Data are means and standard error from linear mixed models with repeated adiposity measurements, adjusted for sex, race/ethnicity, age, pubertal status, age × pubertal status.
Interaction p-value refers to the interaction of GDM exposure with each health behavior (for example, breastmilk months category × GDM exposure).
