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.

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.

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.

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.

Composition of Food Groups Appropriate for Evaluation of Diet Quality of Korean Adolescents: Based on Kant's Minimum Amount

The purpose of this study was to determine composition of food groups appropriate for the evaluation of the quality of total diet or food guide, using the data from the 1998 National Health and Nutrition Survey. Twenty-fourhour-dietary recalls of total 1,110 Korean adolescents aged 13 - 19 years (male 543, female 567) were analyzed for food group consumed (Dietary Diversity Score, DDS), intake patterns of food group, mean index of nutritional quality (mINQ) and nutrient adequacy ratio (NAR). Considering Korean food pattern different from the Americans, this study is to check if Korean 5 food groups with both of oil & sugar group and vegetable &fruit group, and a minimum amount of 30 g in grain group and 15 g in meat group modified from Kant's minimum amount, 15 g in grain and 30 g in meat, could also be appropriate for the diet evaluation of Korean adolescents. Combination of food group and minimum food intake per each food group used in the first trial were categorized into 6 kinds of types: 1) American 5 food groups with Kant's minimum amount as control or 2) American 5 food groups with modified Kant's minimum amount 3) Korean 5 food groups excluded by sugar with the modified amount 4) Korean 5 food groups with modified amount 5) American food groups added oil group with the modified amount 6) American food groups added oil & sugar group with the modified amount. In case of oil group or oil and sugar group, 5 g was quoted for the minimum amount. Correlation between DDS and indices of other diet quality in each type of food group composition were analyzed and the best food group composition was traced by comparing the correlation coefficients of DDS and mINQ or MARs at alpha < 0.01. There was no meaningful difference in weight length index of the subjects of eating or not-eating oil or oil & sugar, while the values of mINQ showed higher in the subjects eating oil but no difference in the subjects eating oil & sugar, compared to the group not-eating, respectively. In comparison of type 1 and type 2, correlation between DDS and indices of other diet quality showed higher in type 1 using Kant's amount. And comparing the type of a combined group of fruit & vegetable (type 3 and 4) and the type of separated group of fruit and vegetable (type 5 and 6). six groups of separated vegetable and fruit showed the higher correlation of DDSs and indices of diet quality. In case of being classified into six groups with oil, DDS showed correlation of r = 0.293 with INQ. While, being classified into six groups with oil & sugar instead of oil only, DDS showed correlation of r = 0.249 with INQ. Accordingly the type 5 with oil is regarded as the better food group type than the type 6 with oil & sugar. Since better result was shown in the composition of six groups with Kant's minimum amount, the comparative analysis on both of type 1 with oil and oil & sugar was finally performed. Then oil added type 1 showed higher correlation of DDS and indices of diet quality. These result indicated that it would be more appropriate to use six food groups with separate vegetable and fruit including oil group (oil-added type 1) rather than oil &sugar group for evaluat ion of dietary quality of Korean adolescents using DDS.

Assessment of Dietary Intake of Preschool Children in Busan : Assessment Based on Food Group Intake / 대한지역사회영양학회지

To assess diet quality by food group intake and to investigate the interrelationship of age, dietary diversity score(DDS), dietary variety score(DVS), dietary frequency score(DFS), food group intake and nutrient intake with food group intake, a dietary survey was conducted with 176 preschool children aged 1 to 6 in Busan using a 24-hr recall method. Food group intake was assessed by food number consumed and intake frequency by six food groups(grain, meat, vegetable, fruit, dairy, sweets group). The mean food numbers consumed and intake frequencies by six feed group were 3.1 and 4.0 in the grain group, 3.6 and 4.0 in the meat group, 3.5 and 4.1 in the vegetable group, 1.0 and 1.1 in the fruit group, 1.3 and 1.5 in the dairy group, 1.4 and 1.4 in the sweets group respectively. As age increased, the intake frequency of the grain group(p<0.05) increased but that of the dairy group(p<0.05) decreased significantly. The DVS and DFS didn't show significant correlations with intake frequency of the dairy group. The grain group intake had significant positive correlations with intakes of the meat, vegetable, and fruit groups. The vegetable group intake had signigicant positive correlations with intakes of the grain and meat groups. The dairy group intake had significant positive correlation with sweets group intake but negative correlations with intakes of the grain and vegetable groups. As the intake frequency of the meat group increased, the NAR(nutrient adequacy ratios) of all nutrients and NAR(mean adequacy ratio) increased significantly. NARs of provein iron, vitamin B1, niacin had the highest correlation with the meat group intake and those of protein, calcium, phosphorous, and vitamin B2 had the highest correlation with the dairy group intake. NARs of vitamin A and vitamin C had the highest correlation with intake of the vegetable and fruit groups respectively. Children with food number consumed and intake frequency of above 6 and 4 in the grain group or above 6 and 6 in the meat group or above 4 and 8 on the v......

A Study on the School Lunch Program Served by the Elementary Schools in Muan: An Analysis of Nutrients and Diversity of Menu / 대한지역사회영양학회지

This study evaluated the quality of meals served by the elementary schools in Muan based on nutrient contents and food diversity. The contents, nutrient densities and nutrient adequacy ratios(NAR) of most nutrients were higher than those calculated from the Korean RDA. However, the content, nutrient density, and NAR of iron were lower than those calculated from the RDA for 10 to 12 year old girls. The content of sodium was somewhat high. The average number of different kinds of food and dishes per meal were 19.2 and 6.0, respectively. The more the number of dishes, the higher the NARs of calcium, calories, niacin, phosphorus and protein. However, the NAR of iron showed no correlation with the number of dishes. The meals belonging to the food group intake pattern containing fruits had more vitamin C and fiber, and less protein, lipid, and phosphorus than those belonging to the food group intake pattern not containing fruits. In conclusion, the quality of nutrition of meals served by school lunch program(SLP) was considered fairly good. However, the nutritionists should consider the iron for 10 to 12 year old girls and cut down the amount of sodium. In addition, unless the children prefer the foods served by SLP or adjust to the general aspects of SLP, SLP can't accomplish its purposes. Therefore, we suggest that nutritionists should survey children's food preference and satisfaction with the general aspects of SLP.

Elderly Nutrition Improvement Program in the community health center : Nutritional evaluation of the elderly using the Index of Nutritional Quality and food group intake pattern

Physiological changes that affect nutrient absorption and utilization occur in older adults, and the collection of nutritional information is an important part of examining the nutrition and health issue. A nutritional survey using the 24-hour recall method was performed to identify nutritional quality and leading patterns of food group intake for protein, vitamin C, P and Fe were over 1, whereas those for vitamin A, B1, B2, niacin and Ca were below 1. The MAR(Mean Adequacy Ratio) was relatively low(0.75). The percentage of energy from carbohydrate, protein, and fat was 65.1, 15.6, and 19.5, respectively, thus the quantities of energy source were ideal. The Older subjects revealed poorer nutrition quality than the younger subjects did. The food group intake pattern of the elderly was not diverse, only 9% of them consumed all food groups in a day. These results suggest that nutritional guiflines for older Koreans should focus on the maintenance of adequate energy intake. In addition, selection of foods with high protein and calcium, such as dairy food, should be emphasized, particularly in the older elderly. Nutrition programs should target individuals at risk of not receiving enough nutrients, like the oldest elderly, and persons with lower education.
