The present study was conducted to investigate the effect of nutrition education program on anthropometric values and boichemical index in obese children who live in Gumi city. The subjects were 16 obese boys, 20 obese girls with obesity index over 130 and 36 of their parents. The nutrition education was carried out by the professional personnel such as doctors, professors, and dietitians. The children were provided with well-balanced lunch meals and had 40min-lectures on the reasonable weight management, 40 min-games and also had regular exercises (stretching, swimming) for 90 mins everyday during 2weeks of the program. The parents had 90 min-lectures on childhood obesity, diet therapy, behavior modification, and exercise for 6times. After the program, obesity index, BMI, % body fat were significantly decreased (p < 0.05) in boys and obese index, BMI, % body fat and WHR were significantly decreased (p < 0.05) in girls. Blood cholesterol and TG levels of girls were significantly decreased (p < 0.05). These findings show that the well-designed nutrition education program for obese children can be an effective approach to help them to improve their anthropometric values and biochemical index.

PURPOSE: The present study evaluated the occurrence, somatometric, biochemical, and behavioral characteristics of young Korean sarcopenic males aged between 30 to 39 years. METHODS: The study involved a total of 1,546 participants. These individuals were divided into two distinct groups based on their skeletal muscle mass index. Of these, 49 participants were categorized into the sarcopenia group, while the remaining 1,497 individuals were placed in the normal group. The researchers analyzed the occurrence of sarcopenia, somatometric, biochemical, and behavioral characteristics such as height, weight, body mass index (BMI), waist circumference (WC), skeletal muscle mass index, fasting glucose (FG), triglyceride and total cholesterol (TC) levels, systolic (SBP) and diastolic blood pressure (DBP), and the drinking and smoking status. A complex sampling data analysis was performed. RESULTS: The weighted occurrence of sarcopenia was found to be 3.24%, (95% confidence interval (CI) of 2.39% to 4.36%). The somatometric contributing factors were height, BMI, and WC (p < .05). Triglyceride and TC levels exhibited statistically significant differences in the biochemical variables (p < .05). The behavioral characteristics, including the drinking and smoking status, had no statistical significance (p > .05). CONCLUSION: This study identified specific occurrences of sarcopenia and contributing factors in young Korean men.

This study was conducted to investigate health status of preschool children utilizing anthropometric values and serum biochemical indices. The subjects were 1,159 boys and 1,019 girls in Gumi day-care centers aged 4 to 6 years. The mean height and weight of 4, 5 and 6 year old children were 103.0 cm and 17.1 kg, 107.2 cm and 18.3 kg and 113.4 cm and 20.6 kg, respectively. By the obesity index criteria, $5\%$ of boys and $4\%$ of girls were obese whereas $10\%$ of boys and $9\%$ of girls were underweight. By the Kaup index criteria, $7\%$ of boys and $4\%$ of girls were obese. By the percentage of body fat criteria, $5\%$ of boys and girls were obese. The mean concentrations of serum total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol, Atherogenic Index and serum glucose were 154.1-156.5 mg/dL, 80.1-81.9 mg/dL, 46.8-47.4 mg/dL, 90.9-92.8 mg/dL, 2.34-2.39 and 76.4-77.8 mg/dL, respectively. Serum triglyceride level, AI and body fat percentage of obese children were significantly higher than other children and were significantly lower in HDL-cholesterol level (p < 0.05). In addition there were significant correlation between anthropometric values and serum biochemical indices : Kaup index and obesity index were positively correlated to the systolic blood pressure and diastolic blood pressure in boys and girls (p < 0.01) and to the triglyceride concentration in boys (p < 0.05). These results indicate the need of developing and implementation of nutrition education program for preschool children to prevent further development of childhood obesity and to maintain normal serum lipid profiles.

Nutritional assessment is based on anthropometric, clinical, dietary and biochemical data. There is a lack of studies about the propriety of biochemical indexes for the nutritional assessment in children despite biochemical data in pediatric population are different from them in adult's in many respects. Serum albumin is useful index to evaluate the severity of malnutrition. Hemoglobin and hematocrit tend to decrease in malnutrition on account of defect of iron metabolism and to increase in metabolic syndrome on account of enhancement of erythropoiesis. But, unlike adult, total lymphocyte count is not so useful biochemical indexes in children. We should consider pediatric characteristic when interpret biochemical indexes for nutritional assessment in children, and nutritional status in children should be assessed comprehensively with anthropometric, clinical, dietary and biochemical data.

