This cross-sectional study aims to assess the level of awareness, knowledge, and preventive behaviors regarding air quality and air pollution among parents of children with physician-diagnosed allergic respiratory diseases (asthma and/or allergic rhinitis). The survey will evaluate parents' understanding of air pollution effects, sources, and protective measures, as well as sociodemographic and clinical correlates influencing awareness.

Inclusion Criteria:

• Parent or primary caregiver of a child aged 2-18 years
• Child has a physician-diagnosed asthma and/or allergic rhinitis
• Able to read and understand Turkish
• Provides informed consent

Exclusion Criteria:

• Parents of children with other chronic respiratory or systemic diseases
• Parents who are healthcare professionals (to avoid bias)
• Incomplete survey responses

The study population consists of parents or primary caregivers of children aged 2 to 18 years who have been clinically diagnosed with allergic airway diseases, specifically asthma and/or allergic rhinitis, by a pediatric allergy specialist.

Participants will be recruited from the outpatient Pediatric Allergy Clinic of a tertiary healthcare center.

All participants must be able to read and understand Turkish and voluntarily provide written informed consent.

The survey targets approximately 500 parents, representing diverse educational and socioeconomic backgrounds, to evaluate knowledge, awareness, and behaviors related to air quality and pollution.

Individual participant data (IPD) will not be shared publicly because the dataset contains potentially identifiable information collected from a limited number of participants at a single center.

Only aggregated, de-identified summary data will be included in publications and presentations.

The study protocol and statistical analysis plan may be shared upon reasonable request from qualified researchers, following approval by the principal investigator and the institutional ethics committee.
