A survey on the nutritional state was conducted from June 11 to Nov. 30, 1971, on 673 women workers $(16{\sim}25\;yrs)$ Jorking in a factory of food industry. Total body fat content was measured by skin-fold thickness (S. F. T.) with caliper at three region of the body. And it was calculated by regression equation, with the following conclusions were abtained. 1. The mean with standard deviation body height and weight of the Korean women workers were $155.0{\pm}4.21\;cm$ and $50.1{\pm}5.31\;kg$; respectively. 2. Their mean skin-fold thickness with their standard deviation triceps region of upper arm, 14.3{\pm}3.42$; Subscapular region, $18.0{\pm}5.57mm$; Abdominal region, $19.3{\pm}4.87mm$ and total aveager, 17.2{\pm}3.91mm$. 3. The body fat contents according to body fat weight regression equation were;fat weight. 10.7 kg; fat-free weight, 39.4kg; fat weight/ fat-free weight, 27.5%; fat-free mass/ total body mass 77.6%, and fat weight/ total body mass,21.6%. 4. Since the sknin-fold thickness between the triceps and upper abdominal region and between the former and Subscapular region were correlated with the coefficients of 0.838 and 0.615 respectively. and the following regression equations were established. a) S. F. T. of Subscapular region $(mm)=0.929{\times}$S. F. T. of triceps region (mm)+4.707. b) S. F. T. of Abdominal $region(mm)=1.24{\times}$S. F. T. of triceps region(mm)+1.50. Nutritional survey on the women workers in a fact ory of food industry, performed as above by the S. F. T. method, elucidated the fact that their nutritional state is as good as the control healthy female, and that their energy uptake may well be said to be satisfactory.

This study aimed to assess the nutritional quality of breakfast among Korean school-aged children and adolescents depending on eating together as a family, based on the 2013-2014 Korea National Health and Nutrition Survey. One day 24-hour recall data of 1,831 children and adolescents aged from 6 to 17 years were collected. The nutritional quality of breakfast was analyzed and compared between Family Breakfast Group (FBG, n=1,410) and Eating-alone Breakfast Group (EBG, n=421). The results showed that age, family structure, number of family members, and frequency of breakfast were associated with eating breakfast as a family. The calorie intake from breakfast explained 19% and 16% of the daily intake for FBG and EBG, respectively. The percentages of children and adolescents consuming Vitamin A, Vitamin $B_1$, Vitamin $B_2$, Vitamin C, Niacin, and Iron less than 1/4 of the Estimated Average Requirements were significantly lower in FBG than in EBG. The average numbers of serving for "Grains" and "Vegetables" food groups and the average Dietary Diversity Score were significantly higher in FBG than in EBG. Overall, the results indicated that eating breakfast as a family is positively associated with nutritional quality of breakfast among Korean school-aged children and adolescents.

BACKGROUND/OBJECTIVES: In a healthy person, from 35 years of age, there is an annual loss of muscle mass at the rate of 1-2% and is associated with a decline in the quality of life. This study aimed to identify the particular dietary patterns associated with the risk of lower lean muscle mass in Korean postmenopausal women. SUBJECTS/METHODS: The Korea National Health and Nutrition Examination Survey (KNHANES) is a population-based, continuous cross-sectional annual survey. The participants of the KNHANES IV (2008-2009) and V (2010-2011) were considered for this study. The study sample consisted of 1548 postmenopausal women, aged 45-86 years. Lower lean muscle mass was defined as having appendicular skeletal muscle mass corrected for body weight less than 1 standard deviation of the young reference group aged 20 to 39 years in KNHANES IV and V. To identify the dietary pattern using factor analysis, 24-h recall data was used. RESULTS: The prevalence of lower lean muscle mass was 31.3% in this study population. Four dietary patterns were identified by factor analysis; 'Diverse', 'Western', 'Traditional', and 'Snacks and beverages'. The 'Western' pattern, highest factor loadings for flour and bread, potatoes, red meat, processed meat, eggs, and cheese, was significantly associated with a high (60%) risk of lower lean muscle mass (odds ratio [95% confidence interval] = 1.60 [1.07-2.39], P for trend = 0.01) after adjustments for potential covariates. The other 3 dietary patterns were not associated with lower lean muscle mass. CONCLUSIONS: The study findings suggest that the 'Western' dietary pattern that includes flour and bread, potatoes, red meat, processed meat, eggs, and cheese, may be associated with a higher risk of lower lean muscle mass in Korean postmenopausal women.

