Chapter 1: Introduction

Background

HIV, a lentivirus that targets CD4 cells, remains a global health crisis. In 2021, UNAIDS reported 1.5 million new infections worldwide, with Africa bearing the highest burden. Uganda alone has over 1.5 million people living with HIV.

Aerobic exercise has demonstrated benefits for chronic illnesses, including mitigating ART side effects (e.g., lipodystrophy, metabolic disorders) and improving mental health (O’Brien et al., 2016). However, Uganda lacks specific guidelines on exercise type, intensity, and duration for HIV patients.

Problem Statement

Despite ART’s success, advanced HIV illnesses persist due to poor clinical outcomes, exacerbated by sedentary lifestyles and ART-related complications (Tugume et al., 2023). Aerobic exercise may reduce treatment costs, prolong asymptomatic phases, and improve well-being (Bopp et al., 2003). Yet, misconceptions—such as exercise worsening HIV—hinder adoption (Frantz & Murenzi, 2013).

Objectives

1. Assess the effect of aerobic exercise on CD4 counts in HIV-positive clients at GMH-Bombo.
2. Evaluate its impact on functional work capacity.
3. Determine its effects on psychological markers (anxiety, depression).

Chapter 2: Literature Review

ART and Exercise Synergy

While ART improves survival, side effects like fatigue and depression persist. Aerobic exercise counters these by:

• Boosting immunity: Increased CD4 counts (Maduagwu et al., 2015).
• Enhancing functional capacity: Improved VO₂max (Scribbans et al., 2016).
• Reducing psychological distress: Lower anxiety/depression (Jayakody et al., 2014).

Gaps: Few studies focus on Uganda, and optimal exercise protocols remain unclear.

Chapter 3: Methodology

Design & Participants

• Quasi-experimental design at GMH-Bombo.
• Inclusion: Asymptomatic adults on ART for ≥12 months.
• Exclusion: Opportunistic infections, age <20.
• Sample: 135 participants (99 after attrition).

Intervention

• Exercise group: 12 weeks of moderate-intensity aerobic exercise (brisk walking, cycling).
• Assessments:
  • CD4 counts (PIMA analyzer).
  • Functional capacity (Duke Activity Status Index).
  • Psychological markers (validated questionnaires).

Analysis

• SPSS v20: Two-sample t-tests (p ≤ 0.05).

Chapter 4: Results

Key Findings

1. Immunological Measures:
   • Exercise group: ↑ CD4 counts (p < 0.001).
   • Control group: Slight decline.
2. Functional Capacity:
   • Exercise group: ↓ perceived exertion, improved VO₂max.
3. Psychological Markers:
   • 58.5% reduction in depression symptoms.
   • Significant anxiety reduction (p = 0.002).

Chapter 5: Conclusions & Recommendations

Conclusions

• Supervised aerobic exercise improves CD4 counts, functional capacity, and mental health.
• Structured programs mitigate ART side effects and enhance quality of life.

Recommendations

• Policy: Integrate exercise into Uganda’s HIV guidelines.
• Clinical Training: Train clinicians in exercise prescription.
• Research: Explore effects on viral load and body composition.
