Proposed association between airborne pollen and pediatric asthma emergency room visits in the Caribbean Island of Trinidad and Tobago West Indies
There are a number of possible links between airborne pollen and respiratory disease that remain underappreciated by both the scientific community and health care providers within the Latin American and Caribbean region. A few regional studies have assimilated some preliminary information on this association, and most recently research on interactions between airborne pollen and pediatric asthma on the Caribbean island of Trinidad has shown critical areas that require further investigation. Pollen samples were collected over a 2-year period using a Burkard 7 Day Recording Volumetric Spore Sampler. Corresponding pediatric asthma data were recorded at a nearby medical hospital. Results indicated that the wet season showed higher pollen concentrations (82 pollen per cubic meter/day) than the dry season (53 pollen per cubic meter/day), and several pollen taxa were observed. An association between airborne pollen concentrations and pediatric asthma emergency room visits was suggested incorporating a threshold and lag period.
