Systematic Review Question

What is the relationship between omega-3 fatty acids from supplements consumed before and during pregnancy and lactation and developmental milestones, including neurocognitive development, in the child?

Conclusion Statement

Pregnancy
Limited evidence suggests that omega-3 fatty acid supplementation during pregnancy may result in favorable cognitive development in the child. (Grade: Limited)

Insufficient evidence is available to determine the relationship between omega-3 fatty acid supplementation during both pregnancy and lactation, or during pregnancy only, and language and social emotional development in the child. (Grade: Grade not assignable) 

Insufficient evidence is available to determine the relationship between omega-3 fatty acid supplementation during pregnancy and motor and visual development, academic performance, and the risk of attention-deficit disorder, attention-deficit/hyperactivity disorder, and autism spectrum disorder in the child. (Grade: Grade not assignable)

No evidence is available to determine the relationship between omega-3 fatty acid supplementation during both pregnancy and lactation, or during pregnancy only, and anxiety or depression in the child. (Grade: Grade not assignable)

Insufficient evidence is available to determine the relationship between omega-3 fatty acid supplementation during both pregnancy and lactation and cognitive development in the child. (Grade: Grade not assignable)

No evidence is available to determine the relationship between omega-3 fatty acid supplementation during both pregnancy and lactation and visual development, academic performance, or the risk of attention-deficit disorder, attention-deficit/hyperactivity disorder, or autism spectrum disorder in the child. (Grade: Grade not assignable)

Lactation
Insufficient evidence is available to determine the relationship between omega-3 fatty acid supplementation consumed during both pregnancy and lactation or during lactation alone, and cognitive, language, motor, and visual development in the child. (Grade: Grade not assignable)

No evidence is available to determine the relationship between omega-3 fatty acid supplementation consumed during both pregnancy and lactation or during lactation alone and academic performance, anxiety, depression, or the risk of attention-deficit disorder, attention-deficit/hyperactivity disorder, or autism spectrum disorder in the child. (Grade: Grade not assignable)

No evidence is available to determine the relationship between omega-3 fatty acid supplementation consumed during lactation and social-emotional development in the child. (Grade: Grade not assignable)
