Impact of structured programs on breastfeeding initiation rates in preterm neonates in a socioeconomically deprived area in France: A 10-year population-based study

Abstract

Structured programs have a positive impact on breastfeeding (BF) but have rarely been evaluated for preterm neonates, frequently combining prematurity and socioeconomic deprivation as risk factors of a low BF rate. We aimed to assess BF initiation rates in very preterm (<33 weeks’ gestational age), moderately preterm (33–36 weeks), and term neonates from 2002 to 2011 in a French administrative district characterized by socioeconomic deprivation. Structured activities to promote and support BF have been implemented in this area since 2002; they all started in neonatal units. This retrospective population-based study analyzed 302,102 first health certificates. Overall, the BF initiation rate significantly increased, from 52.9% [95% CI: (52.3; 53.4)] in 2002 to 61.0% [95% CI: (60.4; 61.6)] in 2011. In 2002, BF initiation rates did not differ between groups, but in 2011, it was higher for very preterm than for term and moderately preterm neonates [74.7% (69.7; 79.6)] vs. 60.9% (60.3; 61.5) and 59.9% (57.6; 62.2), respectively, both P<0.001. In 2011, however, no difference was observed between moderately preterm children and term-born children (P=0.40). The 2.2% yearly increase observed in very preterm neonates significantly differed from the 0.9% yearly increase in the French general population (P<0.001). ConclusionStructured BF programs initiated in neonatal care units may have a positive impact on BF initiation rates in very preterm neonates, but not in moderately preterm neonates, whose specific needs should be further evaluated.
