The purpose of this study was to provide information on obesity assessment for Koreans. Among total of 1012 research papers enlisted in the Korean J Community Nutrition form 1996 to 2011, 248 articles were examined in which subjects were divided into more than 2 groups by obesity rate. About the method of anthropometric data collection, more than half of the research papers examined 52.5% and 28.7% of studies utilized the directly measured data and self-described data, respectively. About the utilization of obesity assessment methods, indirect methods of weight-height index (BMI, BMI percentile, and Rohrer index) and PIBW (WLR, Broca index, and KDA) were 62.4% and 23.2%, respectably, and the direct method of percent body fat assessment was only 9.3%. The most frequently utilized methods were WLR in under primary and primary school children, and BMI in the middle and high school students and in adults. For primary school students, WLR was the most frequently utilized method up to 2007, but it changed to BMI percentile afterward. Broca Index was no longer utilized since 2008. There were no articles utilizing BMI percentile and Rohrer index for obesity assessment in adults. Criteria for obesity assessment were not consistent among research papers: for example, % body fat, 19~40%; BMI, 20~30; BMI percentile, 85th or 95th. In the case of PIBW, 120% of ideal weight was the most frequently utilized criterion for obesity. Based on these findings, we suggest that proper methods and criteria of obesity assessment for each age group should be determined and proclaimed.

OBJECTIVES: New retinol activity equivalent (RAE) was introduced as vitamin A unit in Dietary Reference Intake (DRI) for Koreans 2015. The purpose of this study was to evaluate the adequacy of 2015 reference intake (RI) of vitamin A in RAE unit by the comparison with RI and dietary intake of vitamin A. METHODS: Analyses on RI of vitamin A were based on the Recommended Dietary Allowances (RDA) for Koreans (1962~2000) and DRIs for Koreans (2005~2015). Analyses on Koreans dietary intake of vitamin A were based on the Korea National Health and Nutrition Examination Survey (KNHNES) reports (1969-2014). For recalculation of RI and dietary intake of vitamin A in RE to RAE, 2013 Koreans intake of retinol: carotenoids ratio of 13: 87 was applied. RESULTS: RI of vitamin A was 600~750 RE for Korean adult, and 339~425 RAE when calculated by applying the retinol and carotenoids intake ratio. Vitamin A intakes of Koreans were <100% RI, 267~668 RE from 1969 to 2001. From 2005, vitamin A intake had increased to >700 RE, >100% RI. When vitamin A intake was converted from RE to RAE (2005~2014), 718~864 RE became 405.8~488.1 RAE, decreased to 56.5% level. The recent 2015 RI of vitamin A is 850 RAE, two times of 2005 & 2010 RI of 425 RAE for adult male. CONCLUSIONS: When nutritional status of vitamin A was assessed for Koreans using the estimated average requirement (EAR) of 2015 (570, 460 RAE for male, female adults, respectively), ratio of deficient people increased significantly when judged based on the previous intake of Koreans, <490 RAE. We needs to examine the 2015 RI (EAR) of vitamin A, find a way to measure the accurate intake of dietary vitamin A, and to increase the dietary intake of this vitamin.

OBJECTIVES: Recommended Menu (RM) prepared according to the Target Pattern expected to meet the dietary reference intake (DRI) of nutrients. Nutritional adequacy of RM in ‘DRI for Koreans 2015’ were analyzed to verify whether such expectation was fulfilled. METHODS: Dishes in RM are categorized by 5 food groups, and number and types of dishes for main meal and between-meals were analyzed. The energy and 12 nutrients (protein, dietary fiber, Ca, P, Fe, Na, K, vitamin A, thiamin, riboflavin, niacin and vitamin C) contents in 10 RMs were calculated using the food composition table (CD) in ‘DRI for Koreans’. Energy, energy contribution ratio, and nutrient contents in 10 RMs for 18 age groups were evaluated based on the ‘DRI for Koreans 2015’. RESULTS: Number of dishes per meal were 4.83, and representative table setting consisted of cooked rice + soup (or stew) +3 side dishes. Energy contents of RM were 75~109% of estimated energy requirement (EER). None of the RM met the DRI of all 12 nutrients examined. Calcium was the most insufficient nutrient. Only 1-2 years' RM met the DRI, all the other RMs did not meet the calcium DRI. Dietary fiber and potassium contents were also insufficient in most RM. In adult male's RM, only 1 nutrient, i.e. calcium did not meet the DRI, but in female adult's RM, 5~6 nutrients did not meet the DRI. Energy contribution ratio of carbohydrate, protein, and fat in RM were 59.0~70.4%, 15.7~17.5%, 12.1~23.5%, respectively. And 4 RMs out of 10 exceeded the upper limit of acceptable macro-nutrient distribution range (AMDR) of carbohydrate and 3 RMs out of 10 RM were below the lower limit of fat AMDR. Contribution ratio of nutrients were ≥ 40% by food groups were as follows: grain group in energy and carbohydrate; meat·fish·egg·legume group in fat, protein, and niacin; vegetables group in dietary fiber, vitamin A, and vitamin C; milk·dairy products group in calcium. CONCLUSIONS: RM prepared according to the Target Pattern did not meet nutritional adequacy as expected. Especially calcium, potassium, and dietary fiber contents are needed to be increased in many RMs. Further, energy content in RM needs to be adjusted for fat·sugar food group assigned in Target Pattern and condiment.

