This study was conducted to find out the most suitable weight-height index out of the $weight/height^{p}-type$ indices that could be used for the evaluation of nutritional status in an epidemiological survey and for the screening of the obesity. The subjects were chosen randomly, 2,182 males and 719 females from college students and office workers in Seoul districts. The 'best' power-type weight-height index for Korean men and women of all ages from 16 to 59 was found to be $weight/height^{1.54}$ for males and $weight/height^{1.42}$ for females. $Weight/height^2$ (Kaup index), however, was the best suited weight-height index for each age group of both sexes except that relative weight (weight/height) was considered to be desirable to apply for males of teen-aged and of over fifties and for females of over forties of age. Normal ranges of Kaup index values for males and females of each age group were presented in tables 5 and 6. These findings suggest that Koreans are generally leaner than other ethnic groups of the same sex and age.

Objectives: Human papillomavirus (HPV) infection is highly associated with cervical cancer. So, the modification of the risk factors of HPV infection is essential for prevention of cervical cancer. This study was performed to evaluate the risk factors of HPV infection. Methods: HPV test of 12,337 study population conducted using Hybrid-Capture II assay(HC-II) and self-administered questionnaires were collected. The study population was people who visited hospital-based medical screening center from January to December 2007 and all were female employees or employees' partner. Results: In logistic regression analysis, smoking and alcohol drinking were significant factors, with odds ratios of 1.328 (95% CI 1.010~1.746) and 1.644 (95% CI 1.309~2.066), respectively. Nutritional supplements was also significant factor, which odds ratio was 1.161 (95% CI 1.004~1.343). Oral contraceptives was positive association with HPV infection (odds ratio 2.108; 95% CI 1.217~3.652), whereas condom was negative association (odds ratio 0.851; 95% CI 0.740~0.979). Conclusion: HPV Prevalence of 12,377 study population was 11.4%. Smoking, alcohol drinking, nutritional supplements and oral contraceptives were possible risk factors of HPV infection, and condom had possible preventive effect on HPV infection. Further prospective and comprehensive studies about HPV risk factors are required.

One hundred and fifty four micro algal strains, newly isolated from nationwide freshwaters in Korea, were screened for their anticancer, ant diabetic, and antibiotic activities. The micro algal strains were cultured with different nutritional conditions that were divided into 4 groups as follows; a normal Allen medium, nitrogen (N)-limited medium, phosphorus (P)-limited medium, and N and P-limited medium. Algal biomass was extracted with a mixture of acetone:H₂O (1:1, v:v) and the extracts were used for the screening of bioactive materials. Anticancer, ant diabetic, and antibiotic materials were screened by the methods of vaccinia Hl-related protein tyrosine phosphates (VHR DS-PTPase) inhibition, protein tyrosine phosphates 1B (PTP1B) inhibition, and paper disk. The inhibition activity of VHR DS-PTPase was observed in 18 strains, having a maximum 79% inhibition from Anabaena affinis and the inhibition activity of PTP1B was observed in 9 strains, having a maximum 97% from Sphaerocystis schroeteri. Microcystis aeruginosa incubated in an N and P-limited medium showed antibiotic activity in 8 species out of 13 pathogenic bacteria. As a whole, it seemed that the stressed condition such as N and/or P limitation increased the production of bioactive materials in micro algae.

The purpose of this study was to investigate the status of clinical nutrition services at various medical centers in Seoul, Korea. A questionnaire was distributed to the departments of nutrition at 44 hospitals in Seoul on July 2009. Nutritional screening carried out at a rate of 59.1% at the medical centers, and a significant difference was found according to the type of center, from 100% in tertiary hospitals to 18.8% in normal hospitals. On annual average, the numbers of inpatients, inpatients for malnutritional screening, inpatients with malnutrition, and inpatients for malnutrition management were 15,169.5, 10,870.9, 2,224.8, and 1,546.2, respectively. On average the group nutrition education was done 36.1 times/year for diabetes, 8.2 times/year for cancer, and 1.9 times/year for renal disease, and the numbers of participants 423.1, 95.1, and 31.5, respectively. On average the individual nutrition education of inpatients with diabetes was done 135.4 times/year for ordered-type, and 119.3 times/year for unordered-type, 106.2 times/year for paid-type, and 148.5 times/year for unpaid-type. The mean fee for education and counseling was the highest for peritoneal dialysis (73,090.9 won) but the lowest for heart disease (23,609.1 won). On average the individual nutrition education of outpatients with diabetes was done 234.6 times/year for ordered-type, and 2.5 times/year for unordered-type, 204.4 times/year for paid-type, and 32.7 times/year for unpaid-type. The mean fee for education and counseling was also the highest for peritoneal dialysis (63,500.0 won) but the lowest for heart disease (21,336.4 won). To implement more effective clinical nutrition service, a national medical insurance imbursement policy should be urgently instituted such that diseases left as unpaid are covered by health insurance, including all nutrition-related disease.

