The main purpose of this study is to analyze and evaluate the types of environmental awareness as an eco-friendly/non-eco consumer among Korean University students. The data of research were collected by a survey questionnaire with face-to-face interviews in South Korea. The questionnaire was consisted of fifty-six variables with five questions of demographic factors. The variables employed in the survey were drawn from the literature review and suggested by the focus group to make the questionnaire influential in studying the trends of eco-friendly consumers. Descriptive statistics and binary logistic regression modeling were used by two groups of the student consumers to find the significance of each factors; practice, habit, recognition, concern, and insistence. Environment-friendly consumers show significant difference with non eco-friendly consumers including practice, habit, and concern toward environmental issues.
The amount of salt intake of Korean people is 11.4 grams per a day, which is 2.3 times of the recommended daily salt intake by WHO - 5 grams of salt a day. The relationship between high salt consumption and increased risk of high blood pressure, observed not only in hypertensive but also in normotensive patients. High salt intake is also associated with an increased risk of heart attack, cerebral ischemia and osteoporosis. Therefore, this research is for developing a salt taste sensor to reduce sodium consumption and improve meal habits for the perception of a more bland taste of most foods. When the sensor was put into food sample, current intensity achieved with distribution cables. Current intensity was correlate with a simple equivalent of salt taste stimulus intensity. The salt taste sensor consists of salinity & temperature measuring probe, signal processing circuit and LCD display & LED warning light. When salinity is going over a set point, LCD displayer indicate salt taste on LCD panel by percent value (%), and at the same time, blue LED light change to red LED light. So we could know the grade of salt taste in soup before meals conveniently and objectively. The results show that operating range of 10 to $80^{\circ}C$ and accuracy of ${\pm}0.1%$ were achieved with an analysis time of about 2 or 3 sec. Moderate reductions in salt intake can help to avert adult diseases and lead a healthy life.
Objectives: This study was performed to examine the clustering of lifestyle risk factors for chronic diseases in urban poor and rural adults. Methods: As a cross-sectional study, a questionnaire survey was conducted in 2003. Data was collected from 468 urban poor adults and 385 rural adults. And 848 persons data was used for final analysis. We surveyed their smoking habit alcohol consumption, exercise habit education and disease histories. Result: In mea about 25% of the urban poor subjects and about 20% of the rural subjects had three lifestyle risk factors(Prevalence ratio was 1.29). And, in women, about 1.5% of the urban poor subjects and about 0.5% of the rural subjects had three lifestyle risk factors(Prevalence ratio was 4.00). Especially in men, clustering of smoking and excessive alcohol consumption was strongest both the urban poor and rural subjects(Observed/Expected ratio(O/E): 1.4 in the urban poor subjects, 1.3 in the rural subjects). Conclusions: These findings show that the lifestyle risk factors cluster among the urban poor and rural adults. And the clustering is stronger in the urban poor adults than the rural adults. This tendency was important for health education and health promotion. We suggest that more intensive health promotion strategies for the urban poor adults are needed.
This study was conducted to identify dietary factors that may affect the occurrence of gastric cancer in Koreans. Preoperative daily nutrition intake and diet quality of patients diagnosed with gastric cancer were evaluated. Collected data were comparatively analyzed by gender. The results were then used to prepare basic materials to aid in the creation of a desirable postoperative nutrition management program. The subjects of this study were 812 patients (562 men and 250 women) who were diagnosed with gastric cancer and admitted for surgery at Soonchunhyang University Hospital between January 2003 and December 2010. Nutrition intake and diet quality were evaluated by the 24-hr recall method, the nutrient adequacy ratio, mean adequacy ratio (MAR), nutrient density (ND), index of nutritional quality (INQ), dietary variety score (DVS), and dietary diversity score (DDS). The rate of skipping meals and eating fast, alcohol consumption, and smoking were significantly higher in males than those in females. The levels of energy, protein, fat, carbohydrate, phosphorous, sodium, potassium, vitamin $B_1$, vitamin $B_2$, niacin, and cholesterol consumption were significantly higher in males than those in females. Intake of fiber, zinc, vitamin A, retinol, carotene, folic acid were significantly higher in females than those in males. MAR in males was significantly higher (0.83) than that in females (0.79). INQ values were higher in females for zinc, vitamin A, vitamin $B_2$, vitamin $B_6$, and folic acid than those in males. The average DVS was 17.63 for females and 13.19 for males. The average DDS was 3.68 and the male's average score was 3.44, whereas the female's average score was 3.92. In conclusion, males had more dietary habit problems and poor nutritional balance than those of females. Our findings suggest that proper nutritional management and adequate dietary education for the primary prevention of gastric cancer should be emphasized in men.
