This study used a recent national population survey on childhood and adolescent non-fatal injuries to investigate the effects of recall bias on estimating annual injury rates. Strategies to adjust for recall bias are recommended.
The 1988 Child Health Supplement to the National Health Interview Survey collected 12-month recall information on injuries that occurred to a national sample of 17,110 children aged 0 through 17 years. Using information on timing of interviews and reported injuries, estimated annual injury rates were calculated for 12 accumulative recall periods (from 1 to 12 months).
The data show significantly declining rates, from 24.4 per 100 for a 1-month recall period to 14.7 per 100 for a 12-month recall period. The largest declines were found for the 0- through 4-year-old age group and for minor injuries. Rates of injuries that caused a school loss day, a bed day, surgery, or hospitalization showed higher stability throughout recall periods.
Varying recall periods have profound effects on the patterns of childhood injury epidemiology that emerge from the data. Recall periods of between 1 and 3 months are recommended for use in similar survey settings.
本研究利用最近一项关于儿童和青少年非致命伤害的全国性人口调查，来调查回忆偏倚对估计年度伤害率的影响。建议采用调整回忆偏倚的策略。
1988年全国健康访谈调查的儿童健康补充调查收集了全国17110名0至17岁儿童样本所发生伤害的12个月回忆信息。利用访谈时间和报告伤害的信息，计算了12个累积回忆期（从1个月到12个月）的估计年度伤害率。
数据显示比率显著下降，从1个月回忆期的每100人中有24.4例降至12个月回忆期的每100人中有14.7例。0至4岁年龄组和轻伤的下降幅度最大。导致缺课一天、卧床一天、手术或住院的伤害率在整个回忆期内表现出更高的稳定性。
不同的回忆期对从数据中得出的儿童伤害流行病学模式有深远影响。建议在类似的调查环境中使用1至3个月的回忆期。
