The purpose of this study was to compare the dietary habit and nutrient intakes of Korean farmers according to their different family patterns and farming types. Food and nutrient intakes were obtained by food frequency method. The subjects(male 35%, female 65% : mean age, $48{\pm}11 years)$ were compared 46% of nuclear family, 59% of 3-4 person of family size ; 50% of middle-scale farming ; 54% of rice farming. Sixteen percent were over 60 years old group. In aspects of dietary habit, farmers of medium size farming and 10-20 years of farming experience frequently skipped meals. But their appetite was better than small farm famers. Dinner irregularity was more frequent in their group of 3-4 person families. The numbers of food intake were significantly different according to family pattern. Nuclear family groups consumed more kinds of foods. The mean energy intake was 2000Kcal/day, with PFC ratio of 19 : 16 : 65. The energy and nutrient intakes showed the same tendency as the food variety. Intakes of calcium and iron were lower than the Korean RDA. Families with over 5 people consumed higher amounts of protein and minerals. Intakes of thiamin, niacin, and vitamin E were better in large families and large-scale farming groups. As compared with the PMS ratio, the level of monounsaturated fatty acids as higher than saturated FA. The lipid intake was also better in large families and large-scale farming. The results suggest that dietary habit and nutrient intakes were different by family pattern and farming types.

The number of school lunch-supported children who belong to low-income families has been rapidly increased in Korea. This study was aimed at evaluation of nutritional status of school lunch-supported elementary school children. One hundred school lunch-supported children and 119 non-supported children of fourth to sixth year class in 3 elementary schools in Gyeongbuk rural area were selected, and surveys were conducted twice, i.e., once during school term and once during summer vacation in 2006. Food consumption survey during school term was carried out through an interview by dieticians at school-lunch time using a 24-hour recall method, and the survey during summer vacation conducted by recording food intakes for three days by children. Nutrient intakes were calculated using CAN-Pro 3.0 program. School lunch-supported children showed higher rate of skipping breakfast and rather irregular meal time as compared to non-supported students. Eating alone was more frequent in school lunch-supported children than in nonsupported children. The average nutrient intakes and nutrient adequacy ratios were lower in supported children than in non-supported children. During term, percentages of nutrient intakes provided by school-lunch were higher in supported children than in non-supported children. Intakes of energy nutrients were within acceptable macronutrient distribution ranges, but proportion of carbohydrate intake increased during vacation. Analysis of patterns of food intakes based on major food groups (dairy, meat, grain, fruit, vegetable) indicated that meals during term were more balanced as compared to meals during vacation. In conclusion, food behaviors and nutrient intakes of school lunchsupported children were inferior to those of non-supported children during term and during summer vacation. They were provided with more nutrient intakes from school lunch during term as compared to non-supported children. Therefore, it is necessary not only to keep meal support program during vacation but also to provide a proper nutrition education as a part of school lunch program to improve nutritional status and food behaviors of school lunch-supported children.

Purpose: This study is to investigate perceived stress, depression, body mass index (BMI), and nutrient intakes of soldiers in the army. Methods: The subjects were 301 soldiers recruited from two divisions of the army in Kangwon-Do. The data was collected from August 3 to 9, 2009. Perceived stress, depression, lifestyle, dietary habits, BMI, and nutrient intake were assessed. Results: Subjects' distribution for normal weight, underweight, overweight, and obese was 67.4%, 0.7%, 16.3%, and 15.6%, respectively. BMI was related to class, service branch, duration of military service and being on a diet, whereas BMI was not found to be related to perceived stress, and depression. Some nutrient intakes such as dietary fiber, vitamin C, and Calcium was related to depression. Conclusion: This study suggests that soldiers need to undergo stress, depression management, and a nutritional education program.

