Trial Summary

What is the purpose of this trial?

The investigators aim to address the following specific aims: * Determine the efficacy of Prog in preventing postpartum smoking relapse and reducing smoking relapse risk factors. * Examine the effects of this maternal smoking intervention on infant health. * Examine racial and ethnic differences in intervention outcomes.

Will I have to stop taking my current medications?

The trial requires that you do not use nicotine replacement therapy or smoking cessation medications, except for e-cigarettes. Also, you cannot participate if you are taking drugs that may interfere with progesterone treatment.

Is progesterone treatment generally safe for humans?

Depot medroxyprogesterone acetate (DMPA), a form of progesterone, is widely used as a contraceptive, but some users report side effects like menstrual disturbances and weight gain. There are also concerns about its association with depressive symptoms and breast cancer, though the evidence is not conclusive. ^{1 2 3 4 5}

How is the drug Progesterone for Postpartum Smoking Relapse different from other treatments?

This treatment is unique because it uses depot medroxyprogesterone acetate (DMPA), a long-acting form of progesterone, which is typically used for contraception and may influence hormonal changes postpartum. Unlike other treatments for smoking relapse, it is administered as an injection, which provides a sustained release of the hormone, potentially affecting mood and behavior related to smoking. ^{3 5 6 7 8}

Treatment Details

Interventions

• Depot-Medroxyprogestereone Acetate
• Placebo Injection
• Placebo Oral Tablet
• Progesterone 200 MG Oral Capsule

Trial Overview The study tests if Progesterone (a hormone capsule) can help new moms avoid starting smoking again after giving birth compared to a placebo (a dummy pill). It also looks at how this might benefit the baby's health and explores if there are differences in outcomes based on race and ethnicity.

Findings from Research

Depot medroxyprogesterone acetate (DMPA) is a highly effective contraceptive method, with no pregnancies reported within three months of injection among 363 women treated over 20 years, and a high acceptability rate with an average of 6.3 injections per subject.

While some women experienced menstrual disturbances, only 7.3% discontinued due to these issues, and the median delay in return to fertility for those wishing to conceive was 9.2 months, indicating that DMPA is generally safe and well-tolerated.

In a study of 86 female adolescents using depot medroxyprogesterone acetate (DMPA) for contraception, factors such as race, gynecologic age, and baseline weight were not significantly associated with weight gain during the first 10 to 14 weeks after starting the treatment.

Despite concerns about weight gain linked to DMPA, this study found no significant differences in weight change based on the evaluated characteristics, suggesting that individualized counseling may not need to focus on these specific factors.

In a study of 5,073 women, the use of postpartum depot medroxyprogesterone acetate (DMPA) was not linked to an increase in postpartum depressive symptoms, as indicated by the Patient Health Questionnaire 9 (PHQ-9) screening results.

Despite previous concerns about DMPA potentially causing depression, this research suggests that its use in the immediate postpartum period is safe and should not deter women from using it as a contraceptive method.

In a study of 1864 New Zealand women aged 25 to 54, 13.7% reported using depot medroxyprogesterone acetate (DMPA) as a contraceptive, with higher usage among Maori women and those with lower income and education levels.

While DMPA has a low contraceptive failure rate of 0.9 per 100 woman-years, many users discontinue due to side effects like menstrual disturbances and weight gain, indicating that its acceptability is limited despite its effectiveness.

A pooled analysis of two case-control studies involving 1,768 women with breast cancer and 13,905 controls found that the overall relative risk (RR) of breast cancer for women who had ever used depot medroxyprogesterone acetate (DMPA) was 1.1, indicating no significant increase in risk.

However, recent or current users of DMPA (within the last 5 years) had a higher estimated RR of 2.0, suggesting that the increased risk may be related to enhanced detection of tumors or accelerated growth of existing tumors, while women who used DMPA more than 5 years ago showed no increased risk.

A study of 404 postpartum women found that administering depot medroxyprogesterone acetate (DMPA) immediately after delivery does not significantly affect the development of postpartum depression (PPD), as indicated by similar Edinburgh Postnatal Depression Scale (EPDS) scores between those who received DMPA and those who did not.

The rates of PPD diagnosis were also comparable, with 10.9% of women receiving DMPA diagnosed with PPD versus 14.1% in the non-DMPA group, suggesting that DMPA does not increase the risk of developing PPD.

The study involving 183 mothers assessed the impact of immediate postpartum depot medroxyprogesterone (DMPA) on breastfeeding duration, suggesting a potential negative effect, although it was not statistically significant (p=0.24).

After adjusting for confounding factors, the hazard ratio indicated a 22% higher risk of breastfeeding cessation associated with DMPA use, but the evidence remains inconclusive, highlighting the need for further research.

Among low-income new mothers in upstate New York, 31.3% received postpartum DMPA, with 62.6% of those receiving it before hospital discharge, highlighting the importance of timely administration to prevent unintended pregnancies.

The study found significant variability in DMPA administration patterns across different hospitals, suggesting a need for further research to improve access and ensure appropriate candidates receive this contraceptive method.
