Background of the Study
Tuberculosis (TB) remains a major public health concern in Nigeria, ranking among the top 10 causes of mortality and morbidity in the country (WHO, 2024). Kano State, located in northern Nigeria, has one of the highest TB prevalence rates due to factors such as poverty, overcrowding, poor healthcare access, and limited diagnostic capacity (Adebayo & Yusuf, 2023). Despite national efforts, TB control remains challenging due to delayed case detection, inadequate treatment adherence, and high transmission rates.
The application of statistical models in epidemiology has become crucial in predicting disease prevalence and informing public health interventions. Traditional statistical approaches, such as regression analysis, time series forecasting, and Bayesian models, have been widely used to predict TB trends (Adepoju et al., 2024). More advanced machine learning techniques, including neural networks and decision trees, are also being explored to enhance predictive accuracy (Bello & Olatunji, 2024).
This study aims to examine various statistical models used in predicting TB prevalence in Kano State, evaluating their accuracy and effectiveness in forecasting TB trends. The findings will support policymakers and public health officials in strengthening TB control strategies and resource allocation.
Statement of the Problem
The rising TB burden in Kano State underscores the need for more efficient predictive models to aid in disease surveillance and control. Current TB monitoring relies heavily on passive case detection, which often underestimates true prevalence due to poor health-seeking behavior and diagnostic gaps (Adebayo & Yusuf, 2023).
Although various statistical models have been applied to TB prevalence prediction, gaps remain in their accuracy, data quality, and practical implementation. Traditional models, such as linear regression and time series analysis, may not fully capture complex TB transmission dynamics (Adepoju et al., 2024). Machine learning-based models offer potential improvements but require large, high-quality datasets for training.
This study seeks to evaluate the strengths and limitations of statistical models in predicting TB prevalence in Kano State, with a view to improving surveillance and intervention planning.
Objectives of the Study
1. To identify statistical models commonly used in predicting TB prevalence in Kano State.
2. To evaluate the accuracy and reliability of different predictive models.
3. To recommend an optimal statistical approach for TB prevalence forecasting in Kano State.
Research Questions
1. What statistical models are commonly used to predict TB prevalence in Kano State?
2. How do different predictive models compare in terms of accuracy and reliability?
3. What is the most suitable statistical approach for forecasting TB prevalence in Kano State?
Research Hypotheses
1. Traditional regression-based models have lower predictive accuracy than machine learning models in forecasting TB prevalence.
2. Data quality and availability significantly impact the accuracy of TB predictive models.
3. The integration of multiple statistical approaches improves TB prevalence forecasting in Kano State.
Scope and Limitations of the Study
This study will focus on the statistical models used in predicting TB prevalence in Kano State. It will analyze hospital records, national TB surveillance data, and public health reports. The study will compare traditional and machine-learning-based predictive models.
Limitations may include incomplete TB case data, inconsistencies in diagnostic records, and computational challenges associated with complex modeling techniques.
