Estimation of Usual Meat Intake Distribution Considering Meat Content in Processed Foods: Based on the KNHANES 2009 / 대한지역사회영양학회지

Objectives@#This study was conducted to estimate usual meat intake distribution, which may have been over/underestimated when estimations were made using only the third food codes of the Korea National Health and Nutrition Examination Survey (KNHANES). @*Methods@#For this purpose, 24-hour recall data from the 2009 Korea National Health and Nutrition Examination Survey, which conducted a partial 2-day survey of food intake, were used. The Multiple Source Method (MSM) was used to estimate the distribution of the usual intake of red and processed meats. @*Results@#The results of this study show that the mean intake of red meat was 45.07 g while that of processed meat was 4.33 g. These results are slightly higher than the consumption calculated using only tertiary food code, and the difference was statistically significant. Furthermore, characteristics of the estimated usual intake distribution were a smaller standard deviation, increased lower percentiles, and decreased upper percentiles compared to the 2- day mean intake distribution for both red and processed meats. The proportion of individuals not consuming red meat decreased substantially from approximately 37% to 0.7%. The proportion of consumption that exceeded 90 g, which is the upper limit of red meat intake recommended by the National Health Service (NHS), was only approximately 10% in the distribution of usual intake. @*Conclusions@#As the consumption of processed foods is expected to continuously increase, caution is needed regarding the processes used to calculate food (group) intake to avoid over/underestimation. Moreover, use of KNHANES data to calculate the proportion of the population at risk of insufficiency or excess intake of certain nutrients or food (group), based on one day intake that does not address within-individual variation, may lead to biased estimates.

Meta-Analysis of the Effects of Nutrition & Dietary Life Education for Preschoolers

The purpose of this study was to objectively quantify the effects of nutrition and dietary life education on preschoolers through meta-analysis. In addition, it provides basic data for the implementation of nutrition education and development of systematic nutrition and dietary life education programs. In this study, a meta-analysis of 27 papers was conducted that conformed to the selection criteria in the study conducted from January 2012 to August 2019 to derive objective data on the effects of education. As a result of the analysis, the overall effective size of nutrition and dietary life education for preschoolers was 0.829, which indicates a strong effect. According to the education method, the effect size of general education was 0.562, which indicates a medium effect size, the vegetable playing-based experience education was 0.685, which indicates a medium effect size, and cooking activity-based experience education was 1.101, which indicates a large effect size. Judging from this result, experience activity education was more effective than general nutrition education. In addition, the combined size of convergence education conducted through a combination of general and experience education was found to be the most effective at 1.301. In terms of educational effect, it was confirmed that the effect size was 0.898 for improving nutrition knowledge, 0.858 for improving dietary habits, 0.836 for improving unbalanced diet, and 0.756 for improving food preference and intake, and the sizes of effects were all found to be large. As frequency of education increased, the number of education participants decreased and the effect of education increased.

Quality Characteristics of Care Food (Jelly) Prepared with Wild Carrot (Daucus carota L.) Juice

This study evaluated the quality characteristics of jelly prepared with different levels (0%, 5%, 10%, 15%, 20%, and 25%) of wild carrot (WC, Daucus carota L.) juice as a care food for the elderly. The lightness, redness, yellowness, and delta (Δ) values of the jelly (Control, WCJ5, WCJ10, WCJ15, WCJ20, and WCJ25) decreased with increasing amounts of wild carrot juice added. The mechanical properties, such as hardness, springiness, chewiness, and gumminess, of the jelly were decreased with increasing amounts of wild carrot juice added. The total polyphenol and total flavonoid contents of the jelly increased with increasing amounts of wild carrot juice added. The DPPH radical scavenging activity (IC50) also increased with increasing amounts of wild carrot juice added. The α-glucosidase inhibitory effects of wild carrot (WC) and WCJ25 were 71% and 54.4%, respectively, compared to the positive control (acarbose). The lipase inhibitory effects of WC and WCJ25 were 44.2% and 14.4%, respectively, compared to the positive control group (orlistat). On the other hand, the sensory evaluation score was the best at WCJ20, which contained 20% wild carrot juice. In conclusion, WCJ20 or WCJ25 is expected to be a care food for the elderly with respect to texture as well as the antioxidant and enzymatic activity (α-glucosidase inhibitory and lipase inhibitory activities).

