The importance of direct genetic, maternal, heterosis and epistatic effects were examined on post-weaning weight, height, length, girth, fat depth and muscle (ratio of stifle to hip width) with dry and wet season gains in these traits. The breeds used were two pure breeds (Jersey and Limousin), the Limousin${\times}$Jersey $F_1$, and two backcrosses ($F_1{\times}$Jersey dams and $F_1{\times}$Limousin dams). Direct genetic effects were large (p<0.001) for all traits except for length. Jersey maternal effects were large for weight, girth, fat depth and muscle in the post-weaning wet season gains which is an evidence of the impact of Jersey dam on progeny beyond weaning. There were large heterosis effects on fat depth and muscle relative to other traits. Epistatic effects were observed for post-weaning performance in weight, girth, fat depth and muscle. There are indications that there were different genetic effects for post-weaning compared to preweaning growth traits. Thus, it could be hypothesized from this study that different quantitative trait loci (QTL) affect early and late growth in Jersey and Limousin cross cattle breeds. The follow up work will examine the different chromosomal gene effects on pre- and post-weaning growth.

Objectives: The purpose of this study was to compare predictions and measurements of the resting energy expenditure (REE) of overweight and obese adult women in Korea. Methods: The subjects included 65 overweight or obese adult women ranging in age from 20~60 with a recorded body mass index (BMI) of 23 or higher. Their height, weight, waist-hip ratio, and blood pressure were measured. The investigator also measured their body fat, body fat percentage, and body composition of total weight without fat using Dual energy X-ray absorptiometry (DXA) and measured resting energy expenditure by indirect calorimetry. Measured resting energy expenditures were compared with predictions from six methods: Harris-Benedict, Mifflin, Owen, WHO-WH, Henry-WH, and KDRI. Results: Harris-Benedict predictions showed the smallest differences from measured resting energy expenditure at an accurate prediction rate of 70%. The study analyzed regression between measured resting energy expenditure and body measurements including height, weight and age. The formula proposed by this research is as follows: Proposed REE equation for overweight and obese Korean women = $721-(1.5{\times}age)+(0.4{\times}height)+(9.9{\times}weight)$. Conclusions: These findings suggest that age is a significant variable when predicting resting energy expenditure in overweight and obese women. Therefore, prediction of resting energy expenditure should consider age when determining energy requirements in overweight and obese women.

In the present study, a randomized, double-blind, placebo-controlled trial to determine the effect of conjugated linoleic acid (CLA) supplementation (50:50 ratio of cis-9, trans-11 and trans-10, cis-12 isomers) for 8 weeks on body composition and biochemical parameters in healthy overweight/obese (body mass index, BMI${\geq}23\;kg/m^2$) Korean subjects was performed, Thirty participants (3 males and 27 females) were randomized to receive placebo (2.4 g olive oil/day) or 2.4g/day CLA (mixture containing 36.9% of cis-9, trans-11 and 37.9% of trans-10, cis-12). Eight weeks of CLA supplementation significantly decreased body weight by -0.75kg, BMI by $-0.27\;kg/m^2$, and hip circumference by -1.11 cm. The reduction of body weight was ascribed to the reduction of body fat mass (-0.59 kg) and lean body mass (-0.18 kg), although these changes were not significant. No significant differences in serum lipid profiles, liver function enzyme activities, and protein concentration were observed in either the CLA or placebo groups. These results indicate that short tenn supplementation (8 weeks) with CLA (2.4 g/day) may decrease body weight in Korean overweight/obese subjects.

Anthropometry, computed tomography(CT) at the umbilical level, nutrient intake, blood pressure, serum levels of lipids and lipoproteins and response of glucose, c-peptide, insulin, and free fatty acid(FFA) during oral glucose tolerance test(OGTT) were estimated on 11 normal-weight controls and 35 overweight and obese middle-agd men. The areas of total abdominal, subcutaneous and visceral were determined by CT scanning technique. Total abdominal fat area correlated the most significantly with the levels of serum lipids, lipoproteins and insulin among several obese indices. Compared with normal-weight controls, overweight and obese men with abdominal fat lower than 29000$\textrm{mm}^2$ showed an increase in waist-hip ratio, areas of total abdominal(35%), visceral and subcutaneous fat and C-peptide response area during OGTT, though age, percent ideal body weight, body mass index, % body fat, and all biochemical indices except C-peptide response area were not different between two groups. Overweight and obese men with abdominal fat greater than 29000$\textrm{mm}^2$ showed a higher values in total abdominal fat(85%), serum levels of triglyceride, total-and LDL-cholesterol, the ratio of LDL-to HDL-cholesterol, and response areas of FFA, insulin and C-peptide during OGTT than normal-weight controls. Overweight and obese men with great abdominal fat showed an increase in alcohol ingestion and percent calorie intake per total energy expenditure, compared with normal-weight controls. Our results indicate that obesity and a certain level of total abdominal fat accumulation is required to observe abnormal levels of serum lipids, lipoproteins and insulin in Korean middle-aged men. In addition, increased alcohol and calorie intake and decreased physical activity could partly explain total abdominal fat accumulation in men.

