This study examined the influence of the nutrient intake status, dietary habit, and academic stress of elementary school children on their academic achievement. Two-hundred and twenty-four fifth-graders in Bucheon-si, Gyeonggido were surveyed. The study included the 24 hr-recall, anthropometric measurement, assessment of stress level and academic achievement. The subjects were normal in height, weight and Rohrer index, but higher percentage of underweight was seen in girls and vice versa in boys. The overall nutrient intake and dietary habits were fairly good, but Ca and folate intake was less than 75% KDRIs and dietary habits of boys were inferior. Academic stress level of all the subjects was not high. In terms of academic performance and its relations with nutrient intake, the more the amount of nutrient intake, the higher the academic performance. Especially, it was true for the energy, protein, phosphorus, potassium, zinc, polyunsaturated fatty acids, and n-6 fatty acid intakes (p < 0.05). The overall academic performance was higher for those who eating-out less frequently. Children with higher comprehensive dietary habit scores have shown better academic performance (p < 0.05). Less stress implied to those shown higher academic achievement while those with relatively poor academic performance showed high stress level since their grade did not improve as much as they anticipated. In conclusion, the academic achievement was higher for those who have a better nutritional status, better dietary habits, and lower stress levels. Therefore, it is critical for nutritionists, parents, and teachers to improve the nutritional status and dietary habits as well as to help them manage their stress levels, which will eventually contribute to an enhanced academic performance.

This study examined the factors related to stages of dietary behavioral changes among 1449 child bearing aged women (mean age $\pm$ SD = 25.6 $\pm$ 5.3 years) residing in large cities. A self administered questionnaire was used to assess stages of dietary behavioral change, meal balance and regularity, food availability, nutrition knowledge, body mass index, nutrient intake, and psycho-social factors including self efficacy, perceived benefits and barriers, social modeling. Undesirable dietary behaviors (precontemplation and contemplation) were shown among 45.1-57.4% of the participants, among those, 33.4-43.0% were precontemplators. Participants' self efficacy scores associated with dietary changes were higher in specific situations (3.42) as compared to general situations (2.86). Similarly, they appeared to perceive more benefits (3.86) rather than barriers (2.76) by changing their inappropriate eating habits. Perception and accuracy scores of nutrition knowledge were relatively high, indicating 90.9 and 80.1, respectively. In terms of food availability at home, fresh fruits received the highest score, followed by milk and milk products, vegetables, meat, alcoholic beverages and soft drinks. In social modeling assessment, family members, as compared to friends, appeared to have better dietary habits. Stages of dietary behavioral change assessed in terms of meal regularity were associated with nutrient intake, showing higher energy and carbohydrate intakes but lower fat intake among those who belonged to the action and maintenance stage. They also presented higher self efficacy and perceived more benefits and less barriers regarding the change of undesirable eating habits. Fresh meat and vegetables were more available among those maintaining desirable dietary habits. Results of this study presented the significant relations of motivational and reinforcing social factors with stages of dietary behavioral changes and a need for the development of tailored nutrition education program considering these factors for child-bearing aged Korean women.

The purpose of this study was to evaluate the effectiveness of an intervention program using dietary consult and physical exercise conducted by public health center in Chuncheon city for obese adults. This study used a pretest-posttest design. The subjects were 58 out of 90 obese adults with body mass index (BMI) greater than $25kg/m^2$ who completed all education sessions for 8 weeks. Data on dietary habits, dietary behaviors, nutritional knowledge, anthropometric parameters and biochemical indices and daily nutrient intakes assessed by a 24-hour recall were collected before and after the intervention program., in order to evaluate program effectiveness. After the intervention, there were positive changes in exercise status and dietary habits and nutrition knowledge accuracy. Especially, the answer of 'I drink a cup of milk every day' were significantly improved (p<0.001), and the answer of 'I don't overeat', which is a dietary attitude question was significantly improved (p<0.05). Dietary intakes of most of nutrients were not significantly different between pre-test and post-test. But calcium (p<0.05), potassium (p<0.05), vitamin A (p<0.01), vitamin E (p<0.05), and folic acid (p<0.05) were significantly increased in the female group after the intervention. Weight (p<0.05), BMI (p<0.01), blood pressure (p<0.001), were significantly decreased after program, but changes of skeletal muscle mass, body fat mass were not significant. Resting heart rate (p<0.01), flexibility (p<0.001), whole body reaction (p<0.05), grip strength (p<0.01) and balance (p<0.01) showed positive changes after the intervention. Blood glucose level in serum was significantly decreased (p<0.001). These results indicated that dietary education and exercise program was effective not only for weight reduction but also for the improvement of physical fitness in obese adults.

