INS and gestational diabetes: Type 1 diabetes (aOR 0.35, 95%CI:0.27 to 0.45, p < .001), type 2 diabetes (aOR 0.74, 95%CI:0.59 to 0.93, p < .05) and gestational diabetes treated with Insulin (aOR 0.83, 95%CI:0.78 to 0.87, p < .001), decreased the odds of SGA compared to women without these conditions.