The purpose of this study is to analyze the level of obesity and sarcopenia among chronic obstructive pulmonary disease(COPD) patients in Korea. The current study recruited 75 patients with COPD who visited the department of respiratory medicine at J University Hospital in J-do. Height, body weight, waist circumference, and hip circumference were measured, and body composition, muscle strength, and flexibility were assessed. The levels of obesity were classified with body mass index(BMI), waist-hip circumference ratio(WHR) and percent body fat, and sarcopenia was classified with the value of skeletal muscle mass and muscle strength by Asian Working Group for Sarcopenia. In results, it was found that the level of obesity was very high as 43% by BMI, 88% by WHR, and 64% by percent body fat. The lower level of muscle strength was 15.50% in males and 23.50% in females. The lower level of muscle mass was 24.10% in males and .00% in females. Males who had one sarcopenia factors were 22.40%, and females were 23.50%, respectively. Males with sarcopenia were 6.90%, and females were .00%. In conclusion, regular resistance exercise is essential not only for the development of motor skills, but also for the normalization of skeletal muscle function and prevention of muscle dystrophy among COPD patients.

Purpose: The purpose of this study was to identify whether neck circumference might be correlated with other obesity indices and to determine the neck circumference cutoff level for obesity in female college students. Method: The data were obtained by measuring other anthropometric indices including BMI and neck circumference from 325 female college students in J city, Chungbuk Province. Receiver Operating Characteristic curve(ROC curve) analysis was used to find the optimal neck circumference cutoff level against BMI $25kg/m^2$. Results: The mean BMI was $21.4kg/m^2$, and the prevalence of obesity was 12.6%. Neck circumference was significantly correlated with body weight, BMI, waist circumference, hip circumference, waist to hip ratio, % body fat, triceps skinfold thickness, systolic and diastolic blood pressure. Neck circumference of 31.95cm was the best cutoff level for determining female students with a BMI over $25kg/m^2$, and the characteristic was acceptable with 97.6% sensitivity and 85.6% specificity. Conclusions: Neck circumference was strongly correlated with the other conventional obesity indices. Female college students with neck circumference over 31.95cm require an additional evaluation of obesity.

A study was conducted to investigate the anthropometric indices, fat distribution, eating habits and levels of daily physical activity based on the body mass index (BMI ; kg/㎡) of 180 female college students. This stady was based on survey 2001 using a questionnaire. The results are as follow ; The mean age, height, weight and BMI were 20.41 ${\pm}$ 1.82 years, 161.86 ${\pm}$ 4.51cm, 53.49 ${\pm}$ 7.02kg, and 20.43 ${\pm}$ 2.65kg/㎡, respectively. The group with BMI of under 20 (the lean group) comprised 48.9% : the group with BMI of 20 to 25 (the normal group) comprised 44.4% and the group with BMI of over 25 (the obese group) comprised 6.7% of the subjects. Even though the lean and the normal groups were determined according to BMI. 12.5% of the lean group and 31.3% of the normal group had more than 25% body fat. Of the students, 11.5% of the lean group, 25.0% of the normal group and 58.3% of the obese group had of more than 0.8 waist/Hip Ratio (WHR). The medical problems suffered by the subjects were constipation (24.4%), gastroenteritis (20.6%), anemia(15.0%) and edema(13.3%), which was a result of their eating habits. Out of all the subjects, 27.2% ingested their meals irregularly, 74.4% skipped breakfast, and 92.4% of the lean group, 89.2% of the normal group and 81.8% of the obese group ingested snacks on a daily basis. Their favorite types of snacks were cookies breads and cakes (33.7%), spicy sliced rice cakes pork sausage and boiled fish cakes (18.5%), fruits (15.2%), juices and sodas (13.5%) and hamburgers and pizzas (3.9%). Their consumption of high calorie and processed foods was high, Of the subjects, 38.9% ate out daily. 45.1% had tried weight loss. Those with large upper bodies comprised 11.5%, large intermediate bodies 18.5% and large lower bodies 69.0%. Most of the students were dissatisfied with their body snaps. Of the subjects, 95.1% exercised irregularly. Daily physical activity tended to increase significantly with an increase in BMI : the lean group's average energy consumption was 1509.40㎉ the normal group's was 1792.21㎉ and the obese group's was 2334.63㎉, which were below the recommended value. This study suggests that the maintenance of an ideal weight, the improvement of eating habits and adequate exercise are needed for female college students to improve their health and nutritional status.

