Abstract

We aimed at assessing psychological variables and eating behaviors on quality of diet and life in South Korean women according to their weight status. Socio-psychology, eating behavior, quality of diet and quality of life data were assessed in 114 women (mean age: 34.5 ± 8.09 years). NEO Personality Inventory (NEO-PI-RS) and coping styles questionnaire were used to assess socio-psychology variables, and eating behavior was assessed using the Eating Attitudes Test-26 (EAT-26), Dutch Eating Behavior Questionnaire (DEBQ), and General Food Craving Questionnaire Test (G-FCQ-T). Quality of diet was analyzed by Diet Quality Index-international (DQI-I), and obesity-related quality of life was evaluated using the Korean Obesity-related Quality of life Scale (KOQOL). Significant differences were in the psychological variables and eating behaviors in the obese group than the normal and overweight groups (p < 0.05). The overall score of DQI-I was significantly lower in the obese group than that of their counterparts (p < 0.05). BMI was positively correlated with neuroticism, emotional eating, and obesity-related quality of life, and negatively correlated with diet quality. Neuroticism was positively correlated with emotional eating and food craving. Emotional eating was positively correlated with obesity-related quality of life. In conclusion, women with a higher BMI had significantly more problematic eating behaviors, poor diet quality and quality of life.
