Prevalence of self-induced vomiting and laxative/medication abuse among female adolescents: A longitudinal study

Abstract

In order to assess the prevalence and stability of weight reduction techniques utilized by adolescent females, three comprehensive samples of middle school and high school students (ages 12-18) were surveyed in the springs of 1984, 1989, and 1992. All participants were enrolled in the same school district to ensure that the groups were demographically equivalent. The results demonstrated a significant decrease in the use of appetite suppressants among high school students. However, middle school females reported a significant increase in medication use and self-induced vomiting during the same 7-year period. Laxative abuse has persisted unchanged for a small segment of both populations.
