This study was performed to assess the relationship between diet quality and general characteristics, stress, exercise habits, and nutritional knowledge score in the postmenopausal women. The data of dietary intakes were obtained using food frequency questionnaires which were collected from 151 postmenopausal women in urban area. Diet quality was assessed by INQ(index of nutritional quality), MAR(mean adequacy ratio), DDS(dietary diversity score), DVS(dietrary variety score), DQI(diet quality index). The results are summarized as follows. The mean age of the subjects was 59.9 years old. The means of height, weight, and BMI were 154.7cm, 57.2kg and 23.9 respectively. The subjects who did not exercise regularly were 70.9% and those who excercised at least once a week were 29.1%. The subjects who had regular meal time were 69.5% and those who ate breakfast regularly were 72.6%. More than 2/3 of subjects had regular eating behavior. Overall dict quality was significantly(p < 0.05) associated with INQ, MAR, DDS, DQI. However, there was no significant association between income level and diet quality. In conclusion, it would be beneficial to provide nutritional education included dietary diversity, dietary variety, dietary guideline, and adequate flood amount, to prevent chronic degenerative disease and maintain healthful life in the postmenopausal women.

Purpose: This study was conducted to analyze the change in the obesity index in girls receiving a gonadotropin-releasing hormone agonist (GnRHa), based on treatment duration, and to aid in nutritional counseling by investigating dietary habits and lifestyle. Methods: Anthropometric examinations were conducted on 62 girls treated with GnRHa from January 2010 through July 2014. Parents were asked to fill out questionnaires on patient dietary habits and lifestyle. Results: The group taking GnRHa for over 1 year had a higher rate of obesity increase than the group taking GnRHa for less than 1 year, but they had common habits related to obesity, which should be corrected. In addition, 69.2% of the normal weight group taking GnRHa for over 1 year gained weight, and needed more intensive programs, which include physical exercise and nutritional education. Although girls with precocious puberty showed a decrease in the intake of high-calorie foods with nutritional intervention regardless of treatment duration, they still had problems that needed improvement, such as shorter meals and lack of exercise. Conclusion: Girls with precocious puberty and their parents should emphasize maintenance of proper body weight, especially when treatment for over 1 year is anticipated. Consistent education in nutrition, ways to increase intensity and duration of physical activity, and the need to slow down mealtimes are important in managing obesity; doctors need to perform regular checkups and provide nutritional counseling.

Objectives: This study sought to assess the effectiveness of community-based nutrition counseling on improving nutritional status, managing complex chronic diseases, and enhancing the quality of life for elderly individuals with chronic conditions, particularly in older adults with high levels of food insecurity and multiple chronic illnesses. Methods: Thirty elderly subjects with diabetes and hypertension who were registered at local Senior Welfare Center received individualized nutrition counseling, based on their Nutrition Quotient for the Elderly (NQ-E) index. Over a 16-week period, they received tailored counseling and underwent various health and nutritional assessments. The final analysis included 28 participants after two dropped out. Data analysis was conducted using the SPSS v28.0. Results: The subjects were over 70, with multiple chronic diseases including diabetes and hypertension and predominantly female. After 16 weeks, significant improvements were observed in the subjects' grip strength, and HbA1c levels, as well as in their NQ-E scores, indicating improved dietary balance and diversity. There were no significant improvements in the 'Moderation' subdomain of the NQ-E index, suggesting that this aspect requires further attention in nutritional counseling. The subjects' nutritional risk scores (NSI) were also significantly decreased, indicating less nutritional risk. Lastly, as measured by the SF-36K, the subjects' quality of life showed significant improvement in several domains including physical role performance and social function. Conclusions: This study demonstrates that tailored nutrition counseling, based on the NQ-E index, can improve elderly health, manage chronic diseases, and enhance quality of life. This approach potentially broadens the scope of community nutritionists' roles within an aging society. However, additional research is necessary to evaluate these interventions' long-term effects and sustainability.