Objectives : This study was conducted to evaluate the risk factors associated with cardiovascular disease. Methods : By the questionnaire, the informations of education level, monthly income, alcohol consumption and smoking habit were obtained. Height, weight and blood Pressure(BP) were measured by a trained nurse. The level of lasting blood sugar(FBS), total cholesterol, hight-density lipoprotein(HDL) cholesterol and triglyceride were tested by enzyne method about a group of 2888 males and 1696 females ages ever 20 who had never taken the medication for hypertension. Statistical analysis, ANOVA, stepwise multiple regression, correlation analysis were peformed using SAS package program. Results : There were significant differences among age groups in systolic and diastolic blood pressure, body mass index(BMI), FBS, triglyceride and cholesterol except HDL-cholesterol. The risk factors associated with systolic and diastolic BP significantly in male were BMI, age, alcohol intake, but in female BMI, age. Smoking habit had a significant negative correlation with BP in both sex. In the group of mild hypertension ($\geq140\;mmHg\;or\geq90\;mmHg$ defined by JNC-VI) and hypertension ($\geq160\;mmHg\;or\;\geq95\;mmHg$ defined by WHO), the percent of diabetes $(FBS\geq140\;mg/dl)$, hypercholesterolemia $(\geq240mg/dl)$, and hypertriglyceridemia $(\geq200\;mg/dl)$ were significantly higher compared with normal group in male and female. BMI, and alcohol consumption had a positive correlation with FBS, total cholesterol and triglyceride. Smoking had a positive correlation with cholesterol and triglyceride but negative correlation with HDL-cholesterol in male. The educational attainment had a negative correlation with BMI, FBS, total cholesterol and triglyceride in female. Conclusions : This study suggested that drinking, smoking, and BMI and lower educational level were associated with hypertension, hyperlipidemia and diabetes, but further evaluation was needed by prospective intervention study.
Objectives: A higher consumption of vegetables is emphasized as the core component of most dietary guidelines. Thus, this research investigated the dietary habits and influencing factors of vegetable preferences of adolescents. Methods: This study was conducted by using a self-administered questionnaire. 400 students from two high schools in Gyeongnam (193 boys, 207 girls) participated in the survey. The questionnaire consisted of the following variables: dietary habit, dietary action guide and factors based on Social Cognitive Theory (SCT). Results: The dietary habits of subjects showed significant differences depending on whether they prefer vegetables or not. The subjects in the group who liked vegetables had better dietary habits than the other group. Also, the study determined that the most important reason for liking or disliking vegetables is due to the taste. In the practice of dietary guidelines, the group of subjects who liked vegetables followed dietary guidelines more closely than the other group (p < 0.001). When the factors based on SCT were analyzed, personal factors showed significant differences between the groups: outcome expectation (p < 0.001), self-efficacy (p < 0.001) and affective attitude (p < 0.001). Personal factors and rated vegetable preferences showed a significant correlation in multiple regression analysis (F=42.015, p < 0.001). Conclusions: These results showed that vegetable preference is associated with a key point of desirable dietary habits among subjects. In order to increase vegetable preference or consumption, it is important to focus on strengthening not only self-efficacy of students, but also affective attitude of vegetable.
