Background: Modifying lifestyle factors such as diet and exercise can reduce the risk of cancer. Psychological stress (PS) might be indirectly associated with cancer because it alters lifestyle factors. However, the relationship among these variables has not been fully investigated. Thus, we examined interactions between self-reported PS (SRPS) and habitual exercise on diet. Materials and Methods: In all, 5,587 men and 2,718 women were divided into "exerciser" and :non-exerciser" groips, based on whether they exercised reguarly, and classified into three SRPS levels: low, moderate and high. Diet was estimated using a validated food frequency questionnaire. Using a general linear model, food and nutrient consumption was estimated for each SRPS level in the 2 exercise groups, and the interactions between SRPS levels and exercise were calculated. Results: In women, the intake of pork and beef, low fat milk and yogurt, natto (fermented soybean), carrots and squash, other root vegetables, mushrooms, seaweeds, and wine along with the nutrients vegetable protein, soluble, insoluble and total dietary fiber, daidzein, genistein, carotene, retinol equivalents, vitamin B2, pantothenic acid, potassium, calcium, magnesium, phosphorus and iron demonstrated significant interaction with SRPS and habitual exercise (p for interaction <0.05). In men, raw and green leafy vegetable and fruit and vegetable juice significantly interacted with SRPS and habitual exercise (p for interaction <0.05). Conclusions: We suggest that certain foods and nutrients, which are thought to have a protective effect against cancer, interact with SRPS and habitual exercise, especially in women. This information is valuable for understanding and improving interventions for cancer prevention.

The purpose of this study was to evaluate the dietary habit, nutritional condition and quality of everyday meal for college students. The number of the subjects was 102 and they were divided into three groups by their residing types; students living with their parents (n=34), students living in dormitory (n=34) and students living independently off the campus (n=34) Questionnaire, 24hour dietary recall for food intakes, and body composition analysis were used. SPSS program was used for the statistics. In general health matter, the average age for each group of students was $21.2kg/m^2$, $20.9kg/m^2$, and $21.9kg/m^2$ respectively. And heights, weights, muscle mass, body fats and BMI were not significantly different between groups. Results on dietary habit showed that students living with their parents had better meal pattern and regularity for breakfast than other groups. Also, for dietary evaluation, students living with their parents showed better extent of intake of milk than other groups. Evaluation on nutrients intake showed that amount of calcium, vitamin $B_2$, folic acid intake in student living independently off the campus were lower than those of the other groups(P<0.05). And MAR(Mean Adequacy Ratio) was not significantly different between groups, however INQ(Index of Nutritional Quality) and NAR(Nutrient Adequacy Ratio) of calcium were lower in off the campus group than other two groups. In conclusion, students living independently had worse eating habits and showed lower intake of calcium than those living with their parents or living in a dormitory. Therefore nutritional education for improving well-balanced dietary habits and optimal intake of nutrients are required especially for students living independently off the campus.

The present study was conducted to evaluate nutritional intake by lunch-box of middle school girls who live in Chonbuk area. Anthropometric measurements and food intake from lunch-box over a three day period were investigated in a total of 110 middle school girls from rural (n＝37) and urban (n＝73) areas. The results are summarized as follows : 1. Not all the steamed rice in the lunch-box had enough mixed-cereal. 2. In the survey of food intake by food groups, 70.5% of the food came from the cereal group. 3. The intake of protein, phosphate, Vitamins $B_1 and B_2$, niacine and Vitamin E were adequate, however, the intake of other nutrients was significantly lower than those of one-third of the Korean RDA.4. Protein, lipid, and zinc intakes of the students from the rural area were significantly lower than those of students from the urban area. however, the carbohydrate and dietary fiber intakes of those in the rural area were significantly higher than those of the students in the urban area. 5. The percentage of calories from carbohydrate : protein lipid ratio was 67.6 : 12.2 : 16.9 for students in the rural area and 59.2 : 14.9 : 22.5 respectively for those in the urban area. In Summary, the intake of calcium, iron, Vitamins A, $B_6$, and D, folate and zinc from lunch-box in middle school girls was much lower than that of one-third of the Korean RDA. The intake of carbohydrate and dietary fiber of the students in the rural area was significantly higher, but that of protein, lipids, and zinc was lower than that of the students in the urban area. Therefore, nutritional education programs for both students and their parents should be provided to improve the daily food intake from lunch-box.