This study was performed to identify association between nutritional status and health risks of the elderly. This was a cross-sectional study involving low income elderly women in Gwangju, Korea (${\geq}$65y, n = 92). Socio-demographics, life style characteristics, health conditions, dietary intakes based on 24h-recall method, anthropometric measures, and clinical biochemistry parameters were examined. Anthropometric and clinical parameters included wt, ht, waist, hip, body protein, body fat, abdominal fat, total cholesterol, HDL-cholesterol, triglyceride, total protein, albumin, hemoglobin, hematocrit, fasting blood glucose, ferritin, IL-2, IL-6, TNF-${\alpha}$, CRP, TAS, TBARS, systolic blood pressure, and diastolic blood pressure. The subjects were divided into three groups based on age (65-74y, 75-84y, 85y${\leq}$) and were divided into two groups according to the sum of the Nutrition Screening Initiative (NSI) checklist score (adequate nutritional status, NSI score ${\leq}$3; at risk of malnutrition, NSI score >3). Mean and frequency of variables were estimated. Analysis of Variance, Tukey test, Chi-square test, and Multiple linear regression analyses were performed. Mean BMI and body fat were 25.1 $kg/m^2$ and 40.0%, respectively. However, for over 80% of subjects, the intakes of energy, fiber, thiamin, riboflavin, niacin, folate, Ca, K, and Zn were less than the Korean DRI (EAR or AI). The subjects who had lower NSI score tended to have better health status, eat meals frequently, have less depression, and exercise regularly. The subjects who had higher NSI score tended to have tooth problems, to eat alone most of time, and to be physically unable to cook or feed. Serum IL-6 and TNF-${\alpha}$ were significantly related with nutritional status which suggested higher tendency of inflammatory response. Serum IL-2, TAS, and glucose were significantly correlated with body fat (%) or abdominal fat (%). These results suggest that improving the nutritional status, increasing regular exercise, maintaining normal weight are beneficial to health care of low income elderly women.

This paper describes in detail proximate composition, nutritional profile, phytochemical constituents, antioxidant activities, antimicrobial potential, and antihemolytic activity (towards human erythrocytes) of various fractions of wild Ganoderma lucidum. Proximate analysis established that wild G. lucidum comprises about $87.02{\pm}5.45%$ of moisture, and the remaining part is a rich source of proteins ($8.59{\pm}0.37%$), crude fiber ($54.21{\pm}1.2%$), and carbohydrate (35.16%) with smaller fat content (3.33 %). Similarly, phytochemical screening revealed the presence of flavonoids ($217.51{\pm}0.30mg/g$), ascorbic acid ($116{\pm}7.32mg/g$), phenolics ($360.72{\pm}34.07mg/g$), ${\beta}$-carotenes ($0.42{\pm}0.04{\mu}g/g$), and lycopene ($0.05{\pm}0.00{\mu}g/g$). Extracts of wild G. lucidum in various solvents provided first line protection against Escherichia coli and Pasteurella multocida in the order of ethyl acetate> ethanol> methanol> n-hexane> water. Furthermore, aqueous and methanolic extracts of wild G. lucidum were found to be safe towards human erythrocytes. Overall, wild mushroom (G. lucidum) was found to be a good source of dietary supplements, antimicrobial and antioxidant agents in the pursuance of its commercial utilization in food and pharmaceutical industries.

