The correlations between gut microbiota of Muslim Thai lactating women and their dietary intake and gut microbiota of breastfed infants

@#Introduction: Foods and nutrients are essential not only for human health, but also for the balance of gut microbiota. This research aimed to correlate the gut microbiota of lactating women with their food/ nutrient intakes, as well as with their infants’ gut microbiota. Methods: A cross-sectional study was conducted in 27 pairs of mothers and their exclusively breastfed infants. For lactating women, the dietary assessment was conducted by 24-hour recall, and food groups were assessed following the Food and Agriculture Organization’s guidelines, while nutrient intake was analysed using INMUNCAL V3 programme. Gut microbiota of mothers and infants were measured in stool samples using fluorescent in situ hybridisation technique. Results: It was found that energy intake of mothers was only 66% of the recommended Thai Dietary Reference Intakes (DRIs). Most micronutrient and dietary fibre intakes were below the Thai DRIs. Vitamin A (VA)-rich fruits and vegetables food group correlated positively with Lactobacillus species (spp). The association between gut microbiota and nutrient intake of lactating women showed that total protein, phosphorus, and VA were positively correlated with Bifidobacterium spp.; while β-carotene and vitamin C were also positively correlated with Lactobacillus spp. In contrast, consumption of eggs and calcium correlated negatively with Clostridium spp./ Enterobacter spp. Bifidobacterium spp. and Lactobacillus spp. of lactating women and breastfed infants showed strong correlations. Conclusion: Food and nutrient intakes of lactating women were correlated with their Clostridium spp./Enterobacter spp., Bifidobacterium spp. and Lactobacillus spp. Furthermore, Bifidobacterium spp. and Lactobacillus spp. of mothers and breastfed infants showed strong correlations.

The food and nutrient intakes from daily processed food in Korean adults: based on the 6(th) Korea National Health and Nutrition Examination Survey data (2013 ~ 2015) / 한국영양학회지

PURPOSE: The consumption of processed foods has recently been increasing due to changes in the living environment. The purpose of this study was to identify the contribution of processed food to the nutrient intake of adult Koreans. METHODS: A total of 15,760 adult people in the 6(th) National Health and Nutrition Examination Survey (2013 ~ 2015) were included in this study. According to the Korea Food and Drug Administration's classification criteria for processed foods, the 24 hour dietary recall data of the subjects were classified as processed food or natural food. The processed food intake, nutrient intake and major processed food sources by food groups were analyzed. RESULTS: Men consumed more processed foods than did the women. Consumption of processed foods decreased with age, but it increased with the education level and the income level. The total daily processed food intake accounted for 68.1% of the total food intake. The food groups with high processed food intake were beverage, vegetables, cereals and grain products, fruits, and milk and dairy products in this order. The top food source of each food groups were beer, kimchi, bread, processed apple products, and milk. After adjusting for age, gender, and energy intake, all the nutrient intakes and percentage of dietary reference intakes for Koreans, except carbohydrates, were significantly higher in processed foods than in natural foods. The sodium intake from the processed food was 96.3% of total daily sodium intake. The intakes of nutrients from processed foods, excluding vitamins C, dietary fiber, iron, and vitamin A, were higher in men than in women. The intake of sodium from processed foods was highest for people of 30 ~ 49 years of age, and the intake of sodium from processed foods decreased for people over 50. CONCLUSION: Korean adults consumed more processed food than the natural food, consuming more calories and most of the nutrients from the processed food overall total daily intakes. The intake of processed foods is expected to further increase in the future, and nutritional education and research on the ingestion and selection of healthy processed foods are necessary.

Development of a Food Exchange Table and Food Pattern for Nutritionally Balanced Menu Planning / 대한지역사회영양학회지

