This study aims to estimate the adolescent fertility rates in Brazil and regions, providing the time trend, between 2008 and 2017. This is an ecological study of time series. The data were collected from the Live Birth Informational System (SINASC) and the Department of Informatics of the Unified Health System (DATASUS). The time trend of the adolescent fertility rates was calculated using polynomial regression, with a significance level of 5%. For all years studied and all age groups (10 to 19, 10 to 14, and 15 to 19 years old), the North, Northeast, and Midwest regions showed higher rates than Brazil, whereas the South and Southeast regions had lower rates than national. The Northern region had the highest fertility rates, varying from 103.2 per 1,000 adolescent women in 2008 to 80.9 per 1,000 adolescent women in 2017, for the aged 15-19 years. Brazil and other regions showed a significant decreasing trend in fertility rates for all age groups. However, the rates remain high, particularly in the North and the Northeast regions. We emphasize the necessity of specific actions towards adolescents, considering the regional differences and the equity in health care.
