Future studies should analyze the severity of airflow obstruction with well-established lung function questionnaires.
The combined analyses used original data including measures of lung function, and questionnaire information on a wide range of potential risk factors including sources of indoor air pollution, SES, and family medical history.
Subjects were screened using blood samples, lung function tests, and questionnaires.
Lead author Bernd Lamprecht, a pulmonologist at Paracelsus Medical University in Salzburg, says this is the first population-based study to evaluate COPD on the basis of measured postbronchodilator lung function, in combination with questionnaire data on occupational exposure.
The selection of the 57 children (33 boys and 24 girls) from the larger study in November 2001 was based on the results from the lung function tests and a questionnaire answered by the parents.
Response was assessed by lung function tests and symptom questionnaires.
We will perform a baseline assessment including detailed patient history, questionnaires, lung function, history of exacerbations, measurement of exercise capacity and blood sampling.
[ 14] On an annual basis the CT intervention group was offered a CT scan and completed annual lung function tests together with questionnaires on smoking habits, health status, psychosocial factors, and quality of life issues.
Baseline parameters include socio-demographic and anthropometric parameters, MRC dyspnoea scale, HADS, SGRQ, the self-efficacy questionnaire and lung function values.
Correlations between the scores of the PAQLQ, of an asthma control instrument, of a general health questionnaire and lung function indexes were moderate.