OBJECTIVES: The purpose of this study was to develop new meal planning tools for a nutritionally balanced diet. METHODS: Based on the food exchange list for diabetes, we adjusted the food group classification system to reflect the suggested nutritional factors for chronic disease prevention and health promotion. We developed a nutritionally balanced dietary profile for adults and compared it with the dietary reference intakes for Koreans (KDRIs) and the food pattern recommended by the Korean Diabetes Association. RESULTS: The newly developed menu planning tools are the LOHAS food exchange table and the LOHAS food pattern. Our recommended daily 1,800 kcal dietary composition for adults is as follows: The carbohydrate food group consists of 4 ‘whole grains’, 3 ‘refined grains’, 2 ‘sugars’, 9 ‘vegetables’, 3 ‘starchy vegetables’, 2 ‘fruits’ and 1 ‘high sugar fruits’. The protein food group includes 3 ‘plant protein foods’, 3 ‘animal protein foods (low-fat)’, and 1 ‘animal protein foods (high-fat)’. The fat food group consists of 2 ‘oils and nuts’ and 1 ‘solid fats’. The total number of calories is estimated at 1,840 kcal and the energy ratio is 62% carbohydrate, 18% protein, 20% fat, 6.8% saturated fat and 13.2% sugars. Using the LOHAS food exchange table, it is possible to estimate values of saturated fat, unsaturated fat, dietary fiber, and sugars besides carbohydrate, protein and fat. It is also possible to compose a dietary design considering carbohydrate, sugars, saturated fat and dietary fiber. The LOHAS food pattern provides benefits for the management of both institutional food services and individual meals, as it can help reduce the levels of saturated fat and sugar intake and help develop healthy meals rich in unsaturated fats and dietary fiber. CONCLUSIONS: The LOHAS food exchange table and LOHAS food pattern are expected to be practical tools for designing and evaluating nutritionally balanced diets.

The Association of Knowledge, Attitude and Practice with 24 Hours Urinary Sodium Excretion among Malay Healthcare Staff in Malaysia

The most effective and affordable public health strategy to prevent hypertension, stroke and renal disease is by reducing daily salt consumption. Therefore, this study aims to determine the association of knowledge, attitude and practice on salt diet intake and to identify foods contributing to high sodium intake. Secondary data analysis was performed on MySalt 2016 data. It was conducted from November 2015 until January 2016 which involving Ministry of Health Staff worked at 16 study sites in Malaysia. Salt intake was measured using 24 hours urinary sodium excretion. Food frequency questionnaire was used to determine the sodium sources. Knowledge, attitude and practice of salt intake were assessed using a validated questionnaire adapted from WHO. Demographic data and anthropometric measures also were collected. Sodium levels of more than 2400mg/day was categorised as high sodium intake. Data were analysed using SPSS software version 21. The mean sodium intake estimated by 24 hours urinary sodium excretion was 2853.23 + 1275.8 mg/day. Food groups namely rice/noodles (33.8%), sauces/seasoning (20.6%), meat and poultry (12.6%) and fish/seafoods (9.3%) were the major contributors of dietary sodium. In multiple logistic regression analysis, being a male (aOR=2.83, 95% CI 2.02 – 3.96) and obese (aOR=6.78, 95% CI 1.98 – 23.18) were significantly associated with high urinary sodium excretions. In addition, those who were unsure that high salt intake can cause hypertension (aOR=1.24, 95% CI 0.65 – 2.36), those who think that they consumed too much salt (aOR=2.10, 95% CI 1.13 – 3.87) and those who only use salt rather than other spices for cooking (aOR=2.07, 95% CI 1.29 – 3.30) were significantly associated with high urinary sodium excretion. This study showed that the main sources of sodium among Malay healthcare staff is cooked food. Poor knowledge and practice towards reducing salt consumption among them contributes to the high sodium consumption. The practice of healthy eating among them together with continuous awareness campaign is essential in order to educate them to minimize sodium consumption and to practice healthy eating.​

The Association between Food Group Consumption Patterns and Early Metabolic Syndrome Risk in Non-Diabetic Healthy People

