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 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
What the Data Shows
Approximately 10.4% of all births in the US 2022 were premature compared to 9.5% in Maine.
In both United States and in Maine, preterm births spiked in 2021, with the highest rates in 15 years and 2022 is almost as high. In the United States for 2020-2022, the preterm birth rate among black women is 14.6%, substantially higher than the rate among all other women. March of Dimes Preterm Birth Rates
In Maine, the percent of preterm births has been on a upward trend since 2012. This trend of recent increases mirrors national data. The 2022 rate in Maine was 9.5%, higher than 9.3% the previous year and 8.9% in 2020 and in 2017 was just 8.1%.
For 2022, the counties with the highest rate of preterm births as a percentage of all births were: Franklin (12.2%), Androscoggin 11.8% and Piscataquis 11.5% while the counties with rates of preterm births under 8.0% were: Hancock, 7.0%, Somerset 7.4%, and Sagadahoc, 7.9%.
