We investigated the relationship between distance to improved water sources and hygiene practices Karamoja Uganda. We conducted semi‐structured interviews and household observations among mothers of children under 24 months (n=56) from seven villages during the rainy season, when seasonal stream use is common. Distance to water source was estimated using a GPS monitor and total water use was estimated per‐capita by the volume of water containers used divided by the total household members. Households with a water source closer than 300 meters had significantly greater daily hand washing frequency among mothers (4.6 vs 3.6, p=.038) but not among children (3.00 versus 2.89, p=0.33). When the closest water source was a borehole compared to a stream, the daily frequency of hand washing was higher among children (3.4 vs 2.8 times, p .023) but not among mothers (4.2 vs 4.8, p=0.60). The mean per capita water use was 10.9L (SE 1.1), and 82.1% of households consumed less than 20L per person. Larger households did not account for greater water needs: households with more than 5 children had the same total water usage as households with fewer than 5 children (64.8L vs 64.1L, p=0.53). Findings suggest that children in large families may be vulnerable to poor hygiene practices owing to a lack of sufficient water for increased family size. Increasing access to boreholes may improve child hand‐washing frequency in this remote region.