This study was conducted to investigate the relationship among Rohrer index, and nutritional intake and biochemical status. We examined physical status, dietary intakes, serum cholesterol, blood pressure and other biochemical of children in Taejon. Thin survey was carried out in October, 1995. The subjects were 362 children, aged from 6 to 11 years old. The results were summarized as follows. By Rohrer index, 4.5% of the subjects were lean, 70.2% were normal, 17.0% were overweight and 8.6% were obese. Systolic and diastolic blood pressures of the subjects were 111.73 and 69.88mmHg, respectively. The systolic blood pressure of obese subjects(119.93mmHg) was higher than any other groups. Total cholesterol level was 160.87mg/dl, cholesterol levels in each group were not significantly different. Hemoglobin level of total subjects was 13.10mg/dl, especially hemoglobin levels of 11 year-old girls was lower than that of the same aged boys suggesting that the girls should be supplied with more protein, iron and other nutrients. Energy and protein intakes wee 86.6% and 94.5% of RDA, respectively. The nutrients above the RDA were only two, phosphorus and-vitamin C. The intakes of iron, zinc and vitamin A were lower than 50% of the RDA's. The levels of zinc and niacin were highest in obese group than any other groups. The subjects in overweight and obese groups had eaten more calories from snack and less calories from breakfast than other groups. Rohrer index was correlated with cholesterol, systolic blood pressure and creatinine levels.

Gonadosomatic index, condition index and reproductive cycle with the gonadal development of the female Octopus ocellatus were investigated by histological observations and morphometric data, from January to December, 2000. And changes in biochemical components of the ovary and the trunk tissues including the digestive organ associated with gonadal development were studied by biochemical analysis from January to October, 2001. The specimens were collected at the coastal waters of Buan, Jeollabuk-do, Korea, from January 2000 to October 2001. O. ocellatus is a dioecious organism. The gonad of O. ocellatus locates medially in posterior region of the body. Morphology of the ovary shows round and oval in shape, the average diameter and external colour of ripe ovary was 32 mm and semitransparent light brown in colour. As the ovary was getting mature, transparent elongated eggs covered with chorion were present in the ovarian cavity. Monthly changes in the gonadosomatic index (GSI) showed a similar pattern with those of the condition index. The GSI and condition index began to increase in March and reached the maximum in April. And then, their values decreased from May and reached the minimum in September. Reproductive cycle of O. ocellatus can be categorized into five successive stages: early developing stage (September to December), late developing stage (November to March), ripe stage (March to May), partially spawned stage (April to June), and degenerative/resting stage (June to October). Follicle cells attached to an oocyte were involved in vitellogenesis in the cytoplasm of the vitellogeneic oocyte and formation of chorion (secondary egg membrane) of the ovarian eggs. Spawning occurred between April and June. The spawning period was once a year and the peak took place between May and June. This species belongs to semelparity. According to changes in biochemical contents of the ovary and the digestive organ, monthly variations of moisture, total protein, total lipid and glycogen contents (%) in the ovary showed a negative correlationship with those of the trunk tissues including the digestive organ. Accordingly, it is assumed that the ovary only may be received nutrient supply (total lipid content) for gonadal development from the trunk tissues including the digestive organ (r = -0.55, p < 0.05).

The present study was conducted to investigate dietary habits and biochemical indices according to the obesity index of elementary school students visiting a hospital for diagnosis. The subjects of this study were 150 elementary school students and their mothers. The overweight rates of child subjects were 37.5% for males and 40.9% for females, whereas the rates of underweight children were 35.0% for males and 14.5% for females. Children's obesity index significantly decreased with an increase in the average monthly income of children's families. Children's obesity index, mothers' weights, BMI, and percent ideal body weight were all positively correlated. Blood biochemical values in children (hemoglobin, hematocrit, albumin, globulin, glucose, total cholesterol, and triglyceride levels) and their obesity index also showed positive correlation. For the underweight group, the frequency of iron-deficiency anemia was significantly high, whereas for the overweight group, the frequency of dyslipidemia was high. There was a significant increase in children's obesity index and a decrease in frequency of regular exercise with time spent on the TV/computer. The normal weight group recorded the highest total scores for mothers' nutritional knowledge, whereas the overweight group recorded the lowest total scores. Therefore, to maintain healthy weight in children, nutritional education programs for mothers and children should be developed.

As Korea is expected to become super high aged society in 2026, nutrition is important elements of health in the elderly and affects their life. In epidemiological surveys, anthropometric and biochemical measurements represent important components of nutritional assessment in elderly. In the present study, we investigated anthropometric index, biochemical markers, and nutrient intake for elderly aged over 85 by using data on 71 elderly (24 men, 47 women) over 85 years which was obtained from Korea National Health and Nutrition Examination Survey in 2009. According to BMI values, the prevalence of underweight and obesity was 9.7% and 34.5% in men, and 7.9% and 26.4% in women. The prevalence of sarcopenia was 70.7% in men and 25.0% in women. However, plasma biochemical data are normal range in the older population. In nutrients intake, daily Intake of energy, protein, dietary fiber, water, thiamin, riboflavin, niacin, calcium, and potassium was inadequate considering the Dietary Reference Intakes for Koreans(KDRIs). In conclusion, elderly need to be educated nutrition and their health dietary life to prevent malnutrition, and standard of nutrition intake should be rearranged in elderly aged 85 over considering their antrhopometric index.
