초록

서울시 일부 아동 대상의 식품알레르기 유병률과 위험 요인 및 다른 알레르기 질환과의 연관성 조사결과 식품알레르기 의사 진단 유병률은 14.2%, 알레르기 증상을 한번이라도 경험한 아동의 유병률은 20.4%, 최근 12개월 내 증상 경험 유병률은 17.4%이었다. 식품알레르기를 한번이라도 경험한 아동 612명을 대상으로 알레르기 경험 특성을 도출한 결과 대부분 식품 경구 섭취를 통해 발생하였고 증상 유발식품은 난류, 복숭아, 우유, 땅콩, 새우 등이 있었다. 식품알레르기 증상 경험 유병과 12개월 내 주요 알레르기 유발 의심식품 섭취의 위험요인으로는 곡류, 감자류, 패스트푸드, 견과류, 우유 등이 유의한 영향이 있었다. 식품 섭취의 경우 식품알레르기 증상을 경험한 아동일 경우 견과류, 우유 및 유제품, 난류의 섭취 빈도가 낮을수록 위험도가 유의하게 증가하였다. 환경적 위험요인으로 연령, 부모의 알레르기 질환력, 항생제 복용요인이 도출되었으며, 기타 알레르기 질환과도 관련이 있었다. 최근 식품 알레르기의 또 다른 환경적 위험요인으로 다른 연구들에서도 언급되는 요인이기에 이와 관련한 지속적인 연구가 필요할 것이다. 결과적으로 식품알레르기의 경험이 있는 아동은 다른 알레르기 질환으로 이환될 가능성이 상대적으로 높으며, 이에 따라 규칙적인 식품 섭취와 조기진단을 통하여 유발식품을 명확히 알고 제한할 수 있어야 할 것이다. 궁극적으로 이 연구 결과를 통해 서울에 거주하는 아동의 유병률과 증상경험의 특성을 파악하여 효과적인 중재방안을 도출할 기초자료로의 의미가 있을 것이다.

Purpose: This study examined the prevalence of food allergies and allergenic factors in a selected sample of children living in Seoul, Korea, along with their dietary habits, environmental factors, and diseases as risk factors for food allergy. The results of this study will provide basic data for addressing food allergies. Methods: We selected 3,004 pre-school and school-age children, aged 0 ~ 12, in the 25 districts of Seoul as the study sample. Structured self-report questionnaires were administered over a two-month period in July-August 2018, and the children's parents recorded the answers on their children's behalf. The research tools in this study included the Korean version of the questionnaire from the International Study of Asthma and Allergies in Childhood (ISAAC). Results: The physician-diagnosed prevalence rate of food allergies was 14.2%, while 20.4% of the children experienced allergic symptoms at least once and 17.4% reported symptoms within the previous 12 months. The children's symptoms included skin problems (88.1%), gastrointestinal issues (19.2%), oral issues (16.7%), respiratory issues (12.7%), and systemic issues (1.3%). The causes of allergies included eggs, peaches, milk, peanuts, and shrimps. The factors influencing the experience of food allergies were the consumption of cereal (aOR, 1.52; 95% CI, 1.09 ~ 2.10; p = 0.013), potatoes (aOR, 1.88; 95% CI, 1.33 ~ 2.65; p < 0.001), and fast food (aOR, 1.73; 95% CI, 1.10 ~ 2.72; p = 0.017). Having food allergy symptoms was associated with a higher risk of experiencing asthma (aOR, 4.22 95% CI, 3.10 ~ 5.76; p < 0.001), allergic rhinitis (aOR, 2.53; 95% CI, 2.03 ~ 3.15; p < 0.001), and atopic dermatitis symptoms (aOR, 3.56; 95% CI, 2.88 ~ 4.40; p < 0.001). Conclusion: Episodes of food allergies warrant examining regular food consumption and placing dietary restrictions through early diagnosis as these episodes may imply the presence of other allergies. Our findings offer basic insights into the patterns, prevalence and symptoms of children's food allergies in Seoul, and our findings will contribute to identifying effective interventions for food allergies.
