About this study

We developed and established the efficacy of a theory-based, culturally- and gender-relevant Community Health Worker (CHW) intervention for low-income Brazilian women that augments the tobacco cessation program offered through the public health system. This study seeks to adapt this CHW-delivered tobacco cessation program to be integrated with mHealth support through mobile devices (App). During phase I we will make the adaptations and determine feasibility of a CHW-delivered intervention that is integrated with a mHealth tobacco cessation application (interactive App for participants and tracking system for CHWs) through formative assessments among all involved stakeholders, pretesting, and pilot testing of the intervention. In phase II we will assess the effectiveness of the integrated CHW-mHealth tobacco cessation intervention through a group randomized trial with towns as the unit of randomization (8 towns, N=344). The comparison group will consist of a home visit by a CHW during which the participant is scheduled to attend the tobacco cessation program at the neighborhood public health clinic). We hypothesize that at 6-months, women smokers who receive the integrated CHW-mHealth intervention will have significantly higher 7-day point prevalence abstinence (defined as no cigarettes in the past 7 days) than women smokers in the control condition. If shown to be effective, this approach could be utilized as a model for a population-based intervention in low-resource settings, including rural and disadvantaged women in the U.S.

We developed and established the efficacy of a theory-based, culturally- and gender-relevant Community Health Worker (CHW) intervention for low-income Brazilian women that augments the tobacco cessation program offered through the public health system. This study represents the continuation of our tobacco control efforts in Brazil by proposing the adaptation of this CHW-delivered tobacco cessation program to be integrated with mHealth support through mobile devices (App). We are proposing an integrated CHW-mHealth application that (a) is culturally- and gender-relevant, (b) is theory-based (Social Cognitive Theory), (c) considers the existing structure of the Brazilian health care system, and (d) will be adapted based on an efficacious intervention as well as salient features of other mHealth applications that have been shown to be successful in engaging users. During phase I we will make the adaptations and determine feasibility of a CHW-delivered intervention that is integrated with a mHealth tobacco cessation application (interactive App for participants and tracking system for CHWs) through formative assessments among all involved stakeholders, pretesting, and pilot testing of the intervention. In phase II we will assess the effectiveness of the integrated CHW-mHealth tobacco cessation intervention through a group randomized trial with towns as the unit of randomization (8 towns, N=344). The comparison group will be the same as the previous intervention (consisting of a home visit by a CHW during which the participant is scheduled to attend the tobacco cessation program at the neighborhood public health clinic) to allow for comparisons. We hypothesize that at 6-months, women smokers who receive the integrated CHW-mHealth intervention will have significantly higher 7-day point prevalence abstinence (defined as no cigarettes in the past 7 days) than women smokers in the control condition. Self-report will be verified through measurement of exhaled carbon monoxide levels among 30% of participants. If shown to be effective, this approach could be utilized as a model for a population-based intervention in low-resource settings, including rural and disadvantaged women in the U.S.

Questions about this trial

What is this clinical trial studying?

A study testing Integrated tobacco cessation intervention delivered by Community Health Workers with the support of an App (mHealth) + Tobacco cessation program at the public health system in people with Tobacco Cessation, run by University of Alabama at Birmingham at 1 site in Brazil.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 18 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Isabel C Scarinci, PhD ((205) 975-7177, scarinci@uab.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

7-day point prevalence abstinence (defined as no cigarettes in the past 7 days) (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jun 2026.
