Maternal breastfeeding: indicators and factors associated with exclusive breastfeeding in a subnormal urban cluster assisted by the Family Health Strategy / Aleitamento materno: indicadores e fatores associados à amamentação exclusiva num aglomerado urbano subnormal assistido pela Estratégia de Saúde da Família

Abstract Objective: To describe and analyze indicators of feeding practices related to breastfeeding and factors associated with exclusive breastfeeding (EBF) in a subnormal urban cluster (slums) in Pernambuco, Brazil. Methods: Four breastfeeding indicators were used to interview mothers of children under 3 years of age. An inventory of the families' socioeconomic and environmental factors, maternal obstetric history, and basic health care access was undertaken. The sample consisted of all 310 children under the age of 3 years from Coelhos, PE, Brazil. Spearman's correlation was carried out, as well as crude and adjusted prevalence ratios for a final statistical model that showed associated factors with the main outcome at a level of 0.05. Results: The prevalence of breastfeeding in the first hour of life, exclusive breastfeeding up to 6 months, continued breastfeeding at 1 year, and continued breastfeeding at 2 years were 60.2%, 32.9%, 45.9, and 35.9%, respectively. A correlation was observed between start of pacifier use and duration of either exclusive (r s = 0.358 [p < 0.001]) or non‐exclusive breastfeeding (r s = 0.248 [p = 0.006]). Maternal age over 35 years (p < 0.001), home visit in the first week after birth (p = 0.003), having had a male baby (p = 0.029), and not using a pacifier (p < 0.001) remained protective factors in the final model. Conclusion: The prevalence rates of exclusive breastfeeding at 6 months were well above the results obtained by other Brazilian authors. Home visit and maternal age prevailed as protective factors, while pacifier use was shown to be a discouraging practice.

Resumo Objetivo: Descrever e analisar indicadores das práticas relacionadas ao aleitamento materno e fatores associados ao aleitamento materno exclusivo em um aglomerado urbano subnormal (favela) em Pernambuco. Métodos: Foram usados quatro indicadores do aleitamento materno mediante entrevista com as mães de menores de três anos. Fez-se um inventário de fatores socioambientais das famílias, antecedentes obstétricos e acesso às ações básicas de saúde. A amostra inclui todas as 310 crianças da Comunidade de Coelhos, PE, Brasil. Feitas correlação de Spearman e razões de prevalências brutas e ajustadas que compuseram um modelo estatístico final que evidenciou os fatores associados ao principal desfecho ao nível de 0,05. Resultados: A prevalência do aleitamento materno na primeira hora de vida, aleitamento materno exclusivo aos 6 meses, amamentação continuada até um ano e dois anos foram, respectivamente, 60,2%, 32,9%, 45,9% e 35,9%. Na correlação entre o início do uso de chupeta e a duração do aleitamento, exclusivo ou não, obtiveram-se respectivamente os coeficientes rs = 0,358 (p < 0,001) e rs = 0,248 (p = 0,006). No modelo final permaneceram como fatores de proteção: a idade materna acima de 35 anos (p < 0,001), a visita domiciliar na primeira semana de vida (p = 0,003), o sexo masculino (p = 0,029) e o não uso da chupeta (p < 0,001). Conclusão: Os índices de prevalência do aleitamento materno exclusivo aos 6 meses foram bem superiores aos resultados obtidos por outras pesquisas nacionais. A visita domiciliar e a idade materna prevaleceram como fatores de proteção e o uso de chupeta como uma prática desestimulante.
