In 1999, an estimated 8800 children younger than 15 months were treated in hospital emergency departments in the United States for injuries associated with infant walkers. Thirty-four infant walker-related deaths were reported from 1973 through 1998. The vast majority of injuries occur from falls down stairs, and head injuries are common. Walkers do not help a child learn to walk; indeed, they can delay normal motor and mental development. The use of warning labels, public education, adult supervision during walker use, and stair gates have all been demonstrated to be insufficient strategies to prevent injuries associated with infant walkers. To comply with the revised voluntary standard (ASTM F977-96), walkers manufactured after June 30, 1997, must be wider than a 36-in doorway or must have a braking mechanism designed to stop the walker if 1 or more wheels drop off the riding surface, such as at the top of a stairway. Because data indicate a considerable risk of major and minor injury and even death from the use of infant walkers, and because there is no clear benefit from their use, the American Academy of Pediatrics recommends a ban on the manufacture and sale of mobile infant walkers. If a parent insists on using a mobile infant walker, it is vital that they choose a walker that meets the performance standards of ASTM F977-96 to prevent falls down stairs. Stationary activity centers should be promoted as a safer alternative to mobile infant walkers.
1999年，在美国，估计有8800名15个月以下的儿童因与婴儿学步车相关的伤害而在医院急诊科接受治疗。1973年至1998年期间，共报告了34起因婴儿学步车导致的死亡事件。绝大多数伤害是由于从楼梯上跌落造成的，头部受伤很常见。学步车并不能帮助孩子学会走路；事实上，它们会延迟孩子正常的运动和智力发育。使用警示标签、开展公众教育、在使用学步车时由成人监管以及安装楼梯门，都已被证明不足以防止与婴儿学步车相关的伤害。为符合修订后的自愿标准（ASTM F977 - 96），1997年6月30日之后生产的学步车必须比36英寸宽的门道更宽，或者必须具备制动机制，以便在一个或多个轮子离开骑行表面（如在楼梯顶部）时使学步车停下。由于数据表明使用婴儿学步车存在受重伤和轻伤甚至死亡的重大风险，且使用学步车没有明显益处，美国儿科学会建议禁止生产和销售可移动婴儿学步车。如果家长坚持使用可移动婴儿学步车，至关重要的是他们要选择符合ASTM F977 - 96性能标准的学步车，以防止从楼梯上跌落。应推广固定活动中心作为可移动婴儿学步车更安全的替代品。
