Summary
Colorectal cancer (CRC) screening in Koreans is linked to healthcare access and beliefs. Physician recommendations and reduced barriers significantly boost screening rates for fecal occult blood tests and colonoscopies.
Area of Science:
- Public Health
- Cancer Epidemiology
- Health Behavior Research
Background:
- Colorectal cancer (CRC) presents a significant health challenge in South Korea, with persistently high incidence and mortality rates.
- Despite the National Cancer Screening Program, understanding CRC screening behavior determinants is crucial for intervention development.
Purpose of the Study:
- To investigate the associations between sociodemographic factors, healthcare access, knowledge, health beliefs, and cultural beliefs with CRC screening behaviors in the Korean population.
- To identify key predictors influencing adherence to fecal occult blood tests (FOBT) and colonoscopies.
Main Methods:
- A cross-sectional survey was conducted among 648 Koreans aged 50+ at average CRC risk.
- Data collection involved questionnaires on sociodemographics, healthcare access, knowledge, beliefs, and screening behaviors.
- Statistical analysis included descriptive statistics, bivariate, and multivariate logistic regression.
Main Results:
- Physician recommendation and perceived barriers were strong predictors for FOBT adherence.
- Physician recommendation, usual source of care, perceived benefits, and barriers influenced colonoscopy use.
- Perceived barriers decreased screening likelihood by 57%, while perceived benefits doubled colonoscopy odds.
Conclusions:
- CRC screening participation in Koreans is significantly associated with healthcare access and health belief components.
- Enhancing physician recommendations and mitigating perceived barriers are vital for improving screening rates.
- Culturally tailored education and expanded colonoscopy services are recommended for better CRC screening adherence.

00:54What is Behavior?
10.3K
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

01:28Behaviorism
5.5K
The field of behaviorism was pioneered by figures such as Ivan Pavlov, John B. Watson, and B.F. Skinner fundamentally shifted the focus of psychology to the observable and controllable aspects of human and animal behavior. This shift marked a critical evolution in the discipline, emphasizing scientific rigor and experimental methodology.
The core premise of behaviorism is its focus on observable behavior rather than internal thoughts or feelings. This approach argues that true scientific...

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Behavior therapy incorporates diverse techniques rooted in classical conditioning principles to address maladaptive behaviors and anxiety disorders. These methods aim to reduce avoidance behaviors, foster adaptive coping mechanisms, and alter associations between stimuli and responses, making them effective in a wide range of therapeutic contexts.

01:21Plastic Behavior
585
A material's elastic behavior is characterized by the disappearance of stress once the load is removed, allowing the material to return to its original state. However, when stress surpasses the yield point, yielding commences, marking the onset of plastic deformation or permanent set. This change from elastic to plastic behavior is influenced by the peak stress value and the duration before the load is removed. An intriguing observation occurs when a specimen is loaded, unloaded, and...

01:09Electron Behavior
13.6K
Electrons are negatively charged subatomic particles attracted to and orbit around the positively-charged nucleus of an atom. They reside in spaces associated with energy levels called shells and are further organized into subshells and orbitals within each shell.
Electrons Orbit the Nucleus
Electrons are found in specific locations outside of the nucleus. The shell in which an electron resides indicates the general energy level of the electron: those closer to the nucleus have less energy,...
