Purpose: The purpose of this study was to investigate the health status, nutritional status, and nutrient intakes of Korean female elderly who are members of a local church in Seoul, Korea. Methods: The subjects were 59 female who are aged >65 yr. We investigated the nutritional status of the subjects using anthropometric and biochemical measurements. Interview was conducted to obtain the information regarding the health status. We also obtained dietary intake of these subjects to figure out the nutrient intakes. Results: The mean age of the subject was 74.0 yr old. Based on the WHO standard (obesity, body mass index, BMI ${\qeq}25$), we categorized the subjects to the obese and the non obese groups. The number of subjects in the obese group was 34 (57.6%). The mean Diastolic BP (p=.002), BMI (p<.001), waist circumference (p<.001), hip circumference (p<.001), blood level of transferrin (p=.038), and nutrient intakes of calcium (p=.026), potassium (p=.046), folate (p=.038) and vitamin E (p=.031) were higher in the obese group than in the non obese group. The subjects with hypertension was 67.5%. The presence of hypertension was correlated with BMI (p<.05). The number of subjects with hypercholesterolemia was 17 (28.8%). The level of cholesterol was correlated with BMI (p<.05) and wasit/hip ratio (p<.05). Conclusion: The female elderly in our study had higher prevalence of obesity which is a risk factor for hypertension and hypercholesterolemia. The nutrient intake of high sodium, high cholesterol, and low dietary fiber of these subjects suggests that there is an urgent need to develop an well planned nutritional education program for female elderly.

This study sought to determine changes in self-selected diets in response to a high energy tomato pasta entree. Thirty men, mostly African-American, who were diagnosed with prostate cancer and also scheduled for prostatectomy were enrolled in the study. Dietary intakes were obtained by 24 hr diet recall for 3 days before the intervention and 3 days in week 2 during the intervention. Tomato pasta entrees were formulated to contain 30 mg of lycopene with roughly the same macronutrient composition and averaged 771 kcal/entree. Mean adherence to lycopene dose was 82% and, days when the entree was consumed, the mean adherence to lycopen was 90%. Lycopene intake in their self-selected diet decreased from 5 to 1 mg/day which lowered the exposure to lycopene, planned during the intervention. The men were able to decompensate for most of the added energy to their diet, but there was still a mean increase in total intake of 242 kcal/day (p=0.04), which did not result in weight gain over the short period of the study. There were no significant changes in the percent of energy from protein, fat or carbohydrates, but dietary cholesterol increased from 341 to 472 mg/day (p=0.0002). Mean intakes of vitamins A and C, and folate were not significantly different and were above the EAR. Vitamin E intake decreased, but, because of the variance in intake, the decrease was not statistically significant. Possible deterioration of diet quality should be a consideration when recommending whole food interventions for the prevention of chronic disease or the amelioration of physiological dysfunction.

The study purpose was to examine which factors including health perceptions & behaviors, psychosocial factors, dietary intakes were different by stages of change to reduce fast food consumption among university students. Survey data(n = 341) were analyzed using X$^2$ test or analysis of variance. With respect to stages of change, $17\%$ were in the precontemplation ; $21.4\%$ for contemplation, $19.7\%$ for preparation, 11.7% for action, and $30.2\%$ for the maintenance stage. Frequency of fast food consumption (p < 0.001), health status, interest toward health, and exercising behavior (p < 0.05) differed significantly by stages of change. Demographics and nutrient intakes, however, had no association with stages of change. Those in precontemplation through preparation stages felt more strongly on the advantages such as taste, satiety, cleanness of restaurants (p < 0.001), and diverse menus (p < 0.05). Compared to maintainers or actors, pre-contemplators agreed less to the disadvantages of eating fast foods, including sanitary problems (p < 0.001), overeating, indigestion, decreased vegetable intakes (p < 0.01) and loss of freshness (p < 0.05). Influence of significant others (e.g., friends, siblings, parents) significantly differed by stages of change. Compared with maintainers, those in preaction stages felt less control over facilitators or situations for fast food consumption. These included 'others like fast foods', 'providing standard meals', 'when I don't have foods for meals'(p < 0.001), availability, advertisement, 'socially popular', 'when I feel hungry'(p < 0.01), and 'when I don't like to prepare meals' (p < 0.05). These results suggested that nutrition education be planned considering one's stages of change for fast food consumption. For those in preaction stages, it is desirable to use motivational strategies to increase benefits and remove barriers of change, and help to develop skills to deal with situations or factors for fast food consumption. The support from friends or families is also needed to move to further stages.

