Thesis Abstract

Abstract
 

Childhood obesity has become a global public health challenge with profound implications for physical and mental well-being. School-based physical activity programs have emerged as a promising approach to combat this issue, offering structured opportunities for children to engage in regular exercise and adopt healthy habits. This longitudinal study aims to evaluate the effectiveness of such programs in reducing childhood obesity rates over an extended period. The research will employ a mixed-methods design, combining quantitative measurements of body mass index (BMI) and physical activity levels with qualitative insights from students, teachers, and parents. By conducting a comprehensive assessment of the programs' impact, this study seeks to inform evidence-based strategies for promoting healthy lifestyles and mitigating the risks associated with childhood obesity. The findings will contribute to the development of tailored interventions and policies that support the holistic well-being of children within the school environment.

Thesis Overview

Chapter 1: Introduction

1.1 Background 

Childhood obesity has emerged as a pressing public health concern in recent decades, with alarming rates observed across various regions and socioeconomic groups. Excessive weight gain during childhood can lead to a range of physical and psychological complications, including cardiovascular diseases, type 2 diabetes, orthopedic problems, and diminished self-esteem. Addressing this issue requires a multifaceted approach that targets various contributing factors, such as sedentary lifestyles, unhealthy dietary habits, and environmental influences.

1.2 Problem Statement 

Despite increased awareness and efforts to tackle childhood obesity, its prevalence remains a significant challenge. Traditional interventions have often focused on individual behavior modification, which may not be sufficient to address the complex interplay of factors contributing to this issue. School-based physical activity programs present a promising avenue for promoting healthier lifestyles among children, leveraging the educational environment and peer influences to foster positive changes.

1.3 Research Objectives 

The primary objective of this study is to evaluate the long-term impact of school-based physical activity programs on childhood obesity rates. Specifically, the research aims to:

1. Assess changes in body mass index (BMI) and obesity prevalence among participating students over an extended period.
2. Examine the influence of the programs on students' physical activity levels and sedentary behaviors.
3. Explore the perceptions and experiences of students, teachers, and parents regarding the implementation and effectiveness of the programs.
4. Identify potential barriers and facilitators to the successful implementation of school-based physical activity interventions.

1.4 Research Questions 

The study will address the following research questions:

1. How do childhood obesity rates change over time among students participating in school-based physical activity programs compared to those in a control group?
2. What is the effect of these programs on students' physical activity levels and sedentary behaviors?
3. How do students, teachers, and parents perceive the impact and effectiveness of the programs?
4. What factors facilitate or hinder the successful implementation and sustainability of school-based physical activity interventions?

1.5 Significance of the Study 

This research holds significant implications for addressing the pressing issue of childhood obesity. By evaluating the long-term impact of school-based physical activity programs, the study will contribute valuable insights to inform evidence-based strategies and policies. The findings may guide the development and implementation of effective interventions tailored to the unique needs and contexts of diverse school communities.

1.6 Scope and Limitations 

The study will focus on elementary and middle school students within a specific geographic region. While the findings may have broader relevance, it is essential to consider potential limitations, such as variations in school environments, resources, and community characteristics, which may influence the generalizability of the results.

1.7 Definition of Key Terms

• Childhood obesity: Defined as a body mass index (BMI) at or above the 95th percentile for children and teens of the same age and sex.
• School-based physical activity programs: Structured initiatives implemented within the school setting to promote physical activity and healthy lifestyles among students.
• Body mass index (BMI): A measure calculated using a person's weight and height to assess body weight status.
• Sedentary behavior: Activities involving minimal physical movement and low levels of energy expenditure, such as prolonged sitting or screen time.
