OBJECTIVE To identify independent risk factors for non-breastfeeding within the first hour of life.METHODS A systematic review of Medline, LILACS, Scopus, and Web of Science electronic databases, till August 30, 2013, was performed without restrictions on language or date of publishing. Studies that used regression models and provided adjusted measures of association were included. Studies in which the regression model was not specified or those based on specific populations regarding age or the presence of morbidities were excluded.RESULTS The search resulted in 155 articles, from which 18 met the inclusion criteria. These were conducted in Asia (9), Africa (5), and South America (4), between 1999 and 2013. The prevalence of breastfeeding within the first hour of life ranged from 11.4%, in a province of Saudi Arabia, to 83.3% in Sri Lanka. Cesarean delivery was the most consistent risk factor for non-breastfeeding within the first hour of life. “Low family income”, “maternal age less than 25 years”, “low maternal education”, “no prenatal visit”, “home delivery”, “no prenatal guidance on breastfeeding” and “preterm birth” were reported as risk factors in at least two studies.CONCLUSIONS Besides the hospital routines, indicators for low socioeconomic status and poor access to health services were also identified as independent risk factors for non-breastfeeding within the first hour of life. Policies to promote breastfeeding, appropriate to each context, should aim to reduce inequalities in health.
Resumo O objetivo do trabalho foi analisar os fatores associados com o início tardio da amamentação (não amamentar na primeira hora de vida). Estudo transversal conduzido em 2009 com 673 puérperas internadas em hospitais do Sistema Único de Saúde (SUS) do Município do Rio de Janeiro, Brasil. Um modelo de regressão logística multinível com dois níveis (individual e hospitalar) foi utilizado nas análises estatísticas. A prevalência de início tardio da amamentação foi de 49,2%. O parto em Hospital Amigo da Criança (HAC) teve um efeito protetor contra o atraso no início da amamentação (OR = 0,17; IC95%: 0,05-0,55), enquanto a cesariana (OR = 5,95; IC95%: 3,88-9,12) e o desconhecimento do resultado do exame anti-HIV até o parto (OR = 2,16; IC95%: 1,04-4,50) aumentaram a chance de atraso. Redução das taxas de cesariana, adesão aos protocolos de atenção pré-natal e ampliação do credenciamento dos hospitais como HAC são estratégias importantes para promover o aleitamento materno na primeira hora de vida.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
