vegetables, legumes, wholegrains). A one SD increase in the scores on the high protein/fruit pattern was associated with decreased likelihood of preterm birth (adjusted OR 0.31; 95%CI: 0.13, 0.72; p ¼ 0.007); whereas the high fat/sugar/take-away pattern was associated with increased risk for preterm birth (adjusted OR 1.54; 95%CI: 1.10, 2.15; p ¼ 0.011), and was also associated with shorter gestation (p ¼ 0.001) and birth length (p ¼ 0.004).

Poor dietary behaviours in the periconceptional period could be altered to promote behaviour change in dietary intake to improve perinatal outcomes and the long-term health of the child.

Background/Aims: In pregnancy partitioning of nutrients from maternal tissues to the foeto-placental unit ensures normal development of the foetus and is associated with decreased insulin sensitivity. Such changes can be influenced by diet and body condition. This study examined insulin and glucose responses in pregnant mares with disparate body condition Methods: Mares were given either a high (HE: n ¼ 6) or low energy (LE: n ¼ 7) diet for the last trimester of pregnancy. Body condition score (BCS) was assessed and a frequently sampled intravenous glucose tolerance test was performed on day 320 of gestation. This permitted determination of insulin sensitivity (Si), glucose effectiveness (Sg), acute insulin response to glucose (AIRg), and disposition index (DI). Results: The BCS in HE fed mares were significantly (p < 0.001) higher than LE fed mares. Insulin sensitivity, AIRg and DI were significantly (p < 0.01) lower in LE mares. In contrast, glucose effectiveness was not different. Conclusions: Overall the results indicate that LE fed mares became insulin resistant in late pregnancy and exhibit diminished b cell responsiveness; features characteristic of human GDM. This is the first report of equine GDM. These novel results highlight the importance of BCS in metabolic responses during pregnancy.
