      Household food insecurity is associated with self-reported pregravid weight status, gestational weight gain, and pregnancy complications.
      ) examine the association between household-level food insecurity and maternal pregravid weight status, gestational weight, and complications of pregnancy, particularly second-trimester anemia, pregnancy-induced hypertension, and gestational diabetes mellitus (GDM). Controlling for potential confounders in regression models, the investigators find the expected positive associations between food insecurity and pregravid severe obesity (body mass index ≥35), gestational weight gain, and adequacy of gestational weight gain ratio. Surprisingly, no statistically significant relationship was found between food insecurity and either inadequate or excessive gestational weight gain using the 1990 Institute of Medicine ranges of recommended gestational weight gain (

      ). As the authors suggest, this may be due to their use of self-reported pregravid weight for their calculation of body mass index and gestational weight gain.
