HIV Prevalence among Couples

 

Percent distribution of couples living in the same household by HIV status

 

Definition

 

Percent distribution of couples living in the same household, both of whom were tested for HIV in the survey, by HIV status of each partner.

 

Coverage:

Population base: Couples living in the same household, both of whom were tested for HIV (CR file, AR file).

Time period: Current status at time of survey.

 

Numerators:

Number of couples living in the same household where:

1)      Both were HIV positive (w_hiv03 in 1:3 & m_hiv03 in 1:3)

2)      The man was HIV positive and the woman was HIV negative (w_hiv03 ≠ 1:3 & m_hiv03 in 1:3)

3)      The woman was HIV positive and the man was HIV negative (w_hiv03 in 1:3 & m_hiv03 ≠ 1:3)

4)      Both were HIV negative (w_hiv03 ≠ 1:3 & m_hiv03 ≠ 1:3)

 

See Calculation below for creation of w_hiv03 and m_hiv03.

 

Denominator: Number of couples living in the same household, both of whom were tested for HIV (w_hiv03 in 0:3 & m_hiv03 in 0:3)

 

Variables: CR file, AR file.

v001

Cluster number (women)

v002

Household number (women)

v003

Line number (women)

mv001

Cluster number (men)

mv002

Household number (men)

mv003

Line number (men)

hivclust

Cluster

hivnumb

Household

hivline

Line

hiv03

Blood test result

hiv05

HIV Sample weight

 

Calculation

 

The HIV test results data (AR file) should first be merged to the data for the female member of the couple in the CR file by cluster number (v001/hivclust), household number (v002/hivnumb) and line number (v003/hivline), merging in just the HIV test results variable (hiv03). The merged variables hiv03 should be renamed as w_hiv03. Then merge the AR file to the data for the male member of the couple in the CR file by cluster number (mv001/hivclust), household number (mv002/hivnumb) and line number (mv003/hivline), merging in the HIV test results variable (hiv03) and the HIV sample weight (hiv05). The merged variables hiv03 should be renamed as m_hiv03. See Matching and Merging Datasets in Chapter 1.

 

Cases are weighted by the HIV sample weight from the man’s HIV test results data (hiv05), not the women’s or men’s sample weights.

 

Numerator divided by the denominator, multiplied by 100.

 

Notes and Considerations

 

The couples recode (CR file) contains a dataset of merged variables combining data from the women’s dataset (IR file) and the men’s dataset (MR file). The data are merged on the following variables: Cluster number (v001/mv001), household number (v002/mv002) and husband’s/man’s line number (v034/mv003). Note that the husband’s line number (v034) from the women’s data is matched to the man’s line number (mv003) in the men’s data.

 

Changes over Time

 

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.
