Wood Smoke Interventions in Native American Populations
NCT02240069 · View on ClinicalTrials.gov ↗
Study Summary
A critical need exists for efficient community-based interventions aimed at reduction of environmental exposures relevant to health. Biomass smoke exposures due to residential wood heating are common among rural Native American communities, and such exposures have been associated with respiratory disease in susceptible populations. In many of these communities wood stoves are the most economic and traditionally preferred method of residential heating, but resource scarcity can result in burning of improper wood fuels and corresponding high levels of indoor particulate matter. Community-based participatory research techniques will be used to adapt intervention approaches to meet the cultural context of each participating community. At the community level, investigators will facilitate local development of a tribal agency-led wood bank program ensuring that elderly and/or persons with need have access to dry wood for heating. At the household level, investigators will use a three arm randomized placebo-controlled intervention trial to implement and assess education/outreach on best burn practices (Tx1). The content and delivery strategies of the education intervention will be adapted to each community according to stakeholder input. This educational intervention will be evaluated against an indoor air filtration unit arm (Tx2), as well as a placebo arm (Tx3, sham air filters). Tx3 will be used in comparison with the other two treatment arms to evaluate the penetration and efficacy of the community-level wood bank program. Outcomes will be evaluated with respect to changes in pulmonary function measures and respiratory symptoms and conditions among household elders. The investigators hypothesize that locally-designed education-based interventions at the community and household levels will result in efficacious and sustainable strategies for reducing personal exposures to indoor particulate matter, and lead to respiratory health improvements in elderly Native population

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT02240069
The ClinicalTrials.gov registry entry for NCT02240069 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 149 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 2 conditions, with Respiratory; Disorder, Functional, Impaired appearing as the primary indexed condition, and to 3 interventions — of which Air Filtration Unit Treatment (Tx2) 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: NCT02240069 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.