People with higher genetic predisposition to obesity are more susceptible to cardiovascular diseases (CVDs) and healthy plant-based foods may be associated with reduced risks of obesity and other metabolic markers. We investigated whether healthy plant-foods-rich dietary patterns might have inverse associations with cardiometabolic risk factors in participants at genetically elevated risk of obesity. For this cross-sectional study, 377 obese and overweight women were chosen from health centers in Tehran, Iran. We calculated a healthy plant-based diet index (h-PDI) in which healthy plant foods received positive scores, and unhealthy plant and animal foods received reversed scores. A genetic risk score (GRS) was developed based on 3 polymorphisms. The interaction between GRS and h-PDI on cardiometabolic traits was analyzed using a generalized linear model (GLM). We found significant interactions between GRS and h-PDI on body mass index (BMI) (p = 0.02), body fat mass (p = 0.04), and waist circumference (p = 0.056). There were significant gene-diet interactions for healthful plant-derived diets and BMI-GRS on high-sensitivity C-reactive protein (p = 0.03), aspartate aminotransferase (p = 0.04), alanine transaminase (p = 0.05), insulin (p = 0.04), and plasminogen activator inhibitor 1 (p = 0.002). Adherence to h-PDI was more strongly related to decreased levels of the aforementioned markers among participants in the second or top tertile of GRS than those with low GRS. These results highlight that following a plant-based dietary pattern considering genetics appears to be a protective factor against the risks of cardiometabolic abnormalities.

The purpose of this study was to investigate the anthropometry, biochemical parameters and electrolytes concentrations of the Total Parenteral Nutrition (TPN) patients according to their nutritional status at the time of admission. Thirty-three patients in the Intensive Care Unit at S University Hospital were the subjects of this study. Their nutritional status was classified as At-risk I (Mild PCM, n = 13), At - risk II (Moderate PCM, n = 9) and At-risk III (Marasmus + kwashiorkor + severe PCM, n = 11) . Anthropometeric, biochemical and dietary assessments were performed. The Patients intake of calories (75.02%) and protein (53.15%) was insufficient compare with Korean RDA requirements. The body weight and the Body Mass Index (BMI) in the At-risk III group were significantly lower than in the other groups. The percentage of body weight loss and change of body weight (kg) were significantly higher than in the other groups. The subjects were malnourished as indicated by nutritional related parameters such as serum total protein, albumin, total lymphocyte count (TLC), hemoglobin and hematocrit. Serum total protein, albumin and TLC levels were lower at the time of admission before TPN administration. But after TPN administration, they increased. The electrolyte concentrations did not show any differences following TPN administration. The nutritional status of the patients could be affect by the duration of TPN administration and the number of days of the patients hospitalization. The patients who require nutritional support need the continuous follow-up care and monitoring by a nutritional support team. (Korean J Community Nutrition 8(4) : 574-583, 2003)

The nutritional and health status of low-income alone-living elderly(ALE) was assessed in relation to the activity of daily living (ADL) and nutritional risk factors. One hundred and eighty five ALE over 65 years old, living in the Sungnam area, were interviewed in their homes through questionnaires. The results were as follows : 63.6% of the subjects considered themselves in poor the health and only 4.3% of them considered thermselves healthy. 89.7% of the subjects answered that they were suffering from illness and 29.7% were taking medication. The ADL was assessed through 10 checklist items and the average score of the ADL was $84.78{\pm}11.11$(maximum :100) The nutritional risk index(NRI) was evaluated by 12 risk factors and the average score of the NRI was $4.43{\pm}1.38$ (maximumː12) The scores of the ADL were positively correlated with the scored of the instrumental activities of daily living (IADL)(r=0.7523, p<0.001) and negatively correlated with NRI(r= -0.2694, p<0.001) When subjects were divided into nutritionally high risk group(HNARI: TEX>$NRI{\geq}5$) and nutritionally low risk group(LNRI : NRI<5) according to the USA screening basis, 48.9% of the subjects belonged to the HNRI, But 16.9% of the HNRI and 34.4% of the LNRI belonged to the fourth quartile($Q_{0.75}$) of the ADL, the distribution of which showed significant differences(p<0.05) We suggest that the application of the ADL as a screening tool for nutrition intervention programs for the elderly. Oncemore, further research is needed to develop appropriate checklist items for the ADL and NRI along with the screening basis for the NRI 새 diagnose the adverse nutritional status of the Korean elderly.

