To estimate the prevalence of dysfunctional breathing in adults with asthma treated in the community.
Postal questionnaire survey using Nijmegen questionnaire.
One general practice with 7033 patients.
All adult patients aged 17-65 with diagnosed asthma who were receiving treatment.
Score >/=23 on Nijmegen questionnaire.
227/307 patients returned completed questionnaires; 219 (71.3%) questionnaires were suitable for analysis. 63 participants scored >/=23. Those scoring >/=23 were more likely to be female than male (46/132 (35%) v 17/87 (20%), P=0.016) and were younger (mean (SD) age 44.8 (14.7) v 49.0 (13.8, (P=0.05). Patients at different treatment steps of the British Thoracic Society asthma guidelines were affected equally.
About a third of women and a fifth of men had scores suggestive of dysfunctional breathing. Although further studies are needed to confirm the validity of this screening tool and these findings, these prevalences suggest scope for therapeutic intervention and may explain the anecdotal success of the Buteyko method of treating asthma.
评估社区中接受治疗的成年哮喘患者功能失调性呼吸的患病率。
使用奈梅亨问卷进行邮寄问卷调查。
一家拥有7033名患者的普通诊所。
所有年龄在17 - 65岁、已确诊哮喘且正在接受治疗的成年患者。
奈梅亨问卷得分≥23分。
307名患者中有227名返回了完整问卷；219份（71.3%）问卷适合分析。63名参与者得分≥23分。得分≥23分的女性比男性更常见（46/132（35%）对17/87（20%），P = 0.016），且年龄更小（平均（标准差）年龄44.8（14.7）对49.0（13.8），P = 0.05）。英国胸科学会哮喘指南不同治疗阶段的患者受影响程度相同。
约三分之一的女性和五分之一的男性得分提示存在功能失调性呼吸。尽管需要进一步研究来证实该筛查工具及这些发现的有效性，但这些患病率表明有进行治疗干预的空间，且可能解释了布泰科哮喘治疗方法取得的传闻中的成功。
