Following is a response from Senior DHS staff members, Tom Pullum:
These variables usually have different survey-specific names in different surveys, but I see that in the Ghana 2022 survey the names begin with v, so perhaps the names are becoming standard.
I opened the IR file in Stata and entered "lookfor cancer". I got the following two lines:
storage display value
variable name type format label variable label
-----------------------------------------------------------------------------------------------------
v484a byte %8.0g V484A breasts examined for cancer by health care provider
v484b byte %8.0g V484B ever tested for cervical cancer by health care provider
Here are the labels:
. label list V484A
V484A:
0 no
1 yes
8 don't know
. label list V484B
V484B:
0 no
1 yes
8 don't know
You can get the unweighted distributions with "tab1 v484*". You get the weighted distributions with "tab1 v484* [iweight=v005/1000000]]".
The women are not asked about symptoms or a diagnosis.
We would usually treat "don't know" as "no".
There are no formulas. We cannot give more syntax for your analysis--these are simple yes/no variables.
