Objectives: The study aims to determine whether there is an association of perceived weight status with unhealthy diet practices. Method: An analytic cross-sectional study was conducted among 625 adult undergraduate students from U.P. Manila. The survey included questions regarding sociodemographic status, habits related to diet and weight management, and perceived body mass index (BMI). Actual BMI were obtained and calculated from actual anthropomorphic measurements. Results: In the population surveyed, it was seen that 53.28% of the students accurately perceived their BMI status, 26.08% overestimated their BMI status, while 17.28% underestimated their BMI status. It was also seen that over-estimating of BMI status is more associated with unhealthy diet practices. Those who over estimated their BMI were 1.95 times more likely to skip meals (p=0.001) and 1.56 times more likely to engage in cutting of food (p=0.034). Physical activity was also seen to be associated with these practices. Conclusion Over-estimation of BMI may be linked to unrealistic goals in weight loss resulting in unhealthier diet-related habits.

OBJECTIVES: Misperception of weight status is a risk factor that affects psychological health. The aim of this study was to evaluate the association between weight misperception patterns and psychological distress among Iranian children and adolescents. METHODS: This was a cross-sectional nationwide study where data was collected from 14,440 students, aged 7–18 years who participated in the national school-based surveillance program (CASPIAN-V). The students’ weight perception and psychological distress were assessed by validated questionnaires. Weight misperception was classified as misperception of being either underweight or overweight with respect to actual weight. RESULTS: The rate of weight misperception in all study participants was 59.1%. In groups with a perception of being underweight or overweight, the risks of worthlessness, being worried, experiencing aggression, insomnia, or depression, were significantly higher than groups with an accurate weight perception (p < 0.05). The risk of anxiety in girls of normal weight who perceived themselves as underweight, decreased by 57% compared to girls with an accurate weight perception (OR: 0.43; 95% CI, 0.28–0.66). CONCLUSION: Weight misperception is highly prevalent among Iranian children and adolescents and is associated with their psychological health status. Appropriate education intervention needs to be developed to improve the children and adolescents’ perception of their body weight status.

PURPOSE: This study was performed to elucidate whether the obesity or body image is a barrier to breast screening compliance in Korean women. METHODS: We included 54,017 women aged between 35 to 70 years from the Korea Community Health Survey (KCHS) 2014 dataset. To identify whether a mutual relationship exists between weight perceptions and breast cancer screening rates, the participants were divided into three groups according to the level of concordance between Body Mass Index (BMI) and a subjective body image. Descriptive analyses, a chi-square test, and multivariate logistic regression analyses were performed. RESULTS: After covariate adjustment, the screening rate of the overweight group was 1.09 times higher than the normal weight group (odds ratio [OR], 1.09; confidence interval [CI], 0.00–0.16; p=.038) and the severe obesity group was 1.20 times lower (OR, 0.83; CI, −0.36–0.00; p=.047). Weight misperception also had a significant influence on breast cancer screening. Especially, The overweight distortion group was less likely to undergo breast cancer screening (OR, 0.93; CI, −0.15–0.00; p=.037). CONCLUSION: Obesity and weight misperceptions are associated with lower compliance with breast cancer screening guidelines.

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/m²) 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/m²), 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.

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: 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: This study aimed at identifying the current nutrition knowledge, body-related perspectives, and weight control behaviors of Korean-Chinese college students. METHODS: We conducted a pilot study by employing a healthy weight education program targeting Korean-Chinese nursing school students at the Yanbian University of Science and Technology in Yanbian, China. RESULTS: This pilot study included 40 participants (38 women and 2 men; mean age, 20.5 years). The current weight status of the participants was as follows: 7.9% underweight, 78.9% normal weight, 7.9% overweight, and 5.3% obese. However, nearly two-thirds of the participants were dissatisfied with their current body size (43.6% a little dissatisfied; 20.5% very dissatisfied). Fifty percent of the participants perceived their current body size as being either slightly fat (35.0%) or very fat (15.0%). The following unhealthy weight control methods were commonly used among the 24 participants who practiced weight control: (1) laxatives or diuretics (91.7%), (2) saunas or spas (87.5%), and (3) a one-food diet (79.2%). In addition, the nutrition knowledge of the participants increased by 24 points from 117 points (pretest) to 141 points (posttest) through the healthy weight education program. CONCLUSION: The findings of this study indicate an urgent need to educate Korean-Chinese college students on healthy weight control methods and body-related perspectives.

PURPOSE: This study was done to investigate the prevalence and factors affecting body shape misperception among Korean adult women. METHODS: We analyzed raw data from the fourth Korean Longitudinal Survey of Women and Families, for 7,658 women over 20 years of age. For the multiple logistic regression model, the dependent variable was existence of misperception (yes/no). RESULTS: The prevalence of body shape misperception was 42.6% (overestimation 6.5%, underestimation 36.1%). Multiple logistic regression analysis revealed that age, education level, marital status, economic status and BMI were significantly associated with body shape underestimation. Education level and BMI were significantly associated with body shape overestimation. CONCLUSION: An effective obesity intervention program for women must reflect and monitor body shape perception as well as BMI.

Suicide is a leading cause of death among adolescents globally, and body weight is also a recognized reason for adolescent suicide. Therefore, we investigated the association between weight control behaviors (WCB) and suicide ideation and attempt, focusing on inappropriate weight control measures. We used data from the 2014 Korea Youth Risk Behavior Web-based Survey, representing a total of 35,224 boys and 34,361 girls aged 12 to 18 years. Adolescents were classified into groups based on WCB: appropriate WCB, inappropriate WCB, and no WCB. We performed logistic regression models to examine associations between WCB and suicide ideation and attempt, controlling for covariates. Both boys and girls with inappropriate WCB were more likely to report suicide ideation and attempt. Underweight and normal weight boys with inappropriate WCB were more likely to think or attempt suicide, and underweight girls with inappropriate WCB were also more likely to attempt suicide. Among five common WCB combinations, the combination of "regular exercise, fasting, eating less" was highly associated with suicide ideation and attempt. We confirmed that inappropriate WCB is associated with suicide ideation and attempt among Korean adolescents. Given the high incidence rate of suicide among adolescents and the adverse effect of inappropriate WCB, encouraging adolescents to control their weight in healthy ways is imperative.

OBJECTIVES: Describe health beliefs of pregnant women with diabetes using tweets. Describe how information on diabetes in pregnancy is shared on Twitter.

METHODS: Tweets by women with diabetes were identified from Symplur Signals. "Status" tweets were mapped to the Health Belief Model. Tweets by women with preexisting diabetes and gestational diabetes (GD) were analyzed separately. Links within tweets were surveyed for the Health on the Net (HON) Foundation seal.

RESULTS: Women with GD tweeted about cravings and the connection of high carbohydrate meals with big babies. Perceived barriers included food restriction, hunger, lab tests, clinic consults and blood glucose monitoring. Perceived benefits of blood glucose testing and a healthy diet were linked to healthy babies. Blood glucose monitoring, weight gain, and age of gestation were cues to action. Perceived barriers of women with preexisting diabetes were feelings of helplessness, loss of control, and anger. Nine domains (9.7%) had the HON Code seal. Women with preexisting diabetes shared blog posts. Women with GD shared links from organizations.

CONCLUSION: Women with GD and preexisting diabetes had differing perceptions of susceptibility, severity, barriers, benefits, cues to action, and self-efficacy; and shared links to information differently on Twitter.
