The dietary intake of whole grains is known to reduce the incidence of chronic diseases such as obesity, diabetes, cardiovascular disease, and cancer. To investigate whether there are anti-adipogenic activities in various Korean cereals, we assessed water extracts of nine cereals. The results showed that treatment of 3T3-L1 adipocytes with Sorghum bicolor L. Moench, Setaria italica Beauvois, or Panicum miliaceum L. extract significantly inhibited adipocyte differentiation, as determined by measuring oil red-O staining, triglyceride accumulation, and glycerol 3-phosphate dehydrogenase activity. Among the nine cereals, P. miliaceum L. showed the highest anti-adipogenic activity. The effects of P. miliaceum L. on mRNA expression of peroxisome proliferator-activated receptor-${\gamma}$, sterol regulatory element-binding protein 1, and the CCAAT/enhancer binding protein-${\alpha}$ were evaluated revealing that the extract significantly decreased the expression of these genes in a dose-dependent manner. Moreover, P. miliaceum L. extract changed the ratio of monounsaturated fatty acids to saturated fatty acids in adipocytes, which is related to biological activity and cell characteristics. These results suggest that some cereals efficiently suppress adipogenesis in 3T3-L1 adipocytes. In particular, the effect of P. miliaceum L. on adipocyte differentiation is associated with the downregulation of adipogenic genes and fatty acid accumulation in adipocytes.
The mother's obesity-related stress and it's association with obesity, food intake, and physical activity in both mothers and their children were determined. Based on self-reports from 470 mothers, obesity stress of mothers were scored by using a five-point Likert scale; only low and high stress scores were used in this study. The perceptions of mothers' weights and their children's weights, mothers' Body Mass Indices (BMI), and preschoolers' Weight-Length Indices (WLI)(%) were also determined. The obesity stress of mothers was significantly associated with the mothers' BMI (high stress: $23.5{\pm}2.4$ vs. low stress: $19.6{\pm}1.7$, p<0.05), but not with their children's obesity. Mothers with a high obesity stress reported a higher percentage of family history of obesity (62.1% vs. 38.3%, p<0.001) than mothers with low obesity stress. Compared to mothers with low obesity stress, mothers with high stress had lower correct-perceptions about their weights (p<0.05) but higher correct-perceptions for their children's weights. Almost 54.5% of mothers with high stress reported watching television 2 or more extra hours per day, compared with 32.2% of mothers with low stress (p<0.05). More children of mothers with high stress had long hours of daily TV viewing than children of mothers with low stress (36.0% vs. 15.3%, $X^2=10.491$, p<0.05). Mothers with high stress reported lower intake of protein-rich foods (p=0.01) and vegetables (p=0.039), but a higher intake of snacks (p=0.009), compared to mothers with low stress. More children of mothers with high stress reported eating high fat snacks or high sugar snacks everyday, but this was not statistically significant. In conclusion, high obesity stress in mothers were greatly associated with their BMI and their inactive life style, including long TV viewing hours per day and unbalanced food intakes, which can lead their children becoming inactive and obese. Special attention is recommended for overstressed mothers and their children, especially those who enjoy long hours of TV viewing.
It was well received that well grounded behavioral theories were important in the development of effective nutrition education programs, but there are only a few programs available for Korean women. The objective of this study was to develop nutrition education programs for childbearing-aged women in Korea. Based on the findings of the needs assessment for the program and theoretical backgrounds, we developed behaviorally oriented tailored nutrition education program including motivation (MT), modifying (MD) and maintenance (MA) stages. The key concepts of the stages were motivation promotion for MT, increasing behavioral capabilities for MD, and strengthening self-management and building favorable environmental condition for MA. The education program was intended to be need in individual nutrition counseling, but it could be well used for group education by developing materials using the relevant contents. The primary users of the program were nutrition educators, however it could be also used by clients as needed. The introductory chapter provided dietary assessment tools and nutrition education tips. MT chapter included subjects such as nutritional status screening, costs of inappropriate nutrition and weight management, benefits of eating right, and activities for motivation promotion. MD stage chapter dealt with topics of healthy weight, knowledges and skills for better eating habits and physical activity status, and activities related to setting tailored behavioral objectives. MA stage focused on facilitating self management skills and building helping relationships. Each stage underlined activities using various educational tools in order to promote active participation of the client (s). For better use of this program, it was recommended to conduct program validation study.
