The aim of this study was to investigate the association of CD36, a class B scavenger receptor, rs6969989 polymorphism with the serum lipid profiles in Korean women, together with their modulation by oily fish consumption. Subjects were participants from the Korean Genome Epidemiology Study (KoGES), which was initiated in 2001 as a large-scale. A total of 4,210 women aged 39 to 70 were included in this study. Data were collected using self-administered questionnaires, anthropometric measurements, and blood chemical analysis. Dietary intake was analyzed using a semi-quantitative food frequency questionnaire. The minor allele frequency for rs6969989 was found in 12% of this population. Homozygotes minor G allele at the rs6868989 exhibited significantly higher high density lipoprotein cholesterol (HDLC) concentrations (P-trend=0.043) and lower fasting glucose (P-trend=0.013) than major allele A carriers. The risk of low HDL-C was significantly lower in homozygotes for the G allele than the A allele carriers (P-trend=0.032). Gene-diet interaction effects between rs6969989 and oily fish intake were significantly associated with the risk of dyslipidemia (P-interaction=0.004). Subjects with homozygotes minor G allele and high oily fish intake generally had a lower risk of dyslipidemia than did those with major allele homozygotes and low oily fish intake. These findings supported that oily fish consumption may modulate the contributions of CD36 rs6969989 on genetic predisposition to the risk of dyslipidemia.
In order to provide basic data for the means to improve food situation and nutritional status of those supported by the National Basic Livelihood Security System (NBLSS), we examined household food insecurity and nutritional status of children under the support of NBLSS. This study included 209 children aged 3-12 years (99 boys and 110 girls) and their caretakers. We measured house food insecurity using Radimer/cornell Scale, children's body sizes and nutrient intake by semi-quantitative food frequency questionnaire, and caretakers' nutritional management skills. Only 9.6% of the households were in food secured (FS) while 8.1% were in household food insecured, but without hunger (HFI), 42.1% were in adult food insecured with hunger (AFI), and 40.2% were in child hungry (CH). Important predictors of food security were nutritional management skills of the caretakers as well as their education, but neither income nor food expenditure of the households. Mean energy intake of the children was 86.0% of the Korean Recommended Dietary Allowance (RDA). Intakes of protein, phosphorous, vitamin A and B$_1$ were relatively high ranging from 112.3% to 124.4% of the RDAs while those of calcium, iron, niacin, vitamin C were low showing 74.8-83.3% of the RDAs. Height, weight and weight/height ratio were close to the reference levels. Lower nutrient intakes of children were observed as the households were more food insecured. However, nutrient intakes and body sizes of children did not differ as a function of household socioeconomic status representing by income, food expenditure and caretakers' education. Results of this study suggest the importance of food security and nutritional management skills for the children's nutrient intakes. Concerning this matter, a need for nutrition education in the program for NBLSS was discussed.
Women have a greater incidence of coronary heart disease (CHD) after menopause. This relates to hormone imbalance-induced changes in known CHD risk factors, especially hyperlipidemia. The purpose of this study was to explore d1e differences in food consumption and food sources of nutrients in the Korean diet between postmenopausal women aged 50-74 years with normocholesterolemia(NC) and those with hypercholesterolemia(HC). Each subject was either classified as part of the NC group (n=39, serum total cholesterol con. <200 mg/$dl$) or the HC group (n=31, serum total cholesterol con. $\geq$240 mg/dl) based on the Guideline for Korean Hyperlipidemia.l Diet was assessed through a validated semi-quantitative food frequency questionnaire. Consumption of foods such as biscuits and/or crackers, squid and eggs was significantly (p<0.05) higher in the HC group than in the NC group. On the other hand, consumption of potatoes/starches and carrots was significantly (p<0.05) lower in the HC group than in the NC group. There was no significant difference between the two groups in terms of the consumption of legumes and legume products containing phytoestrogen and we could not find a relationship between legumes and legume products and serum cholesterol levels. Consumption of green tea tended to be lower in the HC group than in the NC group. Major sources of cholesterol, cholesterol-saturated index and vitamin A in the diets of the HC group consisted of foods high in cholesterol. Our results confirm that postmenopausal women with hypercholesterolemia in Korea tend to consume cholesterol-rich foods and dishes.
