Most studies on pediatric asthma rely on the report of "wheezing" in questionnaires. Here is what wheezing sounds like (click to play the embedded video):
This study from Portugal investigated the understanding of this term by 400 parents with, what else, a questionnaire.
The term "wheezing" was not recognized by 34% of parents, more frequently those who:
- were younger (OR 0.4 per 10-year increment)
- had lower education (OR 3.3)
- whose children had no history of respiratory disease (OR 4.6)
31% of parents familiar with "wheezing" either did not identify it as a sound, or did not locate it to the chest. Tactile (40%) and visual (34%) cues to identify "wheezing" were used.
The study suggests the need for more accurate questionnaires and objective measurements to evaluate "wheezing" disorders.
