PURPOSE The relationship between docosahexanoic acid (DHA) intake of supplemented (+S) and non‐supplemented (‐S) pregnant women living in Iowa (IA) and Montana (MT) and DHA blood values was examined. METHODS Intake with 79 pregnant women (36 –S/IA, 20 –S/MT, 14 +S/IA, 9 +S/MT) was determined through a novel food frequency questionnaire (FFQ) designed to assess episodic intake of foods containing DHA. Blood DHA was determined through HPLC and expressed as the percentage of DHA to other fatty acid species in the blood. Results were tested using ANOVA and post hoc tests with a Bonferroni correction. Values are mean ± SD. RESULTS Locale and supplementation significantly affected intake (MT > IA, +S > ‐S, in mg DHA/day): ‐S/IA = 42 ± 65, +S/IA = 283 ± 142, ‐S/MT = 138 ± 122, +S/MT = 366 ± 139, P < 0.0001 ± supplement, P < .0005 IA vs MT. Phosphatidylethanolamine (PE) fractions were significantly different when comparing supplementation or locale, whether or not DHA intake was used as a covariate (in % DHA): ‐S/IA = 3.45 ± 1.10, +S/IA = 3.93 ± 1.09, ‐S/MT = 4.21 ± 1.04, +S/MT = 4.83 ± 1.05, P < 0.05 ± supplement, P < .005 IA vs MT. DHA intake was significant as a covariate (P < 0.0005). CONCLUSION There was differential intake by location and supplement use, and while there were significant differences in DHA blood values they showed less response than expected considering past literature.
