Abstract：The aim of this paper is to investigate the effects of maternal clinical and physical characteristics on fatty acids composition in preterm milk, and to further support the possibility that fatty acids in breast milk may can diagnose or prevent preterm diseases. Brest milk samples (4±3, 11±3, 30±3, 60±3 and 90±3 days post-partum) were collected from 59 healthy women delivering preterm infants. Fatty acids composition in milk was determined with GC and was further analyzed with statistical software. The fat content in breast milk raised first and then decreased with the development of lactation period during 3 month after delivery. And the fatty acids composition in preterm milk was affected by maternal clinical and physical characteristics, including lactation, gestation, pre-pregnancy BMI, height and age, but has little relevance to maternal weight gain during pregnancy, parity and delivery mode.
