Objective: In clinical practice, there are a lot of exercise to reduce body weight or reduce the amount of body fat in order to solve back pain. However, many studies have contradicted the relationship between back pain and weight or body fat mass. The purpose of this study was to investigate the relationship between fat mass, body mass index and low back pain of office worker. Design: Crossed-sectional study Methods: Among the white-collar workers diagnosed with non-specific back pain by doctors, subjects who were not included in the exclusion criteria were selected to measure the subject's body fat mass, body mass index, pain intensity, and disability index due to back pain. The NPRS was used for the intensity of back pain of office workers, and the ODI was used for the degree of disability due to back pain. A body composition analyzer was used to measure the body fat mass and body mass index of white-collar workers. Results: There was no significant difference between the two groups in the comparison between the normal group and the excessive group according to the criteria of fat mass and body mass index. In the correlation analysis of fat mass, body mass index, pain intensity, and disability index, it was found that there was a significant correlation between fat mass and body mass index. However, neither fat mass nor body mass index had a significant correlation with pain intensity and disability index. Conclusions: The fat mass and body mass index of office worker do not affect low back pain.

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.

Background: The rising prevalence of asthma may be associated with the rising prevalence of obesity in developed nations. There are several studies showing that obesity increases the risk of asthma in adults. We investigated the association of each body composition scale and bronchial hyper-responsiveness. Methods: This study involved a retrospective review of the existing records for 279 subjects with respiratory symptoms, who underwent a pulmonary function test, a methacholine challenge test and a body composition test between May 2007 and June 2009. Results: Of the 279 subjects, 179 (64%) were female. There was a statistically significant difference in fat free mass and in fat free mass index between the normal bronchial responsiveness group and bronchial hyper-responsiveness group (p=0.036; p=0.000). There was no significant differences in body mass index, in fat mass and fat free mass index in the normal bronchial responsiveness group and bronchial hyper-responsiveness group in males. However in females, body mass index and fat free mass index were increased in the bronchial hyper-responsiveness group (p=0.044; p=0.000). Total body water (kg), fat free mass (kg) and soft lean mass (kg) were significantly different between the normal bronchial responsiveness group and bronchial hyper-responsiveness group (p=0.002; p=0.000; p=0.000). Conclusion: This study showed significant differences in fat free mass and in fat free mass index between the normal bronchial responsiveness group and the bronchial hyper-responsiveness group. In females, BMI, soft lean mass, and total body water showed significant differences between the normal bronchial responsiveness group and the bronchial hyper-responsiveness group. We concluded that bronchial hyper-responsiveness was associated with not only body mass index but also fat free mass index in female bronchial asthma.

Background: Recently obesity has become a social problem in all over the world including Korea. It is known that obesity is closely related with cardiovascular disease. Many studies are carrying out in the relation between several obesity indices, such as body mass index(BMI), waist-circumference(WC), body fat percent and risk factors of cardiovascular disease. Objective: This study was done in order to investigate correlation of obesity and cardiovascular risk factors. Method: We gathered totally 138 subjects who have taken health screening test in university hospital. With the exception of 40 abnormal cases on current illness and laboratory study, 98 healthy cases were analysed. We divided the groups as normal, overweight, obese group according to body mass index $(22.9kg/m^2\;and\;below\;/\;23{\sim}24.9kg/m^2\;/\;25kg/m^2\;and\;above)$and investigated the relationship between obesity based on body mass index(BMI) and cardiovascular risk factors. And investigated the relationship between each cardiovascular risk factor and body mass index, waist-hip ratio, body fat percent. Results: With the exception of blood pressure, other lab data such as total cholesterol, triglycerid, glucose were significantly different between the three groups divided by body mass index$(22.9kg/m^2\;and\;below\;/\;23{\sim}24.9kg/m^2\;/\;25kg/m^2\;and\;above)$. And Correlation coefficient of cardiovascular risk factors with body mass index, waist-hip ratio, body fat precent were acquired. Conclusion: We have concluded that the body mass index and waist-hip ratio body fat precent were predictive factors cardiovascular disease.

