Purpose: The purpose of the present study was to investigate the prevalence and lifestyle factors related to the metabolic syndrome in Korean elderly. Methods: A total number of 122 elderly over 60 yr were recruited from a community elderly center. Elderly were classified into young old (60-74 yr) and old (75-84 yr). Metabolic syndrome was defined by third report of the national cholesterol education program (NCEP) expert panel on Adult Treatment Panel III (ATP III). Abdominal obesity was determined by Korean society for the study of Obesity criteria. The nutritional status was measured by mini nutritional assessment (MNA). Results: The prevalence of the metabolic syndrome was significantly higher in the old than young old elderly (p<0.05, respectively). Abdominal obesity and hypertension were the most common risk factors. The related factors to metabolic syndrome were high Body mass Index (BMI) and currently not participating in exercise. Abdominal obesity, low HDL cholesterol and hypertension were associated with specific nutrient intakes. Conclusion: A strategy to decrease the metabolic syndrome in the elderly is urgently needed particularly so for the old elderly. A nutritional and exercise program for young old elders may be helpful reducing the prevalence of metabolic syndrome in later stage.

Cardiovascular disease (CVD) is one of the most common causes of death in elderly Koreans, and HDL-cholesterol is known to have a pivotal role in protecting against CVD. This study was undertaken to study the relationships between plasma HDL-cholesterol levels and dietary, anthropometric, and biochemical factors in elderly Koreans. The 102 subjects, who were over 60 years old, were classified into two groups based on their plasma HDL-cholesterol levels: a risk group with plasma HDL-cholesterol < 40mg/dl in men or HDL-cholesterol < 50mg/d1 in women, and a control group with higher HDL-cholesterol levels. The subjects' mean intakes of energy, calcium, zinc, vitamin A, vitamin $B_2$, vitamin E, and folate did not meet the Korean RDA for elderly people. Vitamin $B_2$ and folate intakes were significantly lower (p<0.l) in the risk group compared to the control group. The consumption of seaweed was significantly lower (p<0.05), and fish intake was 33% lower, in the risk group compared to the control group. Subjects in the risk group showed a higher BMI, waist/hip ratio, triceps skinfold thickness, and % body fat, compared to control subjects. Plasma triglyceride levels and values of the atherogenic index were significantly higher (p<0.00l) in risk group subjects. Significant negative correlations between HDL-cholesterol level and plasma triglyceride level (r= 0.37), and values of the atherogenic index (r=-0.74), were found. In summary, subjects with low levels of HDL-cholesterol were found to have relatively low intakes of vitamin B$_2$, folate, and seaweed, and higher levels of the CVD risk factors: body fat, plasma TG, and AI. These results suggest that plasma HDL-cholesterol levels can be modified by dietary, anthropometric, and hematological means.

This study was performed to develop an index assessing the overall diet quality for Korean. The study subjects consisted of preschool children (PC), elementary school children (EC), high school students (HS), college students (CS), and adults over 30 years old living Seoul and the surrounding areas. The subjects over 30 years old were classified to 30-49 years, 50-69 years, and over 70 years. A dietary survey was conducted using 24-hour recall method and data were collected from 2392 people. Newly developed Korean diet quality index (KDQI) was an index assessing the overall diet quality from the view point of balance. KDQI was based on the nutritional problems of Koreans, dietary risk factors for chronic degenerative diseases, 5 major food groups, and dietary guidelines. The ten components of KDQI were vegetables, fruits, dairy products, dietary variety score, calcium intake, iron intake, energy intake, fat intake, and cholesterol intake. The full score of each component was 10 points and the score of KDQI was calculated by summing the scores of the 10 components. When the KDQI was applied to this study subjects, the distribution of subjects KDQI scores was similar to normal distribution. Mean score of KDQI was 56.0 and the range of the mean by age was from 45.7 for the subjects over 70 years old to 60.7 for the elementary school children. The components which composed the lowest three means were dairy intake, fruit intake, Ca intake in most age groups. Mean score of DVS was one of the highest three but not for the subjects over 50 years old. After subjects with KDQI score over 70 were classified to higher poop and those with KDQI score under 40, to lower group, nutritional characteristics were compared. Energy contributions of carbohydrate, proteins, and fit, percentages of RDA for major nutrients, and dietary diversity scores were more adequate in the higher poop than in the lower group. The lower poop had more risks for chronic degenerative diseases. According to the results, KDQI was valid index to assess the overall diet quality and it could be used to detect risk group for malnutrition and chronic degenerative diseases.

