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.

Young-Soon Choi 보안공학연구지원센터 2016 International Journal of Bio-Science and Bio-Techn Vol.8 No.6

This research assessed the effects of body shape awareness on body mass index (BMI) based on 165 male and female college students in the G city. First, in assessing satisfaction levels of body shape based on body mass index-based normal weight, there were only 7 (36.8%) male students dissatisfied with their body while there were 95 (85.6%) female students feeling dissatisfied (p<0.001). Second, looking at the difference between real body mass index and idealistic body mass index, all 13 real body mass index -based overweight students (100%) wanted to lose weight to reach idealistic body mass index-based normal weight (p<0.001). Third, looking at the association between body mass index and body shape awareness factors, body mass index and interest in body shape were negatively correlated while body mass index and body shape awareness were positively correlated. In conclusion, both male and female students preferred underweight over normal weight, mandating the need to induce the establishment of self-awareness for healthy body shape. Therefore, awaken the importance of eating a thing, due to the false body image does not adversely affect a weight control behavior such as not wrong eating habits formed or validation may be necessary proactive nutrition education and counseling about the correct body awareness and healthy eating.

Objective To analyze how pretreatment body mass index relates to known endometrial cancer prognostic factors and how it impacts the disease-free survival and cause-specific survival of Korean women with endometrial cancer. Methods The patients were divided into the non-obese (<25 kg/m2) and obese groups (≥25 kg/m2) according to their pretreatment body mass index. The 25 kg/m2 body mass index cut-off was based on the World Health Organization criteria for Asian people. The two groups were compared in terms of their clinicopathological characteristics and survival outcomes. Results A total of 213 consecutive patients with endometrioid adenocarcinoma of the uterus met the eligibility criteria of this study and were included in the analysis. Of these patients, 105 patients had a body mass index less than 25 kg/ m2 (non-obese group) and 108 patients had a body mass index equal to or more than 25 kg/m2 (obese group). The two groups did not differ in terms of age, menopause, parity, height, FIGO (International Federation of Obstetrics and Gynecology) stage, tumor grade, tumor size, myometrial invasion, lymphovascular space invasion, cytology, and lymph node metastasis. Body mass index was not a significant factor for disease-free and cause-specific survival in univariate analysis, and after adjusting for all prognostic factors that were significant in univariate analysis, it did not associate significantly with disease-free and cause-specific survival. Conclusion In Korean women with endometrioid adenocarcinoma of the uterus, a high pretreatment body mass index did not associate with other prognostic factors and had little impact on the disease-free survival and cause-specific survival of these women.

Purpose: Testicular volume is one of the important indices that represent the reproductive ability of adult males. In previous studies, however, testicular volume was measured by manual palpation or orchidometer, resulting in inaccuracy or subjectivity. Accordingly, the need for accurate data on the size of the testes is increasing, and we conducted testicular volume measurements by using scrotal ultrasonography. We investigated the relationship between testicular volume and body weight, height, and body mass index (BMI). Materials and Methods: The testicular volumes of 1,002 young adult Korean men were measured for length, width, and thickness with ultrasonography, and data on BMI were collected conventionally. The correlation between testicular volume and BMI was analyzed with one-way ANOVA and Student's t-test. Results: The mean age of the young men was 23.02±2.53 years. The mean testicular volume was 18.09±3.79 cc on the left and 18.26±3.21 cc on the right. Testicular volume was directly proportional to body weight, height, and body mass index. Conclusions: The testicular volume of Korean young adult men was about 18.17 cc. Testicular volume has a weak direct correlation with body weight, height, and body mass index.

