Objectives: This study compared the differences of postmenopausal women's bone mineral density in relation to the degree of obesity, metabolism index and dietary factors that affect bone mineral density. Methods: The subjects included in the study are 39 postmenopausal women of normal weight with body mass index less than $25kg/m^2$ and 32 postmenopausal who are obese. Anthropometry and biochemical analysis were performed and nutrient intakes and DQI-I were assessed. Results: Normal weight women were $56.03{\pm}3.76years$ old and obese women were $58.09{\pm}5.13years$ old and there was no significant difference in age between the two groups. The T-score of bone mineral density was $0.03{\pm}1.06$ in normal weight women and $-0.60{\pm}1.47$ in obese women and this was significantly different between the two groups (p<0.05). Blood Leptin concentration was significantly lower in normal weight women ($6.09{\pm}3.37ng/mL$) compared to obese women in ($9.01{\pm}4.99ng/mL$) (p<0.05). The total score of diet quality index-international was $70.41{\pm}9.34$ in normal weight women and $64.93{\pm}7.82$ in obese women (p<0.05). T-score of bone mineral density showed negative correlations with percentage of body fat (r = -0.233, p=0.05), BMI (r = -0.197, p=0.017), triglyceride (r = -0.281, p=0.020) and leptin (r = -0.308, p=0.011). The results of multiple regression analysis performed as the method of entry showed that with 22.0% of explanation power, percentage of body fat (${\beta}=-0.048$, p<0.05), triglyceride (${\beta}=-0.005$, p<0.05) and HDL-cholesterol (${\beta}=0.034$, p<0.01), moderation of DQI-I (${\beta}=-0.231$, p<0.05) affected T-score significantly. Conclusions: The results of the study showed that obese women have less bone density than those with normal weight women. In addition, the factor analysis result that affect bone mineral density showed that intake of fat is a very important factor. Therefore, postmenopausal women need to maintain normal weight and manage blood lipid levels within normal range. They also need to take various sources of protein and reduce consumption of empty calorie foods that have high calories, fat, cholesterol and sodium.

The prevalence rate of metabolic syndrome has increased rapidly among the middle-aged and seems to be affected by socioeconomic factors, lifestyles and dietary habits. This research tries to find out the difference in dietary intake between middle-aged with and without metabolic syndrome. Using Korean National Health and Nutrition Survey (KNHANES) in 2005 and 2007, this study investigated 2,382 people (normal: 1,575, disease: 807) in 2005 and 1152 people (normal: 747, disease: 405) in 2007 (between the age of 40 and 64). Analysis was performed to discover the difference in nutrient intakes between people with and without metabolic syndrome. Also differences among people with various socioeconomic factors (such as age, education level, and income level), which can affect nutrient intake, were analyzed. In the nutrient intake people with metabolic syndrome has lower intake in most of nutrients than those of normal group, except carbohydrate. In 2007, normal group had higher intake in most nutrients, except for carbohydrate, sodium, potassium and vitamin A. Carbohydrate: protein: fat (C: P: F) ratio for metabolic syndrome group showed higher rate for carbohydrate, than normal group, in 2005, and 2007. Overall, the higher age and income level, the more carbohydrate intake rate is increase in metabolic syndrome group. The Quality of each nutrient intake was assessed using NAR (Nutrient adequacy ratio) and MAR (Mean adequacy ratio). According to the MAR, there was significant difference in 2005, 0.83 for normal group and 0.81 for metabolic syndrome group but there wasn't any in 2007 (0.81 for normal group, 0.82 for metabolic syndrome group). By NAR, in 2005, all nutrient except phosphorus, iron, vitamin A for Normal group higher then those of metabolic syndrome group (p < 0.05). In 2007 intake of metabolic syndrome group were higher then those normal group in most of nutrient by NAR. For age, education and income, MAR for normal group is higher then that of metabolic syndrome. In conclusion, Quality of nutrient intake in normal group is better then in metabolic syndrome group. Therefore, it is necessary to monitor dietary of intake people with metabolic syndrome, and necessary measures should be taken.

