Outcome of teenage pregnancy in St. Vincent: neonatal outcome and adequacy of milk from teenage mothers

ABSTRACT

In a longitudional study, pregnancy, neonatal outcome and lactation performance of adolescent and adult primigravidae were examined and compared in 33 randomly selected women (14-25 years) in St. Vincent. The whole group of women were subdivided into three sub-groups Group I (n=10, age 14-16 years), Group II (n=12, age 17-18 years), and Group III (n=11, age 19-25 years). Detailed data on obstetrical and neonatal (neurological) outcome were collected. After birth, information was obtained on early infant growth, maternal dietary intake and breast milk composition. Milk samples (transitional and mature milk) and maternal dietary information and neonatal anthropometric measurements were collected twice during the first month after birth through home visits. Between the 3 groups no significant differences in obstetric conditions, birthweight and early infant growth were found. The Neurological Optimality Score (NOS) was comparable for all groups, but a trend of more infants diagnosed as neurologically "suspect" infants in the younger age group shows the urgent need for more research in this field. Regarding the analysis of breastmilk samples, apart from lactose content, no major differences in the composition of macro-nutrients were found. Concerning the fatty acid composition of the milk fat, no major differences between the groups occurred, although a small number of individual fatty acids were different between the groups. Early infant growth patterns were similar in all groups. It is concluded that previously reported perinatal problems of healthy teenage primigravidae (14-16 years) were not substantiated fully in this series but neonatal outcome of infants of these mothers suggests that careful developmental follow-up of these children is indicated (AU)
