Understanding daily life experiences of women who smoke: The role of smoking-related weight control expectancies

•Smoking-related weight control expectancies were examined as a predictor of women’s daily life weight-related experiences.•Higher smoking-related weight control expectancies were associated with greater perceived smoking-related reductions in hunger.•Higher smoking-related weight control expectancies were associated with more end-of-day perceived weight gain.•Smoking-related weight control expectancies were unrelated to end-of-day bloating, daily exercise, or sitting. Smoking-related weight control expectancies are a motivational factor for maintaining cigarette use, particularly among women. Yet, less research has investigated the physiological and behavioral daily life weight-related experiences of women with smoking-related weight control expectancies. Increased research could contribute to understanding of maintenance factors for this group of smokers as well as unique intervention targets. Female smokers completed a baseline survey of smoking-related weight control expectancies and 35-days of ecological momentary assessment of physiological (i.e., smoking-related reduction in hunger, end-of-day perceived weight gain and bloating) and behavioral (i.e., daily exercise and sitting) weight-related experiences. Higher smoking-related weight control expectancies were associated with perceived smoking-related reductions in hunger and end-of-day perceived weight gain. Smoking-related weight control expectancies did not significantly associate with end-of-day bloating, daily exercise, or sitting. Given these findings, smoking-related weight control expectancies may maintain smoking in order to reduce hunger and to cope with perceived fluctuations in weight in daily life. It is critical for smoking cessation programs to assess smoking-related weight control expectancies and implement targeted treatments for these women.