In order to examine nutritional and behavioral risk factors of atopic dermatitis (AD) in Korean preschoolers, we analyzed data on 144 children aged 3-6 years with AD and their 434 healthy counterparts. The data included breast-feeding history, current weight, food behaviors assessed by the Mini Dietary Assessment (MDA), food intake by a semi-quantitative food frequency questionnaire, and behavior problems by the Preschool and Kindergarten Behavior Scale (PKBS). Multivariate logistic regression analyses were performed after controlling for preschool location and child's age, gender and total energy intake, as appropriate. There was no group difference of child and household characteristics. Breastfeeding history was related to lower AD risk (OR = 0.63, 95% Cl = 0.40-0.99), yet no statistically significant association was found with overweight status. Regarding food behaviors, AD risk was lower in children who drank milk at least one cup per day (OR = 0.52, 95% Cl = 0.35-0.78) and had regular meals (OR = 0.62, 95% Cl =0.42-0.92). Moreover, there were lower risks of AD in the second (OR =0.48, 95% Cl = 0.28-0.82) and the highest (OR = 0.55, 95% Cl = 0.32-0.94) intake quartiles as compared with the lowest quartile of kimchi intake. Similarly, AD risk was lower in the highest quartile of rice (OR = 0.51 Cl = 0.28-0.93) and the second quartile of fruit (OR =0.45, 95% Cl = 0.25-0.82) intakes. AD children had more problems in social interaction (OR = 1.97,95% Cl = 1.26-3.07) and independence (OR = 1.60, 95% Cl = 1.01 -2.54) measures than the healthy controls. Likewise, AD children tended to show more problem behaviors such as anxiety (OR = 1.63, 95% Cl = 0.99-2.69). Our results suggest that nutritional and behavioral dimensions are related to AD risk, yet the case control study design may preclude generalization of these results.
Objectives: While recent studies showed that coffee consumption reduced the risk of all-cause mortality, no study has examined the effect of coffee consumption on all-cause mortality related to sleep disorders. We aimed to examine whether sleep-related disorders would differently affect the association between coffee consumption and the risk of all-cause mortality among 8,075 adults aged 40 to 69 years. Methods: In a prospective cohort study, the study participants were biennially followed up for 12 years from 2001 to 2012. On each follow-up visit, the participants underwent comprehensive tests including anthropometric examinations, interviewer-administered questionnaires, and biochemical tests. Coffee consumption frequency and the amount were measured using a semi-quantitative food frequency questionnaire. Using death certificate data from Korean National Statistical Office, the vital status of each study participant was identified. Sleep-related disorders were examined with interviewer-administered questionnaires. We estimated Hazard ratios and the corresponding 95% confidence intervals from Cox Proportional Hazard models. Multivariable models were established after adjusting for center, total caloric intake, age, gender, body mass index, physical activity, education, smoking, drinking, hypertension, diabetes, total cholesterol, c-reactive protein, energy-adjusted food groups of refined grains, vegetables, fruits, meat, fish, and dairy. Results: Compared with those who had no coffee consumption, participants who had about three cups of coffee per day showed a reduced risk of all-cause mortality, after adjusting for covariates. Those who had a sleep-related disorder showed no significant effect of coffee consumption on the risk of all-cause mortality, whereas those who had no sleep-related disorders showed significantly reduced risk of all-cause mortality. Conclusions: Our findings suggested that approximately three cups of coffee per day would be beneficial to reduce the risk of all-cause mortality only among adults with no sleep-related disorders. Coffee consumption should be prudent for those with sleep-related symptoms.

