In order to find out the sex- and age-related prevalence rate of allergic diseases in the community. as well as the causes of those diseases. questionnaires were given to 2.415 subjects (1.206 males and 1.209 females) from May to June. 1998. As a second stage. skin tests were given to 452 of the original subjects between July and August. 1998. Finally. from March to November 1999. the results of the tests were compared with those of other countries to make a comparative analysis of epidemiological research on allergic diseases. The results of this study were as follows: The frequency of allergic symptoms by sex was 50.1% in males and 56.7% in females. respectively, which displayed significant difference between males and females(p<.01). By age, the frequency of allergic symptoms in males was highest for those under the age of 9 at 60.6%, whereas in females the highest frequency was between the ages of 30 to 39 at 75.1 %. The relationship between economic level of the subjects and their frequency of allergic diseases showed significant difference (P<.05). There was a high degree of correlation between family history and the frequency of allergic diseases(P<.01). In allergic symptoms, the highest prevalence in both males and females occurred with urticaria, itch and skin rash (33.6% with males and 38.0% with females). Rhinitis, nasal blocking and sneezing had the second highest frequency in both sexes (11.8% of males and 14.0% of females). With regard to the causes of allergic symptoms among the people with allergies, the rate in males was 30.1% in food. 25.0% in pollen, and among females the rate was 30.7% in food, 26.6% in pollen. The frequency of food allergies by sex was 25.6% in males and 25.8% in females, with little difference between males and females, and by age, males of the ages between 40 to 49 and females of the ages between 30 and 39 showed the highest frequency, 31.8% and 32.6% respectively. Among 585 people with food allergies, the sympoms occurring with the allergy in males were 81.5% with urticaria, itch and skin rash. 5.9% with diarrhea and stomachache, and 5.2% with rhinitis, nasal blocking and sneezing. Among females with food allergies, the symptoms were 82.6% with urticaria, itch, skin rash, 9.1% with diarrhea and stomachache, and 4.7% with rhinitis, nasal blocking and sneezing. The type of food most often causing allergy in males was mackerel (6.6%) and females peaches (7.4%). In respect to a positive rate in the skin test by sex, of the 379 males taking the skin test, 21.4% were positive for allergies, whereas 14.7% of the 346 females tested were positive. Among food items found to cause positive allergic reactions, hops had the highest frequency in males (58.9%) and whole eggs had the greatest effect on females (36.4%). The estimated prevalence of food allergies in terms of skin tests was 5.0% of 1.206 males and 3.6% of 1.209 females. In the estimated frequency of food allergy by age group, males of the ages between 40 and 49 and females of the ages from 30 to 39 had the highest rate (6.5% with males and 4.5% with females). In a comparative analysis of epidemiological research on allergic diseases by country group, allergic diseases occurred in 18-50% of each population studied, and the occurrence of allergic diseases when categorized according to symptoms displayed the following as such: allergic rhinitis (3.8-52%), allergic asthma (1.6-17%), and atopy dermatitis (0.33-20.4%). The prevalence of food-related allergies was 6.6-64.9% and the foods causing allergies frequently included milk, eggs, eggs, peanuts, fish, etc.

