Much literature in the US documents an intergenerational transmission of birthing person and perinatal morbidity in socioeconomically disadvantaged groups. A separate line of work indicates that family cash transfers may improve life chances of low-income families well into adulthood. By exploiting a quasi-random natural experiment of a large family cash transfer among a southeastern American Indian (AI) tribe in rural North Carolina, we examine whether a "perturbation" in socioeconomic status during childhood improves birthing person/perinatal outcomes when they become parents themselves. We acquired birth records on 6805 AI and non-AI infants born from 1995 to 2018. Regression methods to examine effect modification tested whether the birthing person's American Indian (AI) status and exposure to the family cash transfer during their childhood years corresponds with improvements in birthing person and perinatal outcomes. Findings show an increase in age at childbearing (coef: 0.15 years, 95% confidence interval [CI]: 0.05, 0.25) and a decrease in pre-pregnancy body mass index (BMI; coef: -0.42, 95% CI: -0.76, -0.09) with increased duration of cash transfer exposure during childhood. The odds of large-for-gestational age at delivery, as well as mean infant birthweight, is also reduced among AI births whose birthing person had relatively longer duration of exposure to the cash transfer. We, however, observe no relation with other birthing person/perinatal outcomes (e.g., tobacco use during pregnancy, preterm birth). In this rural AI population, cash transfers in one generation correspond with improved birthing person and infant health in the next generation.
美国的许多文献都记录了社会经济弱势群体中生育者及围产期发病率的代际传递情况。另一项研究表明,家庭现金转移支付可能会显著改善低收入家庭直至成年期的生活机遇。通过利用北卡罗来纳州农村一个美国东南部印第安部落进行的一项大型家庭现金转移支付的准随机自然实验,我们研究了童年时期社会经济地位的“扰动”是否会在生育者自己成为父母时改善其生育及围产期结局。我们获取了1995年至2018年出生的6805名印第安及非印第安婴儿的出生记录。用于检验效应修正的回归方法测试了生育者的美国印第安(AI)身份以及其童年时期接受家庭现金转移支付的情况是否与生育者及围产期结局的改善相对应。研究结果显示,随着童年时期现金转移支付暴露时间的增加,生育年龄有所增加(系数:0.15岁,95%置信区间[CI]:0.05,0.25),孕前体重指数(BMI)有所下降(系数:-0.42,95%CI:-0.76,-0.09)。对于生育者接受现金转移支付时间相对较长的印第安婴儿出生情况,大于胎龄儿的几率以及婴儿平均出生体重也有所降低。然而,我们未观察到与其他生育者/围产期结局(例如孕期吸烟、早产)之间存在关联。在这个农村印第安人群体中,一代人中的现金转移支付与下一代生育者及婴儿健康状况的改善相对应。
