This study investigated the factors associated with the premature graduation into seatbelts for Australian children aged 4-11 years. From 699 child restraint use questionnaires, 195 children were identified as meeting the booster seat height-weight criteria (height: 100-145 cm and weight: 14-26 kg). Of these children, 44% were correctly traveling in a booster seat, while 56% had been moved prematurely into a seatbelt. A multivariable logistic regression model showed that there were a number of key predictors associated with the premature graduation to seatbelts. For example, children who were moved prematurely into a seatbelt were more likely to be older, have other children travelling in the vehicle and have younger parents compared to children appropriately restrained in a booster seat. In addition, there was a significant interaction between vehicle type and parent's household income. Based on the findings of this study, a number of recommendations are made for strategies to enhance appropriate restraint use for this age group, as well as for future research.
本研究调查了澳大利亚4至11岁儿童过早改用安全带的相关因素。从699份儿童约束装置使用调查问卷中，识别出195名儿童符合增高座椅的身高体重标准（身高：100至145厘米，体重：14至26千克）。在这些儿童中，44%正确使用增高座椅乘车，而56%过早改用了安全带。多变量逻辑回归模型显示，有许多关键预测因素与过早改用安全带有关。例如，与正确使用增高座椅的儿童相比，过早改用安全带的儿童年龄更大、车内有其他儿童同行且父母年龄更小。此外，车辆类型与父母家庭收入之间存在显著交互作用。基于本研究的结果，针对提高该年龄组儿童正确使用约束装置的策略以及未来研究提出了一些建议。
