Does anyone know about this study?

[TinkerBellesMumandFiFi2]

I was talking to the wonderful NN-MW who visits me yesterday about the problems I'd had with my HV last time (she's started to be difficult again this time) who can't have enough experience of breastfed prems because she was (and is) constantly panicking about weight gain. The MW told me that there was a study done in 2007 over the world (developing and developed countries too) that showed that at 1 year breastfed children are 1lb lighter than FF children. She said the study is continuing as they will be looking at the weight at five years. Apparently it's to do with obesity.

I'm interested in reading about it for myself if anyone knows about it and has a link.

UK study here

I can't find an international one, but will look more later

The WHO longitudinal study which led to the formulation of the new weight charts showed that after about 6 mths, bf babies start to look lighter than ff babies. This was international.

WHO Child Growth standards. New UK charts using the data from this study are being rolled out in the UK in the red books from this Spring.

are the charts massively different to the ones being used today Grendle?

In terms of the data underpinning the new charts, there's some info here on the differences, though it's a bit techie. In general, more babies will be flagged as underweight by the new ones. However, as tiktok says, in the early days the new charts actually predict faster growth, as is the case when breastfeeding goes well. Then they reflect slower growth from around 2 months onwards (see slide 47 in the link above). The largest difference occurs at around 14 months, when the new charts show babies as being significantly lighter than the current red book charts (UK90). The charts then gradually converge again to around 5 years.

As for what the new charts actually look like compared with the old ones, then my understanding is that they have been re-worked and will look a little different. In particular, the text accompanying them has been improved and tested with parents and health professionals.

Just re-read my post. It should say less babies will be flagged as underweight, not more.
