  39. Birth Outcomes for Selected Communities

  40. Highest Infant Mortality Rates Among the 30 Largest Communities1 Massachusetts: 2005 1Selected among the 30 Massachusetts communities with the largest populations. IMR = infant deaths per 1,000 live births. 2A Confidence Interval for a population parameter is a range in which you are 95% certain that the true population estimate is within. It is a function of variability and the number of events. * Statistically Significant (p ≤.05)

  45. Summary – Successes • Many Massachusetts perinatal health indicators are better than those of the U.S. • Continued decline in teen birth rates • Fewer women are smoking during pregnancy • 4 out of 5 women receive adequate prenatal care

  46. Summary–Challenges • Trends that must be closely monitored: • Low birthweight & preterm births • Multiple births • C-Section deliveries • Decline in overall number of births • Slight up-tick in IMR from 2004 and increase in selected communities

  47. Disparities Persist by Race, Geography, and SES • Black non-Hispanic IMR is twice as high as the white non-Hispanic IMR • Hispanic teen birth rate is almost 6 times that for white non-Hispanics • Cambodian, Central American, and African mothers are less likely to receive prenatal care in their first trimester • Low birthweight rates in Brockton, Revere, and New Bedford are at least 2 times the statewide rate • Less educated mothers have worse birth outcomes than more educated mothers
