5.6. HIV-concordance and -discordance among married and cohabitingcouplesIn this section we examine married or cohabiting couples living in the same household who bothconsented to HIV testing. Households with two partners who both were tested for HIV in KAISaccounted for 28% of all households surveyed.Married and Cohabiting Couples in KAIS: The Couples DatasetDATA IN CONTEXTThe “couples” dataset in the 2007 KAIS was constructed by matching respondents with theirprimary sexual partners who resided in the same household. Because only 0.1% of maleheads of household reported a second wife, only primary couples were included in thecouples’ dataset. Additionally, since HIV status of couples was the main focus of theseanalyses, only households for which there were complete HIV test results available for bothpartners were included in the couples’ dataset. Of the 9,691 eligible households, 2,752 (28%of all households, or 58% of households with at least one sexual partner) met these criteriaand were included in the final analyses.Total Households(n=9,691)100%Head of Household andat least One Partner(n=4,754)49%Both Head of Householdand Partner CompletedInterview (n=3,256)34%Both Head of Householdand Partner CompletedTesting (n=2,752)28%0 10 20 30 40 50 60 70 80 90 100Percent (%) of All Households Sampled in the 2007 KAISHIV‐discordant couples in married or cohabiting partnerships are a target group for HIV preventionbecause they may have more frequent sexual contact and report lower condom use compared topartners in other types of relationships.
