14th International Breastfeeding and Lactation Symposium4-5 April 2019 London, EnglandExclusive Breastfeeding After 40 Years of Age – Where Are We Going?Exclusive breastfeeding (EBF) benefits for the newborn and the mother are well documented (WHO, 2013).Maternal age has increased in most developed countries in the last years (OECD, 2016). Recent studiesfound a negative effect of a higher maternal age on successful EBF (Kitano 2015; Colombo 2018). In oursecond level hospital, the total EBF rate at the time of discharge is 71% and there was noticed an increase inthe number of mothers aged 40 years or older, from 4.2% in 2010 to 10.9% in 2017. The purposes of ourstudy are to verify if EBF is lower in older mothers, to identify risk factors and to delineate strategies toimprove the results in this population.ObjectivesRetrospective study using medical records of newborns from mothers ≥ 40-year-old who were born in our hospital during2018. We registered gestational age, newborn gender and birth weight and we analyzed maternal age, type of delivery,nulliparity, in vitro fertilization (IVF) and Neonatal Intensive Care Unit (NICU) admission as factors that could influence thetype of feeding at the time of discharge.MethodsResultsWe included 346 newborns, 13.4% of all babies delivered in our maternity in 2018. The median maternal age was 41 (40-53). The median gestational age, the average birth weight and the newborn gender are show in the tables. The EBF ratewas 43.1%, ranging from 48.7% in 40-year-old mothers to 37.7% in ≥44-year-old mothers. Caesarean sections (C-section) corresponded to 70.2% of deliveries, with an EBF rate of 35.3% (vs an EBF rate of 61,8% in vaginal deliveries).The EBF rate was 37.5% in nulliparous (vs 45.2% in multiparous), 34.1% in pregnancies from IVF (vs 44,4% inspontaneous pregnancies) and 22.9% in newborns admitted to the NICU level 2 (vs 46,3% in those with no need ofadmission).ConclusionsA higher maternal age negatively influences EBF. We identified other risk factors, such as nulliparity, C-section, IVF and the admission to NICU. It is important to address this risk group and more efforts should bemade both in the prenatal and early postnatal periods to improve breastfeeding practice.Miguel Paiva Pereira, Cláudia Fernandes, Ana Rute Ferreira, Mafalda Lucas, Ana Rodrigues,Cristina MatosUnidade Funcional de Neonatologia, Centro da Criança e do Adolescente(Head Department: Ana Serrão Neto), Hospital CUF Descobertas, Lisboa, PortugalMothers’ epidemiological data (N = 342)Median gestational age 38 (32-41) weeksCaesarean sections 240 (70.2%)Nulliparous 94 (27.5%)In vitro fertilizations 42 (12.3%)Newborns’ epidemiological data (N = 346)Gender 175 ♀ (50.6%)171 ♂ (49.4%)Average birth weight 3123g (±463g)Total EBF rate 149 (43.1%)NICU admissions 48 (13.9%)48,743,436,141,418,20510152025303540455040 41 42 43-45 ≥46EBF rate (%)Maternal age (year old)22,932,5034,137,5043,700 5 10 15 20 25 30 35 40 45 50NICUC-sectionsIVFNulliparousTotalEBF rate (%)
