Clinical Interventions in Aging
|March 19, 2020
Summary
Elderly inpatients who are underweight or have abdominal obesity face a higher risk of frailty. Low skeletal muscle mass is a key indicator of frailty in older adults.
Area of Science:
- Gerontology
- Clinical Medicine
- Body Composition Analysis
Background:
- Frailty is a significant concern in elderly populations, impacting health outcomes and healthcare utilization.
- Understanding the relationship between body composition and frailty is crucial for developing targeted interventions.
Purpose of the Study:
- To investigate the association between various body composition parameters and the prevalence of frailty in elderly inpatients.
- To identify specific body composition phenotypes linked to frailty in this demographic.
Main Methods:
- A cross-sectional study involving 656 elderly inpatients (aged ≥65 years) was conducted.
- Body composition was assessed using bioimpedance analysis (BIA), measuring parameters like skeletal muscle mass and body fat mass.
- Frailty was evaluated using the Clinical Frailty Scale (CFS).
Main Results:
- Frailty was identified in 43.9% of the participants.
- Frail individuals exhibited higher body fat mass and waist circumference, while non-frail individuals had greater skeletal muscle mass and fat-free mass.
- Underweight (BMI <18.5 kg/m²), high waist circumference, and high body fat mass were associated with an increased risk of frailty.
Conclusions:
- Frailty in elderly Chinese inpatients is characterized by a body composition phenotype including underweight, high waist circumference, low skeletal muscle mass, and high body fat mass.
- Interventions targeting underweight, abdominal obesity, and sarcopenic obesity may help mitigate frailty in older adults.

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...

01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
146
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...

01:15Drug Dosing: Geriatric Patients
168
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...

01:19The Effect of Aging on Tissues
3.1K
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...

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
190
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...

141
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...
