Summary
Sarcopenia, or muscle loss in older adults, affects 72.2% of institutionalized individuals. Male sex and thinness increase risk, while obesity appears protective, highlighting the need for targeted interventions.
Area of Science:
- Gerontology
- Geriatrics
- Public Health
Background:
- Sarcopenia significantly impacts elderly health, increasing disease and mortality risks.
- It diminishes functional capacity and quality of life in older adults.
Purpose of the Study:
- To determine the prevalence of sarcopenia among institutionalized elderly.
- To identify factors associated with sarcopenia in this population.
Main Methods:
- Cross-sectional study of 216 elderly individuals (≥ 60 years) in long-term care facilities in Salvador-Bahia, Brazil.
- Sarcopenia identified using the skeletal muscle index.
- Poisson regression with robust variance analyzed associations with gender, age, institutionalization duration, institution type, BMI, and functional capacity.
Main Results:
- Prevalence of sarcopenia was 72.2%.
- Associated factors included male sex (PR = 1.33) and thinness (PR = 1.29).
- Obesity showed a protective association (PR = 0.37).
Conclusions:
- High prevalence of sarcopenia observed in institutionalized elderly, particularly men.
- Thinness is linked to greater muscle reserve impairment.
- Obesity may offer a protective effect against sarcopenia in this group.

01:29Bone 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...

01:19The Effect of Aging on Tissues
4.0K
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...

01:27Pharmacodynamics in Geriatric Patients: Effects of Age
288
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
303
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...

01:18Factors Affecting Illness
5.5K
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,...

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
292
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...
