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...

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:

  • Cognitive neuroscience
  • Gerontology
  • Socioeconomic determinants of health

Background:

  • Economic hardship in Brazil often leads to early workforce entry before age 16.
  • The impact of early employment on formal education is known, but its effect on late-life cognition is less clear.
  • Early employment might offer cognitive stimulation, potentially benefiting cognitive function in later life.

Purpose of the Study:

  • To investigate the association between the age of first employment and cognitive function in later life.
  • To analyze cognitive performance in temporal orientation, memory, and verbal fluency based on early work initiation.
  • To understand the relationship between early labor force participation and cognitive aging in a Brazilian national cohort.

Main Methods:

  • Utilized data from the Brazilian Longitudinal Study of Aging (ELSI-Br).
  • Assessed temporal orientation, memory, and verbal fluency, standardizing memory and fluency scores by age and sex.
  • Employed linear regression models, categorizing age at work initiation (≤10, 11-15, ≥16 years) and adjusting for demographic and socioeconomic factors.

Main Results:

  • A significant portion of participants (41.74%) began working at or before age 10.
  • Individuals starting work at ages 11-15 and ≥16 showed higher orientation and memory scores compared to those starting at ≤10 years.
  • Verbal fluency showed a trend towards improvement for those starting work after age 16.

Conclusions:

  • Early workforce entry is associated with cognitive function in late life.
  • Findings suggest that delaying employment may be beneficial for cognitive health in older Brazilians.
  • Results can inform policies aimed at promoting education and delaying employment among vulnerable populations.