Objectives: An association between dietary patterns and mental health in children has been suggested in a series of studies, yet detailed analyses of dietary patterns and their effects on ADHD (attention deficit hyperactivity disorder) are limited. Methods: We included 4569 children who had dietary intake data as part of the CHEER (Children's Health and Environmental Research) study conducted nationwide from 2005 to 2010. We assessed ADHD (Attention Deficit Hyperactivity Disorder) by the DuPaul's ADHD Rating Scales and dietary intake by a semi-quantitative food frequency questionnaire. Using intake data, we constructed five dietary patterns: "Plant foods & fish," "Sweets," "Meat & fish," "Fruits & dairy products," and "Wheat based." Results: The overall proportion of ADHD was 12.3%. Boys (17.8%) showed a higher rate of ADHD than girls (6.5%). The total intake of calories (85 kcal) and plant fat (2g) in the ADHD group was significantly higher than that of the normal group. ADHD was significantly negatively associated with dietary habits such as having breakfast and meal frequency, and positively associated with eating speed, unbalanced diet, overeating, and rice consumption. Regarding dietary patterns, the "Sweets" category was relevant to high ADHD risk (OR 1.59, 95% CI: 1.18, 2.15 for Q5 vs. Q1) in a linear relationship. An inverse, non-linear association was found between "Fruits & dairy products" and ADHD (OR 0.55, 95% CI: 0.39, 0.76 for Q4 vs. Q1). Conclusions: Our study confirms both positive and negative associations between diet and ADHD in elementary school age children. Moreover, linear or nonlinear associations between diet and ADHD draw attention to the possible threshold role of nutrients. Further studies may consider characteristics of diet in more detail to develop better intervention or management in terms of diet and health.
Underreporting patterns by the level of obesity have not been fully assessed yet. The purpose of this study was to examine the differential underreporting patterns on cardiovascular risk factor, macronutrient, and food group intakes by the level of Body Mass Index (BMI). We analyzed cross-sectional baseline nutritional survey data from the population-based longitudinal study, the Healthy Women Study (HWS) cohort. Study subjects included 538 healthy premenopausal women participating in the HWS. Nutrient and food group intakes were assessed by the one-day 24-hour dietary recall and a semi-quantitative food frequency questionnaire, respectively. The ratio of reported energy intake (EI) to estimated basal metabolic rate (BMR) was used as a measure of relative energy reporting status and categorized into tertiles. Overweight group ($BMI{\geq}25kg/m^2$) had a higher ratio of EI to BMR (EI/BMR) than normal weight group ($BMI<25kg/m^2$). Normal weight and overweight groups showed similar patterns in cardiovascular risk factors, nutrient intake, and food group intake by the EI/BMR. Fat and saturated fat intakes as a nutrient density were positively associated with the EI/BMR. Proportion of women who reported higher consumption (${\geq}4\;times/wk$) of sugar/candy, cream and red meat groups was greater in higher tertiles of the EI/BMR in both BMI groups. Our findings suggest similar patterns of underreporting of cardiovascular risk factors, and macronutrient and food group intakes in both normal and overweight women.

BACKGROUND/OBJECTIVES: This study was aimed at examining the association between dietary flavanones intake and lipid profiles according to the presence of metabolic syndrome (MetS) in Korean women with type 2 diabetes mellitus (T2DM). SUBJECTS/METHODS: A cross-sectional analysis was performed among 502 female T2DM patients (non-MetS group; n = 129, MetS group; n = 373) who were recruited from the Huh's Diabetes Clinic in Seoul, Korea between 2005 and 2011. The dietary intake was assessed by a validated semi-quantitative food frequency questionnaire (FFQ) and the data was analyzed using the Computer Aided Nutritional Analysis program (CAN-Pro) version 4.0 software. The intake of flavanones was estimated on the basis of the flavonoid database. RESULTS: In the multiple linear regression analysis after adjustment for confounding factors, daily flavanones intake was negatively associated with CVD risk factors such as total cholesterol, LDL-cholesterol, and apoB and apoB/apoA1 ratio only in the MetS group but not in the non-MetS group. Multiple logistic regression analysis revealed that the odds ratio for a higher apoB/apoA1 ratio above the median (${\geq}0.74$) was significantly low in the $4^{th}$ quartile compared to that in the $1^{st}$ quartile of dietary flavanones intake [OR: 0.477, 95% CI: 0.255-0.894, P for trend = 0.0377] in the MetS group. CONCLUSIONS: Dietary flavanones intake was inversely associated with the apoB/apoA1 ratio, suggesting a potential protective effect of flavanones against CVD in T2DM women with MetS.
