Purpose: This article tried to find the relations between periodontal diseases, body mass index and clinical level for Korean adults over the age of 19, utilizing data of the 6th national nutrition survey. Methods: In the collected data, 14,940 adults aged 19 years or older were included in the study to determine the relationship between the general health status of Korean adults and periodontal disease. Results: As the result, 28.6% of Korean adults had periodontal diseases, there were significant differences depending on gender, age, smoking, residential aria, education level, body mass index, HDL-cholesterol, leukocyte value and fasting blood sugar. When general factors were controlled for multiple logistic regression analysis, there was significance as BMI cross rate was 1.029(95% C1, 1.007-1.051). HDL-cholesterol cross rate was 0.989(95% C1, 0.980-0.999), leukocyte cross rate was 1.086(95% C1, 1.040-1.134) and fasting bloody sugar cross rate was 1.006(95% C1, 1.003-1.009), so there were significance. In conclusion, there was a significance relation between periodontal diseases, body mass index, HDL-cholesterol and fasting bloody sugar. Conclusion: Based on the results of this study, oral health education should be used to manage and maintain healthy oral cavity by improving periodontal disease management and awareness. In addition, it will be necessary to develop periodic oral examinations and age - specific oral health education programs, and it can be used as a basic data for public oral health plan.

The purpose of this research is to analyzed the Korean adolescents' weight control behaviors by BMI(Body Mass Index) and body shape perception. The data of this study abtained 73,238 adolescents, aged 12-18years from the '2010 6th Korea Youth Risk Behavior web-based Survey. The data were analyzed by frequency, percentile, chi-square test, Binominal Logistic Regression analysis. The results of this research were as following. First, the answer to question about adolescents' body shape perception is high in "normal" and "a little fat", but the result of BMI show that the most of them are in "underweight". Second, the female students tends to perceive themselves obese than male students do. Third, the female student try to lose weight but male student try to gain weight. Also the higher BMI is, the more the student have tendency to try to lose their weight. In conclusion, BSP leds directly weight control behavior, so in order to reduce unnecessary weight loss or improper methods weight control behavior. It is important to educate the students to have a sound perception about body shape.

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.

This study examined the state of health and weight maintenance according to the body mass index (BMI) , and explored demographic variables, diet variables, the degree of stress etc. The results presented were based on data collected from 428 women who are mothers of the middle school children in Jeongeup city. Using SPSS WIN (Ver 9.0) , the frequency, percentage, mean, standard deviation, chi-square, ANOVA, and correlation analysis were provided. The mean of BMI for the subjects was 22.6, the ratio of obese women (BMI $\geq$ 25) was 22.9%. The frequency of the reported circulation or respiratory related diseases was greater in the obese group compared to the normal weight ($20 \leq BMI \leq 25$) or the lean (BMI < 20) groups. The obese group had less awareness of obesity. Those who regard themselves obese had lower rates of satisfaction with their body shape and higher rates of interest in weight control. Approximately 65% of the subjects attempted weight reduction more than once. Subjects who were obese had the most undesirable dietary behavior. In particular, this group had the higher rates of rushed meals, overeating, meals while watching TV or newspapers, and snacking, and eating out. In analyzing the correlation of variables influencing obesity, there were positive correlations between obesity and overeating, obesity and the degree of stress. Correlations between obesity and satisfaction for life found to be negative. Moreover, stress had a positive correlation with obesity and overeating, and showed negative correlation with eating behavior. Consequently, stress seemed to induce undesirable eating behaviors and increase obesity. Of the demographic background variables, subjects who were obese tended to be older, had lower levels of education, higher rates of employment, longer period of marriage, the higher number of children, preschool children or children preparing for highschool or college, lower satisfaction with children and household life.

This study aimed at investigating correlation of nutrients intake and serum lipids of industrial workers. 226 for adult aged 20yr~59yr (average age 35.9yr) were selected as subjects during 6 months, from June to December, 1997. Nutrients intake was investigated by questionnaire, 24-hour recall method. Antropometric assessments, serum lipids and blood pressure of the subjects were investigated. The results as follows ; In total subjects, calories, calcium, vitamin A, vitamin $B_1$, and vitamin $B_2$ were below Korean RDA(recommended dietary allowances) and protein, iron, vitamin C, niacin and phosphorus were above Korean RDA. Distribution of BMI groups were underweight groups(7.9%), normalweight groups(63.3%) and overweight groups(28.8%). In BMI groups, intakes of calories, carbohydrates, protein, fats, iron, niacin and potassium of overweight groups were higher than those of other groups, significantly(P<0.001). Intakes of calcium of underweight groups were lower than those of other groups, significantly(P<0.05). BMI increased with age. Total cholesterol, triglyceride, apo(b) and atherogenic index of overweight groups were higher than those of other groups, significantly(P<0.001). Calories, carbohydrates, protein, fats, iron, vitamin $B_1$, vitamin $B_2$, niacin, natrium and potassium were positively correlated with BMI, significantly(P<0.001). Calcium and vitamin C were positively correlated with BMI, significantly(P<0.01). vitamin A and phosphorus were positively correlated with BMI, significantly(P<0.05). Total lipid, total-chol., triglyceride, apo(b) and atherogenic index were positively correlated with BMI, significantly(P<0.001). HDL-chol. were negatively correlated with BMI, significantly(P<0.001). Above results, the more BMI and age increased, the worse patterns of serum lipid, so that increased atherogenic index that increased risk of atherosclerosis and degenerative chronic disease connected with serum lipid. After classified by BMI, age and lipid pattern, it will be managed individually for health management of industrial workers. Development and application of efficient program will be urgent for harmonious nutrition counseling and guidance.

PURPOSE: This study aimed to identify the clinical factors that contribute to age-related loss of skeletal muscle mass (ALSMM) among young Korean male adults. METHODS: This was a cross-sectional study involving 955 men aged between 20-29 years. They underwent screening to assess the ALSMM. The study examined a variety of factors, including age, height, weight, body mass index (BMI), waist circumference (WC), skeletal muscle mass index (SMI), lifestyle-related habits such as smoking and drinking status, systolic and diastolic blood pressure (SBP/DBP), fasting blood glucose (FBG) levels, as well as the serum triglyceride and total cholesterol (TC) levels. RESULTS: The variables that displayed significant associations with ALSMM were height, weight, BMI, WC, SMI, FBG, TC, DBP, and alcohol consumption (p < .05). Serum triglyceride levels, SBP, and smoking status did not exhibit statistical significance (p > .05). CONCLUSION: The study identified the contributing factors associated with the ALSMM in community-dwelling young adult males. These findings would enrich the current body of literature on ALSMM and provide potential risk factors associated with its development in young Korean males.

The aim of this study was to evaluate the body composition difference and obesity prevalence in grade 5 to 8 by gender. A total of 1,333 students, 707 boys and 631 girls, were recruited from one elementary and one middle school in Seoul, Korea. Anthropometric measurements including height, weight, lean body mass, and body fat were assessed. Height and weight were increased by grade, but Body Mass Index (BMI) by grade showed no significant difference among boys. Lean body mass had growth spurt between 7 and 8 grade among boys compared to gradual increase among girls. Overweight and obesity prevalence were higher among elementary schoolers than middle schoolers. Overweight (BMI for age> $85^{th}$ percentile) prevalence was about $44\%$ among $5^{th}$ grade boys compared $29\%$ among same grade girls. These results provided that there were prominent difference regarding body growth and obesity prevalence in gender and grade. Further studies for children and adolescents should be considered their body composition change.

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.
