Summary
Epigenetic age acceleration is linked to hearing loss in older adults, with significant sex differences observed. GrimAge acceleration (GrimAA) was associated with poorer hearing, especially in females.
Area of Science:
- Gerontology
- Epigenetics
- Audiology
Background:
- Hearing loss is a common age-related condition.
- Epigenetic age acceleration (EAA) is a potential biomarker for aging.
- Limited research exists on EAA and hearing loss, especially concerning sex differences.
Purpose of the Study:
- To investigate the association between EAA and hearing function in older adults.
- To examine sex differences in the relationship between EAA and hearing loss.
Main Methods:
- Analysis of data from the Health and Retirement Study (n=1755).
- Utilized five epigenetic clocks for EAA assessment.
- Multivariable regression models to assess EAA's link to hearing test scores and hearing loss.
Main Results:
- Phenotypic age acceleration, GrimAge acceleration (GrimAA), and methylation-based pace of aging were linked to lower hearing scores.
- GrimAA was associated with higher odds of hearing loss.
- These associations were more pronounced in females than males.
Conclusions:
- EAA may serve as a biomarker for age-related hearing loss.
- Sex differences in aging and hearing loss warrant further investigation.
- Epigenetic mechanisms could be targets for interventions to prevent hearing loss, particularly in women.

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Epigenetic Regulation
3.9K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Accelerators
291
Accelerators in concrete serve as admixtures to speed up the hardening process, enabling the concrete to achieve early strength faster. Although accelerators do not necessarily impact the time it takes concrete to set, they reduce this time in practice. A common accelerator is calcium chloride, which is particularly useful for hastening early strength development in cold weather or for rapid repair jobs that require quick heat generation after mixing.

Aging

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...

Average Acceleration
14.0K
The importance of understanding acceleration spans our day-to-day experiences, as well as the vast reaches of outer space and the tiny world of subatomic physics. In everyday conversation, to accelerate means to speed up. For instance, we are familiar with the acceleration of our car; the harder we apply our foot to the gas pedal, the faster we accelerate. The greater the acceleration, the greater the change in velocity over a given time. Acceleration is widely seen in experimental physics. In...
