Table 3.
Prevalence of environmental intolerances (EIs) according to EI definitions A–F * used in this study. An individual may have EI to one or more factors and may be included in various definitions A–F. The percentage is calculated from the total n = 680, n (%).
| Definitions of EI | EI Attributed to | ||||
|---|---|---|---|---|---|
| Any of the 12 Environmental Factors | Chemicals **, Molds, or EMFs (Any of the Three) | Chemicals ** | Molds | EMFs | |
| A | 457 (67.2) | 310 (45.6) | 198 (29.1) | 222 (32.6) | 20 (2.9) |
| B | 302 (44.4) | 226 (33.2) | 155 (22.8) | 166 (24.4) | 16 (2.4) |
