The purpose of this study is to examine the relationships among body composition, dietary intake, exercise, and life style in children(M=80, f=102) of the 5th and 6th grades of elementary school. Anthropometry and multifrequency bioelectrical impedance analysis were conducted to estimate body composition. Dietary intake, exercise, and life style were determined by using questionnaires. When obesity was classified greater than 120% of the ideal body weight, the prevalence rates of obesity were 31.2% for boy and 20.6% for girl. There were significant differences in body composition between nonobese(NO) and obese(OB) groups. Mean fat mass(FM) and lean body mass(LBM) were 8.6kg and 27.7kg for NO group and 16.7kg and 32.3kg for OB group, respectively. Also a significant difference was found in hydration rate(TBW/body weight)between groups( <0.01). No significant difference was found I total calorie intake and nutrient intakes between groups. No difference was found in the frequency and duration of outdoor exercise and indoor activities. Mean sleeping hours was 8-9hours for 62% of nonobese children and for 59% of obese children. However, calorie intake per body weight was significantly lower inobese children than in nonobese. The present study showed that significant differences existed in their body size and composition between NO and OB groups , while no differences existed in daily calorie intake, excercise , and life style. This may indicate that important obesity-promoting factors of early onset obesity may rely on other factors such as hereditary or environmental factors besides factors considered. Further studies are required to understand obesity-promoting factors in children. (Korean J Community Nutrition 2(5) : 680∼686, 1997)

Benign prostatic hyperplasia (BPH) is the most common prostate disease in middle aged and elderly men. Therefore, identifying risk factors for BPH is crucial for understanding the etiology and for undertaking interventions or targeting strategies. The survey was carried out in two steps: first, pilot study was conducted prior to the main study in order to estimate baseline characteristics. Second, main study investigated prevalence and risk factors of BPH by clinical diagnostic tests and questionnaire. A total of 641 male aged 50-79 years participated in this community-based cross-sectional study. Using 24 hour recall of food consumption, we found that animal fat intakes increased the risk of BPH with adjusted for age, chronic bronchitis, PSA level, drinking frequency, and excercise frequency (odds ratio 1.84,95% confidence interval 1.10-3.06) . Although BPH has been considered as unavoidable disease with advancing age, if these dietary risk factors are clearly identified, it can be prevented effectively by laying special emphasis on those at risk.

This study was performed to identify nutritional status and eating behaviors of underweight male adolescents aged 15 to 19 years. The subjects selected by using the data of KNHANS-2001 were 32 underweight boys and 135 normalweight ones. We found that weight, waist and hip circumference of the underweight group were significantly different to normal-wight group, but height and waist-hip ratio were not. Their serum indices belonged within normal ranges and showed no difference between the two groups. Their energy and nutrient intakes were mostly poor. The level and proportion of the subjects below EAR, NAR and INQ of each nutrient were not significantly different between the two groups. There were no difference of frequencies of skipping meals, snacking and eating-out between the two groups, either. When comparing frequencies of food intakes, the underweight group consumed significantly more of fermented fishes and less milk than the normal-weight group. And the former had significantly more rest/sleep, no-does and supplementation and less regular excercise than the latter. The underweight group perceived more correct self-images than the normal-weight group and they tried more to increase their body weight during weight control practice (p<0.001). It was concluded that the underweight group showed no different biochemical indices, nutrient intakes, and dietary behaviors to the normal-weight group, but they revealed significantly higher non-active activities like rest and supplementations.

Nutrition education should be an important component of ongoing health promotion for older adults and their caregivers. This is because prevention through sound nutrition and food hygiene practices and regular excercise is the most cost-effective way to reduce risks for and deal with their major health problems. nutritions education services should effectively promote optimum intake and successful self-care. Unfortunately, however relative to other vulnerable groups, nutrition education for older adults has not been systematically developed or evaluated. Usually oder adults care a lot about their health, so this should be a relatively easy group to teach - but their increasing numbers, longevity and great diversity with respect to health, physical, and economic status and educational level present challenges. Some older adults may not perceive they would benefit from nutrition education, so interesting and motivating them is a challenge. The food and nutrition knowledge of older people has been acquired through a lifetime of experience. For most older adults in the Asian region, their sources are restricted by their restricted education, so that their major sources of information have been informal sources, such as television, radio, friends, family, and perhaps newspapers and magazines if they are literature. Nonetheless, dietary advice for older people should build on their existing knowledge and ingrained values. It should provide information useful in daily food selection, and focus on food, not nutrients - the same foods and groups considered appropriate for younger people, with consistent messages as given throughout the population. Attention must also be paid to discovering learning styles in older people. When we teach in schools, the young students are a captive audience resigned to their learning role. Learning by an older adult, however, reflects an effort to meet his or her perceived needs. Therefore, nutrition education should be a positive experience in a non-threatening environment, relaxed and non-competitive, and perhaps even social environment. The messages also need to be practical and achievable. A needs assessment is essential, because our ability to provide the most effective nutrition education will depend on our success in matching the needs, both perceived and unperceived. of this vulnerable group. Therefore, go to the potential older learners to assess their interest and preferences. Nutrition education activities for older adults are widespread, but few have been evaluated. Evaluation is therefore also recommended, particularly when new methods are used. Tips from other countries for giving successful nutrition education will be given, including some examples of applications as attempted in Hong Kong. Research needs will also be described. In conclusion, successful nutrition education for older adults depends on positive needs-based messages. This is may be hard to do, as few good examples are available to illustrate these principles.

