目的探讨母亲产前抑郁对婴儿期养育方式、随后的儿童期调节和3岁时体重指数（BMI）的影响。研究设计样本（N = 284）包括青少年母亲（n = 157）、低教育程度成年母亲（n = 69）和高教育程度成年母亲（n = 58）及其第一个孩子。母亲抑郁症状产前评估通过自我报告;观察方法和自我报告被用来评估母亲的养育在4，6，8个月和儿童的监管在18，24，30个月的年龄。儿童BMI测量在36个月的年龄在laborator.Results结构方程模型支持中介过程，如母亲谁报告更多的抑郁症状产前表现出积极的养育在婴儿期。反过来，不太积极的父母在幼儿期预测较低水平的儿童监管，这预测较高的儿童BMI在36个月的年龄，即使在控制婴儿出生体重和并发的母亲BMI。模型比较组（青少年母亲，成人低学历的母亲，成人高学历的母亲）表明，母亲抑郁症，养育子女和儿童监管的平均差异，但跨groups.Conclusions预测模式相似本研究提供的证据级联心理社会过程开始产前和持续通过婴儿期，幼儿期，并进入幼儿期。研究结果对全家庭干预策略具有影响，有助于降低儿童早发性肥胖的风险。
Objective To investigate the effects of mothers' prenatal depression on parenting during infancy, ensuing childhood regulation, and body mass index (BMI) at age 3 years.Study design The sample (N = 284) included teen mothers (n = 157), adult mothers with low education (n = 69), and adult mothers with high education (n = 58), and their first-born children. Maternal depressive symptoms were assessed prenatally through self-report; observational methods and self-report were used to assess mothers' parenting at 4, 6, and 8 months and children's regulation at 18, 24, and 30 months of age. Child BMI was measured at 36 months of age in the laboratory.Results Structural equation modeling supported mediating processes such that mothers who reported more depressive symptoms prenatally exhibited less positive parenting during infancy. In turn, less positive parenting predicted lower levels of child regulation during toddlerhood, which predicted higher child BMIs at 36 months of age, even after controlling for infant birth weight and concurrent maternal BMI. Models comparing groups (teen mothers, adult low-educated mothers, and adult-high educated mothers) indicated mean differences in maternal depression, parenting, and child regulation, but similar patterns of prediction across groups.Conclusions The present study provides evidence of cascading psychosocial processes beginning prenatally and continuing through infancy, toddlerhood, and into early childhood. Results have implications for family-wide intervention strategies to help lower the risk for early onset obesity in children.
