It is a well-known practice in all DHS surveys which includes a HIV module and a male survey, the module will be restricted to the sub-sample of households selected for male survey, so was the Cameroon DHS 2011. Though it might not be mentioned explicitly in the text of the chapter, the questionnaire indicated clearly that the HIV knowledge and HIV testing are restricted to the households selected for male survey (See page 518 of the report). So the 7457 women in table 14.11.1 were from the households selected for male survey.
