Overeating Risk in Overweight Young Women Is Divided into Two Types According to Appetite and Eating Behavior.

ABSTRACT

Background: 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. Methods: 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. Results: 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. Conclusions: 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.
