Unhealthy weight control behaviors and related risk factors in Massachusetts middle and high school students.

Unhealthy weight control behaviors may be precursors to clinical eating disorders; therefore, it is important to identify these actions, and what may trigger them, as early as possible. We used 2009 and 2011 Massachusetts Youth Health Survey data for middle and high school students. We studied age, sex, and race disparities related to unhealthy weight control behaviors in conjunction with other risk factors such as body mass index (BMI), body weight perception, involvement in bullying, and depressive symptoms. The surveys were completed in public schools. Bivariate and multinomial regression analyses were conducted to assess associations between weight control behaviors and BMI categories, body weight perception, bullying involvement, and depressive symptoms. Poor body weight perception, bullying involvement, and depressive symptoms were associated with significantly elevated odds of reporting unhealthy weight control behaviors in both middle and high school students. Most patterns were consistent for middle and high school students, with obesity and bullying involvement being prevailing risks for high school students. Though females were more likely to report unhealthy weight control behaviors we also showed the rarely presented prevalence of male involvement in disordered eating behaviors including those who perceived themselves to be underweight. Health education classes and school-based interventions may be two strategies to help prevent the development of unhealthy weight control behaviors. Continuation of youth surveys that gather data on weight control behaviors and known risk factors is essential for observing changes in behaviors over time.
