Objectives: According to preceding studies, many people with mental disability have unbalanced dietary habits or excessive intake of calories. Most of them are overweight or obese due to lack of self-control for food consumption, swallowing with inadequate chewing and physical inactivity. Therefore, this study aimed to assess the nutritional intake, including carotenoid, in mentally disabled people and find out a possible solution for nutritional improvement. Methods: People with intellectual disability (N=28), emotional disability (N=44) participated in this study. The disorder grades were from I to III and ages were between 20 and 65 years. Assessments included anthropometry, daily intake of nutrients, including carotenoid, ROMA III questionnaire for assessing bowel movement. Results: The average BMI of intellectually disabled people and emotionally disabled people was in the range of overweight and obesity respectively ($23.7{\pm}6.3kg/m^2$, $25.8{\pm}4.1kg/m^2$). Overall, the frequencies of vegetable and dairy product intakes were lower in this population. When compared with Recommended Nutrient Intake (RNI) from Dietary Reference Intakes for Koreans 2010, the intakes of vitamin $B_1$, vitamin $B_2$ and calcium were insufficient in both groups. Also, lycopene intakes of carotenoid were low, compared with traditional Korean diet of the non-disabled people from the second year 2008 of the 4th National Health and Nutrition Survey. In addition, emotionally disabled people also had lower intake of cryptoxanthin. Conclusions: The mentally disabled people in this study showed lower intakes of vitamin $B_1$, vitamin $B_2$, calcium and carotenoids. Based on these findings, we recommend that it is important to encourage mentally disabled people to consume sufficient amounts of such nutrients in order to promote nutritional status.

The purpose of this study was to investigate the relationship between dietary fat intake, anthropometric data, blood lipids, C-reactive protein, and adiponectin in Korean male college students. Forty-eight subjects were divided into 2 groups based on dietary fat intake: UERF (under 30% of energy ratio for fat source), AERF (above 30% of energy ratio for fat souce). We collected dietary intake data using 24-hour dietary recall for 3 days. Anthropometric and biochemical parameters were measured by using standard methods. Segmental body composition analysis was carried out using an 8-electrode multifrequency bioelectrical impedance method of body fat estimation. There was no significant difference in anthropometric data and serum lipid profile between UERF and AERF group. Serum C-reactive protein level was significantly higher in the AERF group compared to the UERF group. Although there was no significant difference in serum adiponectin level between UERF and AERF groups, subjects had lower adiponectin levels. Correlation data show that serum adiponectin level was positively correlated with vegetable intake (p < 0.05). In addition, dietary fat intake had a positive correlation with meat (p < 0.01), whereas a negative correlation with grain (p < 0.01), vegetables (p < 0.05), and fish (p < 0.05). These results suggest that the increased fat intake of non-obese Korean male college students is associated with their increased serum C-reactive protein concentration. Therefore, proper guidelines on fat intake and nutrition education are necessary for the prevention and management of metabolic syndromes.

The objective of this study is to investigate the effects of dietary nutrient intakes for markers of blood glucose and inflammation which is important to the progress of type 2 diabetes and the development of its complications. For this study, 76 adults with diabetes (42 males, 34 females) were recruited from a group of patients who had visited the department of endocrine medicine. Data on anthropometric characteristics, clinical indices such as hemoglobin A1c (HbA1c) and C-reactive protein (CRP), and dietary nutrient intakes were collected. Our results have shown that 66% of subjects were either overweight or obese. Serum analysis indicates that levels of C-peptide, glucose, HbA1c, CRP, triglyceride, LDL-cholesterol were higher than normal range. Results from the dietary nutrient intake survey displayed that intakes of cholesterol and sodium were higher than Dietary Reference Intakes for Koreans. On the contrary, folate intake was lower than the guideline. Within the females, energy contribution from carbohydrate was higher than Korean Diabetes Association guideline. Statistical analysis has revealed a negative correlation between serum HbA1c level and dietary intakes of polyunsaturated fatty acid (PUFA), n-3 PUFA, ${\beta}$-carotene and vitamin E after adjustments for age, BMI, smoking habits, alcohol consumption, exercise and ingestion of diabetes mellitus medication (p<0.05). Serum CRP level was inversely associated with dietary intakes of carbohydrate, protein, vitamin C and fiber (p<0.05). Our results suggest that dietary nutrient intakes may influence the levels of HbA1c and CRP, and subsequently, it may help in the management/treatment of type 2 diabetes.

