Mortality from abortion and childbirth. Are the populations comparable?
JAMA
|July 9, 1982
Summary
Legal abortion is significantly safer than childbirth. Adjusted mortality rates reveal women were seven times more likely to die from childbirth than legal abortion between 1972-1978, with this gap widening over time.
Area of Science:
- Reproductive Health
- Medical Statistics
- Public Health
Background:
- Previous mortality comparisons between legal abortion and childbirth have faced criticism.
- Concerns were raised about demographic and clinical differences in study populations.
Purpose of the Study:
- To re-evaluate and standardize mortality rates for legal abortion and childbirth.
- To adjust for pre-existing medical conditions and demographic factors.
Main Methods:
- Standardized mortality rates for legal abortion and childbirth were calculated (1972-1978).
- Independent adjustments were made for pre-existing medical conditions.
- Demographic and health differences between the populations were controlled for.
Main Results:
- Standardization and adjustments widened the disparity in mortality risk.
- Women were approximately seven times more likely to die from childbirth than legal abortion.
- The mortality gap between childbirth and legal abortion increased during the study period.
Conclusions:
- Legal abortion demonstrated a significantly lower mortality risk compared to childbirth.
- Adjusting for health and demographic factors reinforces the safety of legal abortion relative to childbirth.
- Findings highlight the importance of standardized data in understanding reproductive health outcomes.

01:52Regression Toward the Mean
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...
02:57Meiosis vs. Mitosis
Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...

01:22Life Tables
A life table is a statistical tool that summarizes the mortality and survival patterns of a population, providing detailed insights into the likelihood of survival or death across different age intervals within a cohort. By organizing data on survival probabilities and mortality rates, life tables offer a clear snapshot of population dynamics over time. They are extensively used in demography, public health, actuarial science, and ecology to analyze life expectancy, design health interventions,...
01:20Actuarial Approach
The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.

01:20Comparing the Survival Analysis of Two or More Groups
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and Cox...
01:22Applications of Life Tables
Life tables are versatile across various fields, providing a quantitative basis for analyzing mortality and survival rates. Whether used by demographers, actuaries, epidemiologists, or sociologists, life tables offer valuable insights into the dynamics of life and death, facilitating informed decisions in public health, insurance, conservation, and beyond. Their broad applicability highlights the interconnectedness of demographic data with practical outcomes in everyday life and strategic...
