Research suggests that living in more affluent neighbourhoods positively influences children's health. Relationships with injury are less clear. This study examines variations in rates of unintentional injury hospitalization by neighbourhood income for the population aged 0 to 19 in urban Canada.
Acute-care inpatient hospitalization discharge records from 2001/2002 through 2004/2005 for 0-to 19-year-olds were examined. Injuries were classified using the International Classification of Diseases. Census Dissemination Areas were used as neighbourhood proxies; income quintiles were calculated from the 2001 Census. Age-standardized rates of hospitalization per 10,000 person-years at risk were calculated for each type of injury, by sex, age group and neighbourhood income quintile.
Children and teenagers in the lowest neighbourhood income quintile generally had a higher rate of unintentional injury hospitalization than did those in the highest. The pattern was particularly evident among children aged 0 to 9 in lower-income neighbourhoods for injuries due to land transportation, poisoning, fire, drowning/ suffocation, being cut or pierced, and the natural environment.
Canadian children in lower-income neighbourhoods generally have higher rates of hospitalization due to unintentional injuries, compared with children in higher-income neighbourhoods.
研究表明，生活在较富裕的社区会对儿童的健康产生积极影响。但与伤害的关系还不太清楚。本研究考察了加拿大城市 0 至 19 岁人群中，不同社区收入水平与意外伤害住院率之间的关系。
2001/2002 年至 2004/2005 年期间，对 0 至 19 岁人群的急性住院患者出院记录进行了检查。使用国际疾病分类对损伤进行分类。使用普查传播区作为社区代理；根据 2001 年人口普查计算出收入五分位数。按性别、年龄组和社区收入五分位数计算了每一种损伤类型的每 10000 人年风险标化住院率。
处于最低社区收入五分位数的儿童和青少年意外伤害住院率普遍高于处于最高收入五分位数的儿童和青少年。在低收入社区，0 至 9 岁儿童因陆地交通、中毒、火灾、溺水/窒息、切割或刺穿以及自然环境等原因导致的意外伤害更为明显。
与高收入社区的儿童相比，加拿大低收入社区的儿童意外伤害住院率普遍较高。
