Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

• Level of Parental Knowledge and Awareness About Air Quality

  The primary outcome is the overall score obtained from the Air Quality Knowledge and Behavior Questionnaire, reflecting parents' knowledge and awareness regarding air quality and air pollution. The composite score will be derived from the 5 knowledge and 10 awareness items, each rated on a Likert scale (e.g., 1 = strongly disagree to 5 = strongly agree). Higher total scores indicate greater knowledge and awareness of air pollution, its sources, and its health effects.

Study Arms (1)

Parents of Children with Allergic Airway Diseases

This cohort includes parents or primary caregivers of children aged 2-18 years who have been clinically diagnosed with allergic airway diseases (asthma and/or allergic rhinitis) by a pediatric allergy specialist. Participants will complete a structured questionnaire assessing their awareness, knowledge, and preventive behaviors regarding air pollution and air quality.

Behavioral: Air Quality Knowledge Questionnaire

Interventions

Air Quality Knowledge Questionnaire BEHAVIORAL

A structured, self-administered questionnaire on air quality and pollution will be provided to all participants. The survey consists of a total of 23 main items and an additional demographic information section. The demographic section collects data on parent's age, gender, education level, occupation, and the child's age, gender, diagnosis (asthma and/or allergic rhinitis), and disease duration. The main questionnaire includes: * 5 items assessing knowledge of air pollution and air quality concepts; * 10 items measuring awareness of air pollution sources, health impacts, and environmental conditions; * 8 items evaluating attitudes and protective behaviors toward air pollution (e.g., monitoring air quality index, modifying outdoor activities, using indoor air filters). Responses are based on a Likert-type scale. The tool is designed to quantify parental understanding, awareness, and preventive practices related to air quality in the context of childhood allergic airway diseases.

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.
