Following is a response from Senior DHS Stata Specialist, Tom Pullum:

When apparent inconsistencies such as this come up, I go back to the questionnaire and check the skip pattern. The women's questionnaire for this survey (as for all surveys) is in an appendix to the main report. Questions 901-909 are basic questions about knowledge and all have the same number of NA (not applicable) cases. Q909 is "Can the virus that causes AIDS be transmitted from a mother to her baby" with three options, "during pregnancy; during delivery; during breastfeeding". The only women to proceed to Q911 will be those who responded Yes to at least one of the three options. That's why there are far more NA cases for v824 than for v823. I expect the same kind of filtering is responsible for the large number of NA cases for v3a08m. Just look at the questionnaire to find the filters.
