The study compared eating and physical activity related behaviors and self-esteem between healthy weight and obese children by presenting 175 primary school students in Busan City and Gyeongsang province with a self-reported questionnaire and Coopersmith's self-esteem inventory. The questionnaire was composed of 25 items, weighted primarily by a Likert scale. The self-esteem inventory presented to the students comprised 25 'Yes' or 'No' response questions to different statements. The study found obese children were more likely to think they always had to control their weight (p=0.000), reportedly measuring their weights significantly more than the healthy weight children. Also the study found that obese children are significantly more likely than healthy weight children to go on a diet, however neither group were successful in losing weight as the duration of the diet in 79.5% of the total sample lasted no longer than one week. In comparison to healthy weight children, obese children reported that they consumed fewer snacks during the day, avoided snacking subsequent to an evening meal and exercised more frequently for as long as physically possible. Interestingly, we found no difference of reported self-esteem between groups, though the obese group were more likely to answer that their parents did not understand them (p=0.055) Based on these findings, we concluded that the obese children who participated in the study were more aware of their body weights than the healthy weights children. It may be necessary to investigate further the relationship between self-esteem and participants' weights while considering other variables such as personality and body image.

The present study conducted to examine the effects of proteins from different sources on Ca excretion in 6 healthy young adult Korean women. The subjects were given meat protein diet for 5 days and soy protein diet for subsequent 5 days. the two diets were similar in protein and Ca contents. Urinary and fecal samples were collected for the last 2 days of each diet period and were analyzed for Ca and P. The results were as following ; 1) Mean daily urinary calcium excretion was 126.5$\pm$22.70mg for meat protein diet and 83.7$\pm$17.19mg for soy protein diet and the difference was significant (P<0.025). 2) Fecal Ca excretion did not show significant difference between two experimental preiod ; 466.9$\pm$73.68 mg of meat portein diet 284.4$\pm$54.96mg for soy protein diet. 3) Three out of six subjects showed negative balance on meat protein diet, but only one showed negative balance on soy protein diet. The averageof the balances on meat protein diet was -65.4 $\pm$68.19 and that of soy protein diet was 155.3$\pm$52.28 ; the difference was significant(P<0.025). 4) Urinary P excretion tended to be higher on meat protein diet but was not significant compared to soy protein diet . Fecal P excretion was significantly higher (P<0.001) on soy protein diet. Overall P balances for meat protein diet and soy protein diet were 219.94 mg and 229.46mg respectively (P<0.05). The above results show that urinary Ca excretion was significantly higher on meat protein diet but fecal excretion did not show significant difference between meat protein diet and soy protein diet. The overall Ca balance was significantly higher on Soy protein diet compared to meat protein diet.

This study was performed to evaluate the validity of the food frequency questionnaire (FFQ), which is being used at the Samsung Medical Center. In total, 305 (190 males and 115 females) participants consented and completed the 3-day diet records and FFQ. Age, gender and energy-adjusted and de-attenuated correlations ranged from 0.317 (polyunsaturated fatty acid) to 0.748 (carbohydrate) with a median value of 0.550. The weighted kappa value ranged from 0.18 (vitamin A) to 0.57 (carbohydrate) with a median value of 0.36. More than 75% of the subjects were classified into the same or adjacent quartiles. The FFQ had reasonably good validity compared with that of another study. Therefore, our FFQ is considered a proper method to assess nutrient intake in healthy Korean adults.

Asian Americans is a minority population contributing approximately 4% to the total population of the United States, however it is one of the fastest growing populations. Although Asian Americans as a group have socioeconomic profiles that are similar to white Americans, significant variations exists within and across Asian ethnic groups. The top ten leading causes of death for Asian Americans includes cancer, heart diseases, stroke, unintentional injuries, diabetes, influenza and pneumonia, chronic lower respiratory disease, suicide, nephritis, and septicemia. The prevalence of obesity is lower among Asian Americans, however this should be taken with considerations specific to Asians. High salt and low calcium consumption seem to be dietary risk factors for Asian Americans, although dietary patterns are changing with acculturation. Factors affecting dietary patterns are discussed in this paper. A proactive nutrition education approach for Asian Americans should be promoting maintaining 'healthy' aspects of ethnic diets and adopting 'healthy' American diets. Collaboration with nutrition educators in Asian countries would be helpful to overcome limited resources available for researching and developing nutrition education messages and materials for Asian Americans.