Many epidemiological and observational studies show that distorted body image of normal body weight is widespread among Korean young females. This study was performed to evaluate the prevalence of overweight and underweight of young females and, to compare nutrient intakes, body composition, serum indices (lipids, MDA: Malondialdehyde, TAS : Total Antioxidant Status) with different BMI groups. The subjects were 75 university students in Seoul. We divided the subjects into 3 groups according to their BMI by IOTF guideline (UW: underweight group, BMI < 18.5, NW: normal body weight group; 18.5 $\leq$ BMI < 23.0, OW: overweight group; BMI $\geq$ 23.0). Data on dietary intakes, body compositions and serum indices were obtained in 3 groups. Differences on all of the above variables were assessed by body weight groups. Using IOTF guidelines, the prevalence of overweight and underweight in young females were 23%, 61%, 16% respectively. $\beta$-carotene and vitamin A intake of UW were significantly higher than that of NW (p < 0.05). Fiber intakes of NW was significantly higher than that of W (p < 0.05). But intakes of energy and the other nutrients were not significantly different among BMI groups. Calcium and folate intakes were 75%, 61% of KDRIs. Serum TGs were significantly higher in OW than that of NW, UW (p < 0.05), but level of MDA and TAS were not significantly different. The association of overweight and low intake of $\beta$-carotene and vitamin A may be one of many factors predisposing obese females to a high risk of oxidative stress later in life. This requires urgent nutritional intervention programs involving enough intake of fruit and vegetables, with modification of inappropriate dietary habits.

A survey was conducted to determine the relationship between BMI and the dining out behaviors of 316 university students in Seoul area for May and September, 2006. The subjects included 114 males and 202 females. General characteristics and BMI determined that of the students 56 (17.7%) were underweight, 222 (70.3%)were normal, 23 (7.3%) were overweight, and 15 (4.7%) were obese. There were differences in BMI according to age, sex, and major. Students majoring in natural science and engineering were 58.3% and 51% normal weight, respectively, and the next most common weight class was overweight. The non smoking group showed had primarily normal weight subjects followed by underweight-subjects, but the smoking group had primarily normal weight subjects followed by overweight subjects (P<0.001). The frequency of dining out for breakfast significantly correlated with BMI (P<0.05). The group that frequently dined out for breakfast were primarily of normal weight followed by overweight subjects, but the group that rarely dined out for breakfast were primarily of normal weight followed by underweight subjects(21.4%). Groups whose criteria for selecting dining out meals were flavor and price showed a higher percentage of underweight subjects than other groups. The group whose motivations for choosing dining out meals were convenience and habit showed a higher percentage underweight subjects than other motivations. The group that selected the Western food menu for dining out showed a higher percentage of underweight subjects than other food menu groups. And, the groups that selected Japanese and Korean food were primarily of normal weight followed by underweight subjects, but the result was not significant.

This research was planned and executed to evaluate how the composition of Yack-sun (oriental diet therapy) tea can effect the health conditions of people who are suffering from diet-related diseases such as being overweight, obese and hyperlipidemic, by taking Yack-sun tea in a form of nutritional supplement with daily meals. We produced Kangjieum with Lycense Mill., Polygonum multflorum Thunb, Cassia tora L., Crataegus pinnatifida Bge and Salvia miltiorrhiza Bge. We evaluated the effects of this tea on serum lipids, on homocysteine concentration, and on active oxygen contents, oxidative stress by clinical practices. We have determined that this tea has a significant effect on decreasing body fat content, decreasing total cholesterol, decreasing LDL-cholesterol, and decreses triglyceride and homocysteine concentrations. In addition, blood active oxygen content and oxidative stress were significantly decreased. We think that scientific and objective evaluation was performed on the components of Kangjieum prescription. We concluded that we could apply the components, not only in a form of tea, but also in other forms of various foods. The information we received from this conclusion will be basic information on how we can apply oriental medicinal resources into other food and will be a steppingstone for medicinal herbs to place a foot in the field of functional food research, which already draws sizable attention world-wide.

BACKGROUND/OBJECTIVES: The obese population is rapidly increasing because of reduced physical activity and a Westernized diet; consequently, various chronic diseases are more prevalent. With the increasing interest in body shape and appearance, research on body shape perceptions and accompanying weight control behaviors are needed for healthy weight management. SUBJECTS/METHODS: A cross-sectional survey was conducted on randomly selected 536 (209 men and 327 women) aged 20 to 65 years. Body mass index (BMI), body-shape perception, weight control behavior, quality of sleep, and place of residence were collected using self-reported questionnaires. Multivariable logistic regression analysis was conducted using complex design in each groups. Collected data were analyzed using the SAS 9.4 statistical package, and the significance level was set at P < 0.05. RESULTS: When these two variables were divided into four groups, they were found to influence dieting attempts. People with abnormal weights who were dissatisfied with their body shapes attempted dieting 5.23 times more than those with healthy weights and satisfaction with their body shapes. Further, those with normal weights but dissatisfaction with their bodies attempted dieting 4.45 times more than those who were satisfied with their shapes. Subjects in their 20s attempted dieting 2.53 times more than those in their 30s and 40s, and female subjects attempted dieting 2.24 times more than male subjects. CONCLUSIONS: A correct perception of one's shape can be an important factor for dietary behavior, as body shape perceptions and dieting attempts are strongly related. Additionally, healthy weight management and nutrition education are important elements to incorporate into a weight control program aimed at preventing excessive weight control behaviors and promoting correct perceptions of body shape.

