Early self-regulation is a foundation for lifelong wellness and can be shaped by the interplay among several vital exposures. In this study, we examined the emergence of reliable profiles based upon exposure to risk and protective factors in infancy, determined if sociodemographic resources predict profile membership, and determined if these profiles predict early regulatory behaviors in a sample of infants reared in low-income homes. Data were collected from a sample of primarily Black or White mother-infant dyads living in low-income homes in the Midwest (n = 222) during the infants’ first year of life (mean maternal age at enrollment: 26.29 years; range 18−43 years). Exposures included mother-infant interactions; father support; maternal depression, stress, and self-efficacy; home environment; food security; and breastfeeding duration. Sociodemographic resources included poverty status; economic hardship; maternal education, employment, and age; parental marital status; and infant race and sex. Infant regulatory behaviors were measured with the Infant Behavior Questionnaire-Revised Very Short Form effortful control subscale (mean age 11 months; range 8.5−14.3 months). Latent profile analysis was used to profile infants by risk and protective exposures. Regression was used to differentiate profiles by sociodemographic resources and to predict infant regulatory behavior from profiles. Three profiles emerged: low father support, good maternal mental health, and poor maternal mental health. A married mother, less economic hardship, and working mothers predicted infant exposure to good maternal mental health. Infant regulatory behavior was best when the infant was exposed to the good maternal mental health profile. Implications for future research are discussed.

早期的自我调节是终身健康的基础，并且可以通过几种重要暴露之间的相互作用来塑造。在这项研究中，我们检查了基于婴儿期暴露于风险和保护因素的可靠配置文件的出现，确定社会人口资源是否预测配置文件成员资格，并确定这些配置文件是否预测在低收入家庭抚养的婴儿样本中的早期监管行为. 数据是从居住在中西部低收入家庭的主要黑人或白人母婴样本中收集的（n= 222）在婴儿出生的第一年（入学时母亲的平均年龄：26.29 岁；范围 18-43 岁）。暴露包括母婴互动；父亲的支持；产妇抑郁、压力和自我效能；家居环境；食品安全; 和母乳喂养时间。社会人口资源包括贫困状况；经济困难；孕产妇教育、就业和年龄；父母婚姻状况；和婴儿的种族和性别。使用婴儿行为问卷修订的非常简短的努力控制分量表（平均年龄 11 个月；范围 8.5-14.3 个月）测量婴儿的调节行为。潜在概况分析用于通过风险和保护性暴露来分析婴儿。回归被用来区分社会人口资源的概况，并从概况中预测婴儿的调节行为。父亲支持率低，母亲心理健康好，母亲心理健康差。已婚母亲、经济困难较少和有工作的母亲预测婴儿的母亲心理健康状况良好。当婴儿暴露于良好的母亲心理健康状况时，婴儿的调节行为是最好的。讨论了对未来研究的影响。
