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...

Area of Science:

  • Neuroscience
  • Public Health
  • Gerontology

Background:

  • Limited research exists on Alzheimer's disease (AD) risk factors in underserved populations, particularly in Africa, due to a focus on Western samples.
  • This neglect has resulted in a scarcity of longitudinal studies investigating dementia and AD within African communities.

Purpose of the Study:

  • To examine the effects of social factors, clinical health, and sex on AD development and cognitive domains in African Americans and Indigenous Africans.
  • To investigate the influence of social engagement, comorbidities, and sex on AD risk and cognitive function across diverse African ancestry populations.

Main Methods:

  • Utilized data from the Indianapolis-Ibadan Dementia Project, a cross-national longitudinal study.
  • Analyzed cognitive, clinical health, and dementia risk data from 3,982 African Americans and 4,353 Indigenous Africans.
  • Examined the impact of social factors, comorbidities, and sex on AD development and cognitive domains (semantic memory, episodic memory, executive functioning).

Main Results:

  • Anticipated that higher social engagement correlates with lower odds of AD diagnosis and higher cognitive scores in both cohorts.
  • Evaluated the predictive impact of comorbidities on AD risk and cognitive decline.
  • Proposed that relationships between risk factors and AD are modified by sex, potentially being stronger for females.

Conclusions:

  • Findings enhance cross-cultural understanding of AD risk factors in diverse populations of African ancestry.
  • Provides a framework for culturally informed interventions and treatments for Alzheimer's disease.
  • Emphasizes the importance of considering cultural, health, and social determinants in AD research and care.
