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.
In 1978, international leaders convened in Alma-Ata, Kazakhstan, for what would be a pivotal event in global health. The Alma-Ata Declaration was the first to call...

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. Parish nurses serve as health educators, referral sources,...

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.

Long sleep duration and wake after sleep onset (WASO) are linked to cognitive decline, particularly in executive function and attention. These findings highlight the importance of assessing specific cognitive domains in sleep research.

Area of Science:

  • Gerontology
  • Sleep Science
  • Neuroscience

Background:

  • Poor sleep and circadian rhythm disruptions are linked to cognitive decline and dementia risk.
  • Limited research exists on objective sleep measures, rest-activity rhythms (RAR), and specific cognitive domains.

Purpose of the Study:

  • To investigate associations between objective sleep metrics, RAR parameters, and cognitive function in older adults.
  • To examine how sleep and circadian rhythm variables relate to executive function, attention, memory, and language.

Main Methods:

  • Utilized 7-day wrist actigraphy data from 856 participants (≥50 years) in the Dormir Study.
  • Derived objective sleep metrics (duration, efficiency, WASO, SFI) and RAR parameters (amplitude, mesor, acrophase, pseudo-F).
  • Assessed cognitive domains (executive function, attention, memory, language) using composite z-scores and linear regression models adjusted for covariates.

Main Results:

  • Long sleep duration (>8 hours) correlated with poorer executive function and attention.
  • Long wake after sleep onset (WASO; >62.3 minutes) was associated with deficits in executive function, attention, and memory.
  • Participants with mild cognitive impairment (MCI) or dementia exhibited poorer sleep efficiency, longer WASO, higher SFI, and altered RAR parameters compared to cognitively normal individuals.

Conclusions:

  • Long sleep duration and increased WASO are significant predictors of cognitive deficits in executive function and attention.
  • Findings emphasize the need for domain-specific cognitive assessments in sleep and cognitive research.
  • Objective sleep and circadian rhythm measures offer valuable insights into cognitive health in aging.