연구배경: 비만의 진단을 위해 WHO는 body mass index (BMI) 값을기준으로 삼는다. BMI는 lean body mass와 fat body mass를 구분하지못하므로 bioelectrical impedance analysis를 통해 percent body fat, fatfree mass, fat mass index (FMI) 등의 값을 이용하여 체지방율을 예측한다. 우리나라를 포함한 전 세계적으로 여러 연구를 통해 BMI에근거한 비만의 분류별 FMI 값의 cut-off value를 제시하고 있다. 이번연구를 통해 성별, 연령대별로 FMI 값의 cut off value 값의 분포를살펴보고, 임상적 의의에 대한 고찰을 하였다. 방법: 2018년 5월부터 2019년 5월까지 전국 7개 건강검진센터의 수진자를 대상으로 신체계측과 BIA를통한 체성분분석을 시행하였다. 수진자를 10년 단위로 나누어 20대부터 80대까지 연령별로 구별하여 FMI 값에 대한 분포도를 알아보고, 성별, 연령별로 BMI 기준값에 상응하는 FMI의 cut-off value를 도출하였다. 결과: FMI 분포는 남녀 모두 BMI 기준 정상에서 비만단계까지는평균 FMI 단순평균값의 차이가 거의 없었으며, 고도비만군에서는연령이 증가할수록 FMI 평균값이 줄어드는 경향을 보였다. BMI에상응하는 FMI cut–off value는 남자에 비해서 여자가 평균값 BMI18.5에 해당하는 값은 남:여(3.2:4.5)로 1.3 높게 측정되었고, BMI 25에 해당하는 값은 남:여(6.1:8)로 여자가 1.9 높게 측정되었다. 비만진단기준에 상응하는 FMI 값은 연령대 증가와 함께 상승하였다. 결론: 비만진단기준인 BMI 25에 해당하는 FMI cut off value가 연령별 차이가 있음을 확인하였으며, 남자보다 여자에서 그 차이가 더큼을 확인하였다. 연령별로 일률적인 기준값을 적용하는 데는 주의가 필요하며, 연령이 보정된 FMI 값의 적용이 필요하다. Background: Body mass index (BMI), a standard guideline used by the World Health Organization to diagnose obesity, has limited ability to differentiatebetween lean body mass and fat body mass. Bioelectrical impedance analysis (BIA) is commonly used to value body adiposity to calculate percentbody fat, fat free mass, and fat mass index (FMI). Numerous studies have published a population-based cut-off value of FMI corresponding to BMI tobetter assess obesity. This study aimed to suggest an FMI cut-off value that is indicative of obesity and understand any limitations to its clinicalapplication. Methods: From Jan 2017 to Dec 2018, this multicenter cross-sectional study was conducted among 618,757 community-dwelling healthy Koreansaged 20 years or older. Body composition parameters were measured using BIA. FMI was calculated for each age group and obesity classificationgroup. Results: The mean reference values of the reference groups were as follows: FMI 6.1 for men and 8 for women for those with BMI >25 and FMI 3.2 formen and 4.5 for women for those with BMI <18.5. When subjects were divided by 10-year age groups, the FMI cut-off value for the diagnosis ofobesity varied and the value increased with aging. Conclusion: FMI reference values varied among age groups. FMI values for women were distributed in a wide range and had larger differences in thesame obesity group. It is essential to apply age-specific FMI reference values to patients to achieve optimum body composition analysis.

Body composition index obtained by using a bioelectrical impedance analysis device can be a predictor of prolonged operative time in patients undergoing minimally invasive colorectal surgery

Purpose: Obesity has been known to contribute to technical difficulties in surgery. Until now, body mass index (BMI) has been used to measure obesity. However, there are reports that BMI does not always correspond to the visceral fat. Recently, bioelectrical impedance analysis (BIA) has been used for body composition analysis. This study aimed to evaluate the usefulness of the body composition index obtained using a BIA device in predicting short-term postoperative outcomes. Methods: Data of patients who underwent elective major colorectal surgery using minimally invasive techniques were reviewed retrospectively. Body composition status was recorded using a commercial BIA device the day before surgery. The relationship between BMI, body composition index, and short-term postoperative outcomes, including operative time, was analyzed. Results: Sixty-six patients were enrolled in this study. In the correlation analysis, positive correlation was observed between BMI and body composition index. BMI and body composition index were not associated with short-term postoperative outcomes. Percent body fat (odds ratio, 4.226; 95% confidence interval [CI], 1.064–16.780; P=0.041) was found to be a statistically significant factor of prolonged operative time in the multivariate analysis. Correlation analysis showed that body fat mass was related to prolonged operative time (correlation coefficients, 0.245; P=0.048). In the area under curve analysis, body fat mass showed a statistically significant predictive probability for prolonged operative time (body fat mass: area, 0.662; 95% CI, 0.531–0.764; P=0.024). Conclusion: The body composition index can be used as a predictive marker for prolonged operative time. Further studies are needed to determine its usefulness.

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.

