Biomarker Feedback to Motivate Tobacco Cessation in Pregnant Alaska Native Women
An observational study of Cancer and Tobacco Use, run by Mayo Clinic at 1 site in United States.
Trial summary
Use of tobacco is very high among Alaska Native women. The investigators are conducting a three phase study. The first phase will examine biomarkers of tobacco exposure in pregnant women and their newborns. The second phase is a qualitative study to translate the biomarker findings into intervention messages. Read more about this study

- Ages Up to 50 years

- Child, Adult
Study population: Pregnant women will be recruited through prenatal care
Who may be able to join
- To be eligible the woman must:
- be Alaska Native,
- be aged 18 years or older,
- provide written informed consent,
- be currently pregnant (1st, 2nd or 3rd trimester), and
- plan to deliver at the ANMC. An additional inclusion criterion for current tobacco users is any use in the past 7 days. Our preliminary studies indicate that women may use more than one form of tobacco. To enhance feasibility of recruitment and generalizability, women will not be excluded if they use more than one form of tobacco. Instead, group composition will be based on the primary type of tobacco used. An additional inclusion criterion for non-tobacco users is no use of any form of tobacco in the last 6 months.
Who cannot join
- Women will be excluded if they have used nicotine replacement therapy (NRT) or have participated in a behavioral or pharmacological tobacco cessation program within the past 30 days.
- Alcohol and other drug use will not be an exclusionary criterion because the biomarkers are specific to tobacco exposure.

About this study
Official title: Biomarker Feedback to Motivate Tobacco Cessation in Pregnant Alaska Native Women: Phase 1
Use of tobacco is very high among Alaska Native women. The investigators are conducting a three phase study. The first phase will examine biomarkers of tobacco exposure in pregnant women and their newborns. The second phase is a qualitative study to translate the biomarker findings into intervention messages. The third phase is a pilot of the biomarker feedback intervention compared with a control condition.
Read the detailed description
Developing effective tobacco cessation interventions during pregnancy for American Indian and Alaska Native people is a national priority and will contribute to the U.S. public health objective of reducing tobacco-related cancer health disparities. The proposed project builds on our successful partnership with the Alaska Native community and previous work with Alaska Native pregnant women. We propose to develop and test a novel biomarker feedback intervention relating cotinine levels in the urine of pregnant women with the woman and infant's likely exposure to the tobacco specific nitrosamine and carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone) (NNK). This 5-year project will be conducted in three phases. In Phase 1 we will utilize a non-randomized, clinical observational trial to examine biomarkers of nicotine and carcinogen exposure (urine cotinine and total NNAL [a metabolite of NNK], respectively) among 150 maternal-infant pairs with assessments conducted during pregnancy and at delivery. In Phase 2, we will obtain qualitative feedback on the findings from Phase 1 through individual interviews conducted with 32 women who use tobacco to develop the biomarker feedback intervention messages. Phase 3 will consist of a formative evaluation of the biomarker feedback intervention with 80 pregnant women using a two-group randomized design to assess the intervention's feasibility and acceptability, and the biochemically confirmed abstinence rate at the end of pregnancy. All phases of the project will be guided by a Community Advisory Committee. Each phase is an important step to advance our understanding of the potential for biomarker feedback as a strategy to help Alaska Native pregnant women quit tobacco use. The potential reach of the intervention is significant from a public health perspective as over 600 tobacco users deliver each year at the Alaska Native Medical Center in Anchorage where the proposed project will take place. Developing effective interventions for tobacco cessation during pregnancy is important to reduce adverse health consequences for the mother and neonate and future risk of tobacco-caused cancers.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 2 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: finished, as of the sponsor's last update on 19 Dec 2017. 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 United States. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
NNAL (time frame: delivery). 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 19 Dec 2017.
