The present study was conducted to document the association between plasma homocysteine levels and the presence of macrovascular angiopathy with food and nutrient intake patterns among patients with Type II diabetes mellitus in Korea. Plasma total homocysteine concentration was analyzed by HPLC-fluorescence detector method in 127 patients with non-insulin dependent diabetes mellitus. Logistic regression analyses were performed respectively to study the association of plasma homocysteine levels with clinical and dietary characteristics and macroangiopathy (MA). The average plasma homocysteine level of patients with MA was $14.2{\mu}mol/l$, which was significantly higher than that of patients without MA ($11.4{\mu}mol/l$). The proportions of patients with MA showed a significant difference, being 32.3% in hyperhomocysteinemic ($>14.0{\mu}mol/l$) patients and 13.5% in others with homocysteine levels lower than $14.0{\mu}mol/l$. Odds ratios for macroangiopathy by tertile increase of plasma homocysteine concentration were 1.633 ($Q_2$) and 4.831 ($Q_3$), when adjusted for age, sex, and cigarette smoking. Patients with MA consumed reduced amounts of vitamin $B_1,\;B_2$, and folate. The results indicate that the plasma homocysteine levels are significantly increased in NIDDM patients who have macroangiopathy. Dietary management such as increased fruits and vegetables and decreased potatoes and starches might be beneficial for the prevention of macroangiopathy in diabetic patients.
BACKGROUND/OBJECTIVES: Hypertension is the major risk factor for cardiovascular disease, a leading cause of deaths in Korea. The objective of this study was to evaluate the effect of a nutrition education in reducing sodium intake and increasing potassium intake in hypertensive adults. SUBJECTS/METHODS: Subjects who participated in this study were 88 adults (28 males and 60 females) who were pre-hypertension or untreated hypertensive patients aged ≥ 30 yrs in Gyeonggi Province, Korea. These subjects were divided into 2 groups: a lowsodium education (LS) group and a low-sodium high-potassium education (LSHP) group. Nutrition education of 3 sessions for 12 weeks was conducted. Blood pressure, blood and urine components, nutrient intake, and dietary behavior were compared between the two education groups. RESULT: Blood pressure was decreased in both groups after the nutrition education (P < 0.05). In the LSHP group, levels of blood glucose (P < 0.05), total cholesterol (P < 0.01), and lowdensity lipoprotein-cholesterol (P < 0.05) were decreased after the program completion. Sodium intake was decreased in both groups after the nutrition education (P < 0.05). However, Na/K ratio was only decreased in the LS group (P < 0.05). Intake frequency of fish & shellfish was only significantly reduced in the LS group (P < 0.05), while intake frequencies of cooked rice, noodles & dumplings, breads & snacks, stew, kimchi, and fish & shellfish were reduced in the LSHP group (P < 0.05). Total score of dietary behavior appeared to be effectively decreased in both groups after the education program (P < 0.001). CONCLUSIONS: This education for reducing sodium intake was effective in reducing blood pressure and sodium intake. The education for enhancing potassium intake resulted in positive changes in blood glucose and serum cholesterol levels.
BACKGROUND/OBJECTIVES: The objective of this study was to determine dysphagia risk among community-dwelling elderly people living at home. We also examined the impact of socio-demographic variables on dysphagia risk as well as the relationship between dysphagia risk and dietary characteristics. SUBJECTS/METHODS: The study sample included 568 community-dwelling individuals, aged 65 years and above, who were living independently in their own home in Seoul, Gyeonggi, or Gwangju in South Korea. We used a dysphagia risk assessment scale to screen for dysphagia risk and the Mini nutritional assessment to evaluate the nutritional status. Associations between dysphagia risk and other variables were assessed using logistic regression analysis. RESULTS: Of the 568 subjects, 350 (61.6%) were classified into the dysphagia risk group (DR) and 218 (38.4%) were classified into the normal group (non-DR). Being female (odds ratio (OR) = 1.82, 95% confidence interval (CI) = 1.28-2.59), being 75 years and older (OR = 2.40, 95% CI = 1.69-3.42), having a lower education level (OR = 2.29, 95% CI = 1.33-3.97), and having a lower perceived economic status (OR = 2.18, 95% CI = 1.32-3.60) were more frequently observed with dysphagia risk compared to those who did not have such characteristics. Lowered mastication ability (OR = 14.40, 95% CI = 4.43-46.95), being at risk of malnutrition or malnourished (OR = 2.72, 95% CI = 1.75-4.23), lowered appetite (OR = 3.27, 95% CI = 2.16-4.93), and decreased food intake (OR = 2.95, 95% CI = 1.83-4.78) were observed more frequently in the DR group than in the non-DR group when adjusting for potential confounding factors. CONCLUSIONS: It is necessary to develop and apply integrated programs to improve the dietary habits and nutritional status of elderly individuals at risk for dysphagia, especially for women aged 75 years or older with lower educational and economic levels.
