若い女性の肥満の問題は、将来の慢性疾患やリプロダクティブヘルスへの影響、次世代の肥満につながる。したがって、これらの女性の行動変容を効果的に支援することが必要である。本研究の目的は、若年女性の食欲と摂食行動の問題点を明らかにするために、食事関連指標を評価することであった。 18～39歳の健康な女性を登録した。心拍知覚タスクスコアを用いて間受的意識（IA）を定量化した。摂食行動は3つの方法で検討した。3因子摂食質問票（TFEQ）、主観的な食欲感覚の視覚的アナログ尺度、および食品消費テストであった。 全参加者のうち、太りすぎの女性15名と正常体重の女性50名を分析した。太りすぎの女性は、心拍知覚タスクのスコアに応じて2つのグループにクラスター化された：低スコアグループ（低IA [OW-LOW]を持つ太りすぎの女性）と高スコアグループ（高IA [OW-HIGH]を持つ太りすぎの女性）。OW-LOW群では、正常体重の女性と比較して、空腹スコアの食間変化が有意に小さかった。OW-HIGH群のTFEQ上の抑制スコアは正常体重の女性に比べて有意に高く，空腹時の前向き消費スコアは正常体重で心拍知覚タスクスコアが高い女性の方が有意に高かった。 体重過多の若い女性は、食欲や摂食行動が異なる2群に特徴づけられ、過食のリスクと関連していた。食欲の特徴は，正常体重の集団の肥満リスクの高さと関連していた．IAレベルに合わせた個別化された介入は、肥満の改善と予防に役立つかもしれません。

The problem of obesity in young women leads to future chronic diseases, effects on reproductive health, and next-generation obesity. Thus, it is necessary to provide effective support for these women's behavioral change. The purpose of this study was to evaluate dietary-related indicators to clarify the appetite and eating behavior problems among young women. Healthy women 18-39 years of age were enrolled. Interoceptive awareness (IA) was quantified using a heartbeat perception task score. Eating behavior was examined in three ways: Three-Factor Eating Questionnaire (TFEQ), visual analog scales of subjective appetite sensations, and a food consumption test. In all, 15 participants who were overweight and 50 with normal weight were analyzed. The overweight women were clustered into two groups according to the heartbeat perception task score: a low-score group (women with overweight who have low IA [OW-LOW]) and high-score group (women with overweight who have high IA [OW-HIGH]). The OW-LOW group had significantly smaller intermeal changes in hunger score compared with women with normal weight. The disinhibition score on the TFEQ for the OW-HIGH group was significantly higher than the normal-weight women, and the prospective consumption score in the fasting condition was significantly higher in women with normal weight and a high heartbeat perception task score. Overweight young women were characterized into two groups with different appetite and eating behavior, which is connected to the risk of overeating. An appetite characteristic is associated with a high risk of obesity among the normal-weight population. Individualized interventions tailored to the IA levels may help in improving and preventing obesity.
