Background & Objectives: Self-rated health has been widely used to evaluate health status and accepted as a subjective measurement of quality of life. This study aimed to analyze the associations between self-rated health, health promotion behaviors, and mental health factors and suggest the approaches to improve health status among university students. Methods: Two thousand six hundred seventy-seven students who had stayed at dormitories on campus participated in the DU health survey by self-reported questionnaire from April 10 to 14, 2017. Multivariate logistic regression analysis was performed to estimate the odds ratios and 95% confidence intervals of association of self-rated health with health-related factors among male and female students. Results: 38.6% of the respondents reported good self-rated health. Male and first-year students were more likely to report good self-rated health than female and third-year students. There were significant differences in sex, grade, health problems, BMI, sleeping hours, eating breakfast, consumption of fruits and vegetables, physical activity (regular walking, strength exercise, moderate exercise, vigorous exercise), perceived stress, depression, and suicide thought (p<0.05). Conclusion: Although health promotion programs for university students are essential to support their adaptation to campus life and academic achievement, evidence-based health programs to encourage their participation are still insufficient. Therefore, it should establish a campus-based health policy and develop health promotion programs to increase self-rated health levels and prevent mental health problems for university students.

에리스리톨은 4탄당의 당알코올에 해당되며 포도당을 원료로 효모에 의해 생산되는 발효 감미료제로 버섯, 포도주, 과실류, 청주, 간장 등의 발효식품에 함유되어 있는 천연당이다. 에리스리톨과 다른 감미제에서 Streptococcus mutans (S. mutans)의 glucosyl transferase (GTF)와 fructosyl transferase (FTF)의 유전자 발현 양상을 확인하여 치아우식 예방을 위한 제품을 생산하거나 활용 시 올바른 정보와 기초자료를 제공하고자 시행하였다. 연구결과 에리스리톨은 치아우식에 관여하는 S. mutans의 생육을 억제하는 것으로 나타났으며 자당(설탕) 대체 감미제로서 우식예방 효과가 우수한 것으로 확인이 되었다. 특히 세포외다당류 합성에 관련된 gtf B, gtf C, gtf D, ftf 의 발현이 낮게 나타나 세포외부에 다당류의 합성을 억제하여 치면세균막 형성과 치면에 세균의 부착률을 감소시킬 수 있을 것으로 생각된다. 따라서 Streptococci에 의한 우식기전에 에리스리톨이 효과적으로 항우식 감미제로서 사용될 수 있다고 생각된다.

Patients with colorectal cancer may experience symptoms such as diarrhea, nausea, and anorexia, during surgery and chemotherapy, which can increase the risk of malnutrition. In addition, dietary habits play a key role in the onset of colorectal cancer; therefore, it is necessary to improve dietary habits to prevent recurrence during treatment after diagnosis. In this study, a clinical nutritionist conducted 4 interviews for patients diagnosed with colorectal cancer and scheduled for colectomy: before surgery, after surgery, 1st chemotherapy, and 2nd chemotherapy, and provided nutrition care for each treatment course to determine its effects on nutrition status and disease prognosis. Significant weight loss but no decrease in muscle mass was observed during treatment. Body fat mass, although not statistically significant, showed a decreasing tendency. The percentage of people who responded 'yes' to the below items increased after compared to before receiving nutrition education: 'I eat meat or eggs more than 5 times a week,' 'I eat seafood at least three times a week,' 'I eat vegetables at every meal,' 'I eat fruits every day,' and 'I eat milk or dairy products every day.' These results indicate that the patients changed their dietary habit from a monotonous eating pattern to a pattern of consuming various food groups after receiving nutrition education. These results suggest that continuous nutrition care by clinical dietitians, according to the patient's treatment process, can help improve the patient's nutritional status and establish healthy eating habits.

This study was done to evaluate the antioxidant status of female college students by determining their intakes and plasma levels of antioxidnt vitamins (vitamin C, A and E) and total antioxidant status (TAS). Subjects were 46 healthy female college students aged 20 - 29 years. Body composition was determined by a multifrequency bioelectrical impedance analysis. Dietary intakes were examined by 24hr record method and nutrients intakes were analyzed by the Computer Aided Nutritional analysis program for professional (CAN-pro). Plasma vitamin C level were measured by spectrophotometric method and retinol, ${\beta}$-carotene, ${\alpha}$-tocopherol were measured by HPLC. Plasma TAS was measured with a Randox kit using the trolox equivalent antioxidant capacity (TEAC) method. Daily energy and protein intakes of the female college students were 1670.5㎉ (83% of RDA) and 63.3g (115.1% of RDA), respectively. However their intakes of Ca and Fe were below 75% of RDA. Their intakes of vitamin A and C were 596.6 ${\mu}$ gRE (85.2% of RDA) and 71.0mg (101.4% of RDA), respectively. Plasma levels of vitamin C, retinol, ${\beta}$-carotene and ${\alpha}$-tocopherol were 14.7mg/L, 0.7mg/L, 0.2mg/L and 9.1mg/L, respectively which were within normal range. There was no subject with deficiency or marginal level in plasma vitamin A and C. However 1.6% of the subjects had below adequate level in vitamin E. Plasma TAS level was 1.2mmol/L. Correlation data showed that all plasma antioxidant vitamins were positively correlated with plasma TAS. Overall data indicate that the antioxidant status of female college students were pretty good. However it might be necessary to educate them to eat more fruits and vegetables for preventing many chronic diseases in a later life. (J Community Nutrition 5(1) : 13∼20, 2003)
