  • Mapping age- and sex-specific HIV prevalence in adults in sub-Saharan Africa, 2000–2018 [Elektronski vir]
    Haeuser, Emily ...
    Background: Human immunodefciency virus and acquired immune defciency syndrome (HIV/AIDS) is still among the leading causes of disease burden and mortality in sub-Saharan Africa (SSA), and the world ... is not on track to meet targets set for ending the epidemic by the Joint United Nations Programme on HIV/AIDS (UNAIDS) and the United Nations Sustainable Development Goals (SDGs). Precise HIV burden information is critical for efective geographic and epidemiological targeting of prevention and treatment interventions. Age- and sex-specifc HIV prevalence estimates are widely available at the national level, and region-wide local estimates were recently published for adults overall. We add further dimensionality to previous analyses by estimating HIV prevalence at local scales, stratifed into sexspecifc 5-year age groups for adults ages 15–59 years across SSA. Methods: We analyzed data from 91 seroprevalence surveys and sentinel surveillance among antenatal care clinic (ANC) attendees using model-based geostatistical methods to produce estimates of HIV prevalence across 43 coun‑ tries in SSA, from years 2000 to 2018, at a 5×5-km resolution and presented among second administrative level (typi‑ cally districts or counties) units. Results: We found substantial variation in HIV prevalence across localities, ages, and sexes that have been masked in earlier analyses. Within-country variation in prevalence in 2018 was a median 3.5 times greater across ages and sexes, compared to for all adults combined. We note large within-district prevalence diferences between age groups: for men, 50% of districts displayed at least a 14-fold diference between age groups with the highest and lowest prevalence, and at least a 9-fold diference for women. Prevalence trends also varied over time; between 2000 and 2018, 70% of all districts saw a reduction in prevalence greater than fve percentage points in at least one sex and age group. Meanwhile, over 30% of all districts saw at least a fve percentage point prevalence increase in one or more sex and age group. Conclusions: As the HIV epidemic persists and evolves in SSA, geographic and demographic shifts in prevention and treatment eforts are necessary. These estimates ofer epidemiologically informative detail to better guide more targeted interventions, vital for combating HIV in SSA.
