4 天之前 · How does chronological aging differ from biological aging? Read on to learn more about the differences, as well as tips for healthy aging.

2023年7月24日 · What is biological aging? The basic idea behind biological aging is that aging occurs as you gradually accumulate damage to various cells and tissues in the body. Also known as physiological...

2024年7月25日 · There is also an important difference between how old someone is, known as chronological age, and the overall state of someone’s body, known as biological age. This distinction may help demystify the aging process and allow you to take a more empowered, holistic approach to your health.

2025年1月31日 · A person's chronological and biological ages may differ. Chronological age is the number of years a person has been alive, while biological age refers to how old their cells and tissues are based on evidence in their DNA.

Biological aging is described as a gradual or progressive deterioration of health, including the functional impairment of physiological systems and disease, leading ultimately to death [17].

Current research focuses on measuring the pace of aging to identify individuals who are “aging faster” to test and develop interventions that could prevent or delay the progression of multimorbidity and disability with aging.

2025年2月13日 · A new study draws a line between random genetic mutations and predictable epigenetic changes used to measure biological aging.

Grading of the degree of frailty and measuring biomarkers are distinct methods of measuring biological age. This review compares these strategies for estimating biological age for clinical purposes. The degree of frailty predicts susceptibility to adverse outcomes independently of chronological age.

2023年11月6日 · First, biological age is a comprehensive concept that is not only related to lifespan but also other health-related outcomes, including quality of life. Few current clocks consider events such as ageing-related lifestyle changes (eg, the requirement of medicine prescription and hospital admission).
