We examined the magnitude and determinants of socioeconomic disparities in disability-free life expectancy and life expectancy at age 65 (DFLE and LE) in China. Data from Chinese Longitudinal Healthy Longevity Survey collected during 2011-2018 (8,184 participants aged ≥65) were used. Socioeconomic status (SES) was measured by economic status (ES), and education, respectively. Multistate Markov models and microsimulations were fitted to estimate DFLE and LE. LE between high- and low-ES groups differed by 2.20 years for males and 2.04 years for females. The DFLE disparity in ES was 1.51 and 1.29 years for males and females, respectively. Not undergoing physical examinations, inadequate fruit/vegetable intake, and stress contributed to 35.10% and 57.36% of DFLE disparity in ES, as well as 26.36% and 42.65% of LE disparity for males and females, respectively. These disparities in education and ES were of a similar magnitude, while the above factors contributed little to education disparity. Socioeconomic disparities in DFLE and LE existed in China. Physical examination, fruit/vegetable intake and stress partly explained these disparities.
我们考察了中国无残疾预期寿命和 65 岁预期寿命（DFLE 和 LE）方面社会经济差异的程度和决定因素。使用了 2011-2018 年期间收集的中国纵向健康长寿调查（8184 名年龄≥65 岁的参与者）的数据。社会经济地位（SES）分别通过经济状况（ES）和教育来衡量。拟合多状态马尔可夫模型和微观模拟来估计 DFLE 和 LE。男性高 SES 和低 SES 组之间的 LE 差异为 2.20 年，女性为 2.04 年。男性和女性 ES 的 DFLE 差异分别为 1.51 和 1.29 年。未进行体检、水果/蔬菜摄入不足和压力导致 ES 差异的 35.10%和 57.36%，以及男性和女性 LE 差异的 26.36%和 42.65%。教育和 ES 方面的这些差异程度相似，而上述因素对教育差异的贡献很小。中国存在 DFLE 和 LE 方面的社会经济差异。体检、水果/蔬菜摄入和压力部分解释了这些差异。