This study was carried out to evaluate the body fat breakdown during topical seaweed extract treatment and in combination with the iontophoresis method to enhance skin absorption of lipolytic compounds. Of 14 female obesity subjects, 7 treated a gel types of seaweed extract only(control group) and 7 treated in combination with the iontophoresis(experimental group). Topical treatment of each sample was designed for 2 weeks, treated with 2 times a day about $10m{\ell}$ on the abdomen, triceps and thigh, respectively. Experimental group treat with the iontophoresis during 5 minutes immediately after topical treatment. After one and two weeks of topical treatment, measured body fat, skinfolds thickness, body circumference respectively. Then venous blood samples were taken and analyzed serum lipids. The results were as follows; 1) There were decrement of body weight, $\%$ of body fat, abdomen, triceps and thigh circumference and abdomen, triceps and thigh thickness between pre and post treatment in both group. These decrement were predominant in the iontophoresis treated group. Especially, there were $16\%$ of body fat decrement in the experimental group after two weeks iontophoresis treatment(control group VS experimental group = $33.54{\pm}2.70$ VS $28.37{\pm}3.38$, p<0.01). 2) There were decrement in total CHOL, LDL, TRIG and increment in HDL in both group. These phenomena were predominant in the iontophoresis treated group. CHOL decrement in the experimental group were significant after two weeks iontophoresis treatment(control group VS experimental group = $190.24{\pm}34.36$ VS $157.76{\pm}24.45$, p<0.001). These results suggest that the topical treatment of seaweed extract effective for fat breakdown and maximized in the combination with the topical seaweed extracts treatment and the iontophoresis.

This study was to investigate the level of serum lipids and obesity in housewives in Mooan, and relationships between them. The average age, height and weight were 51.1 years, 154.3cm and 58.3kg respectively. The level of obesity of subjects was higher than that of housewives in other areas investigated in other studies. BMI and RBW underestimated in the obese compared to BIA. The amounts of lean body mass and total body water of subjects above 60 years old were smaller than those of forties and their BMI and RBW were lower than those of forties. However, their body fat percentage was nearly same as that of forties. Serum HDL-cholesterol(HDL-C) of subjects was lower than 55mg/㎗, the lower limit of normal range. Triglyceride of subjects above 60years old was higher than the 95th percentile of those of the same age with reference to Mayo clinic. The serum total cholesterol(TC) showed positive correlation with LDL-cholesterol(LDL-C) and TC/HDL-C(p<0.001). LDL-C showed positive correlation with TC(p<0.001), but negative correlation with HDL-C(p<0.05). HDL-C showed negative correlation with triglyceride(p<0.05). TC/HDL-C showed a positive correlation with triglyceride(p<0.05). HDL-C was the serum lipid which showed the highest correlation with obesity and body composition. It showed a negative correlation with the percentage of body fat(p<0.001), total body fat(p<0.001), BMI(p< 0.05) and RBW(p<0.05). TC/HDL-C showed positive correlation with the percentage of body fat(p<0.01) and total body fat(p<0.05). As the result of above, it is needed to make more researches to find out the proper method to estimate the obesity of subjects and educate subjects in Mooan about nutritional information for obesity.

This study examines the multilateral characteristics of elderly body shapes by applying body measurement items and obesity indices (BMI, WHR, WHtR, WC, and flatness). The subjects were 397 males, 378 females aged 70-85 from the $6^{th}$ Size Korea and 132 males, 212 females aged 60-69, 596 males, 650 females aged 20-29 from the $7^{th}$ Size Korea. In order to examine the body size differences among age groups, age was divided into 7 groups (20-24, 25-29, 60-64, 65-69, 70-74, 75-79, and 80-85). Both elderly males and females showed lower values of height and weight than those in their 20s. However, abdominal obesity indices (WHR and WHtR) showed higher values in the elderly than those of their 20s; in addition, they showed larger mean values as age increased. The chest and arm circumference tended to decrease in elderly males as age increased; however, elderly females tended to decrease in thigh and calf circumference size. There were gender differences in body changing due to aging. Obesity frequency was significantly higher in the elderly than in the 20s. The study represents basic data for product design for the elderly.
