Hi all,

I see hw70 and hw71 represent height and weight for age z scores relative to modern WHO population standards. These seem to be available only after the production of these WHO standards. For example, the 1999 Zimbabwe survey does not have these variables. I see in later report years, the 1999 Zim data was re-analyzed with these WHO standards to produce comparable stunting and wasting values.

Are there any plans to retrospectively include hw70 and hw71 in surveys that pre-dated the WHO standards? If not, are there WHO standard distributions available somewhere so that we could translate the raw anthro measurements into z scores with this modern reference?