Genome-wide association study for the interaction between BMR and BMI in obese Korean women including overweight

BACKGROUND/OBJECTIVES: This is the first study to identify common genetic factors associated with the basal metabolic rate (BMR) and body mass index (BMI) in obese Korean women including overweight. This will be a basic study for future research of obese gene-BMR interaction. SUBJECTS/METHODS: The experimental design was 2 by 2 with variables of BMR and BMI. A genome-wide association study (GWAS) of single nucleotide polymorphisms (SNPs) was conducted in the overweight and obesity (BMI > 23 kg/m2) compared to the normality, and in women with low BMR (< 1426.3 kcal/day) compared to high BMR. A total of 140 SNPs reached formal genome-wide statistical significance in this study (P < 1 x 10(-4)). Surveys to estimate energy intake using 24-h recall method for three days and questionnaires for family history, a medical examination, and physical activities were conducted. RESULTS: We found that two NRG3 gene SNPs in the 10q23.1 chromosomal region were highly associated with BMR (rs10786764; P = 8.0 x 10(-7), rs1040675; 2.3 x 10(-6)) and BMI (rs10786764; P = 2.5 x 10(-5), rs10786764; 6.57 x 10(-5)). The other genes related to BMI (HSD52, TMA16, MARCH1, NRG1, NRXN3, and STK4) yielded P <10 x 10-4. Five new loci associated with BMR and BMI, including NRG3, OR8U8, BCL2L2-PABPN1, PABPN1, and SLC22A17 were identified in obese Korean women (P < 1 x 10(-4)). In the questionnaire investigation, significant differences were found in the number of starvation periods per week, family history of stomach cancer, coffee intake, and trial of weight control in each group. CONCLUSION: We discovered several common BMR- and BMI-related genes using GWAS. Although most of these newly established loci were not previously associated with obesity, they may provide new insights into body weight regulation. Our findings of five common genes associated with BMR and BMI in Koreans will serve as a reference for replication and validation of future studies on the metabolic rate.

Quality Characteristics of Yanggaeng Supplemented with Sanghwang Mushroom (Phellinus linteus) Mycelia

The principal objective of this study was to examine the quality characteristics of yanggaeng supplemented with powder derived from Sanghwang mushroom (Phellinus linteus) mycelia. We analyzed the potential of utilizing Phellinus linteus mycelia as a functional food material by estimating total polyphenol and flavonoid contents, electron-donating abilities, as well as antioxidative activities of the water and ethanol extracts of Sanghwang mushroom mycelia. The total phenol and flavonoid contents of ethanol extracts from Phellinus linteus mycelia were 0.69 mg/ml and 0.16 mg/ml, respectively, while the contents from the water extract of Phellinus linteus mycelia were 0.66 mg/ml and 0.22 mg/ml, respectively. The electron-donating abilities of ethanol and water extracts from Phellinus linteus mycelia were 88.64 and 90.29%, respectively. The ABTS radical scavenging activities of ethanol and water extracts from Phellinus linteus mycelia were 89.74 and 71.35%, respectively. In terms of color values, as the level of powder increased, the value of L (lightness) decreased, whereas those of a (redness) and b (yellowness) increased. In regard to the mechanical properties of the samples, we noted significant differences in hardness, springiness, chewiness, and gumminess (P<0.05). The results of the sensory evaluation showed that the score from SHM (Sanghwang mushroom mycelia) with 4% powder was significantly higher than other samples in terms of sweetness, color, taste, texture and overall quality (P<0.05). Taken together, the recommended level of Phellinus linteus mycelia powder in yanggaeng is 4% for optimal sensory characteristics.

