The mean HbA1c values during pregnancy decreased significantly over time (all <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). The decreasing trends were associated with preterm delivery (<jats:italic>P<\/jats:italic>\u2009=\u20090.021) but not with other perinatal outcomes. The time trends were significantly different between patients with type 1 diabetes mellitus and with type 2 diabetes mellitus in large for gestational age (LGA) and stillbirth (both <jats:italic>P<\/jats:italic> for interaction &lt;0.05). The rate of LGA decreased among patients with type 2 diabetes (<jats:italic>P<\/jats:italic>\u2009=\u20090.003) but not those with type 1 diabetes (<jats:italic>P<\/jats:italic>\u2009=\u20090.413).