This study was done to investigate the 12 college volleyball player's food behavior, nutrient intakes, and their serum lipid levels during the periods of training and detraining and to provide basic data for an effective program for the volleyball players during the period of detraining after the game season. The results were summarized as follows : The total daily energy intake of the players was $3,363{\pm}339kcal and 3,692{\pm}499kcal$ during the periods of the training and detraining, respectively. During the training period, daily intakes of protein, calcium and vitamin A, and $B_2$ were lower than the recommended dietary allowance for the players. During the detraining period, the players' daily intakes of calcium, iron, and vitamin A were even lower. However, the consumption of alcohol was dramatically increased during the period of detraining. The levels of serum triglyceride and very low density lipoprotein were significantly increased during the detraining period. Basal metabolic rates were significantly increased after the training period and diastolic pressure was decreased during the detraining period. In conclusion, out results suggest that the detraining of volleyball players for 10 days after intensive training, negatively affects their food behavior and serum lipid concentrations. Therefore, for the improvement of performance for the next game season, a planned program for the players' detraining period should be developed.

The purpose of this study was to investigate whether nutrition counseling could lead to a beneficial outcomes in patients with cardiovascular disease(CVD). Fifty CVD patients(23 men and 27 women) participated in a dietary counseling program which was based on serum lipid management. Various markers of disease risk including lifestyles, anthropometric indices, eating behaviors, serum lipids, antioxidants, lipid peroxides were measured before and after the program. The program lasted 3-11 months depending on individuals. Waist/hip ratio decreased after nutrition counseling only in women. Smoking and alcohol drinking status did not change significantly after counseling. Food habit score increased significantly in both men and women(p<0.05), and patients consumed mixed cereal rice, fruits, seaweeds, legumes more frequently and snacks less frequently after nutrition counseling (p<0.05). Although intakes of energy, carbohydrate and vitamin B1 were reduced significantly after nutrition counseling, nutrient densities of calcium and iron of diets have increased significantly after nutrition counseling, and those of other micronutrients were not different Serum total cholesterol decreased significantly in men and LDL cholesterol decreased significantly in women. In women lipid peroxide level decreased and $\alpha$-tocopherol level increased significantly, while there was no significantly change in men. We conclude that well-planned nutrition counseling would reduce risks of cardiovascular disease through improving dietary behavior, lipid profile and antioxidant status.

Cardiac valve allografts have been used as replacements for diseased valves and right ventricular outflow tract reconstruction, the long term follow-up of which has been reported satisfactory. For a good long-term result, it is essential that the allograft be viable at implantation. In this study, we aimed at preparing the cardiac valve allografts aseptically, preserving them at cold- and cryo-conditions, and testing the viability of the allografts after preservation by four methods. We tested the viability of the cardiac valve allografts preserved in cold refrigerated state[4$^{\circ}$C in nutrient media & in liquid nitrogen tank[cryopreservation under -149$^{\circ}$C for pre-planned time periods. The testing methods were 1 glucose utility test 2 tissue culture 3 thymidine uptake test and 4 histologic evidence by light microscopy. We observed no differences in the viability between cold- & cryo-groups and similar results among the methods for testing the viability. In conclusion, there was no difference in the viability between cold- and cryopreserved-allografts at least for 14 days of preservation. And glucose utility test and thymidine uptake test were satisfactory in the evaluation of the allograft viability, since they were easy and rapid with relatively quantitative results.
