における中間疾患の作用を評価する.
主な方法:
- 英国バイオバンク参加者136,614人の分析で,最初はHTNとCVDがありませんでした.
- PhenoAgeとKDM-BAを用いた加速生物学的老化の評価
- 病気の進行経路を評価するために,複数の状態モデルとメディエーション分析を適用する.
主要な成果:
- 急速な生物学的老化 (PhenoAgeとKDM- BA) は,HTNとCVDの発症リスクを大幅に増加させた.
- 生物学的加齢の加速は,HTNからCVDへの移行のリスクの増加と関連していました.
- 加速した生物学的老化は,健康状態,HTN,CVDにおける死亡率の有意な予測因子であり,中間疾患は主要な媒介者であった.

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

01:19The Effect of Aging on Tissues
2.4K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

12.4K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
