Smoking and weight control in adolescent females.
This paper examines the association between smoking and various weight control techniques among adolescent girls in two school-based samples. Previous studies have relied heavily on clinical trials of adults and have focused mainly on dietary restraint rather than purging behavior. This study seeks to determine whether purging is associated with smoking and if purging and dietary restraint effects upon smoking are additive or synergistic. Data from adolescent girls were gathered from two school-based surveys conducted in the upper Midwest. Assessments were conducted for smoking, dietary restraint, diet pill use, and purging. Logistic regression was used to test for main and interaction effects. Analysis revealed significant associations between smoking and weight control. Purging was more highly associated with smoking than dietary restraint or diet pill use. The form of these associations was interactive rather than additive in both data sets. Nonpurging girls were significantly more likely to smoke if they were dieting or using diet pills than if they were not practicing dieting behavior. Thus, the effect of dieting and diet pill use on smoking is dependent on purging behavior. Weight control is associated with smoking behavior in adolescent girls but the form of these associations may be more complex than originally thought. Future research is needed to determine if there are two subtypes of smoking-weight control girls.
