Farzaneh Saeedzadeh Sardahaee, et al. - A total of 7,268 adolescents (15–19 years) who had completed self-reported questionnaires including items on suicidal ideation (SI, presides above all other causes of death in individuals aged 15–39 years), disordered eating (DE), body size and weight perception were recruited by the researchers in order to carry out a population-based study on a sample of more than 7,000 adolescents and to investigate the correlation between SI and DE and its related traits. In the total population, the prevalence of SI was 23.1%. Both girls and boys who reported DE assessed their body size as not "about the same as others" or were "unhappy about their weight" had between twofold to fivefold rise in odds for SI and these incremental risks were recognized independent of sex, age, body mass index, and socioeconomic status. Among boys, higher odds for SI were noted. Hence, a clear correlation between SI and DE was concluded and its related traits, in both genders, particularly in males. Moreover, among adolescents, special attention should be given to the early discovery of DE traits.
