Objectives: The purpose of this study was to estimate the distribution and exposure prevalence of total carbohydrate intake and the carbohydrate-based foods such as rice, noodles, sweet potatoes, sweet drinks, milk and fruits and to characterize intake patterns among obese Korean adults. Methods: Subjects included 137,363 adults aged 40 years or older who participated in a Health Examinees (HEXA) Study. Multiple regression analysis of data from Semi-Quantitative Food Frequency Questionnaire (SQFFQ) identified food sources of carbohydrates. Weight, height and waist circumstance (WC) were measured, and the body mass index (BMI) was calculated. Obesity was defined as $BMI{\geq}25kg/m^2$ and abdominal obesity as $WC{\geq}90cm$ and ${\geq}85cm$ for males and females, respectively. Results: Obese adults appeared to have a higher total carbohydrate intake in the univariate analysis but had eaten less after adjustment for general and lifestyle factors, compared to normal weight adults (OR 0.78, 95% CI 0.73-0.82 for general obesity; OR 0.79, 95% CI 0.74-0.85, for abdominal obesity; P trend < 0.0001, respectively). Based on advance analysis for the food sources of carbohydrates, obese subjects had lower intake of rice (OR 0.86, 95% CI 0.68 -1.09 for general obesity; OR 0.87, 95% CI 0.67-1.13, for abdominal obesity; P trend < 0.0001, respectively) and higher intake of noodles (OR 1.21, 95% CI 1.16-1.27 for general obesity; OR 1.25, 95% CI 1.19-1.32, for abdominal obesity; P trend < 0.0001 respectively). With regard to other food sources of carbohydrates such as milk and fruits, intake was lower among obese compared to normal weight subjects. Conclusions: In the Korean middle-aged and older obesity groups, the intake of carbohydrates and the related foods was lower than in normal weight subjects, except for noodles. We conclude that a higher intake of noodles may enhance weight-gain. Therefore, this study suggested that the guidelines should consider the types of carbohydrate sources and the amount consumed from foods in order to provide proper guidance with regard to control and prevent obesity among Korean adults.

The prevalence of metabolic syndrome (MetS) in Korea has been increasing in adults, as well as in adolescents. Recently the prevalence of MetS in children has been reported to strongly link that of MetS in parents. Families are known to share similar food environment so that eating habits of parents closely resemble that of the children's. Therefore, the aim of this study to examine metabolic risk factors and dietary intake in children by with respect to mother's metabolic syndrome, based on the data from Korean National Health and Nutrition Examination Survey (KNHANES) 2007-2010. Using the household variable and the eldest child per household, 1,341 pairs of mothers and children were selected. The mothers were defined by MetS criteria, and then the children were classified into the following three groups in accordance to the mothers' MetS; children whose mothers had none, 1-2, and 3 or more components of MetS. All dietary data were evaluated using the data from a food frequency questionnaire. The mean age was $42.6{\pm}4.2$ years for the mothers, and $14.9{\pm}2.0$ years for the children. Children whose mothers had 3 or more components of MetS showed a significantly higher prevalence of overweight and higher level of fasting triglyceride; conversely, they showed a lower level of serum HDL-cholesterol compared to the other two groups. Regarding an agreement of food consumption between the mothers and children, most food groups showed high agreement, except in the category of beverages. Regarding the dietary habits and family meals, children whose mothers had 3 or more components of MetS were more likely to skip breakfast and less likely to have family meals at breakfast or snack. In conclusion, the children's metabolic risk factors and dietary factors were different with respect to the status of mothers' MetS. Further studies are necessary to examine the causal effect of family environment in children's health status.