Objectives: We examined the common allergenic foods, symptoms and management of food allergies in children attending the facilities registered at Center for Children's Foodservice Management in Gangdong-gu, Korea. Methods: The survey was conducted among the directors or head teachers of 186 children's food service facilities with 7,591 children in 2019. The questionnaire consisted of three parts, including general information about food service facilities, information related to food allergies and allergenic foods and symptoms in individual children. Results: The number of children with food allergy was 271 (3.6%), and the proportion decreased with the increase of age. There were 91 children (33.6%) with a medical certificate, and these children had a significantly higher number of allergenic foods and symptoms than those without a medical certificate. Allergenic food groups included meat, fish, eggs and legumes (59.1%), fruits (12.4%), milk and dairy products (8.9%), cereals (7.8%), vegetables (6.2%), processed foods (3.8%) and oils and sugars (1.9%). Eggs accounted for 22.1%, followed by peanut and tree nuts (18.6%), fruits (12.4%), milk and dairy products (8.9%), shellfish (8.6%), vegetables (6.2%), fish (5.7%), cereals (4.3%) and meat (1.1%). The common allergenic foods were eggs, peanuts, walnuts, kiwi, shrimp, milk, tomatoes, mackerel, blue-green fish, peaches, shellfish (clams and abalone), buckwheat, wheat and soybeans. The most common allergic symptoms were skin and mucous membrane symptoms, such as hives, rash, itching and oral angioedema. Meal management for children with food allergies showed different trends depending on the causative food. Conclusions: The objective diagnosis by an allergist should be done for food allergy management in children's catering facilities. A system for systematic meal management of causative foods should be prepared.

Purpose: The purpose of this study was to analyze the effects of a health education program to improve knowledge about environmental health and allergy symptoms among elementary school students. Methods: This study has nonequivalent control group pre-post test design. Participants of this study were 60 elementary students (30 experimental and 30 control) who agreed to participate in the study. The education program consisted of information on environmental health and allergies, the atmosphere, indoor environments, food and allergies, and activities with parents. The program was carried out one time (50 minutes) per week during 6 weeks. Knowledge and symptoms of allergies were recorded before and after the program among both groups. The collected data were analyzed by ANCOVA and t-test using SAS program. Results: There was a significant increase in knowledge about allergies in the experimental group compared to the control group, but allergic symptoms were similar in the two groups. Conclusion: These findings suggest that environmental health education programs are effective in the area of school health nursing for increasing knowledge about environmental health and allergies. Further research is needed to develop programs for reducing allergic symptoms as an environment health problem among children.

A food allergy is described an adverse immunological reaction to a food item. It is increasingly common problem among infants, children, teenagers, and adults worldwide. This study examines food allergy knowledge, attitudes, practices, and health consciousness among college students studying food and nutrition and childhood education. A total of 235 food and nutrition and childhood education college students participated in the survey. According to the results, 41.3% of the respondents were aware of legal obligations associated labeling food items for food allergy; 14.0% were diagnosed with food allergy by their doctor; and 10.2% knew about food allergy symptoms. Food and nutrition students were more knowledgeable than childhood education students. The mean for food allergy attitudes was 4.22, and the score for food and nutrition students was higher than that for childhood education students. The mean for food allergy behaviors was 2.16, and the score of food and nutrition students was higher than that of childhood education students. The importance of food allergens was significantly higher than performance. These results suggest that, to improve the management of food allergies in foodservice operations, education programs regarding food allergies should be provided food and nutrition and childhood education students.

Food allergy is a chronic disease that is increasing all over the world, and it can even lead to a loss of life. To prevent any incidents resulting from food allergies, most countries keep strengthening their food allergen labeling requirements domestically and internationally, with a constant monitoring system against undeclared allergens and recall of offending products. In order to avoid economic losses to industry and damages to international relations from undeclared allergens, it is necessary to confirm each country's regulatory policy on food allergen labeling prior to exportation. Another required action is to try for a reduction of the cross-contamination risk of the allergens during manufacturing and storage, which should be verified by using an accurate and reliable analysis of food allergens. This paper is intended to provide an introduction to the regulation of food allergen labeling by country, allergen management methods to avoid cross-contamination, and allergen detection methods using ELISA, PCR, and LC/MS. Changes of allergenicity during thermal or nonthermal processing also will be investigated in our review. This review will be helpful for the food industry to better understand patients suffering from food allergies and to manage food allergens in food manufacturing.

