Primary Healthcare Services

1.9K
Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.

Levels of Health Promotion and Illness Prevention

14.1K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Preventive Healthcare Services

1.8K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

439
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

There are various healthcare agencies in the United States—some of which are managed by religious institutions and others by different government branches.
Parish nursing is a growing specialty nursing profession that focuses on holistic healthcare, health promotion, and illness prevention. It blends professional nursing practice with a health ministry, focusing on health and healing within the context of a Christian community.

Methods Of Healthcare Delivery System01:26

Methods Of Healthcare Delivery System

3.9K
At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...

Summary
This summary is machine-generated.

This pilot study found that greater Chinese cultural acculturation may be linked to better cognition in older Chinese Americans. Immigration experiences, like age at arrival, may also influence cognitive health in this population.

Area of Science:

  • Gerontology
  • Neuroscience
  • Public Health

Background:

  • Limited research exists on Alzheimer's Disease and Related-Dementias (ADRD) risk factors in older Chinese Americans.
  • Immigration experiences are known to affect cognition in diverse older adult populations.
  • This study addresses the gap in understanding ADRD risk within the Chinese American community.

Purpose of the Study:

  • To investigate the association between immigration experiences and cognitive function in older Chinese Americans.
  • To explore how acculturation, age at immigration, and duration of stay in the U.S. relate to cognition.
  • To lay the groundwork for future research on dementia risk in this underrepresented group.

Main Methods:

  • Pilot study involving 88 older Chinese Americans (normal cognition or mild cognitive impairment).
  • Data collected on acculturation, age at immigration, and duration of immigration.
  • Cognitive function assessed using the Clinical Dementia Rating (CDR) and Montreal Cognitive Assessment (MoCA).
  • Linear regression models controlled for age, gender, education, and socioeconomic status.

Main Results:

  • Greater Chinese cultural acculturation showed a marginal association with better cognitive performance (higher MoCA, lower CDRSOB).
  • Younger age at immigration and longer duration of immigration were tentatively linked to poorer cognition, though not statistically significant.
  • Preliminary evidence suggests immigration experiences impact cognitive health in this demographic.

Conclusions:

  • Immigration experiences appear to be related to cognitive function in older Chinese Americans.
  • Larger sample sizes are required to confirm these preliminary findings.
  • Further research is crucial to understand immigration's role in AD/ADRD risk for this population.
