'''Fish oil intake in Beneris''' describes exposures of omega-3 fatty acids due to fish consumption in the [[Benefit-risk assessment of fish consumption for Beneris#Beneris population|Beneris population]].
What is the '''fish oil''' (omega-3 fatty acids due to fish consumption) intake in the [[Benefit-risk assessment of fish consumption for Beneris#Beneris population|'''Beneris''' population]]?


== Definition  ==
== Definition  ==
Fish oil intake is represented as a continuous variable and is indexed by variable age. It applies to Finnish pregnant women (this represents prenatal exposure to fish oils from fish), to the two last age categories (18-55yr, 55yr+) and to indicators such as intelligence quotient (IQ) in children and the risk of CVD mortality in adults.

Data 2 represents intake of docosahexaenoic acid (DHA) by Finnish pregnant women due to fish consumption. The DHA intakes from sea and freshwater species are estimated separately. The DHA intake from a given fish species is calculated as a product of the DHA concentration in this species and intake of this species by pregnant women divided by the body weight of pregnant women.

'''Data 3'''
 
Data 3 provides intake of omega-3 fatty acids (docosahexaenoic acid (DHA) + eicosapentaenoic acid (EPA)) by Finnish adults due to fish consumption. Age groups of interest are 18-55yr and 55yr+. Intakes from sea and freshwater species are estimated separately.

'''Data 1'''
Fish oil intake is represented as a continuous variable. Exposure is calculated as a product of concentration data and fish consumption data. This is further divided by bodyweight to report exposure in relation to kg of bodyweight. The formula provides intake of omega-3 fatty acids (docosahexaenoic acid (DHA) + eicosapentaenoic acid (EPA)) due to fish consumption.

Scope

What is the fish oil (omega-3 fatty acids due to fish consumption) intake in the Beneris population?

Definition

Data

The variable is directly computed from other variables.

Dependencies

List of parents:

Unit

mg/kg bw/d

Formula

Fish oil intake is represented as a continuous variable. Exposure is calculated as a product of concentration data and fish consumption data. This is further divided by bodyweight to report exposure in relation to kg of bodyweight. The formula provides intake of omega-3 fatty acids (docosahexaenoic acid (DHA) + eicosapentaenoic acid (EPA)) due to fish consumption.

----1: . The formula for Data 1 was removed because the input variables are in g/d, not in kg/a. The formulas for Data 2 and Data 3 were merged, because the former is simply a special case of the latter. --Jouni 17:03, 16 September 2009 (EEST) (type: truth; paradigms: science: comment)

The old descriptions can be found from a previous version.


(DHA_Concentration_species(i)+EPA_Concentration_species(i))*Daily_consumption_species(i)/BW

Result

Note! The current version only estimates DHA (not EPA) intake for pregnant women (not other groups) in Finland. Intakes from sea and freshwater species are estimated separately.
