Over the past few days, a whole bunch of news articles have claimed that WiFi and cellphone signals increase a pregnant woman's miscarriage risk. Some examples:
"WiFi and mobile phones could increase pregnant women's risk of miscarriage, study claims", The Mirror (2017-12-15):
Results reveal pregnant women with the highest MF-radiation exposure have a 48 percent greater risk of miscarrying than those with the lowest exposure.
"Wi-fi and cellphones increase pregnant women's risk of a miscarriage by nearly 50%, study reveals", Daily Mail (2017-12-14):
Magnetic field (MF) non-ionizing radiation is also given off by power lines
Pregnant women exposed to the highest levels are 48% more likely to miscarry
Some 24.2% of such women miscarry versus 10.4% with the lowest exposure
MF radiation, which everyone is exposed to, has previously been linked to cancer
Miscarriages affect between 15 and 20 percent of pregnancies in the US
The women were asked to disclose if they had previously had a miscarriage, smoked, drank alcohol and had suffered any fever or infection - all factors that can increase the risk of miscarriage.
Of the 913 women who participated, those who were exposed to the lowest amount of radiation were 10.4 per cent more likely to suffer a miscarriage.
Women who were exposed to higher levels were 24.2 per cent more likely to have a miscarriage.
All of these articles claim research done by the Kaiser Permanente Division of Research in Oakland, California, and published in the journal Scientific Reports.
I have tried my best to track down the paper in question to establish if it really has some actual basis. Additionally, I have tried to find out if this research company and the journal they published in are reputable. I haven't had much success.
Do these claims have any proper, reputable basis?
