수도권에 거주하는 20대 여성의 비만도에 따른 심리적 요인과 식행동 및 건강 관련 삶의 질 비교

Abstract

Abstract This study was carried out to analyze the relationship between body mass index (BMI) and general characteristics, psychological factors, eating habits, dietary behaviors, and health related quality of life using survey of 335 women aged 20 to 29 years in the Seoul and Kyungin areas. The 335 study subjects were divided into 4 groups by BMI (㎏/㎡) levels; normal group(18.5BMI22.9), overweight group(23.0BMI24.9), mild obesity group(25.0BMI29.9), and heavy obesity group (BMI30) by Asian-Pacific obesity index criteria. The family income of the heavy obesity group was significantly (p<0.05) less than that of the normal weight group. Psychological factors, such as stress and depression of the normal weight group tended to be higher than those of overweight and obesity groups. The higher BMI level had the lower self-efficacy(p<0.05) among all subjects. As the BMI level increased, the preference for sweet, salty, and hot taste was significantly high. We found that normal weight women had healthier eating habits and dietary behaviors and a higher level of health-related quality of life than did those who were overweight, mildly obese, and heavily obese women. Overweight and mildly and heavily obese women were strongly associated with decreased physical and mental health related quality of life. Therefore, weight loss is desirable, and is likely to be beneficial for health-related quality of life in obese adult women. In conclusion, this study contains evidence to suggest that obesity management programs including different strategies according to obesity are required to determine the types of programs that are suitable for adult women, prior to their initiation of a program. The findings are helpful to inform researchers and practitioners who are seeking to implement appropriate strategies to create positive changes in the health behaviors of obese adult women.Key words: BMI, psychological factors, dietary behaviors, health-related quality of life
