Why This Indicator Matters

Babies born before 37 weeks are more likely to have health problems and often need to stay in the hospital longer than babies born later. There can be a greater likelihood of intellectual delays and behavioral health issues such as ADHD or Autism and neurological issues such as cerebral palsy. Finding and treating health problems as early as possible — and preventing premature birth overall — can help babies lead longer, healthier lives. March of Dimes- preterm birth health issues

In Maine, the percent of preterm births has been on an upward trend since 2012. This trend of recent increases mirrors national data.  The 2021 rate in Maine was 9.3% and in 2020 it was 8.9% and in 2017 just 8.1%.

For 2021, the counties with the highest rate of preterm births as a percentage of all births were: Waldo (12.0%), Lincoln (11.4%) and Penobscot (11.4%) while the counties with rates of preterm births under 8.0% were: Cumberland and Knox, both at 7.9%.