Purpose: Conditions that limit activity constitute one of the important factors that threaten the health of the elderly. This study sought to analyze the dietary habits and nutritional intake status of the Korean elderly who were faced with activity limitations. Methods: Utilizing data from the 2019 Korea National Health and Nutrition Examination Survey, we classified 1,383 elderly people aged 65 and over into 2 groups: those with activity limitations (n = 222, LG) and those without (n = 1,161, NG). We conducted a comparative analysis of the general characteristics, dietary habits, intake of major food groups, energy, and major nutrients. The nutrient adequacy ratio (NAR), index of nutritional quality (INQ), and healthy eating practices were also analyzed. Complex sampling analysis was utilized for all the analyses with energy intake and socio-demographic variables adjusted. Results: The average age (73.8 years) of members of the LG was higher than those of the NG (72.6 years; p = 0.010). A higher percentage of participants in the LG lived alone (28.1%) compared to those in NG (17.2%; p = 0.004). The LG participants tended to regard their health status as "bad" or "very bad" (62.7%) more often than those in the NG (19.3%; p < 0.001). The LG subjects ate breakfast less frequently (p = 0.054) and ate out significantly less often than the NG subjects (p < 0.001). The LG subjects ate more grain (p = 0.001), fewer seeds (p = 0.014) and vegetables (p = 0.039). Carbohydrate made up a large percentage of their energy intake (p = 0.026). The LG subjects had significantly lower NARs of energy (p = 0.021), protein (p = 0.031), and riboflavin (p = 0.037). The LG participants also had a significantly lower rate of healthy eating practices (22.7%) compared to those in the NG (37.8%; p < 0.001). Conclusion: Activity-limited elderly, despite their need for appropriate dietary management, were poorly nourished. They were likely to live alone, thereby making it hard to provide them with social support. Hence, there is a need to provide nutrition education and policy support for the elderly bearing the burden of limited activity.
BACKGROUND/OBJECTIVES: The purpose of this study was to assess the accuracy of a dietary reference intake (DRI) predictive equation for estimated energy requirements (EER) in female college tennis athletes and non-athlete students using doubly labeled water (DLW) as a reference method. MATERIALS/METHODS: Fifteen female college students, including eight tennis athletes and seven non-athlete subjects (aged between 19 to 24 years), were involved in the study. Subjects' total energy expenditure (TEE) was measured by the DLW method, and EER were calculated using the DRI predictive equation. The accuracy of this equation was assessed by comparing the EER calculated using the DRI predictive equation ($EER_{DRI}$) and TEE measured by the DLW method ($TEE_{DLW}$) based on calculation of percentage difference mean and percentage of accurate prediction. The agreement between the two methods was assessed by the Bland-Altman method. RESULTS: The percentage difference mean between the methods was -1.1% in athletes and 1.8% in non-athlete subjects, whereas the percentage of accurate prediction was 37.5% and 85.7%, respectively. In the case of athletic subjects, the DRI predictive equation showed a clear bias negatively proportional to the subjects' TEE. CONCLUSIONS: The results from this study suggest that the DRI predictive equation could be used to obtain EER in non-athlete female college students at a group level. However, this equation would be difficult to use in the case of athletes at the group and individual levels. The development of a new and more appropriate equation for the prediction of energy expenditure in athletes is proposed.
Abdominal obesity (AO) is a strong risk factor for type 2 diabetes and cardiovascular disease, which has shown a remarkable increase in Korea. This study aimed to identify prevalence of AO and related risk factors in Korean adults. A total of 5,132 men and women aged 20-85 years old from the 2001 Korean National Health and Nutrition Examination Survey were included in the analyses. AO was defined as waist circumference >=90 cm in men and >=85 cm in women as proposed by Korean Society of Obesity. Multiple logistic regression was carried out to identify risk factors for AO. Three models were specified: (i) demographic and socioeconomic factors (model 1: age, education, poverty income ratio, employment), (ii) lifestyle factors and covariates (model 2: physical activity, cigarette smoking, alcohol consumption, dietary quality, type 2 diabetes, co-morbidity) and (iii) demographic, socioeconomic and lifestyle factors (model 3). The prevalence of AO was 24.1 % in men, 23.5% in women. High poverty income ratio in men and low education attainment in women were risk factors for AO in model. 1. There was a significant association of AO with alcohol consumption, physical inactivity and dietary quality in men, alcohol consumption and cigarette smoking in women. These factors except alcohol consumption in men became insignificant in model 3. This findings underscore the importance of developing AO prevention programs in Korea that target the at risk groups identified in this study. A program focusing on low income men or less educated women would be more efficient.

This study was conducted to investigate the effects of dietary inclusion of various additives Solid sulfur, fucoidan, and glucan on growth performance and immune responses in Juvenile olive flounder paralichthys olivaceus. Six experimental diets supplemented with : no additives (CON); 0.5 and 1.0% solid sulfur (S); 0.2 and 0.4% fucoidan (F); 0.1% glucan (G) of these additives diet on a dry-matter basis. Fish averaging $8.2{\pm}0.17g$ were fed one of six experimental diets in triplicate groups for 6 weeks. By the end of the feeding trial, weight gain, feed efficiency, specific growth rate, protein efficiency ratio, hepatosomatic index and condition factor of fish fed diet CON were significantly lower then those of fish fed the all additives diets (P < 0.05). In challenge test, fish were infected by intraperitonel injection of 0.1 ml bacterial suspension with Edwardsiella tarda per fish after the feeding trial. As a result fish fed All additive diet showed a lower cumulative mortality then did fish fed CON diet throughout the challenge test. In conclusion, these results indicated that solid sulfur, fucoidan and glucan enhanced the growth, feed efficiency and non-specific immune activity of juvenile flounder and protect the fish against microbial infections.
