1.Socio-economic status is associated with the risk of inadequate energy intake among Korean elderly.
Journal of Nutrition and Health 2015;48(4):371-379
PURPOSE: This study was conducted to evaluate the factors influencing inadequate energy intake among Korean elderly. METHODS: Our study included 1,869 elderly people (over 60 years old) who completed a dietary survey from the fifth Korean NHANES (2010). Factors that could affect the nutritional status of the elderly included age, family status, socio-economic factors (education, family income, livelihood security, employment), and health related factors (having chronic disease, functional status, diet therapy, depression, and suicidal thoughts). Energy and protein intake were assessed using the dietary intake data from 24hr recall method. RESULTS: The percentage of people who consumed energy less than 75% of EEA for Koreans was 23.7% in men, 31.1% in women. The carbohydrate contribution to the total energy intake in the inadequate energy intake group was significantly higher than that in the adequate intake group (p < 0.05). Factors significantly related to inadequate energy intake after adjusting for age, family status, education, family income, employment, functional status, and suicidal thoughts were education (OR: 1.480 in men, 1.614 in women) and employment (OR: 1.751 in men, 1.464 in women), age 70 years or older in men (OR: 1.475), and living with family but without spouse in women (OR: 1.496). CONCLUSION: In summary, the results imply that energy intake of elderly would be affected by the status of social environment with aging and nutrition-related policy for Korean elderly should be based on the social status as well as health related conditions.

Journal of Nutrition and Health 2015;48(4):364-370
PURPOSE: This study was conducted to evaluate nutritional status in middle-class adults compared with low income or high income adults according to gender difference. METHODS: Data from the 2012 Korea National Health and Nutrition Examination Survey was used. A total of 7,082 adults aged from 30 to 64 were included and classified according to household income level into three groups. Dietary data was collected using 24-hr recall methods. RESULTS: Most nutrients including energy, protein, vitamins, and minerals such as iron and calcium differed according to income levels. Iron intake of middle-class men was higher than that of the lowest income group, whereas that of middle-class women was similar to that of the lowest income group. In addition, no significant difference in carbohydrate, protein, fat, thiamin, and niacin intakes per 1,000 kcal and iron intake was found between the middle and high income group only in male subjects. In summary, our results showed that the relationship between nutritional status and income level as a socioeconomic parameter could vary according to gender difference. CONCLUSION: According to our results, it could be suggested that not only the lowest income people but also middle class women should be concerned in development of nutritional policies. Gender difference should be considered. It is a very meaningful implication for application to policy for obesity prevention or intervention.

3.Use of vitamin and mineral supplements and related variables among university students in Seoul.
Journal of Nutrition and Health 2015;48(4):352-363
PURPOSE: Despite the popularity of dietary supplements, little data are available on their use by university students. The purpose of this study was to examine the use of vitamin mineral supplements and to identify factors related to supplement use among university students. METHODS: University students (N = 345) in Seoul were surveyed. Survey questions included descriptive demographics, types of vitamin and mineral supplements used, health related lifestyle factors, mini dietary assessment, and knowledge and behaviors related to supplement use. RESULTS: Of university students surveyed, 41% consumed vitamin and mineral supplements. Among the supplement users, multivitamins were the most commonly used dietary supplements (68.6%), followed by vitamin C (31.4%) and calcium (17.1%). In particular, the use of vitamin C and iron supplements was more common in females than males (p < 0.05). For the number of supplements taken daily, 32.1% of supplement users consumed 2 or more supplements; 20% of supplement users had almost no knowledge of the supplements being taken. Based on the results of multivariable logistic regression analysis, supplement use was associated with higher interest in their own health, non-smoker, and supplement use by family (p < 0.05). In addition, supplement use was slightly associated with healthy dietary behavior such as consuming a variety of foods (p = 0.05) and current disease status (p = 0.05). CONCLUSION: University students with relatively healthy lifestyles appear to take vitamin and mineral supplements, but they had little knowledge of the supplements. Given high prevalence of dietary supplement use among university students, nutrition education regarding supplement use is needed.

