- This study was performed to investigate the nutrition knowledge, attitudes, and dietary habits of physical education (PE) major and non-majors of male college students. The subjects were 253 students residing in Gyeonggi area. Nutrition knowledge scores of PE major students were lower than that of non-major students. Both PE major and nonmajor students reported TV, radio, and internet as their primary sources of nutrition information. Overall dietary attitude scores of two groups did not differ significantly, but PE major students showed more positive attitudes than non-major students for 'Enjoy eating foods that are good for health'. PE major students took more number of meals a day and took more irregularly than non-major students. Also they used more nutrient supplements than non-major students. PE major students drank more amounts of alcohol and drank more frequently than non-major students. But the smoking status of the two groups was not significantly different. PE major students scored higher than non-major students in dietary habits on balance of meals in spite of their low nutrition knowledge scores. Therefore, it is suggested that nutritional programs for PE major and non-major college students should be developed.

- The study was performed to investigate the relationship of regular exercise to body composition and nutrient intakes of male college students by comparing anthropometric measurements and one-day dietary intakes by 24-hour recall of physical education (PE) majors and non-major male college students. The subjects were 253 students residing in the Gyeonggi area. Only 64.1% and 32.1% of PE majors and non-major students exercised over 4 times a week and PE major students did stronger exercise than the non-major students did. Mean BMI and WHR (Waist Hip Ratio) of the two groups were not different. But percentages of body fat and lean body mass in PE major students were lower and higher, respectively, than those of non-major students. PE major students consumed significantly more energy and other nutrients except iron, niacin, vitamin C, and vitamin E than non-major students. Nutrients consumed less than KRDA was calcium in PE major students and energy, calcium, zinc, vitamin B12, folate, and vitamin C in non-major students. Mean adequacy ratio (MAR) of PE major students (1.00) was significantly higher than that of non-major students (0.94). Index of Nutritional Quality (INQ) of all nutrients except vitamin A of PE major students was also significantly higher than that of non-major students. Nutrients below 1.00 in INQ of both groups were calcium, zinc, vitamin B2, and folate. Our data supports that regular exercise may positively influence on body composition and increase diet quality in male college students. Therefore, an educational program focused on regular exercise along with proper dietary behavior would be needed.

Abstract

- The purpose of this study was to assess several indices of diet quality based on nutrient, food and food group intake of Korean adolescents based on several indices on diet quality according to residence area and body size. Using the data from the 1998 National Health and Nutrition Survey, twenty-four-hour-dietary recalls of a total of 1,110 Korean adolescents aged 13-19 years (male 543, female 567) were analyzed for nutrient adequacy ratio (NAR), index of nutritional quality (INQ), the number of foods (Dietary Variety Score, DVS) and food group consumed (Dietary Diversity Score, DDS). In doing that, it was attempted to apply only the minimum amount of solid foods of Kant's without inclusion of liquid foods because of the very limited variety in Korean foods. Based on weight length index, 13.1% of the subjects were categorized as obese, 14.2%, overweight, 44.4%, normal and 28.3%, underweight. Only vitamin B2 intake was higher in the obese group than in the underweight group. There was no meaningful difference in energy, protein and fat intakes according to the grade of the body size. In terms of residence area, intake of fat, niacin, vitamin B6 and folic acid were lower in the rural areas than in the metropolitan city. Only vitamin E intake was higher in the rural areas. Mean value of NARs (MAR) and INQs (mINQ) was also higher in the metropolitan city than in the rural areas, but there was no significant difference of these two values according to body size of the subjects. Mean DVS was 21.02 for total subjects, and has no difference between male and female and between metropolitan city and other medium-small city. But, the rural areas showed the lowest DVS of 19.05. Mean DDS in which five is a maximum score was 3.3 with no significant difference by sex and by residence area in male subjects. However, in female subjects, DDS in the rural areas was the lowest. According to body size of the subjects, there was no meaningful difference in both scores of DVS and DDS. In conclusion, most indices of nutrient intake and food and food group intake were not significantly different by body size of the subjects, while most indices were significantly different by residence areas: higher in the metropolitan city than in the rural area.

Abstract

- This study was performed to investigate the effect of vitamin C and E supplementation on blood pressure, plasma lipids, folate, and homocysteine levels in smokers and non-smokersof college male students in Gyeonggi Area. The nutrient intakes were determined by a 24hr-recall method. The subjects were divided into six groups: vitamin C supplementation group (n: smokers = 10, nonsmokers = 10), vitamin E supplementation group (n: smokers = 10, nonsmokers = 10), vitamin C and E supplementation group (n: smokers = 10, nonsmokers = 10), respectively. There were no significant differences between the smokers and nonsmokers in terms of anthropometric measurements. Systolic and diastolic blood pressure were significantly higher (p < 0.05) in smokers than that of non-smokers. There was no significant difference in energy and other nutrients intakes between smokers and non-smokers. In plasma lipids levels, smokers had higher plasma triglyceride, LDL-cholesterol, VLDL-cholesterol, total cholesterol concentration than that of non-smokers (p < 0.05). HDL-cholesterol level of smokers had a tendency to be lower than that of nonsmokers. In smokers, AI, TPH, LPH were significantly higher than that of non-smokers (p < 0.01). Plasma folate, homocysteine levels were not significantly different between smokers and non-smokers. The effect of antioxidant vitamins supplementation in smokers: In vitamin C supplementation group, HDL-cholesterol level was significantly increased (p < 0.01) and AI, TPH, LPH were significantly decreased (p < 0.01). In vitamin E supplementation group, HDL-cholesterol level was significantly increased (p < 0.05). In vitamin C and E supplementation group, LPH was significantly decreased (p < 0.05). The effect of antioxidant vitamins supplementation in non-smokers: HDL-cholesterol level was significantly increased (p < 0.05) and AI, TPH, LPH were significantly decreased (p < 0.05) by vitamin C supplementation group. Plasma homocysteine level was decreased by vitamin E supplementation group in non-smokers p < 0.01). The results of this study showed that smoking had a tendency to increase plasma lipids levels that factor into the risk of coronary heart disease. It is considered that antioxidant vitamin supplementation in smokers had a tendency to decrease cardiovascular disease than in nonsmokers.
