[Effect of various weather parameters on the incidence of inpatient treated children with stenosing laryngotracheitis (pseudocroup)].
A total of 1470 hospitalized children with croup in the cities of Bochum and Herne were examined over a period of 19 years, with the aim of checking whether there was any relationship between croup incidence and changes in different weather parameters such as temperature, air pressure, absolute and relative air humidity, and wind speed. The incidence of croup was seasonal, being higher in the months of January, February, and March and from September to December. Statistical evaluation by discriminant analysis, t-test and chi 2-test showed a significant correlation (alpha greater than or equal to 0.95) between croup incidence and individual weather parameters in some months. The results seem to indicate a higher frequency of croup after decreases in temperature and influx of dry air masses (decreases in absolute humidity). In some months an increased incidence of hospitalized children with croup was observed after decreases in air pressure and during weather with extremely high (w greater than 4.5) or low (w less than 1.5) wind speed. In summary, no clear and consistent relationship between incidence of croup and particular weather parameters could be found.