Journal of Nutrition and Health 2015;48(4):344-351
PURPOSE: During the recent decades, the age at menarche continued to decline in Korea and worldwide. Prior studies have suggested that early menarche may increase the risk of various social, psychological, and physical health problems in young adolescent girls, but little is known about the determinants associated with early menarche. The purpose of this study is to evaluate independent determinants of early menarche among 5th~6th female graders in South Korea. METHODS: Our analysis was conducted in 95 menarcheal girls and 95 age-matched pre-menarcheal girls residing in Daegu, South Korea. Demographic and lifestyle characteristics were collected using survey questionnaires for children and parents. Dietary information was assessed by 2 day~24 hour food records and survey questionnaires, which were completed by both children and their parents. Anthropometric data were obtained from the student health check-ups at the school. RESULTS: A multiple logistic regression analysis using a conditional likelihood method was performed for simultaneous evaluation of several risk factors. There were significant differences in that higher proportion of obesity (OR, odds ratio = 5.60, 95% CI, confidence interval = 1.34~23.42), shorter sleep duration (OR = 0.45, 95% CI = 0.23~0.87), and younger mother's age at menarche (OR = 0.64, 95% CI = 0.44~0.93) were observed in the menarcheal group compared to the premenarcheal group. CONCLUSION: These findings indicate a possible association of sleep duration, mother's menarcheal age, and obesity with age at menarche. A well-planned, prospective cohort study is warranted to examine causal relationship.

Journal of Nutrition and Health 2015;48(4):335-343
PURPOSE: The aim of this study was to evaluate the food behavior and nutritional status of elementary school students in the Jeju area using Nutrition Quotient (NQ). METHODS: The subjects were 440 students (235 boys and 205 girls) in the fifth and sixth grade at four elementary schools located in Jeju. Demographic, lifestyle, and environmental information was collected using a self-reported questionnaire. The food behavior checklist for children's Nutrition Quotient (NQ), consisting of 19 items, and nutrition education related information were also obtained. RESULTS: The mean score of the children's NQ was poor, reaching 60.3 points. The percentage distribution of NQ grade was 19.8% (lowest), 18.6% (low), 45.0% (medium), 10.7% (high), and 5.9% (highest) and the factor scores for balance, diversity, abstinence, regularity, and practice were 56.6, 68.4, 71.3, 57.4, and 54.8 points, respectively. Compared with the NQ cut-off points for defining malnutrition (balance; 57, diversity; 87, abstinence; 66, regularity; 69, and practice; 67 point), average score of abstinence factor was only above the cut-off point and scores of the other factors were below the cut-off point. Subjects with higher NQ scores tended to have higher levels of exercise activity (p < 0.001), frequency of family meals (p < 0.01), and father's educational levels (p < 0.01) compared to those with lower NQ score. NQ score showed positive association with nutrition education experience and practice (p < 0.001) CONCLUSION: NQ score of elementary school students residing in Jeju was lower than the national average. More opportunities should be provided for participation in nutrition education, which incorporates a range of program strategies, as well as communication and education activities.

6.Effects of (6)-gingerol, ginger component on adipocyte development and differentiation in 3T3-L1.
Journal of Nutrition and Health 2015;48(4):327-334
PURPOSE: The objective of this study was to investigate the effects of (6)-gingerol, ginger components proliferation and adipocyte differentiation from early to lately steps. METHODS: 3T3-L1 preadipocytes were cultured. Differentiation of confluent cells was induced with dexamethasone, isobutylxanthin and insulin for 2 day and cells were cultured by medium with insulin in presence of various concentrations 0, 25, 50, 100 (micromol/L) of (6)-gingerol for 4 day. Cell viability was measured using the EZ Cytox assay kit. In addition, we examined the expression of mRNA levels associated with each adipocyte differentiation step by real time reverse transcription polymerase chain reaction. RESULTS: (6)-Gingerol inhibited adipocyte proliferation in a dose and time dependent manner. Expression of C/EBPbeta, associated with early differentiation step remained unchaged. However, intermmediate, late differentiation step and adipocytokines were effectively changed in dose-dependently manner in cell groups treated with (6)-gingerol. CONCLUSION: This study has shown that treatment with (6)-gingerol inhibited adipocyte proliferation as well as each adipocyte differentiation step. In particular, the (6)-gingerol more effectively inhibited adipocyte differentiation from intermmediate differentiation step.

