BACKGROUND
A relation between gastroesophageal reflux disease (GERD) and asthma has been suggested; however, causality has not been investigated.
OBJECTIVE
This study aimed to delineate the causal relation between GERD and asthma.
METHODS
Participants of the Korean National Health Insurance Service-National Sample Cohort 2002-2013 who were ≥20 years old were selected for this study. In study I, 116,502 patients with GERD were matched in a 1:2 ratio to 233,004 control I participants, and the hazard ratio (HR) of asthma in patients with GERD was analyzed. In study II, 104,146 patients with asthma were matched in a 1:1 ratio to 104,146 control II participants, and the HR for GERD in patients with asthma was analyzed. A stratified Cox-proportional hazards model was used. Subgroup analyses were performed according to age and sex.
RESULTS
In study I, 12.5% (14,595 of 116,502) of the GERD group and 7.8% (18,135 of 233,004) of the control I group presented asthma (P < .001). The GERD group demonstrated a 1.46-fold higher HR for asthma than the control I group (95% confidence interval [CI] = 1.42-1.49, P < .001). In study II, 16.9% (17,582 of 104,146) of the asthma group and 11.9% (12,393 of 104,146) of the control II group presented GERD (P < .001). The asthma group showed a 1.36-fold higher HR for GERD than the control II group (95% CI = 1.33-1.39, P < .001). All age and sex subgroups presented consistent results.
CONCLUSION
GERD and asthma had a bidirectional relation in the study population.
背景
已有研究表明胃食管反流病（GERD）与哮喘之间存在关联；然而，因果关系尚未得到研究。
目的
本研究旨在阐明GERD与哮喘之间的因果关系。
方法
本研究选取了韩国国民健康保险服务-全国样本队列2002 - 2013年中年龄≥20岁的参与者。在研究I中，116502例GERD患者与233004例对照I参与者按1:2的比例进行匹配，并分析GERD患者患哮喘的风险比（HR）。在研究II中，104146例哮喘患者与104146例对照II参与者按1:1的比例进行匹配，并分析哮喘患者患GERD的HR。采用分层Cox比例风险模型。根据年龄和性别进行亚组分析。
结果
在研究I中，GERD组中有12.5%（116502例中的14595例）出现哮喘，对照I组中有7.8%（233004例中的18135例）出现哮喘（P <.001）。GERD组患哮喘的HR比对照I组高1.46倍（95%置信区间[CI]=1.42 - 1.49，P <.001）。在研究II中，哮喘组中有16.9%（104146例中的17582例）出现GERD，对照II组中有11.9%（104146例中的12393例）出现GERD（P <.001）。哮喘组患GERD的HR比对照II组高1.
