Baseline sleep quality is a significant predictor of quit-day smoking self-efficacy among low-income treatment-seeking smokers

Abstract

Compared to non-smokers, smokers have an increased risk for poor sleep quality, which could undermine confidence to quit. This study examined whether baseline sleep quality was associated with quit-day smoking self-efficacy among smokers enrolled in a smoking cessation trial. Treatment-seeking low-income smokers were randomized to either a low-intensity physical activity integrated with standard smoking cessation intervention or standard care cessation only. Poor sleep quality was significantly associated with lower quit-day (week 4) smoking self-efficacy (β = –0.61; standard error = 8.1; p =.03). Over half the samples (53%) reported poor sleep quality, thus addressing baseline sleep quality is an important consideration in smoking cessation programs.
