Aim: To explore the socio-demographic factors and other maternal characteristics that influence breastfeeding initiation rates. In particular, this paper aims to (i) estimate the rate of breastfeeding by maternal socio-demographic factors and other maternal characteristics at first well-baby visit; and (ii) investigate the relationship between breastfeeding rates and these maternal factors.
Methods: Cross-sectional data were obtained for 9618 babies in south-western Sydney in New South Wales from the Ingleburn Baby Information Systems database from January 2000 to June 2004 and included information on breastfeeding status, socio-demographic factors and other maternal characteristics.
Results: At first visit, 59.8% of mothers were breastfeeding. The factors that increased the risk for NOT breastfeeding on multivariate analysis were being Australian-born (OR=1.67, 95% CI 1.45-1.89, P<0.001), unmarried (OR=1.79, 95% CI 1.52-2.11, P<0.001), living in disadvantaged accommodation (OR=1.90, 95% CI 1.60-2.26, P<0.001), having lower levels of education (OR=1.88, 95% CI 1.38-2.54, P<0.001) and current smoking (OR=1.72, 95% CI 1.51-1.96, P<0.001).
Conclusion: The results from this large population-based study suggest that breastfeeding rates are significantly influenced by socio-demographic factors and maternal characteristics. Consequently, subgroups of the population 'at risk' for not breastfeeding can be identified and targeted for further strategies to promote breastfeeding.