This study was performed to investigate the consumption of coffee beverages and energy contribution ratios of coffee beverages and accompanying snacks by college students in Deajeon City and Chungnam Province in Korea. Questionnaire survey, dietary survey, and snack survey using food record method during 3-days were carried out. As a result, we found that 86.9% of male students and 75.6% of female students consumed coffee beverages usually, with no differences between the two groups. However, the frequency of coffee beverages consumed by female students out-numbered that of male students by 1 cup a day to 1-2 cups a week (p<0.05). Furthermore, male students most likely consumed coffee beverages at schools or academies, but female students consumed them at coffee shops (p<0.01). The reasons male students gave to consume coffee beverages were for scent, taste, fatigue, and to stay awake. Similarly, the reasons female students gave to consume coffee beverages were for scent, taste, habit, and to stay awake (p<0.01). Fully 58.1% of male students and 80.0% of female students ate snacks along with coffee beverages (p<0.01). Most male students substituted a coffee beverage and accompanying snack for a regular meal once a month. Female students were doing it at most 2-3 times a month (p<0.05). The mean daily dietary energy intake of male students was 1,924 kcal/d, and of female students was 1,518 kcal/d (p<0.001), which both were below the estimated energy requirements. Male students obtained 285.6 kcal/d and female students obtained 289.5 kcal/d from coffee beverages and accompanying snacks. There was a significant different in dietary intake of energy (p<0.05), calcium, and iron (p<0.001) for each ratio of reference intake between male and female students. The students who ate larger amounts of coffee beverages and accompanying snacks consumed less dietary energy, protein, calcium, and iron, respectively (p<0.05). These results show that many students consume coffee beverages regularly and obtain large amounts of energy from coffee beverages and accompanying snacks. It also shows that student's dietary nutrient intake tends to be poorer, as he or she obtains more energy from coffee beverages and accompanying snacks. Therefore, it is critical to monitor the influence of consumption of coffee beverages and accompanying snacks on the dietary nutrient intakes and health of college students, and to provide nutrition education about the proper consumption of coffee beverages and accompanying snacks based on scientific evidence.

Living conditions of the rural elderly were assessed in terms of clothing behavior, health and nutritional status, housing and envioronmental condition, and psychological adjustment. The subjects were eighty individuals over sixty residing in the rural community of Iksan-kun, Chollabukdo. The interview method using questionnaires, direct measurement, and observation was used for this study. Data were compared with those obtained from a previous study of the elderly residing in an urban area. Clothing behavior showed that the elderly residing in the rural community were more concerned about plain and conservative design of clothes than their urban counterparts. Special protective clothes for cropdusting with agricultural chemicals had not been prepared. The following urgent needs were pointed out: development and supply of agricultural chemical protective clothing and development and education of appropriate washing and clothing care methods. The health status of the elderly was generally good, but poor eating habits were found more frequently in the rural elderly than among the urban dwellers. Several dietary nutrient intakes were insufficient. Contrasting the urban elderly with the rural group, it was found that the urban group lacked sufficient vitamin A and vitamin C and the urban women had insufficient calorie whereas the rural group was deficient in protein, vitamin A, calorie, and fat. A significant relationship was found between dietary nutrient intake and health index, food habit points, self recognized health status, meal satisfaction, and economic status. Urgent needs of the development of a nutrition education program for the elderly were pointed out. Most of elderly residing in the surveyed rural communities were living alone or with their spouse only, therefore only one room was used among the three or four available rooms. Most of the rural elderly were living either in a traditional Korean house built with differing floor levels or in a modified Korean style house. Minimal modernization had been made for kitchen facilities such as sink and gas range or for heating facilities with the briquette boiler. However, sanitary space such as lavatory and bathroom had not been remodeled. A housing welfare program for rural communities should be implemented at the national level. The comparison of psychological characteristics of the rural elderly with their city counterparts revealed that the rural elderly have a more stable psychological status and optimistic attitude than those living in a city. However, it was found that most of the elderly did not have any future plan. Community programs for the elderly including hobbies or leisure activities or education programs to generate close interpersonal relationships with their children should be developed and provided.

This study was peformed to assess the relationships among bone mineral density(BMD), nutrient intake and lifestyle factors in postmenopausal women. A trained nutritionist examined the interviewed usual dietary intake and physical activity of 85 subjects in Chungnam with a questionnaire interview, and BMDs of the lumbar spines($L_2-L_4$), femoral necks(FN), ward's triangles(WT) and trochanters(TR) were measured by dual energy X-ray absorptiometry (DEXA). The BMDs(T-score) of $L_2-L_4$, FN, and WT were $0.996g/cm^2(-1.601),\;0.697g/cm^2(-1.697)$, and $0.793g/cm^2(-1.512)$, respectively, which were assessed as osteopenia by T-score,. and TR was normal at $0.718g/cm^2(-0.675)$. Subjects included 85 in Chungnam were divided into three groups according to the BMD measurement of the $L_2-L_4$ and FN assessed by T-score. The percentages of the osteoporosis, osteopenia, and normal groups were $32.9\%,\;42.4\%$ and $24.7\%$ respectively. The average age was significantly the highest of the osteoporosis group than in the other two osteopenia or normal groups(P<0.001). Among lifestyle factors, the BMD of lifestyles was significantly related with exercise but it was not significant with medication., salt. intake, bone fracture, coffee consumption, drinking and smoking. The nutrient intake of the subjects was most nutrient intake adequate to the Korean RDA level for most nutrients excepting energy intakes and calcium. The BMD of lumbar spines $L_2-L_4$ showed significant positive association with the intake of most nutrients except carbohydrate, especially in the normal group. The Higher BMD levels were found for those with high intake of protein and vitamin B1. The BMDs of $L_2-L_4$, and FN were positively correlated with showed energy expenditure, exercise, miscellaneous activity, per weekend and week(P<0.05) in normal group but that was showed negatively correlated in the osteopenia group. Therefore, this study confirmed that one of the most effective ways to minimize bone less in postmenopausal women is to maintain an adequate intake of calcium and other nutrients and regular physical activity.

