Fetal/Maternal-Determined Birth Weight and Adulthood Type 2 Diabetes and Its Subtypes: A Mendelian Randomization Study

Lower birth weight (BW) might increase the risk of adulthood type 2 diabetes, but its associations with the highly heterogeneous type 2 diabetes subtypes remain to be studied. In addition, whether the associations between lower BW and adulthood type 2 diabetes risks depend on fetal or maternal effect is largely unknown.
