Abstract：
OBJECTIVE: The incidence of self-harm is an important indicator in suicide surveillance and a target outcome for suicide prevention. Self-harm rates vary by geographic location and rurality appears to be a risk factor. The objectives of this study were to estimate rates of self-harm hospitalization in Canada over a 5-year period by sex and age group, and examine relationships between self-harm and rurality.
METHODS: Hospitalizations related to self-harm were identified in a national dataset (the Discharge Abstract Database) for all patients aged 10 years or older who were discharged from hospital between 2015 and 2019. Self-harm hospitalization rates were calculated and stratified by year, sex, age group, and level of rurality, as measured using the Index of Remoteness. A Poisson regression was fit to estimate rate ratios for the levels of rurality.
RESULTS: Rates of self-harm hospitalization were higher for females than males across all levels of rurality and increased with each level for both sexes, except for among young males. The widest rural-to-urban disparities were observed for the 10-19 and 20-34-year old age groups. Females aged 10-19 in very remote areas had the highest self-harm hospitalization rate.
CONCLUSIONS: The rate of self-harm hospitalization in Canada varied by sex, age group, and level of rurality. Clinical and community-based interventions for self-harm, such as safety planning and increased access to mental health services, should be tailored to the differential risks across geographic contexts.

摘要：
目的：自我伤害的发生率是自杀监测的重要指标，也是自杀预防的目标结局。自我伤害率因地理位置而异，乡村似乎是一个风险因素。这项研究的目的是按性别和年龄组估计加拿大5年内的自我伤害住院率。并检查自我伤害和乡村之间的关系。
方法：在国家数据集（出院摘要数据库）中，针对2015年至2019年间出院的所有10岁或以上的患者，确定了与自我伤害相关的住院治疗。自残住院率按年计算并分层，性别,年龄组,和乡村水平，使用远程指数衡量。泊松回归适合于估算乡村水平的比率。
结果：在各个乡村等级中，女性的自我伤害住院率高于男性，并且男女均随每个等级的增加而增加，除了年轻的男性。10-19岁和20-34岁年龄组的城乡差距最大。在非常偏远的地区，10-19岁的女性的自我伤害住院率最高。
结论：加拿大的自我伤害住院率因性别而异，年龄组,和乡村水平。基于临床和社区的自我伤害干预措施，例如安全规划和增加获得精神卫生服务的机会，应根据不同地理环境的不同风险进行调整。
