Résumé
Seat belt use during motor vehicle collisions (MVCs) has been shown to alter adults' intra-abdominal injury patterns, although the effect of seat belt use in pregnant women is unclear. The objective of this study was to determine the impact of seat belt use in pregnancy on injuries and outcomes after MVCs. Patients injured by MVCs were identified from the National Trauma Data Bank (2007-2014). The exclusion criteria were transfer from an outside hospital, male or unspecified sex, missing restraint data, and nonchildbearing age. Demographics, clinical/injury data, pregnancy status, seat belt use, and outcomes were collected. Study groups were dichotomized by pregnancy status with subgroup analysis by seat belt use. Univariate/multivariate analyses compared outcomes and determined predictors of seat belt use. After exclusions, 162,964 women were included, of which 680 (<1%) were pregnant. Intra-abdominal injuries during pregnancy did not vary according to seat belt use (P > 0.05). Unrestrained pregnant women were more injured (Injury Severity Score: 13 versus 7, P < 0.001), more likely to need emergent operation (14% versus 10%, P < 0.001), and had a longer hospital stay (6 versus 4 d, P = 0.012) than restrained counterparts. On multivariate analysis among pregnant women, seat belt use was associated with age ≥25 y (odds ratio: 2.033, P = 0.001). The lack of restraint use was associated with the position in the passenger seat (odds ratio: 0.521, P = 0.001). Seat belt use in pregnancy does not alter abdominal injury patterns but is associated with lower injury severity, reduced need for emergent surgery, and shortened hospital stay. Public health interventions emphasizing the importance of seat belts could be focused on younger patients and vehicle passengers to reach the high-risk pregnant subset.

BACKGROUND
Seat belt use during motor vehicle collisions (MVCs) has been shown to alter adults' intra-abdominal injury patterns, although the effect of seat belt use in pregnant women is unclear. The objective of this study was to determine the impact of seat belt use in pregnancy on injuries and outcomes after MVCs.
METHODS
Patients injured by MVCs were identified from the National Trauma Data Bank (2007-2014). The exclusion criteria were transfer from an outside hospital, male or unspecified sex, missing restraint data, and nonchildbearing age. Demographics, clinical/injury data, pregnancy status, seat belt use, and outcomes were collected. Study groups were dichotomized by pregnancy status with subgroup analysis by seat belt use. Univariate/multivariate analyses compared outcomes and determined predictors of seat belt use.
RESULTS
After exclusions, 162,964 women were included, of which 680 (<1%) were pregnant. Intra-abdominal injuries during pregnancy did not vary according to seat belt use (P > 0.05). Unrestrained pregnant women were more injured (Injury Severity Score: 13 versus 7, P < 0.001), more likely to need emergent operation (14% versus 10%, P < 0.001), and had a longer hospital stay (6 versus 4 d, P = 0.012) than restrained counterparts. On multivariate analysis among pregnant women, seat belt use was associated with age ≥25 y (odds ratio: 2.033, P = 0.001). The lack of restraint use was associated with the position in the passenger seat (odds ratio: 0.521, P = 0.001).
CONCLUSIONS
Seat belt use in pregnancy does not alter abdominal injury patterns but is associated with lower injury severity, reduced need for emergent surgery, and shortened hospital stay. Public health interventions emphasizing the importance of seat belts could be focused on younger patients and vehicle passengers to reach the high-risk pregnant subset.
