To examine if there are systematic differences in the predictors of self-rated health (SRH) and to examine the relationship between SRH and health care utilization across socioeconomic groups.
We used cross-sectional data from the Canadian Community Health Survey linked to the Ontario Health Insurance Plan (N=17,109). We examined relative differences in the factors associated with different levels of SRH across socioeconomic groups (as assessed by education and household income) using probit models separately for men and women. We then examined differences in expected health care costs, as assessed by adjusted clinical group weights using administrative health care records, between socioeconomic groups within the same level of SRH.
We found limited differences across the predictive ability of a broad range of physical, mental, health service/care utilization, and health behavior variables on SRH across socioeconomic groups. In addition, no differences were found in the expected health care utilization costs across socioeconomic groups within the same level of SRH.
The results of this study suggest that SRH assesses a broad variety of factors, including physical health status, mental health status, health service/care utilization, and health behaviors, relatively equally across socioeconomic groups, measured as either education or income.
研究自我评估健康（SRH）的预测因素是否存在系统差异，并检验不同社会经济群体中 SRH 与医疗保健利用之间的关系。
我们使用了来自加拿大社区健康调查的横断面数据，并与安大略省医疗保险计划相关联（N=17109）。我们使用概率模型分别对男性和女性进行了研究，以评估不同社会经济群体（通过教育和家庭收入评估）中与不同水平的 SRH 相关的因素的相对差异。然后，我们使用行政医疗保健记录中的调整临床组权重，评估了相同 SRH 水平内不同社会经济群体之间的预期医疗保健费用差异。
我们发现，在广泛的身体、心理、医疗服务/利用和健康行为变量对社会经济群体中 SRH 的预测能力方面，存在有限的差异。此外，在相同的 SRH 水平内，不同社会经济群体之间的预期医疗保健利用费用没有差异。
这项研究的结果表明，SRH 相对平等地评估了广泛的因素，包括身体健康状况、心理健康状况、医疗服务/利用和健康行为，而这些因素是通过教育或收入来衡量的。
