Summary
Supercentenarians (aged ≥110 years) are rare, but data on their global distribution is limited. Japan has the most, while Puerto Rico may have the highest prevalence among those reaching extreme longevity.
Area of Science:
- Gerontology
- Demography
- Human Longevity Research
Background:
- The global population is aging, with centenarians representing successful aging.
- Supercentenarians (SCs; ≥110 years) are a scientifically significant subgroup of extremely long-lived individuals.
- Data on the worldwide distribution of supercentenarians are scarce.
Purpose of the Study:
- To investigate the current worldwide distribution of supercentenarians.
- To identify countries with notable supercentenarian populations or prevalence.
Main Methods:
- Analysis of available global data on supercentenarian populations.
- Comparison of supercentenarian numbers and prevalence rates across countries.
- Consideration of demographic factors and potential data limitations.
Main Results:
- Japan currently has the highest number of living supercentenarians.
- Puerto Rico may exhibit the highest prevalence of supercentenarians among individuals aged ≥95 years (approx. 1 per 10,000).
- Data for Puerto Rico requires cautious interpretation due to population size and methodological constraints.
Conclusions:
- Further investigation into the genetic and lifestyle factors of supercentenarians is warranted.
- Understanding supercentenarians can reveal mechanisms underlying extreme human longevity.
- Accurate global data collection on supercentenarians is crucial for future research.

1.1K
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...

01:27Pharmacodynamics in Geriatric Patients: Effects of Age
349
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
365
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...

00:57Population Growth
29.8K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism
374
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...

376
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...
