"Summary of results
Initiation of breastfeeding
In England the breastfeeding initiation rate was 73.9% in 2012/13, which is similar to the annual percentage for 2011/12 (74.0%) and slightly higher than 2010/11 (73.7%), 2009/10 (72.8%) and 2008/09 (71.7%) (Table 1).
Amongst SHAs, the initiation rate varied from 59.3% in North East SHA to 86.8% in London SHA (Table 4).
Amongst the 147 PCTs that passed validation, breastfeeding initiation ranged from 40.8% in Knowsley PCT to 94.7% in Haringey Teaching PCT (Table 4).
Prevalence of breastfeeding at 6-8 weeks
The 6-8 week breastfeeding prevalence figures are based on the number of infants recorded by PCTs as totally or partially breastfeeding, as a percentage of all infants due a 6-8 week check.
When making comparisons over time, it is best to limit this to those quarters with high and consistent levels of coverage. There is evidence that the significant improvements in data coverage that were achieved in the early quarters of data collection affected the comparability of the prevalence estimates over time. This is because improvements in coverage have resulted in the inclusion in the statistics of a disproportionately higher number of women who are not breastfeeding.
In England the breastfeeding prevalence at 6-8 weeks in 2012/13 was 47.2% of infants due a 6-8 week check, the same as recorded in 2011/12 (Table 2).
In England the breastfeeding prevalence at 6-8 weeks in 2012/13 Quarter 4 was 46.8% of infants due a 6-8 week check, similar to the figure of 46.9% recorded in 2011/12 Q4 (Table 2).
Amongst the seven SHAs who passed validation, prevalence as a percentage of infants due a 6-8 week check varied from 31.9% in North East SHA to 50.7% in South Central SHA (Table 6).
Amongst the 125 PCTs that passed validation, breastfeeding prevalence as a percentage of infants due a 6-8 week check ranged from 15.7% in Knowsley PCT to 81.6% in City & Hackney PCT (Table 6)."
