| Popis: | ObjectivesTo assess dietary fatty acid intakes and to examine the relationship between dietary sources ofn-3 andn-6 PUFA and red-blood-cell (RBC)n-3 andn-6 PUFA composition.DesignA cross-sectional study. Dietary intakes were assessed with a 24 h dietary recall. A second recall was performed for 44 % of the children. Usual dietary intakes were estimated with the Software for Intake Distribution Estimation (SIDE). The fatty acid composition was measured in RBC membranes. Multivariate linear regression analyses were performed to explain RBCn-3 andn-6 PUFA concentrations.SettingChild-care centres in Nunavik, northern Québec, Canada.SubjectsOne hundred and sixty-seven Inuit children aged 11–53 months.ResultsA high proportion of the participants had inadequaten-3 andn-6 PUFA intakes (47·9 % and 93·5 %, respectively). Breast-feeding status and consumption of traditional food during the first 24 h dietary recall were significantly associated with RBCn-3 PUFA levels. Older children also tended to have higher RBCn-3 PUFA levels (P= 0·0528), whereas sex, infant formula status andn-3 PUFA dietary intakes were not associated with RBCn-3 PUFA concentrations. RBCn-6 PUFA concentrations were positively associated with breast-feeding status andn-6 PUFA dietary intakes, whereas age, sex and infant formula status were not.ConclusionsThe present findings highlight the fact that Inuit pre-school children are not consuming enoughn-3 andn-6 PUFA for optimum health. These observations call for actions to increase traditional food intake among Inuit children and to help them and their parents make healthier store-bought food choices. |
