The nutritional status of middle-aged overweight and control normal subjects were evaluated for the purpose of providing the background information of the degenerative disease control. A survey was conducted with 293 healthy subjects (121 males and 172 females) between the ages 40-64. The average BMI (body mass index) of male subjects was 24.5 $\pm2.75$, and that of females was 23.5 $\pm2.87$. The average values of WHR (waist-hip ratio) were 0.88 $\pm0.04$, for males and 0.82 $\pm0.07$, for females. The normal BMI group (BMI 18.5-22.9) comprised 28.9% of males and 47.1% of females. The percentage of overweight subjects (BMI 23-24.9) was 26.4% of males and 30.8% of females. The obese group (BMI ＞ 25) was 44.6% of males ana 22.1% of females, showing the greater rate of obese state among male subjects. The average energy intakes were 76.6 $\pm14.9$% for males and 77.8 $\pm12.6$, % for females, protein intakes were 108.0 $\pm24.6$% for males and 111.2 $\pm22.7$, % for females of the RDA levels. The average intakes of other nutrients were above the 75% of RDA levels except calcium. The average nutrient intakes of the three subgroups according to their BMI values were not different for both males and females. There were weak correlations between obesity and blood biochemical indices. There were positive correlations between BMI or WHR and hemoglobin, hematocrit, fasting glucose, total cholesterol, triglyceride, AST or ALT. There were negative correlations between BMI or WHR and HDL-cholesterol. These results suggest that the obesity rate of middle-aged is an influential factor of chronic disease. The middle-aged subjects of this study with higher educational and socioeconomic background tend to have desirable nutrition knowledge and attitude, but the application of their knowledge or attitude was relatively poor.

Background Bone marrow involvement (BMI) affects the lymphoma stage, survival, and treatment. Bone marrow biopsy (BMB) and fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET/CT) are useful techniques to detect BMI. Both have advantages and disadvantages. We aimed to identify factors that could be used to predict BMI with positive and negative results on PET/CT compare them with BMB in newly diagnosed patients with lymphoma. Methods We included 22 non-Hodgkin and 16 Hodgkin lymphoma patients in this single center study. All patients had PET/CT examination and BMB before treatment. BMI in BMB was reported as negative or positive. Bone marrow was classified into 3 types by FDG uptake on PT/CT; diffuse involvement, focal involvement, and normal bone marrow. Results PET/CT and BMB results were concordant (7 positive, 15 negative) in 22 patients (57%). We evaluated concordant and discordant patient characteristics and risk-stratified patients for BMI. Our findings suggest that patients with diffuse FDG uptake on PET/CT, especially patients with advanced age and low platelet and white blood cell counts, are likely to have BMI and could potentially forego BMB. Patients with negative PET/CT findings and no significant laboratory abnormalities are very unlikely to have BMI. Conclusion Our results suggest that BMI should not be decided solely based PET/CT or BMB findings. It is reasonable to use both diagnostic assays along with clinical and laboratory findings. PET/CT result, clinical and laboratory findings could be useful for predicting BMI in patient for whom BMB is contraindicated.

We aimed (a) to investigate the associations between age, body mass index (BMI), and breast size with mammographic density based on the breast imaging reporting and data system (BI-RADS) and volumetric breast density measurement (VBDM) with Volpara, (b) to evaluate the associations of age, BMI, and breast size with fibroglandular tissue volume (FGV), and (c) to demonstrate the association of mammographic density grade with FGV. From April 2012 to May 2012, 1,203 women consecutively underwent mammography, and their breast density was calculated using the density grade and volume determined by Volpara. In total, 427 women were included in this study. The BMI and breast size of the 427 women were determined. The associations between mammographic density and age, BMI, and bra cup size were assessed. In addition, the associations between FGV and age, BMI, bra cup size, and mammographic density were assessed. The mean age of the women was 51 years (range, 27-83). Age was associated with mammographic density based on BI-RADS (P<0.0001), and both age and BMI were associated with mammographic density based on Volpara (P<0.0001). The mean FGV significantly decreased as age increased (P<0.0001) and increased as BMI and bra cup size increased (P<0.0001 and P=0.0007, respectively). Age was associated with mammographic density, according to both the BI-RADS and VBDM; however, BMI was only associated with mammographic density based on the VBDM. Larger FGV was associated with younger age, higher BMI, larger bra cup size, and higher mammographic density

This study was performed to examine the dietary and BMI change of Koreans after moving to America and to identify the factors influencing changes of BMI. The subjects were 192 Korean-Americans (men : 86, women : 106) residing in the eastern area of the U.S.A. 1) subjects reported significantly increased consumption frequency in American foods like, low fat milk(p<0.001), cold cereals (p<0.001), whole wheat bread(p<0.001), hamburger(only in males p<0.01) and pizza(only in males p<0.01). Whereas significantly decreased consumption frequency in fish (p<0.05), cooked vegetables(p<0.001), kimchi(p< 0.001) and cooked rice (p<0.001) were reported. 2) It was reported that weight, accordingly BMI were significantly increased (p<0.01). The smoking habit score was significantly decreased for males (p<0.05). 3) Multiple linear regression analysis for BMI change showed that education years in Korea was the most prominent negative factor(p<0.001) in predicting BMI change in America. Elevated frequencies of alcohol, chicken and soft drink in America were also associated with greater increase of BMI. When the length of residence (increase of age) was included in regression model, the increase of age was the most significant factor (p<0.001). Changes of chicken and soda scores were other significant factors.

