Highly exposed mothers had only 23.5% male births, a statistically significant altered gender ratio with dose-response pattern, and radiation was linked to low birthweight only in male newborns.

Plain English Summary

Summary written for general audiences

Case groups were spontaneous abortions, low birth-weight prematurity, and stillbirth or death within one year, and exposure was assessed by telephone interviews. Highly exposed mothers had only 23.5% male births, a statistically significantly altered gender ratio showing a dose-response pattern. High-frequency electromagnetic radiation was associated with low birthweight, but only for male newborns.

Why This Matters

Cases and referents were sampled from a cohort of pregnancies of members of the Union of Danish Physiotherapists through linkage of the union file with national medical registers. As referents to the 270 cases, 316 pregnancies were randomly sampled.

Study Details

The aim of this case-referent study was to investigate reproductive hazards other than congenital malformations after exposure to high-frequency electromagnetic radiation.

The other outcomes were not statistically significantly associated with exposure to high-frequency electromagnetic radiation.
