      DelAgua Health Rwanda (Implementation) Ltd. together with Rwanda Ministry of Health (MoH) are&#xD;
      delivering an intervention, consisting on the free distribution of one advance water filter&#xD;
      and one improved cookstove to all household classified as ubudehe 1 and 2 according to&#xD;
      government approved registers (poorest tertile), in Western Province. The aim of this&#xD;
      intervention is to reduce the morbidity and mortality associated with diarrhoeal diseases and&#xD;
      pneumonia in Rwanda.&#xD;
&#xD;
      The London School of Hygiene and Tropical Medicine (LSHTM) will be undertaking an independent&#xD;
      evaluation of this large-scale intervention to assess its impact on health. The trial will&#xD;
      evaluate whether the provision of improved cookstoves and advance water filters can reduce&#xD;
      pneumonia and diarrhoea disease in children under 5 years of age.&#xD;
&#xD;
      A cluster randomized controlled trial (CRCT) with two arms of unequal size (3:1 ratio) will&#xD;
      be use to answer this question. The 96 sectors in Western Province, Rwanda, will be&#xD;
      randomised to either receive the intervention or the control. Each eligible household in&#xD;
      intervention sectors will receive one EcoZoom™ Spartan and one Vestergaard Frandsen Lifestraw&#xD;
      Family™ 2.1 water filter free of charge. Eligible households in control sectors will continue&#xD;
      with their traditional cooking and drinking practices. Health data on children under 5 years&#xD;
      of age will be collected from community health worker (CHW) and health facility records all&#xD;
      across Western Province to evaluate the health impact of the intervention. The study will&#xD;
      encompass 12 months of follow-up. After this time the control sectors will receive the&#xD;
      intervention.&#xD;
&#xD;
      This independent evaluation will also include a nested village-level study within the larger&#xD;
      sector-level study, with the aim to evaluate uptake, consistent use and acceptability of the&#xD;
      intervention, as well as to assess the impact on environmental exposures and health outcomes.&#xD;
      174 villages (74 controls and 74 intervention) will be selected for participation. Household&#xD;
      surveys will be used to collect data on intervention use and acceptability as well as on&#xD;
      self-reported health data. Water samples will be collected and monitoring of exposure to&#xD;
      Households Air Pollution (HAP) will be undertaken. Measurements of blood pressure, expirated&#xD;
      Carbon monoxide (CO) and pulse CO-oximetry will be undertake in primary cooks and or children&#xD;
      under 5 years of age. Additionally, as part of this nested study, two exploratory studies&#xD;
      will also be conducted. One will be focused on assessing the potential of biomarkers as&#xD;
      indicators of environmental exposures (mainly HAP and water quality) and health status, while&#xD;
      the other exploratory sub-study will assess the reactivity of participants to the use of&#xD;
      remotely reporting electronic sensors to measure target behaviours.&#xD;

    <description>The Vestergaard Frandsen Lifestraw Family™ 2.1 is a point-of-use water treatment system.Water is poured through a 20 micron pre-filter into a 6L influent water tank.This water then filters through a 0.20 micron hollow-fiber ultrafiltration membrane into a 5.5L storage container.Water is then poured through a plastic tap, which prevents re-contamination.This system filters up to 18,000L of water.The system exceeds the WHO's &quot;highly protective&quot; standard for household water treatment technologies.The EcoZoom™ Spartan stove concentrates the combustion process while channeling airflow to completely burn the fuel provided.The stove has a ceramic combustion chamber within a steel housing, which is topped with a cast iron stove.The stove includes a rack for placing firewood and a pot skirt that improves the thermal efficiency.The cookstoves and filters will be delivered together at no cost to participating households.Households will receive instructions on how to operate these devices.</description>

      <textblock>
        Inclusion Criteria:&#xD;
&#xD;

&#xD;
          -  All households shown on updated 2012 government registers to be members of ubudehe 1&#xD;
             and 2 in Western Province, Rwanda will be eligible to participate in the study.&#xD;
&#xD;
          -  For nested village-level study:&#xD;
&#xD;
          -  All villages from all sectors in Western province, according to official Government&#xD;
             lists will be eligible for participation with the exception of those villages that&#xD;

&#xD;
          -  At the village-level, all households that are classified as ubudehe 1 &amp; 2 according to&#xD;
             updated 2012 government registers, are part of the village, are able to provide&#xD;
             informed consent, and that have at least one child under 4 years of age at the time of&#xD;
             enrollment will be eligible for participation. Presence of a child under 4 years of&#xD;
             age will be assessed by checking dates of birth or recorded age in months in the CHW&#xD;
             register of children &lt;5 years (Igitabo Cy'Ibikorwa Byo Gukurikirana), which are&#xD;
             maintained at the village by CHW (though occasionally these are transferred to health&#xD;
             centers). If this data is missing will be assesses based on CHW's report. In those&#xD;
             cases where a village has more than the required number of participating households&#xD;
             (10 household), a random selection of 10 households will be drawn.&#xD;
&#xD;
          -  For the assessment of personal exposure to HAP a stricter set of eligibility criteria&#xD;
             will be applied. Households that comply with the following eligibility criteria will&#xD;
             be eligible for the exposure to HAP sub-study.&#xD;
&#xD;
               -  Have a child 1.5-4 year old,&#xD;
&#xD;
               -  Have a child healthy enough to wear the monitoring equipment (as perceived by the&#xD;
                  mother),&#xD;
&#xD;
               -  Have a non-smoking primary cook,&#xD;
&#xD;
               -  Have a primary cook that is currently not pregnant (as far as she is aware of),&#xD;
                  and&#xD;
&#xD;
               -  Have a primary cook that is in a healthy state to wear the monitoring equipment&#xD;
&#xD;
          -  The first two households identified from a randomised list will be invited to&#xD;
             participate.&#xD;
&#xD;
          -  For the biomarker sub-studies, both the primary cook and the child under 4 years of&#xD;
             age from households undergoing HAP exposure assessment will be eligible for the&#xD;
             inflammatory cytokine biomarker study. For the enteric seroconversion study, all&#xD;
             children aged 6 to 12 months will be eligible for participation.&#xD;

intervention name: Water filter and cookstove
description: The Vestergaard Frandsen Lifestraw Family™ 2.1 is a point-of-use water treatment system.Water is poured through a 20 micron pre-filter into a 6L influent water tank.This water then filters through a 0.20 micron hollow-fiber ultrafiltration membrane into a 5.5L storage container.Water is then poured through a plastic tap, which prevents re-contamination.This system filters up to 18,000L of water.The system exceeds the WHO's "highly protective" standard for household water treatment technologies.The EcoZoom™ Spartan stove concentrates the combustion process while channeling airflow to completely burn the fuel provided.The stove has a ceramic combustion chamber within a steel housing, which is topped with a cast iron stove.The stove includes a rack for placing firewood and a pot skirt that improves the thermal efficiency.The cookstoves and filters will be delivered together at no cost to participating households.Households will receive instructions on how to operate these devices.
