摘要

Background

The present study investigated the association between exposure to electromagnetic waves from widely used devices and pregnancy and birth outcomes among women in Yazd City.

Methods

This study was conducted on a total of 1,666 participants enrolled in the Yazd Mother and Child Cohort Center between 2015 and 2019. Cell phones, cordless phones, and Wi-Fi instruments were considered electromagnetic wave sources. Pregnancy and birth outcomes examined in this study include miscarriage, preterm labor, abnormal birth weight, and deviations in newborn height and head circumference. SPSS version 24 and R-studio version 4.3.1 software were used for statistical analysis.

Results

The current study revealed that 41 (2.5%) mothers had miscarriage and 174 (10.4%) mothers experienced preterm labor. Furthermore, 181 (10.9%) infants with abnormal birth weights, 117 (7%) infants with abnormal height, and 124 (7.4%) infants with abnormal head circumference were observed in this study. Individuals with longer cell phones call duration during pregnancy had higher risk of miscarriage (p < 0.001, RR (95% CI), 1.0061(1.003–1.0093)), abnormal birth weight (p = 0.002, RR (95% CI), 1.0012 (1.0004–1.002)) and height (p = 0.003, RR (95% CI), 1.0014 (1.0004–1.0023)) in comparison with those with lower cell phone call duration in this period.

Conclusion

The findings of the study revealed that an increase in exposure to cell phones during pregnancy can increase the risk of pregnancy and birth outcomes, namely miscarriage, abnormal weight and height of the infant. Furthermore, cordless phone conversations could increase the risk of abnormal weight in newborns.
