目标.本研究探讨了体重指数（BMI）百分位数从出生到青春期早期的发展方式，BMI百分位数是成年期超重和心血管疾病的一个确定的危险因素。此外，我们还研究了社会心理因素，如父母教养方式和母亲抑郁症，是否介导了社会经济地位（SES）和BMI增长之间的联系。数据来自国家儿童健康和人类发展研究所（NICHD）早期儿童保育和青年发展研究（SECCYD）的第13期，这是一项纵向研究，跟踪了美国10个社区从出生到11岁的儿童。我们应用生长混合模型来识别BMI发展的不同亚型。在这些模型中，我们进行了类间和类内中介分析，以检查是否SES预测类成员或通过母亲抑郁症和养育方式在每个类内的发展差异。结果确定了BMI百分位数增长的三种典型轨迹，升高，稳定增加和稳定。我们发现了班级间和班级内调解的证据，表明SES可以通过多种途径影响BMI的发展。这些发现补充了一项研究，即在一个低SES的家庭中，与陷入以BMI相对于同龄人的早期和持久增加为特征的发展模式有关，并且这种关联部分归因于母亲的抑郁和养育方式。
Objectives. This study examined the ways in which body mass index (BMI) percentile an identified risk factor for overweight and cardiovascular disease in adulthood develops from birth through early adolescence. In addition, we examined whether psychosocial factors, such as parenting style and maternal depression, mediated the link between socio-economic status (SES) and BMI growth.Design. Data were obtained from phases 13 of the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development (SECCYD) a longitudinal study that followed children from 10 communities in the United States from birth to age 11.Methods. We applied growth mixture models to identify distinct subtypes of BMI development. Within these models, we performed between- and within-class mediation analyses to examine whether SES predicted class membership or differences in development within each class via maternal depression and parenting styles.Results. Results identified three prototypic trajectories of BMI percentile growth, elevated, steady increase, and stable. We found evidence for both between- and within-class mediation, suggesting multiple pathways by which SES can affect BMI development.Conclusions. These findings add to the research that suggests that being in a family with a low SES is associated with falling into patterns of development characterized by early and lasting increases in BMI relative to one's peers, and that this association is partly accounted for by maternal depression and parenting styles.
