This study investigated the relationships between eating disorder risk, body image perception, weight control, and dietary habits in Korean women. Body shape perception, the Eating Attitude Test (EAT-26) and dietary habit information were collected by a self-administered questionnaire to 373 adult women and the data were analyzed by the Chi-square test. 31.4% of the women were classified in the eating disorder group by a score of over 20 points on the EAT-26. Compared to the normal group, more women in the eating disorder risk group perceived that a thin body shape was the ideal body shape and were dissatisfied with their body shape. This group was also more interested in weight control and more likely to try weight control methods. The eating disorder risk group was more likely to skip meals and snacks than the normal group. In addition, they had a greater appetite and a higher frequency of overeating than the normal group. Over 30% of the Korean women surveyed were categorized at high risk of eating disorders. They were more likely to overestimate body weight and shape and tried to control their weight by inappropriate methods. To prevent eating disorders in adult women, nutrition education programs should incorporate strategies to change inaccurate self-body image and to disseminate information about healthy weight control methods.
The purpose of this study was to investigate the relationships between weights of backpack and back and shoulder pains of elementary school students in Korea. A cross-sectional sample of 278 boys and 233 girls aged between 7 and 12 years were analyzed for this study. 49.1% of the participated children reported their backpacks were felt heavy, and the weights of their backpack were grater than 13.3% of their body weight. About 65.4% of students carried greater than 10% of their body weights. The weight of the backpack showed significant positive relationship with shoulder pain but not with their back pain. The results of this study suggested that overweighed backpack could cause the musculoskeletal pain to the elementary school students. Therefore, an effective backpack safety program for parents and students is necessary to educate them how to prevent possible musculosketal pain related to the weight of backpack within the perspective of the ergonomical approach.
Objective: The aim of this study was to understand the effects of phone weight on the typing performance and muscle recruitment in the neck and upper extremity while typing a text message with dominant hand. The iPhone4 and iPhone5 were compared due to their 28-gram differences in weight. Background: Too much use of a cellular phone can lead the musculoskeletal disorders in the upper extremity. Phone makers tend to make their new models bigger, lighter, faster and smarter. Method: Fourteen healthy volunteers without any history of neuromuscular disorders or ongoing pain who used their smartphone more than one year were recruited. A 112g phone (iPhone5) and a 142g phone (iPhone4) were used for typing the lyric of the Korean national anthem with their dominant hand. Typing duration, the typing error, the perceived fatigue, and preference was investigated. Muscle recruitment and the resting gap of neck (middle trapezius and levator scapula), shoulder (infraspinatus and mid deltoid), elbow (biceps brachii and brachioradialis), thumb (extensor and abductor policis brevis) were collected using surface electromyography. Typing error was counted and typing speed was calculated in characters per min. The data were analyzed using a paired t-test and chi-square (${\chi}^2$) analysis for the effects of phone weight on the typing performance parameters and muscle recruitment. Results: Typing text message with iPhone5 took longer but had less muscle recruitment in brachioradialis, and extensor policis brevis muscles. Lighter weight of iPhone5 made biceps brachii to rest less without increasing the mean %EMG. Conclusion/Application: Findings of this study can be valuable information for phone designers to develop more productive device and for smartphone users to prevent the musculoskeletal disorders in the upper extremities.
This study aimed to find out the relationship between the body shape and the degree of obesity and the eating attitude influenced by the eating disorder among male and female college students. Followings are the summary of the results obtained in this study : 1. Male students perceived their own body shape properly, however female students perceived their body shape fatter than their real one even if almost all of them were maintaining normal weight. 2. For both male and female students the EAT-26 score was high when they perceived themselves fat, and in the group of students perceiving themselves fat the F I score was high and the F III score was low. Contray to this, in the group of students perceiving themselves thin the F nt score was high. The EAT-26 of female students marked higher than that of males in total questionares. 3. The EAT-26 score was high for both male and female students whose degree of obesity was high. The higher the degree of obesity the higher the F I score, and the lower the degree of obesity the higher the F III score. 4. For both male and female students the dieting frequency was high when they were in the group perceiving themselves fat and in the group with the high degree of obesity. And the number of females' is higher than that of males'. For male students there was no significant difference of dieting frequency in accordance with the perceived body shape and the degree of obesity. However, for female students the frequency was high when they were in the group perceiving themselves fat and in the group with the high degree of obesity. The frequency was high when they were in the group perceiving themselves thin and in the group with the low degree of obesity. 5. For the matter of relationship between the degree of obesity and the frequency of buying meals there was significant difference only in the female students and the frequency of buying meals was higher when the degree of obesity was higher.

