Our study aims to investigate the association between SRH and all-cause mortality, and to investigate whether the SRH-mortality association varies across different socioeconomic status (SES) groups among middle-aged and older Chinese adults. We used data from China Health and Retirement Longitudinal Study (CHARLS), including 11,762 participants for the final analysis. Cox proportional hazards regression was conducted to investigate the association between SRH status and subsequent mortality. There were 724 death events occurred. The results were shown that fair/poor SRH participants tend to die than better SRH peers (HR 1.46, 95% CI 1.12-1.91). The association only occurred in those with rural residency (HR 1.46, 95% CI 1.05-2.04), those who were literate (HR 1.65, 95% CI 1.17-2.33), those with above-average household income (HR 1.95, 95% CI 1.15-3.29) and those working in agriculture and below (HR 1.38, 95% CI 1.02-1.88). In conclusion, worse SRH may be a predictor of all-cause mortality among middle-aged and elderly Chinese, especially in people with rural residency, literacy, above-average household income and working in agriculture and below.
我们的研究旨在探讨主观健康状况（SRH）与全因死亡率之间的关联，并探讨这种 SRH-死亡率关联是否因中国中年及以上成年人的不同社会经济地位（SES）群体而异。我们使用了中国健康与养老追踪调查（CHARLS）的数据，最终分析包括 11762 名参与者。采用 Cox 比例风险回归来研究 SRH 状况与随后的死亡率之间的关联。共发生了 724 例死亡事件。结果表明，健康状况不佳的参与者比健康状况较好的参与者更容易死亡（HR 1.46，95%CI 1.12-1.91）。这种关联仅发生在农村居住者（HR 1.46，95%CI 1.05-2.04）、识字者（HR 1.65，95%CI 1.17-2.33）、家庭收入高于平均水平者（HR 1.95，95%CI 1.15-3.29）和从事农业及以下工作者（HR 1.38，95%CI 1.02-1.88）中。总之，较差的 SRH 可能是中国中年及以上老年人全因死亡率的一个预测因素，尤其是在农村居住者、识字者、家庭收入高于平均水平者和从事农业及以下工作者中。
