Prevalence of breastfeeding in industrialized countries

Given the benefits of breastfeeding (BF), healthcare institutions recommend that a child should be breastfed for the first 6 months of its life. This study provides a review of BF as a function of socioeconomic criteria in various industrialized countries.

A review was carried out between 1st January 1998 and 1st March 2009, using Medline and the Public Health Database. The papers were selected independently by two persons, using a methodological grid designed to evaluate the quality of the studies. From 1126 initially selected papers, 26 from 16 different countries were retained for further analysis.

The prevalence of exclusive BF initiation was the highest in Norway, Denmark, and Japan with, respectively, 99, 98.7, and 98.3%. This prevalence was the lowest in the United Kingdom, the United States, and France with, respectively, 70, 69.5, and 62.6%. Women who breastfeed less were most commonly found to be young, single, from a low socioeconomic group, or with a low level of education. Women from immigrant population groups breastfed more than the native-born population during their pregnancy.

Knowledge of the sociodemographic distribution of women who breastfeed is essential for the definition of preventive policies, which are needed to reduce health-related social inequalities. An in-depth analysis of existing primary healthcare programs would allow new strategies to be defined.
