ABSTRACT
Various studies have focused on breastfeeding and the possible factors associated with early weaning. This study aimed to identify risk factors and protective factors for duration of breastfeeding in low-income families in southern Curitiba, Paraná State, Brazil. A cohort study from November 2006 to March 2007 included 118 mothers of children less than two years of age and enrolled in the TC Health Unit (USTC) located in the southern area of Curitiba. Statistical analyses using the Kaplan-Meier method and Cox regression model identified the following protective factors for breastfeeding: mother's awareness of the benefits of extended breastfeeding, exclusive feeding with mother's breast milk while in the maternity ward, and rooming-in. Factors contributing to early weaning were low birth weight, mother's work outside the home, and difficulties experienced by the mother in breastfeeding during the first days postpartum.

O aleitamento materno e os possíveis fatores associados ao desmame precoce têm sido alvos de diversos estudos. Este trabalho teve como objetivo identificar, em famílias de baixa renda da região sul de Curitiba, Paraná, Brasil, fatores de risco ou de proteção associados à duração do aleitamento materno. Um estudo de coorte foi conduzido entre novembro de 2006 e março de 2007 com 118 mães de crianças menores de dois anos de idade com vínculo na Unidade de Saúde TC (USTC), localizada na região sul de Curitiba. Análises estatísticas realizadas com o auxílio do método de Kaplan-Meier e do modelo de regressão de Cox apontaram como fatores protetores do aleitamento materno: a consciência da mãe sobre os benefícios da amamentação por tempo estendido, a amamentação da criança com leite exclusivamente materno na maternidade e o alojamento conjunto da mãe e criança na maternidade. Por outro lado, o baixo peso da criança ao nascimento, o trabalho da mãe fora de casa e as dificuldades encontradas pela mãe para amamentar nos primeiros dias pós-parto foram fatores apontados como contribuidores do desmame precoce.
