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

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...

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.

Nearly 60% of dementia cases in Brazil are preventable by addressing 14 modifiable risk factors. Targeting factors like education and vision loss can significantly reduce dementia risk, especially for women.

Area of Science:

  • Neurology
  • Public Health
  • Epidemiology

Background:

  • The 2024 Lancet Commission identified 14 modifiable dementia risk factors.
  • Low- and middle-income countries (LMICs) present a significant opportunity for dementia prevention due to higher risk factor prevalence.

Purpose of the Study:

  • To determine the potential for dementia prevention in Brazil attributable to 14 modifiable risk factors.
  • To provide the first LMIC-specific figure for dementia prevention potential in Brazil.

Main Methods:

  • Analysis of data from 9,949 participants aged 50+ from the ELSI-Brazil study (2019-2021).
  • Estimation of modifiable risk factor prevalence and calculation of population attributable fractions (PAF) using Lancet Commission relative risks.
  • Principal component analysis to account for factor communalities and stratified analyses by sex, race, and region.

Main Results:

  • The overall PAF for the 14 modifiable risk factors was 59.5%.
  • Key contributors included less education (9.5%), untreated visual loss (9.2%), and midlife depression (6.3%).
  • Dementia risk reduction potential was higher in women (61.1%) than men (58.2%), with similar PAFs across race and region.

Conclusions:

  • Addressing 14 modifiable risk factors could prevent almost 60% of dementia cases in Brazil.
  • Tailored, sex-specific public health strategies are recommended to mitigate Brazil's dementia burden.
