Reduced docosahexaenoic acid synthesis may contribute to growth restriction in infants bornto mothers who smoke

In newborn infants, progressive decrease in anthropometric values and impairment of the docosahexaenoic acid (DHA) status was associated with maternal smoking during pregnancy, with a parallel increase of the metabolic precursor of DHA, alpha-linolenic acid. Maternal smoking may impair DHA synthesis which may contribute to reduced fetal growth.
