Background/Objectives: The mother is an important mediator to the infant of polyunsaturated fatty acids (PUFA), the essential constituents of membranes particularly in the brain and retina. We here aimed in a prospective study initiated in early pregnancy to establish whether serum fatty acid (FA) compositions and concentrations in the mother can be modified by dietary means emphasizing counseling on a recommended diet. Subjects/Methods: Ninety women in the first trimester of pregnancy were randomized into intervention (n=45) or control (n=45) groups. The intervention comprised individual dietary counseling advocating choice of foods that will increase the intake of unsaturated and reduce that of saturated FA. To support this, appropriate products, including spreads, were provided for consumption at home. Dietary intakes were measured from food records and serum phospholipids, cholesteryl esters and triacylglycerols FA were analyzed by gas chromatography. Results: Dietary counseling resulted in lower intake of saturated and higher intake of unsaturated FA compared with the controls. These changes were reflected in higher proportions of serum phospholipid PUFA (mean difference between groups 0.61% (95% confidence interval, CI 0.05-1.17), P=0.03), docosahexaenoic acid (0.5% (0.15-0.85), P=0.01), sum of n-3 FA (0.61% (0.07-1.15), P=0.03) and lower ratio of n-6/n-3 FA (-0.42% (-0.81-0.03), P=0.03) in the intervention group at the third trimester of pregnancy but not at 1 month postpartum. Similar changes were seen in the FA of cholesteryl esters and triacylglycerols. Conclusion: Maternal serum n-3 FA status during pregnancy can be improved by dietary means emphasizing the importance of dietary advice. Copyright © 2013 Macmillan Publishers Limited.

Fetal conditions are known to be partly responsible for the childs risk for obesity. Our pilot study aimed to determine the effect of gestational lifestyle counseling on the offspring weight gain until 4 years of age and to estimate power for future studies.First-time pregnant mothers participated in a controlled trial conducted in maternity health clinics during 2004 - 2006. The intervention included individual counseling on physical activity and diet, and an option to attend supervised group exercise sessions. The participant mothers (N=109) received a follow-up questionnaire concerning 13 repeated growth measurements of their offspring. Response rate to the follow-up questionnaire was 66.1% (N=72/109).The increase of BMI z-score between 24-48 months was not significantly slower among the intervention group offspring (95% CI -0.025 to 0.009, p=0.34) compared to control group. Z-scores for weight-for-length/height did not differ between groups when the period 0-48 months was analyzed (95% CI -0.010 to 0.014, p=0.75).In this pilot study gestational lifestyle counseling did not significantly slow the weight gain of the offspring. Gestational intervention studies with at least 300 mothers per group are needed to confirm the possible effect on offsprings risk for obesity.Current Controlled Trials ISRCTN21512277.
