CDC also collaborated with organizations to develop the Sudden Unexpected Infant Death (SUID) Case Registry, which seeks to improve population-based SUID surveillance in grantee states.Reports are generated from these systems on a routine ongoing basis.DRH also monitors teen pregnancy and the number and characteristics of women obtaining legal induced abortions in the United States.
DRH researchers sometimes analyze secondary data on such topics as ectopic pregnancy and hysterectomy.
In 2012, 699,202 legal induced abortions were reported to CDC from 49 reporting areas.
The abortion rate for 2012 was 13.2 abortions per 1,000 women aged 15–44 years, and the abortion ratio was 210 abortions per 1,000 live births.
Compared with 2011, the total number and ratio of reported abortions for 2012 decreased 4%, and the abortion rate decreased 5%.
Additionally, from 2003 to 2012, the number, rate, and ratio of reported abortions decreased 17%, 18%, and 14%, respectively.
Given the large decreases in the total number, rate, and ratio of reported abortions from 2011 to 2012, in combination with decreases that occurred during 2008–2011, all three measures reached historic lows.
Women in their twenties accounted for the majority of abortions in 2012 and throughout the period of analysis.
The majority of abortions in 2012 took place early in gestation: 91.4% of abortions were performed at ≤13 weeks’ gestation; a smaller number of abortions (7.2%) were performed at 14–20 weeks’ gestation, and even fewer (1.3%) were performed at ≥21 weeks’ gestation.
Public health surveillance is the ongoing systematic collection, analysis, and interpretation of outcome-specific data for use in public health practice.
