The purpose of this study was to compare the age and sex trends of motor vehicle collision injuries between a nationally representative self-report survey and official police motor vehicle collision report data. To do this, population-based estimates of motor vehicle collision injuries were established using data from the National Population Health Survey (NPHS), a prospective, population-based, longitudinal survey that was compared to Transport Canada's official motor vehicle collision report statistics.
Aggregated mean data (1994-1996) were compared for seven age groups (15-19, 20-24, 25-34, 35-44, 45-54, 55-64, and 65+) from both data sets.
No significant differences were found between males' and females' MVC injuries for any age category in the NPHS. A comparison of the NPHS and Transport Canada data found two small (significant) within-sex differences between the data sets, but overall, the analysis largely revealed similar trends for self-reported injury for all age categories and sex.
The results indicate that the incidence of injuries based on self-report data in a nationally representative sample is similar to official sources of reporting and are thus a valid indicator or motor vehicle collision injury incidence. The results also confirm that injury trends differ from fatality trends.
本研究旨在比较具有全国代表性的自我报告调查与警方机动车碰撞事故官方报告数据中机动车碰撞伤害的年龄和性别趋势。为此，利用全国人口健康调查（NPHS）的数据建立了基于人群的机动车碰撞伤害估计数，该调查是一项前瞻性、基于人群的纵向调查，并与加拿大运输部的官方机动车碰撞事故报告统计数据进行了比较。
对两个数据集的七个年龄组（15 - 19岁、20 - 24岁、25 - 34岁、35 - 44岁、45 - 54岁、55 - 64岁和65岁以上）的汇总平均数据（1994 - 1996年）进行了比较。
在全国人口健康调查中，任何年龄组的男性和女性机动车碰撞伤害均未发现显著差异。对全国人口健康调查和加拿大运输部数据的比较发现，两个数据集中存在两个较小的（显著的）性别内差异，但总体而言，分析在很大程度上揭示了所有年龄组和性别的自我报告伤害的相似趋势。
结果表明，在具有全国代表性的样本中，基于自我报告数据的伤害发生率与官方报告来源相似，因此是机动车碰撞伤害发生率的有效指标。结果还证实，伤害趋势与死亡趋势不同。