Traditional Chinese cuisine, which is highly evaluated with respect of taste and techniques, is built based on a sound healthy philosophy and distinct dietary culture, with emphasis on the unity of human beings and nature. The traditional cuisine utilized food materials according to the physical status and seasons, which is still a valuable principle in the modem diet. According to relevant research, the nutrient retention in Chinese cooking is acceptable. However, following the rapid growth of domestic economy, the Chinese diet is in danger of losing its original merits, especially when eating out. The excessive desire for food enjoyment leads to a rapid increase in the prevalence of obesity and chronic disease. It is a critical point to review the characteristic of traditional Chinese cuisine and lead the trend to a healthy direction.

Purpose: To explore what particular types of information were important to patients diagnosed with cancer. Methods: Seventy three patients with cancer at an outpatient clinic and hospitalized patients in W Christian Hospital Korea, responded. The structured questionnaire developed by the investigator based on previous studies. Results: There was a significant negative relationship between age and the score of informational need (r=-.307, p<.05). Level of education, and level of monthly income were related to level of informational need. The top three informational priorities according to the time since diagnosis were 'Self care during treatment', 'Health food and diet', 'Likelihood of recurrence', 'Follow up care' and 'Side effects'. The top three informational priorities for patients with breast cancer were 'Likelihood of recurrence', 'Metastasis possibility', 'Treatment options', and 'Side effects. For patients with stomach cancer, they were 'Follow up care', 'Healthy food and diet', 'Likelihood of recurrence', and 'Metastasis possibility', and for patients with colon/rectal cancer, they were 'Side effects', 'Healthy food and diet', 'Likelihood of recurrence', and 'Self care during treatment'. Conclusion: The assessment of information needs based on demographic factors and disease-related factors is critical in helping patients with cancer to manage their illness.

Purpose: The purpose of the study was to investigate factors that influence university women with eating problems. Methods: Study participants were 307 women from two universities. Self-report questionnaires which included items on eating problems, satisfaction with body shape, self-esteem, body mass index, and weight control methods were used. Data were analyzed using independent t-tests, ${\chi}^2$ tests, and a multiple binary logistic regression. Results: About 20% of the undergraduate women were experiencing eating problems. The problematic eating group showed more dissatisfaction with body shape than the normal eating group, and used more diets, fasting, diet-products, and uretics/laxatives to control body weight. Significant predictors for the problematic eating group were diets, diet-products, BMI, self-esteem and dissatisfaction with body shape. The strongest predictors were diets; risk for women university students who had been on a diet was 15 times higher than their counterparts. Conclusion: It is pertinent for health professionals to start intervention programs to educate university women with eating problems. The contents should include information on healthy weight control methods, improving satisfaction with body shape and self esteem, as well as creating social atmosphere about healthy body shape for women.

This study was performed to investigate the effects of HBM(Healthy Body Maker) on the weight loss and serum cholesterol level of rats. Twenty male Sprague-Dawley rats weighing 200$\pm$5g were grouped into 2. Rats were raised for 6 weeks with diet containing 0% and 5% of HBM. 1. There were no clinical signs for all the experimental period(6 weeks) in 0% and 5% groups. 2. At 3 and 6 weeks. body weight of 5% HBM group was significantly lower than that of control group. respectively(p<0.05, p<0.01). 3. At 4 weeks. the level of MCHC of 5% HBM group was significantly higher than that of control group(p<0.01) And at 6 weeks the level of RBC and Hct of 5% HBM group were significantly higher than those of control group(p<0.05) 4. At 6 weeks. the level of serum cholesterol of 5% HBM group was significantly lower than that of control group. 5. Absolute liver weight of 5% HBM group was significantly lower than that of control group(p<0.05). 6. Minor subaceous sickness of liver cell in the control group appeared but no symptom of liver cell in 5% HBM group. It is concluded that HBM was a safe and effective diet food which aided in inducing weight loss in rat without any observed harmful clinical side effects.