This study conducted to assess the effectiveness of nutrition education program for elderly females with various diseases. Forty subjects(hypertension ; 20, diabetes ; 12, hyperlipidemia ; 8) out of 56 completed the 7 weeks nutrition education program. The nutrition education program was based for healthy food habits and dietary guidelines for each specific disease. It also included practicing individualized menu planning and exercising program. Energy, calcium, iron, vitamin A and ash intakes significantly increased in the hypertension group. total sodium intake did not decrease, however sodium intake per kcal decreased significantly(p〈0.05). Elderly with diabetes did not show any changes in dietary intakes. Dietary protein, plant fat, ash, and sodium intakes were significantly elevated(p〈0.05), but cholesterol intakes significantly decreased(p〈0.05) in the hyperlipidemic group. Elderly with hypertension agreed strongly with changes of food habits such as increasing milk intake, and decreasing Kimchi, soup, pickles and salty food, and table salt intakes after nutrition education. Diabetic elderly showed significantly improved food habit scores in decreasing white rice intake, sugar intake and increasing sea-weed consumption, vegetable consumption and exercise. Hyperlipidemic elderly did not show much improvement in food habit scores except in biochemical indices. However, mean serum glucose and atherogenic index decreased in the diabetic and hyperlipidemic groups after education, respectively.

This study was to investigate the food habits and the dietary behaviors of university students. Questionnaires were completed by 492 students in five different departments. The data were analyzed by SAS program. The results are summarized as follows: Fifty(10.2%) of respondents were vegetarians, 81(16.4%) were heavy meat eaters and all the others were light meat eaters. All students had their biggest meal at supper. Three hundred and ninety-three(79.9%) of the respondents usually had rice for breakfast. Three hundred -sixteen(64.2%) ate 3 meals a day, 155(31.5%) ate 2 meals and all the others ate 1 meal or more than 3 meals. The length of mealtime was 30 minutes in 268(54.5%), 10 minutes in 209(42.5%) and more than 1 hour in all the others. Respondents considered taste the most important meal factor with nutrition, hygiene, and amount ranked accordingly. A majority(63.0%) of respondents ate occasionally ate between meals, while 28.1% snacked frequently, and 8.9% ate no snacks. Although nutrition dept. students had studied nutrition subject, some results of nutrition dept. students were desirable and others were undesirable in dietary behaviors. Therefore they should have a nutritional education program to improve their food habits and the dietary behaviors for students' health. And nutritional education program should be organized practically and systematically.

The purpose of this study was to collect basic data on the prevention of and education about diabetes mellitus for the nutritional management of a diabetes mellitus risk group. The study which took place in Kangbukgu, Seoul, involved a diabetes mellitus risk group (DMR $\geq$ 110 mg/dL, 61), of males and females, aged 36 to 68 years, and a group of healthy people as a control group ( < 110 mg/dL, 183), using luting blood sugar (FBS) levels. The proportion of people in the abnormal range was higher in the DMR than that of control group for total cholesterol, high-density lipoproteins-cholesterol (HDL-C), total protein, glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT) and creatinine. Particularly with respect to serum protein the proportion in the DMR in abnormal range (p < 0.05) was significantly higher than that of the control group. The proportion in the DMR with a family history of disease was significantly higher than that of the control group (p < 0.01). Using body mass index (BMI), waist-hip ratio (WHR) and relative body weight (RBW), the obesity indices in the DMR was higher than that of the control group. Comparing the DMR and the control group with respect to dietary habits, it seems that the DMR had more undesirable dietary habits than the control group. When the intake of each nutrient for the DMR and the control group was compared to the Korean recommended dietary allowances (RDA), the proportion of excess intake and deficient intake in the DMR was higher than that of the control group. The DMR showed a greater undesirable dietary intake pattern as compared to that of the control group, based on the RDA. With respect to the dietary diversity score (DDS) and the mean adequacy ratio (MAR) for quality estimation of the overall flood intake, the DMR showed a feater undesirable pattern than the control group. According to the above results, the DMR tended to have more undesirable eating habits when compared to the control group. Therefore, to provide a more efficient nutritional education program for the DMR we must conduct lurker studies on eating habits, so as to provide systematic nutritional management based on theme differences between the DMR and the control group.

