Who could benefit from this research

Could help

Ideal candidates would be new mothers who have recently given birth, previously smoked, and are at risk of relapsing.

Less likely to help

Patients who have never smoked or are not in the postpartum period would not directly benefit from this specific intervention.

What this research studies

Many new mothers who quit smoking during pregnancy start again shortly after giving birth, which can harm both themselves and their babies through secondhand smoke. We are exploring if a combination of hormones, specifically increasing progesterone and decreasing estradiol, can help prevent this relapse. Our previous work suggests that progesterone may reduce cravings and and help mothers stay smoke-free. We also saw that another hormone treatment, DMPA, was linked to longer periods of not smoking in other women. This approach aims to support new mothers in maintaining their smoke-free lifestyle.

Why it matters

Potential benefit: If successful, this approach could offer new mothers a way to prevent smoking relapse after childbirth, leading to better health for them and their infants.

How similar studies have gone: Preliminary data from this team and other research suggest that progesterone can have protective effects on addictive behaviors, indicating a basis for this approach.
