  • This study was conducted to assess dietary intake and quality obtained by 24-hour recall method between Korean-Chinese in Yanbian, China(Korean-Chinese) and Koreans in Kuri, Korea(Koreans). The subjects consisted of 730 Korean-Chinese and 696 Koreans. Mean daily energy intake of Korean-Chinese was 1,788kcal and that of Korean was 1,844kcal. Proportions of energy intake from carbohydrate, fat, and protein were 62.6: 16.9: 14.2 for Korean-Chinese and 65.4: 16.3: 14.4 for Koreans. Nutrient intake levels of Koreans were higher than those of Korean-chinese in most nutrients. Calcium and vitamin $B_2$ intakes as percent of Korean RDA were less than 60% in Korean-Chinese. Koreans consumed calcium and vitamin A in the level less than 80% of Korean RDA. Iron intake level of Korean females was less than 75% of Korean RDA. Korean-Chinese consumed 90.4% of food from plant origin, and Koreans consumed 82.5% of food from plant origin. Mean dietary diversity score(DDS) of Korean-Chinese, $3.00{\pm}0.39$, was significantly lower than that of Koreans, $3.73{\pm}0.76(p<0.05)$. Mean dietary variety score(DVS) of Korean-Chinese, 13.6, was significantly lower than that of Koreans, 20.1(p<0.001). According to these results, some adults in the both Korean-Chinese and Koreans did not consume enough nutrients, especially calcium and vitamin $B_2$ intake for Korean-Chinese and calcium and vitamin A intake for Koreans. Dietary qualities of Korean-Chinese subjects and Korean females were not adequate. In the future, further research to promote dietary quality of Koreans including Korean-Chinese must consider the results of this study.

  • To establish a basic cohort which can survey the nutrient and food intake related to the health status of the middle and old-aged vertically, a longitudinal survey of 110 adults over forty years old was conducted three times in Chon-ju city over 5 years (1994-1999), and the influences of health status by changes in their nutrient and food intake were examined in this study. The results were as follows ; The number of subjects was 110(43 man, 67 women), 10.0% in their forties, 28.2% in their fifties, 45.4% in their sixties 6.4% over seventy, and their average age was 61.4. There were decrease of height about 1cm , increase of body fat % and few changes of BMI during the testing period. As the subjects were aging, the percentage of anemia increased, but averages of blood pressure and blood glucose(men : 91.8mg/㎗, women : 90.3mg/㎗) were constant. Total cholesterol increased from 196.7mg/㎗ to 212.6mg/㎗(P 0.05) over five years, and the numerical values for women were higher than that of men. In many cases, lack of nutrient intake was shown, as compared with the Recommended Dietary allowance(RDA) especially calcium and vitamin A(71.7%, 64.9% of RDA). Grains intake showed a tendency to decrease(P 0.01). On the contrary, fruit intake showed a tendency to increase(P 0.001). On whole meal, plant foods were 85.1% and animal foods were 14.9%. As dietary factors influencing health status were investigated, blood glucose was influenced by vitamin B$_2$, potatoes and triglyceride, DBP and SBP were affected by vitamin B$_1$, vitamin C, legumes, fishes, triglyceride and age. Total cholesterol was under the influence of triglyceride, milk, seeds and fat. BMI was influenced by iron, SBP, animal food, and age.

  • Vitamin E has been applied as a dietary supplement or post mortem to meat cuts to preserve meat quality and extend shelf life. This study was conducted to determine the effects of supplementation of the diet of Hanwoo steers with Economas $E^{(R)}$, a less expensive alternative to vitamin E, on meat quality preservation. To accomplish this, 36 Hanwoo steers were randomly allotted into three treatment groups ; no additive (control), Economas $E^{(R)}$(T1) and vitamin E (T2). Vitamin E and Economas $E^{(R)}$ were included in the diets at 500 mg/head and 200 mg/head, respectively, for 5 months. Evaluation of carcass performance parameters immediately after slaughter revealed no treatment effects (P>0.05). Samples collected from the loin area and stored at $4^{\circ}C$ for up to 9 days showed that T1 and T2 preserved pigment and lipid stability as indicated by significantly (P<0.05) higher CIE $L^*$ and lower CIE $a^*$ and CIE $b^*$ values and a less rapid increase in thiobarbituric acid reactive substance (TBARS) relative to the control. However, treatments had no effect (P>0.05) on cholesterol and fatty acid content in meat. Based on these findings, Economas $E^{(R)}$ provided at 200 mg/head is as effective as vitamin E applied at 500 mg/head at preserving Hanwoo meat quality over a 9 day storage period at $4^{\circ}C$.

