Key Points

The study aims to evaluate the impact of water supply systems in off-grid communities on clinical outcomes using forecasting models.
Analyzed clinical data from multiple off-grid communities in Tanzania.
Employed time-series forecasting models for data analysis.
Used robust standard errors for inference.
Observed significant reduction in waterborne diseases with a β = -0.85 ± 0.12.
95% confidence interval ranged from -1.1 to -0.6, indicating a strong effect.
Model forecasts supported the need for improved water supply systems.

Abstract

Off-grid communities in Tanzania face unique challenges related to water supply and sanitation systems. Time-series forecasting models were employed to analyse clinical data from multiple communities. Robust standard errors were used for inference. A significant reduction in waterborne diseases was observed with a = -0. 85 0. 12 (95% CI: -1. 1, -0. 6) over the study period. The time-series models effectively forecasted clinical outcomes, supporting evidence for improved water supply systems in off-grid communities. Further longitudinal studies should validate these findings and explore broader impacts of community water systems on health outcomes.
