Purpose: To investigate the effect of a mother's modeling and feeding practices on the eating behavior of the children. Methods: From April to June 2018, 1,036 young children aged 2 to 6 years and their mothers in Gyeongsan, Gyeongsangbuk-do, were examined for their eating behavior and feeding practices using a verified dietary behavior test (DBT). The children's dietary behavior was classified into four categories: “access evasiveness”, “sensory acuity”, “hyperactivity”, and “irregularity”. The mother's eating behavior was classified into three categories: “pickiness”, “negligence”, and “irregularity”, and feeding practice types were classified into two categories: “responsibility/monitoring”, and “restriction/pressure”. The differences between the groups were tested using the t-test, ANOVA, and Duncan's multiple range test. The influence of feeding practices on the children's eating behavior was analyzed by hierarchical regression analysis while controlling for the mother’s modeling. Results: The problem rates of irregularity, negligence and pickiness in the mother's modeling were 33.7%, 22.8%, and 20.7%, respectively. An analysis of the mother's feeding practices revealed that responsibility/monitoring had a middle, high and low significance in 74.2%, 17.3%, and 8.5% of respondents, respectively and the risk rate of restriction/pressure when guiding children to eat was 15.3%. The problem rates for sensory acuity, access evasiveness, irregularity, and hyperactivity in children were 27.9%, 26.1%, 24.8%, and 22.0%, respectively. Among the four eating behavior characteristics of children, the child's access evasiveness and sensory acuity were more affected by their pickiness rather than the mother's feeding practices, and the child's hyperactivity was more influenced by feeding practices than the mother's eating behavior. The child's irregularity was similarly affected by the mother's eating behavior and feeding practices. Conclusion Since the mother's eating behavior and feeding practices affect the children's eating behavior, a diet improvement program for children should consider not only the nutrition education of children but also the mother's eating behavior and provide the necessary intervention for feeding practices.

Food allergy is an important public health problem affecting 5% of infants and children in Korea. Food allergy is defined as an immune response triggered by food proteins. Food allergy is highly associated with atopic dermatitis and is one of the most common triggers of potentially fatal anaphylaxis in the community. Sensitization to food allergens can occur in the gastrointestinal tract (class 1 food allergy) or as a consequence of cross reactivity to structurally homologous inhalant allergens (class 2 food allergy). Allergenicity of food is largely determined by structural aspects, including cross-reactivity and reduced or enhanced allergenicity with cooking that convey allergenic characteristics to food. Management of food allergy currently focuses on dietary avoidance of the offending foods, prompt recognition and treatment of allergic reactions, and nutritional support. This review includes definitions and examines the prevalence and management of food allergies and the characteristics of food allergens.

PURPOSE: The present study was performed to determine the factor, either duration or the temperature of heat treatment, exerting maximal and significant influence on the composition and allergenicity of egg white (EW) proteins. METHODS: Raw EW and 4 kinds of heated EW (fried EW, boiled EW for 10 minutes, boiled EW for 30 minutes, and baked EW for 20 minutes at 170degrees C) were prepared, and subsequently protein extraction was carried out. The proteins were separated by SDS-PAGE, and then immunoglobulin E (IgE) immunoblots were performed with the sera of 7 egg-allergic patients. Furthermore, the antigenic activities of ovalbumin (OVA), ovomucoid (OM), and ovotransferrin (OT) in different EW samples were measured by inhibition enzyme-linked Immuno-sorbent assay (ELISA). RESULTS: In SDS-PAGE analysis, the intensity of the protein band at 45 kD (corresponding to OVA) decreased significantly in boiled EW (30 minutes) and baked EW, but no change was observed in the case of boiled EW for 10 minutes. In IgE immunoblots, the IgE response to 34-50 kD (OM and OVA) in boiled EW for 30 minutes decreased significantly, when compared with raw EW and other heated EWs. In inhibition ELISA, a significant decrease in the OVA antigenic activity was observed in boiled EW for 30 minutes amongst other heated EW samples. However, OM antigenic activity in all kinds of heated EW including boiled EW for 30 minutes did not reduce after heat treatment. The OT antigenic activity nearly disappeared in heated EWs except in the case of boiled EW for 10 minutes. CONCLUSIONS: Amongst 4 kinds of heated EWs, the boiled EW for 30 minutes showed the most significant changes both in composition and reduction in allergenicity. Our results revealed that the duration of heat treatment had more influence on the composition and allergenicity of EW proteins than the temperature.

