The underlying mechanisms through which family economic adversity influences child health are less understood. Taking a process-oriented approach, this study examined maternal mental health and investment in children, child health insurance, and child healthcare as mediators linking family economic hardship (FEH) to child health.
A structural equation modeling was applied to test the hypothesized mediating model.
After adjustment for sociodemographic risk factors, results revealed: (1) a significant direct path linking FEH to poor child health (effect size = .372), and (2) six significant mediating pathways (total effect size = .089). In two mediating pathways, exposures to FEH undermined mothers' mental health: in the first pathway poor maternal mental health led to decreased parental investment, which, in turn, contributed to poor child health, whereas in the second pathway the adverse effect of poor maternal mental health was cascaded through child unmet healthcare need, which resulted in poor child health. One pathway involved child insurance status, where the effect of FEH increased the likelihood to be uninsured, which led to unmet healthcare need, and, in turn, to poor health. Three pathways involved preventive care: in one pathway FEH contributed to poor preventive care, which led to unmet healthcare need and then to poor health; in the other two pathways where poor preventive care respectively gave rise to decreased investment in children or poor maternal mental health, which further contributed to poor child health.
Results suggest that the association between FEH and children's health is mediated by multiple pathways.
家庭经济困境影响儿童健康的潜在机制尚不清楚。本研究采用面向过程的方法,考察了母亲心理健康和对子女的投入、儿童健康保险以及儿童医疗保健作为将家庭经济困难(FEH)与儿童健康联系起来的中介因素。
应用结构方程模型来检验假设的中介模型。
在对社会人口学风险因素进行调整后,结果显示:(1)FEH与儿童健康状况不佳之间存在显著的直接路径(效应量 = 0.372),以及(2)六条显著的中介路径(总效应量 = 0.089)。在两条中介路径中,FEH暴露会损害母亲的心理健康:在第一条路径中,母亲心理健康不佳导致父母投入减少,进而导致儿童健康状况不佳;而在第二条路径中,母亲心理健康不佳的不利影响通过儿童未满足的医疗需求层层传导,最终导致儿童健康状况不佳。一条路径涉及儿童保险状况,FEH的影响增加了未参保的可能性,这导致了未满足的医疗需求,进而导致健康状况不佳。三条路径涉及预防性保健:在一条路径中,FEH导致预防性保健不足,进而导致未满足的医疗需求,最终导致健康状况不佳;在另外两条路径中,预防性保健不足分别导致对儿童的投入减少或母亲心理健康不佳,这进一步导致儿童健康状况不佳。
结果表明,FEH与儿童健康之间的关联是由多种途径介导的。
