Prior HIV Testing

 

Percent distribution of women and men who tested HIV positive and who tested HIV negative according to HIV testing status prior to the survey

 

Definition

 

1)      Percent distribution of women and men age 15-49 who tested HIV positive according to HIV testing status prior to the survey.

2)      Percent distribution of women and men age 15-49 who tested HIV negative according to HIV testing status prior to the survey.

 

Coverage:

Population base: Women (or men) age 15-49 tested for HIV in the survey blood test, according to HIV testing status prior to the survey (IR file, MR file, AR file)

Time period: Current status at time of survey

 

Numerators:

1)      Number of women (or men) age 15-49 who tested HIV positive (hiv03 in 1:3) in the survey blood test, according to HIV testing status prior to the survey

2)      Number of women (or men) age 15-49 who tested HIV negative (hiv03 in 0, 7, 9) in the survey blood test, according to HIV testing status prior to the survey

 

HIV testing status prior to the survey is defined as:

·         Ever tested for HIV and received the result of the most recent test (women: v781 = 1 & v828 = 1; men: mv781 = 1 & mv828 = 1):

o   Tested HIV positive during the most recent test prior to the survey (women: v861 = 1; men: mv861 = 1)

o   Tested HIV positive during the most recent test prior to the survey and is currently taking ART (women: v861 = 1 & v863 = 1; men: mv861 = 1 & mv863 = 1)

o   Tested HIV positive during the most recent test prior to the survey and is not currently taking ART (women: v861 = 1 & v863 in 0,8,9; men: mv861 = 1 & mv863 in 0,8,9)

o   Tested HIV negative during the most recent test prior to the survey (women: v861 in 2,5,9; men: mv861 in 2,5,9)

o   HIV test result prior to the survey was indeterminate (women: v861 = 3; men: mv861 = 3)

o   Declined to report HIV test result done prior to the survey (women: v861 = 4; men: mv861 = 4)

·         Ever tested for HIV and did not receive the result of the most recent test (women: v781 = 1 & v828 ≠ 1; men: mv781 = 1 & mv828 ≠ 1)

·         Not previously tested (women: v781 ≠ 1, men: mv781 ≠ 1)

 

Denominators:

a)       Number of women (or men) age 15-49 who tested HIV positive (hiv03 in 1:3) in the survey blood test

b)      Number of women (or men) age 15-49 who tested HIV negative (hiv03 in 0, 7, 9) in the survey blood test

 

Variables: IR file, MR file, AR file.

Calculation

 

The HIV test results data (AR file) should first be merged to the women’s dataset (IR file) or the men’s dataset (MR file) by cluster number (v001/mv001/hivclust), household number (v002/mv002/hivnumb) and line number (v003/mv003/hivline). Cases are weighted by the HIV sample weight (hiv05), not the women’s or men’s sample weights.

 

Numerator divided by the denominator, multiplied by 100.

 

Handling of Missing Values

 

Missing data or “don’t know” responses on whether tested for HIV are treated as never tested. Missing data or “don’t know” responses on whether received results are treated as having not received results. Missing data and “don’t know” responses for the time since the last test are treated as being 12 or more months before the survey. Missing data and “don’t know” responses for result the last test result are treated as HIV negative. Missing data and “don’t know” responses for taking ARTs are treated as no.

 

Notes and Considerations

 

In DHS-7 and DHS-8, for surveys with testing to distinguish between HIV-1 and HIV-2, those found positive for either HIV-1 or HIV-2 (hiv03 in 1,2,3) are considered as HIV positive in these indicators.

 

Prior to DHS-7, for surveys with testing to distinguish between HIV-1 and HIV-2, only those tested and found positive for HIV-1 (including those found positive for HIV-1 only, as well as those found positive for both HIV-1 and HIV-2) (hiv03 in 1,3) are considered as HIV positive in these indicators.
