Stability and change in patterns of concerns related to eating, weight, and shape in young adult women: A latent transition analysis.

Although college women are known to be at high risk for eating-related problems, relatively little is known about how various aspects of concerns related to eating, weight, and shape are patterned syndromally in this population. Moreover, the extent to which various patterns represent stable conditions or transitory states during this dynamic period of development is unclear. The present study used latent class and latent transition analysis (LCA/LTA) to derive syndromes of concerns related to eating, weight, and shape and movement across these syndromes in a sample of 1,498 women ascertained as first-time freshmen and studied over 4 years. LCA identified 5 classes characterized by (a) no obvious pathological eating-related concerns (prevalence: 28%–34%); (b) a high likelihood of limiting attempts (prevalence: 29%–34%); (c) a high likelihood of overeating and binge eating (prevalence: 14%–18%); (d) a high likelihood of limiting attempts and overeating or binge eating (prevalence: 14%–17%); and (e) pervasive bulimiclike concerns (prevalence: 6%–7%). Membership in each latent class tended to be stable over time. When movement occurred, it tended to be to a less severe class. These findings indicate that there are distinct, prevalent, and relatively stable forms of eating-related concerns in college women. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
