ABSTRACT Objective While previous studies have shown a link between cigarette smoking and disordered eating (DE), it is less clear whether this association can be explained by attempts to control weight and/or temperament. This study had two aims: to examine weight/shape and DE symptomatology associated with weight control‐related smoking and disordered eating; second, to investigate whether temperament‐based factors explain the association between compensatory smoking and weight and shape‐related characteristics, and disordered eating symptoms. Method Female twins ( N = 1,002) from the Australian Twin Registry, aged 28–39 years, were assessed by interview yielding lifetime diagnostic information of disordered eating and use of cigarette smoking for weight control. Self‐report measures of temperament were available. Results Women who had never smoked (50.6%, n = 495) or had smoked for reasons other than weight and shape control (42.5%, n = 415) were generally not differentiated with respect to indicators of disordered eating. Women who smoked for reasons primarily associated with weight and shape control (6.9%, n = 67) had significantly higher levels of disordered eating than non‐smokers identified as being higher levels of purging (OR = 4.55, 95% CI = 2.41–8.59) and fasting (OR = 9.32, 94% CI = 4.43–19.90) but not objective binge episodes (OR = 1.69, 95% CI = 0.71–3.99). Of those women diagnosed with lifetime eating disorders, weight‐control smokers had higher levels of purging (OR = 4.22, 95% CI = 1.13–15.80) than those who did not. There were no differences in temperament. Discussion Results support co‐occurrence of smoking for weight control and purging in both community and clinical groups, and indicate this association is related to weight control and not temperament. © 2014 Wiley Periodicals, Inc.