Bac㎏round: Whole body vibration exercise is currently being researched for potential therapeutic and exercise performance benefits. Little is known about the physiological effects of whole body vibration on humans. The aim of this study was to examine the effects of whole body vibration on body weight and body compositions. Methods: One hundred and twelve healthy college students were separated into two groups; one was the whole body vibration exercise group, the other the control group. The exercise program was more than 10 minutes of whole body vibration exercise and the frequency was more than 3 times per week during three months. Body weight and body composition were checked at the beginning and the end point of this study. Results: A total of 91 students finished this study (56 males, 35 females). No significant difference was found in body weight, body mass index, muscle mass, fat mass, body fat ratio, visceral fat area between the study and the control groups. In females, slight increase as found in body weight (exercise vs. control; 1.1 ± 1.1 ㎏ vs. 0.3 ± 1.9 ㎏, P = 0.03), body mass index (0.5 ± 0.4 ㎏/㎡, 0.0 ± 0.5 ㎏/㎡, P = 0.002), fat mass (0.8 ± 0.9 ㎏, -0.3 ± 1.4 ㎏, P = 0.008), and fat ratio (1.0 ± 1.5%, -0.6 ± 2.4%, P = 0.03) in the study group compared with the control group, clinically significant or not. The increase mainly occurred in normal body mass index group in the female study group (P < 0.05). Conclusion: The results of this study suggest that whole body vibration exercise has no significant effect on reducing body weight and fat mass, visceral fat area and on increasing muscle mass. 연구배경: 수직진동운동기는 신체에 지속적인 진동을 가해주는 근력 운동기로서 최근 우리나라에서 의학적인 검증 없이 일반인들에게 널리 사용되고 있다. 그러나 아직까지 수직진동운동기가 신체에 미치는 영향 및 체중과 체성분에 미치는 효과는 알려지지 않았다. 본 연구에서는 수직진동운동기가 체중과 체성분에 미치는 영향을 알아보고자 하였다. 방법: 20-30대의 서울시 일개 의과대학교 2학년과 3학년 학생 112명을 대상으로 임의로 실험군과 대조군의 두 그룹으로 배 정하여 실험군에서는 3개월 동안 최소 주 3회 이상, 10분 간의 수직진동운동을 시행하도록 하였고 대조군에서는 일상적인 생활을 지속하도록 하였다. 두 군의 실험 전과 3개월 후의 공 복 시 체중과 체성분을 분석하여 비교하였다. 결과: 최종적으로 연구에 끝까지 참여한 91명(남 56명, 여 35 명)을 남녀별로 분석한 결과 남자에서는 실험군과 대조군 간 에 체중, 체질량지수, 근육량, 체지방량, 체지방률, 내장지방 면적에서 유의한 차이를 보이지 않았다. 여자에서는 임상적 의미는 확실하지 않으나 실험군에서 체중(실험군 1.1±1.1 ㎏, 대조군 0.3±1.9 ㎏)과 체질량지수(실험군 0.5±0.4 ㎏/㎡, 대조 군 0.0±0.5 ㎏/㎡), 체지방량(실험군 0.8±0.9 ㎏, 대조군 -0.3±1.4 ㎏), 체지방률(실험군 1.0±1.5%, 대조군 -0.6±2.4%)이 약간 증 가하였다(P<0.05). 이러한 증가는 주로 연구시작 당시 체질량 지수를 기준으로 저체중, 정상체중, 과체중, 비만군의 4군으로 분류하였을 때 정상체중이었던 여자 실험군에서 증가하였다 (P<0.05). 결론: 수직진동운동기는 젊은 남녀 성인에서 체중 감량 및 체 지방, 내장 지방을 줄이는 효과가 관찰되지 않았고, 근육량을 증가시키는 데에도 유의한 효과가 없었다.

( Bokun Kim ),( Sechang Oh ),( Eonho Kim ) 국민체육진흥공단 한국스포츠정책과학원 2019 International Journal of Applied Sports Sciences Vol.31 No.1

The purposes of this study were twofold: (a) to examine role of body mass index in incidence of low back pain and (b) to investigate more relevant causes of low back pain in body composition. Of the 250 initial subjects, 188 subjects were included for the first analysis and divided into quartiles based on the scores of Japan Low Back Pain Evaluation Questionnaire which was adopted to assess low back pain. We selected 51 subjects (body mass index: 27.4 ± 5.0 kg/m²; age: 47.4 ± 10.9 years) in 1st quartile as a control group and 45 subjects (body mass index: 27.1 ± 2.8 kg/m²; age: 56.4 ± 7.1 years) in 4th quartile as a low back pain group for the final analysis. Assessments of anthropometric characteristics and body composition (by whole-body dual-energy X-ray absorptiometry) were carried out and body composition was evaluated as absolute and relative values. No difference in body mass index between the two groups was detected and waist hip ratio and percentage of trunk fat mass per weight in low back pain group was significantly greater than those in the control group. While low back pain was significantly related to abdominal fat related variables including waist, waist hip ratio and percentage of trunk fat mass per weight, it was not linked to other variables such as weight and body mass index. Abdominal fat accumulation may be a potential risk factor for low back pain in adult men.