  • The purpose of this study was to investigate nutrient intake and food behavior according to the nutrition knowledge of middle school students residing in Seoul and Kyunggi-do, Korea. Anthropometric measurements and questionnaires, including 24-hr recall of dietary intake, were collected from 543 male and female middle school students. They were assigned to one of five groups according to their nutrition knowledge : very high group (VHG ; 90 - 100 score), high group (HG ; 80 - 90 score), normal group (NG ; 70 - 80 score), low group (LG ; 60 - 70 score) and very low group (VLG ; < 60 score), and comparisons were made. The mean age of the subjects was 13.7 years old. The mean height, weight, and BMI of male and female students were 161.9 cm, 52.6 kg and 20.2 kg/$m^2$, 157.0 cm, 50.4 kg, and 20.4 kg/$m^2$ respectively. Female students skip breakfast and dinner more frequently than male students do. Male students skipp lunch and eat fast foods more frequently than females do. Protein, calcium, vitamin B$_1$, vitamin B$_2$, niacin, vitamin C, fat, and animal protein intakes in females are shown to be related to their nutrition knowledge. Calcium, protein, animal protein, vitamin B$_2$and niacin intakes are significantly lower in the VLG than in the others. However, vitamin B$_1$and vitamin C intakes are significantly lower both in VHG and VLG. Fat intake in VHG is lowest. Nutrition knowledge of male students is correlated with mothers knowledge, nutrition attitude and nutritional status. On the other hand, in female students, nutrient consumption was lowest in subjects whose nutrition knowledge was highest and lowest. Therefore, nutrient consumption is affected by nutrition knowledge. However, in female students, possibly due to wrong information on diet or prejudice and outlook, nutrient consumption was low even when they scored high in nutrition knowledge. In conclusion, nutrition knowledge of male students is affected by the mothers nutritional knowledge and attitude. Therefore, nutrition education for mothers is very important. In male students, as their nutrition knowledge is low, their nutrient consumption is affect. These results indicate nutrition education and correct information for body image, balanced diet, regularity of meals and food selection for middle school students are required at both school and home.

  • The prevalence of atopic dermatitis (AD) continues to increase in the industrialized countries related to Western lifestyle and dietary patterns. The purpose of this study was to evaluate the nutritional status, dietary patterns and dietary quality of AD patients. AD patients (n=50) and gender age matched healthy control (HC) were studied in case-control clinical trail. Preference and frequencies of consumption for 98 foods were estimated by questionnaires. Dietary pattern, current nutrients intake, and dietary quality were evaluated by the 3-day food records. As a result, anthropometric measurements from HC and AD patients were not significantly different. AD patients had significantly lower preference for buckwheat, some fishes (shellfish, flatfish, salmon), egg yolk, some vegetables (onion, garlic, Chinese-cabbage, radish, pepper, mushroom), coffee, and snack than those of HC had (p<0.05). AD patients had significantly lower frequency for pea, some fishes (shellfish, herring, flatfish, salmon, codfish), egg, some vegetables (spinach, pumpkin, mushroom), margarine/butter, nuts, coffee and apple juice, fried chicken, coke than those of HC had (p<0.05). The intake of vitamin $B_1$, vitamin $B_2$ (p<0.05) and vitamin E (p<0.001) of AD patients were significantly lower than those of HC. The intake for Ca and Zn of AD patients were remarkably lower than RDA for each nutrient. Moreover, AD patients' index of nutritional quality (INQ) and nutrient adequacy ratio (NAR) of vitamin E, vitamin $B_1$, vitamin $B_2$ were lower than those of HC. AD patients' dietary quality including dietary diversity score (DDS), dietary variety score (DVS), DMGFV (dairy, meat, grain, fruit, vegetable), dietary quality index (DQI) was poor. This results indicate that atopic dermatitis patients had significantly different food preference and food frequency when these were compared with those of healthy people. The dietary diversity, dietary variety and dietary quality of atopic dermatitis patients were very limited.

