Pregnancy and Birth to 24 Months Systematic Review

Systematic Review Question

What is the relationship between dietary patterns before and during pregnancy and gestational age- and sex-specific birth weight?

Conclusion Statement

No conclusion can be drawn on the association between dietary patterns during pregnancy and birth weight outcomes. Although research is available, the ability to draw a conclusion is restricted by 

  • inconsistency in study findings,
  • inadequate adjustment of birth weight for gestational age and sex, and
  • variation in study design, dietary assessment methodology, and adjustment of key confounding factors.

Grade: Grade not assignable

Insufficient evidence exists to estimate the association between dietary patterns before pregnancy and birth weight outcomes. There are not enough studies available to answer this question.

Grade: Grade not assignable
