Spatial Distribution of Risk Factors Associated to Adolescent Mothers


Objective: To analyze the spatial distribution of risk factors associated with adolescent mothers.

Methods: Case-control study, with a sample of 279 cases (newborns <2, 500 g) and 558 controls (new borns ≥ 2, 500 g), collected from the Live Birth Information System. In the unadjusted analysis, Pearson's chisquare was used, with a descriptive value of p <0.20. In the adjusted multivariate model, p <0.05 was considered. In the spatial analysis, the distribution of points and Kernel density was used.

Results: The significant variables were: number of children born alive, weeks of gestation, number of prenatal consultations and type of pregnancy. In the spatial distribution, clusters were observed in regions of greater socioeconomic vulnerability.

Conclusions: The identification of risk factors for pregnancy in adolescence may indicate rapid and effective preventive strategies to avoid low birth weight.
