A Smoking Cessation Intervention During Pregnancy in Argentina and Uruguay

January 29, 2015 updated by: Ezequiel Garcia Elorrio, Institute for Clinical Effectiveness and Health Policy
Argentina and Uruguay are among the countries with the highest proportion of pregnant women who smoke. The implementation of an effective smoking cessation intervention would have a significant impact on the health of mothers and children. The "5 A's" (Ask, Advise, Assess, Assist, Arrange) is a strategy consisting of a brief cessation counseling session of 5-15 minutes delivered by a trained provider, which is considered the standard of care worldwide. However, it is under used in Argentina and Uruguay. We will conduct a two-arm, parallel cluster randomized controlled trial of an implementation intervention in 20 prenatal clinics in Argentina and Uruguay. Our primary hypothesis is that the intervention is feasible in prenatal clinics in Argentina and Uruguay and will increase the frequency of women receiving tobacco use cessation counseling during pregnancy. Our secondary hypothesis is that the intervention will decrease the frequency of women who smoke by the end of their pregnancies. Prenatal clinics will be randomly allocated to either an intervention or a control group after a baseline data collection period. Midwife facilitators in the ten intervention clinics will be identified and trained to deliver the "5 A's" to pregnant women and will then disseminate and implement the program. The ten clinics in the control group will continue with their standard in-service activities. A follow-up data collection will be conducted immediately after delivery. The intervention will be tailored by formative research to be readily applicable to local prenatal care services at busy maternity hospitals, as well as to be acceptable to local pregnant women and health providers. The study will be conducted in 48 months.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

12 years to 49 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Frequency of women receiving the cessation smoking advice
Time Frame: Interviews during the first 12 hours after delivery
Frequency of women receiving the "5 A's" (ask smoking status of all women; advise smokers to quit; assess their willingness to make a quit attempt; assist their attempt by providing skills and materials for tobacco cessation; arrange: monitor smoking status at all prenatal visits) in women having prenatal care at the participating prenatal clinics.
Interviews during the first 12 hours after delivery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Frequency of women who smoke at the end of pregnancy
Time Frame: Interviews and saliva samples during the first 12 hours after delivery
Frequency of women who smoke at the end of pregnancy: Women will be interviewed during their postpartum hospital stay and saliva samples will be taken for cotinine analysis.
Interviews and saliva samples during the first 12 hours after delivery
Frequency of providers' positives attitudes and readiness to change
Time Frame: 6 months before and after the implementation of the intervention
Frequency of positives attitudes and readiness to provide counseling for smoking cessation to women following the "5 A's" model among midwives working at participating prenatal clinics. Assessed through a self-administered questionnaire.
