Abstract:

We have previously shown that prenatal maternal total n-3 long chain polyunsaturated fatty acid (LC-PUFA) concentrations and n-6:n-3 ratios along with methylmercury (MeHg) exposure have interrelated effects on psychomotor development index scores in children in the Seychelles (a high fish eating population). The aim of this study was to examine the dietary patterns and determinants of maternal and child LC-PUFA and MeHg status. Pregnant women and children at age five completed four day food diaries that were analyzed using WISP v.3.0 to generate food intake amounts. LC-PUFA and MeHg status were measured in the mothers and children. In order to connect the nutritional and exposure status from these biomarkers to eating behavior based on fish intake, clustering was performed on the food intake variables. This created six and four subgroups of dietary patterns in the mothers and children respectively. Shellfish consumption was positively associated with MeHg status in mothers but not children, while white fish consumption was positively associated with maternal n-6:n-3 ratio and negatively associated with DHA and total n-6 ratio in children.
