Introduction: Adolescent pregnancy is a social problem not solved in developing countries or some developed countries. It has been demonstrated that maternal age represents a risk factor in neonates with an increase in the prevalence of perinatal complications and psychomotor delay. Objectives: To compare neonatal neurological assessment and development in children born from adolescent mothers with those from non-adolescent mothers. To know their prenatal and perinatal history and to determine the frequency of cerebral palsy (CP) and delayed psychomotor development (DPD). Methods: Multicenter, retrospective, analytical, comparative cohort study of newborns and infants. The sample was randomly selected from clinical charts of 75,951 mothers in the puerperium, and the files of their newborns were analyzed for their neonatal neurological assessments. In total, 2,739 mothers 12 to 27 years old were assessed, of which 1,274 had 12 to19 years old (adolescents), and 1,465 had 20 to 27 years old (non-adolescents). Their infants were assessed from 0 to 4 months corrected age (m) with Neo Neuro and Up (NN&Up), and at 6 to18 (m) with Hammersmith evaluation (HINE) over a four-year period. Results: 1,274, (46.5%) were adolescent mothers (AM), and 1,465, (53.5%) were non-adolescent mothers (NAM). Initially, 2,739 NN&Up evaluations were performed in which 318 (11.6%) had abnormal results 10.9% in AM and 12.2% in NAM. At 6 to 18 m, 1161 HINE evaluations were performed, of which 2.7% were abnormal. 2.2% in AM, and 3.2% in NAM with clinical data of delayed psychomotor development. At the end of follow-up, 13 (0.47%) children were found to have DPD (0.23%) in AM and (0.68%) in NAM. At the end of study 13 (0.47%) children had DPD, 0.23% in AM and 0.68% in NAM. Moreover 9 children were diagnosed clinically and with neuroimaging with CP, 6 from AM and 3 from NAM. Conclusions: Children of AM in public hospitals in northeastern Mexico are born in frank vulnerability, particularly those of teen mothers. Their developmental assessments show a higher frequency of delayed psychomotor development in children of NAM and a higher frequency in children with CP in AM.