This study was conducted to investigate the effects of weight control program on nutrient intakes and physical fitness of Korean obese adult women. The subjects of this study were 33 obese adult women aged 30-65 years residing in Seoul. The weight control program for obese women included nutrition education, cognitive behavioral therapy and exercise for 12 weeks. There were significant decrease (p < 0.001) of blood pressure and atherogenic index of obese women after the weight control program. Energy intake was significantly decreased (p < 0.001) from 1556.9kcal to 1044.9kcal after 12 weeks of the weight control program. Also protein, fat and carbohydrate intakes were significantly decreased. The ratio of energy intakes per day for the subjects was carbohydrate 64% : protein 16% : fat 20%. The frequency of vegetables intakes was significantly increased (p < 0.05) and there were no significant differences in other food groups. After the weight control program, muscle endurance, flexibility, balance and explosive muscular strength of subject's physical fitness were significantly improved. These results suggest that the weight control program for obese women may contribute to nutrient intakes reduction and improvement of physical fitness.

This study was to investigate the nutrient intakes from infant formula and supplemental foods of 129 infants(boys 69, girls 60) fed formula, aged from 5 to 12 months. Subjects were divided into $5{\sim}6\;months,\;7{\sim}8\;months,\;9{\sim}10\;months,\;and\;11{\sim}12\;months$ by ages. Dietary assessment was carried out by using 24-hour-recall method. The average intakes and feeding frequency of infant formula were $702m{\ell}$, 4.4 times in boys and $815m{\ell}$, 4.8 times in girls, respectively. Supplemental foods were introduced at the age of $4{\sim}6\;months$ in 86% of the infants. Foods introduced first as the supplemental food were rice gruel soup, commercial weaning foods, fruit juice. Energy intakes were similar to RDA. Daily intakes of calcium at all age groups were higher than the RDA, therefore, calciun overnutrition were elucidated. Average intakes of protein, phosphorus, iron, zinc, vitamin A, vitamin $B_1,\;vitamin\;B_2$, niacin, vitamin $B_6$, vitamin C were above RDA, folate did not meet RDA of infants at all ages. In conclusion, the average status of nutrient intakes of infants was fairly good, however, nutrient intakes from supplemental foods were lower in girls than in boys of $10{\sim}12$months, and folate status seemed to be poor. Therefore, mothers feeding infant formula to their infants should be educated for the importance of supplemental foods and its practice to support good nutrition.

The Dietary Reference Intakes which were developed by the Food and Nutrition Board, National Academy of Sciences of the United States, and Health Canada provide a good deal of information on nutritional requirements which apply to Korea. In addition, the processes of evidence based review of information on nutrient needs, dietary excess, and the assessment and planning of dietary intakes may be useful in Korea as well as North America. However, other aspects of the Dietary Reference Intakes may not be appropriate. This article discusses these issues.

Regular exercise training improves body composition, blood lipid profiles and exercise adaptation. This study was conducted to investigate the effect of exercise training at different times of day on body composition, blood lipids, stress hormones and nutrient intakes. Twenty four male graduate students carried out this experiment. The subjects were divided into three groups; morning exercise group, evening exercise group and control group. Two exercise groups performed running and muscular resistance training at mid intensity for 12 week periods. Body composition, blood lipid profiles, blood cortisol, ACTH and nutrient intakes were analyzed prior to, midway and after training. There were significant differences about interaction between different exercise times and training periods in plasma TG and HDL-C of the evening exercise training (p < 0.05). Also the evening exercise group was showed the decreasing of TC after training (p < 0.05). No significant differences about interaction between different exercise times and training periods were shown in body composition, stress hormones and nutrient intakes in the three groups. But evening exercise training decreased body fat ($\%$) and blood ACTH (p < 0.05). Also the increasing of carbohydrate intakes was shown by the evening exercise training (p < 0.05). In contrast, morning exercise group indicated a decrease of body fat ($\%$) after 6 week training (p < 0.05), but this effect was not maintained after 12 weeks of training. These results suggested that regular evening exercise is more effect than morning exercise from the viewpoint of improving body composition, blood lipids, nutrient intakes and exercise adaptation.

