The changing patterns of infant feeding in Scotland – exclusive or mixed messages? ‘Tomi Ajetunmobi, Bruce Whyte Glasgow Centre for Population Health/ ISD Scotland 10th November, 2011
Introduction/Background Aims and objectives Definitions Results Conclusions Outline
The WHO recommends exclusive breastfeeding for the first 6 months. The benefits of breastfeeding to both mother and infant are well established. In Scotland, although there have been programs and policies set up to improve and monitor breastfeeding, the proportion of exclusively breastfed infants remains one of the lowest in Europe and has remained relatively stable over the past 10 years. Introduction
2 main aims: To carry out analysis using a new using linked dataset in order to investigate breastfeeding trends nationally and locally and to inform future monitoring To investigate the unexpected increase in breastfeeding in selected deprived neighbourhoods within Greater Glasgow and Clyde Background: GCPH Breastfeeding Project
Overview of data schemes Outcome Variables Predictor Variables Infant feeding – initiation (first feed, feed on hospital discharge) Geography (NHS Board, CHP, Neighbourhood area, hospital) NRS(GROS) Maternal characteristics (e.g. maternal age, marital status, ethnicity, socioeconomic characteristics, deprivation, smoking status) SMR02 Pregnancy/Delivery characteristics (e.g. gestation, previous pregnancies, parity, length of stay, mode of delivery, outcome, multiple birth, caesarean section,) CHSP-PS Infant feeding - duration (feed on hospital discharge, feed at community discharge, feed at first visit, 6 to 8 week review, 8-9 month review) SBR/SMR11 Infant characteristics (e.g. APGAR score, birth weight, congenital anomaly, neonatal/infant admission, length of stay) SSBID NRS(GROS) – Births; SMR02 – Maternal hospital records ; CHSP-PS - Child Health Surveillance (pre-school); SBR/SMR11 - Scottish Birth Record/Neonatal and infant health; SSBID - Scottish Still Birth and Infant Death Records

First-time mothers: Mixed feeding and maternal age 2001 and 2009
First-time mothers: mixed feeding as a proportion of any breastfeeding by maternal age
First-time mothers: mixed feeding as a proportion of any breastfeeding by area deprivation
First-time mothers: infant feeding trends by neonatal admission
Mixed feeding as a proportion of any breastfeeding by neonatal admission
Factors that increased the likelihood of mixed feeding compared to exclusive breastfeeding at the first visit
Mixed feeding is associated with: (Further) reduced milk supply Infants separated from mothers due to ill health, work/child care arrangements Flexibility/social contexts Commencing weaning/early weaning practices In other studies…
Exclusive breastfeeding rates have remained relatively static while mixed feeding rates are increasing. Mixed fed infants are similar to exclusively breastfed infants. However compared to exclusively breastfed infants mixed feeding is associated with: Infant ill-health/admission to neonatal ward Maternal health care/delivery characteristics Demographic background of parents (e.g. place of birth, deprivation) Further research will be required to understand the patterns of mixed feeding and its influence on infant health. Conclusion