BACKGROUND/OBJECTIVES: The association between dietary patterns and depression has been reported but the results have been inconsistent. This study was conducted to investigate the association between dietary patterns and depression in middle-aged Korean adults. SUBJECTS/METHODS: The participants were selected from a community-based cohort, a subset of the Korean Genome and Epidemiology Study. Depression was assessed using the Korean version of the Beck Depression Inventory (BDI) and those with a BDI score ${\geq}16$ were defined as having depression. The subjects' food intakes over the year preceding the survey were estimated by using a validated semi-quantitative food frequency questionnaire. Dietary patterns were identified by using factor analysis. Multiple logistic regression was used to assess the association of dietary pattern with depression. RESULTS: Among 3,388 participants, 448 (13.2%) were identified as having depression. We identified two major dietary patterns: 'Healthy' dietary pattern was characterized by high intakes of vegetables, soybeans, mushroom, seaweeds, white fish, shellfish and fruits and a low intake of white rice. 'Unhealthy' dietary pattern was characterized by high intakes of white rice, meats, ramen, noodles, bread and coffee and a low intake of rice with other grains. Compared with subjects in the lowest quartiles, those in the highest quartiles of the healthy dietary pattern had a significantly lower odds ratio (OR = 0.59, 95% CI: 0.42-0.82, P for trend = 0.0037) after adjusting for potential confounders. In contrast, the unhealthy dietary pattern was negatively associated with depression (OR = 1.65, 95% CI: 1.19-2.28, P for trend = 0.0021). CONCLUSION: This results suggest that a healthy dietary pattern (rich in vegetables, soybeans, mushroom, seaweeds, white fish, shellfish, and fruits) is associated with low risk of depression. Whereas an unhealthy dietary pattern (rich in white rice, meats, ramen, noodles, bread, and coffee) is associated with a high risk of depression in middle-aged Korean adults.
The purpose of this study was to evaluate the folate nutritional status of Korean pregnant women and to investigate the relation between folate levels of maternal-umbilical cord blood, placenta tissue, and pregnancy outcomes. The study subjects consisted of 25 pregnant women who have had normal term deliveries. Dietary folate intakes of the pregnants were estimated by semi quantitative frequency questionnaire and the serum and placenta tissue folate level was measured by microbiological analysis. The total folate intakes of the pregnant women was 655.6 ${\mu}$g/d, which was 131.1% of the Korean RDA for pregnants. Maternal serum folate level was 16.18ng/ml, which was significantly lower than that of umbilical cord blood (34.98ng/ml, p<0.05). Mean folate concentration of the placental tissue was 998.0ng/ml, which was the highest compared to maternal and umbilical cord serum level. Umbilical cord serum folate level and placental tissue folate level were highly influenced by maternal serum folate level. The umbilical cord folate levels of the infant group whose birth weight was higher than 3500g were significantly higher than the group whose birth weight was less than 3500g (p<0.05). The placental folate level was significantly higher in maternal group who showed desirable weight gain during pregnancy (11 - 14kg). In conclusion, the birth weigt was related to the umbilical cord folate level and the maternal weight gain was affected by the placental folate level.