An average age of the female marriage immigrants who participated in this survey were 28.6 years, and their home countries were the Philippines (32.6%), Vietnam (29.1%), and so on. Exactly 59.3% of subjects had been married for 1~5 years, and 40.7% of the subjects had an education status of less than middle school graduation. The majority of them (65.1%) had one more children, and 51.2% of subjects were a part of a nuclear-family, with the husband's age between 40~49 years old (58.1%). Concern for nutrition label was significantly different according to number of children (P10 years than <1 year (P<0.01), and education level of college & university graduation than less than middle school (P<0.05). Sixty percent of the women surveyed participated in the education program of 'Korean language' as they were in their country, and the most preferred education program was 'Korean dietary life and culture' (39.5%). Regarding participation and educational method, the majority of subjects responded that they wanted to learn nutritional education in a cooking academy or school (52.9%) and public health center (34.1%).

Quality Characteristics of Mungbeanmook Added with Gugija (Lycii fructus) Infusion

The principal objective of this study was to evaluate the quality characteristics of mungbeanmook prepared with five different levels (0, 5, 10, 15, and 20%) of Gugija (Lycii fructus) infusion. We analyzed Hunter's color values, pH, texture characteristics, and perfomed sensory evaluation of mungbeanmook prepared with Gugija infusion. The pH levels of mungbeanmook ranged between 5.45 and 6.12 and did not show significant differences. As Gugija infusion concentration increased, the color lightness "L" value decreased, whereas redness color "a" value and yellowness color "b" values increased (P<0.05). With regard to mechanical texture properties of the mungbeanmook samples, as the Gugija infusion concentration increased, the scores of hardness, chewiness, and gumminess all significantly decreased (P<0.05) whereas there were no significant differences in springiness or cohesiveness. The results of the sensory evaluation showed that the score of the LFLT10 sample (10% Gugija infusion) was significantly higher than those of others in terms of taste, color, flavor, texture, and overall quality (P<0.05). Taken together, the recommended optimum level of Gugija infusion in mungbeanmook is 10% for sensory evaluation. Gugija infusion can be a useful approach to improving quality of mungbeenmook as a functional food.

Also, all subcategories in Yangsaeng were positively related to all domain of quality of life. CONCLUSION: The results indicate that the quality of life of adult and elderly Koreans who practice DJB is more closely associated with Yangsaeng. Therefore, Dan Jeon Breathing can be utilized as a nursing intervention for Yangsaeng and quality of life of Koreans.

Hypoglycemic effect of Rehmannie Radix Preparata (Sookjihwang) extract in streptozotocin-induced diabetic rats

Rhemannie Radix Preparata (RRP) has been previously employed in traditional oriental medicine as a treatment for diabetic thirst and improving blood flow. The aim of this study was to evaluate its hypoglycemic control by assaying the activities of key enzymes of carbohydrate metabolism in streptozotocin-(STZ)-induced diabetic rats. Further, RRP extracts were prepared in water (RRPW), in 50% ethanol (RRP50), and in 100% ethanol (RRP100), respectively, and compared for their actions in diabetic rats. The oral treatment of RRP (5 mg/kg b.w./d) to diabetic rats for 21 days resulted in a significant decline in blood glucose by 67% compared to diabetic control rats (P < 0.05). The altered activities of glucokinase, glucose-6-phosphate dehydrogenase (G6PD), 6-phosphogluconate dehydrogenase (6PGD), and acetyl CoA carboxylase (ACC) in the livers of diabetic rats were reversed significantly to near-normal levels by the administration of RRP (P < 0.05). Among the three RRP extracts, RRP100 was the most effective in terms of hypoglycemic action. However, the administration of RRP to diabetic rats did not improve insulin production. The modulatory effects of RRP100 on the attenuation of carbohydrate enzyme activities appear to hold promise for widespread use for the treatment of diabetes in the future.

