Obesity01:24

Obesity

1.4K
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Cognitive Dissonance01:38

Cognitive Dissonance

37.5K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Drug Dosing: Obese Patients

In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Cognition and Behavior01:23

Cognition and Behavior

383
Social psychology examines the complex interplay between individual mental processes and social interactions. Historically, the field was divided into two domains: social behavior and social cognition. Researchers focusing on social behavior analyzed actions within social contexts, such as conformity, aggression, or cooperation. Meanwhile, social cognition researchers investigated how people perceive, interpret, and mentally represent their social environments. However, modern perspectives no...

Cognitive Learning01:21

Cognitive Learning

1.2K
Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...

Language and Cognition01:27

Language and Cognition

804
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Area of Science:

  • Gerontology
  • Neuroscience
  • Public Health

Background:

  • Sarcopenia and obesity independently impair health and cognitive function.
  • The combined effect of sarcopenia and obesity (sarcopenic obesity) poses a significant threat to cognitive health.
  • Understanding the impact of sarcopenic obesity on cognition is crucial for aging populations.

Purpose of the Study:

  • To investigate the association between sarcopenic obesity and cognitive performance.
  • To examine the effects of sarcopenia and obesity, individually and combined, on global and subdomain cognitive functions.
  • To identify potential indicators for cognitive impairment in older adults.

Main Methods:

  • Cross-sectional analysis of community-based aging and memory studies.
  • Inclusion of 353 participants (average age 69 years) with comprehensive measurements.
  • Assessment of cognitive function (global and subdomain), functional status, and body composition.

Main Results:

  • Sarcopenic obesity showed the strongest association with lower global cognitive performance.
  • Sarcopenia was also significantly linked to reduced global cognition, while obesity alone showed a non-significant trend.
  • Executive function and orientation were identified as cognitive domains most affected by sarcopenic obesity and sarcopenia.

Conclusions:

  • Sarcopenia and sarcopenic obesity serve as clinical indicators of probable cognitive impairment.
  • Interventions focused on strength enhancement and obesity prevention may benefit at-risk older adults.
  • Maintaining physical function is key to preserving cognitive health in aging individuals.