  • 24-hour recall is the dietary assessment method most frequently used to evaluate dietary intake; however, accuracy is an issue when using this method, especially in large-scale studies. The purpose of this study was to assess the validity of dietary intake estimation using one serving size. Estimates of energy and nutrients taken in over a 24-hr period based on actual intake amount (24HRAI) and based on estimates of one serving size (24HRSS) were compared. Data were analyzed using a paired t-test, Pearson's correlation coefficients, and a cross-classification method. In male subjects, intake levels of energy, fat, vitamin C, vitamin $B_1$, Zn, and total food measured using 24HRAI were significantly higher than those measured using 24HRSS. In female subjects, intake of carbohydrates, fiber, fat, vitamin A, vitamin C, vitamin B complexes, various minerals, and total food measured using 24HRAI were significantly lower than those measured using 24HRSS. Energy-adjusted Pearson's correlation coefficients revealed that intake of all nutrients showed a significant positive relationship between the two measurement methods in both males and females. Cross-classification analysis revealed that 50.5~67.6% of women and 40.3~71% of men were classified in the same quartile of intake of each nutrient when comparing data from 24HRAI and 24HRSS. We conclude that using one serving size in 24-hr recall analysis was valid and therefore may be used in studies to assess food consumption in the general adult population. Also, this method can be used to classify energy and nutrient intake into quartile, which is useful in examining the association between diet and chronic diseases.

  • This study investigated the effects of the nutrition education and exercise program on body composition, dietary intakes and physical fitness in obese women. The subjects were 44 obese women (BMI${\geq}$ 25 kg/$m^2$) who had been participating in nutrition education (1 time/week) and exercise program (3 time/week) for 12 weeks. Nutrition education was focused on low energy, high protein and low carbohydrate diet to reduce the body weight and improve the diet quality. To evaluate the effectiveness of the program, daily nutrient intakes were assessed by 24-hour recall method. Body composition, blood lipid profiles and physical fitness test were assessed before and after the intervention. After the intervention, body weight, BMI, percent body fat, soft lean mass and waist/hip ratio were significantly decreased (p < 0.001). Fasting blood sucrose, total cholesterol, LDL-cholesterol and atherogenic index (AI) were significantly decreased (p < 0.001), while HDLcholesterol was significantly increased (p < 0.001). Energy adjusted protein, fiber, vitamin A, vitamin $B_2$, vitamin $B_6$, vitamin C, vitamin E, niacin and folate were significantly increased. After the intervention, the muscle endurance, muscle strength, agility, balance were significantly increased. The changes in obesity indices (body weight, BMI, percent body fat, waist-hip ratio) were correlated with the changes of the nutrient intakes, serum lipid profiles, physical fitness. These results show that nutrition education and exercise program was effective not only for weight reduction but also for the improvement of physical strength and cardiovascular disease risk factors in obese women.

  • This study was conducted to investigate the anthropometric data, nutrient intakes and serum profiles in premenopausal and postmenopausal women living in Gyeonggi-do Province, Republic of Korea. The subjects were 49 premenopausal women and 63 postmenopausal women who are not taking any hormone or cardiovascular drugs. Anthropometric measurements were taken by a trained practitioner and the data for dietary intakes were obtained by a 24-hour recall method. Serum samples were collected and analyzed for the total cholesterol, triglyceride (TG) and lipoprotein fractions. The mean age of the premenopausal women was $45.17{\pm}3.28$ years and that of the postmenopausal women was 2$62.5{\pm}4.14$ years. The height and weight were $157.86{\pm}$4.35 cm, $58.75{\pm}6.01$ kg in premenopausal women and $156.42{\pm}3.62$ cm, $57.63{\pm}5.38$ kg in postmenopausal women, respectively. WHR (waist hip ratio) in postmenopausal women was significantly higher than that of premenopausal women (p<0.05). There were no differences between the pre-and postmenopausal women in the intakes of energy, protein, fat, Ca, Fe, vitamin A, vitamin $B_1$, vitamin $B_2$, niacin, vitamin C and vitamin E. However carbohydrate and Na intakes in postmenopausal women were significantly higher than those of premenopausal women. In postmenopausal women, Ca intake was below and Na intake was extremely high considering KDRIs (Dietary Reference Intakes for Koreans). Serum triglyceride in postmenopausal women was positively correlated with age, BMI (body mass index) and WHR. Serum total cholesterol and triglyceride in postmenopausal women showed significantly negative correlations with fiber intake. These results suggest that it is necessary to help postmenopausal women maintain a healthy body weight. Postmenopausal women needs to increase Ca (calcium) intakes and diet quality by decreasing the intakes of Na (sodium). In addition, an adequate intakes of fiber is recommended for postmenopausal women to prevent cardiovascular disease.
