Residential exposure to 50 Hz magnetic fields and the association with miscarriage risk: a 2-year prospective cohort study.
Published in: PLoS One 2013; 8 (12): e82113
Aim of study (acc. to author)
Endpoint/type of risk estimation
Type of risk estimation:
(relative risk (RR))
magnetic field strength measurements at the front door of the houses, in the alleys in front of the subjects' houses, and at public clubs for entertainment on days when the electric power supply loads were relatively high Exposure groups
Reference group 1
unexposed, magnetic field strength: < 0.1 µT
exposed, magnetic field strength: ≥ 0.1 µT
group A, magnetic field strength: 0.1 - < 0.4µT
group B, magnetic field strength: 0.4 µT - 4.26 µT
pregnant women from the Chinese Han population
May 2010 - May 2012
China (2 towns in the Pearl-River Delta)
pregnant women with a history of thalassemia, sicklemia, G-6-PD deficiency, thyrotoxicosis, diabetes; living in the area less than 6 months or migrating
Statistical analysis method:
Cox proportional regressions analysis