We investigated the association between dietary habits/food group consumption patterns and early risk of metabolic syndrome (MetS), a main cause for metabolic disease. Study participants were recruited from the health promotion center in Dong-A University Hospital and public advertisement. Study subjects (n = 243, 21–80 years) were categorized into three groups: Super-healthy (MetS risk factor [MetS RF] = 0, n = 111), MetS-risk carriers (MetS RF = 1–2, n = 96), and MetS (MetS RF ≥ 3, n = 27). Higher regularity in dietary habits (breakfast-everyday, regular eating time, non-frequent overeating, and non-frequent eating-out) was observed in the Super-healthy group than in the MetS-risk carriers, and particularly in the MetS subjects. The relationship between food group consumption patterns and MetS-risk related parameters were investigated with adjustment for confounding factors. Fruit consumption was positively associated with HDL-cholesterol, and tended to be negatively associated with waist circumference, triglyceride, LDL-cholesterol, and insulin resistance (IR). The consumption of low-fat meats and fish, and vegetables was negatively associated with hs-CRP. Specifically, the consumption of sea-foods belonging to the low-fat fish was negatively associated with fasting glucose, hs-CRP, and interleukin (IL)-6. Anchovy/dried white baits consumption was negatively associated with fasting insulin and IR. Green-yellow vegetables consumption was negatively associated with fasting insulin, IR, and hs-CRP. On the other hand, sugars and fast-foods were positively associated with LDL-cholesterol. Additionally, fast-foods consumption was positively associated with hs-CRP and IL-6 levels. In conclusion, dietary habits/food group consumption patterns are closely associated with MetS-risk related parameters in Koreans. It may suggest useful information to educate people to properly select healthy foods for early prevention of MetS.

Comparison of the Number of Daily Servings from Different Food Groups in Metabolic Syndrome Patients with the Control Groups.

Aims: This study aimed to compare the number of daily servings intake from different food groups in metabolic syndrome (MetS) patients with the control groups. Study Design: Case control, comparative cross-sectional study. Place and Duration of Study: Endocrinology and Metabolism Research Center, Vali-Asr Hospital, and Clinical Nutrition Department, School of nutritional Sciences and Dietetics, Tehran University of Medical Sciences, from April 2014 to March 2015. Methodology: In this cross-sectional study the number of daily servings intake of seven major food groups including grain, meat, fruit, vegetable, fat and oils, milk and sweets was compared between 50 MetS patients (Group 1) and 50 obese or overweight participants without MetS (Group 2) and 48 normal weight participants without MetS (Group 3). The demographics, anthropometric and biochemical variables were assayed. Feeding and food frequency were collected using a modified food frequency questionnaire. USDA food pyramid was used to classify the food groups. Results: The total and per 1000 kcal daily servings intake from all the aforementioned food groups were significantly different among the study groups (p≤.01). The numbers of daily servings from meat, fruit, vegetable, and milk groups were significantly higher, while, quantity of daily servings by considering fat and oil, sweets and grain groups were significantly lower in the normal weight controls in comparison with the patients suffering from metabolic syndrome and overweight/obese controls, as well (P<.001). No significant difference was noticed by considering all food groups’ consumption between patients with metabolic syndrome and overweight/obese controls (P≥.09). In addition, meat group was categorized to its subgroups including red meat, poultry, fish, tuna, egg, and nuts. The numbers of total and per 1000 kcal of daily servings intake from meat subgroups were respectively higher with regards to nuts, egg, poultry, red meat and fish and tuna subgroup (P≤.07). To illustrate, the normal weight controls had the highest consumption of meat group, which was due to the high intake of nuts, eggs and poultry subgroups. Conclusion: In conclusion, the number of daily servings intake from meat, fruit, vegetable and milk groups were significantly higher, while, fat and oil, sweets and grain groups were significantly lower in the normal weight controls in comparison with the patients with metabolic syndrome and overweight/obese controls. No significant difference was observed among patients with metabolic syndrome and overweight/obese controls.

Evaluation of dietary intake in Korean adults according to energy intake from eating-out: Based on 2013~2014 Korea National Health and Nutrition Examination Survey / 한국영양학회지

PURPOSE: The objective of the present study was to evaluate nutrient and food group intakes in Korean adults according to energy intake from eating-out. METHODS: This study was a cross-sectional study based on the 2013~2014 Korea National Health and Nutritional Examination Survey, and study subjects were 5,186 males (2,151) and females (3,035) aged 19~64 years. Energy intake from eating-out was analyzed using the 24-hour dietary recall method, and groups were classified by quartile according to energy intake from eating-out. RESULTS: Subjects who had more energy intake from eating-out tended to be younger, highly educated, have a higher income, and have higher alcohol consumption. Total energy intake and fat intake density of the highest quartile group of energy intake from eating-out were higher than those of the other groups. However, fiber, vitamin B1, calcium, phosphorus, potassium, and iron intake density levels were significantly lower in the highest quartile group of energy intake from eating-out. The highest quartile group of energy intake from eating-out consumed significantly more meat and beverages compared to the other groups. In addition, regarding diet quality (Index of nutritional quality), significantly lower vitamin B1, calcium, phosphorus, and iron levels were observed in the highest quartile group of energy intake from eating-out compared to those in the other groups. CONCLUSION: In conclusion, in Korean adults, consumption of eating-out decreased dietary quality, including vitamin B1, calcium, phosphorus, and iron levels. Further studies are needed to confirm these findings.