The purpose of this study was to investigate food habits, nutritional knowledge, nutritional risk factors, health-related lifestyle, health status and dietetic therapy in Korean middle-aged and elderly outpatients taking supplements. A cross-sectional survey was conducted from July to December in 2001. Subjects were 1702 (male 731, female 971) age-related chronic disease outpatients aged over 50 years. Data was collected using a standardized Questionnaire by in-person interview and analyzed by SPSS system. The subjects with supplement had significantly lower nutritional knowledge, higher nutritional risk factors, undesirable lifestyle, and lower self-reported health status compared to those without supplement. However, the subjects with supplement had desirable (cod habits and more concern about health compared to those without supplement. Age-related chronic disease group with supplement had significantly undesirable food habits, lower nutritional knowledge and higher nutritional risk factors compared to control group with supplement. Age-related chronic disease group without supplement had significantly desirable food habits, higher nutritional knowledge, lower self-reported health status and higher stress compared to control group without supplement. Therefore, these results may provide basic information for proper supplement of Korean middle-aged and elderly outpatients.

The objective of the present study was to determine the prevalence and type of nutritional ergogenic aids use, and to determine the frequency, reasons for use of nutritional ergogenic aids. Thirty-four male bodybuilders (mean age = 27.0 years), twenty-four male weight lifters (mean age = 20.9 years) participated in the study. Participants completed a comprehensive survey detailing their usage patterns. In this study, 78.1% of bodybuilders and 79.2% of weight lifters reported using nutritional ergogenic aids. The most frequently taken nutritional ergogenic aids, in ranking order, were protein/amino acid powders (79.4%), multivitamin/minerals (67.7%) and creatine (67.6%) for bodybuilders, in contrast to sports drinks (100.0%), protein/amino acid powders (50.5%) and creatine (50.5%) for weight lifters. Over the half of the respondents, 79.4% of bodybuilders and 50.6% of weight lifters, used protein/amino acid powders to gain muscle mass and to stay healthy. Bodybuilders, 67.6% and weight lifters, 41.7%, used multivitamin/minerals to stay healthy and for energy. The intakes of most vitamin and minerals through diet and nutritional ergogenic aids were much greater than RDA. Vitamin $B_1$, vitamin $B_2$, niacin, vitamin $B_6$ and folate intakes were ranged at 400-900%. Vitamin C intake was 1285.4% (for bodybuilders) and 1322.6% (for weight lifters). The correct answer rate of nutritional ergogenic aids was 46.0% for bodybuilders and 52.0% for weight lifters. Both bodybuilders and weight lifters took highly nutritional ergogenic aids and it tended to be taken irrespective of scientific background. Specific sport nutrition education applicable to athletes, especially strength athletes, is recommended. The findings of this investigation could be used to enable the professionals (sports dietician and physician) to identity common misconceptions regarding nutritional ergogenic aids and to implement educational programs.

The purpose of this study was to survey the concern for health, nutrition knowledge, and nutritional attitude of the elementary school children's mothers, to investigate the correlations among them, and to estimate their effects on the growth of their children. The questionnaire was answered by 780 mothers in the Busan area. The concerns over health and nutritional attitude were above average in all items. The perception and accuracy with respect to nutrition knowledge were 90.3% and 77.0%, respectively, and the mean score of the nutrition knowledge was 17.5 on a basis of twenty-five. This indicates that the subjects had a comparatively deep concern for health and good knowledge of nutrition, and professed a relatively desirable attitude. These results indicate a desirable dietary attitude for children as well as parents. The correlation coefficients between nutrition knowledge and a concern for health, and between nutrition knowledge and nutritional attitude were very low. This suggests that the subjects' knowledge of nutrition does not develop into practice. The correlation coefficient was high (r=.610) between the concern for health and the nutritional attitude. In conclusion, the nutrition education program for mothers should be developed to add good practice to knowledge, thus increasing the concern for health, correcting their faulty knowledge of nutrition, teaching the good nutrition, and taking a practical attitude toward the use of their present nutritional knowledge.

