Given the availability of well-studied "anchor" chemicals within related chemical groups, this SEM supports the feasibility of class-based approaches to evaluate the association between phthalates, PFAS, phenols, and parabens and fetal growth. Further research on PCPs and fetal growth should address areas of uncertainty, including data gaps on potential effect modifiers, such as socioeconomic status.
Bommarito et al. (Sat,) studied this question.
