Gestational diabetes (GDM), a common pregnancy complication, affects different race/ethnicities disproportionally. Adult height, an indicator of both genetic and early-life factors, was inversely associated with GDM in most studies. The current study investigates the association of height with GDM risk and whether the association varies by race. The Consortium on Safe Labor (CSL) is an observational study capturing 135,861 deliveries (2005-2007), including 5,567 GDM cases. CSL data suggest height is significantly and inversely associated with GDM risk across race/ethnicities, with magnitude of association greatest in Asians and smallest in Blacks (p-value <0.001). Comparing extreme quartiles of height, the adjusted ORs (95% CI) were 0.19 (0.10-0.38) for Asians, 0.35 (0.30-0.40) for Whites, 0.42 (0.33-0.55) for Hispanics, and 0.59 (0.47-0.76) for Blacks. Additionally, a meta-analysis of 15,761 women with GDM and 205,828 without from 38 studies found GDM women were significantly shorter than non-GDM women across race/ethnicity groups except among Black women.
