Male adolescents seem to be at a higher risk of developing eating
disorder symptoms, according to a new study. This prevalence study was conducted to amongst adolescents of various ethnic groups.
The research also found that black females are least likely to practice weight control.
The study, one of the first to examine trends in adolescent weight control behaviours over a 10-year period, found that the incidence of these behaviours in male adolescents significantly increased, while black females appear to resist pressure to pursue thinness.
Led by Y. May Chao of Wesleyan University in Middletown, CT, researchers examined data from nationally representative samples of high school students from 1995 to 2005. The data was available via the Youth Risk Behaviour Surveillance System (YRBSS), a survey conducted every two years since 1991 by the Centers for Disease Control and Prevention to assess the prevalence of health-risk behaviours among teens.
The results showed that the prevalence of dieting and diet product use among female adolescents significantly increased between 1995 and 2005 and as did the prevalence of all weight control behaviours (including dieting, diet product use, purging, exercise and vigorous exercise) among males.
The data suggested that black female adolescents are the least likely to practice weight control, while white female adolescents are the most likely. Among males, white adolescents are the least likely to practice weight control and Hispanic adolescents are the most likely.