To determine food preferences and nutrients intake of nursery school children, 199 children, ages 1 to 6 years, were assessed with a structured questionnaire completed by their mothers. The questionnaire included questions related to dietary habits, mother's interest in the child's health, family history of diseases, etc. The nutrients intake was measured by 24-hour recall method. Children's weight and height were measured by trained investigators on the same day. For analysis purposes, the subjects were grouped into underweight, normal and overweight groups based on the z-score of weight for height. Only 58.3% of the subjects were grouped into the normal weight group. On the other hand, 19.1% were in the underweight group and 22.6% were in the overweight group. Forty four percent of them showed unbalanced dietary habits such as preference for picky foods, 40.0% of them disliked vegetables, and 46.7% disliked minor grains other than rice. Children in the underweight group showed a higher score of inappropriate dietary habits compared to those of normal or obese groups. The level of nutrients intake of the subjects was higher than the Korean RDA value in general, except for Ca, calories, and Zn. However, 87.4% of the children showed a higher intake level than 125% of KRDA in protein, and 18.2% and 41.4% of them showed a lower intake level than 75% of KRDA in Fe and Ca, respectively. Children in the underweight group showed a higher percentage of eating less than 75% KRDA in niacin compared to those of the normal or overweight group (p<0.05) and we found a similar tendency in Fe, Zn and Vitamin $B_1$ intake.

This study was conducted in order to improve nutritional support based on analysis of the eating habits and training schedule of junior and senior high school fencers. A survey was conducted on 30 fencers (junior boys=9, girls=7; senior boys=4, girls=10) using a questionnaire. Total daily calorie intakes were 2325.7${\pm}$1168.5 kcal (boy), 2344.0${\pm}$786.3 kcal (girl) for junior fencers and 2183.3${\pm}$726.6 kcal (boys), 2654.4${\pm}$1043.6 kcal (girls) for senior fencers. Nutrients below the RDIs were riboflavin and vitamin C for junior boy fencers and vitamin A, riboflavin, niacin, and vitamin C for senior boy fencers. The rates of the participants who had obtained nutritional information were 44.4% (boys) and 14.3% (girls) for junior fencers and 50.0% (boys) and 80.0% (girls) for senior fencers. Approximately half of the fencers had meals twice a day (55.6% for junior boy fencers, 57.1% for junior girl fencers, and 50.0% for senior fencers). The number of the fencers who were interested in nutrition varied: 66.7% and 28.6% of the junior boy and girl fencers answered they were interested in nutrition, while 25% and 60% of the senior boy and girl fencers showed interest in nutrition issues. Recommendations of total calories were 2,874 kcal (boys) and 2,377 kcal (girls) for junior fencers and 3,398 kcal (boys) and 2,375 kcal (girls) for senior fencers respectively. A dietary plan for the fencing players during training periods was designed to improve their health and performance. Athletes can simultaneously refuel and repair their bodies while contributing to their rehydration goals by consuming fluids that are sources of carbohydrates and protein, e.g., flavored milk and liquid meal supplement. Specific sport nutrition education applicable to athletes, especially young athletes, is recommended under professional support. Professionals may then target particular categories of athletes for the development of educational programs aimed at improving growth and athletic performance.

The mother's obesity-related stress and it's association with obesity, food intake, and physical activity in both mothers and their children were determined. Based on self-reports from 470 mothers, obesity stress of mothers were scored by using a five-point Likert scale; only low and high stress scores were used in this study. The perceptions of mothers' weights and their children's weights, mothers' Body Mass Indices (BMI), and preschoolers' Weight-Length Indices (WLI)(%) were also determined. The obesity stress of mothers was significantly associated with the mothers' BMI (high stress: $23.5{\pm}2.4$ vs. low stress: $19.6{\pm}1.7$, p<0.05), but not with their children's obesity. Mothers with a high obesity stress reported a higher percentage of family history of obesity (62.1% vs. 38.3%, p<0.001) than mothers with low obesity stress. Compared to mothers with low obesity stress, mothers with high stress had lower correct-perceptions about their weights (p<0.05) but higher correct-perceptions for their children's weights. Almost 54.5% of mothers with high stress reported watching television 2 or more extra hours per day, compared with 32.2% of mothers with low stress (p<0.05). More children of mothers with high stress had long hours of daily TV viewing than children of mothers with low stress (36.0% vs. 15.3%, $X^2=10.491$, p<0.05). Mothers with high stress reported lower intake of protein-rich foods (p=0.01) and vegetables (p=0.039), but a higher intake of snacks (p=0.009), compared to mothers with low stress. More children of mothers with high stress reported eating high fat snacks or high sugar snacks everyday, but this was not statistically significant. In conclusion, high obesity stress in mothers were greatly associated with their BMI and their inactive life style, including long TV viewing hours per day and unbalanced food intakes, which can lead their children becoming inactive and obese. Special attention is recommended for overstressed mothers and their children, especially those who enjoy long hours of TV viewing.
