高校生版食行動尺度の作成と肥満度に関連する食行動要因の検討  [in Japanese] Development of an Eating Behavior Scale for High School Students and Study on the Factors Related to Himando  [in Japanese]

目的(or)背景:若年層の食行動異常は深刻な問題である.しかし,若年の食行動異常をとらえる信頼性の高い質問紙はない.したがって,本研究では,高校生の食行動尺度の開発を行い,肥満度と関連する食行動要因の検討を行うことを目的とする.仮説は,食行動には性差があること,標準体重者と非標準体重者では食行動が異なるという2点である.被験者:高校生785名を被験者とした.男子が642名,女子が143名.方法:30項目からなる食行動の仮尺度を実施した.同時に,身長,体重も調査用紙に回答させた.結果:因子分析の結果抽出された因子は,代理摂食,過食,食べ方,リズム異常,食事内容の5因子であった.食行動に性差があるかどうかを検定したところ,食べ方以外の食行動に性差がみられた.肥満度を独立変数,各食行動因子を従属変数としたANOVAでは,代理摂食,過食,食べ方,食事内容にてグループの主効果がみられた.結論:本研究では,高校生の食行動異常をとらえる尺度の作成に成功した.食行動には性差がみられることがわかった.標準体重者と非標準体重者では食行動が異なることがわかった.

Background ・ Eating behavior is a serious problem among adolescents in Japan. However, there is no reliable questionnaire to assess abnormality of the eating behavior. The purpose of this study is to develop an eating behavior scale for high school students and to investigate the eating behavior factor structure associated with Himand (seriously under weight, slightly under weight, healthy weight range, over weight, obese). Subjects and method : The subjects consisted of 950 high school students (male = 791 ; female = 159). The subjects completed the questionnaire consisting of 30 items. Results : Factor analysis was carried out and five dimensions were identified. Those factors were as follows : CD eating as diversion, (2)overfeeding, (3)eating quickly, (4)irregular eating, (5)content of meals. The abnormality level of eating behavior was higher in the female group than in the male group. The results of ANOVA that was performed with Himando as the dependent variable and five factors of eating behavior, the significant group effect was detected on eating as diversion, overfeeding, eating quickly, and content of meals factors. Conclusion : In this study, we developed an eating behavior scale for high school students. In high school students, gender difference effects their eating behavior. We found that the abnormality level of eating behavior was higher in the very under weight group, slightly under weight group, over weight group and obese group than in the healthy weight range group.