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 examines the dietary, exercise, and other daily habits of Daegu residents and how these relate to the residents' perception of their own health status, and comparatively analyzes the lifestyles and daily habits of those who perceive themselves to be healthy and those who do not. This research study used Inbody 230(Body composition analysis, Biospace, Korea) to make body and health measurements such as body composition and obesity index. Also, included in this study was a survey on the lifestyle patterns of the residents. The data from this survey was analyzed with SPSS. The results show that among the residents of Daegu, those who perceive themselves to be healthy have lower body fat and are less obese on average. With respect to dietary habits, those who believe themselves to be healthy have more regular dietary habits such as rarely skipping a meal than those who do not believe themselves to be healthy. In addition those who say they are healthy exercise more frequently and for a longer duration than those who say they are not healthy. As for daily habits, those who report they are healthy show greater satisfaction with life and suffer less from stress than those who report themselves to be unhealthy. This study demonstrates that in order to improve people's health in Korea, good dietary, exercise and daily habits need to be emphasized. Additionally, health education and health awareness programs need to be established in each region. Follow-up studies should be conducted afterwards.

The objective of this study was to investigate parents' behavior and attitudes regarding their kids' snacking and dietary life education. A survey was conducted with the parents (N=412) of elementary students from seven provinces, includeing Seoul, Busan, Daegu, Kwangju, Gyungnam, Chungnam, and Kangwon. Kids' snacks consisted mainly of purchased foods rather than homemade foods. Parents' main concerns regarding kids' snacks were nutrition (44.9%), taste (24.3%), and safety (23.5%). Over 50% of parents checked food labels, especially expiration date (96.4%), food ingredients (49.5%), and food additives (33.5%). The snack items frequently provided to kids were fruits (62.8%), milk (55.5%), bread (47.1%), and snack items (23.3%). Parents responded that the amount of their kids' snacking was adequate (47.8%), small (33.7%), or large (18.2%). The results show that more research is needed regarding the adequacy of kids' snacking, considering that 15.7% and 22.4% of the children ate more and less, respectively, than their daily energy requirement. 76.5% of the parents performed home education regarding their kids' dietary habits, especially on the topics of 'balanced diet' (83.9%), 'healthful food' (53.7%), and 'eating three meals a day' (40.2%). Parents obtained dietary information from TV (65.2%), internet (12.0%), and newspapers (7.0%). From this study, we found that parents perceived their kids' snacking behavior correctly, and considered home-education for their kids' dietary habits positively. However, the information resources were limited, which makes it necessary to develop parents' education programs.

Purpose: This study was done to develop a pregnancy nutrition knowledge scale and to examine the relationships between pregnancy nutrition knowledge and eating habits in pregnant women. Methods: With convenient sampling, 189 pregnant women who used community health centers for their ante-natal care were recruited. Data were collected using a self administered questionnaire including items on pregnancy nutrition knowledge (18 items) developed by researcher and items on eating habits (14 items). Cronbach's alpha and exploratory factor analysis were examined to test reliability and construct validity of the scale. Pearson's correlation coefficients were used to identify the relationship between pregnancy nutrition knowledge and eating habits. Results: Cronbach's alpha of 18 items was .80. In factor analysis using principal components, 6 factors explained 65% of the total variance. The level of pregnancy nutrition knowledge was not sufficient but correlations between pregnancy nutrition knowledge and some of eating habits were significant. Specifically, pregnancy nutrition knowledge was positively correlated with good eating habits and negatively with bad eating habits. Conclusion: The pregnancy nutrition knowledge scale developed in this study is acceptable for nutrition education led by nurses. Pregnancy nutrition knowledge and eating habits are considered as major variables for ante-natal nutrition education. In future studies, explorations are needed on dietary intake and physiological indices in pregnant women, comparison of women at risk with those not at risk, and development of nutritional education programs for pregnant women.