Objectives: The purpose of this study was to evaluate changes in body weight and blood pressure and also analyze adverse events after weight loss program using Gamitaeeumjowee-tang in patients with class II or III obesity, considering for metabolic and bariatric surgery. Methods: A retrospective chart review was conducted on class III obesity or class II obesity patients with comorbidities, who participated in 24-week weight loss program using Gamitaeeumjowee-tang (n=54). The analysis included changes in body weight, body mass index, fat mass, skeletal muscle mass, waist-hip ratio and blood pressure before and after the program. And also calculated the proportion of patients who lost more than 5%, 10%, and 15% of their initial weight. Adverse events were assessed by causality, severity and system-organ classes. Results: After the weight loss program, body weight decreased 12.21±6.43 kg (12.77%), and BMI decreased 4.61±2.25 kg/m² (12.75%) on average (P<0.05). The 90.7% of the subjects lost more than 5% of their weight, 68.5% lost more than 10%, and 35.1% lost more than 15% of their weight. Blood pressure significantly decreased 11.04±14.53 mmHg in systolic and 7.28±11.89 mmHg in diastolic on average (P<0.05). The 97% of adverse events were mild, and 75% were evaluated as 'unlikely' in the causality evaluation. Conclusions: The results of this study, the weight loss program using Gamitaeeumjowee-tang showed significant weight loss and blood pressure reduction in patients with class III obesity or class II obesity with comorbidities, without serious adverse events. Well-designed clinical studies are recommended for the future.

Purpose: The purpose of this study was to identify the impact of obesity on the incidence of diabetes mellitus in adults with pre-diabetes. Methods: This study employed a longitudinal study design and utilized secondary data drawn from the Korean Genome and Epidemiology Study. This study used data from a sample of 3,693 adults with prediabetes who were followed every two years from 2001 to 2018. Statistical data analysis for frequency, number of cases per 1,000 person-years, log-rank test, Kaplan-Meier curve, and Cox's proportional hazards regression analysis was performed using IBM SPSS statistics version 26. Results: During the observation period, there were 1,309 (35.4%) patients with diabetes, and the total number of person-years was 35,342. The incidence of diabetes was higher in the obese group compared to the normal weight group (body mass index [BMI]: hazard ratio=1.57, 95% confidence interval [CI]=1.40~1.77, waist: hazard ratio=1.55, 95% CI=1.38~1.76, waist to hip ratio [WHR]: hazard ratio=1.53, 95% CI=1.24~1.89, body fat [BF] (%): hazard ratio=1.42, 95% CI=1.27~1.61). Conclusion: An increase in BMI, waist circumference, and WHR, which are indicators of obesity, can exacerbate the risk factors for diabetes. Thus, a decrease in BMI, waist circumference, and WHR is necessary to prevent pre-diabetes. In particular, health care professionals should provide individualized weight management program interventions, including adult obesity programs and obesity counseling in partnership with local health departments, to reduce BMI and waist circumference in people at high risk for diabetes.

This study was done to investigate and compare the nutritional status and plasma lipids in the diabetes and control elderly. Subjects were 105 persons (male 32, female 73) aged over 65 years and visited public health centers in Ulsan area. The subjects were divided into 2 groups, diabetes and control group. Athropometric measurement, dietary intakes, and plasma biochemical indices were examined. Body Mass Index (BMI), Percentage of Ideal Body Weight (PIBW) and Waist-Hip Ratio (WHR) of diabetes group were higher than those of control group. Overall eating behavior were worse in diabetes group than those of control group. There was no significant difference in smoking and exercise status among groups. The ratio of drinkers was significantly higher in control group. But the amount of alcohol consumed at once was higher in the diabetes group. There was no significant difference in most nutrient intakes between males and females. The intakes of fiber, natrium (Na), vitamin A, and $\beta$-carotene were significantly higher in diabetes group than control groups while that of potassium (K) was lower in diabetes group. Diabetes group had the higher levels in triglyceride, VLDL-cholesterol, Chol/HDL-cholesterol ratio, LDL/HDL-cholesterol ratio, while they had lower HDL-cholesterol level. Overall results might imply that the elderly with diabetes have to be more careful to their meals and health-related behaviors to increase the likelihood of a healthier life.