Adaptation to Menopause and Use of Yangsaeng in Middle-aged Korean Women / 여성건강간호학회지

PURPOSE: The study addressed the adaption of middle-aged Korean women to menopause, including the use of Yangsaeng, a traditional health care regimen that incorporates specific principles and methods to promote health and prevent illness, with the aim of improving health and longevity of life. METHODS: Middle-aged women (40~59 years, n=171) residing in Seoul and Gyeong-Gi Province. Data was collected by using a self-reported questionnaire. Menopausal period adaptation was measured by 29 items in four categories (physical, self-concept, role function, and inter-dependent). Yangsaeng was measured by 31 questionnaire items in eight categories (morality, mind, diet, activity and rest, exercise, sleep, seasonal, and sexuality). RESULTS: Significant differences in menopausal adaptation were evident on the basis of participant education and income. There were significant differences in Yangsaeng in terms of participant education, nature of employment, and income. Menopausal adaptation positively correlated to use of Yangsaeng. Physical adaptation, self-concept adaptation, role function adaptation, and inter-dependent adaptation positively correlated to morality Yangsaeng, mind Yangsaeng, and activity and rest Yangsaeng. CONCLUSION: Middle-aged Korean women who practice Yangsaeng may be better positioned to adapt to menopause. Yangsaeng may be an advantageous nursing intervention in this population.

The antioxidant and chemopreventive potentialities of Mosidae (Adenophora remotiflora) leaves

Our study focused on the antioxidant activities of Mosidae leaf ethanol extract (MLE) and included measurements of reducing power, total phenolic compounds, DPPH radical scavenging activity, and hydroxyl radical scavenging activity. In order to determine whether or not MLE evidences any chemopreventive activities, experimental lung metastasis was induced via the i.v. inoculation of colon26-M3.1 carcinoma cells into BALB/c mice. Additionally, we attempted to characterize any possible cytotoxic effects in murine normal splenocytes and tumor cells (B16-BL6 and colon26-M3.1). The total phenolic content and reducing capacity were measured at 39 mg/100 mL and 1.24, respectively, whereas the DPPH and hydroxyl radical scavenging activities of MLE were measured to be 88.89% and 22.10%, respectively. Prophylactic i.v. treatment with MLE resulted in a dose-dependent and significant inhibition of lung metastasis. Specifically, a MLE dose of 200 ug per mouse resulted in an 88.90% inhibition of lung metastasis. For the cytotoxicity assay, MLE doses up to 100 ug/mL were not shown to affect the growth of normal murine splenocytes. Additionally, the survival of normal cells was not affected at MLE doses below 500 ug/mL. However, MLE doses up to 500 ug/mL reduced the percentage of tumor cell growth for B16BL6 (67% alive) and colon26-M3.1 (62% alive) cells.

Stress, Depression and Health Risk Behaviors in Korean Elders

PURPOSE: The purpose of this study was to investigate stress, depression and health risk behaviors in elderly people. METHODS: The subjects were 238 Korean elders who had visited the convalescent center. The level of stress was measured by the Korean version of BEPSI, which was developed by Bae, Jeung & Yoo (1992) and modified by Yim et al.(1996). CES-D was used to measure the level of depression. For health risk behaviors, we measured cigarette consumption and alcohol drinking during the last one month. RESULTS: Of the subjects, 17.4% were excessive drinkers and 18.9% were currently smokers. The level of stress was between moderate and high, and 62.7% of the subjects were depressed. There were significant differences in stress and depression according to economic status and self-reported health. In addition, depression had positive correlations with stress and QF score. CONCLUSION: Stress and depression management programs for the elderly are needed. These findings indicate that nurses must consider stress and alcohol drinking when they take care of depressed elderly people.

