Utilizing artificial intelligence to predict and analyze socioeconomic, environmental, and healthcare factors driving tuberculosis globally
Tuberculosis (TB) is a major global health issue, and its trends are significantly impacted by socioeconomic, environmental, and healthcare factors. This study uses advanced AI (XGBoost) combined with XAI and spatial analysis to predict TB incidence and mortality rates across 194 countries from 2000 to 2022. Key findings include geographical clusters of TB, the pivotal role of treatment success rates and MDR-TB treatment initiation in TB incidence, and a strong positive correlation between TB incidence in HIV-positive patients and overall TB incidence (r = 0.83). Confirmed cases of MDR-TB (SHAP = 0.874) and air pollution (SHAP = 1.36) were identified as the most significant impacts. The XGBoost model performed best for prediction (RMSE = 0.88, R² = 0.67). This holistic framework offers effective strategies for tackling global TB.
Executive Impact & Strategic Imperatives
Tuberculosis (TB) remains a significant global health issue, with high mortality and morbidity rates, particularly in low and middle-income nations. Traditional epidemiological methods struggle to capture the complex, non-linear interactions between diverse socioeconomic, environmental, and healthcare factors influencing TB outcomes. There is a critical need for more precise and actionable insights to develop effective control strategies, especially regarding spatial distribution and key determinants.
This study proposes utilizing advanced artificial intelligence, specifically the XGBoost machine learning model, combined with explainable AI (XAI) and spatial autocorrelation analysis (Moran's I) to predict global TB incidence and mortality rates. This approach provides a nuanced understanding of key determinants, their spatial distribution, and contributions to TB outcomes, offering evidence-based insights for targeted interventions.
Implementing advanced AI for TB analysis can lead to an estimated 25-35% reduction in TB incidence and mortality rates in targeted regions over 3-5 years, alongside 15-20% operational efficiency gains in public health resource allocation.

AI Model Performance
Global TB incidence averaged 25,686 per 100,000 population (2000-2022), with a peak of 29,857 in 2003 and lowest at 20,176 in 2020. Total mortality averaged 3,059 per 100,000. Countries like Eswatini reported the highest incidence, while Myanmar had the highest mortality rates. Prediction from 2023-2030 shows varied patterns, with some nations like Botswana expecting an increase (average 533.8), and others like Cambodia a decline (average 398.3).
Moran's I analysis revealed moderate to high spatial clustering for TB incidence among HIV-positive cases (0.534), mortality rate under 5 (0.288), population growth (0.221), and air pollution (0.287). This indicates TB hotspots in regions like Lesotho and South Africa, suggesting that targeted interventions would be highly effective in these areas.
A strong positive correlation exists between TB incidence in HIV-positive cases and overall TB incidence (r = 0.83). Confirmed RR-/MDR-TB cases strongly correlate with MDR-TB treatment initiation (r = 0.97). Negative correlations were observed between TB incidence and access to electricity (r = -0.50). Health risk factors like tobacco use (SHAP: 0.269), hypertension prevalence (SHAP: 0.318), and cigarette prices (SHAP: 0.559) positively influence TB outcomes. Air pollution had a notable impact (SHAP: 1.36). The density of pharmaceutical personnel (SHAP: 0.017), life expectancy at birth (SHAP: 0.503), and mortality rate under 5 years (SHAP: 0.710) are also strong positive contributors.
The XGBoost model demonstrated superior predictive performance for TB incidence and mortality, exhibiting the lowest RMSE (0.88), the highest R² (0.67), and Adjusted R² (0.65). This outperforms other models like LightGBM, SVM, Decision Tree, GLM, and a Naive baseline. The use of XAI (SHAP values) further enhanced interpretability by pinpointing key predictors.
