In terms of maternal injury, what is the ranking of mechanisms from most common to least common?

The most common mechanisms of maternal injury begin with motor vehicle collisions, as these incidents are a significant cause of trauma among pregnant women due to their frequency in everyday life. With the increase in mobility and driving during pregnancy, the risk associated with motor vehicle accidents remains prevalent.

Following motor vehicle collisions, falls rank as the second most common mechanism of injury. Pregnant women are at an increased risk of falling due to physical changes such as a shift in center of gravity and balance issues as the pregnancy progresses.

Violence, while a serious concern, particularly in certain populations, generally occurs less frequently than the other two mechanisms listed. It contributes to maternal injury but does not occur as often compared to accidents and falls in general statistical reporting.

Understanding this hierarchy helps emphasize the significance of roadway safety and awareness of environmental hazards for pregnant women. Thus, the ranking from most common to least common in terms of maternal injury is accurately captured by the selection of motor vehicle collisions followed by falls and then violence.
