Wood Stove Interventions and Child Respiratory Health
NCT02240134 · View on ClinicalTrials.gov ↗
Study Summary
Acute lower respiratory tract infections (LRTIs) account for more than 27% of all hospitalizations among US children under five years of age, with recurrent LRTIs in children a recognized risk factor for asthma. Residential biomass combustion leads to elevated indoor levels of fine particulate matter (PM2.5) that often exceed current health-based air quality standards. PM2.5 exposure is associated with many adverse health outcomes, including a greater than three-fold increased risk of LRTIs. To date, exposure reduction strategies in wood stove homes have been either inconsistently effective or include factors that limit widespread dissemination and continued compliance in rural and economically disadvantaged populations. In this project, the investigators propose to test the efficacy of two intervention strategies for reducing indoor wood smoke PM2.5 exposures and children's risk of LRTI in three unique and underserved settings: (1) rural mountain valley communities in western Montana; (2) Navajo Nation communities; and (3) Alaska Native Villages. The investigators will conduct a three-arm randomized placebo-controlled post-only intervention trial in wood stove homes with children less than five years old. Education on best-burn practices and training on the use of simple instruments (i.e., stove thermometers and wood moisture meters) will be introduced as one intervention arm (Tx1). This intervention will be evaluated against an indoor air filtration unit arm (Tx2), as well as a placebo arm (Tx3, sham air filters). The primary outcome will be LRTI incidence among children under five years of age. To allow for detection of exposure and outcome differences within each of the three regions, a sample of 324 homes, or 108 within each study area will be equally assigned to each of the three intervention arms. The overall hypothesis is that a low-cost, educational intervention targeting indoor wood smoke PM2.5 exposures will be sustainable, and can reduce children's risk

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT02240134
The ClinicalTrials.gov registry entry for NCT02240134 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 523 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Montana, which has 42 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Lower Tract Respiratory Infection appearing as the primary indexed condition, and to 3 interventions — of which Education Intervention (Tx1) is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT02240134 reports 1 study location spanning 1 distinct geographic area — top geographies include Montana. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