BACKGROUND/OBJECTIVES: As watching food-related programs has become very popular among the young generation in Korea, this study sought to compare the Mukbang- and Cookbang-watching status of university students with their dietary life. SUBJECTS/METHODS: The participants were 380 students who were not majoring in food and nutrition at a university in Gyeonggi, Korea. Based on self- reports, the participants were grouped according to their frequency of watching Mukbang or Cookbang: frequent-watching (FW) 21.1% and 5.3%, respectively; moderate-watching (MW) 43.9% and 27.9%, respectively; and not-watching (NW) 35.0% and 66.8% respectively. RESULTS: In the FW group, up to 88.8% and 70.0% of participants reported watching Mukbang and Cookbang, respectively, ≥ 3 days/week. Almost all participants in the FW and MW groups reported intention to keep watching these shows. The most frequent watching route was "YouTube" and the most important criterion to select a program was "food". In the case of Mukbang, but not Cookbang, the participants in the FW group scored their diet significantly worse than those in the NW group (P < 0.05). A greater proportion of participants felt that watching Cookbang improved their diets rather than worsened them (14.3% vs. 0.8%, respectively), while more participants said that watching Mukbang worsened their diets rather than improved them (8.1% vs. 2.4%, respectively). In both cases, greater differences were shown in the FW groups compared to the MW groups (P < 0.05 and P < 0.01 for Cookbang and Mukbang, respectively). Moreover, the participants answered that Mukbang-watching prompted them to eat more of less desirable food, such as through eating out and purchasing convenient and delivered foods, whereas Cookbang-watching made them want to cook more of their own food. CONCLUSIONS: Our results suggested that Korean university students who frequently watch Mukbang, but not Cookbang, may be a nutritionally vulnerable group that needs attention.
Regional differences between large cities and rural areas are observed in the Korean National Health and Nutrition Examination Survey (KNHANES). This present study was conducted to evaluate the effect of dietary factors on hypertension risk in Korean populations, especially residents of the Chungcheong province which was not in metropolitan area, using KNHANES III. A total of 544 adults aged ${\geq}$ 19 years were placed into either the normotensive or the hypertensive group. Subject characteristics, BMI, blood pressure, and nutrient intakes were compared between the two groups using a chi-square test and t-test. We estimated odds ratios (ORs) using multiple logistic regression, adjusted for energy intake and selected covariates. There were significant differences in age, education level, alcohol consumption, and BMI between the normotensive and hypertensive groups. We found decreased ORs for the medium versus lowest tertile of calcium intake (multivariate OR=0.43, 95% CI: 0.21-0.88), for the highest versus lowest tertile of calcium intake (multivariate OR=0.43, 95% CI: 0.20-0.90) with significant trends in risk (P=0.040), and for the medium versus lowest tertile of potassium intake (multivariate OR=0.43, 95% CI: 0.20-0.89). Subjects with the highest sodium/calcium ratio had a 2.10-fold greater risk of hypertension compared to the subject with the lowest, with significant trends in risk (P=0.002). Adequate calcium and potassium intake should be encouraged and regional differences should be considered in making a healthy plan for hypertension management.
This study investigated the nutrition education realities and nutrition status of children in community child centers, by analyzing the status of nutrition education, nutrition quotient (NQ), and the level of maintaining dietary guidelines. The subjects were 173 children from grades 1 to 6, enrolled in community child centers, Jinju, Kyungnam. The NQ was examined by a questionnaire, which was a checklist of 19 food behavior items. The distribution of scores (out of 100) in the nutrition quotient were as follows: total score of NQ was 59.4, balance 56.6, diversity 60.6, moderation 65.6, regularity 60.9, and practice 56.7. Nutrition quotient was higher in the higher graders due to significant differences in the area of variety. The level of maintaining dietary guidelines was higher in girls, especially in the area 'eat politely with family', and higher amongst the upper graders in the area 'have safe snack wisely'. To improve the eating habits and nutritional status of the children in community child centers, their nutritional state should be checked with regular and systematic education, and their nutritional management should be pursued continuously. Since the assessment of the eating behaviors and the nutritional state of children is important at home as well as in schools and community child centers, nutritional education should be further extended to the parents and their care givers. This study can be implemented as basic material for the nutritional education of children, to minimize the dangers of malnutrition and to help build up the right eating habits amongst children in community child centers.
