The incidence and severity of injuries occurring on BMX bicycles coming to an Accident and Emergency department (A&E) of a children's hospital have been studied prospectively during a 4-month period in 1984 and compared with the same calendar period 1 year previously, before the increase in BMX sales had occurred. The majority of bicycle accidents in the 1984 period occurred on BMX models. There was a marked increase in the number of injuries seen in 1984 (288) in comparison with 1983 (188), reflecting the increased use of bicycles by children due to the current popularity of BMX models. Although there was an increase in minor injuries in 1984 (182) compared with 1983 (112), the number of severe injuries was less-56 in 1984 (20 per cent) and 68 in 1983 (37 per cent). BMX bicycles, although increasing the number of A&E attendances, have not caused a rise in the number of severe injuries related to bicycles in Edinburgh.
1984年，在一家儿童医院的急诊部，对前来就诊的因骑BMX自行车而受伤的发生率和严重程度进行了为期4个月的前瞻性研究，并与BMX自行车销量增加之前的1983年同一日历时段进行了比较。1984年期间，大多数自行车事故发生在BMX车型上。与1983年（188例）相比，1984年受伤人数显著增加（288例），这反映出由于当前BMX车型很受欢迎，儿童骑自行车的人数有所增加。虽然1984年轻伤人数（182例）比1983年（112例）有所增加，但重伤人数有所减少——1984年为56例（20%），1983年为68例（37%）。BMX自行车虽然增加了急诊就诊人数，但在爱丁堡并没有导致与自行车相关的重伤人数上升。
