| Zusammenfassung |
| Statistically significant correlations between increase of asthma attacks in
children and elevated concentrations of particulate matter of diameter 10
microns and less (PM10) were determined for metropolitan Phoenix,
Arizona. Interpolated concentrations from a five-site network provided
spatial distribution of PM10 that was mapped onto census tracts with
population health records. The case-crossover statistical method was applied
to determine the relationship between PM10 concentration and asthma
attacks. For children ages 5–17, a significant relationship was discovered
between the two, while children ages 0–4 exhibited virtually no
relationship. The risk of adverse health effects was expressed as a function
of the change from the 25th to 75th percentiles of mean level
PM10 (36 μg m−3). This increase in concentration was
associated with a 12.6% (95% CI: 5.8%, 19.4%) increase in the
log odds of asthma attacks among children ages 5–17. Neither gender nor
other demographic variables were significant. The results are being used to
develop an asthma early warning system for the study area. |
