Summary
Community health worker (CHW) interventions effectively reduce stunting in low- and middle-income countries (LMICs). Training enhances outcomes, but multisectoral collaboration is vital for maximizing impact.
Area of Science:
- Public Health
- Global Health
- Child Nutrition
Background:
- Child stunting remains a significant public health issue in low- and middle-income countries (LMICs).
- Community health workers (CHWs) are crucial for delivering health interventions in resource-limited settings.
Purpose of the Study:
- To evaluate the effectiveness of interventions delivered by CHWs in reducing child stunting.
- To identify strategies employed by CHWs that contribute to stunting reduction.
Main Methods:
- A systematic review was conducted following PRISMA guidelines.
- Literature search encompassed major electronic databases, reference lists, and grey literature from 2016 to 2023.
- Seventeen articles were included in the final analysis from 2,899 initial results.
Main Results:
- CHW-led interventions demonstrated a significant reduction in stunting rates.
- Training and refresher courses for CHWs were associated with improved intervention outcomes.
- Challenges identified include inconsistent implementation and resource limitations.
Conclusions:
- CHW-led interventions play a significant role in reducing childhood stunting.
- CHWs offer accessible and reliable resources for local communities.
- Multisectoral collaboration is essential to overcome challenges and maximize the impact of CHW programs.

01:26Methods Of Healthcare Delivery System
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 limited...

01:18Models of Health Promotion and Illness Prevention II
The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.

01:25Models of Health Promotion and Illness Prevention I
A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.
The health belief model (HBM) attempts to predict health-related behavior in specific belief patterns. According to the HBM, a person's...

01:30Primary Healthcare Services
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.
