Objective: To know the principal characteristics associated to adolescent pregnancy and value it as a possible risk factor for low birthweight. Materials and methods: To study cases and controls for six months. The cases were selected from nuliparous women aged from 14 years to 19 years admitted to obstetrics during labour. The controls, nuliparous women aged 20 years or more, were admitted to the same center during the same period of time and were chosen randomly from the admissions book. These were coded and later processed using the data of the SPSS V 11.0 programme; descriptive analysis of the data was made, OR was calculated as the measurement of association, with an CI of 95% and the Chi squared test as a contrast of the hypothesis, and assuming the value p < 0.05 to be the statistically significant difference between them. A multivariant analysis was also carried out using a multiple logistic regression model. Results: 242 cases and 484 controls. The risk factors associated with low birth weight identified in the analysis were: the age of the mother < 19 years OR 2.12; CI (1.30-3.44) and antenatal control < 5 visits, OR 5.15 (2.81-9.41). Generally speaking the adolescent mothers were out of the education system and mostly worked as domestic assistants, they also had a higher incidence of low birth weight and prematurity. Conclusions: There is an association between the age of the mother and low weight neonates, which increases amongst those who do not attend the antenatal clinics regularly. |