Purpose: This study sought to examine whether near total gastrectomy (nTG) confers a longterm nutritional benefit when compared with total gastrectomy (TG) for the treatment of gastric cancer. Materials and Methods: Patients who underwent nTG or TG for gastric cancer were included (n=570). Using the 1:2 matched propensity score, 25 patients from the nTG group and 50 patients from the TG group were compared retrospectively for oncologic outcomes, including long-term survival and nutritional status. Results: The length of the proximal resection margin, number of retrieved lymph nodes and tumor nodes, metastasis stage, short-term postoperative outcomes, and long-term survival were not significantly different between the groups. The body mass index values, and serum total protein and hemoglobin levels of the patients decreased significantly until postoperative 6 months, and then recovered slightly over time (P<0.05); however, there was no difference in the levels between the groups. The prognostic nutritional index values and serum albumin levels decreased significantly until postoperative 6 months and then recovered (P<0.05); the levels decreased more in the nTG group than in the TG group (P<0.05). The mean corpuscular volumes and serum transferrin levels increased significantly until postoperative 1 year and then recovered slightly over time (P<0.05); however, there was no difference between the groups. Serum vitamin $B_{12}$, iron, and ferritin levels of the patients did not change significantly over time, and no difference existed between the groups. Conclusions: A small remnant stomach after nTG conferred no significant nutritional benefits over TG.

In Korea, changes in children's diet patterns accelerate their physical growth and development: frequent snacking has been presumed to be a major cause of increasing dental caries. The present study attempts to clarify the relationship between the physical development of growing children and their tooth decay. For this purpose, 632 six-grade children in 4 elementary school located in Urban(Seoul) and Rural(Po-gok, Yang-In) were classified into three groups based on the Weight Length Index(WLI), known to reflect the nutritional conditions of school-age children, and the relationship was analyzed between each group and the variables considered to be related with dental caries. The result is as follows: The average weight and height of the male is $44.88{\pm}10.89$ kg, $148.49{\pm}7.33$ cm and female is $43.35{\pm}9.60$ kg, $149.23{\pm}6.73$ cm, respectively, which are in the similar level with the Korean Physical Standard. The classification of the children by the WLI reveals a relatively high distribution of over-weighted child ren - 212 persons, 335% of the entire population. The DMFT Index was a little high in the rural area(3.15 teeth in urban and 3.31, in rural). Among the groups of children classified by the WLI, the over-weight group have the highest DMFT index(3.69 teeth). The relationship between the frequency of taking in basic nutrients and the DMFT index is also found: the relationship is not evident in case of the foods containing rich calcium, protein, as well as fruits and vegetables. But, in the protein-rich food, higher frequency of its intake means significantly lower DMFT index in the normal-weight group of the urban children. In case of carbohydrate, higher frequency of its intake means significantly higher DMFT index in all the groups of the rural children. The DMFT index has some correlations with the relevant variables: the index has a positive correlation with the frequency of snacking, and a negative correlation with the economic status. That is, the higher the frequency of snacking is, and the lower the economic status is, the higher the DMFT index may be. In the logistic multiple regression analysis conducted with the presence of DMFT as a dependent variable, only the frequency of tooth brushing is turned to be a variable affecting the presence of either decayed, missing, or filled teeth. Based on the above result, the variables affecting the DMFT index are a time spent on eating, frequency of intake of protein and carbohydrate for a week, frequency of snacking, regular dental check-ups, preventive behaviors for oral health(fluoride gargling, tooth brusing after each meal, proper tooth brushing method). These variables have a relationship with the DMFT index, but the degree is somewhat different between the groups classified either by the region or by the WLI. Therefore, appropriate nutrition management should be conducted according to the individual's nutritional conditions when the services like nutritional education are provided based on the closely-examined characteristics of each target group. And, at the same time, oral health education should be strengthened, and its importance should also be emphasized so that people can pay attention to their own oral health.

The purpose of this study was to investigate the related factors to nutritional supplements intake of elementary school student aged 7 to 12 years in Incheon area. The subjects were 631 mothers of elementary school students and cross-sectional study was conducted by a self-administered questionnaire. In view of the relation with general circumstances, taking nutritional supplements was shown to be significantly associated with general and socio-demographic factors such as father's job, mothers concern about children's academic record, family's monthly income and food cost, and the experience of other family members' taking nutritional supplement. In view of the relation with anthropometric and health-related factors, taking nutritional supplement was associated with elementary school student' weight obesity index, mothers evaluation of children's height and weight mother's concern about health and growth of children, and ,disease of children. In view of the dietary behavior-related factors, taking nutritional supplements was associated with skipping breakfast, food habits, and mothers beliefs and attitude about nutrition and nutritional supplements. However, it was shown that mothers nutritional knowledge did not affect taking nutritional supplements. Therefore, it may be suggested that general and socio-demographic factors, anthropometric and health-related factors, dietary behavior-related factors, and mother's nutritional beliefs and attitude are important determinants in children's taking nutritional supplements.

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.
