TIME SERIES ANALYSIS OF HIV/AIDS AMONG CHILDREN AGED 15 YEARS AND BELOW AND ITS EFFECT ON HEALTH STATUS
CHAPTER ONE
1.0 Introduction
This chapter outlines the background of the study, problem statement, purpose, general and specific objectives, research hypotheses, significance, and scope of the study.
1.1 Background of the Study
Over the past two decades, HIV/AIDS has continued to spread globally, leading to the death of millions of people, particularly adults in their most productive years. This has disrupted families, increased poverty, and left many children orphaned (UNAIDS, 2009). The epidemic significantly affects the workforce and has reversed social and economic progress in many countries, even threatening political stability in some cases.
According to UNAIDS (2009), by the end of 2006, approximately 39.5 million people were living with HIV worldwide, including 2.3 million children under 15 years. Sub-Saharan Africa remains the most affected region, with millions of infections and deaths recorded annually.
In Uganda, despite efforts to combat the disease, about one million people are living with HIV/AIDS (MOH and ORC Macro, 2006). The prevalence rate among adults aged 18–59 years is about 6.7%, with higher rates in urban areas such as Kampala. This high prevalence among the productive population has serious health, social, and economic implications.
The introduction of Antiretroviral Therapy (ART) in 1996 greatly improved the management of HIV/AIDS by reducing mortality and enhancing the quality of life. However, access remains limited in developing countries. Additionally, studies from developed countries show that ART affects body composition, but such data is limited in resource-constrained settings. Therefore, this study aims to analyze HIV/AIDS trends among children aged 15 years and below and their health outcomes.
1.2 Problem Statement
The increased availability of antiretroviral drugs among adults has influenced the nutritional status of people living with HIV/AIDS. HIV infection increases energy requirements and affects nutrition through reduced food intake, poor nutrient absorption, and metabolic changes, often leading to weight loss.
In Uganda, the rising number of HIV/AIDS cases among children under 15 years is alarming despite government interventions. This situation necessitates a detailed analysis of HIV/AIDS trends among children to better understand its impact on their health status.
1.3 Objectives of the Study
1.3.1 General Objective
To analyze trends in HIV/AIDS among children aged 15 years and below and assess their health status.
1.3.2 Specific Objectives
- To determine the distribution of HIV/AIDS among children under 15 years.
- To forecast HIV/AIDS prevalence among children under 15 years in Uganda.
1.4 Research Hypotheses
- H₀₁: There is no significant trend in HIV/AIDS prevalence among children under 15 years.
- H₀₂: There is no seasonal variation in HIV/AIDS prevalence among children.
1.5 Scope of the Study
1.5.1 Content Scope
The study focuses on the distribution of HIV/AIDS among children under 15 years, comparison by region and residence, and forecasting prevalence trends in Uganda.
1.5.2 Time Scope
The study will analyze data from the period 2000 to 2015.
1.6 Significance of the Study
- The study will help researchers understand HIV/AIDS distribution among children.
- It will assist the government in comparing prevalence across regions and residences.
- It will support future forecasting and planning for HIV/AIDS interventions.
CHAPTER TWO: LITERATURE REVIEW
2.0 Introduction
This chapter reviews existing literature related to HIV/AIDS among children.
2.1 Distribution of HIV/AIDS Among Children
HIV/AIDS is a global epidemic caused by the human immunodeficiency virus, which weakens the immune system. Since its discovery in the 1980s, millions of people have died, and many more continue to live with the virus.
The epidemic remains widespread, especially in Sub-Saharan Africa, which carries the highest burden. The disease continues to grow due to new transmission patterns and limited access to healthcare services in developing countries.
Efforts to control HIV/AIDS have included education, awareness, and treatment programs. Studies show that increased knowledge of HIV/AIDS leads to safer behaviors such as delayed sexual activity and condom use.
Children and young people are among the most vulnerable groups, with many infections occurring through mother-to-child transmission. Access to treatment for children remains limited compared to adults, contributing to high mortality rates.
CHAPTER THREE: METHODOLOGY
3.0 Introduction
This chapter explains the methods used in conducting the study, including research design, data sources, processing, and analysis techniques.
3.1 Research Design
The study will adopt a quantitative research approach using structured secondary data obtained from Ministry of Health records.
3.2 Data Sources
Data will be collected from existing records, publications, and reports from the Ministry of Health.
3.3 Data Processing and Analysis
Data will be edited, coded, and analyzed using statistical tools. Descriptive statistics and time series analysis will be used, with results presented in tables and graphs.
3.3.1 Time Series Analysis
The study will analyze trends and seasonal patterns in HIV prevalence using a multiplicative model:
Yt=Tt×StY_t = T_t \times S_t
Where:
- YtY_t = observed data
- TtT_t = trend component
- StS_t = seasonal component
Statistical tests such as the Runs Test and Kruskal-Wallis Test will be used to determine trends and seasonality.
3.3.2 ARIMA Model
The ARIMA (Autoregressive Integrated Moving Average) model will be used for forecasting HIV prevalence. The process involves:
- Model identification (p, d, q)
- Parameter estimation
- Diagnostic checking
- Forecasting
3.4 Ethical Considerations
The study will ensure confidentiality and use data strictly for academic purposes. Relevant authorities will be informed about the purpose of the research.
