Summary
Fatigue in older adults is linked to functional capacity, psychological well-being, and social support. Psychosocial factors significantly influence fatigue in advanced age.
Area of Science:
- Gerontology
- Psychology
- Public Health
Background:
- Fatigue is a prevalent complaint in older adults, yet its nature and correlates in advanced age remain under-researched.
- Limited understanding exists regarding the multifaceted contributors to fatigue in the oldest-old population.
Purpose of the Study:
- To investigate the relationship between functional, psychological, and situational factors and fatigue in octogenarians and centenarians.
- To identify key predictors of fatigue in the oldest-old population.
Main Methods:
- Utilized a multidimensional fatigue scale and assessed functional capacity (self-rated health, ADLs), psychological well-being (affect), and situational factors (social network, support).
- Employed blocked multiple regression and structural equation modeling to analyze predictors and residential differences in fatigue.
Main Results:
- Self-rated health, instrumental activities of daily living, positive and negative affect, and social support significantly predicted fatigue.
- Residential status (long-term care vs. private home) showed significant differences in factors related to fatigue.
Conclusions:
- Fatigue in advanced age is influenced by a complex interplay of functional, psychological, and social factors.
- Psychosocial aspects are crucial considerations, extending beyond physical symptoms, in understanding and managing fatigue in the elderly.

01:21Fatigue
Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...
01:27Pharmacodynamics in Geriatric Patients: Effects of Age
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...
01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism
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...
01:26Aging
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...

01:15Drug Dosing: Geriatric Patients
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...
01:18Factors Affecting Illness
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness, disability,...
