Abstract

ObjectiveWe aimed to examine the trajectories, predictors, and health effects of sleep quality and duration among pregnant smokers.

MethodsWe used data of 58 pregnant smokers enrolled in a smoking cessation intervention study conducted in Buffalo, NY during 2015-2016. Sleep quality and duration were measured with Pittsburgh Sleep Quality Index (PSQI) repeatedly at 3 study visits: pre-test, post-test, and end-of-pregnancy.

ResultsThe sleep quality of pregnant smokers decreased during pregnancy while sleep duration did not changed substantially. At the pre-test, depression and heavy smoking were associated with lower sleep quality. Although not significantly, poor sleep (vs. good sleep) at pre-test seemed to predict a higher risk of failure in smoking cessation (27.8% vs. 16.7%) and insufficient gestational weight gain (25.0% vs. 14.3%).

ConclusionDepression and heavy smoking negatively affect sleep quality among pregnant smokers, which could potentially lead to failure in smoking cessation and insufficient weight gain.

• Specific Aim 1: to track sleep quality and duration throughout pregnancy

• Specific Aim 2: to examine the effects of depression, mood disorder, pre-pregnancy weight and smoking frequency on pregnant mothers’ sleep quality and duration

• Specific Aim 3: to examine the impact of pregnant mothers’ sleep quality and duration on gestational weight gain and success in smoking cessation

• Increase in depression severity and smoking frequency negatively impacts sleep quality among pregnant smokers

• Poor sleep quality could potentially increase the risk of failure in smoking cessation and insufficient gestational weight gain