This study was performed to investigate the association between hair mineral levels and nutrient intakes, age, and BMI in female adults who visited a woman's clinic located in Seoul. Dietary intakes were assessed by food frequency questionnaire and mineral levels were measured in collected hairs, and the relationship between these was examined. The average daily nutrient intakes of subjects were compared to those of the KDRIs, and the energy intake status was fair. The average intake of calcium in women of 50 years and over was 91.35% of KDRls and the potassium intake was greatly below the recommended levels in all age groups. In the average hair mineral contents in subjects, calcium and copper exceeded far more than the reference range while selenium was very low with 85.19% of subjects being lower than the reference value. In addition, the concentrations of sodium, potassium, iron, and manganese in the hair were below the reference ranges in over 15% of subjects. The concentrations of sodium, chromium, sulfur, and cadmium in the hair showed positive correlations (P < 0.05) with age, but the hair zinc level showed a negative correlation (P < 0.05) with age. The concentrations of sodium, potassium, chromium, and cadmium in the hair showed positive correlations (P < 0.05) with BMI. Some mineral levels in subjects of this study showed significant correlations with nutrient intakes, but it seems that the hair mineral content is not directly influenced by each mineral intake. As described above, some hair mineral levels in female adults deviated from the normal range, and it is considered that nutritional intervention to control the imbalance of mineral nutrition is required. Also, as some correlations were shown between hair mineral levels and age, BMI, and nutrient intakes, the possibility of utilizing hair mineral analysis for specific purposes in the future is suggested.

This study analyzed the physical indices, food habits and nutrient intakes of patients with hypertension, to provide better research data for the prevention and the cure for disease as well as basic data for nutrition education. The subjects were 44 patients who visited the general hospital, located in Daegu, to receive hypertension treatment The lifestyle, food habit, nutrient intakes, anthropometric measurements, body fat and blood pressure were measured as main indices. By the BMI, $72.8\%$ of the patients were over weight or obesity $(>23\;kg/m^2)$. In the male group, the WHR tended to increase according to the BMI (p<0.05). In the female group, the body fat tended to increase according to the BMI (p<0.05). The group with more monthly income showed lower systolic blood pressure than the group with smaller monthly income (p<0.05). The scores about food habits concerning balanced diet and preference for salt were low, which implied that food habits of subjects were not desirable. The intakes of riboflavin and calcium didn't meet the RDA requirements. Especially, the lack of calcium was more ap~nt in the female patients than the male ones. Despite this, they had more than enough protein, vitamin C, and iron. The physical indices according to blood pressure revealed that the group of higher blood pressure showed greater WHR (p<0.001). The male group with higher systolic blood pressure showed greater BMI than one with lower systolic blood pressure (p<0.05). As for nutrient intakes according to blood pressure, the group with higher blood pressure had more sodium and iron than one with lower blood pressure (p<0.05). The patients with hypertension tended to be more overweight or obese, preferred salty foods, and were in an unbalanced state of nutrient intakes. Thus more systematic and ongoing measures should be pursued to take care of patients with hypertension.

The aim of this investigation was to assess the relationship between food habits and nutrient intake in college female students. Nutrient intakes of 149 female subjects aged 19.3 y were determined by using 24-hr recall. The questionnaire included general characteristics and food habits (frequency of breakfast and fast food intake). Body composition was determined by bioim- pedance analysis. Nutrient analysis was performed with Can pro software. Statistics were generated using SAS 9.3 (SAS Institute, Cary, NC). Mean intake of energy, fiber, calcium, potassium. vitamin $B_2$ and vitamin C by the subjects ware below KDRIs. The nutrients for which the largest proportion of subjects showed inadequate intakes (less than the RI or AI) were potassium, calcium, vitamin C and fiber. Subjects that consumed fast food ${\leq}6$ times showed significantly lower intakes of calcium, potassium, fiber, vitamin A, vitamin $B_6$ and vitamin C. Subjects who skipped breakfast more frequently showed significantly lower intakes of energy, carbohydrate, fiber, calcium, iron, potassium, vitamin $B_2$ and vitamin C than subjects who ate breakfast more frequently. This is strong evidence that higher intakes of nutrients such as potassium, fiber, and calcium are associated with increased frequency of eating breakfast or decreased frequency of eating fast food. Low calcium, fiber, and potassium intakes may thus lead to chronic diseases. Nutrition education can be an important facilitator for improving nutrient intakes.