This study was performed to evaluate effects of dietary variety scores (DVS) and dietary diversity scores (DDS) on the nutritional quality of the diets of Korean college students, and to examine the association between food group intake patterns and nutritional adequacy. This study examined the relationship of dietary diversity scores (DDS), dietary variety scores (DVS), and food group intake patterns with nutrient intakes using 24-hour recall data (n=.358). The .DDS was calculated from the sum of each of the five food groups consumed as a score of 'I'. DVS was determined by counting the number of food items consumed daily. Food group intake patterns were expressed with the presence or omission of five major food groups-dairy, meat, grain, fruit, and vegetable. The four most prevalent food group patterns and the proportion of the population reporting them were as follows; no dairy and fruit, $23\%;\;no\;dairy,\;20\%;$ no dairy, meat, and fruit, $15\%$; all food groups, $14\%$. Even though the DDS or DVS was higher, the majority of this study population failed to meet the Korean RDA for calcium in both genders and iron in women. Higher DVS scores $(\geq31)$, within all DDS groups, were associated with the largest proportion of individuals consuming more than $75\%$ of the Korean RDA for selected nutrients. The consistency of these results indicates that screening diets to evaluate the overall dietary variety and variety among the major food groups including food group intake patterns provide meaningful information about their quality.

Purpose: Iron deficiency remains a very common nutritional problem despite the improvement in nutrition and increased understanding of methods for its prevention. Thus, we try to create a new method for screening iron nutrition through infant nutrition history. Methods: Among the children who visited Inha University Hospital from March 2006 to July 2012, 181 children with iron deficiency anemia (IDA) and 52 children without IDA ranging from 6 to 36 months of age were reviewed in this study. We used the age when they began to wean food, the type of sort weaning foods, the time required for successful weaning, iron content in weaning foods, and the duration of breastfeeding for scoring infant nutrition history based on a questionnaire. Results: The mean score of the IDA group was $7.8{\pm}2.6$ points, which was significantly higher than that of the control group ($5.6{\pm}2.1$) (p=0.000). If we set up the cutoff value at 6 points, this screening has 86.8% sensitivity and 36% specificity. In addition, as the IDA score increased, there was a falling trend of hemoglobin. Conclusion: The IDA score does not have high specificity or high sensitivity. However, this study conveys that those patients who record a high score have low hemoglobin. Therefore, we suggest this score system for screening more IDA patients via nonpainful techniques.

Purpose: The aim of this study was to determine the effects of nutritional intervention focused on a Nutrition Support Team (NST) in patients receiving enteral nutrition (EN) in general hospital wards. Methods: The electronic medical records of 95 adult patients admitted in C university hospital and received EN supply for more than 3 days at a general ward were analyzed retrospectively. The subjects were classified into the intervention group (n = 40) and non-intervention group (n = 55). Results: The calorie support rate (%) and protein support rate (%) increased significantly only in the intervention group after 2 weeks compared to the rate upon admission. The serum albumin levels increased in the intervention group after 2 weeks compared to the levels at admission, but decreased in the non-intervention group. The glucose levels decreased only in the intervention group compared to that at admission. Conclusion: The nutritional status of the patients was improved by the proper planning of nutrition management from the beginning of hospitalization and systematically managing the nutrition intervention of the NST.

This study was conducted in order to identify the relationship between psychological factors, such as depression and self-esteem, and nutritional status, such as nutritional risk index and nutrient intake, among the elderly in Chunnam Province. The participants were 119 elderly individuals over the age of 65 years who visited the Senior Welfare Center in Chunnam province between January 29 and February 2, 2007. This study was conducted using a structured questionnaire that included, the Center for Epidemiologic Studies Depression Scale (CES-D), General Self Efficacy Scale (GSES), Nutritional Screening Initiative Checklist (NSI checklist), questions pertaining to the general characteristics of the participants and an estimation of nutrient intake using the 24-hour recall method. Data were analyzed by the SPSS program. Analysis of the participant's CES-D scores revealed that 43.7% of the subjects were normal and 56.3% had more than mild depression. The mean GSES score was 45.9 for the entire group of subjects (51.9 for men, 43.6 for women). The mean nutritional risk index value was 4.30 (5.03 for men, 4.01 for women). Analysis of the participant's scores on the NSI checklist revealed that 69.7% of the subjects were normal and 30.3% exhibited a moderate nutritional risk. The CES-D was positively correlated with the NSI checklist (p < 0.05) but negatively correlated with nutrient intake. However, the GSES was negatively correlated with the NSI checklist (p < 0.05), but positively correlated with nutrient intake (P < 0.01 for protein, calcium, phosphorus, zinc etc.). The results of this study indicate that it is necessary to manage psychological factors, including depression and self-esteem, in the elderly in order to decrease their nutritional risk and increase their nutrient intake.
