Stable, heterosexual HIV\u2010serodifferent couples are a priority population of PrEP expansion efforts. We assessed factors associated with PrEP awareness and willingness among HIV\u2010serodifferent couples in SSA to guide PrEP interventions for this population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We conducted a cross\u2010sectional analysis using pooled data from nationally representative, two\u2010stage cluster sampling, HIV\u2010focused household surveys completed during 2019\u20132022 in seven African countries. We analysed data from 1738 persons without HIV aged \u226515 years in stable, heterosexual HIV\u2010serodifferent couples and included clinical information from their partners with HIV. Higher HIV risk was defined by unawareness of a partner's HIV\u2010positive status or having a partner with an unsuppressed viral load (\u2265200 copies\/ml). Lower HIV risk was defined by awareness of a partner's HIV\u2010positive status and having a partner with a suppressed viral load (&lt;200 copies\/ml). We conducted multivariable logistic regression using survey weights and jackknife variance estimation to assess factors associated with PrEP awareness and willingness.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Overall, 18.1% were aware of PrEP, 69.1% were willing to use PrEP and 5.1% had ever used PrEP. Forty\u2010four percent had higher HIV risk. Higher odds of PrEP awareness were associated with being female (adjusted odds ratio [aOR]: 1.73; 95% confidence interval [CI]: 1.15\u20132.59), secondary education or higher (aOR: 6.42; 95% CI: 2.97\u201313.91) and lower HIV risk (aOR: 1.58; 95% CI: 1.00\u20132.48). Higher odds of PrEP willingness were associated with employment in the past year (aOR: 1.55; 95% CI: 1.01\u20132.37), previous PrEP awareness (aOR: 2.44; 95% CI: 1.36\u20134.36) and lower HIV risk (aOR: 1.70; 95% CI: 1.07\u20132.70).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Persons in stable, heterosexual HIV\u2010serodifferent couples with lower HIV risk were more aware of and willing to use PrEP than those with higher risk. Our findings highlight the importance of encouraging HIV status disclosure, educating about HIV\u2010serodifference and PrEP, and providing PrEP linkage during HIV testing and prevention counselling to increase PrEP awareness, willingness and use among HIV\u2010serodifferent couples in SSA.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jia2.26446","type":"journal-article","created":{"date-parts":[[2025,6,19]],"date-time":"2025-06-19T05:39:26Z","timestamp":1750311566000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Factors associated with awareness of and willingness to use PrEP among stable, heterosexual HIV\u2010serodifferent couples in seven African countries, 2019\u20132022"],"prefix":"10.1002","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1898-6202","authenticated-orcid":false,"given":"J.
