Validation of a Psychosocial Intervention on Body Image in Older People: An Experimental Design
Published on: May 31, 2021
Aging and health.
Summary
The global population of elderly individuals is rising, increasing the risk of widespread chronic disease and disability. Urgent research is crucial to improve aging, prevent illness, and enhance quality of life for seniors.
Area of Science:
- Gerontology
- Public Health
- Chronic Disease Epidemiology
Background:
- Global life expectancy is increasing, leading to a larger elderly population.
- Current disability rates, if unchanged, will exacerbate resource strain.
- Aging populations face significant risks of chronic disease and disability.
Purpose of the Study:
- To address the growing challenge of chronic disease and disability in aging populations.
- To advocate for immediate and substantial research into aging and related conditions.
- To ensure a high quality of life for the elderly despite increasing life spans.
Main Methods:
- Review of demographic trends and projected population changes.
- Analysis of the relationship between aging, disability, and resource allocation.
- Identification of research priorities in gerontology and chronic disease.
Main Results:
- A significant increase in the elderly population is predicted globally.
- Without intervention, chronic disease and disability will burden a substantial population segment.
- Current resources are insufficient to meet the projected demands.
Conclusions:
- Urgent, substantial research is imperative to understand aging processes.
- Identifying causes of chronic disease is key to developing preventive strategies.
- Developing effective treatments and rehabilitation is essential for elderly quality of life.

The Effect of Aging on Tissues
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...
Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Drug 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...
Pharmacodynamics 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...
Cognitive Development During Adulthood
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...
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...