This study was carried out with 505(243 boys and 262 girls in the Sungnam area) high school students to investigate the effects of eating behavior and anthropometric variables of weight and height on excercise performance. General characteristics about subjects and eating behavior were surveyed by questionnaire, anthropometric data were collected using two methods. The weight and height of subjects in 1996 were measured, but the same data in 1995 were collected from health records of each student. Body fat content of subjects was measured by BIA(Body Impedance Analysis). The grades of exercise performance, which were evaluated by physical education teachers were collected from records of a physical strength test score of each subject. From these, the following result were found. Groups with different eating behaviors such as skipping meals, overeating, food preference for a specific food(milk, carbonated drink etc.) were significantly different in their weight and height and body fat contents. The growth rate of height in first and second grade boys was significantly higher than that for grade boys. The amount of weight gain from second grade to third grade was significantly more than that of other grades both for boys and girls. The mean of BMI was $21.66\pm{2.95}$ in boy, $21.50\pm{2.62}$ in girls. The percentage of body fat was $24.91\pm{6.55%}$ in boy $34.73\pm{4.88%}$ in girls. Amounts of body fat were significantly increased in third grade. The group with higher fat content and the higher BMI group had lower values of physical strength. And the ability to exercises perform decreased significantly by promotion of grade. The other variables such as degree of concern about weight control and preference of exercise, and frequencies of exercise per week were significant factors in body fat content and physical strength. As a countermeasure for these problems, nutrition and health education must be developed for adolescents and a practical, proper physical activity guidance campaign for them is necessary.

This study was undertaken in order to examine the relationship of control, perceived health status, self efficacy, social support, and demographic characteristics to health promoting lifestyle of nursing students, and to determine factors affecting health promoting lifestyle of nursing students. The subjects were 270 students of a single university in Busan. The instruments used for this study was a survey of general characteristics, health promoting lifestyle (47 items), control(8 items), perceived health status(6 items), self-efficacy(17 items), and social support(18 items). Data analysis was done by use of mean, percentage, t-test, ANOVA, Pearson Correlation coefficients and stepwise regression with a SPSS PC+ program. The results of this study are as follows : 1) The average item score for the health promoting lifestyle was less than 2.43. In the sub-categories, the highest degree of performance was interpersonal relationships (2.94) and the lowest degree was health responsibility(1.93). 2) Students who were older and higher scores in health responsibility and interpersonal support subscale. Students who had higher grade had higher scores in health support subscale. Students who had experienced disease had higher scores in health responsibility subscale. Students who had experienced exercise had higher scores in health responsibility, exercise and nutrition subscale. 3) Significant correlation between control and self-efficacy, self-efficacy and social support was found. 4) Significant correlations was found between most of the subscales and total health promoting lifestyle. 5) Social support revealed significant correlations with total health promoting lifestyle and all subscales of health promoting lifestyle. Control revealed significant correlations with total health promoting lifestyle and self actualization and health responsibility. Perceived health status revealed significant correlations only with the exercise and nutrition subscale. Self-efficacy revealed significant correlation with the total health promoting lifestyle and all subscales of health promoting lifestyle except exercise and nutrition, stress management subscale. 6) Social support was the highest factor predicting health promoting lifestyles of nursing students(31%). Social support, excercise self-efficacy and control accounted for 35% in health promoting lifestyle of nursing students.

