Purpose: This study aims to investigate gender differences in the association between depressive symptoms and weight, weight perception, and body satisfaction among Korean adolescents. Methods: A secondary data analysis was performed on data from 33,374 adolescents who participated in the 2015 Adolescent Health Behavior Online Survey. They were classified as underweight, normal weight, or overweight/obese; weight perception was classified into perception of being underweight, normal weight, or overweight/obese; and weight satisfaction into desire to gain weight, satisfied, and desire to lose weight. Results: Among boys, perception of being underweight (adjusted odds ratio [AOR]: 1.20, 95% confidence interval [CI]: 1.07~1.35) and desire to gain weight (AOR: 1.45, 95% CI: 1.30~1.62) were associated with depression. Among girls, perception of being overweight or obese (AOR: 1.18, 95% CI: 1.07~1.29) and a desire to lose weight (AOR: 1.30, 95% CI: 1.18~1.42) were associated with depression. Conclusion: Gender differences were observed in the association between weight perception and depression in adolescents. The perception of being underweight among boys and the perception of being overweight/overweight among girls were associated with depression. Thus, gender-specific intervention programs to correct weight perception and weight satisfaction are needed in order to relieve depressive symptoms in adolescents.

Purpose: Women's weight perception and obesity-related quality of life were analyzed according to BMI (Body Mass Index). Methods: A survey was conducted using self-report questionnaires from 178 participants. The data analysis included descriptive statistics, frequency, percentage, t-test, ANOVA, Fisher's exact test and Kendall's tau using the SPSS version 14.0. Results: There were significant differences in BMI according to age (F=8.037, p=<.001), weight perception (F=60.71, p<.001), weight control experience (F=2.504, p=.013), weight control method (F=5.839, p=.001) and weight control success (F=-2.451, p=.016). There was a significant difference in obesity-related quality of life according to weight perception in the low weight group (F=5.587, p=.021) and in the obesity group (t=3.419, p=.003). Higher correlations were found between the women's BMI group, weight perception and obesity-related quality of life. Conclusion: A program to provide appropriate information for weight perception is needed for the low weight group. There is a need for a program about weight reduction as well as weight perception for the obesity group.

Purpose: The present study is focused on understanding weight perception related with individual- and school-level multifactorial origins, underestimated and overestimated respectively, in normal body weight adolescents. Methods: Using the 2017 Korea Youth Risk Behavior Web-based Survey data of 45,902 students from 799 secondary schools, a multilevel multinomial logistic regression analysis was performed where adolescents (level1) were nested within schools (level 2). Results: At the school level, the average school body mass index (BMI, $kg/m^2$) and physical education were associated with weight perception among both boys and girls. In boys, geographic areas were associated with weight underestimation. At the individual level, perceived economic status, weekly allowance, BMI ($kg/m^2$), smartphone usage time (hrs/day) and perceived stress were associated with weight perception among both boys and girls. Age, paternal education, academic achievement and alcohol use were associated with weight perception among girls, while part-time job and physical activity were associated with weight perception among boys. Conclusion: Our findings underscore the importance of individual- and school-level environments in developing correct weight perception and have implications for school health education to establish healthy lifestyle behaviors for all adolescents.

Background: Body image is associated with the perception of people on themselves. Influencing factors are generated internally and/or externally. The most common issue pertaining to body image is body weight and weight loss. This study aimed to determine the association between body weight perception and weight loss practices among college students. Methods: A cross-sectional study was conducted involving 297 college students from private nursing colleges in the state of Kelantan, Malaysia. A self-administered questionnaire was used to assess sociodemographic characteristics, body weight perception, and weight loss methods. Weight and height were measured, and body mass index (BMI) was calculated based on weight and height measurement. The World Health Organization BMI cutoffs were applied in the study. Results: More than half (54.2%) of college students perceived their weight correctly as per actual measured BMI. A total of 51.5% of participants had tried various methods to reduce their weight. Body weight perception is associated with weight loss practices (odds ratio, 0.31; 95% confidence interval, 0.19-0.50; P<0.001) adjusted for sex, marital status, and status of having obese family members. Those who had correct body weight perception were less likely to engage in weight loss practice. Food intake restriction (42.4%) is the most popular weight reduction method among students in nursing colleges. Over a quarter of the participants chose physical exercise (25.3%) to reduce their weight, and a small number engaged in unhealthy weight loss practices. Conclusion: Body weight perception is an important factor that influences the practice to reduce weight especially among young adult group and college students.