Food allergies affect 7~8% of infants and young children, and their prevalence appears to have increased in recent years. Food allergy refers to an abnormal immunological reaction to a specific food. These reactions can be recurrent each time the food is ingested. Food allergy manifests itself with a wide spectrum of clinical characteristics including IgE-mediated diseases as immediate reactions, non-IgE-mediated disorders as delayed reactions, and mixed hypersensitivities. As a consequence, the clinical picture of a food allergy is pleomorphic. A well-designed oral food challenge is the most reliable diagnostic test for infants and young children whose clinical history and physical examination point towards a specific food allergy. Food specific IgE antibody tests (RAST, MAST, skin prick test, Uni-CAP, etc) are an alternative tool to determine oral food challenge for IgE-mediated disorders, but not for non-IgE-mediated allergies. Moreover, parents often impose their children on unnecessary diets without adequate medical supervision. These inappropriate dietary restrictions may cause nutritional deficiencies. This review aims to introduce clinical perspectives of food allergy in infants and young children and to orient clinicians towards different strains of diagnostic approaches, dietary management, and follow-up assessment of tolerance development.

Although there has been a steady increase in the prevalence of food allergies worldwide in recent decades, no effective therapeutic strategies have been developed. Modulation of the gut microbiota composition and/or function through probiotics has been highlighted as a promising target for protection against food allergies. In this study, we aimed to investigate the allergy-reducing effects of a probiotic mixture (P5: Lactococcus lactis KF140, Pediococcus pentosaceus KF159, Lactobacillus pentosus KF340, Lactobacillus paracasei 698, and Bacillus amyloliquefaciens 26N) in mice with ovalbumin (OVA)-induced food allergy. Administration of P5 significantly suppressed the oral OVA challenge-induced anaphylactic response and rectal temperature decline, and reduced diarrhea symptoms. Moreover, P5 also significantly inhibited the secretion of IgE, Th2 cytokines (interleukin (IL)-4, IL-5, IL-10, and IL-13), and Th17 cytokines (IL-17), which were increased in mice with OVA-induced food allergy, and induced generation of CD4+Foxp3+ regulatory T cells. These results revealed that P5 may have applications as a preventive agent against food allergy.

Purpose: This study investigated the association between sleep problems and food allergies (FAs) in Chinese preschoolers and assessed whether there is a difference in this association among children with/without siblings. Methods: A cluster-stratified sampling approach was employed to select four districts in Chongqing based on demographic considerations. A total of 16 kindergartens (n = 966 parents) participated in this study. Parents completed the Children's Sleep Habits Questionnaire (CSHQ) and a standard FAs questionnaire. Analysis of covariance and multiple logistic regression were used to assess the associations between sleep problems and FAs after adjusting for relevant confounders. Results: The study found that 16.3% of children had FAs, with eggs, shellfish, and fruit being the most common allergenic foods. The prevalence of FAs was significantly higher in single children (20.63%) than in children with siblings (13.36%). A total of 70.39% of children had CSHQ scores above the clinical cut-off for sleep disorder. Factor analysis revealed five underlying dimensions from the CSHQ. Factor scores, except for the 'difficulty morning waking' factor, were not significantly different between the two groups. Remarkably, the factor scores of 'parasomnias' and 'sleep anxiety' were significantly higher when children had both siblings and FAs. For all subjects, the odds ratios (ORs) of FAs significantly increased with the presence of sleep disorder (OR, 2.35; 95% confidence interval [CI],1.50-3.68) and 'difficulty falling asleep' (OR, 1.34; 95% CI, 1.22-1.48). The subgroup analysis showed that the probability of FAs significantly increased with the 'difficulty falling asleep' (OR, 1.32 vs. 1.38) and sleep disorder (OR, 2.48 vs. 2.14) in children with and without siblings, respectively. The 'parasomnias' was positively associated only with children with siblings. Conclusion: This study suggests that children with siblings might be more susceptible to FAs when accompanied by certain sleep problems. Further studies are warranted to address the underlying dimensions and possible mediation effects of having siblings with sleep problems.
