To examine the association of life-course socioeconomic status (SES) and mobility with allostatic load (AL) in a large cohort of Chinese middle-aged and older adults.
Drawing on data from 17 552 middle-aged and older adults from three waves of a longitudinal study conducted in China in 2011-2015, generalized estimating equation (GEE) models were used for the overall sample and subsample to examine the association between life-course SES and AL.
On the whole, those who were literate had lower AL (β = -0.034, 95% CI = -0.065, -0.004), while those with a non-agricultural occupation (β = 0.093, 95% CI = 0.065, 0.120) and better financial status in childhood (β = 0.037, 95% CI = 0.012, 0.063) or adulthood (β = 0.033, 95% CI = 0.009, 0.058) had higher AL. In terms of SES mobility, a stable high education was associated with lower AL (β = -0.041, 95% CI = -0.078, -0.004). Upward (β = 0.090, 95% CI = 0.061, 0.120) or stable high (β = 0.075, 95% CI = 0.025, 0.125) occupation was related to higher AL. Downward (β = 0.034, 95% CI = 0.003, 0.064) or stable high (β = 0.072, 95% CI = 0.037, 0.107) financial status was associated with higher AL. Education manifested no associations with AL for the rural and men samples. Financial status showed no relationship with AL for the urban sample.
Our findings demonstrate the importance of applying life-course models for gaining an understanding of SES and AL. Efforts to lower AL among Chinese middle-aged and older adults should consider childhood and current SES status, as well as different subgroups. Geriatr Gerontol Int 2022; 22: 425-432.
在一大群中国中老年成年人中，研究生命历程社会经济地位（SES）和流动性与累积性生理压力负荷（AL）之间的关联。
利用2011 - 2015年在中国进行的一项纵向研究的三波数据中的17552名中老年成年人的数据，对总体样本和子样本使用广义估计方程（GEE）模型来研究生命历程SES与AL之间的关联。
总体而言，识字者的AL较低（β = -0.034，95%置信区间 = -0.065，-0.004），而从事非农业职业者（β = 0.093，95%置信区间 = 0.065，0.120）以及童年（β = 0.037，95%置信区间 = 0.012，0.063）或成年期（β = 0.033，95%置信区间 = 0.009，0.058）经济状况较好者的AL较高。在SES流动性方面，稳定的高学历与较低的AL相关（β = -0.041，95%置信区间 = -0.078，-0.004）。职业向上流动（β = 0.090，95%置信区间 = 0.061，0.120）或稳定处于较高职业水平（β = 0.075，95%置信区间 = 0.025，0.125）与较高的AL相关。经济状况向下流动（β = 0.034，95%置信区间 = 0.003，0.064）或稳定处于较高水平（β = 0.072，95%置信区间 = 0.037，0.107）与较高的AL相关。教育程度在农村样本和男性样本中与AL无关联。经济状况在城市样本中与AL无关系。
我们的研究结果表明应用生命历程模型来理解SES和AL的重要性。降低中国中老年成年人AL的努力应考虑童年和当前的SES状况以及不同亚组。《老年医学与老年病学国际杂志》2022年；22：425 - 432。
