Percent of pregnancies ending with spontaneous abortion Abortion incidence ratio
Review the default percent of pregnancies ending with spontaneous abortion and the abortion incidence ratio, and make any changes necessary. If you have FamPlan active, you may click on "Calculate abortion ratio based on FamPlan outputs" if you would like the abortion ratio to be calculated from FamPlan inputs such as method mix and proximate determinants of fertility.
Percent of pregnancies ending with spontaneous abortion
•Definition: The spontaneous end of a pregnancy at a stage where the embryo or fetus is incapable of surviving independently, generally defined in humans as prior to 20 weeks of gestation. Spontaneous abortions are not easily measured and are thus assumed to average 13% of pregnancies in all countries.
•Notes:
•Definition: The abortion incidence is expressed as a ratio of abortions per 100 live births.
•Default data source: Sedgh G, Bearak J, Singh S, et al. Abortion incidence between 1990 and 2014: global, regional, and subregional levels and trends. Lancet 2016; 388: 16-22. http://www.ncbi.nlm.nih.gov/pubmed/27179755. (Unpublished calculations based on abortion incidence rates in paper.)
•Notes: Values are by subregion. |
