Background: Nausea and vomiting are experienced by a majority of pregnant women worldwide. Previous studies\nhave yielded conflicting results regarding their impact on birth outcomes and few studies have examined this\nrelationship in settings with limited resources. We aimed to determine the effect of nausea, vomiting and poor\nappetite during pregnancy on birth outcomes in rural Nepal.\nMethods: Observational cohort study using data collected in two randomized, community-based trials to assess\nthe effect of influenza immunization during pregnancy on reproductive and respiratory outcomes among pregnant\nwomen and their offspring.

Exposure\nwas defined as nausea, vomiting or poor appetite at any point during pregnancy and by trimester; symptoms were\nrecorded monthly throughout pregnancy. Adverse outcomes were low birth weight (LBW), preterm birth and small\nfor gestational age (SGA). Adjusted relative risks (aRR) with 95% CIs are reported from Poisson regressions with\nrobust variance......................
