Abstract
Background: As the proportion of teens in the onset ages has increased, it has become important to detect eating disorder (ED) students early in school and clarify the way of support. Though epidemiological surveys of Yogo teachers have been conducted to inquire the number of ED students, none of these were based on DSM-5. Thus, we conducted a wide area survey in Japan for proposing a better framework of support for Yogo teachers in the early detection/support of ED students. Methods: A questionnaire survey organized by ED type (based on DSM-5) was administered to Yogo teachers working at elementary/junior high/senior high/special needs schools in four prefectures of Japan in 2015, and 1886 responses were obtained. Based on the results, the encounter rates (the proportions of Yogo teachers who had met ED students) were calculated, and factors affecting them were examined by logistic regression analysis. Results: The order of the encounter rates of the ED type was 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, BN knowledge for BN, location, school type, experience years, BED knowledge for BED, location, experience years, ARFID knowledge for ARFID and school type, experience years, Others knowledge for Others. Conclusions: Since the encounter rate of AN was highest, providing support for AN would be effective. Moreover, a factor affecting the rate of all ED types was the ED knowledge. Senior high schools had the highest rates for AN, BN and BED, and special needs schools had the highest for others. These findings imply that for detecting/supporting ED students early, it is necessary to offer knowledge of the corresponding ED type to Yogo teachers at the corresponding school type.
Highlights
The lowering of the age of onset and chronicity have been found to be key problems related to eating disorders (ED) in recent years [1,2].Children with EDs are likely to fall into physical crises and develop growth disorders [3]
It is important to detect students suspected of having EDs early and to clarify the way they are supported in school, since the proportion of teens in the estimated onset age range of ED has increased year by year [5,6]
To improve the way Yogo teachers are supported in their early detection/support of ED students, the encounter rates of EDs in a wide area of Japan were 1 calculated, and the factors that could affect those rates were examined