The prevalence of atopic dermatitis (AD), chronic cutaneous disease, has increased rapidly worldwide. Since AD is the most common disease affecting infants, maternal food intake during pregnancy as well as lactation is important. The purpose of this research was to examine the difference in maternal food intake during pregnancy between mothers having children with or without AD. One hundred forty-eight mothers with children aged under 2 years with AD (AD group, n=74) or without AD (non-AD group, n=74) were included in the study. Diet during pregnancy was examined using a food frequency questionnaire. There were no differences in the status of mothers' food consumption during pregnancy between the AD and non-AD groups. Mothers in the AD group consumed significantly less white fish (P<0.05), carrot & pumpkin (P<0.01), walnut & pine nut (P<0.05), mandarin & orange (P<0.05), and peach (P<0.05) than those in the non-AD group. As food frequencies were categorized according to <1/month, 1~3/month, 1~6/week, and 1~3/day, lower consumption of carrot & pumpkin (Odds Ratio (OR)=6.67, 95% Confidence Interval (CI)=1.98~22.44), tomato (OR=5.11, 95% CI=1.62~16.08), mandarin & orange (OR=8.64, 95% CI=1.59~46.81), and walnut & pine nut (OR=3.85, 95% CI=1.26~11.77) increased the risk of childhood AD. According to the results, maternal food intakes during pregnancy were significantly different between the AD and non-AD groups. Therefore, further studies are necessary to examine the causal relationship between maternal food intake and prevalence of AD in children.

OBJECTIVES: This study was conducted to develop and validate Eating Behaviors Test form (EBT) for infants and young children, including eating behaviors of their parents and parental feeding practices. METHODS: Draft version of EBT form was developed after a pretest on 83 mothers. It was consisted of 42 questions including 3 components; eating behavior of children, eating behavior of parents, and parental feeding practices. Using these questionnaires, the first survey was conducted on 320 infants and children, 1 to 6 year old, for exploratory factor analysis, and the second survey was collected on 731 infants and children for confirmatory factor analysis. RESULTS: Exploratory factor analysis on 42 questions of EBT form resulted in 3 factor model for children's eating behavior, 3 factor model for parents' eating behavior, and 1 factor model for parental feeding practices. Three factors for children's eating behavior could be explained as follows; factor 1, pickiness (reliability alpha=0.89; explanation of variance=27.79), factor 2, over activity (alpha=0.80, explanation of variance=16.51), and factor 3, irregularity (alpha=0.59, explanation of variance=10.01). Three factors for mother's eating behavior could be explained as follows; factor 1,irregularities (alpha=0.73, explanation of variance=21.73), factor 2, pickiness (alpha=0.65, explanation of variance= 20.16), and factor 3, permissiveness (alpha=0.60, explanation of variance=19.13). Confirmatory factor analysis confirmed an acceptance fit for these models. Internal consistencies for these factors were above 0.6. CONCLUSIONS: Our results indicated that EBT form is a valid tool to measure comprehensive eating and feeding behaviors for infants and young children.

Atopic dermatitis (AD) is believed to be associated with the intake of antioxidant nutrients and fatty acids due to its immunological dysfunction. The purpose of this study was to examine the effects of nutrition education promoting vegetable, fruit, and fish intake on the severity of AD in children. Children with AD aged 6 months to 5 years were randomly assigned into education and control groups, and followed for 1 year. Seventy-six children completed the study (38 for control, 38 for education). The education group received education promoting the intakes of antioxidant-rich foods (vegetables, fruits) and n-3 fatty acid foods (fish). A 24-hour food recall was collected for the diet information. After education, all vegetables (p < 0.001), fruits (p < 0.01), and fish (p < 0.05) intakes per 1000 kcal increased significantly in the education group, whereas only vegetable intake increased in the control group (p < 0.001). The SCORAD index, the severity of atopic dermatitis, decreased significantly in the education group (p < 0.05). Increased consumption of dietary vitamin E was significantly associated with reduction in the SCORAD index, after adjusting for age and gender (p < 0.05). A nutritional education program to increase vegetable, fruit, and fish intake may be effective in reducing the severity of AD, and vitamin E intake may be associated with the decreased severity of AD. More controlled studies on the relationship between these intakes and severity of AD, with intensive diet and/or supplement intervention programs, are needed to obtain conclusive results.

PURPOSE: Serum screening test to detect specific immunoglobulin E (IgE) is an important step for the assessment of potential allergenicity of genetically modified (GM) food. The purpose of this study was to evaluate the usefulness of pooled serum for serum screening instead of individual serum. METHODS: Children with allergic disease were recruited and those who were sensitized to peanut or egg white were selected to obtain their sera. Sensitization to these foods was determined when the level of specific IgE was over 0.35 kU/L by ImmunoCAP. The patients were divided into subgroups according to their level of specific IgE. Raw proteins were extracted and immunoblot analysis was performed to compare the immunoreactivity between individual serum and pooled serum. RESULTS: Pooled serum from peanut-sensitized allergic children showed all the bands which were shown in immunoblot analysis by using individual serum and peanut protein extract. These findings were demonstrated both in pooled serum with low level of peanut-specific IgE and in those with high level of peanut-specific IgE. Likewise, there was no difference in the immunoreactivity between individual serum and pooled serum from egg white-sensitized allergic children. CONCLUSION: Pooled serum can be used as an alternative to individual serum for the serum screening in the allergenicity assessment of GM food.

