Interactive effects of allergens and air pollution on respiratory health: A systematic review.

ABSTRACT:

Background

Studies have demonstrated an adverse role of outdoor allergens on respiratory symptoms. It is unknown whether this effect is independent or synergistic of outdoor air pollutants.

Methods

We systematically reviewed all epidemiological studies that examined interaction effects between counts of outdoor airborne allergens (pollen, fungal spores) and air pollutants, on any respiratory health outcome in children and adults.

Each study was summarized qualitatively and assessed for quality and risk of bias (International Prospective Register for Systematic Reviews, registration number CRD42020162571).

Results

Thirty-five studies were identified (15 timeseries, eight case-crossovers, 11 panels and one cohort stu
