The objective of this study was to assess the independent effect of income on health-related quality of life (HRQL) among older adults in Canada and the United States. Data were obtained from the 2002-2003 Joint Canada/United States Survey of Health. The sample consisted of 755 Canadians and 1,151 Americans aged 65 years or older. HRQL was measured with the multidimensional Health Utilities Index Mark 3 (HUI3). The results indicated that in the elderly population, HRQL was significantly associated with household income in the United States but not in Canada, controlling for sociodemographic and health indicators. Various explanations for the positive linear relationship between HRQL and income in the elderly population are discussed, including the roles of access to health care and socioeconomic inequalities in the United States and Canada.
本研究的目的是评估收入对加拿大和美国老年人健康相关生活质量（HRQL）的独立影响。数据来自2002 - 2003年加拿大/美国健康联合调查。样本包括755名65岁及以上的加拿大人和1151名65岁及以上的美国人。HRQL采用多维健康效用指数Mark 3（HUI3）进行测量。结果表明，在老年人群中，控制社会人口统计学和健康指标后，HRQL在美国与家庭收入显著相关，而在加拿大则不然。文中讨论了老年人群中HRQL与收入之间呈正线性关系的各种解释，包括美国和加拿大在医疗保健可及性和社会经济不平等方面所起的作用。