As recently many studies on the relationship between excessive sugar intake and chronic disease have been reported across the world, more attention to sugar intake has been paid. Sugars, called simple sugars, is a kind of carbohydrate and sum of monosaccharides and disaccharides. Sugars that are particularly related to health are added sugars or free sugars, which are added to food by processing or cooking. It is generally not to give satiety and increases energy density without other nutrients. Especially, the major food source of added sugar is sugar-sweetened beverages(SSBs), from which sugars are closely linked with health outcome. The total sugar intake in Korea is 61.4 g per day and it is almost half of those in the western countries such as the U.S. or Australia and it is within the recommendation level by the Dietary Reference Intakes for Koreans. However, when it is classified by age groups or food sources, sugar intake in adolescents and young adults are high and the sugar from processed foods is also high that would lead to high intake levels of added sugar. Particularly, the frequency of SSBs, the major food source of added sugar, is the highest among 20's. While the studies of excessive sugar intake with chronic diseases including obesity, type 2 diabetes, metabolic disease, cardiovascular disease reported in the Western populations, those in the Korean populations have just started. Given our dietary practice is very different from those in the western population, more prospective studies would be necessary to evaluate sugar intake by type or food source exactly and examine its relationship with chronic diseases in the Korean population.

The study was carried out to investigate the dietary attitude and hematological status of the middle school football players in Busan. The survey was conducted from September 15 to October 15, 2006 by questionnaires and data analyzed by the SPSS program. The results are summarized as follows: The weights and body mass indices of the football players were significantly lower than those of the control. Dietary attitude scores showed no significant differences between the groups. Nutrition knowledge scores of the football players were lower than those of the control. Both football players and the control preferred the sweet taste rather than others. The football players preferred the hot taste, meats, and fish rather than the control did. Serum triglyceride level of the football players was significantly lower than that of the control. Blood iron level was significantly lower in the football players than in the control. Blood urea nitrogen concentration was higher in the football players than in the control. Therefore proper nutritional education programs are required for middle school football players to improve their nutritional status and physical strength.

The purpose of this study was to investigate food habits, nutrients intakes and nutritional quality of the preschool children living in Seoul. The study was performed by analyzing a questionnaire answered by the mothers of 233 subjects aged 2 to 6 years old. A three-day dietary intakes survey, using a 24 hour recall method was used by both the mothers and teachers of the children in day care centers. Twenty eight, 65.9 and $21.8\%$ of preschool children were underweight, normal and overweight or obese, respectively. It was found that $19.8\%$ of preschool children replied that they skipped breakfast sometimes. The major reasons for skipping breakfast were 'snacks' ($38.3\%$) and 'no appetite' ($32.6\%$). The proportion of subjects having unbalanced meals was $61.6\%$. From the 24-recall survey, it was found that all nutrients intakes were higher than those of the Korean RDA except zinc. The proportions of carbohydrate, protein and fat from total calories were 56,1, 17.2 and $30.7\%$. The P/M/S ratio was 0.62 : 0.86 : 1. Nutrient adquacy (NAR), mean of nu-trient adequacy ratio (MAR) and index of nutritional quality (INQ) were considered adequate. In conclusion, the dietary intakes of children aged 2 to 6 were assumed adequate judging from nutrient intakes, although some attention should be paid to fat intake in this age group.

The purpose of this study is to offer information related to recommended dietary allowances for young children and food guidelines for preschool children in Sweden. Sweden, located in Europe, is the most developed country for young child care system. Swedish nutrition policy background, Swedish recommended dietary allowances for young children, and food guidelines of early childhood education center in Sweden were used. The number of Swedish child care centers increased from 70,000 in 1970 to 700,000 in 2000. The Swedish Institute of Public Health promoted children's indoor and outdoor activity. The aim of the Swedish public health contains children's safety, good food habits, and eating food safely. Swedish Food Administration made recommended dietary allowance and food guidelines for children care centers. The aim of food guidelines was to increase energy, calcium, iron, and dietary fiber intake. Swedish RDA contains minimum and maximum intake as well as mean intake for macro and micro nutrients. The fat intake ratio of energy is increased for younger children. For preschool children, the food guideline is determined by dietary allowances for breakfast, lunch, and snack respectively. Food guideline contains meal time schedule, menu for each meal using food model, amount of food for age group, and recommended dietary allowance for each meal. It is recommended for Korean early childhood education center: 1) Korean RDA for young children should be made range of intake, minimum and maximum intake. 2) Food guideline should be make for Korean child care center. 3) Korean child care centers should offer an afternoon snack twice for children who return home late. 4) Nutrition education program for preschool teachers should be developed for children's good eating habits and health promotion.