This study examined the effect of viable bifidobacteria and non-digestible carbohydrates on the cecal pH, colonic neoplastic lesion (aberrant crypt) and proliferating cell nuclear antigen (PCNA) labeling index in carcinogen-treated mts. Animals received s.c. injection of dimethylhydrazine (DMH) (15 mg/kg body weight) twice 3 days apart. Three days after the second carcinogen administration, the treatments were begun. 1he treatments were basal diet (AIN-76) with skim milk (Basal/skim), or the following diets with daily gavage of $10^8$ bifidobacteria: basal (Basal/bifido), $2\%$ fructo-oligosaccharide (FOS/bifido), $2\%$ soybean oligosaccharide (SBO/bifido), $2\%$ wheat bran oligosaccharide (WBO/bifido) and $8.4\%$ wheat bran (WB/bifido). After 4 weeks of treatment, cecal pH was measured using a pH probe. The number of aberrant crypt (AC), aberrant crypt foci (ACF) and crypt multiplicity were enumerated and colonic PCNA labeling index was determined using immunohistochemistry. Cecal pH was significantly reduced in SBO/bifido and FOS/bifido groups compared to control group. However, there were no significant differences in either number of AC or rates of cell proliferation as shown by PCNA labeling index among the groups, although mts fed FOS/bifido reduced the numbers of ACF compared to Basal/skim group. The SBO/bifido group did not reduce the number of ACF or PCNA labeling index. Also, other oligosaccharides did not reduce the risk of colon cancer compared to control group. The concomitant reduction of cecal pH and number of ACF suggest that the combination of bifidobacteria and FOS may reduce the risk of colon cancer.

The adequate dietary intake is important to maintain the nutritional status of the patients after pancreatic cancer surgery. This prospective study was designed to investigate the dietary intake and the nutritional status of the patients who had pancreatic cancer surgery. Thirty-one patients (15 men, 16 women) were enrolled and measured body weight, body mass index (BMI), nutritional risk index (NRI), and Malnutrition Universal Screening Tool (MUST). Actual oral intake with nutritional impact symptoms recorded on the clinical research foam at every meal and medical information were collected from electronic medical charts. The rates of malnutrition at admission were 45.1% (14/31) and 28.9% (9/31) by NRI and MUST method, respectively, but those were increased to 87% (27/31) and 86.6% (26/31) after operation on discharge. The median values of daily intake of energy, carbohydrates, fat, and protein were 588.1 kcal, 96.0 g, 11.8 g, and 27.0 g, respectively. Most patients (n = 20, 64.5%) experienced two or more symptoms such as anorexia, abdominal bloating and early satiety. There were negative correlations between C-reactive protein (CRP) levels and the intake of total energy, protein, fat, and zinc. The rates of malnutrition were increased sharply after surgery and the dietary intake also influenced the inflammatory indicators. The results suggested that need of considering special therapeutic diets for the patients who received pancreatic surgery.

Purpose: The purpose of this study was to identify the nutritional status of elderly individuals according to their household types and to investigate the predictors of their nutritional status. Methods: This study, which was a descriptive research study, involved physical measurements, surveys, and biochemical tests in 87 elderly individuals living in the community. Using SPSS/Win 24.0, logistic regression analysis was performed to identify the general characteristics, blood pressure, body mass index (BMI), mini nutritional assessment (MNA) score, and biochemical indicators in elderly individuals according to the household type. Results: Elderly individuals living with family members had higher MNA scores than those of elderly individuals living alone, while showing lower levels of systolic blood pressure and fasting blood sugar. The results of the logistic regression analysis showed that the risk factors were MNA scores (odds ratio (OR)=1.81, 95% confidence interval (CI)=1.36-2.42), systolic blood pressure (OR=0.96, 95% CI=0.92-1.00), and fasting blood glucose (OR=0.94, 95% CI=0.90-0.99). Conclusion: It was confirmed that elderly individuals living alone need differentiated nutrition intervention, since the results showed that they had lower nutritional levels and improper nutritional management than that in elderly individuals living with family members.

Improving dietary patterns, na, in turn, improving nutritional status, is now viewed as a key to improve public health and to prevent chronic diseases. There has been a peat needs to assess diet quality to identify nutritional risk group, however, little research has been done on methods to assess overall diet quality. The purpose of this study was to develope a mini dietary assessment (MDA) index for evaluation of overall dietary quality. A 10-component system was devised based on dietary guidelines and food Tower for Koreans. The system contained 4 food elements of which use is encouraged, such as milk, meat, vegetables, fruits, and 3 food elements of which use is limited, such as fat, salt, or sugar. Also the included were elements on dietary regulation and variety. A subject is to check one of ‘always' 'generally'seldom', which has score of 5, 3, and 1, respectively, so the total possible index score is 50. This index is to use without dietary survey and is to use even by non-nutritionist. A sample of 432 healthy males and females in their 30's and 40's contributed diet intake data based on 24-hour recall for the validation of MDA. The mean MDA score was 31.34 of a possible 50 points. The main nutrients for each MDA component was correlated very well with the results of 24-hour recall. Also, very good correlation was found between healthy eating index (HEI) score and MDA score. However, some of MDA components were needed a modification of term or/and statement. So the Uh was revised and another effort for validation was made with new sample of 169 subjects and even better correlation was found. The revised MDA could be used with minor modification to assess diet quality and to screen nutritional status. (Korean J Nutrition 36(1): 83-92, 2003)

