title: A questionnaire survey regarding the support needed byYogoteachers to take care of students suspected of having eating disorders (second report).
abstract: BACKGROUND
  The lowering of the age of onset and chronicity have been key problems related to eating disorders (EDs). As the proportion of teens in the estimated onset ages has increased, it has become important to detect students with EDs and to clarify how they can be supported. Though epidemiological surveys ofYogoteachers (school nurse/health science teachers) have been conducted to inquire about the number of such students, none of these were done according to ED type based on DSM-5. Thus, we conducted a wide area survey in Japan with the goal of proposing a better framework of support forYogoteachers in their efforts to care for students with EDs.
  
  
  METHODS
  A questionnaire survey organized by ED type (based on DSM-5) was administered toYogoteachers working at elementary/junior high/senior high/special needs schools in four prefectures of Japan in 2015, and 1,886 responses were obtained. Based on the results, the encounter rates (the proportion ofYogoteachers who had encountered a student with an ED) were calculated, and factors that could affect the rates were examined by logistic regression analysis.
  
  
  RESULTS
  The order of the encounter rates of the ED types was as follows: Anorexia Nervosa (AN) > Bulimia Nervosa (BN) > Avoidant/Restrictive Food Intake Disorder (ARFID) > Binge Eating Disorder (BED) > Others. The factors significantly affecting the rates were "location, school type, number of students, experience years, and AN knowledge" for AN, "school type, experience years, and BN knowledge" for BN, "school type, experience years, and BED knowledge" for BED, "location, experience years, and ARFID knowledge" for ARFID, and "school type, experience years, and Others knowledge" for Others.
  
  
  CONCLUSIONS
  Because the encounter rate of AN was the highest, providing support for AN would be the most effective. Moreover, one factor that affected the encounter rate of all ED types was ED knowledge. In addition to this, senior high schools had the highest encounter rates for AN, BN and BED, and special needs schools had the highest rates for Others. These findings imply that, in order to detect and support ED students at an early stage, it is necessary to offer knowledge of the most prevalent ED types toYogoteachers at the corresponding school type.
