Quick thoughts, but I suspect a DHS person will chime in with some details:
1 - There is a sampling frame issue regarding "kids born to survey mothers" or "kids in the household", which are not always the same. Could that explain some of it?
2 - the WHO sample would likely drop a few different kids than the old standards, if in one or the other the kid is less than the "acceptable range" (-5 or -6 HAZ).
3 - You can just re-calculate your own z-scores using the WHO measures using the Stata package zscore06 and using gender, raw height, and age-in-fractions-of-months (if there is a given birth day and not just birth month). Then you should be able to tell why some are there and some aren't, or at least test (2) above.
Hope one of those helps a little bit, or at least gives a real DHS person some concrete ideas to shoot down.
