Children ages 5-14 years have the highest rate of bicycle-related injuries in the country. Bicycle helmets can prevent head and brain injuries, which represent the most serious type of bicycle-related injury.
This paper compares children's bicycle helmet use to that estimated from an earlier study, and explores regional differences in helmet use by existing helmet legislation.
This study was a cross-sectional, list-assisted random-digit-dial telephone survey. Interviews were completed by 9,684 respondents during 2001-2003. The subset with at least one child in the household age 5-14 years (2,409 respondents) answered questions about bicycle helmet use for a randomly selected child in their household.
Almost half (48%) of the children always wore their helmet, 23% sometimes wore their helmet, and 29% never wore their helmet. Helmet wearing was significantly associated with race, ethnicity, and child age but was not associated with the sex of the child. Other significant predictors of use included household income, household education, census region, and bicycle helmet law status. Statewide laws were more effective than laws covering smaller areas. The proportion of children who always wore a helmet increased from 25% in 1994 to 48% in 2001-2002. Significant increases in helmet use from 20% to 26% were seen among both sexes, younger (5-9 years) and older (10-14 years) children, and in all four regions of the country.
While there has been substantial progress in the number of children who always wear their helmets, more than half do not. Further progress will require using a combination of methods that have been shown to successfully promote consistent helmet use.

5-14 岁儿童是全美自行车事故相关受伤率最高的群体。自行车头盔可以预防头部和大脑损伤，这是自行车事故相关伤害中最严重的类型。
本文将比较儿童自行车头盔的使用情况与之前研究中的估计值，并探讨现行头盔立法地区间头盔使用的差异。
本研究为横断面、名单辅助随机数字拨号电话调查。2001-2003 年期间，共完成了 9684 名受访者的访谈。有至少一名 5-14 岁儿童的家庭子集（2409 名受访者）回答了与家中随机选择的儿童自行车头盔使用情况相关的问题。
近一半（48%）的儿童始终佩戴头盔，23%的儿童有时佩戴头盔，29%的儿童从不佩戴头盔。头盔佩戴与种族、民族和儿童年龄显著相关，但与儿童性别无关。使用的其他重要预测因素包括家庭收入、家庭教育程度、人口普查区和自行车头盔法律地位。全州范围的法律比覆盖较小区域的法律更有效。始终佩戴头盔的儿童比例从 1994 年的 25%增加到 2001-2002 年的 48%。在所有四个地区，男女儿童、年龄较小（5-9 岁）和较大（10-14 岁）的儿童，头盔使用率都从 20%显著增加到 26%。
虽然始终佩戴头盔的儿童人数显著增加，但仍有一半以上的儿童不佩戴头盔。要进一步取得进展，需要综合运用已被证明能成功促进头盔持续使用的各种方法。