In an attempt to investigate mothers' perceptions of factors affecting preschool children's food preferences, their policy improving food intake and belief in food selection, in-depth interviews with 30 mothers who had preschool children were conducted in Daegu and Busan. The interviews were tape-recorded and the contents of interviews were analysed by researchers. Most mothers and children liked meats. It was found that children usually disliked vegetables such as onions, carrots, and green onions. Mothers perceived that many factors affected their children's food preferences: mothers' and fathers' food preferences, food offering at meals. mothers' food intake during pregnancy, children's food intake during weaning period, heredity peer pressure, and advertisements on television. Mothers made efforts to improve childrens food intakes in many ways: change of cooking method, emphasizing function of nutrients and food for health, conciliation and enforcement, and comparison to other children. The most affecting belief for mothers in food selection was family members' food preference. Health, balance in nutrient intake degree of food processes food additives, chemicals, convenience, diversity, and economy were also important beliefs to select food. Convenience was especially the primary belief in choosing and preparing children's snacks. Mothers offered frozen dumplings and meat, instant noodles, tuna, and ham for snacks for convenience. These results showed that mothers understood many aspects affecting children's food preference tried to improve children s food intakes and had several beliefs in food selection. We concluded that it is necessary to give information for mothers to make healthy snacks in a short time and chance to learn cooking skills.

The purpose of this study was to investigate the effects of regular maternal exercise on maternal nutrients intake and pregnancy outcome. The number of subjects were 567 pregnant women at local general hospital in Daegu. General characteristics data and 24- hour food recalls were collected by trained interviewer. Structured interview and medical record review were carried out at first prenatal and delivery visit(included age, delivery history, height, pre-pregnancy weight, and pregnancy outcome etc). Regular exercise performance was surveyed at third trimester and 31.4% of subjects exercised regularly Overall weight gains during pregnancy were 13.9 $\pm$ 3.8kg and 14.7 $\pm$ 4.7kg in the exercise and sedentary group, respectively. The type of exercise was mainly strolling and light aerobic exercise. Usually firstpara subjects exercised more regularly than multipara subjects. There is no significant difference between regular exercise and severity of morning sickness. Weight gain during pregnancy was not relate to regular exercise. Though there is not statistically significant, the nutrients intakes were higher in regular exercise group than in sedentary group. We concluded regular exercise during pregnancy neither influenced pregnancy weight gain, severity of morning sickness nor baby birth weight but it could affect the nutritional and health statues of mother.

To assess the food intake and diet quality of Koreans living in rural areas with discriminative environment, this dietary survey was conducted with 553 subjects living in five different rural areas using a one-day, 24-hour recall method. The average weight of total food intake was 1066g, with vegetable and animal food comprising 83.75 and 16.3% of total food intake, respectively. The average daily food intakes of residents in the five areas were 985g, 1005g, 1028g, 1318g, and 964g, and were significantly different(p<0.001). Residents of Ulju consumed the largest amount of food, 1318g. The total number of food items consumed was 336. The foods consumed in largest amounts were rice(223g), Korean cabbage-Kimch'i(111g), and soybean curd(41g). The foods consumed most frequently were rice, Korean cabbage-Kimchi, green onion and garlic. When investigating the consumption pattern of the major five food groups, only 5% of subjects consumed all five groups. The groups most frequently missing were dairy products and fruits. The average number of foods consumed per day was 16.8, but differed significantly by area(p<0.001). The number of major food groups (DDS, dietary diversity score) and that of food items(DVS, dietary variety score) correlated positively with NAR (nutrient adequacy ratio) and MAR (mean adequacy ratio). People with a DDS of above 4 or DVS of above 20 met two-thirds of the recommended dietary allowance for most nutrients. When assessing the dietary quality of subjects using DDS and DVS, many people appeared not to have a desirable food intake. dietary guidelines should be made considering the nutritional characteristics of different areas to improve the health of people living in those areas.