7.Comparative effect of dietary borage oil and safflower oil on anti-proliferation and ceramide metabolism in the epidermis of essential fatty acid deficient guinea pigs.
Journal of Nutrition and Health 2015;48(4):319-326
PURPOSE: Borage oil (BO) and safflower oil (SO) are efficacious in reversing epidermal hyperproliferation, which is caused by the disruption of epidermal barrier. In this study, we compared the antiproliferative effect of dietary BO and SO. Altered metabolism of ceramide (Cer), the major lipid of epidermal barrier, was further determined by measurement of epidermal levels of individual Cer, glucosylceramide (GlcCer), and sphingomyelin (SM) species, and protein expression of Cer metabolizing enzymes. METHODS: Epidermal hyperproliferation was induced in guinea pigs by a hydrogenated coconut diet (HCO) for 8 weeks. Subsequently, animals were fed diets of either BO (group HCO + BO) or SO (group HCO + SO) for 2 weeks. As controls, animals were fed BO (group BO) or HCO (group HCO) diets for 10 weeks. RESULTS: Epidermal hyperproliferation was reversed in groups HCO + BO (67.6% of group HCO) and HCO + SO (84.5% of group HCO). Epidermal levels of Cer1/2, GlcCer-A/B, and beta-glucocerebrosidase (GCase), an enzyme of GlcCer hydrolysis for Cer generation, were higher in group HCO + BO than in group HCO, and increased to levels similar to those of group BO. In addition, epidermal levels of SM1, serine palmitoyltransferase (SPT), and acidic sphingomyelinase (aSMase), enzymes of de novo Cer synthesis and SM hydrolysis for Cer generation, but not of Cer3-7, were higher in group HCO + BO than in group HCO. Despite an increase of SPT and aSMase in group HCO + SO to levels higher than in group HCO, epidermal levels of Cer1-7, GlcCer-A/B, and GCase were similar in these two groups. Notably, acidic ceramidase, an enzyme of Cer degradation, was highly expressed in group HCO + SO. Epidermal levels of GlcCer-C/D and SM-2/3 did not differ among groups. CONCLUSION: Dietary BO was more prominent for reversing epidermal hyperproliferation by enhancing Cer metabolism with increased levels of Cer1/2, GlcCer-A/B, and SM1 species, and of GCase proteins.

Journal of Nutrition and Health 2017;50(6):664-678
PURPOSE: To identify the effectiveness of policy evaluation, consistent monitoring is necessary. This study aimed to carry out mid-term evaluation of objectives and programs related to comprehensive plans for sodium intake reduction by 2020 for Seoul city and then reestablish the objectives of the sodium intake reduction plans. METHODS: Literature reviews, data analysis, and reviews of expert focus-groups were performed to evaluate objectives, to develop a new goal, and to identify the priority subjects of the sodium intake reduction programs. In order to examine target populations for the programs, awareness and behaviors related to sodium intakes among Seoul citizens were examined by sex, age, and income level using the 2008~2013 Korea National Health and Nutrition Examination Survey data. RESULTS: Current objectives of the sodium intake reduction plan by 2020 for Seoul city were not appropriate, so objectives were reset to 3,600 mg of sodium intake by 2020 among Seoul citizens with 2% reduction per year. Although sodium intake showed a decreasing trend by year, it was still high, especially in men. The sodium intake reduction programs currently in progress have not been assessed at multiple levels across multiple sectors and have only been assessed fragmentarily. For dietary behavior related to sodium intakes by sex, age, and income level, sodium intake was higher in the group with less than 100 g of fruit intake compared to the group with 100 g or more. Subjects aged 30~59 years and the low household income group showed relatively higher sodium intakes. Based on the data analysis and the expert review, the priority subject of the sodium intake reduction programs was determined to be adult men. In terms of a program strategy for sodium intake reduction, multi-level and setting approaches, including work sites, home, and restaurants, were suggested to reduce sodium intakes of the target subject. CONCLUSION: The suggested objectives should be consistently monitored by data analysis, and the determined programs need to be phased in over 5 years.

9.Analysis of sodium content of representative Korean foods high in sodium from home meal, foodservice, and restaurants.
Journal of Nutrition and Health 2017;50(6):655-663
PURPOSE: The aim of this study was to analyze the sodium contents of representative Korean foods high in sodium and develop them as a fundamental resource for setting the standard amount of sodium in foods. METHODS: A total of 480 representative Korean foods high in sodium were collected from households, foodservice establishments, and restaurants in four regions (Capital region, Chungcheong & Gangwon Province, Gyeongsang province, and Jeolla province) and analyzed their sodium content. RESULTS: The sodium content (per 100 g) of food categorized by food group was highest in kimchi and braised food (p < 0.001), and the sodium content of each food was highest in stir-fried anchovies (1,896.6 mg) followed by braised burdock and lotus roots (820.6 mg) and picked onions (809.3 mg) (p < 0.001). However, the sodium content per portion of food was highest in steamed short ribs (1,429.6 mg) from home meals (p < 0.001), Bibimbap, (1,074.1 mg) and steamed short ribs (838.8 mg) from foodservice (p < 0.001), spicy beef soup (3,273.2 mg), and pollack stew (2,930.2 mg) from restaurants (p < 0.001). The sodium content per 100 g and portion of soups and stews from restaurants was significantly higher than that of home meals and foodservice meals (p < 0.001), and the sodium content per portion of steam dishes and stir-fried dishes from home meals was significantly higher than that of foodservice meals (p < 0.05). CONCLUSION: These results suggest that developing and using low-sodium soybean sauces & soybean paste and kimchi is needed in an effort to reduce sodium intake. In addition, determination of the sodium contents of representative Korean foods known to be high in sodium is expected to be useful in establishing guidelines for reduction of sodium content.
