Socio-economic inequities in XXXX 's injury rates: has the gradient changed over time?

@entity1 @entity4968 @entity2587 @entity159 @entity130
INTRODUCTION: Changing socio-economic gradients in adult health over time have been documented, but little research has investigated temporal changes in @entity1 health gradients. Childhood hospitalizations for injury have fallen over the last two decades; whether the socio-economic gradient in childhood injury has changed is unknown. METHODS: Population-based hospital discharge data were used to calculate rates of hospitalization for injury from 1986/87 through 2005/06 for all @entity1 under 20 years of age in Manitoba (average yearly number of hospitalizations = 326,357). Information on @entity159 ( @entity159 ) came from area-level census data and was assigned by residential postal codes. Generalized linear models with generalized estimating equations were employed to describe the relation between @entity159 and injury rates and whether this relation changed over time. All-cause @entity130 were examined as well as @entity130 for motor vehicle collisions (MVCs), other @entity130 , self-inflicted @entity130 , assault, @entity4968 , @entity130 caused by machinery, @entity2587 and falls. RESULTS: Injury hospitalizations for @entity1 decreased steadily over the study period, from 1.07% to 0.51%. @entity159 significantly predicted @entity130 (p < 0.0001), @entity1 with lower @entity159 showing higher rates. A significant @entity159 by year interaction (p < 0.0001) indicated that the @entity159 gradient for @entity130 increased over time. Analysis by @entity130 found a significant @entity159 by year interaction for MVCs, self-inflicted @entity130 and falls; for MVCs and self-inflicted @entity130 the pattern (increasing @entity159 gradient) was similar to that of hospitalization for all-cause injury. The pattern for falls was inconsistent. CONCLUSION: Despite the overall drop in @entity130 over time, the @entity159 gradient in hospitalized injury rates has increased.
