The purposes of this study were to assess survival among triplets who are born to teen mothers and to determine whether fetal number influences the mortality rates of the offspring of teen mothers when compared with the offspring of older women. A retrospective cohort study of 354 triplet births to teenage mothers an d 6858 to young mature mothers (20-29 years) who were delivered from 1995 throu gh 1998. We compared the occurrence of stillbirth and neonatal and infant mortal ity rates between the 2 categories by means of the generalized estimating equati on. Similar analyses were conducted for singleton pregnancies and twin pregnanci es. Triplets of teenage mothers experienced a higher level of stillbirth (odds r atio, 3.24; 95%CI, 1.44-7.24), neonatal mortality (odds ratio, 2.00; 95%CI, 1 .11-3.61), and infant death (odds ratio, 1.66; 95%CI, 1.01-2.87). Moreover, a s the plurality increased from singleton infant to triplet, the offspring of tee nagers fared progressively worse (P <.0001). This study confirms the association between teenage motherhood and feto-infant death and indicates that this morta lity relationship varies in a dose-dependent fashion.