Purpose: The aim of this study was to assess the body weight perception of adolescents and to investigate the difference between mental health and weight control behavior according to body weight perception. Methods: Study data on 12-18 years old adolescents with normal BMI was obtained from the 6th Korea National Health and Nutrition Examination Survey (2013-2015). Rao-Scott Chi-square test and ANOVA were used for the analysis. Results: The percentage of adolescents with a misperception of body weight was 43.3%, and their subjective health status (p=.013), stress perception (p=.001), and depression (p=.001) were worse than for adolescents who had the correct perception of their body weight. The percentage of adolescents who were trying to lose weight while perceiving their body weight as normal was 36.9%. Body weight control behavior had significant differences according to dietary intake (frequency of eating dinner (p=.015)), energy intake (p=.004), and carbohydrate intake (p<.001), but there was no significant difference according to exercise. Conclusion: Parents, school teachers, and nurses should make efforts to ensure that Korean adolescents perceive their body weight correctly, and prevent unhealthy weight control behaviors.

Objectives: The purpose of this study was to assess the characteristics of body weight perception and physiological index in young adult women. Methods: Subjects were 283 Korea women. Data was from the 2005 Korean National Health and Survey. Three groups-low normal and overweight-were based on Body mass index(BMI). General characteristics, health status perception, weight control behavior and physiological index such as BMI, total cholesterol, high-density cholesterol (HDL), low-density cholesterol (LDL), triglyceride, systolic and diastolic blood pressure, and waist circumference were compared. Data were analyzed by t-test, $x^2$-test and ANOVA using SPSS program. Results: Of the normal weight group, 28.7% of subjects perceived themselves as overweight. Of the low weight group, 30.3% regarded their weight as normal weight. Of the overweight subjects, weight control was attempted by exercise (50.1%) and food reduction (77.1%). Significant group-related differences were evident in HDL, LDL, triglyceride, systolic blood pressure and waist circumference among three groups. Conclusions: Perception and attitude regarding body weight can be inaccurate. A weight control program should consider the relation of physiological index and weight based on BMI.

Virtual object weight perception is an important topic, as it heightens the believability of object manipulation in immersive virtual environments. Although weight perception can be achieved using haptic interfaces, their technical complexity makes them difficult to apply in immersive virtual environments. In this study, we present a visual pseudo-haptic feedback system that simulates and depicts the weights of virtual objects, the effect of which is weight perception. The proposed method recognizes grasping and manipulating hand motions using computer vision-based tracking methods, visualizing a Force Arrow to indicate the current lifting forces and its difference from the standard lifting force. With the proposed Force Arrow method, a user can more accurately perceive the logical and unidirectional weight and therefore control the force used to lift a virtual object. In this paper, we investigate the potential of the proposed method in discriminating between different weights of virtual objects.

Purpose: To compare differences in BMI, body weight perception and satisfaction, and eating behavior by gender among middle school students. Methods: From 19 middle schools in W city four classes in two middle schools were selected by cluster sampling with multi-stage sampling. A structured questionnaire was answered by 143 adolescents. Results: Differences in BMI between boys and girls were significant (x$^2$=13.15, p=.00l). Boys reported higher ideal body weight than girls (t=6.33, p<.000l), and discrepancy between ideal body weight and body weight perception in girls was significantly greater than in boys(t=-5.0l, p<.0001). There was no significant gender difference in body weight perception but more boys were satisfied with their body weight(t=-4.48, p<.0001). Comparison of eating behavior showed that girls reported high scores in disinhibition (t=-2.29, p<.05) and hunger (t=-2.81, p<.01), while boys reported higher scores in cognitive restraints (t=3.22, p<.01). Conclusion: Interventions to help girls improve body image and satisfaction with body image are crucial. In order to establish proper diet habits and balanced nutritional status for adolescents, educational interventions should address characteristics of eating behaviors.

Objectives: We examined the relationships between the body mass index, body weight perception, and depressed mood in a nationally representative sample of Korean adolescents. Methods: We analyzed the data from the 2013 Korean Youth Risk Behavior Web-based Survey and evaluated the relationships between the body mass index, body weight perception, and depressed mood by gender (36655 boys and 35780 girls). Results: For boys, a low body mass index and perceiving oneself as underweight were related to depressed mood. For girls, both low and high body mass indices were negatively related to depressed mood. In addition, self-perceptions of being underweight or overweight were positively related to depressed mood. Body weight perception was not a significant mediator in the relationship between body mass index and depressed mood. Conclusion: These results suggest that both body mass index and body weight perception significantly contribute to Korean adolescents' depressed mood. Thus, research and clinical attention needs to be given to underweight as well as overweight adolescents, because those who perceive their weight as not normal are at risk for depression.