Associations of Colorectal Cancer Incidence with Nutrient and Food Group Intakes in Korean Adults: A Case-Control Study

This study aimed to examine the associations between intakes of various nutrients and food groups and colorectal cancer risk in a case-control study among Koreans aged 20 to 80 years. A total of 150 new cases and 116 controls were recruited with subjects' informed consent. Dietary data were collected using the food frequency questionnaire developed and validated by the Korea Centers for Disease Control and Prevention. Multivariate logistic regression models were used to estimate odds ratios (ORs) and corresponding 95% confidence intervals (CIs) for colorectal cancer incidence. High intakes of total lipid (OR(T3 vs T1) = 4.15, 95% CI: 1.33-12.96, p for trend = 0.034), saturated fatty acid (OR(T3 vs T1) = 2.96, 95% CI: 1.24-7.04, p for trend = 0.016) and monounsaturated fatty acid (OR(T3 vs T1) = 3.04, 95% CI: 1.23-7.54, p for trend = 0.018) were significantly associated with increased incidence of colorectal cancer. High dietary fiber (OR(T3 vs T1) = 0.22, 95% CI: 0.08-0.56, p for trend = 0.002) and vitamin C (OR(T3 vs T1) = 0.38, 95% CI: 0.14-1.05, p for trend = 0.021) intakes were significantly associated with reduced colorectal cancer incidence. From the food group analysis, bread (OR(T3 vs T1) = 2.26, 95% CI: 0.96-5.33, p for trend = 0.031), red meat (OR(T3 vs T1) = 7.33, 95% CI: 2.98-18.06, p for trend < 0.001), milk.dairy product (OR(T3 vs T1) = 2.42, 95% CI: 1.10-5.31, p for trend = 0.071) and beverage (OR(T3 vs T1) = 3.17, 95% CI: 1.35-7.48, p for trend = 0.002) intakes were positively associated with colorectal cancer risk. On the other hand, high intake of traditional rice cake (OR(T3 vs T1) = 0.35, 95% CI: 0.14-0.86, p for trend = 0.024) was linked with lower colorectal cancer incidence. In conclusion, eating a diet high in total lipid, saturated fatty acids and monounsaturated fatty acids is associated with higher incidence of colorectal cancer, whereas a diet high in dietary fiber and vitamin C was found to lower the incidence in Korean adults. Interestingly high traditional rice cake consumption is associated inversely with colorectal cancer incidence, warranting a future study.

Dietary Intake Status among Korean Female Breast Cancer Survivors / 대한지역사회영양학회지

OBJECTIVES: We aimed to evaluate dietary intake among female breast cancer survivors in a cross-sectional study. METHODS: A total of 127 women who had breast cancer surgery at least 6 months before baseline were included. Dietary intake of female breast cancer survivors was assessed through self-reported 3 day-dietary records. To compare dietary intake between breast cancer survivors and general female population without cancer, we selected the 1:4 age matched women from the 2011 Korean National Health and Nutrition Examination Survey (KNHANES). In the KNHANES, participants were asked about their dietary intake using the 24-hour dietary recalls. We also examined whether dietary intake varied by age group, cancer stage, or time since surgery among breast cancer survivors. We used the generalized linear model to compare their dietary intakes. RESULTS: Intakes of total energy, beta-carotene, folate, vitamin C, plant iron and fruits were lower among breast cancer survivors with longer time since surgery compared to those with shorter time (p < 0.05). Breast cancer patients with higher stage at diagnosis tended to consume less legumes (p = 0.01) than those with lower stage. When we compared dietary intake between breast cancer survivors and the general female population without cancer, breast cancer survivors were more likely to consume most of macro- and micro-nutrients in larger quantity (p < 0.05) and adhere to healthier diet characterized by higher intakes of legumes, seed and nuts, vegetables and fishes and shells than the general female population who never had been diagnosed with cancer (p < 0.05). CONCLUSIONS: Our study results suggested that the intakes of nutrients and foods varied by time since surgery and cancer stage among breast cancer survivors and dietary intakes among breast cancer survivors differed from that in the general population. Further prospective studies are warranted to explore the association between dietary intakes of specific food items and survival among Korean breast cancer survivors.