Purpose: The purpose of this study was to identify body satisfaction and weight loss experience according to individual's discrepancy between obesity by BMI (body mass index) and self-assessment. Method: The data were obtained by measuring height, weight and using a questionnaire to obtain data on self-assessment of obesity, body satisfaction and weight loss experience. The participants were 286 women college students in J city, Chungbuk. Results: The mean BMI of the women college student was $21.4{\pm}2.93kg/m^2$ which is within the normal range. The concordance rates between obesity by BMI and self-assessment were 54.1%, 39.9%, 61.5%, 78.6% (Kappa=.29) in underweight, normal, overweight, obese students respectively. Forty seven percent of students who were not obese (BMI $<23kg/m^2$) assessed themselves as obese. The mean body satisfaction of college students was very low and 64.3% of the students had a weight loss experience. The students who perceived themselves to be 'obese' even when their BMI was under $23kg/m^2$ reported lower body satisfaction and higher weight loss experience than other students. Conclusion: There were significant discrepancies between obesity by BMI and self-assessment in women college students. The self-assessment of obesity had a greater effect on body satisfaction and weight loss experience than actual BMI in women college students.

The present study showed WHtR to be significantly better than BMI and WC for prediction of metabolic-related diseases in the middle-aged and older people in Korea, based on Bayesian ordered probit model analysis. The variations of WC, BMI and WHtR were compared according to the number of metabolic-related diseases such as hypertension, dyslipidemia, stroke, myocardial infarction, angina pectoris and diabetes. It was found that the three measures showed the similar variation except a very few extreme cases for age less than 40. For subjects over the age of 40, WC was not significant and WHtR gave more influence in greater variability than BMI on the number of metabolic diseases. Also, the rate of change for WHtR was higher than for BMI as the number of metabolic-related diseases increased. Specifically, the difference of the marginal effect of WHtR between no disease and only one disease was 1.81 times higher than that of BMI. Moreover, it was pointed out that the threshold value of WHtR for obesity should be considered differently by age.

This study was designed to find out how the sociocultural attitudes toward appearance, BMI and body image of adult women affect their self-esteem. A questionnaire was prepared in the survey and a total of 456 adult women were selected by way of stratified random sampling. The research findings are as follows: 1. The sociocultural attitudes toward appearance were shown in two factors of 'internalization' and 'awareness'. The body image was shown in three dimensions of 'care for appearance', 'concern about weight', and 'appearance attractiveness'. 2. Internalization, recognition, and BMI influenced on 'care for appearance'. 'Concern about weight' was affected by internalization and BMI. Appearance attractiveness was affected only by BMI. 3. Adult women's self-esteem was influenced by appearance attractiveness, internalization, and care for appearance. 4. The behaviors of appearance management were differed according to the sociocultural attitudes towards appearance. Therefore, adult women form a higher degree of self-esteem is formed when they accept what they are regardless of their actual BMI and when they evaluate their body positively.

In health promotion program, the fear of gaining weight is often given as a reason for giving up smoking cessation by the participants. The purpose of this study is to compare drinking habit, exercise and BMI distribution according to smoking habits. The subjects of this study were 83 industrial workers in Gu-mi. Data collection was conducted from Sep. 18th to Sep. 24th 2000. The method was self-reported questionnaire survey, consisted of general characterisics, smoking habits and its relevant questions. The results are as follows : 1. Fifty-nine percents of the subjects were currently smoking. 2. Smoking habits were significantly related with drinking(p=.049). More smokers(81.6%) reported drinking habit than non-smokers(61.7%). 3. Forty-one point two percents of the non-smoker and 34.7% of the smoker perceived their body type as "fat". 4. The mean values of BMI were 22.0 in smokers with 1-9 cigarettes/day, 24.2 in 10-19 cigarettes/day smokers and 24.0 in smokers with over 20 cigarettes/day. There are no statistically significant differences in BMI among smoking habits. 5. BMI among different smoking habit groups was not significant different in age, drinking habit, exercise, and smoking habit.

Obesity is a significant problem affecting United States (US) firefighters. While body mass index (BMI) is widely used to diagnose obesity, its use for this occupational group has raised concerns about validity. We examined rates and types of misclassification of BMI-based obesity status compared to body fat percentage (BF%) and waist circumference (WC). Male career firefighters (N = 994) from 20 US departments completed all three body composition assessments. Mean BMI, BF%, and WC were $29kg/m^2$, 23%, and 97 cm, respectively. Approximately 33% and 15% of BF%- and WC-defined obese participants were misclassified as non-obese (false negatives) using BMI, while 8% and 9% of non-obese participants defined by BF% and WC standards were identified as obese (false positives) using BMI. When stratified by race/ethnicity, Pacific Islanders showed high rates of false positive misclassification. Precision in obesity classification would be improved by using WC along with BMI to determine firefighters' weight status.

The purpose of this study is to reduce the dose to the patient by different application of ASIR according to the Body Mass Index (BMI). In particular, we wanted to find out the application values of ASIR that are most appropriate for the standard weight. Studies have shown that increasing the application of ASIR to 50% in patients with a body mass index of 25 or less reduces CTDIvol 58.17% and DLP 60.49% compared to using only FBP. A comparative analysis of the noise by the BMI and the SNR values found that the noise increased as the BMI increased, but the application of ASIR resulted in less noise than the FBP alone. In addition, it was found that the more ASIR is applied, the more SNR is increased.