It is important to prepare and execute the menu plan for proper and balanced intake of nutrients in the adolescence. This study investigated the new approach for planning menu by ordinary meal pattern based on cooked foods groups. The amounts of cooked foods in the menu plan assumed to be single serving size. The middle school second graders participated for the study. A total of 313 questionnaires were analyzed using CAN-pro 3.0 and SPSS WIN 12.0 program. The average content of energy in the menu plan was 2,453 kcal, the average ratios of energy contribution by carbohydrate, protein and fat were 54.3%, 17.9%, 27.8%, respectively. A total of 56.9% menu plans (94.9% of male and 8.7% of female students') were below the lowest limit of optimum carbohydrate energy ratio of 55%. A total of 29.1% menu plans (33.1% of male and 23.9% of female students') were exceed the highest limit of optimum fat energy ratio of 30%. The NAR of minerals and vitamins were all 1.0 except for calcium (0.92) and folate (0.88). When INQ of the individual cooked food groups were calculated, kimch was the highest in all minerals and vitamins examined, suggesting that kimch may be the best source for all minerals and vitamins, including calcium and folate with the minimum change in energy content. In conclusion, the menu plan by ordinary meal pattern in this study was low in carbohydrate, high in fat, and contained enough minerals and vitamins except for calcium and folate for middle school students.

Traumatic dislocation of the testis occurs when a normally distended testis assumes, as a result of trauma, a non-scrotal position by passing along fascial plane and through normal anatomic aperture. Less than 50 cases of true traumatic dislocation have been reported. The etiology, classification and treatment of testicular luxation are reviewed briefly. If efforts at closed reduction are unsuccessful, management requires surgical exploration and orchiopexy. The prognosis for recovered or fertility potential after this repair of dislocation of the testis is good. We report the case that one testis has traumatic dislocation with a ruptured vas deferens and the other has a primary spermatogenic defect.

The purpose of this study was to find out the information on nutrition labeling and how many calories and nutrients the high school students consumed for 1 day from cookies. A total of 74 male and female high school students in Suwon were surveyed and 56 cookies that they consumed were examined. Background data were collected by questionnaire, cookie intake by 24-hr recall, and the calories and nutrients content in cookies and the amount of intake by nutrition information on the wrapping paper of cookie. The statistical analysis for the data was done by SPSS 12.0. Energy contents in 1 serving size of cookie were 90~315 kcal, average of 170 kcal. The protein contents were 0~7 g, fat 2~20 g, cholesterol 0~55 mg, and sodium 30~390 mg in 1 serving size of cookie. Most of the cookies (80%) examined contained no trans fat at all, which is desirable. Among the types of cookies, snacks contained higher quantities of calories and sodium, the pie contained more sugar and cholesterol, and the biscuit had more trans fat. One fourth of the cookies examined belonged to 'high calorie, low nutritious food' according to the criteria proposed by The Ministry for Health, Welfare and Family Affairs. Thus the excessive intake of cookies might result in nutritional imbalance. There were large differences in calorie intake among students, from zero who did not intake any cookies at all to maximum 818 kcal/day, an average of 75 kcal/day. When the students who did not intake cookies were excluded, energy 205 kcal. fat 10g, sodium 177mg were consumed from the cookie for a 1 day on average.

This study examined the state of health and weight maintenance according to the body mass index (BMI), and explored demographic variables, diet variables, the degree of stress etc. The results presented were based on data collected from 428 women who are mothers of the middle school children in Jeongeup city. Using SPSS WIN (Ver 9.0), the frequency, percentage, mean, standard deviation, chi-square, ANOVA, and correlation analysis were provided. The mean of BMI for the subjects was 22.6, the ratio of obese women (BMI > or = 25) was 22.9%. The frequency of the reported circulation or respiratory related diseases was greater in the obese group compared to the normal weight (20 < or = BMI < 25) or the lean (BMI < 20) groups. The obese group had less awareness of obesity. Those who regard themselves obese had lower rates of satisfaction with their body shape and higher rates of interest in weight control. Approximately 65% of the subjects attempted weight reduction more than once. Subjects who were obese had the most undesirable dietary behavior. In particular, this group had the higher rates of rushed meals, overeating, meals while watching TV or newspapers, and snacking, and eating out. In analyzing the correlation of variables influencing obesity, there were positive correlations between obesity and overeating, obesity and the degree of stress. Correlations between obesity and satisfaction for life found to be negative. Moreover, stress had a positive correlation with obesity and overeating, and showed negative correlation with eating behavior. Consequently, stress seemed to induce undesirable eating behaviors and increase obesity. Of the demographic background variables, subjects who were obese tended to be older, had lower levels of education, higher rates of employment, longer period of marriage, the higher number of children, preschool children or children preparing for highschool or college, lower satisfaction with children and household life.