This study investigated the types, forms, and origination of litter found along one hiking course in Moaksan Provincial Park, 'Jungin-ri Course'(entrance-ridge-valley-peak). In addition, a survey was conducted to understand hikers' litter control awareness in order to determine possible backcountry litter control measures. The following are the results of this study: 1. For the litter Sequency investigation, 199 recyclable pieces of litter were found on the mid-slope(61.6%), 89 by the entrance(27.6%), 19 in the valley(5.9%) and 16 on the peak(4.9%). A total of 323 pieces of litter were found. Paper materials were the most common, followed by plastic containers such as PET bottles and yogurt containers. Of particular interest, 288 papers and cans were found on the mid-slope(46.9%). By the entrance, more plastics and bottles were found. 2. There were 614 pieces of flammable litter collected and only 19 pieces of non-flammable. Most of the flammable litter, including snack pacts, plastic bags, processed lumber, cigarette butts, tissues, cigarette boxes, and fabric was found on the mid-slope. 3. Very little food waste was found throughout the whole site proving that the policy prohibiting hikers from cooking and eating at the designated sites has been effective. However, food waste is difficult to find because it naturally decays with time. 4. $X^2$-test was used to find different types of litter and their verified origination frequency. It was found that recyclable litter, and food waste took about 1%. In addition, recyclable litter, especially bottles, was found relatively frequently by the entrance. Flammable litter was found most often at the peak. 5. The questionnaire results showed that 48.2% of the respondents "shorten their hiking journey and purchase food outside the entrance" and 29.6% said that they "bring a packed meal from home". Only 8.2% said that they "cook something when an appropriate location is found". At the Jungin-ri course, a few hikers brought their own food to eat or cook, but most hikers purchased something to eat onsite. 6. The results of the question about having experience littering while hiking showed that 19.3% litter and 79.2% do not. Those that responded "yes" gave various reasons for littering. 63.6% claimed, "there are no designated trash containers". 15.9% said they litter subconsciously. Finally, 3.2% insist that they litter "because food naturally decomposes". 7. As a result of the overall satisfaction according to the Likert scale and the analysis with an average of 14 variables, it was found that the average "toxic litter control convenience" was 2.41 with very low satisfaction. Thus, the results indicate the importance of providing appropriate back country litter control facilities.

The purpose of this study was to examine dietary habits and nutrient intakes according to feeding method during infant period in elementary school students. Subjects were 1,251 elementary school students. Subjects were divided into three groups, breast-fed group (N=508), formula-fed group (N=397), and mixed group (N=346), according to feeding method during infant period. The questionnaire was composed of general characteristics, dietary conditions during infant period, dietary behaviors, and dietary intakes and was completed by children and children's parents. Average age, height, weight, and body mass index were 11.6 years, 139.0 cm, 34.6 kg, and $17.8kg/m^2$, respectively. The formula-fed group showed a smaller proportion of subjects with colostrum feeding (P<0.001) compared to the breast-fed and mixed groups. Frequency of eating snacks was significantly higher in the mixed group than in other groups (P<0.05). There was no significant difference in dietary habit total score and nutrient intakes according to feeding method during infant period. Feeding method in during infant period was associated with dietary habits (milk and vegetable intake habits) up to growth period of elementary school. A longitudinal and systematic study is needed to clarify this relationship.

Adequate nutrients intake and regular eating habit are so important for the students to develop physical and mental health, and they contribute significantly for the development of intellectual capacity. The intake of simple sugar contained in the processed foods is known to have been related not only with such physical problems as obesity and diabetes but also with hyperactivity during growing period. This study analysed the effects of carbohydrate processed snacks on the middle school students' emotional intelligence and intended to demonstrate the correlation and the influence of the foods. The subjects of this study were 476 the 1st grade middle school students sampled from two public middle schools of Gyeonggi Province, Korea. Questionnaire contained 47 questions including the kinds of sugar containing processed foods, the frequency of intake, the frequency of normal diet, and the emotional test. All data obtained in this study were processed by SAS 8.2 program. 77.9% of the students had snacks more than once a day and the favored foods were in the order of bread, cookies, fruit, milk and dairy products, flour foods, ramen and ice cream. Less of the sugar contained processed snacks consumed high emotional intelligence showed(p<0.001). And low intake of carbohydrate processed snacks linked with having more regular meals and the higher levels of emotional intelligence. There was no gender difference in consuming simple sugar containing processed foods, however, out of these foods, carbonated drinks, ramen and pizza affected significantly the emotional intelligence of the male students. It was found that sugar contained processed snacks affect the eating habits like meal skipping and the emotional intelligence. It is determined that the effects of carbohydrate processed snacks on emotional intelligence can not be denied.