The Relationship between Health Risk Appraisal and Health-related Quality of Life among Middle-aged Men

BACKGROUND: Recently, several health risk appraisal programs have been developed to suit Korean character which is currently implemented. This study was conducted to find out the correlation with health age and health-related quality of life through health risk appraisal. METHODS: From March 1, 2004 to July 30, 2004, 107 male patients aged 30 to 59 who visited the family medicine clinic in a university hospital and had agreed to participate in the study have been assessed to determine the correlation between health age and health-related quality of life by measuring tools of health risk appraisal, CMCHS V1.0 questionnaire and Yangseng measurement questionnaire. RESULTS: Among the total 107 subjects, 3 were excluded because of incomplete questionnaire. There were 28 people aged in their thirties, 36 in forties, and 40 in fifties. The health age and health-related quality of life showed a negative correlation. The correlation in men in their fift showed the strongest. Indexes between the health age and health perception, changes in health, vitality, morality Yangseng, diet Yangseng, sleep Yangseng and active and rest Yangseng have shown a strong negative correlation (P<0.05). CONCLUSION: The lower the health age is, the better health-related quality of life in several domains of CMCHS V1.0 and Yangseng in middle aged Korean men.

Effects of Mulberry Leaf Powder Supplementation on Lead Status and Minerals content in Pb-administered Rats

This study was designed to investigate the effects of mulberry leaf powder supplementation on lead (Pb) status and mineral (Ca, Fe, Cu and Zn) content in Pb-administered rats for 4 weeks. Thirty two male rats were divided into 4 groups: a control, Pb, Pb5M (500 ppm Pb + 5% mulberry leaf powder), and Pb10M (500 ppm Pb + 10% mulberry leaf powder). There were no significant differences in food intake and initial body weight among groups. Mulberry leaf powder treatments showed significant decreases in food efficiency ratio and body weight gain. But FER of Pb5M% and Pb10M were significantly increases than that of Pb group. The levels of serum aspartate transaminase (AST) and creatinine were decreased by mulberry leaf powder treatment. Minerals content of liver and kidney were significantly decreased in the Pb groups than that of control group. Whereas, fecal minerals content were significantly increased in the Pb5M and Pb10M than those of control group. Pb content of serum, liver and kidney was significantly increased in the Pb group than those of control group. However, by mulberry leaf powder administration (Pb5M and Pb10M), Pb level of serum, liver and kidney were lowered than that of Pb group. And fecal Pb excretion was significantly increased in the Pb5M and Pb10M than that of Pb group. These results showed mulberry leaves were effective for lowing Pb accumulation in serum, organs, which may have potential to prevent Pb toxicity.

A Retrospective Study on the Status of Obesity and Eating and Weight Control Behaviors of Elementary School Children in Inchon

Two hundred sixty six children were retrospectively surveyed from first to fifth grade to find out the status of obesity during four years. The obesity index was gained by height and weight data from student's health file and the data about eating behaviors and weight control behaviors, etc. were collected by questionnaires. Children assigned to one of the following groups : underweight, normal, overweight and obese. The results were as follows ; 1. Obese children were 18.6%(n=27) of boys and 10.8%(n=13) of girls at fifth grade. 2. Twenty eight children among forty obese children at fifth grade were also overweight or obese at first grade, and the other twelve was normal. 3. Breakfast skipping rate was significantly high among underweight and obese group of boys(p<0.01).The most children(8736%) had prejudice for special foods. 4. The rate of agreement between obesity index and self recognition of body image was 60.7% in boys and 63.6% in girls. 5. Forty two point five percent of children have ever tried weight control as exercise(35.7%), reducing sugars and snacks(27%), feasting(23.8S%), avoiding fatty foods(12.7%), taking diet food or drug(0.8%). In conclusion, the prevalence of children obesity is gradually increasing and children tried weight control without right guidances. In order to prevent progress into adulthood obesity, nutrition education should be followed with school foodservice including the right perception for obesity, proper weight control and eating behavior modification.

A Study on Nutritional Attitude, Food Behavior and Nutritional Status according to Nutrition Knowledge of Korean Middle School Students / 대한지역사회영양학회지

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/m2, 157.0 cm, 50.4 kg, and 20.4 kg/m2 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 B1, vitamin B2, niacin, vitamin C, fat, and animal protein intakes in females are shown to be related to their nutrition knowledge. Calcium, protein, animal protein, vitamin B2 and niacin intakes are significantly lower in the VLG than in the others. However, vitamin B1 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.
