New contributions to the prevalence of eating disorders in Spanish adolescents: detection of false negatives

Abstract

The prevalence of ED obtained in our study, higher than others found in previous Spanish research, and a relatively high percentage of false negatives both indicate that up to now the prevalence of ED in Spanish adolescents could be underestimated.

Prevalence of eating disorders among adolescent and young adult scholastic population in the region of Madrid (Spain)

“…A second problem with previous Spanish studies, which has been emphasized in recent publications [28,29], concerns their possible underestimation of the prevalence of EDs. Most of the double-stage prevalence studies [30 -33] interviewed only the individuals who scored equal to or above the cutoff point established for the screening instrument; therefore, it is not possible to determine whether false negatives were identified by the instruments administered.…”

Maintained malnutrition produces a progressive decrease in (OPG)/RANKL ratio and leptin levels in patients with anorexia nervosa

“…The prevalence of this disease between adolescents and young adults in Spain is 0.1 % [4]. AN presents osteopenia as one of the most important medical complications, affecting more than 50 % of patients [5].…”

Eating attitudes and barriers to healthy eating and physical activity among a sample of university students in Egypt

“…The prevalence of disordered eating attitudes in the current study was higher compared with other studies in Arabic countries as it was 31.8 and 33.6% among men and women in Kuwait [21] , and ranged from 13.8 to 47.3% among men, and from 16.2 to 42.7% among women in seven Arab countries [17] . Also, the rate was higher compared with rates recorded in more developed countries such as Singapore: 10.5% [22] , Turkey: 45.2% [23] , and Spain: 7.8% [24] . The prevalence of DEAs in the current study was high as our country is less socioeconomically developed compared with these countries.…”