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.
Objectives: In this study, perception of body image, eating attitudes and weight control were examined by the degree of obesity using Body Mass Index (BMI). Methods: Out of 420 questionnaires distributed to the female middle school students (aged 12-16 years), 407 were returned (97% response rate) and 395 were analyzed (94% analysis rate). Female students were divided into two groups based on the BMI percentile using the 2007 Korean National Growth Charts. (1) normal weight ($5^{th}$ percentile ${\leq}$ BMI < $85^{th}$ percentile) (2) obese ($85^{th}$ percentile ${\leq}$ BMI) by 2007 Korean National Growth Charts. Satisfaction of self-body shape, risk of disturbed eating attitudes (Eating Attitude Test : EAT-26), and weight control behaviors were examined. Results: Distribution of the subjects by BMI was 74.5% of normal and 25.5% of obese. There were significant differences between self-perceived current body image and self-perceived ideal body image. The dissatisfaction of body image was higher in obese than in normal groups (p<0.001). 51.4% of female students were unsatisfied with their body image, while 2.6% were very satisfied. Among the students unsatisfied with their body image, 150 (52.1%) were of normal weight and 48 (49.4%) were obese. EAT-26 total scores were significantly higher in the obese group ($16.42{\pm}8.23$) compared with normal group ($13.72{\pm}8.10$) (p<0.01). Attempted to weight control were significantly different by the BMI (p<0.001). Conclusions: This study concludes that there was desire to become thinner than current status in female students, even those with normal BMI. Many female students were dissatisfied with their body image and attempted to lose weight. It is harmful to their health and nutritional status if they choose undesirable methods. These findings suggested that there are needs to encourage female students for maintaining healthy weight. A higher score of EAT-26 was associated with dissatisfaction of selfbody image and this may lead to unhealthy behaviors in obese female students.
BACKGROUND/OBJECTIVES: This study aimed to examine differences in weight control practices, beliefs, self-efficacy, and eating behaviors of weight class athletes according to weight control level. SUBJECTS/METHODS: Subjects were weight class athletes from colleges in Gyeong-gi Province. Subjects (n = 182) responded to a questionnaire assessing study variables by self-report, and data on 151 athletes were used for statistical analysis. Subjects were categorized into High vs. Normal Weight Loss (HWL, NWL) groups depending on weight control level. Data were analyzed using t-test, ANCOVA, x2-test, and multiple logistic regressions. RESULTS: Seventy-three percent of subjects were in the HWL group. The two groups showed significant differences in weight control practices such as frequency (P < 0.01), duration and magnitude of weight loss, methods, and satisfaction with weight control (P < 0.001). Multiple logistic regression showed that self-efficacy (OR: 0.846, 95% CI: 0.730, 0.980), eating behaviors during training period (OR: 1.285, 95% CI: 1.112, 1.485), and eating behaviors during the weight control period (OR: 0.731, 95% CI: 0.620, 0.863) were associated with weight control level. Compared to NWL athletes, HWL athletes agreed more strongly on the disadvantages of rapid weight loss (P < 0.05 - P < 0.01), perceived less confidence in controlling overeating after matches (P < 0.001), and making weight within their weight class (P < 0.05). HWL athletes showed more inappropriate eating behaviors than NWL athletes, especially during the weight control period (P < 0.05 - P < 0.001). CONCLUSIONS: Self-efficacy was lower and eating behaviors during pre-competition period were more inadequate in HWL athletes. Education programs should include strategies to help athletes apply appropriate methods for weight control, increase self-efficacy, and adopt desirable eating behaviors.
Purpose: This study was carried out to find factors affecting weight-control behavior intention in female college students based on the theory of planned behavior. Methods: The subjects were 453 female students from everywhere other than the Gangwon Province and Jeju Island. Data were collected by using a questionnaire. Results: The factors affecting weight-control behavior intention in female college students within 2 weeks were attitudes and subjective norms. These two factors accounted for 20.0% of weight-control behavior intention. Also, when body shape satisfaction and BMI were added to variables of the theory of planned behavior like attitudes, subjective norms, and perceived behavior control, these 5 factors accounted for a total of 34.1%. Conclusion: Due to their distorted perception in preferring skinny body shapes, female college students are likely to attempt at inappropriate weight control behavior. Through intervention with such factors as attitudes and body image satisfaction, which have been derived from the results of this study, healthy weight control behavior should be pursued in practice.

Purpose: The purpose of this study was to investigate perceived family support and quality of life in patients with cancer. Method: Data were collected from 83 cancer patients in the 3 cities of Korea. Family support was measured using the Tae's Family Support Scale and quality of life was measured using Functional Assessment of Cancer Therapy-General (FACT-G). Results: The mean scores of family support and quality of life were 30.48 and 53.04 respectively. Family support was significantly different according to marital status, education level, income, living together, helper, type of treatment, and weight change. Quality of life was significantly different according to the purpose of treatment, weight change, performance status, exercise, and sleep. There was a positive correlation between family support and quality of life (r=0.499, p<0.000). Conclusion: The study results underscore the importance of family support in improving the quality of life of patients with cancer.

Purpose: The purpose of this study was to examine the effects of exercise intervention, including dumbbell(weight lifting), walking, and yoga, on the body composition, physiologic factors, body image, and perceived health in the community-dwelling women. Method: This study utilized pretest-posttest design with three types of exercise interventions. The types of exercise intervention included dumbbell, walking, and yoga. Results: A total of 136 subjects were included: 49 for dumbbell, 67 for walking, and 20 for yoga. As measures of body composition, BMI, body weight, and body fat rate were significantly improved only after dumbbell intervention(p<.01). Systolic blood pressures were significantly decreased in the groups of dumbbell and walking. Diastolic blood pressure was significantly declined only in the walking group. Vital capacities and body image were improved in all groups(p<.01). However, total cholesterol levels were not improved in all groups(p>.05) and none of the measures for perceived health state were not significantly changed in all groups(p>.05). Conclusion: From the findings of this study, it was demonstrated that the effects of exercise interventions were differentiated by their types and variables to be affected. Therefore, future studies that apply the tailored exercise intervention to each age-categorical group are needed.
