The study aim was to investigate the relationship between adolescents' physical activity and subjective health perceptions and determine whether body mass index (BMI), an obesity-related indicator, had a mediating or moderating effect on this relationship. To achieve the purpose of this study, raw data from the 18th Youth Health Behavior Online Survey (2022) were used, and data from 23,612 people were ultimately selected for the research analysis. A confirmatory factor analysis and structural equation modeling were applied to the data, and bootstrapping techniques were used to verify the mediating effect. To verify the moderating effect, a multigroup analysis of the structural equation model was applied to calculate pairwise parameter comparison values. All statistical significance levels were set at .05. The results of this study follow. First, the greater the amount of physical activity among adolescents, the more positive was the effect on subjective health perception. Second, subjective body type perception had a partial mediating effect on the relationship between physical activity and subjective health perception. Third, subjective body type had a moderating effect on physical activity and subjective health perception. Specifically, people who perceived their subjective body types as average viewed their subjective health more positively when they engaged in more physical activity than those who perceived their body types as slightly or very overweight. In conclusion, preventing obesity and positively changing the subjective health status through sufficient physical activity during adolescence are important.

A questionnaire was administered to 850 middle school students in Jinju city and Hamyang province to asses their body shape preferences. Their mean current BMI(body mass index, Kg/㎡) in males(19.23±2.77) was higher than that in females(18.61±2.59). On the other hand, significant differences in BMI were not found between areas. The perceived desired weights for their current height were about+0.22kg(males) and -4.32kg(females) of their actual weights. In spite of the average weight group, many wished to lose weight because of their tendency to perceive themselves as overweight, especially among rural females. Their ideal body shape as perceived by them were 'normal' in males and 'a bit thin' in females, independent of the areas. As for the 'contentment' regarding their current weight and health, the most satisfied group in males were estimated average weight and slightly overweight group, respectively. While, the most satisfied group in females were estimated slightly underweight and overweight group, respectively. Their extreme slim-body preference might have its root in the lack of proper understanding of what the 'standard' body weight was.

Objectives: This study was performed to investigate the effects of overestimation of their own body shape on weight control behaviors, mental condition, physical activity, dietary behavior, health-related quality of life, and nutritional status among young Korean females. Methods: A total of 1,514 women aged 20-39 years who are not pregnant and lactating among those who participated in the Fifth Korea National Health and Nutrition Examination Survey (2010~2011), were analyzed and grouped into underestimation (n=120), normal estimation (NE, n=840), and overestimation (OE, n=554), based on their body perception compared to actual percent ideal body weights. Variables were compared between OE group and NE group. Results: The subjects in OE group were significantly younger (29.5 vs. 30.5 years, respectively p < 0.05) and had lower body mass index (20.9 vs. 22.2 respectively, p < 0.01), health-related quality of life measured by EQ-5D (EuroQol-5 Dimension)(0.97 vs. 0.98 respectively, p < 0.05), nutrition adequacy ratio (NAR) of protein (0.91 vs. 0.93 respectively, p < 0.05), phosphorous (0.93 vs. 0.96 respectively, p < 0.05), and iron (0.70 vs. 0.75 respectively, p < 0.01), and index of nutrition quality (INQ) of iron (0.84 vs. 0.89 respectively, p < 0.05) compared to those in the NE group. The results of logistic regression showed that unmarried status (OR 1.32; 1.01~1.72) and severely underweight/underweight status (OR 1.94; 1.01~3.75)/(OR 1.81; 1.34~2.45) were significantly related to the probability of overestimation by the subjects. Significantly more women in OE group practiced fasting, skipping meals, and taking prescribed pills to lose body weights and had skipped breakfast compared to those in the NE group. Conclusions: The results of this study suggested that the Korean young women's distorted perception of own body shape may be associated with undesirable weight control behavior, low quality of life, and lower nutritional status. Therefore, nutrition education for this group should include information on correct body shape perception and its importance.

This study compares the perceived body image of female college students in Korea and Japan as well as explains the difference in the level of self-esteem, body cathexis, body image and fashion leadership based on nationality and body. The sense of fashion leadership affected by these factors was also analyzed. A high ratio of Korean and Japanese female students perceived themselves as obese compared to actual body physique. It was shown that body was highly distorted. They showed a comparatively low level of satisfaction with appearance in contrast to their high interest in their appearance and weight. Thin bodied individuals showed a high level of self-esteem and body cathexis; however, persons with an obese body showed a low level of body cathexis. They showed high interest in appearance regardless of body physique; however, they remain unsatisfied with their appearance. Individuals with an obese body and a standard somatotype showed a high concern with weight. A high fashion opinion leadership was reciprocal to a high interest in appearance and satisfaction with appearance. Korean female students showed an indirect positive effect on fashion opinion leadership through body cathexis, self-esteem, interest in appearance, and satisfaction with appearance. A thin body showed a positive effect on fashion opinion leadership and an obese body had a negative effect. Fashion innovativeness was directly influenced persons with a high degree of self-esteem and interest in appearance. Japanese female students were directly affected by fashion innovativeness; however, Korean female students were indirectly affected by fashion innovativeness through self-esteem and interest in appearance.

he purpose of this study was to investigate the effect of body weight and body image perception on body image satisfaction of female junior high school students in Seoul. We further examined if body image satisfaction was related to obesity stress, weight control attitudes. From the 327 students surveyed, 6.1% were overweight and 38.8% of subjects were underweight. Over half of the subjects (54.4%) considered themselves to be more fat than their actual body shape. This manifested itself in low body satisfaction. Subjects less satisfied with their body shape suffered from high stress about obesity, were much more interested in weight control programs, and had more experience in weight control attempts. Among the subjects with low body image satisfaction, 25.7 % of them had eating disorder. It is our suggestion that school curriculum should include proper nutritional programmes to help students correctly recognize their body shape and to maintain healthy weight.

This study was performed to investigate body image perception and eating disorders by sex in Korean adolescents. In both females and males, the students were more likely to be underweight than overweight. Females were more underweight than males and were more likely to perceive themselves as overweight. In addition, females were less satisfied with their body shape and had more stress associated with their body weight and eating disorders. These results indicate that nutrition education programs, particularly in female students, should incorporate strategies to change inaccurate self-body image perception and disseminate knowledge about proper weight control methods.
