  • Data are means ± SD or n (%). All women with known preexisting diabetes were excluded. Women were characterized into three mutually exclusive PCOS categories: having a PCOS diagnosis any time prior to delivery, having a diagnosis of PCOS symptoms (oligo/amenorrhea, ovulatory dysfunction, hyperandrogenism, or hirsutism) but without a PCOS diagnosis, and having no diagnosis of PCOS or PCOS symptoms. The race/ethnicity pattern of higher rates of GDM among Asians and Hispanics and lower GDM rates among whites and blacks was similar across the PCOS categories (data not shown).