Association between family structure and food group intake in children

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.

Evaluation of Traditional Aspects of School Lunch Menus in Korea by Analyzing Dish Group Composition / 대한지역사회영양학회지

This study was conducted to analyze traditional aspects of school lunch menus in Korea. We conducted a content analysis of menu-related contents included in guidelines for school lunch programs provided by 16 city and provincial education offices. In addition, the data of 10,495 menus for the third week of December 2010 and March, July, October 2011 from 557 elementary, middle, and high school were analyzed by school grade, area, and province. The results showed that there were no specific and detailed guidelines for menu planning in terms of traditional food culture in most of the guidelines for school lunch programs. However, the basic traditional menu composition was maintained in school lunch menus. The percentage of menus including rice and Kimchi was 97% and 95%, respectively, and that including Korean soup was about 72%. However, the frequency of serving Namul, Korean seasoned vegetable dish, accounted for only about 52% of the menus. The percentage of the menus following the traditional food group pattern including such five food groups as rice, Korean soup, Kimchi, Namul, and optional Korean side dish was only about 35%. The percentage of the menus following the traditional food group pattern excluding Namul from the five food groups accounted for about 30%. The traditional food group score, calculated by allocating 1 point to each of the five food groups was 4.06 out of 5 points on average. Elementary schools and schools in rural area and in Jeolla-do province served traditional menus more frequently. In conclusion, school lunch programs need to consider establishing traditional foods-based standards and relevant guidelines for school lunch, particularly for high schools and schools in urban areas and in some provinces.

Trends in the major dish groups and food groups contributing to sodium intake in the Korea National Health and Nutrition Examination Survey 1998-2010

The purpose of this study was to evaluate trends in the sources of dietary sodium intake in a representative Korean population in the Korea National Health and Nutrition Examination Survey (KNHANES) conducted in 1998, 2001, 2005, 2007, 2008, 2009, and 2010. The study consisted of 53,570 men and women aged 7 years or older participating in the KNHANES during the corresponding years. Overall sodium intake and the mean percent contribution of each dish and food group to dietary sodium intake across 1998-2010 were calculated. The means of sodium intake ranged between 4,572.6-5,498.9 mg/d across 1998-2010. The major dish groups contributing to dietary sodium intake were kimchi (1,154.8-1,521.2 mg/d), noodles and dumplings (505.3-760.5 mg/d), soups (465.3-714.8 mg/d), and stews and casseroles (387.0-579.8 mg/d). The combined mean percent contribution from the top four dish groups contributing to dietary sodium intake showed a slight decrease over the period; 64.4% in 1998, 64.5% in 2001, 59.3% in 2005, 58.2% in 2007, 56.3% in 2008, 56.7% in 2009, and 54.4% in 2010. The major food groups contributing to dietary sodium intake were seasonings (1,852.9-2,435.9 mg/d), vegetables (1,425.6-1,792.1 mg/d), grains (482.2-778.1 mg/d), and fish and shellfish (257.2-351.4 mg/d). In addition, the combined mean percent contribution from the top four food groups showed a slight decrease over the period; 92.8% in 1998, 93.2% in 2001, 93.8% in 2005, 92.1% in 2007, 91.7% in 2008, 90.9% in 2009, and 90.7% in 2010. In summary, we did not observe a reduction in dietary sodium intake over time, however, the percent contributions from the top major dish groups or food groups to dietary sodium intake showed a decrease over the last decade.

Differences in Dietary Intakes between Normal and Short Stature Korean Children Visiting a Growth Clinic

This study compared birth stature, parents' stature, and food and nutrient intakes between normal and short stature Korean children visiting a growth clinic. A total of 143 growth clinic visitors agreed to participate in the study. Out of the 143 subjects, 37 children with height below the fifth percentile (short stature group) and 58 children with height above the twenty-fifth percentile (normal group) were included in the study analysis. Data were collected through a survey of parents or guardians of children and anthropometric measurements. The ratio of short stature in either parent was significantly higher in short stature group. The mean intakes of protein, fat, calcium, and iron were lower in short stature children compared to normal children. Among five major food groups, the intake frequency of vegetables and fruits was significantly lower in short stature group and that of meat.fish.egg.legume group was also significantly lower in short stature group. In further analysis categorized into 11 detail food groups, the intake frequency of fruit group and legume group was significantly lower in short stature group. Nutritional counseling should be provided to emphasize adequate intake of various food groups including vegetables, fruits, and legumes to short stature children visiting a growth clinic.

