Detroit had the highest preterm birth rate of any U.S. city at over 15% last year, according to a new report from March of Dimes. There are also glaring racial differences in the maternal mortality rate nationally. Today on The Metro, several health care and childcare professionals join the show to discuss the risks facing expectant mothers and what can be done to alleviate them. Plus, the founders of Pingree Detroit — a worker-owned company that reclaims discarded leather from the automotive industry — join the show to talk about all that goes into their business.
