Postpartum Behavioral Sleep Intervention for Smoking Relapse Prevention: A Pilot Trial

Area of Science:

• Public Health
• Sleep Medicine
• Addiction Research

Background:

• Postpartum smoking relapse rates are alarmingly high, ranging from 70-90%.
• Standard relapse prevention interventions have shown limited effectiveness in the postpartum period.
• Poor sleep quality is a common issue for postpartum mothers and may contribute to smoking relapse.

Purpose of the Study:

• To evaluate the effects of a combined relapse prevention and behavioral sleep intervention on sleep quality and smoking relapse in postpartum mothers.
• To assess the feasibility and impact of a novel intervention targeting both sleep and smoking cessation.

Main Methods:

• A pilot study involving 28 postpartum mothers randomized to either a combined intervention or relapse prevention alone.
• Objective (actigraphy, CO levels) and subjective (questionnaires, sleep diaries) measures of sleep and smoking status were collected at baseline, 8 weeks, and 12 weeks postpartum.
• Timeline Followback (TLFB) and salivary cotinine analysis were used to corroborate smoking abstinence and assess substance use.

Main Results:

• The combined intervention significantly improved maternal nighttime sleep duration (48 min), consolidated sleep bouts (42 min), and sleep efficiency (to >85%).
• Subjective ratings of sleep disturbance were also reduced post-intervention.
• While the link between improved sleep and abstinence was inconclusive, post-hoc analyses revealed that social support and the presence of an additional support person were positively correlated with smoking abstinence.

Conclusions:

• Behavioral interventions can effectively improve sleep in postpartum women with a history of smoking.
• Social-emotional support is a critical factor in preventing smoking relapse among postpartum mothers.
• Future research should explore the synergistic effects of sleep interventions and robust social support systems for smoking cessation in this population.
