Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Behavior Modification

Behavioral approaches have often been criticized for ignoring mental processes and focusing solely on observable behavior. However, these approaches provide an optimistic perspective for individuals seeking to change their behaviors. Rather than concentrating on intrinsic personality traits, behavioral approaches suggest that even longstanding habits can be modified by changing the reward contingencies that maintain them.
A real-world application of operant conditioning principles is applied...

Models of Health Promotion and Illness Prevention II

2.2K
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...

Area of Science:

  • Pediatric Health
  • Public Health Interventions
  • School-Based Health Programs

Background:

  • Childhood obesity and cardiovascular health are significant public health concerns.
  • School-based health programs play a crucial role in promoting healthy lifestyles among children.
  • Existing programs often focus on educational lessons, with less emphasis on environmental modifications.

Purpose of the Study:

  • To evaluate the effectiveness of environmental activities integrated into a school-based health program.
  • To compare the impact of educational lessons alone versus combined educational and environmental interventions on 6th graders' health behaviors.
  • To assess changes in diet, physical activity, and sedentary behaviors.

Main Methods:

  • A quasi-experimental design involving 2315 sixth-grade students in the Project Healthy Schools program.
  • Comparison of baseline and follow-up health questionnaire data between two groups: educational lessons only, and educational lessons plus environmental activities.
  • Statistical analysis included descriptive statistics and one-way ANOVA to compare outcomes.

Main Results:

  • Students in schools with environmental activities reported higher fruit intake (p = .046) and moderate physical activity (p = .009).
  • Significant reductions were observed in sugary beverage consumption (p = .054) and fatty/sugary food servings (p = .002) in the combined intervention group.
  • No significant decrease in TV viewing time was found, and mobile device usage increased in both groups.

Conclusions:

  • School-based health programs incorporating environmental activities alongside educational lessons demonstrate superior effectiveness in improving children's diet and physical activity.
  • Environmental modifications within schools can enhance the impact of health education, leading to better health outcomes in middle school students.
  • Future interventions should consider comprehensive environmental strategies to combat childhood obesity and promote cardiovascular health.
