Associations of Maternal Cell-Phone Use During Pregnancy With Pregnancy Duration and Fetal Growth in 4 Birth Cohorts
Authors not listed · 2019
The intermediate cell-phone use group had a higher risk of lower gestational age, with exposure-response relationships for shorter pregnancy duration and preterm birth, but no association with fetal growth or birth weight.
Plain English Summary
Researchers used data from 55,507 pregnant women across four birth cohorts in Denmark, the Netherlands, Spain, and South Korea to examine associations between maternal cell-phone use and pregnancy outcomes. Exposure was categorized based on self-reported daily call frequency into none, low, intermediate, or high groups. The intermediate exposure group showed a higher risk of lower gestational age (hazard ratio 1.04, 95% CI 1.01–1.07), and exposure-response trends were seen for shorter pregnancy duration and preterm birth. No associations were found with fetal growth or birth weight measures.
Why This Matters
The study assessed pregnancy duration, fetal growth, and birth weight variables, and combined cohort-specific estimates through meta-analysis. The authors cautioned that the observed associations might reflect stress or residual confounding and not a direct effect of cell-phone exposure.
