Objective: Docosahexaenoic acid (DHA) is an important nutrient required by pregnant women and fetuses. Several studies suggest that fatty acid composition changes during pregnancy. However, the association of longitudinal changes in erythrocyte fatty acid composition and dietary fatty acid intake during pregnancy is not well understood. We assessed the relationship between fatty acid composition of the erythrocyte membranes and fatty acid intake at each trimester in pregnant Japanese women. Methods: We conducted a prospective hospital-based cohort study. We investigated fatty acid composition of the erythrocyte membranes and intake of fatty acids during the three trimesters in 178 healthy, pregnant Japanese women. Results: The eicosapentaenoic acid and arachidonic acid percentage of the erythrocyte membranes significantly decreased. The percentages of linoleic acid and α-linolenic acid significantly increased during pregnancy. The DHA percentage in the erythrocyte membranes decreased from the second to the third trimester. The DHA percentage in the erythrocyte membranes positively correlated with DHA intake in the third trimester. Conclusion: In pregnant Japanese women, the fatty acid composition of the erythrocyte membranes markedly changed throughout pregnancy. The DHA intake in the third trimester may be insufficient to maintain DHA percentage in the maternal erythrocyte membranes.

Study Results

Background: Term infants can be categorized into 3 sub-groups: early term (37w0d to 38w6d), full term (39w0d to 40w6d), and late term (41w0d and beyond). However, the fatty acid composition among the 3 groups of term infants has not been investigated. The association between fatty acid composition and gestational period of term infants in Japan is unclear. Methods: We assessed the fatty acid composition of maternal erythrocyte membranes in the third trimester and of cord erythrocyte membranes at birth in 212 healthy term Japanese infants using data from a prospective hospital-based cohort study. Results: In maternal erythrocyte membranes, docosahexaenoic acid (DHA) levels and omega-3 index were significantly higher in the late-term group than in the early-term group. In cord erythrocyte membranes, DHA levels were not significantly different between the 3 groups; late-term infants showed significantly higher DHA/arachidonic acid (ARA) and lower 20: 3n-6 and ARA levels compared to early-term infants. Gestational period positively correlated with the DHA status in maternal and cord erythrocyte membranes. Conclusions: Fatty acid composition in maternal and cord erythrocyte membranes varies between early-, full-, and late-term infants, and the greater gestational period may contribute to the relatively high n-3 polyunsaturated fatty acids status in term infants. Furthermore, maternal DHA status in the third semester directly correlates with gestational period in pregnant Japanese women.

Dietary Fatty Acid Intake

AbstractObjectiveThe estimation of dietary intake in population-based studies is often assessed by the FFQ. The objective of our study is to evaluate the validity of an FFQ used to assess dietary fatty acid intake among middle-aged Chinese adults in Southern China.DesignThe method of triads was applied to obtain the validity coefficients (VC) of the FFQ for specific fatty acids. A subsample was randomly selected from an earlier cross-sectional study. The FFQ and 3d dietary records were used for dietary assessment, and the fatty acid composition of erythrocyte membranes was determined as the biomarker.ResultsThe Spearman correlation coefficients between the FFQ and 3d dietary records were moderate to good (r = 0·28–0·66). The VC of the FFQ estimated by the method of triads were 0·72, 0·61, 0·65, 0·75 and 0·67 for MUFA, total n-6 fatty acids, α-linolenic acid, EPA and DHA, respectively. The VC could not be calculated for SFA, PUFA and total n-3 fatty acids because of negative correlations among the three measurements. But, the correlations between the FFQ and the dietary records were moderate for these fatty acids.ConclusionsOur FFQ applied in Southern Chinese adults was valid to estimate their dietary fatty acid intake and was thus suitable for use in a large cohort study.