The purposes of this study are to assess the diet and nutritional states of elementary and middle school students in the Daegu area by using nutrition quotient (NQ) for children. A survey was conducted with 366 elementary school students and 364 middle school students. Elementary school students showed higher total NQ scores (66.2) than middle school students (58.3), without gender difference. Elementary school students showed higher NQ scores in all 5 domains (balance, diversity, abstinence, regularity, practice) than middle school students. As for gender difference, boys showed higher scores than girls in balance and diversity, and girls showed higher scores in abstinence than boys. When scores of 5 domains were evaluated as good or bad, the percentage of good was highest in abstinence (63.4%) and lowest in diversity (22.9%). The percentage distribution of NQ of 1st (excellent) to 5th (bad) grades were 8.4%, 13.6%, 44.5%, 19.3%, 14.2%, respectively. In the 1st grade, there were 9.5%p more elementary school students, and in the 5th grade, there were 11.6%p more middle school students. No gender differences were found in the distribution of the NQ grades. Since NQ for children presents a convenient method of evaluating the diet and nutritional states of many subjects simply and simultaneously, a follow-up study will hopefully revise and supplement the question items and standards of judgement by the age groups.

OBJECTIVES: The objective of this study was to revise the target pattern in food guidance system for adolescents' balanced menu planning. METHODS: The food groups in the target pattern were divided into detailed food items, and intake number were assigned to each food items based on the revised standard food composition table. The validity of revised target pattern was examined. Menu planning according to the revised target pattern was made available to 305 male and female middle school students and the nutritional assessment of the menu plan were carried out using SPSS WIN 12.0. RESULTS: The energy contents, energy contribution ratios of carbohydrate, fat, and protein, and 4 minerals' and 6 vitamins' contents of the revised target pattern were adequate. The average energy contents of the menu planned according to revised target pattern were 400~500 kcal higher than that of the revised target pattern when the revised standard food composition was applied. The energy contribution ratios of fat were 28.9%, close to maximum of acceptable macronutrient distribution range (AMDR) (30%), and that of carbohydrate were 54.5%, lower than minimum of AMDR (55%). The nutrient adequacy ratios (NARs) of calcium and vitamin C were less than 1.0. According to index of nutritional quality (INQ) of food items, kimchi, milkdairy products, and soybean curd were energy efficient source for calcium, kimchi, fruit, vegetable and seaweed were energy efficient source for vitamin C, with INQ of food items were higher or close to 2.0. Kimchi was the best energy efficient source of calcium and vitamin C. CONCLUSIONS: Revised target pattern based on the adolescent's foods intake was not good enough for balanced menu planning by adolescents, because what they ate and what they wanted to eat were very much different. Detailed guidance for food selection is necessary in each food items.

OBJECTIVES: Maintaining a balanced diet and thus health is crucial for adolescents, and the first step for balanced diet practice is meal planning. Adolescents, however, find it difficult to plan their meals. This study thus was set out to design an easier way of planning meals for adolescent girls. METHODS: A dish-based target pattern for adolescent girls was tabulated, and validity of this was examined. Meal plan applying a dish-based target pattern was prepared by 150 female middle school students, and nutritional adequacies of those meal plans were examined. Validity and adequacy were tested by energy content, energy contribution ratio, nutrient adequacy ratio (NAR), probability of nutrient inadequacy, index of nutritional quality (INQ) calculation. RESULTS: A dish-based target pattern with 11 dish groups was validated for nutritional adequacy. Though the NAR of calcium was 0.96, the INQ of calcium was 1.00. The average energy supply from the meal plans was 2,379 kcal, higher than the estimated energy requirement of a female middle school student, but the energy contribution ratio of carbohydrates, proteins, and fats were all adequate according to the acceptable macronutrient distribution range (AMDR). NAR of all nutrients examined were 1.0, except for calcium. The NAR and INQ of calcium were 0.87 and 0.75, respectively, and the meal plans at risk for calcium inadequacy was 19.30%. CONCLUSIONS: A dish-based target pattern proposed for adolescent girls was valid, but the meal plan prepared by female middle school students using this approach was high in energy and low in calcium supply. To cut down the energy supply from the meal plan, it is necessary to recommend dishes low in fat and use low fat cooking methods. To increase the calcium supply, it is important to recommend seaweed and legume group dishes with higher Ca INQ food items.
