Abstract Objectives: to investigate the factors associated with continued breastfeeding (BF). Methods: All the parturients at a local maternity from July 2015 to June 2016 were invited to participate in a cohort study in Cruzeiro do Sul, Acre. Data on socioeconomic, demographic, obstetric and neonatal of the babies were obtained for the interview. Multiple Poisson regression models with robust variance were used to estimate the prevalence ratio (PR) and 95% confidence intervals (95%CI). Results: among the 1551 mothers contacted, 305 lived in the rural area, leaving 1,246 eligible mothers living in urban area. For the 1-year cohort follow-up, 74 non-twin babies were assessed. Most of the mothers reported to have mixed skin color (79%), are over 21 years old (72°%o), more than 10 years of schooling (72%>) and with unpaying job (54%). The children’s age ranged from 10 to 15 months. The frequency of continued breastfeeding was 69,4%> (95%oCI=66.0-72.6). The factors negatively associated with continued breastfeeding were the use of bottle feeding (PR=1.44; CI95%> =1,33-1.56) and pacifier (PR=2.54; CI95%> =1.98-3.27), after adjusting for maternal age and socioeconomic variables. Conclusion: the frequency of continued breastfeeding in Cruzeiro do Sul was higher than the national estimates, but below the WHO recommendations for breastfeeding up to two years of age. Resumo Objetivos: investigar frequência e fatores associados ao aleitamento materno (AM) continuado. Métodos: estudo de coorte em Cruzeiro do Sul, Acre. Na maternidade, todas as parturientes de julho de 2015 a junho de 2016 foram convidadas à participação. Dados socioeconómicos, demográficos, obstétricos e neonatais dos bebês foram obtidos por entrevista. As razões de prevalência (RP) e intervalos com 95% de confiança (IC95%) foram estimados utilizando modelos múltiplos de regressão de Poisson com variância robusta. Resultados: dentre 1551 mães contatadas, 305 residiam em área rural, sendo elegíveis 1246 mães residentes em área urbana. No seguimento de 1 ano da coorte, 774 bebês não gemelares foram avaliados. A maioria das mães referiu ser de cor parda (79%o), maior de 21 anos (72%), >10 anos de escolaridade (72%) e não exercer atividade remunerada (54%). A idade dos bebês variou de 10 a 15 meses. A frequência do AM continuado foi de 69,4%o (IC950%= 66,0-72,6). Os fatores inversamente associados ao AM continuado foram uso de mamadeira (RP= 1,44; IC95% 1,33-1,57) e chupeta (RP= 2,55; IC95%= 1,99-3,28), a
