Summary
Preserving intrinsic capacity (IC) in older adults is vital. Lower income and more comorbidities negatively impact IC, while more surgeries and good balance positively influence it, guiding preventive gerontology strategies.
Area of Science:
- Gerontology
- Public Health
- Aging Research
Background:
- Intrinsic capacity (IC) encompasses physical and mental abilities crucial for functional aging.
- Assessing IC is essential for preventive gerontology strategies.
- Community-dwelling older adults in social groups in Brazil were the focus.
Purpose of the Study:
- To evaluate factors associated with good intrinsic capacity (IC) in community-dwelling older adults.
- To identify predictors of preserved IC for targeted interventions.
- To inform preventive strategies in gerontology.
Main Methods:
- Cross-sectional study design.
- Assessment of the 5 domains of intrinsic capacity using validated instruments.
- Analysis of associations between total IC score and sociodemographic, health, and functional variables.
Main Results:
- Half of the 170 participants (mean age 72.3 years) demonstrated preserved IC.
- Low income (OR 0.026) and multiple comorbidities (OR 0.691) were negatively associated with IC.
- Higher number of surgeries (OR 1.326) and good balance (OR 1.417) were positively associated with IC.
Conclusions:
- Income, comorbidities, surgical history, and balance significantly influence intrinsic capacity in older adults.
- Findings support the development of targeted interventions to promote IC preservation.
- Integrating IC assessment into healthcare services is recommended for proactive aging support.

Respiratory capacities are crucial indicators of lung function, representing the maximum amount of air an individual's respiratory system can handle during various breathing phases.
One key metric is the Inspiratory Capacity (IC), which represents the maximum amount of air that can be inhaled with full effort. IC is calculated by summing the tidal volume and inspiratory reserve volume, typically ranging from 2.4 to 3.6 liters.
The Functional Residual Capacity (FRC) represents the air in the...

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

5.1K
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.

01:17Factors Affecting Activity Coefficient
1.5K
The extended Debye-Hückel equation indicates that the activity coefficient of an ion in an aqueous solution at 25°C depends on three partially interdependent properties: the ionic strength of the solution, the charge of the ion, and the ion size.
The activity coefficient value for an ion is close to one when the solution has almost zero ionic strength, i.e., when the solution shows close to ideal behavior. As the ionic strength of the solution increases from 0 to 0.1 mol/L, a...

Lifestyle factors play a critical role in maintaining overall health and preventing chronic diseases. Key elements, such as regular physical activity, a nutritious diet, and abstinence from smoking, can significantly enhance physical, mental, and emotional well-being while reducing the risk of several life-threatening conditions.
