Our study measured the change in head injuries and deaths among motorcycle users in Cu Chi district, a suburban district of Ho Chi Minh City.
Hospital records for road traffic injuries (RTIs) were collected from the Cu Chi Trauma Centre and motorcycle-related death records were obtained from mortality registries in commune health offices. Head injury severity was categorized using the Abbreviated Injury Score (AIS). Rate ratios (RRs) were used to compare rates pre- and post-law (2005/2006-2009/2010). Cu Chi's population, stratified by year, age, and sex, was used as the denominator.
Of records identifying the transportation mode at the time of injury, motorcyclists accounted for most injuries (3,035, 87%) and deaths (238, 90%). Head injuries accounted for 70% of motorcycle-related hospitalizations. Helmet use was not recorded in any death records and not in 97% of medical records. Males accounted for most injuries (73%) and deaths (88%). The median age was 28 years and 32 years for injuries and deaths, respectively. Compared to the pre-law period, rates of motorcycle injuries (RR = 0.53; 95% confidence interval [CI], 0.49-0.58), head injuries (RR = 0.35; 95% CI, 0.31-0.39), severe head injuries (RR = 0.47; 95% CI, 0.34-0.63), and deaths (RR = 0.69; 95% CI, 0.53-0.89) significantly decreased in the post-law period.
Rates of head injuries and deaths among motorcycle riders decreased significantly after implementation of the mandatory helmet law in Vietnam. To further examine the impact of the motorcycle helmet law, including compliance and helmet quality, further emphasis should be placed on gathering helmet use data from injured motorcyclists.
本研究旨在测量胡志明市郊区古芝区摩托车使用者的头部损伤和死亡人数变化。
从古芝创伤中心收集道路交通伤害（RTI）的医院记录，并从公社卫生办公室的死亡率登记处获得与摩托车相关的死亡记录。使用简明损伤评分（AIS）对头部损伤严重程度进行分类。使用率比（RR）比较法律实施前后（2005/2006-2009/2010 年）的比率。古芝人口按年份、年龄和性别分层，用作分母。
在识别受伤时交通方式的记录中，摩托车手占大多数受伤者（3035 人，87%）和死亡者（238 人，90%）。头部损伤占摩托车相关住院治疗的 70%。在任何死亡记录中均未记录头盔使用情况，在 97%的医疗记录中也未记录头盔使用情况。男性占大多数受伤者（73%）和死亡者（88%）。损伤和死亡的中位数年龄分别为 28 岁和 32 岁。与法律实施前相比，摩托车受伤率（RR=0.53；95%置信区间[CI]，0.49-0.58）、头部受伤率（RR=0.35；95%CI，0.31-0.39）、严重头部受伤率（RR=0.47；95%CI，0.34-0.63）和死亡率（RR=0.69；95%CI，0.53-0.89）在法律实施后均显著下降。
在越南实施强制性头盔法后，摩托车骑手的头部损伤和死亡人数显著下降。为了进一步研究摩托车头盔法的影响，包括遵守情况和头盔质量，应进一步强调从受伤摩托车手那里收集头盔使用数据。
