Abstract
BACKGROUND: Breastfeeding is known to be the best source of nutrition for infants. The World Health Organization recommends to exclusively breastfeed up to the sixth month of life and to breastfeed with complementary foods until the age of 2. It is reported that maternity leave (ML) is one of the most important interventions for an extended breastfeeding duration. The aim of this review is to synthesize the available data worldwide on the association of ML and breastfeeding duration. We also intend to provide an overview of whether this association is differential by socioeconomic status. MATERIALS AND METHODS: Relevant primary studies relating ML and breastfeeding were included by searching several databases, including PubMed, SCielo, Health Systems Evidence, Health Evidence, Cochrane Reviews, and Epistemonikos. Articles were included up to May 2018. RESULTS: A total of 239 relevant articles were identified, of them 21 were included in the review based on exposure, outcome, and study design. These studies reported that an extended ML might be related to breastfeeding duration. In addition, studies reporting data on work type, race, and education showed that black women, women in less privileged position, and women with less education have less breastfeeding duration. CONCLUSIONS: This review showed a positive relationship between ML length and breastfeeding duration. These results have a homogeneous trend; however, this was different when studies reported results on ML and breastfeeding stratified by socioeconomic status. Public health policies should ensure that all women, especially the most vulnerable, have equal access to the benefits that ML provides.