In order to thoroughly analyze risk factors of breast cancer (BC) in premenopausal Uruguayan women, a case-control study was carried out at the Pereira Rossell Women's Hospital, Montevideo, where 253 incident BC cases and 497 frequency-matched healthy controls were interviewed on menstrual and reproductive story, were administered a short food frequency questionnaire and undertook a series of body measurements necessary to calculate body composition and somatotype. Odds ratio (OR) coefficients were taken as estimates of relative risk derived from unconditional logistic regression. Among the classical risk factors, only the family history of BC in first degree relatives was significantly associated with risk of premenopausal BC (OR=2.20, 95% CI 1.33-3.62). Interestingly, this risk factor was found to be stronger in women of ages >40 (OR=4.05, 95% CI 2.10-7.81), late menarche (OR= 2.39, 95% CI 1.18-4.85), early age for their first delivery (OR=3.02, 95% CI 1.26-7.22), short time between menarche and first delivery (OR=3.22, 95% CI 1.29-8.07), and with high parity (OR=4.10, 95% CI 1.79-9.36), although heterogeneity was detected only for age and parity. High consumption of red meat was positively associated with the disease risk (OR=2.20, 95% CI 1.35-3.60), in the same way as fried foods (OR=1.79, 95% CI 1.12-2.84). Conversely, a high intake of plant foods displayed a protective effect (OR=0.41, 95% CI 0.26-0.65). Except for hypertension (OR=1.55, 95% CI 1.03-2.35), none of the analyzed components of metabolic syndrome were associated to BC risk. Particular increases of risk for premenopausal BC were found for family history in first degree relatives in certain subsets derived from the menstrual-reproductive history. Preventive strategies could broaden their scope if new studies confirm the present results, in view of the limited prevention measures that premenopausal BC currently has.

The purposes of this study are to estimate the stress level of university students, and to verify the relationships between stress level and drinking behavior. A questionnaire survey was administered to 430 university students in the Gangwon area in Korea from November 5 to November 28, 2008, and data from 391 students were used for the final statistical analysis. The most stressful factor was "Worry about academic achievements" (2.86 by Likert-type 4 point scale). The subjects were divided into two groups, a low stress group (${\leq}65.0$) and a high stress group (${\geq}66.0$), by the mean value (65.1) and median value (66.0) of the stress levels. The drinking frequency was not different between the two stress groups, but the amount of alcohol consumption was significantly different ($P$ < 0.05). The portion of students reporting drinking "7 glasses or over" was higher in the lower stress group than in the higher stress group. In addition, factor 6, "Lack of learning ability", was negatively correlated with drinking frequency and the amount of alcohol consumption ($P$ < 0.05), and factor 3, "Worry about academic achievements", was negatively correlated with the amount of drinking ($P$ < 0.05). The major motive for drinking was "When overjoyed or there is something to celebrate" (2.62), and the main expected effect of drinking was "Drinking enables me to get together with people and shape my sociability" (2.73). The higher stress group showed significantly higher scores on several items in the categories of motives ($P$ < 0.01), negative experience ($P$ < 0.05), and expected effects ($P$ < 0.05) of drinking than the lower stress group. Our results imply that university students at the lower stress level may drink more from social motives in positive drinking environments, while those at the higher stress level may have more problematic-drinking despite their smaller amount of alcohol consumption.

BACKGROUND/OBJECTIVES: Many adolescents in developing countries skip breakfast. Innovative nutrition education (NE) strategies are needed to enhance knowledge and skills related to the breakfasts of adolescents in a low socioeconomic setting. The objective was to evaluate short- and long-term effects of a multi-strategy, school-based NE intervention on adolescents' breakfast-related personal influences and behaviors. SUBJECTS/METHODS: An intervention study with a cluster randomized controlled trial design was conducted in 4 senior high schools in Makassar, Indonesia. The multi-strategy NE intervention was delivered for 3 months. Data were collected using a self-administered questionnaire and a 3-day breakfast recall (face-to-face interview). Wilcoxon, McNemar, and Mann-Whitney tests were used to determine intra- and intergroup differences. RESULTS: Unlike knowledge, improvement was observed in attitude and self-efficacy scores in the intervention groups (IGs) (P < 0.01); however, no significant changes were observed in the control group (CG). More students showed improved motivation in the IG than in the CG (P > 0.05). Changes in breakfast frequency and macronutrient intake from breakfast were greater in the IG than in the CG (P < 0.05). CONCLUSIONS: A multi-strategy NE intervention is effective in producing positive changes in breakfast-related attitude, self-efficacy, and motivation of adolescents from a low-middle socioeconomic setting. The intervention improved breakfast frequency and nutrient intake. This intervention has promise for sustaining the observed changes over the long-term.