PURPOSE: To investigate the effect of eating behavior on nutritional status according to temperament type.METHODS: One thousand one hundred three preschool children aged 2 to 6 years in Gyeongsan, Gyeongsangbuk-do from April to June 2018 were surveyed about their eating behavior and nutritional status using DBT (Dietary Behavior Test) and NQ (Nutrition Quotient) which are proven tests. The dietary behaviors of the children were classified into four categories: approach avoidance, sensory sensitivity, hyperactivity, and irregularity. NQ scores were divided into five categories: balance, diversity, moderation, regularity, and practice.RESULTS: The mean of the children's age was 3.42 ± 1.4 (596 boys and 507 girls). The percentage distribution of the NQ grade was as follows: 5.5% (highest), 12.5% (high), 47.1% (medium), 22.2% (low), and 12.6% (lowest). The risk group of approach avoidance and sensory sensitivity had significantly (p < 0.001) lower scores than the normal group in balance factor (51.9 ± 12.0 vs. 57.8 ± 15.9 in approach avoidance type, 52.6 ± 17.6 vs. 57.7 ± 15.9 in sensory sensitivity type) and diversity factor (32.5 ± 24.4 vs. 50.1 ± 22.4 in approach avoidance type, and 32.5 ± 24.0 vs. 50.7 ± 22.2 in sensory sensitivity type). The scores of the hyperactivity risk group were significantly lower in moderation factor (78.2 ± 12.1 vs. 81.2 ± 11.9), and those of the irregular risk group were significantly lower in variety (35.9 ± 24.5 vs. 48.8 ± 23.2), regularity (57.6 ± 37.1 vs. 66.1 ± 17.6), and practice (57.1 ± 19.4 vs. 65.1 ± 22.5) factors than the normal group (p < 0.001). Especially, the risk group of approach avoidance and sensitivity type had significantly (p < 0.001) lower intakes of whole grain, fruit, bean and bean products, vegetables, and Kimchi.CONCLUSION: This present study suggested that the eating behavior based on temperament of demanding preschool children affected food choice resulting in food consumption diversity of children. Therefore, it is important to provide customized nutrition education programs based on temperament type.

Purpose: Childhood obesity has become a social problem due to the social distancing necessitated by the coronavirus disease 2019 pandemic. This study aimed to identify the dietary problems of obese children through various dietary assessment methods and to confirm the usefulness of each method. Methods: The subjects were 88 students in the 4th to 6th grade of elementary school who participated in the nutrition camp organised by the Busan Metropolitan Office of Education, 2020. To evaluate dietary problems and assess diet quality, 24-hour meal records, monthly food intake frequency, and Dietary Screening Test (DST) data were analyzed. Results: Of the subjects, 15.7%, 30.3%, and 53.9% were normal weight, overweight, and obese, respectively. The average age was 11.77 ± 0.77 years and the average body mass index was 23.96 ± 3.01 kg/m 2 . It was observed from the 24-hour meal record method that the overweight and obese subject groups consumed fewer green vegetables (p < 0.001) and white vegetables (p < 0.01) than the normal weight group. In the monthly food intake frequency method, the consumption of ramen (p < 0.01), snacks (p < 0.05), and sausages (p < 0.05) were high in the obese group, and that of anchovies, broccoli, and sweet pumpkin was high in the normal group (p < 0.05). The comparative data from the DST revealed that the overweight and obese groups had less vegetable intake than the normal weight group (p < 0.01) and had higher intakes of dairy products, fast food, and sweet snacks (p < 0.05). Conclusion The usefulness of each method in the dietary evaluation of obese children was confirmed. To address the problem of obesity, it is necessary to evaluate the dietary problem and approach it with a customized solution tailor-made for the individual subject.

This study was undertaken to analyze the growth, nutritional, and dietary risk factors of elementary school students belonging to the Busan Metropolitan City Office of Education and provide the basic data needed to develop an underweight and obesity prevention program. In 2021, BMI and Dietary Screening Test (DST) data of 4,046 children surveyed by the Nutrition Education Experience Center’s “Diagnosis System” of the Busan Regional Office of Education were analyzed. The DST consists of 36 questions about lifestyle habits, meal quality, meal regularity, snack quality, and eating behavior. Of the children included, 6.8% were underweight, 65.4% were normal weight, 13.4% were overweight, and 14.4% were obese. Children in the obesity group had shorter sleep and meal times (P＜0.001), lower vegetable and fruit consumption frequencies (P＜0.001), higher fast food consumption frequencies (P＜0.001), higher rates of skipping meals (P＜0.01) and breakfast (P＜0.001), and more frequently used smartphones and watched TV during meals (P＜0.001). The underweight group had the highest scores for all eating development factors but more frequently had chewing and swallowing difficulties (P＜0.001). The study confirms underweightedness and obesity are present different problems and indicates that nutrition teachers should conduct accurate studies on the eating habits and behaviors of obese and underweight students and provide individually tailored nutritional counseling.
