The association between obesity and bronchial hyperresponsiveness (BHR) is incompletely characterised. Using the 2006 follow-up of the Tasmanian Longitudinal Health Study, we measured the association between obesity and BHR and whether it was mediated by small airway closure or modified by asthma and sex of the patient. A methacholine challenge measured BHR. Multivariable logistic regression measured associations between body mass index (BMI) and BHR, adjusting for sex, asthma, smoking, corticosteroid use, family history and lung function. Mediation by airway closure was also measured. Each increase in BMI of 1 kg·m−2 was associated with a 5% increase in the odds of BHR (OR 1.05, 95% CI 1.01–1.09) and 43% of this association was mediated by airway closure. In a multivariable model, BMI (OR 1.06, 95% CI 1.00–1.16) was associated with BHR independent of female sex (OR 3.26, 95% CI 1.95–5.45), atopy (OR 2.30, 95% CI 1.34–3.94), current asthma (OR 5.74, 95% CI 2.79–11.82), remitted asthma (OR 2.35, 95% CI 1.27–4.35), low socioeconomic status (OR 2.11, 95% CI 1.03–4.31) and forced expiratory volume in 1 s/forced vital capacity (OR 0.86, 95% CI 0.82–0.91). Asthma modified the association with an increasing probability of BHR as BMI increased, only in those with no or remitted asthma. An important fraction of the BMI/BHR association was mediated via airway closure. Conflicting findings in previous studies could be explained by failure to consider this intermediate step. Airway closure is important, measurable and remediable in the obesity and bronchial hyperresponsiveness relationship http://ow.ly/J79u30dMh8N

中年支气管高反应性和肥胖:来自澳大利亚队列的见解

肥胖与支气管高反应性 (BHR) 之间的关联尚未完全表征。使用 2006 年塔斯马尼亚纵向健康研究的随访,我们测量了肥胖与 BHR 之间的关联,以及它是否由小气道闭合介导或由哮喘和患者性别改变。乙酰甲胆碱挑战测量 BHR。多变量逻辑回归测量体重指数 (BMI) 和 BHR 之间的关联,调整性别、哮喘、吸烟、皮质类固醇使用、家族史和肺功能。还测量了气道闭合的介导。BMI 每增加 1 kg·m−2,BHR 几率增加 5%(OR 1.05,95% CI 1.01–1.09),43% 的这种关联是由气道闭合介导的。在多变量模型中,BMI (OR 1.06, 95% CI 1.00–1. 16) 与 BHR 相关,与女性无关 (OR 3.26, 95% CI 1.95–5.45)、特应性 (OR 2.30, 95% CI 1.34–3.94)、当前哮喘 (OR 5.74, 95% CI 2.79–11.82),缓解哮喘(OR 2.35,95% CI 1.27-4.35),社会经济地位低(OR 2.11,95% CI 1.03-4.31)和1秒用力呼气量/用力肺活量(OR 0.86,95% CI 0.82-0.91)。随着 BMI 的增加,哮喘改变了与 BHR 概率增加的关联,仅在那些没有哮喘或哮喘缓解的患者中。BMI/BHR 关联的一个重要部分是通过气道闭合介导的。先前研究中相互矛盾的发现可以通过未能考虑这一中间步骤来解释。气道闭合在肥胖和支气管高反应性关系中很重要、可测量和可补救 http://ow.ly/J79u30dMh8N 特应性(OR 2.30,95% CI 1.34-3.94),当前哮喘(OR 5.74,95% CI 2.79-11.82),缓解性哮喘(OR 2.35,95% CI 1.27-4.35),社会经济地位低(OR 2.11,95%) CI 1.03–4.31) 和 1 秒用力呼气量/用力肺活量 (OR 0.86, 95% CI 0.82–0.91)。随着 BMI 的增加,哮喘改变了与 BHR 概率增加的关联,仅在那些没有哮喘或哮喘缓解的患者中。BMI/BHR 关联的一个重要部分是通过气道闭合介导的。先前研究中相互矛盾的发现可以通过未能考虑这一中间步骤来解释。气道闭合在肥胖和支气管高反应性关系中很重要、可测量和可补救 http://ow.ly/J79u30dMh8N 特应性(OR 2.30,95% CI 1.34-3.94),当前哮喘(OR 5.74,95% CI 2.79-11.82),缓解性哮喘(OR 2.35,95% CI 1.27-4.35),社会经济地位低(OR 2.11,95%) CI 1.03–4.31) 和 1 秒用力呼气量/用力肺活量 (OR 0.86, 95% CI 0.82–0.91)。随着 BMI 的增加,哮喘改变了与 BHR 概率增加的关联,仅在那些没有哮喘或哮喘缓解的患者中。BMI/BHR 关联的一个重要部分是通过气道闭合介导的。先前研究中相互矛盾的发现可以通过未能考虑这一中间步骤来解释。气道闭合在肥胖和支气管高反应性关系中很重要、可测量和可补救 http://ow.ly/J79u30dMh8N 社会经济地位低 (OR 2.11, 95% CI 1.03–4.31) 和 1 秒用力呼气量/用力肺活量 (OR 0.86, 95% CI 0.82–0.91)。随着 BMI 的增加,哮喘改变了与 BHR 概率增加的关联,仅在那些没有哮喘或哮喘缓解的患者中。BMI/BHR 关联的一个重要部分是通过气道闭合介导的。先前研究中相互矛盾的发现可以解释为没有考虑这个中间步骤。气道闭合在肥胖和支气管高反应性关系中很重要、可测量和可补救 http://ow.ly/J79u30dMh8N 社会经济地位低 (OR 2.11, 95% CI 1.03–4.31) 和 1 秒用力呼气量/用力肺活量 (OR 0.86, 95% CI 0.82–0.91)。随着 BMI 的增加,哮喘改变了与 BHR 概率增加的关联,仅在那些没有哮喘或哮喘缓解的患者中。BMI/BHR 关联的一个重要部分是通过气道闭合介导的。先前研究中相互矛盾的发现可以通过未能考虑这一中间步骤来解释。气道闭合在肥胖和支气管高反应性关系中很重要、可测量和可补救 http://ow.ly/J79u30dMh8N BMI/BHR 关联的一个重要部分是通过气道闭合介导的。先前研究中相互矛盾的发现可以通过未能考虑这一中间步骤来解释。气道闭合在肥胖和支气管高反应性关系中很重要、可测量和可补救 http://ow.ly/J79u30dMh8N BMI/BHR 关联的一个重要部分是通过气道闭合介导的。先前研究中相互矛盾的发现可以通过未能考虑这一中间步骤来解释。气道闭合在肥胖和支气管高反应性关系中很重要、可测量和可补救 http://ow.ly/J79u30dMh8N