This study examined the weight control and food habits in 160 obese children and 191 normal-weight children in 4th, 5th and 6th graders of some elementary schools in Gumi city. Regarding the subjects' self-recognition of their body shape, 27.8% of the normal weight group and 92.5% of the obese group acknowledged themselves to be obese. 58.9% of the normal weight group and 61.0% of the obese group were not satisfied with their own body shape and the difference between two groups was very small, 23.6% of the normal weight group and 87.5% of the obese group have tried to reduce weight. The main causative factor of weight gain that children themselves recognized was a sedentary life style. All the students showed a high rate of irregular and unbalanced diet. The obese children showed a significantly higher rate of skipping meals and eating meals faster than the normal weight children. More obese children disliked exercise, and did less excercise than the normal weight children. There was a negative correlation between the obesity index and the food habit score. In other words, they frequently skip a meals, eat in a hurry and dislike vegetables and dairy products. In addition, there was a positive correlation between the student's BMI and the parents' BMI. Overall, many normal weight children showed a high level of self-consciousness of being obese or underweight. Both groups showed a low degree of satisfaction with their own body shape. Therefore education for the distorted perception of body shape is needed because, even normal weight children have tried to reduce their weight. Obese children should be encouraged to exercise, not skip a meals and eat slowly. They also need a systematic education program on weight reduction and weight maintenance. Moreover, education on a healthy diet, healthy food habits, and healthy body shape are necessary for elementary school children.

This study examined how the participation rates contribute to subjects' outcomes after a nutrition education (once/week) and exercise (3 times/week) intervention program for 12 weeks in 44 obese female subjects. The subjects were divided into two groups: high-participator (HP) or low-participator (LP) groups according to their participation levels based on the median visit value (30 visits out of a total of 48 visits). Daily nutrient intakes assessed by a 24-hour recall, body composition, blood lipid profiles and physical fitness were measured at baseline and after 12 weeks. After the intervention, weight, BMI, percent body fat, and the waist-hip ratio were significantly decreased in the HP group. In addition, the HP group had a greater rates of changes in weight (HP group: -6.6% and LP group: -3.1%, p < 0.01), BMI (-7.0% and -3.2%, p < 0.01), percent body fat (-7.8% and -4.2%, p < 0.05), and waist-hip ratio (-3.1% and -0.4%, p < 0.01) compared to the LP group. Energy-adjusted protein, fiber, potassium, vitamin $B_1$, vitamin $B_6$, and vitamin C were significantly increased in the HP group. The HP group showed a significant increase in HDLcholesterol and a decrease in blood pressure, total cholesterol, LDL-cholesterol, triglycerides, and atherogenic index (AI). While the muscle endurance, muscle strength, power, agility and flexibility were significantly increased in the HP group, agility and balance were improved in the LP group. In addition, dietary behavior score was significantly increased and stress score decreased in the HP group compared to the LP group. High participation rates were correlated with the improvement of the nutrient density (protein, fiber, potassium, Vitamin $B_1$, Vitamin $B_2$, Vitamin $B_6$ and folate), anthropometric parameters (body weight, BMI and percent body fat), serum lipid profiles (HDL-cholesterol, Triglyceride, and AI) and physical fitness (muscle endurance) adjusted for age, menopausal status, alcohol drinking, nutritional supplement use and baseline BMI. Our results suggest that high participation in nutrition education and exercise program was effective not only for weight reduction but also for the improvement of physical fitness in obese women.

This study was conducted to identify the factors associated with weight control and nutritional knowledge of juvenile delinquents. The average heights of the subjects in this study were 172.20 cm (male) and 160.89 cm (female), and the average weights were 66.73 kg (male) and 58.42 kg (female), and the BMIs (Body Mass Index; $kg/m^2$) were 22.46 (male) and 22.54 (female). The results of this study revealed that 41.4% of the subjects were over weight or obese. In addition, there were significant differences in the BMI, satisfaction with body image and perception of body image observed between male and female subjects. Furthermore, female subjects were more experienced at weight control than male students (p<0.001). Additionally, overweight and obese individuals had more experience with weight control than subjects that were not overweight. Moreover, there were significant differences in the reason that subjects took weight control measured between male and female students. Specifically, female subjects practiced weight control due to their appearance (p<0.001). The order of methods by which male subjects attempted to control their weight was exercise>diet control>starvation and for girl student were diet control>starvation>excercise. The nutritional knowledge scores were higher for female subjects than for mele subjects. In addition, the nutritional knowledge scores increased as the BMI value increased and the $father^{\circ}{\emptyset}s$ educational level increased. These results of this study could be useful data to plan and develop nutritional education programs for juvenile delinquents.