The purpose of the study was to examine health status and mini nutritional assessment (MNA) according to self-esteem status of elderly in care hospital. The survey was carried out from $13^{th}$ to $31^{st}$ of September, 2014 in five care hospitals. Analysis was performed for 226 subjects. Evaluation criteria included demographics, clinical status, MNA, health-related quality of life (EQ-5D) and self-esteem. The SE I, SE II and SE III groups were divided by self-esteem scores. Data were analyzed one-way ANOVA, Duncan' multiple range test and Pearson's correlation using SPSS 15.0. Education level, religion, dental condition and medical endurance type were significantly different in all groups. Many elderly people were normal BMI ($20.94{\sim}21.67kg/m^2$). Self-esteem significantly increased in order of SE I, SE II and SE III. Mobility, usual activity and anxiety or depression were significantly different in all groups, and EQ-5D of SE II and SE III groups were significantly higher than that of SE I group. Comparison of MNA screening score in elderly patients was as follows : Score for food intake, psychological stress or acute disease, neuropsychological problems, pressure scores or skin ulcer, protein intake, mode of feeding, nutritional status and health status in SE I group were significantly lower than those of SE II and SE III groups. Mobility and drug intake of SE I group were significantly lower than those of SE III groups. Fruit and vegetable intake SE I group were significantly higher than those of SE II and SE III groups. MIS (Malnutrition Indicator Score) was significantly different among the SE I, SE II and SE III groups. We conclude that self-esteem score is positively correlated with protein intake, nutrition status, health status and MIS in elderly care hospital. To improve nutritional status of elderly in care hospitals, systematic nutrition management and self-esteem education program should be implemented.

The purpose of this study is to investigate the relationship between oral health behavior and dietary habits and caries occurrence test and to provide basic data necessary for prevention of dental caries. The average salivary salivary fraction was 8.35ml and the non - amorphous salivary fraction was 2.41ml. The salivary buffering ability was 9.29 and the mean glucose retention time was 15.81 minutes. In the Streptococcus mutans colony count test, low risk group <105 was 80.5% and low risk group <105 was 84.4% in Lactobacillus colony count test. Correlation between caries test scores showed a positive correlation between salivary ratio and non - salivary ratio, saliva buffering ability, non - salivary fraction and glucose retention time, and Lactobacillus. Factors affecting the irritant saliva fraction were alcohol as a factor affecting the ratio of nuts, pork, and non - irritant saliva. In order to prevent dental caries, proper dietary control education should be combined with dental caries activity test and oral health education for proper eating habits.
BACKGROUND/OBJECTIVE: As aging progresses, the number of patients with cognitive impairment also increases. Cognitive function is not generally correlated with diet, and there is debate over that association. Thus, the present study aimed to investigate the association between dietary intake and cognitive function among adults aged 50 years or older. SUBJECTS/METHODS: Between July 2017 and March 2018, 324 adults aged over 50 years from Gwangju Sun-Han hospital participated in a dietary survey. The frequency of food intake and related information were collected using a semi-quantitative food frequency questionnaire (SQ-FFQ) and determining the mini-mental state examination (MMSE) level for 276 participants. The association between dietary intake and cognitive function was assessed by performing logistic regression analysis. RESULTS: Depending on the MMSE score, the participants' age, education level, inhabitation status, medications, alcohol consumption, sleep duration, physical activity, and short geriatric depression scale score were significantly different (P < 0.05). Moreover, those participant characteristics were associated with either decreased or increased odds ratios (OR) for the risk of mild cognitive impairment (MCI). Based on analysis of the participants' intake of 112 detailed food items, which were categorized into 20 food types, intakes of cooked white rice (< 2 times/day compared with ${\geq}3$ times/day) (P < 0.05), properly cooked rice with other grains and legumes (P < 0.001), fruits (P < 0.05), milk (low fat and normal) (P = 0.044), liquid-type yogurt (P = 0.019), and curd-type yogurt (P = 0.015) were found to significantly decrease the OR for the risk of MCI. CONCLUSIONS: Associations were significant between the risk of MCI and the intake of certain food types. Specifically, a moderate intake of cooked white rice and an adequate intake of whole grains, fruits, milk, and dairy products were associated with reduced risks of MCI among adults aged over 50 years.
