Study Overview
Brief Summary
The purpose of the study is to investigate the prevalence of dysfunctional breathing in children and adolescents with asthma in a hospital outpatient clinic.
Participants are invited to take the Nijmegen Questionnaire and the Asthma Control Questionnaire. The prevalence of dysfunctional breathing defined as NQ score >= 23 is calculated, and demographics are compared between children with and without dysfunctional breathing.
Detailed Description
The purpose of the study is to investigate the prevalence of dysfunctional breathing in children and adolecents with asthma in a hospital outpatient clinic.
Participants are invited to take the Nijmegen Questionnaire and the Asthma Control Questionnaire, during appointments at the outpatient clinic. For this study purpose, each participant only takes the questionnairres once.
Patient data regarding age, sex, asthma medication, lung function, allergic sensitization, method of asthma diagnose, Height, weight and Body mass index is registered from the electronical patient journal.
The prevalence of dysfunctional breathing in the cohort is calculated as the fraction of children with a NQ score >= 23.
The group of children and adolescents with dysfunctional breathing is characterized and compared to the group without dysfunctional breathing, regarding the descriptives mentioned above.

Outcomes
Primary Outcomes
Prevalence of children with dysfunctional breathing defined as Nijmegen Questionnaire ( NQ) Score >= 23
Time Frame: 1 year
Nijmegen Questionnaire is a 16 point questionnairre addressing dysfunctional breathing. Each question is scored from 0 (best) to 4 (worst). NQ score is summarized between 0-64 points. NQ score \>= 23 predicts dysfunctional breathing.
Secondary Outcomes
- Method of asthma diagnose(1 year)
- Age(1 year)
- Sex(1 year)
- The reported use of rescue Beta2 agonist in puffs per week(1 year)
- Forced expiratory volume inthe first second in percent of expected Value. ( FEV1%)(1 year)
- Mask score(1 year)
- Asthma Control Questionnaire ( ACQ5)(1 year)
- Standardised body mass index (BMI_SDS)(1 year)
