The relationship between weight indices and injuries and mortalities caused by the motor vehicle accidents: a systematic review and meta-analysis

Background: the relationship between weight indices and injuries and mortality in motor vehicleaccidents is unknown. systematic review studies addressing the collection and analysis of therelationship in investigations are very limited. the purpose of this systematic review is to determinethe relationship between bmi, obesity and overweight with mortality and injuries and their severityand vulnerable organs after the motor vehicle accident.methods: the databases (medline/pubmed, embase, web of science, etc) were searched forrelevant abstracts using certain keywords. of all the articles, similar ones were removedconsidering different filters. the collected data were entered into the stata se v 13.1. theheterogeneity of the data was analyzed using i2 statistics. in addition, the estimates of the studywere done based on the age group (children and adults) and the impact of obesity on differentregions of the body.results: a direct relationship was observed between the overall bmi and the degrees of injuries(ci=0.503-1.139), and mortality due to motor vehicle accident (ci=1.267-1.471). a positiverelationship was found between obesity and ais+2 (ci=0.653-1.426), and ais+3 (ci=1.184-1.741), and iss (ci=1.086-1.589).also, a negative relationship between overweight and injuries rates, and a direct relationshipbetween overweight and mortality (ci=0.979-1.167), and injuries with index of ais+2(ci=1.178-0.768) and ais+3 (ci=0.48-2.186) were found.conclusions: the prediction of injury, mortality and severity of injuries in the motor vehicleaccident by the variable of obesity and overweight determines the need to design preventionprograms for this vulnerable group at all levels.
