Shuttering coal- and oil-fired power plants lowers the rate of preterm births in neighboring communities and improves fertility, according to two new University of California, Berkeley, studies.
The researchers compared preterm births and fertility before and after eight power plants in California closed between 2001 and 2011, including San Francisco’s Hunters Point plant in 2006.
Overall, the percentage of preterm births – babies born before 37 weeks of gestation – dropped from 7 percent in a year-long period before plant closure to 5.1 percent for the year after shutdown. Rates for non-Hispanic African-American and Asian women dropped even more: from 14.4 percent to 11.3 percent.
Preterm births, which can often result in babies spending time in a neonatal intensive care unit, contributes to infant mortality and can cause health problems later in life. The World Health Organization estimates that the cost of preterm births, defined as births between 32 and 37 weeks of gestation, accounts for some $2 billion in healthcare costs worldwide.
