title: Does docosahexaenoic acid (DHA) status in pregnancy have any impact on postnatal growth? Six-year follow-up of a prospective randomized double-blind monocenter study on low-dose DHA supplements.
abstract: Fetuses and breastfed children depend on the maternal docosahexaenoic acid (DHA) supply, which might have long-lasting consequences. We studied the growth of 6-year-old children whose mothers received supplemental DHA from midpregnancy to 3 months after delivery. One hundred and forty-four pregnant women had been randomized to receive one of three vitamin-mineral supplements, one supplying an additional 200 mg/day DHA. Of the original sample, 120 children were measured at age 6 years with standardized methods. As one objective of the follow-up was to investigate the DHA influence on normal growth, the DHA group was compared with the pooled controls after exclusion of five premature infants. The weight, length, body mass index (BMI), head circumference, and skin-fold thickness at 6 years were similar in the 41 children of the DHA group and the 74 controls. Longitudinally, the BMI z-scores of the DHA group increased up at a later age than that of the controls. We found a highly significant negative correlation between height at 6 years and the increase in red blood cell DHA concentration of mothers from 22 to 37 weeks of pregnancy. We conclude that DHA supplements during midpregnancy corrected a low maternal DHA status (which correlated with children's height) and was favorable in regard to the BMI development up to 6 years.