This study aimed to compare and evaluate nutritive conditions of the female elderly (2,893 people) based on a national health nutrition survey and health-related factors influencing nutritional intake. The results are as follows.- Average age of all subjects was $72.12{\pm}5.2$ old. BMI ($24.48{\pm}3.3kg/m^2$) and waist size ($83.9{\pm}9.5cm$) of urban elderly was larger ($23.74{\pm}3.3kg/m^2$, $82.28{\pm}9.9cm$) than that of rural elderly. MAR[4] and MAR[10] were also higher in urban elderly than rural elderly. The results of multiple regression analysis showed that factors influencing poor nutrition of elderly subjects were increasing age, smoking, and self-rated health. Old-old and current smokers were associated with a higher likelihood of poor nutrition (OR 1.82, 95%CI 1.43~2.30) and (OR 3.40, 95%CI 2.17~5.33) elderly female subjects in urban areas. Smoking (OR 2.29, 95%CI 1.33~3.95), poor self-rated health (OR 1.55, 95%CI 1.11~2.16), over nine hours of sleep per nighting (OR 1.72, 95%CI 1.17~2.53) and stress (OR 1.46, 95%CI 1.10~1.92) of elderly female subjects in rural areas were associated with higher likelihood of a poor nutrition. In conclusion, rural elderly are more influenced by poor health practice behaviors (self-rated health, sleeping stress) and psychological factors. Nutrition status of the rural elderly is worse than that of the urban elderly. To reduce nutritional risk of Korean elderly, especially rural elderly, active nutrition arbitration should include psychological environmental factors.

This experiment was conducted to evaluate the long term effects of dehulled soybean meal (DHSM) as fish meal (FM) replacer in the diet for olive flounder, Paralichthys olivaceus, for 42 wk at a commercial fish farm. The four experimental diets were MP (moist pellet based on raw fish), $DHSM_0$ (fish meal based dry pellet), $DHSM_{30}$ (30% fish meal was replaced by DHSM) and COMD (commercial dry pellet). Fish were fed one of the four diets containing 50% crude protein and 16.7 kJ available energy/kg diet for 42 wk. Fish averaging $3.20{\pm}0.04g$ ($mean{\pm}SD$) were initially distributed to each tank as a group of 6,000 fish reared in a flow-through system. At the end of the experiment, average body weight of fish was $315{\pm}9.3g$ ($mean{\pm}SD$) ). Weight gain (WG) and feed efficiency (FE) of fish fed MP, DHSM0 and DHSM30 showed no significant difference among the diet treatments. However, WG and FE of fish fed MP were significantly higher than those of fish fed COMD (p<0.05). Specific growth rate (SGR), protein efficiency ratio (PER) and survival of fish fed all diets were not significantly different among the dietary treatments. Therefore, these results indicate that DHSM could replace up to 30% white fish meal with amino acid supplementation in olive flounder diets for long-term feeding practice at the commercial farm.
BACKGROUND/OBJECTIVES: A number of studies examined secular trends in blood lipid profiles using time series data of national surveys whereas few studies investigated individual-level factors contributing to such trends. The present study aimed to examine secular trends in dietary and modifiable factors and hyper-LDL-cholesterolemia (HC) prevalence and evaluate their associations using time series data of nationwide surveys. SUBJECTS/METHODS: The study included 41,073 Korean adults aged ≥ 30 years from the 2005, 2007-2009, 2010-2012, 2013-2015, and 2016 Korea National Health and Nutrition Examination Surveys. Stepwise logistic regression analysis was performed to select significant factors associated with HC, which was defined as serum LDL cholesterol levels ≥130 mg/dL. RESULTS: The following factors showed a positive association with HC (P < 0.05): for men having higher body mass index (BMI), being married, having an office job, and consuming higher dairy and vegetable oil products; for women having higher age or BMI, having no job or a non-office job, not in a low-income household, and consuming higher dairy products. In the given model, the 2016 survey data showed that a 2 kg/㎡ reduction in BMI of obese persons resulted in a decreased HC prevalence from 30.8% to 29.3% among men and from 33.6% to 32.5% among women. CONCLUSIONS: Based on these findings, it is suggested that primary prevention programs should advocate having proper BMI for Korean adults with a high-risk of HC. However, whether discouraging consumption of dairy and vegetable oil products can reduce HC prevalence warrants further studies with a prospective longitudinal design.
BACKGROUNDS/OBJECTOVES: Family has an impact on dietary intake of children as a proximal food environment and family structures are changing and becoming more diverse. This study was performed to identify the association between family structure and food group intake of children aged 3-18 years in Korea. SUBJECTS/METHODS: A total of 3,217 children with complete data on variables for household information, dietary intake and sampling weights were obtained from 2010-2011 Korea National Health and Nutrition Examination Survey. Children's family structure was classified into 3 groups (Living with both parents, Living with one parent and Living without parents). To evaluate children's food group intake, scores of individual food groups ('Grains', 'Meat, Fish, Eggs and Beans', 'Vegetables', 'Fruits' and 'Milk and Dairy products') was calculated from percent adherence to the recommended servings of the Korean Food Guidance System (KFGS). 'Food group mean score' was obtained by calculating the average of five food group scores. RESULTS: After adjusting for age, sex, number of family members, and household income, children living with both parents had higher scores in 'Fruits' (P < 0.01), 'Milk and Dairy products' (P < 0.05), and mean score of individual food group score (P < 0.001) compared to children living with one parent. Individual food group scores and mean scores of individual food group scores were associated with different socio-demographic factors in study children. Family structure was associated with 'Fruits,' 'Milk and Dairy products' score and mean scores of food group scores. CONCLUSIONS: These results suggested that different approach might be required to solve nutrition problem in children depending on their family structure and other socio-demographic factors.
