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 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...

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.

Neighborhood walkability is linked to better attention in older adults and those with dementia. Higher walkability also protected brain structure in cognitively unimpaired individuals as they aged.

Area of Science:

  • Neuroscience
  • Gerontology
  • Urban Planning

Background:

  • Physical activity supports cognitive function and brain health in aging.
  • Neighborhood walkability, a measure of pedestrian-friendliness, may promote physical activity.
  • Associations between walkability, executive functions, and brain structure were examined in older adults.

Purpose of the Study:

  • To evaluate the association of neighborhood walkability with executive functions and gray matter (GM) volumes.
  • To investigate the interaction between walkability and age in cognitively unimpaired (CU) individuals and those with mild cognitive impairment (MCI) or dementia.

Main Methods:

  • 1543 participants (CU, MCI, dementia) from the UBRAIN study were included.
  • Executive functions and MRI-based GM volumes were assessed.
  • Walkability was measured using an index of 8 factors within a 100m radius of residences.

Main Results:

  • Higher walkability correlated with better attention (WAIS Digits forward scores) in the full sample.
  • This association was significant in CU and dementia groups, but not MCI.
  • In CU individuals, increased walkability mitigated age-related decline in temporo-parietal GM volumes.

Conclusions:

  • Living in walkable neighborhoods is associated with better attention in CU individuals and dementia patients.
  • Walkability may act as a protective factor against cognitive aging and dementia.
  • Further research is needed to confirm if physical activity mediates this protective effect.