Purpose: The purpose of this study was to identify the gender differences in the cognitive function and nutritional status among elderly people living in the community. Methods: This study used data from the 2014 National Survey on the Elderly and focused on 10,054 respondents who answered that they did not have dementia. The Korean version of Mini-Mental State Examination for Dementia Screening and the Nutrition Screening Initiative were used. IBM SPSS Statistics 23.0 was used to conduct statistical analyses. Results: The cognitive function score was 25.30 for men, which was higher than for women. The percentage of subjects who showed cognitive decline was 25.5% for males and 50.2% for females, which was statistically significant (p<.001). There were statistically significant differences in the nutritional status between males and females (p<.001). There was a statistically significant negative correlation between the cognitive function and nutritional status in both men and women (p<.001, p<.001). Conclusion: These results showed that the intervention to maintain cognitive functioning should be provided to elderly women with a low education level or high number of chronic diseases and medication, and an intervention to prevent the cognitive decline of the elderly should include nutritional management for health and function maintenance.

Purpose: This study addressed the relationship among nutritional risk, stress, and health related quality of life for older women with a foreign daughter-in-law. Methods: A descriptive research design was used for this study. The subjects of this study were 112 older women with a foreign daughter-in-law all of whom were over 65 years and living in D city. Personal interview was used for data collection. Nutritional risk, stress, and health related quality of life were measured using Nutrition Screening Initiative (NSI), Family Inventor of Life Events and Changes (FILE), and Medical Outcome Study (MOS) Short-form 36-Item Health Survey (SF-36), respectively. Results: Older women with a foreign daughter-in-law showed negative correlation between quality of life related health and nutritional risk, stress and age, and positive correlation between Activities of Daily Living (ADL); 46% of variance in health related quality of life of older women with a foreign daughter-in-law was explained by nutritional risk, ADL, stress and occupation. Conclusion: Based on the results of this study, we suggested that specialized programs should be established to help in development of social relationship networks for older women who have a foreign daughter-in-law.

Objectives: We aimed to examine health-related nutritional knowledge and dietary behavior related to caffeine intake among high school students (n = 310) in the Yongin region of Korea. Methods: Data were collected using a face-to-face survey, and analyzed using chi-square test, t- test, and logistic regression analysis. Results: The level of caffeine intake in respondents was divided into low (< 30 mg/d; n = 208) and high caffeine intake groups (> 30 mg/d; n = 102). Total nutritional knowledge related to bone disease was higher in the low intake group (score 2.75) than the high intake group (score 2.39; p < 0.05). The high intake group had lower scores for nutritional knowledge (score 0.70; p < 0.05) related to how caffeinated beverages affect sleep and for dietary behavior (score 3.25; p < 0.001), based on "I avoid caffeinated foods before sleep," than the low intake group (nutritional knowledge score, 0.80; dietary behavior score, 3.76). Conclusion: In the overall analysis, the low caffeine intake group had better nutritional knowledge related to bone and sleep health, and healthier dietary behavior related to sleep health compared with the high intake group.

This study was carried out to examine Korean housewives' preference in mushrooms, their nutritional knowledge of mushrooms as a source of Vitamin D, and five characteristics of four mushroom dishes. The data were collected from 713 subjects in various age ranges. The housewives ate mushrooms because of their healthfulness. Frequency of eating mushroom was related to preference of mushrooms. Frequency of eating mushroom was also influenced by intake of balanced diet, healthfulness of current diet, and application of nutritional knowledge. Mushroom dishes were considered nutritious (72.4%), easy to purchase (55.7%), easy to cook (63.7%) and expensive (36.3%). Mushroom was also considered superior to other vegetable in nutrition and taste but evaluated inferior to other vegetable in aspects of high price and limitation of variety. Intake of balanced diet, healthfulness of current diet and application of nutritional knowledge were influenced by the level of nutritional knowledge. Korean housewives liked mushroom but they didn't recognized the value of mushroom as a source of Vitamin D well. Introducing various cooking methods and nutritional informations are suggested to use mushroom diversely.