This study was performed to examine the relationship between the body mass index (BMI), the body fat, and the serum lipids of post-menopausal women in rural areas. The subjects were 510 women aged 50 and over. As a result of this study, we found a trend of decreasing BMI as age increased, but body fat increased. In addition, there was a significant decreasing of the lean body mass than an increasing of the body mass index according to increasing age. Therefore, this study confirmed that a main cause of rural women being classified as obese is a decrease in lean body mass, rather than an increase in of body fat. Of all subjects, 36.3% ($18.5{\leq}BMI$ < 23) of all subjects were classified as having normal BMI, whereas only 21.4% were classified as having normal body fat. Out of 190 subjects who were body fat 30% and over, 38 subjects were classified as obese ($BMI{\geq}25$) and 113 subjects were classified as overweight ($23{\leq}BMI$ < 25). The percentile of those with a BMI of $25kg/m^2$ was 70, and they had 30.82% body fat. HDL cholesterol showed a negative correlation with anthropometric factors (height, weight, body mass index, waist circumference, waist hip ratio, body fat), and total cholesterol, LDL cholesterol, and triglycerides showed a positive correlation. Especially, total cholesterol, LDL cholesterol, and hip circumference showed significant correlations. Because of differences in the body fat and lean body mass by age group, it seems difficult to assess obesity via BMI only. The elderly especially should have a higher significance placed on body fat or abdominal fat than only BMI.

Purpose: This study aims to discover the relation between the sleep duration and quality of adolescents and their body mass index. Methods: The study used data obtained through the 2009 online survey on adolescents health behaviors, targeting a total of 75,066 middle and high school students (39,612 of male students and 35,454 of female students). We first performed t-test, ANOVA and Scheffe's test and then the potential variables which was possibly related to the body mass index are determined from the tests. Using the potential variable, we performed the multiple regression analysis to finally identify the relation between the duration and quality of sleep. Results: As a result, the 39.8% of male students and the 46.5% of female students most frequently respond that the sleep duration was less than 6 hours, and 36.4% of male students and the 45.3% of female students respond that the quality of sleep was not good enough. The body mass index of both the male and the female students portionally decreases to their sleep duration, but the better quality of sleep makes their body mass index higher. Conclusion: In conclusion, the body mass index has some notable relationship with the sleep duration and quality for adolescents. It is advised to consider the sleep duration and quality in the business plans for adolescents in order for the prevention of their body mass index.

PURPOSE : The purpose of this study was to determine whether tredmill exercise increases pulmonary function and decreases body mass index of the 20s obesity. METHOD : Thirty obesity in their 20s were randomly assigned to on experimental group (n=15) or control group (n=15). Over the course of four weeks, the experimental group participated in tredmill exercise for 30 minutes three times per week and the control group participated in auto-med exercise for 30 minutes three times per week. Subjects were assessed pre-test and post-test by measurement of pulmonary function (tidal volume, inspiration reserve volume, expiratory reserve volume, vital capacity) and body mass index. RESULT : Our findings show that the experimental group had significant difference in expiratory reserve volume and vital capacity and body mass index (p<.05). In the comparison of the two groups, the experimental group had higher pulmonary function and lower body mass index than the control group. CONCLUSION : In this study, the experimental group showed greater improvement in pulmonary function than the control group, which indicates that the tredmill exercise is effective at increasing the pulmonary function and body mass index 20s obesity.

Purpose: The purpose of this study was to examine the relationship between body image, weight-control self-efficacy, and body mass index of high-school girls. Methods: Body image, gender role identity, weight-control self-efficacy, and body weight control behavior were measured by structured questionnaires. Date were analyzed by descriptive statistics, the t-test, the one-way ANOVA, and Pearson correlation, using the SPSS program. Results: Body weight control behavior was positively correlated with weight-control self-efficacy and objective body mass index. Body weight control behavior showed significant differences according to the interest in weight control, current weight control effort, reasons for weight control, secret method for weight loss, eating breakfast or not, and the amount of time exposed to mass media. In regard to the body weight control behavior according to the gender role identity type, the androgynous showed significantly higher tendency than other types. Conclusion: These findings suggest that health providers need to educate high-school girls about appropriate body image and weight control behavior. Also, more studies are needed to identify factors influencing weight control behavior.
