Models of Health Promotion and Illness Prevention I01:25

Models of Health Promotion and Illness Prevention I

2.6K
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...

Models 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.
The agent-host-environment model states that disease results...

Community Based Intervention

232
Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Assessment of the Gastrointestinal System II: Health Perception Pattern

393
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

Regulation of Food Intake01:30

Regulation of Food Intake

2.2K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

599
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Area of Science:

  • Nutrition Science
  • Public Health
  • Pediatric Health

Background:

  • Childhood fruit and vegetable consumption is low in the U.S., impacting chronic disease prevention.
  • Elementary school children often have insufficient intake of essential fruits and vegetables.
  • Developing effective interventions for school settings is crucial for public health.

Purpose of the Study:

  • To pilot a role modeling intervention to boost fruit and vegetable intake in elementary school cafeterias.
  • To assess the impact of role modeling on children's consumption of fruits and vegetables.
  • To evaluate the acceptability of a school-based role modeling intervention.

Main Methods:

  • A one-year, repeated cross-sectional study using digital photography to measure fruit and vegetable waste.
  • Assessed waste from 566 trays at baseline and 231 trays at follow-up among K-5 students.
  • Utilized Mann-Whitney tests for statistical analysis and qualitative feedback for acceptability.

Main Results:

  • Significant increase in students consuming all selected fruits (11.1%) and vegetables (8.7%).
  • Reduced the proportion of students not eating any fruit by 16.0%.
  • Positive feedback on intervention acceptance from staff and students.

Conclusions:

  • Role modeling in school cafeterias shows promise for promoting healthy eating habits.
  • This strategy may contribute to chronic disease prevention in children.
  • Further large-scale research is needed to confirm efficacy and acceptability.
