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.
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.

|---|---|---|
| Prevalence of children with dysfunctional breathing defined as Nijmegen Questionnaire ( NQ) Score >= 23 | 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. | 1 year |
| Measure | Description | Time Frame |
|---|---|---|
| Mask score | Because of the ongoing COVID19 pandemic, face mask is acquired in public, and many children are homeschooled. We therefore generated an 8 question survey about the frequency of wearing mask, breathing difficulties while wearing a mask, and weather there is a lock down of school and sports while survey is taken. Questions are scored from 0-3 points, where 0 is Best and 3 is worst | 1 year |

| Asthma Control Questionnaire ( ACQ5) | ACQ5 contains 5 questions regarding asthma symptoms. Each question is scored between 0-6 points, where 0 represents very good asthma control and 6 represents poor asthma control. Total ACQ score is calculates as an average of points. | 1 year |
| Age | Age in years of study subjects | 1 year |
| Sex | Sex of study subjects | 1 year |
| Standardised body mass index (BMI_SDS) | Body mass index is calculated as weight ( kg)/ Height ( m) ^2. As BMI changes with age, BMI standard deviation BMI_SDS is calculated from Danish Reference Material : (Tinggaard J, Aksglaede L, Sørensen K, et al (2014) The 2014 Danish references from birth to 20 years for height, weight and body mass index.

| Forced expiratory volume inthe first second in percent of expected Value. ( FEV1%) | Spirometry is performed according to guidelines. FEV1% is calculated by the spirometry software. | 1 year |
| Method of asthma diagnose | Fraction of subjects where asthma was diagnosed objectively from lung function variability (reversibility to beta2 agonist OR positive exercise challenge OR positive mannitol challenge). Method of asthma diagnose is noted from the electronical patient journal | 1 year |
