Body Weight and Suicidal Behavior in Adolescent Females: The Role of Self-Perceptions.

This study examines the relationship between body weight and suicidal behaviors using a rich longitudinal data set of a large nationally-representative sample of female adolescents to account for a number of confounding factors. The study explores the relationship, not only between actual weight status and suicidal behaviors, but also between self-perception of weight and suicidal behaviors. METHOD: Using data from a nationally-representative sample of adolescents in the United States, the study ascertains the effect of body weight status on suicidal behaviors by estimating endogeneity-corrected models including school-level fixed effects to account for bi-directionality and unobserved confounders. Actual body weight status was calculated using interviewer-measured height and weight. The study also used a measure of self-perceived weight status to compare how actual versus self-perceived weight status affects suicidal behavior. Thinking about committing suicide and attempting to commit suicide in the past 12 months were utilized as dichotomous measures of suicidal behaviors. Potential mediators between suicidal behaviors and weight status such as family history of suicide, participation in risky health behaviors and parental characteristics were also controlled for in the analysis.
