The purpose of this study was to examine the factors affecting subjective body shape perception among female university students. This research conducted a survey targeting 121 female university students. The collected data were analyzed by Pearson's Correlation, Multiple Regression using SPSS/Win 23.0. were identified as factors influencing on subjective body shape perception in female university students. As the results of regression analysis, sociocultural attitudes towards appearance, body cathexis, self-esteem, BMI demonstrated significant effects on subjective body shape perception. and these are significantly predicted 46.8% of subjective body shape perception. The factor of the greatest impact on subjective body shape perception is sociocultural attitudes towards appearance. In order to positively change body shape perception, it is necessary to help them perceive their body shape as it is, accept the actual body shape, and have a specific way to be satisfied with their body shape.

This study was conducted to establish the effects of subjective body-forming perception on weight-controlling behavior and weight loss, and to suggest the need for proper information and education. Using the data from the National Health and Nutrition Examination Survey conducted in the 6th period (2013-2015), 6,238 women aged 19 and over who have a body mass index of $18.5-25kg/m^2$ were analyzed. As a result, the higher the level of education and income level, the higher they were perceived to be obese, the more they chose to lose exercise and diet in order to lose weight across the board. The weight loss effort rate was higher in the obese body type recognition group, but the body weight type was the highest in the one year body weight change group (p < .001). As a result, subjective perception of body shape affected not only weight control behavior but also weight change (p < .001). Accordingly, it is necessary to have a systematic education on healthy weight-controlling behaviors, proper body image, and healthy body type recognition.

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.

The purpose of this study was to examine the relationship of body-shape perception and periodontal diseases in female adolescents based on the sixth 3rd-year(2015) data of the National Health and Nutrition Examination Survey. The subjects in this study were 211 female teenagers who were at the western ages of 12 to 18. As a result of analyzing, it's found that the body-shape perception of the female teens were linked to age, sleep hours, BMI, weight control and toothbrushing frequency, and whether they had periodontal diseases or not was found to be under the influence of age, smoking, sleep hours, stress, BMI and toothbrushing frequency. When the relationship between their body-shape perception and peridontal diseases was analyzed by controlling the confounders, the adolescents who considered their own bodies to be obese suffered from 3.18-fold more periodontal diseases(OR=3.18, 95% CI: 1.21, 8.38) than the teenagers who considered their body shape to be average. In the future, oral health care should be provided in consideration of the mental health of female adolescents to prevent periodontal diseases.

This study examined the relationships among body perception, anxiety, psychological flexibility, and abnormal eating habits of college students. Data was collected through a self reported structured questionnaire from 289 Korean college students using convenient sampling methods from April 20 to June 30, 2013. Multiple linear regression revealed the subjective body perception (${\beta}$=0.28, p<.001), ideal body image (${\beta}$=-0.15, p=.004), anxiety (${\beta}$=0.21, p<.001), and psychological flexibility (${\beta}$=-0.13, p=.032) to be significant predictors of abnormal eating habits of college students. These variables accounted for 26% of abnormal eating habits (F=17.42, p<.001). Therefore, as a strategy for reducing abnormal eating habits, therapeutic nursing intervention will be needed to improve the psychological flexibility and control anxiety as well as correct the distorted body perception.

This study was conducted to compare the factors affecting quality of life according to the perception of subjective body image in adult women as a secondary study of the 7th 1st year Korean National Health and Nutrition Examination Survey data. The subjects were 3,392 adult women and their general characteristics, physical factors and psychological factors were analyzed. Data were analyzed using the IBM SPSS 25.0 program after generating weighted composite sample plans and the significance level was set at 0.05. Factors influencing the quality of life of subjects who perceived their subjective body image as thin were education level, birth experience, depression, and subjective health and their explanatory power was 43.1%. Factors influencing the quality of life for those who perceived their bodies as moderate were education level, depression, and subjective health, and their explanatory power was 26.5%. Factors that affected quality of life for those who perceive their bodies as obese were age, weight change for one year, weight control for one year, presence of high blood pressure, BMI, and subjective health, and their explanatory power was 40.9%. The results of this study indicate it is necessary consider the factors influencing each subjective perception to improve individual quality of life.

The objective of this study was to investigate the effects of the subjective perception to the nutrient intake and mental health of Korean adolescents by the residual method. This study was based on data from the 5th and 6th Korea National Health and Nutrition Examination Survey (2010-2014) of the 2,961 total subjects(male 1,548, female 1,413, aged 12 to 19 years). The nutrient intake was collected by using the 24 hr recall method and mental health and BMI were collected by the health interview survey and physical examination research. An analysis of the relationship between the subjective perception and BMI showed that the proportion of those with a distorted perception of their body type was the highest among adolescents with normal weight(p for trend, <.001). Especially, regarding the subjective body type, the proportion of adolescents who perceived themselves overweight was significantly higher among females as compared to that among males (p for trend, <.001). An analysis of nutrient intake status against the subjective perception showed that the group of adolescents who perceived themselves overweight had the lowest scores on the index of nutritional quality (INQ), nutritional adequacy ratio (NAR) and mean adequacy ratio (MAR) (p for trend, <.001). With respect to the daily intake of major nutrients, adolescents who perceived themselves overweight consumed the lowest amounts of total energy (p for trend, <.01) and carbohydrate (p for trend,<.001). An analysis of the mental health status of the adolescents showed that those who perceived themselves overweight had the highest levels of stress recognition and depression (p<0.01). In conclusion, the adolescents' subjective perception is associated with their nutrient intake and mental health. Therefore, some educational programs are desirable to help the adolescents to have their desirable subjective perception and to increase their satisfaction with their body type.

The aim of this study was to determine the association between the Body Mass Index (BMI), weight perception and depression-like symptoms in Korean middle school students. The data was obtained from the 2012 Korea Youth Risk Behavior Web-based Survey. The subjects were 37,297 students living in the community. Adjusting for covariates (sex, school year, home economics, city-type, school record, self-reported happiness, self-reported health status, suicidal thinking, smoking, alcohol consumption), the self-reported obesity (OR=1.14, 95% CI: 1.06-1.22) and self-reported underweight (OR=1.11, 95% CI: 1.03-1.20), compared to the self-reported healthy weight, were more likely to have depression-like symptoms. On the other hand, the BMI-based weight was not associated independently with depression-like symptoms. These findings suggest that weight perception is significantly associated with depression-like symptoms.

The purpose of this study was to investigate the relationship between age, physical activity (walking, strength exercise), subjective body shape recognition, and weight change with subjective health status in the population aged 30 years or older among the data of the National Health and Nutrition Examination Survey (2018) of Koreans. The subject and method of this study was a secondary analysis study using the 7th 3rd year National Health and Nutrition Examination Survey (2018). Age, walking days per week, strength training days per week, subjective health status, subjective body shape recognition, and weight change during the year were used the SPSS (p<.01). The response rate of walking for 7 days (every day) was 21.9% for those aged 30-45, 27.2% for those aged 50-64, and 26.6% for those aged 65 or older. aged 8.4% and over 65 years old 7.9% (p<.001). The subjective health status was positively correlated with age (.091), number of walking days per week (.739), number of days of strength exercise per week (.530), subjective perception of body shape (.256), and weight change over one year (.303). There was a relationship (p<.01). In this study, the age group that answered 'bad' in subjective health status was the highest at 21.4% of those aged 65 or older, followed by 15.7% of those aged 50-64 and 11.0% of those aged 30-45. This could be expected to improve subjective health status by walking and strength training. Based on these results, it was intended to provide basic data for preparing health-related programs to improve subjective health status of individuals according to age.
