The aim of this study was to investigate n-3 and n-6 fatty acid status of pregnant women and neonates from River/Lake, Coastal and Inland regions of China. Demographic, nutritional and anthropometric data, as well as blood samples (maternal and cord) were obtained. Plasma choline phosphoglyceride (CPG) fatty acids were ana-lysed. Median daily fatty acid intakes of the women from River/Lake, Coastal and Inland women were linoleic acid (LA), 20.2, 22.1, 31.7 g; arachidonic acid (AA), 157.2, 95.6, 141.3 mg; a-linolenic acid (ALA), 4.2, 1.0, 1.8 g; eicosapentenoic acid (EPA), 22.4, 28.6, 3.1 mg; docosahexaenoic acid (DHA), 51.7, 54.7, 33.3 mg and the n-6 to n-3 fatty acid ratio, 4.7, 20.9, 17.2. The median maternal and cord plasma CPG AA levels of River/Lake, Coastal and Inland groups were 7.3% and 15.7%, 6.7% and 16.1%, and 7.2% and 16.9%. The median maternal and neonatal DHA levels in the three regions were 3.2% and 4.7%, 3.0% and 4.3%, and 2.0% and 3.6%. There appears to be a close association between dietary intake of AA, EPA, DHA and the corresponding levels of the fatty acids in maternal plasma CPG (p<0.05). The results of the study indicate low intake of the n-3 long chain polyunsaturated fatty acids, EPA and DHA, and n-6 to n-3 fatty acid imbalance are the main problems of dietary fat intake of Chinese pregnant women. Measures such as increased supply of oily fish and ALA-rich edible oils should be taken to help enhance n-3 fatty acid intake of pregnant Chinese women.
