Childhood maltreatment influences adult physical health through cascading effects over the life course and it is critical to identify intervening processes. Marital quality has significant implications for adult physical health via cognitive, emotional, and behavioral pathways and may be a viable pathway. Given that cardiometabolic biomarkers are associated with the leading causes of death in the United States, the current study longitudinally investigated marital quality, health locus of control, and eating habits in a serial mediation model linking childhood maltreatment to high density lipoprotein (HDL) and low density lipoprotein (LDL). Using a sample of 352 adults from the study of Midlife Development in the United States, we used three waves of data to test our hypotheses. Results of structural equation models indicate that although all the hypothesized direct effects were statistically significant, the serial indirect effects were non-significant. Childhood maltreatment was associated with a lower quality marriage, marital quality was associated with higher levels of health locus of control which, in turn, was associated with healthier eating habits. Finally, healthier eating habits were associated with greater HDL, but not lower LDL. Additionally, marital quality exerted a direct effect on LDL and mediated the relationship between maltreatment and LDL, but not HDL. For researchers, marital quality appears to be a mechanism linking childhood maltreatment to cardiometabolic biomarkers, yet health locus of control and eating habits do not appear to have strong effects. For clinicians, strengthening the couple relationship among survivors of maltreatment appears to have health promotive effects over time.

童年虐待通过婚姻质量与心脏代谢生物标志物纵向相关：健康控制点和饮食习惯重要吗？

童年虐待通过生命历程中的连锁效应影响成人的身体健康，识别干预过程至关重要。婚姻质量通过认知、情感和行为途径对成人身体健康产生重大影响，并且可能是一条可行的途径。鉴于心脏代谢生物标志物与美国的主要死亡原因相关，当前的研究在一系列中介模型中纵向调查了婚姻质量、健康控制点和饮食习惯，该模型将儿童虐待与高密度脂蛋白 (HDL) 和低密度脂蛋白 (HDL) 联系起来。密度脂蛋白（LDL）。我们使用美国中年发展研究中的 352 名成年人作为样本，使用三波数据来检验我们的假设。结构方程模型的结果表明，虽然所有假设的直接效应在统计上都是显着的，但一系列的间接效应并不显着。童年虐待与较低质量的婚姻有关，婚姻质量与较高水平的健康控制点相关，而健康控制点又与更健康的饮食习惯相关。最后，更健康的饮食习惯与更高的高密度脂蛋白相关，但与更低的低密度脂蛋白无关。此外，婚姻质量对低密度脂蛋白有直接影响，并介导虐待与低密度脂蛋白之间的关系，但不介导高密度脂蛋白之间的关系。对于研究人员来说，婚姻质量似乎是将儿童虐待与心脏代谢生物标志物联系起来的一种机制，但健康控制点和饮食习惯似乎并没有产生强烈的影响。对于临床医生来说，随着时间的推移，加强虐待幸存者之间的夫妻关系似乎会对健康产生促进作用。
