Following is a response from DHS staff member, Tom Pullum:
When a variable is coded with a dot "." it means the variable was NA or Not Applicable for that case. In this survey there was subsampling for anthropometry. Measurement of children's weights and heights only applied to half of the households, alternating from one household to the next within each cluster. A variable v042, "household selected for hemoglobin" applies to weight (hw2) and height (hw3), not just blood tests for hemoglobin concentration. If v042=0, then hw2, hw3, and all variables constructed from hw2 and hw3, such as hw70, hw71, and hw72, are coded with a dot for NA.
You can proceed to analyze the data without any concern for the subsampling. There is no need to compare the children with v042=1 (selected) vs the children with v042 (not selected) because the selection was random.
