Data
Data 1
Fish consumption by pregnant women [1] for twelve various fish species commonly consumed in Finland as normal distributions (mean, SD).
Data 2
Domestic fish consumption of the pregnant women include fish consumption data [2] for twelve different species and demonstrate five fractiles (0.05, 0.25, 0.5, 0.75 and 0.95). There are several species with zero consumption. These values are replaced with a very low value 1u=10-6 to avoid errors prompts in the further calculations of the model. In addition we use the estimated fish consumption of the general population [3], as a reference. D↷
Data 3
Consumption of sea and freshwater fish species by pregnant women was extracted from [4] where the summary statistics of intakes of twelve fish species by users only are given (mean, sd and percentiles: 5th,25th, 50th, 75th, 95th). The estimation process was basically broken down into three steps. In the first step fish intake distributions for fish users were determined based on data in [5]. Here, for a given species the starting/initial cumulative distribution function (CDF) of intake was first constructed by linear interpolation between known percentiles. In general, this distribution will not reproduce the mean and SD as provided by the data. Therefore, the constrained optimization was further used to find the CDF that satisfies the percentiles given and whose mean and variance are as close as possible to the mean and variance from the data. In the second step the intake distributions for all pregnant women were determined. This was possible thanks to information about the percentage of pregnant women consuming particular fish species. Finally, species specific data on the sea and inland intake proportions (extracted from [6]) was used to estimate the intake of sea and freshwater fish species by all pregnant women.
