To investigate if there are socioeconomic differences in road traffic injuries among Swedish children and adolescents, and if this applies to the same extent to all categories of road users. To assess the modification effect of gender of child.
A closed population-based cohort study based on the Swedish Population and Housing Census of 1985. Individual census records are linked to Sweden's National Hospital Discharge Register (1987-1994).
All children aged 0-15 years in 1985 (approximately 1.5 million subjects) were monitored for five categories of road traffic injuries over eight years, and divided into seven socioeconomic groups on the basis of parental socioeconomic status. Odds ratios and population attributable risks were computed using the children of intermediate and high level salaried employees as reference group.
The injury risks of pedestrians and bicyclists are 20% to 30% higher among the children of manual workers than those of intermediate and high level salaried employees. Socioeconomic differences are greatest for injuries involving motorised vehicles-that is, moped, motorcycle and car. If all children had the same rate as children in the reference group, the rate for all groups would be 25% lower for moped riders and 37% lower for car drivers.
Socioeconomic differences in road traffic injuries are substantial for both boys and girls. Socioeconomic injury-risk differentials increase when young people use motorised vehicles.
调查瑞典儿童和青少年道路交通伤害中是否存在社会经济差异，以及这是否同样适用于所有类别的道路使用者。评估儿童性别所产生的修正效应。
基于1985年瑞典人口与住房普查的基于封闭人群的队列研究。个人普查记录与瑞典国家医院出院登记册（1987 - 1994年）相链接。
对1985年所有0 - 15岁的儿童（约150万受试者）进行了为期八年的五类道路交通伤害监测，并根据父母的社会经济地位将其分为七个社会经济群体。以中级和高级薪资雇员的子女作为参照组计算比值比和人群归因风险。
体力劳动者子女中行人及骑自行车者的伤害风险比中级和高级薪资雇员子女高20%至30%。在涉及机动车辆（即助力车、摩托车和汽车）的伤害方面，社会经济差异最为显著。如果所有儿童的发生率与参照组儿童相同，那么助力车骑行者的所有群体发生率将降低25%，汽车驾驶者的发生率将降低37%。
道路交通伤害中的社会经济差异在男孩和女孩中都很显著。当年轻人使用机动车辆时，社会经济伤害风险差异会增加。
