Associated factors to spatial variation of pregnancy in adolescence in Brazil, 2014: ecological study of spatial aggregates




Adolescent Pregnancy, Spatial Analysis, Socioeconomic Factors, Primary Health Care


Objective. To identify socioeconomic and health care determinants of the spatial variation of teenage pregnancy in Brazil in 2014. Methods. Spatial ecological study with municipalities as units of analysis. Spatial linear regression was used to verify the association between fertility in adolescence (15-19 years) and socioeconomic and health variables. Results. Fertility rate in adolescence was negatively associated with greater coverage of the Family Health Strategy (β = -0.011 – 95%CI -0.017;-0.005), an adequate number of prenatal consultations (β = -0.122 – 95%CI -0.132;-0.224) and low per capita average family income (β = -0.104 – 95%CI -0.105;-0.103). This association was positive in relation to the Gini index (β = 7.031 – 95%CI 95%CI 4.793;9.269), low income (β = 0.127 – 95%CI 0.108;0.145), household crowding (β = 6.292 – 95%CI 5.062;7.522) and less education (β = 0.260 – 95%CI 0.224;0.295). Conclusion. Lack of access to primary care and lower income are associated with higher fertility in adolescence. Worse socioeconomic and health care indicators are associated with higher fertility rate in adolescence.
