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.
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。
