title: Lipid intake during pregnancy in developing countries: possible effect of essential fatty acid deficiency on fetal growth.
abstract: There is a strong epidemiological association between poor nutritional status and low-birthweight (LBW) newborns. According to the World Health Organization (WHO), 95% of total LBW in the world are born in developing countries. Nevertheless, the nutritional etiology of intra uterine growth retardation (IUGR) is still controversial and not yet established largely because of contradictory nutritional studies in pregnancy. In 1981 Menon et al described an animal model of IUGR due to mild deficiency in essential fatty acids (EFA, linoleic and alpha linolenic acids), with a strong correlation between EFA intake during pregnancy and fetal growth. According to the WHO reports in the last decade, there was a dramatic deficiency of lipid intakes (less than 10% of total caloric amounts) in the majority of developing countries while the EFA requirements alone of normal nourished women are evaluated at 6% of total caloric amounts during pregnancy. A mild deficiency in dietary EFA may be a limiting factor in fetal growth processes in humans as it has been shown in animals. Such a mechanism could be easily verified. Research proposals are made in an attempt to test this hypothesis in developing countries with possible applications in further nutritional interventions in pregnancy.
