Summary
Legal induced abortion numbers and rates decreased in 2007, reversing a prior increase. Data from the Centers for Disease Control and Prevention (CDC) show trends in abortion surveillance to inform public health efforts.
Area of Science:
- Public Health Surveillance
- Reproductive Health
- Demography
Background:
- The Centers for Disease Control and Prevention (CDC) has monitored legal induced abortions in the United States since 1969.
- Surveillance data are crucial for understanding trends and characteristics of women obtaining abortions.
Purpose of the Study:
- To document the number and characteristics of women obtaining legal induced abortions in the United States for 2007.
- To analyze trends in abortion rates and ratios from 1998 to 2007.
Main Methods:
- Abortion data were collected from 49 reporting areas in the United States for 2007.
- Trend analysis utilized data from 45 areas reporting consistently from 1998 to 2007.
- Abortion rates and ratios were calculated using census and natality data.
Main Results:
- In 2007, 810,582 abortions were reported by the 45 consistent reporting areas, with a rate of 16.0 per 1,000 women and a ratio of 231 per 1,000 live births.
- Abortion numbers, rates, and ratios decreased by 2-3% from 2006 to 2007 and by 6-14% from 1998 to 2007.
- Women aged 20-29 accounted for the majority of abortions, while abortion rates increased for women aged 35+ and decreased for younger age groups.
Conclusions:
- The decrease in reported abortions from 2006-2007 reversed a prior increase, though numbers remained higher than in 2005.
- Legal induced abortion-related deaths remain rare.
- Continued abortion surveillance provides essential data for policymakers to guide and evaluate unintended pregnancy prevention efforts.

01:19Pharmacovigilance
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

01:26Principles of Disease Surveillance
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...
