Soybean unloading in the harbor of Barcelona, Spain, has been associated with large increases in the numbers of asthma patients treated in emergency departments between 1981 and 1987.
In this study, the association between asthma and soybean unloading in two other Spanish cities, Valencia and A Coruna, was assessed.
Asthma admissions were retrospectively identified for the period 1993-1995, and harbor activities were investigated in each location.
Two approaches were used to assess the association between asthma and soybean unloading : One used unusual asthma days (days with an unusually high number of emergency room asthma visits) as an effect measure, and the other estimated the relative increase in the daily number of emergency room visits by autoregressive Poisson regression, adjusted for meteorologic variables, seasonality, and influenza incidence.
No association between unusual asthma days and soya unloading was observed in either Valencia or A Coruna, except for one particular dock in Valencia.
When the association between unloaded products and the daily number of emergency asthma visits was studied, a statistically significant association was observed for unloading of soya husk (relative risk=1.50,95% confidence interval 1.16-1.94) and soybeans (relative risk=1.31,95% confidence interval 1.08-1.59) in A Coruna, In Valencia, a statistical association was found only for the unloading of soybeans at two particular docks.
