초록

목 적 : 최근 20년간 비만과 천식의 빈도가 증가하고 있으며, 비만이 천식의 발병에 영향을 미친다는 보고가 있으나, 비만이 아토피 및 기관지과민성에 미치는 영향에 대해서는 아직 논란이 많은 것으로 되어있다. 따라서 저자들은 학동기 천식 환아에서 체질량이 기관지과민성 및 아토피에 미치는 영향을 알고자 본 연구를 실시하였다. 방 법 : 최근 6년 동안 알레르기 클리닉을 방문한 천식 환아 중에서 메타콜린에 대한 기관지과민성 유발 검사와 알레르기 피부 시험이 가능했던 340명을 대상으로 하여 체질량 지수(body mass index : kg/m2)를 구하여 한국 소아 및 청소년 신체 발육치에 의한 체질량 지수를 판정 기준으로 백분위수를 구하여 저체중군(≤15th percentile), 정상 체중군(15.1-85th percentile), 과체중군(85.1-95th percentile), 비만군(≥95.1th percentile)으로 분류하고 각 단계에서의 기관지과민성, 아토피 및 흡입항원 감작 정도를 비교하였다. 결 과 : 340명의 대상 환아 중 저체중군이 19명(5.6%), 정상 체중군이 178명(52.3%), 과체중군이 70명(20.6%) 그리고 비만군이 73명(21.5%)로 나타났으며, 과체중군 이상의 환아가 143명으로 전체의 42.1%를 차지하였다. 체질량지수가 증가할수록 코골이 증상, 최근 3개월 동안 천명 발생 및 기관지과민성 양성 빈도가 높게 나타났으며, 각 군 사이에 폐기능이 유의한 차이를 확인할 수 있었다. 하지만 아토피 양성 빈도, 감작 항원 종류와 수는 체질량지수와 관련이 없는 것으로 나타났다. 기관지과민성에 미치는 위험요인을 성별에 따라서 확인해 보면 여아의 경우 정상 체중군에 비해 과체중군(OR 5.1; 95% CI 1.6-16.5) 및 비만군에서는(OR 4.9; 95% CI 1.8-13.4) 위험도가 증가하는 것으로 나타났으나, 남아의 경우(OR 1.1; 95% CI 0.5-2.1), (OR 1.7; 95% CI 0.7-2.0)위험도에 영향을 미치지 않는 것으로 나타났다. 결 론 : 천식 환아에서 체질량지수는 아토피와는 연관성이 없었으나 기관지과민성에는 상당한 영향을 미칠 것으로 사료되며, 특히 여아에서 과체중 및 비만인 경우 기관지과민성의 위험도가 높게 나타났다.

Abstract

Purpose : For the past two decades, there has been a significant increase in the prevalence of both asthma and obesity. Obesity may be associated with increasing childhood asthma and atopy. So, we performed this study to know the effects of body mass on bronchial hyperresponsiveness (BHR) and atopy in childhood asthma. Methods : The subjects were, 340 children aged 6-15 years with asthma, visited the Pediatric Outpatient Clinic. There, their heights and, weights were measured and they underwent, pulmonary function tests (PFT), BHR to methacholine and skin prick tests. After determining body mass index (BMI), they were divided into four groups by BMI percentile curve based on gender and age (underweight ≤15th percentile, normal weight 15.1-85th percentile, overweight 85.1th-95th percentile, obesity ≥95.1th percentile). Atopy, allergen sensitization, BHR, respiratory symptoms, PFT were compared between each group. Results : In all subjects, there were 70 (20.6%) and 73 (21.5%) cases in the overweight and obese groups, respectively. Increasing BMI was significantly associated with a higher prevalence of snoring,(P=0.004) wheezing in the perceding three months (P=0.002) and BHR- positive,(P=0.003) but not atopy.(P=0.075) Among the groups classified by BMI percentile, there were significant differences in FEV1 and FEV1/FVC.(P=0.027, P=0.033) Being overweight and/or, obese were significant risk factor for BHR, though only among females (OR 5.1; 95% CI 1.6-16.5, 4.9; 1.8-13.4) not male (OR 1.1; 95% CI 0.5-2.1, OR 1.7; 95% CI 0.7-2.0). Conclusion : Among girls, a higher BMI might be a risk factor for BHR. Higher BMI is not associated with atopy on either boys or girls.
