Multivariable relationships between flooding in neighborhood, rainfall, and enteric pathogens detected in stool collected from children in SaniPath households, 2010-2014a
| a) Flooding of neighborhood and household infrastructure | Enteric infection Adjusted ORa (95% CI) |
| Reported drain flooding | 0.97 (0.66, 1.42) |
| Monthly total rainfall (cm) | 0.98 (0.95, 1.00) |
| Reported drain flooding x Monthly total rainfall (cm) | 1.04 (1.00, 1.07)† |
| Cluster of reported drain flooding | 0.72 (0.46, 1.11) |
| Monthly total rainfall (cm) | 0.99 (0.97, 1.01) |
| Cluster of reported drain flooding x Monthly total rainfall (cm) | 1.05 (1.01, 1.09)† |
| Reported house flooding | 1.02 (0.73, 1.43) |
| Monthly total rainfall (cm) | 1.00 (0.98, 1.02) |
| Reported house flooding x Monthly total rainfall (cm) | NS |
| Cluster of reported house flooding | 1.05 (0.60, 1.83) |
| Monthly total rainfall (cm) | 1.00 (0.98, 1.02) |
| Cluster of reported house flooding x Monthly total rainfall (cm) | NS |
| b) Reported contact | |
| Any reported contact with drain water | 1.36 (0.88, 2.08) |
| Monthly total rainfall (cm) | 1.00 (0.98, 1.02) |
| Any reported contact x Monthly total rainfall (cm) | NS |
| High (>10x/month) reported contact with drain water | 1.28 (0.68, 2.38) |
| Monthly total rainfall (cm) | 0.98 (0.94, 1.01) |
| High reported contact x Monthly total rainfall (cm) | NS |
| Any reported contact with flood water | 1.42 (1.00, 2.01) |
| Monthly total rainfall (cm) | 1.00 (0.98, 1.02) |
| Any reported contact x Monthly total rainfall (cm) | NS |
| High (>10x/month) reported contact with flood water | 1.28 (0.80, 2.06) |
| Monthly total rainfall (cm) | 1.02 (0.99, 1.05) |
| High reported contact x Monthly total rainfall (cm) | NS |
aIn addition to covariates shown, all models were adjusted for type of stool collected, monthly average temperature, presence/absence of household sanitation, household asset index, household income, and mother’s education. Model ORs for all covariates are available in the Supplementary Material. “NS” indicates interaction of rainfall and main effect was not significant at 0.05 and thus not included in model; †p < 0.05
