Draft Conclusion Statement

The draft conclusion statements listed below describe the state of the science related to the specific question examined. Draft conclusions are not considered final until they have been deliberated with and decided upon by the full Committee and published in the Committee’s final advisory report. Individual conclusion statements should not be interpreted as dietary guidance or the Committee’s overarching advice to the Departments. 

Developmental domains

Cognitive development: Moderate evidence indicates that seafood intake during pregnancy is associated favorably with measures of cognitive development in young children. Grade: Moderate

Language and communication development: Limited evidence suggests that seafood intake during pregnancy may be associated favorably with measures of language and communication development in the child. Grade: Limited

Movement and physical development: Insufficient evidence is available to determine the relationship between seafood intake during pregnancy and movement and physical development in the child. Grade: Grade Not Assignable

Social-emotional and behavioral development: Insufficient evidence is available to determine the relationship between seafood intake during pregnancy and social-emotional and behavioral development in the child. Grade: Grade Not Assignable

Attention deficit disorder or attention deficit/hyperactivity disorder-like traits or behaviors

Insufficient evidence is available to determine the relationship between seafood consumption during pregnancy and attention deficit disorder or attention-deficit/hyperactivity disorder-like traits or behaviors in the child. Grade: Grade Not Assignable

Attention deficit disorder or attention deficit/hyperactivity disorder diagnosis

No evidence is available to determine the relationship between seafood consumption during pregnancy and diagnosis of attention deficit disorder or attention-deficit/hyperactivity disorder. Grade: Grade Not Assignable

Autism spectrum disorder 

Insufficient evidence is available to determine the relationship between seafood consumption during pregnancy and autism spectrum disorder-like traits or behaviors or autism spectrum disorder diagnosis in the child. Grade: Grade Not Assignable
