Following is a response from Senior DHS Stata Specialist, Tom Pullum:
These Stata lines will summarize the height variable for girls age 0-2 in states 6 and 13. They are correct, except that you must be sure, when you construct "height", from hw3, that you have omitted the missing value codes such as 9999. For those cases, "height" should be coded ".". I would also strongly recommend that you omit children for whom the WHO HAZ score, hw70, (height for age) has been flagged. Some values of hw3 are implausible and are flagged in the construction of the HAZ score. The flagged cases include the cases with hw3=9999, so if you omit the flagged cases, you will not have to explicitly omit the 9999 cases.
Thus I would change your first line to be the following, and would change all the others in the same way.
sum height if v024 ==13 & b8 >=0 & b8 <= 2 & b4==2 & hw70<600 [iw= hv005/1000000 ]