Purpose: Malnutrition affects all age groups, but older adults are particularly more vulnerable to nutritional deficiencies. This study evaluated the age-specific factors affecting malnutrition in hospitalized older adults. Methods: A retrospective study was conducted on inpatient elderly people who received artificial nutrition from 2010 to 2017. Data of demographics, diagnosis, type of nutrition therapy, number of comorbidity, fall risk assessment, Acute Physiologic Assessment and Chronic Health Evaluation (APACHE) score, and intensive care unit admission were collected. Malnutrition was defined as a body mass index (BMI) of less than 18.5 kg/m². Patients were classified as the young-old (65~74 years old), the old-old (75~84 years old), or the oldest-old (85 years old or older). Results: A total of 7,130 older adults were included, and 4,028 patients were classified as the young-old, 2,506 into the old-old, and 596 into the oldest-old. Proportion of malnutrition was higher in the oldest-old compared to the other groups. In multivariate analysis, parenteral nutrition, alcohol, and high risk of falls were factors affecting malnutrition in all groups. Parenteral nutrition and alcohol in the young-old, high risk of falls in the old-old, and male sex in the oldest-old were the factors affecting malnutrition by the age group. Conclusion: Older age was the most significant factor affecting malnutrition. Specific strategies by age are needed to improve nutritional status in hospitalized older adults as influencing factors for malnutrition vary among different age groups.

This study was conducted to recognize the need for diet and nutrition education to correct body-shape and eating habits that lead to eating disorders in college students. The relationship between diet and obesity was confirmed. Approximately 405 (male 46.4%, female 53.6%) students were evaluated by questionnaire in September 2014. The statistical program SAS (ver. 4.3) was used to evaluate the Chi-squared, F and T-value. The correlation between eating disorder risk and eating habits was evaluated by Pearson's correlation. Body type recognition was classified into nine steps up the body fatty (9) to skinny (1) to show their body. Eating disorder risk (KEAT-26) was composed of F1 (attachment factors for weight loss), F2 (attachment factors for binge eating, and food), and F3 (adjustment factor to eating their will. The risk of eating disorders in male 73.4% of low risk, in female 61.3% (p<0.05). According to body mass index, underweight groups recognized in the normal weight (53.7%), normal weight group was in overweight (29.1%) (p<0.001). According to body-type, the overweight group had a higher risk of eating disorders (68.2%). The KEAT-26 showed that the overweight and obese group were high-risk in F1 & F2, while the underweight group was high-risk in F3 (p<0.001). Recognized overweight showed the dangers of eating disorders, proper recognition of body-type and body mass index required. Tendency to seek a balanced diet was associated with eating disorders, no-imposed adequate diet for nutritional education would be made. Proper nutrition education for males is needed depending on the increased incidence of male eating disorders.

The purpose of this study was to investigate the relationship among urn leptin, nutritional status, and urn lipids, glucose of 99 middle school girls residing in Kyluggi-do, Korea. Subjects were assigned to one of three groups such as underweight(BMI < 20, n=38), normal(20$\leq$BMI<25, n=36) and over weight(BMI$\geq$25, n=25) groups. The nutritional status of the subjects was evaluated by anthropometric measurements, questionnaires, 24-hr dietary recalls and blood anal),sis. The results were as follows : The mean age, body weight, height and BMI were 13.93 years, 55.19kg, 158.40cm and 21.96kg/㎡ respectively. The mean menarche age of the subjects was 12.64 years and the mean daily energy intake was 94.22% off RDA for Koreans. The energy ratio from carbohydrate fat and protein was 63: 24: 13. Underweight group showed the lowest intakes of oils and fats among three groups(p<0.05). The mean serum levels of leptin, glucose, total cholesterol, HDL-cholesterol. LDL-cholesterol and triglyceride were 10.57ng/ml 78.80mg/dl, 12.29mg/dl, 48.07mg/dl, 93.50mg/dl and 78.61mg/d1, respectively. The mean atherogenic index was 2.37. There were significant increases in serum leptin, glucose, LDL-cholesterol, triglyceride and atherogenic index of subjects with increases in their BMIs. Serum leptin showed a significantly positive correlation with BMI(p<0.001), body fat percent(p<0.001). When BMI was adjused, serum leptin showed a significantly positive partial correlations with intakes of animal protein(p<0.05), milks and animal foods(p<0.05), Serum leptin showed a significantly positive correlation with serum glucose(p<0.05) total cholesterol(p<0.01), LDL-cholesterol(p<0.001), triglyceride(p<0.001) and atherogenic index(p<0.001), however, it had significantly negative correlations with HDL-cholesterol(p<0.05). Therefore, these results suggest that the increase of serum levels of leptin may elevate the risk of cardiovascular disease and lipids and some nutrient intakes may be related with serum leptin levels.
