Background: The effect of diet on allergic rhinitis (AR), its severity in children, and whether it modifies AR depending on genetic susceptibility are unknown. We investigated the association between dietary patterns and AR in school children and the influence of diet on AR according to a genetic risk score (GRS). Methods: Totally, 435 7-year-old school children were recruited from the Panel Study on Korean Children. We used dietary patterns (vegetable, sugar, and meat) and dietary inflammatory index (DII) as dietary parameters. AR and its severity were defined by questionnaires about treatment in the previous 12 months and the Allergic Rhinitis and its Impact on Asthma (ARIA) guideline, respectively. A GRS was calculated using 6 single nucleotide polymorphisms for allergic diseases.

“…A recent systematic review of the prevalence rates of allergic diseases in Korea over the past 30 years found continuous increases in the rates of allergic rhinitis, allergic conjunctivitis, atopic dermatitis, and food allergy, although there was no distinct trend in the prevalence of asthma [2]. A notable observation was that the prevalence of allergic rhinitis in children has continuously increased in recent decades [2][3][4].…”

Allergic rhinitis is associated with atmospheric SO2: Follow-up study of children from elementary schools in Ulsan, Korea

Objectives The purpose of this study was to examine the association of allergic rhinitis with air pollutant concentrations using the follow-up data of elementary school children in Ulsan, Korea. Methods All students of four elementary schools in Ulsan, South Korea were surveyed at two-year intervals. The survey used data collected five times, over a nine-year period from June 2009 to April 2018. The questionnaire used in the survey was a modified version of the ISAAC (International society of asthma and allergy of children) questionnaire. A skin prick test (SPT) was performed with 24 standard antigens. To estimate the levels of exposure to outdoor air pollution, the concentrations of sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), carbon monoxide (CO), and particulate matter 10 μm or less in diameter (PM10) were used. As a dependent variable, a history of allergic rhinitis diagnosed by a doctor during the last 1-year was considered. Logistic regression analysis was used to select variables suitable for the statistical model. The selected variables were then used to assess their association with the dependent variable using the generalized estimation equation. Results Among environmental factors, SO2 was associated with a high risk and PM10 was associated with a low risk of allergic rhinitis. The risk of allergic rhinitis from living in a house built within the last year was high, and the risk from living in a multi-family house or apartment was higher than that from living in a segregated house. History of allergic diseases in the family was a high-risk factor for allergic rhinitis. There was a relationship between a history of bronchiolitis at less than 2 years of age and a high risk of allergic rhinitis. Boys were at a higher risk than girls. Conclusion From the follow-up data of elementary school students in Ulsan, Korea, the concentration of SO2, which is an indicator of the degree of industrialization, was related to the prevalence of allergic rhinitis. Among all the risk factors, history of allergic disease in the parents was the most important factor, and the study reconfirmed the results of the previous studies.

“…These two diseases have commonalities in causing oral and respiratory dryness and have been linked to oral health disorders. In studies using allergic rhinitis as a dependent variable 3,8,9) there are no studies on the relevance of oral health.…”

Background: This study aimed to investigate allergic rhinitis and the relationship between allergic diseases, such as asthma and allergic rhinitis, and dental caries and periodontal disease using the raw data from third year of the 6th Korean National Health and Nutrition Examination Survey. Methods: A total of 3,729 subjects aged over 30 years who underwent examination for allergic diseases and an oral health checkup were selected. The data were analyzed using SPSS IBM SPSS ver. 25.0 (IBM Corp., USA). Composite sample cross correlation and composite sample logistic regression analyses were performed using the composite sample general linear model. Results: On examining the socioeconomic characteristics of the subjects suffering from allergic disease and the relationship between allergic disease and oral health, allergic rhinitis was more frequently found in younger subjects with a higher level of education. Periodontal disease and dental caries were more frequent among female, older age groups, lower income earners, and subjects with a lower level of education (p＜0.05). On examining the relationship between the oral health characteristics of the subject and allergic diseases and oral health, allergic rhinitis was more common in subjects with a good oral health status perception than those who answered "bad" to the oral health status question. The community periodontal index of treatment needs (CPITN) score was higher in subjects who answered "poor" to the oral health status question, lower frequency of brushing, and higher in subjects using secondary oral hygiene products; the decayed, missing and filled teeth (DMFT) index was higher in subjects with a perception of poor oral health status (p＜0.05). The DMFT index was high in the asthma group, and the CPITN score was high in the group who answered "no" to allergic rhinitis. Conclusion: There is a relationship between asthma and allergic rhinitis and the DFMT index and CPITN score. Corresponding oral programs for allergic patients need to be developed.