The purpose of this study is to investigate the change in ecological footprint made by the eco-friendly consumer education program, and ultimately, to help the high school students, future consumers, have eco-friendly attitude. This study will be contributed to helping them to understand the importance of the eco-friendly consumption and the seriousness of the environmental problems arising from their bad consumption habit, to get interested in the environmental problems in daily lives, and to reduce the ecological footprint through the eco-friendly habit acquired when young. This study is designed to have 60 high school students experience the eco-friendly consumer education program for 10 months and compare the levels of each ecological footprint though two different Questionnaires in five sections: housing, food, transportation, purchase, and waste. The program used in this research consists of three parts: eco-friendly attitude education for consumers, eco-friendly citizen education for consumers, and eco-friendly resource management education for consumers. The data are analyzed by SPSS Window 10.0 program. The findings are as follows: First. The eco-friendly consumer education is more likely to help the students develop critical thought and eco-friendly attitude, unlike the economy-related consumer education. Second. The level of ecological footprint is significantly decreased in the group with the eco-friendly consumer education program. compared to the group without it. Third. Experiencing the eco-friendly consumer education program helps the students have the positive attitude on ecology and lead an environmentally sustainable consumer life. The results show that eco-friendly consumer education can make a contribution to raising the good citizens who have eco-friendly attitude and behavior, lead sustainable consumer life, and try to reduce the level of ecological footprint.
This study was performed to examine the dietary and BMI change of Koreans after moving to America and to identify the factors influencing changes of BMI. The subjects were 192 Korean-Americans (men : 86, women : 106) residing in the eastern area of the U.S.A. 1) subjects reported significantly increased consumption frequency in American foods like, low fat milk(p<0.001), cold cereals (p<0.001), whole wheat bread(p<0.001), hamburger(only in males p<0.01) and pizza(only in males p<0.01). Whereas significantly decreased consumption frequency in fish (p<0.05), cooked vegetables(p<0.001), kimchi(p< 0.001) and cooked rice (p<0.001) were reported. 2) It was reported that weight, accordingly BMI were significantly increased (p<0.01). The smoking habit score was significantly decreased for males (p<0.05). 3) Multiple linear regression analysis for BMI change showed that education years in Korea was the most prominent negative factor(p<0.001) in predicting BMI change in America. Elevated frequencies of alcohol, chicken and soft drink in America were also associated with greater increase of BMI. When the length of residence (increase of age) was included in regression model, the increase of age was the most significant factor (p<0.001). Changes of chicken and soda scores were other significant factors.
This study was conducted to investigate the relationship between alcohol consumption, physical activity and breast cancer risk in Korean women. Newly histologically identified cases (N = 108) were selected at Hanyang and Soonchunhyang University Hospitals in Seoul, from January 1998 to August 1999. Hospital-based controls (n = 121) were the patients who visited at the same hospital in the department of plastic surgery, general surgery and opthalmology. Subjects were asked informations on demographic, reproductive, and history of breast feeding as well as physical activity, exercise habit, alcohol consumption by individual interview. Odds ratio (OR) and 95% Confidence Intervals (CI) were calculated by using unconditional logistic regression after adjusted for confounding factors. Among postmenopausal women, the risk of breast cancer increased with increasing alcohol drinking: relative risk for the highest group ( $\geq$ 150 g per week) compared with the lowest group (never drinking) was 2.05 (CI=1.74-3.79). Association of exercise and high physical activity for breast cancer appeared to be limited to women with high physical index among postmenopausal women. We observed decreasing risk of breast cancer with increasing physical activity index among postmenopausal women (OR=0.49,95% CI=0.56-0.92). Results of this study support a protective effects of physical activity during adulthood for breast cancer. (Korean J Nutrition 36(1): 40-48, 2003)
The chicken has been growing in Korea for more than a thousand years according to the history book and commercially rising for broiler meat only since 1960's. As income increased mainly due to improved economy, it changes the habit of eating especially chicken meat. The structure changes into a coordinated production and marketing system which forced the prevailed small and independent producers to become a contract farmer under the vertically controlled practices. This coordinated structure began in 1970's and evolved continually to occupy around 90 percent of the market in 2010 with some ten (10) private brands being advertising. The industrial organizations have also conducted the generic promotion by a farmer's check-off program. Over the past 20 years, chicken import steadily increased to meet about 25 percent of the domestic market while the export showed negligible growth. As a whole, the structure change and international trade devoted to increased chicken consumption from 2 kg with the independent operation to 11 kg currently under the coordinated system and import. It is predicted that chicken consumption will grow in years to come and the import will also increase in addition to local productions, considering the free trade agreement that has already been in practice with EU and US to open the market eventually from all sources of supply worldwide.
