An interventional study of SODIS Bottle in Dysentery and Diarrhoea, sponsored by Royal College of Surgeons, Ireland. Completed at 3 sites in 3 countries. Open to participants aged 12 Months to 5 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2011-11-10.

SODISWATER was a health impact assessment study investigating the effect of sunlight to inactivate microbial pathogens in drinking water. This study was carried out by observing whether children younger than 5 years old who drink solar disinfected water were healthier than those who did not. Health was measured by how often the children had diarrhoea or dysentery.
Caregivers for the participants were given plastic bottles to place in the sun, water samples were then collected from these plastic bottles to be analyzed. They were also requested to fill in diarrhea diaries.
TESTABLE RESEARCH HYPOTHESES:
Health Impact Assessment: Children who use solar disinfected water will have:
(a) lower morbidity due to non-bloody diarrhoea and bloody diarrhoea (c) increased growth rates (d) lower mortality (e) increased family productivity (f) decreased care-giver burden (g) increased school attendance
The current evidence base for solar disinfection in the prevention of diarrhoeal disease in children rests on three published studies. All share two significant weaknesses: all were carried out in Kenya, in communities which have very high incidences of diarrhoeal disease and water characterised by high levels of both turbidity and microbial contamination. Furthermore, neither of the studies of diarrhoeal disease distinguished between dysentery (associated with significant risk of mortality) and other sorts of diarrhoea, which carry a far lower risk. The present study will extend the evidence base into communities at lower risk and with higher water quality. Furthermore, by using pictorial diaries, dysentery can be analysed as a specific health endpoint. Diarrhoea will be recorded consistent with the World Health organisation definition: three or more loose or watery stools in a 24-hour period and/or stools containing blood or mucus.
AIM OF THE PROJECT IN RELATION TO HEALTH IMPACT ASSESSMENT STUDIES:
The primary aim of the SODISWATER PROJECT is to demonstrate that SODIS is an appropriate intervention against diarrhoeal and waterborne disease among communities in developing countries and those affected by natural or man-made disasters by conducting multi-centred epidemiologically controlled Health Impact Assessments of the SODIS technique across the African Continent under a variety of social, geographical and climactic conditions.
SCIENTIFIC OBJECTIVES OF SODISWATER IN RELATION TO HEALTH IMPACT ASSESSMENT STUDIES:
64 studies on the registry are indexed under Dysentery; 9 are open to participants now.
This study's enrollment of 2,400 is above the median of 145 across 51 interventional studies indexed under Dysentery.

Exclusion Criteria:
Caregivers in the intervention group were given two 2-litre plastic bottles. Bottle was filled with available water and placed in direct sunlight for a minimum of 6 hours. Water was consumed the next day while second bottle was being consumed.
Other: SODIS Bottle
Caregivers in this group were asked to maintain their usual practices regarding drinking water so that disease rates could be compared with the SODIS arm
Other: SODIS Bottle
SODIS Bottles used by SODIS group to treat their drinking water
Also known as: Unused 2-litre PET bottles (e.g. Coca-Cola, Pepsi)
Dysentery disease rate
Incidence of occurrence of blood or mucous in diarrhoeal stools was noted by caregivers and recorded in a pictorial diary which was collected every 2 weeks.
Time frame: 12 month
Diarrhoea disease rate
Incidence of diarrhoea and numbers of diarrhoeal episodes was noted by caregivers and recorded in a pictorial diary which was collected every 2 weeks.
Time frame: 12 months
Height and weight benefit
Anthropometric measurements of height and weight were recorded at 3 month intervals across the 12 month study period.
Time frame: 12 months
