New York, Dec 14, 2017: Pregnant women’s exposure to non-ionising radiation from smartphones, Bluetooth devices and laptops may double the risk of miscarriage, a study has showed.
Non-ionising radiation — radiation that produces enough energy to move around atoms in a molecule, but not enough to remove electrons completely — from magnetic fields is produced when electric devices are in use and electricity is flowing.
It can be generated by a number of environmental sources, including electric appliances, power lines and transformers, wireless devices and wireless networks.
While the health hazards from ionising radiation are well-established and include radiation sickness, cancer and genetic damage, the evidence of health risks to humans from non-ionising radiation remains limited, said De-Kun Li, a reproductive and perinatal epidemiologist at the Kaiser Permanente — a US-based health care firm.
For the study, published in the journal Scientific Reports, the team asked for 913 pregnant women over age 18 to wear a small (a bit larger than a deck of cards) magnetic-field monitoring device for 24 hours.
After controlling for multiple other factors, women who were exposed to higher magnetic fields levels had 2.72 times the risk of miscarriage than those with lower magnetic fields exposure.
The increased risk of miscarriage associated with high magnetic fields was consistently observed regardless of the sources of high magnetic fields. The association was much stronger if magnetic fields was measured on a typical day of participants’ pregnancies.
The finding also demonstrated that accurate measurement of magnetic field exposure is vital for examining magnetic field health effects.
“This study provides evidence from a human population that magnetic field non-ionising radiation could have adverse biological impacts on human health,” Li noted.
“We hope that the finding from this study will stimulate much-needed additional studies into the potential environmental hazards to human health, including the health of pregnant women,” he said. (IANS)
In Caracas’s main maternity hospital the blood banks and medicine cabinets are empty, the power and water regularly cut out — and women and girls are dying needlessly, according to one of the few remaining doctors, Luisangela Correa.
The surgeon is one of only three left at the Concepcion Palacios hospital in the Venezuelan capital, where the lifts and most toilets are closed and there are no bandages, sterilizers or X-ray services.
“We are like trapped, kept hostage by this situation … hope is what keeps us here,” Correa, 45, told the Thomson Reuters Foundation.
“If we haven’t left the hospital, it’s because we hope that things will improve.”
One in four have left
Millions of Venezuelans have fled the country to escape an economic and political crisis that has left about seven million — one in four — in need of humanitarian aid, according to the United Nations.
Its human rights chief Michelle Bachelet said last week after a three-day mission in March to the troubled South American country that Venezuela’s healthcare sector was in “critical condition.”
A lack of basic medicine and equipment was “causing preventable deaths,” she said — something Correa is witnessing at first hand.
Infection rates at the maternity hospital are high because cleaners do not have disinfectants to wash away bacteria and there are no sterilizers for doctors to clean their equipment, she said.
“Currently, maternity is a risk for Venezuelan women, as it is for babies … many give birth at home, in the street,” Correa said.
“And there are no blood banks. Any complications from heavy bleeding is a very big risk of death for a patient.”
Correa, the U.N. and women’s rights groups all said unsanitary hospital conditions along with food and medical shortages had led to a rise in maternal mortality rates.
U.N. findings disputed
The Venezuelan government disputed the findings of the U.N. report and said in a written response that maternal mortality rates had decreased by nearly 14% between 2016 and 2018.
Venezuela’s national healthcare system, once considered a model for Latin America, is now plagued by shortages of imported drugs and thousands of doctors and nurses no longer show up for work, their salaries ravaged by inflation.
Venezuelan President Nicolas Maduro has said there is little need for humanitarian aid, blaming U.S. sanctions for the oil-rich country’s economic problems.
The United States imposed tough sanctions on Venezuela’s oil industry in January in an effort to oust Maduro in favor of opposition leader Juan Guaido, who is recognized as Venezuela’s rightful leader by more than 50 governments.
CEPAZ, a coalition of women’s rights groups, has said Venezuela’s maternal mortality rates have increased by 65% from 2013 to 2016, with nearly 800 women dying.
Bachelet’s report cited a national survey that showed 1,557 people died due to lack of supplies in hospitals between November 2018 and February 2019.
Correa said she was seeing more pregnant teenage girls seeking care because they cannot find or afford contraception and do not receive sex education in schools.
According to the U.N. report, teenage pregnancies have risen by 65% since 2015, and several cities in Venezuela face a “100% shortage” of all types of contraception.
Strict abortion law
Due to Venezuela’s strict abortion law, which only allows the procedure under limited circumstances, some women and girls resort to unsafe abortions.
This has contributed to a rise in preventable maternal mortality, with about 20% of maternal deaths reportedly linked to unsafe abortions, the U.N. said in its report.
Correa says she is determined to continue to speak out about the dire conditions in public hospitals and help women in need. “The only thing we have are the outcries and hope that this will change,” she said. “My people, my country need me at this moment.” (VOA)