Association between adherence to the Korean Food Guidance System and the risk of metabolic abnormalities in Koreans

Consumption of a diet consistent with dietary guidelines is believed to have a beneficial effect on the prevention of chronic diseases and the promotion of general health. This study was conducted to explore the relationship between adherence to the Korean Food Guidance System (KFGS), which was based on the 2010 revised KDRIs, and the risk of metabolic abnormalities. Five hundred and ninety-six Korean adults between 30 and 59 years of age were recruited by advertisement to the Bundang Jesaeng General Hospital (BJGH), and those not taking regular medications and without diagnoses of fulminant disease were included. Data were collected on anthropometric measurements, diagnostic parameters for metabolic syndrome (MetS), and 3-day dietary intakes from individuals in the study. The number of servings consumed from each food group was compared to the KFGS recommended servings for each of the 6 food groups. Poor adherence to the recommendations for servings of milk and dairy products (OR: 2.038, 1.128-3.682) was associated with a higher risk of MetS, and poor adherence to the guidelines for fruit consumption (OR: 1.849, 1.027-3.329) was associated with a higher risk for the existence an elevated waist circumference. Conversely, the consumption of meat, fish, eggs, and beans above the recommended number of servings was associated with a lower risk of having an elevated waist circumference (OR: 0.523, 0.288-0.950), and the consumption of vegetables above the recommended number of servings was associated with a reduced risk of having elevated fasting glucose (OR: 0.533, 0.298-0.954). These results suggest that adherence to the KFGS guidelines helps to prevent the development of MetS, but this association needs to be confirmed by prospective studies.

Evaluation of reproducibility and validity of food group intakes measured by a food frequency questionnaire for Chinese men / 复旦学报（医学版）

Objective To evaluate the factors influencing the reproducibility and validity of food group intakes measured by a food frequency questionnaire (FFQ) for Chinese men. Methods A total of 214 adult men were randomly selected from the Shanghai Men Health Study (SMHS), an ongoing cohort study conducted in urban Shanghai. Each subject who had completed the first FFQ survey at recruitment took 24-hour dietary recall (24-HDR) surveys which were conducted once a month for 12 consecutive months and a second FFQ at the end of the study. Two FFQs were administered approximately 1.2 years apart. The food items listed in FFQ and obtained from 24-HDR were categorized into 11 food groups. The factors influencing the reproducibility of the FFQ was assessed by comparing the Pearson correlation of intake levels from the two FFQs, while the factors influencing the validity was evaluated by comparing intake levels from the second FFQ with the multiple 24-HDRs. Results A total of 195 men completed all 12 times of 24-HDR and twice FFQ surveys. The median Pearson correlation coefficients of the food groups between the two FFQs in older vs younger age group were 0.62 vs 0.50;in higher vs lower education level group were 0.58 vs 0.50;in higher vs lower income group were 0.51 vs 0.50;in higher vs lower BMI group were 0.50 vs 0.49. The median Pearson correlation coefficients of the food groups between the second FFQ and 24-HDRs in older vs younger age group were 0.61 vs 0.45;in higher vs lower education level group were 0.49 vs 0.47;in higher vs lower income group were 0.43 vs 0.57;in higher vs lower BMI group were 0.48 vs 0.51. Conclusions Age is the main factor influencing the reproducibility of the food group intakes by a FFQ used in the SMHS, while the factors influencing the validity are age and family income.

Comparison of Mineral and Vitamin Intakes According to the Stage of Change in Fruit and Vegetable Intake for Elementary School Students in Chungnam Province

The purpose of this study was to compare the mineral and vitamin intake according to the stage of change in fruit and vegetable intake. The subjects consisted of 256 students, 122 males and 134 females, who are fourth, fifth and sixth grade in an elementary school located in Yeongi-Gun, Chungnam province. The dietary intake was examined by 24 hr dietary recall for 1 day and by food record for 2 days from April 19 to May 01, 2007. Stage of change of intake of fruits and vegetables of the students was categorized into three groups: precontemplation, contemplation and preparation, and action. The subjects at the stage of action took kimchi and vegetables more frequently, and also took more vitamin C as well. But the subjects at other two stages did not show any difference in the intake of any food group and nutrients. Percentage of the male subjects who took less than EAR did not show any significant difference by stage of change in all the nutrients. However, there was gradual decrease in the percentage of female taking less than EAR of vitamin C and vitamin B2. The result concludes that vitamin C intake significantly increase gradually as the stages of behavioral change of fruit and vegetable intake proceed although almost all vitamins and minerals tended to increase.

