Brief summary

DelAgua Health and Development, Manna Energy and the Rwanda Ministry of Health are collaborating on a project financed by carbon credits that will distribute household-based water filters and high-efficiency cook stoves to approximately 600,000 households in Rwanda. Prior to the full roll out of the campaign, the implementers are conducting research in connection with a distribution among 2000 households in western Rwanda. The objective of this matched cohort study (Phase 1B)are to investigate whether the filters and stoves delivered in October 2012 are still performing and in use, to determine whether they are associated with reductions in exposure to pathogens from drinking water and stoves, and to assembly information on health and other conditions necessary for the design of a large scale health impact evaluation.

Inclusion criteria

Households will be eligible to participate in the study if they reside in selected villages and are willing to participate after receiving complete details regarding the study. Intervention households must have a functioning stove and water filter in order to participate, though they do not need to be in regular use. We will enroll all households with a child under 5 years of age if they are in Ubudehe groups 1 or 2.

Design outcomes

Primary

Measure	Time frame	Description
Personal exposure to PM2.5 and CO (mg/m3)	10 months	PM2.5 and CO concentrations will be measure in mg/m3 and reported as the mean concentration over 48 hours.

Secondary

Measure	Time frame	Description
Thermotolerant coliforms (TTC) in colony forming units (CFU) per 100ml of sample water	10 months	TTC will be measured as the total number of colony forming units (CFU) of TTC in the water sample and will be reported as number of CFU per 100ml of sample water.

Other

Measure	Time frame	Description
Blood pressure	10 months	—
Blood pressure covariates	10 months	—
Use of filter and stove	10 months	—
Exposure to PM2.5 and CO in primary cooking areas (mg/m3)	10 months	PM2.5 and CO concentrations during the 48 hour sampling period
