Scope
What is the exposure-response function (ERF) of omega-3 fatty acids on intelligence quotient, measured as prenatal exposure to omega-3 fatty acids and intelligence quotient (IQ) score in children.
Definition
Data
The study by Cohen et al. 2005 [1] estimates that increasing maternal docosahexaenoic acid (DHA) intake by 100 mg/day increases child's IQ by 0.13 points D↷. This value represents central estimate while the upper and lower bound for this ERF is 0.08 and 0.18. Triangular distribution is used.
Dependencies
None defined.
Unit
IQ points/(100mg omega-3/d)
