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...

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...

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.

Ultraprocessed food (UPF) consumption is high in Brazilian elderly with cognitive impairment. Higher UPF intake correlates with poorer physical performance, indicating a need for dietary interventions in this population.

Area of Science:

  • Gerontology
  • Nutritional Science
  • Cognitive Health

Background:

  • Ultraprocessed foods (UPFs) are linked to cognitive decline, with significant consumption in Brazil.
  • Limited research exists on UPF intake among elderly individuals experiencing cognitive impairment.

Purpose of the Study:

  • To quantify UPF consumption in cognitively impaired elderly individuals.
  • To identify key UPF sources contributing to intake.
  • To examine associations between UPF consumption and anthropometric/body composition parameters, including sarcopenia.

Main Methods:

  • Cross-sectional study of elderly participants diagnosed with mild cognitive impairment or dementia.
  • Assessment of anthropometry, body composition, handgrip strength, and physical performance (Timed Up and Go test).
  • Evaluation of total UPF consumption via food frequency questionnaire, analyzed in tertiles.

Main Results:

  • High median daily UPF consumption (129.9g) was observed in 75 elderly participants (mean age 77.6).
  • Mayonnaise, frozen potatoes, ice cream, and sugary beverages were primary UPF contributors.
  • No significant association found between UPF intake and anthropometry, body composition, or handgrip strength.
  • Worse physical performance (longer TUG test times) was linked to the highest UPF consumption tertile (p=0.03).

Conclusions:

  • Elderly individuals with cognitive impairment exhibit high UPF consumption.
  • Specific UPFs like mayonnaise, frozen potatoes, and sugary drinks are major contributors.
  • Elevated UPF intake is associated with diminished physical performance in this demographic.
