Area of Science:

  • Psychiatry
  • Adolescent Medicine
  • Epidemiology

Background:

  • Behavioral disorders are prevalent in adolescents.
  • Eating disturbances, substance abuse, and suicidal ideation are significant concerns.
  • Previous research suggests links between trauma and behavioral issues.

Purpose of the Study:

  • To investigate correlations between eating disturbances, drug/alcohol abuse, suicide attempts, and history of sexual abuse in adolescents.
  • To identify patterns of behavioral disorders in a student population aged 16-19.

Main Methods:

  • An epidemiological study involving 434 students (16-19 years old).
  • Anonymous, self-administered questionnaires were used to collect data.
  • Statistical analysis was performed using SPSS/PC Factor software.

Main Results:

  • Adolescents exhibited borderline eating behaviors and distorted body image, with girls more frequently dissatisfied with their bodies.
  • Low self-esteem correlated with abnormal eating behaviors (borderline bulimia).
  • Anorexic and bulimic behaviors significantly correlated with suicide attempts; bulimic behavior linked to drug/alcohol abuse. Sexual abuse victims (2.6% with contact, 13.5% without) showed a tendency towards bulimic behavior.

Conclusions:

  • Significant correlations exist between conduct disorders, eating disturbances (even borderline), and traumatic sexual events.
  • Findings confirm a link between eating disorders and a history of sexual abuse in adolescents.
