Population-based health surveys are increasingly popular sources of data on injury occurrence. Self-reported surveys can yield estimates of the total incidence of non-fatal injuries while simultaneously capturing a rich repository of contextual data that may be informative for exploring determinants of injury risk. Although survey data are rarely recognised as complete, several researchers have expressed concerns about the sensitivity and validity of self-reported injury data, questioning whether captured cases are representative of the population experience of injury, particularly among children and youth. The present study sought to compare the population incidence of paediatric injury estimated from self-reported survey responses to those documented by a complete-capture health service utilisation database among Ontario children.
Injury incidence rates documented from the National Longitudinal Survey of Children and Youth and the National Population Health Survey were compared with those reported in Canada's National Ambulatory Care Reporting System for Ontario youth aged 0-19 years for fiscal year 2002/3, stratified by the child's age and geographical location of residence.
The two self-reported health surveys underestimated the population incidence of injury among Ontario children by at least 49% and 53%, respectively. Systematic errors exist in survey data capture such that injuries in infants and preschoolers (<4 years of age) and urban residents were most likely to be missed by the population health surveys.
Injury incidence estimated through self-report is not representative of the population burden and experience of paediatric injury for Ontario children, and may produce biased estimates of risk when analysed as independent sources of data.
基于人群的健康调查越来越成为伤害发生数据的重要来源。 自我报告的调查可以估计非致命伤害的总发生率，同时获取丰富的背景数据，这些数据可能有助于探索伤害风险的决定因素。 尽管调查数据很少被认为是完整的，但有几位研究人员对自我报告的伤害数据的敏感性和有效性表示担忧，质疑所捕获的病例是否代表了人群的伤害经历，尤其是在儿童和青少年中。 本研究旨在比较从自我报告的调查答复中估计的儿科伤害的人群发生率与安大略省儿童的完整捕获健康服务使用数据库记录的发生率。
比较了 2002/3 财政年度全国儿童纵向调查和全国人口健康调查记录的伤害发生率，以及加拿大安大略省全国非住院护理报告系统报告的 0-19 岁儿童的发生率，并按儿童年龄和居住地的地理位置进行分层。
两项自我报告的健康调查分别低估了安大略省儿童伤害的人群发生率至少 49%和 53%。 调查数据采集存在系统误差，以至于婴儿和学龄前儿童（<4 岁）和城市居民的伤害最有可能被人群健康调查遗漏。
通过自我报告估计的伤害发生率不能代表安大略省儿童的儿科伤害负担和经历，并且在作为独立数据源进行分析时可能会产生有偏差的风险估计。
