Seniors constitute the largest group of hospital users. The increasing share of immigrants in Canada's senior population can affect the demand for hospital care.
This study used the linked 2006 Census-Hospital Discharge Abstract Database to examine hospitalization during the 2004-to-2006 period, by immigrant status, of Ontario seniors living in the community. Hospitalization was assessed with logistic regressions; cumulative length of stay, with zero-truncated negative binomial regressions. All-cause hospitalization and hospitalizations specific to circulatory and digestive diseases were examined.
Immigrant seniors had significantly low age-/sex-adjusted odds of hospitalization, compared with Canadian-born seniors (OR = 0.81). The odds varied from 0.4 among East Asians to 0.89 among Europeans, and rose with length of time since arrival from 0.54 for recent (1994 to 2003) to 0.86 for long-term (before 1984) immigrants. Adjustment for demographic and socio-economic characteristics did not change the overall patterns. Immigrants' cumulated length of hospital stay tended to be shorter than or similar to that of Canadian-born seniors.
Immigrant seniors, especially recent arrivals, had lower odds of hospitalization and similar time in hospital, compared with Canadian-born seniors. These patterns likely reflect differences in health status. Variations by world region and disease reflect the diverse health care needs of immigrant seniors.
老年人是医院就诊者中最大的群体。加拿大老年人中的移民比例不断增加，可能会影响对医院护理的需求。
本研究使用 2006 年人口普查-医院出院摘要数据库，通过社区居住的安大略省老年人的移民身份，调查了 2004 年至 2006 年期间的住院情况。采用逻辑回归评估住院情况；采用零截断负二项回归评估累积住院时间。检查了所有原因的住院和特定于循环系统和消化系统疾病的住院情况。
与加拿大出生的老年人相比，老年移民的住院调整后年龄/性别比值显著较低（OR=0.81）。比值从东亚的 0.4 到欧洲的 0.89 不等，随着到达时间的延长而增加，最近（1994 年至 2003 年）移民的比值为 0.54，长期（1984 年之前）移民的比值为 0.86。调整人口统计学和社会经济特征并没有改变总体模式。移民的累积住院时间往往短于或与加拿大出生的老年人相似。
与加拿大出生的老年人相比，老年移民，尤其是最近到达的移民，住院的几率较低，住院时间也相似。这些模式可能反映了健康状况的差异。按世界区域和疾病的差异反映了移民老年人多样化的医疗保健需求。