Obesity and its association with diets and sedentary life style among school children in Seoul, Korea: Compliance with Dietary References Intakes for Koreans food guides

This study compared obese children's food group intakes with the new Dietary References Intakes for Koreans (KDRIs) food guides for 5th-6th grade school children. This study also determined the extent of sedentary life styles related with obesity in this area of children. This is a cross-sectional study of 799 school children. The dietitian sent a survey form describing the project and a questionnaire to the subject's family. The questionnaire included child demographics, family history of chronic diseases, the daily servings of five food groups, such as grains, meat and beans, dairy products, fruits, and vegetables. The daily or weekly hours of physical activity, television viewing, and computer usage were also surveyed. Obesity index (%) of the subjects was calculated, and children with an obesity index (%) equal to or greater than 20 were classified as the obese. Among the 799 participants, 50.7% were female. The percentages of the normal and the obese were 691 (86.5%) and 108 (13.5%) respectively. Obese children reported eating less vegetables (p<0.05), more high sugar snacks (p<0.05), and high fat snacks (p<0.05) than normal children. No significant differences in food servings of grains, meats and beans, and fruits, and dairy products between the normal and the obese were shown. Obese children reported fewer hours of physical activities (p<0.05) and more hours of computer usage (p<0.05) than normal children. Girls showed less likelihood of being obese (odds ratio, 0.575, CI (0.38, 0.87), p<0.05). More hours of physical activity significantly decreased the likelihood of being obese (odds ratio, 0.572, CI (0.35, 0.92), p<0.05). Family history of obesity almost doubled the likelihood of obesity in children (odds ratio, 2.653, CI (1.660, 4.241), p<0.05). In conclusion, frequent snacking, inadequate vegetable consumption, and sedentary lifestyle increased significantly the likelihood of obesity in children, which suggest that obesity intervention in this age group should focuse more on those variables.

Underreporting of dietary intake by body mass index in premenopausal women participating in the Healthy Women Study

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> or =25kg/m2) had a higher ratio of EI to BMR (EI/BMR) than normal weight group (BMI or =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.

Evaluation of Diet Quality according to Food Consumption between Highly Educated, Married, Unemployed and Employed Women

The differences in food consumption between highly educated, married, unemployed and employed women were analyzed by food group and common food item intake, DDS (dietary diversity score), and DVS (dietary variety score) and DVSS (dietary variety score including condiment). In food group intake, the total amount of food intake of the unemployed women (1,554.0 g) were significantly higher than those of the employed (1,477.9 g), while the amount of food from fungi and mushrooms (4.2 g), seaweeds (2.4 g), and fish and shellfish (60.5 g) of the unemployed women was significantly lower than those of the employed. And the amount of meat, poultry and their products (102.8 g), eggs (29.9 g), and animal oil and fats (4.0 g) was significantly higher than those of the employed. Moreover, the common food items of the unemployed women were ranked as eggs (29.7 g), pork (28.9 g), chicken (27.2 g), and beef (26.7 g) at 7, 8, 9, and 10, respectively. When counting the major food groups consumed, DDS = 4 has the highest proportion in both groups (unemployed 47.4%, employed 49.1%). In case of the subjects who had not consumed one particular food group in DDS = 4, dairy group was the first (83%), followed by fruit, meat, and vegetables. This order is same in other DDS levels. In dietary variety score (DVS and DVSS), the average number of foods consumed per day of employed women was higher than those of the unemployed. The level of DVSS in the employed women (31.9), especially, is significantly higher than in the unemployed women (30.6). Consequently, highly educated women should pay more attention to increasing dairy intake, and they have need of various foods, over thirty foods without condiments in their diet every day. In addition, encouraging unemployed women to have a nutritionally balanced diet, and offering nutrition education and guidance, such as appropriate choices about animal foods, are needed.
