RESUMO
Resumo Avaliar os fatores associados ao consumo de leite materno (LM), fórmulas lácteas (FL) e leite de vaca (LV). Estudo de coorte com 247 crianças acompanhadas no 1°, 4° e 6° mês de vida, em Viçosa-MG. Para o LV e FL contabilizouse o consumo independentemente da ingestão de LM. Para o LM, considerou-se apenas o consumo exclusivo ou predominante. Do 1° ao 6° mês observou-se o aumento do não consumo de LM de forma exclusiva ou predominante (31,6%), bem como do consumo de LV (27,2%) e FL (9,3%). O LM associou-se ao uso de chupeta no 1° mês, e ao trabalho materno e uso de chupeta no 4° e 6° mês. O uso de chupeta foi fator de risco para o consumo de FL em todos os meses, enquanto pertencer ao grupo de menor renda foi inversamente associado no 6° mês. Para o LV, o número de consultas pré-natal foi fator de risco em todos os meses, o trabalho materno e o uso de chupeta no 4° mês, a renda familiar, trabalho materno, baixo peso ao nascer, número de consultas pré-natal e uso de chupeta no 6° mês. Desde o 1° mês a introdução de outros tipos de leite é elevada, revelando que ainda há muito a se percorrer para a garantia do aleitamento materno exclusivo até os 6 meses.
Abstract This study evaluated factors associated with the consumption of breast milk (BM), infant formula (IF) and cow milk (CM) in children. This was a cohort study with 256 children followed-up at the 1st, 4th and 6th month of age in Viçosa (MG), Brazil. With respect to CM and IF, consumption was recorded regardless of BM intake. Regarding BM, only exclusive or predominant consumption was considered. From the 1st to the 6th month, an increase was recorded in the number of children who did not consume BM exclusively or predominantly (31.6%), as well as the consumption of CM (27.2%) and IF (9.3%). BM was associated with pacifier use at 1st month, and mother's employment status and pacifier use in the 4th and 6th month. Pacifier use was a risk factor for IF consumption in every month, while belonging to the lower income group was inversely associated in the 6th month. As for CM, the number of prenatal visits was a risk factor in every month, the mother's employment status and use of pacifier in the 4th month, family income, mother's employment status, low birth weight, number of prenatal visits and pacifier use in the 6th month. Since the 1st month, the introduction of other milk types is high, revealing that there is still much to go to ensure exclusive breastfeeding up to 6 months.
