The \u201cmaternal age-specific infant mortality rate\u201d is the mortality rate of infants born to women in a given maternal age category; for example, the mortality rate of infants born to women who were 20-24 years old.<\/p>\n<hr \/>\n<p><strong>Q<\/strong>: Was there a specific finding in the data that surprised you from this report?<\/p>\n<p><em><strong>AD<\/strong><\/em>: It was somewhat surprising that changes in maternal age distribution mattered little or not at all for the mortality trends for infants born to non-Hispanic black and Hispanic women given the significant changes in the maternal age distribution for both groups during the study period.<\/p>\n<hr \/>\n<p><strong>Q<\/strong>: How did you obtain this data for this report?<\/p>\n<p><em><strong>AD<\/strong><\/em>: The data are from the National Vital Statistics System (NVSS); we used natality data sets and infant mortality data sets from 2000-2017. Natality data sets are comprised of information from all birth certificates in a given year; infant mortality data sets are comprised of information from all death certificates to persons under one year of age in a given year.<\/p>\n<hr \/>\n<p><strong>Q<\/strong>: What is the take home message for this report?<\/p>\n<p><em><strong>AD<\/strong><\/em>: Changes in the age distribution of women giving birth accounted for about one-third of the decline in infant mortality rates from 2000 through 2017 while declines in maternal age-specific mortality rates accounted for about two-thirds of this decline.
