Aim of study (acc. to author)

A case-control study was conducted in Iran to determine the effects of exposure to mobile phones during pregnancy and the risk of spontaneous abortion.

Endpoint/type of risk estimation

Type of risk estimation:




Case group

Control group

Eligible 292 308
Evaluable 226 246
Statistical analysis method: (adjustment: )

Conclusion (acc. to author)

All data pertaining to mobile phone use such as average calling time per day, the location of the mobile phones when not in use, use of phones for other applications, SAR and the average of the calculated effective SAR, except the use of hands-free devices were different between the case group and the control group. A significant association between the calculated effective SAR and the risk of spontaneous abortions was observed (OR 1.11; CI 1.07-1.16).
The results suggest that use of mobile phones could be related to the early spontaneous abortions.

Limitations (acc. to author)

The results should be interpreted with cautions due to study design, further not considered risk factors for spontaneous abortion and exposure assessment.
