Spatio-temporal estimates of HIV risk group proportions for AGYW across 13 priority countries in sub-Saharan Africa # multi-agyw Code for the paper Howes *et al.* "Spatio-temporal estimates of HIV risk group proportions for adolescent girls and young women across 13 priority countries in sub-Saharan Africa" (PLOS Global Public Health) > [!NOTE] > This work has now been extended to include males, as well as additional countries. See the UNAIDS Sub-national HIV Estimates in Priority Populations (SHIPP) tool. ## Summary New HIV infections are disproportionately common in adolescent girls and young women (AGYW). Accelerating provision of HIV prevention programming for AGYW is a top priority, but funding is insufficient to reach everyone (HIV Prevention Coalition, 2020). Small-area estimation of risk group population sizes enables countries to prioritise provision of services to those at greatest risk, taking into account both geographic and behavioral factors, as called for in the Global AIDS Strategy 2021-2026. Using AIS, BAIS, DHS and PHIA survey data, we fit multinomial logistic regressions to priority countries using the package `R-INLA`. To enable inference with the `R-INLA` package, each model is reformulated as an equivalent Poisson log linear model using the multinomial-Poisson transformation (Baker, 1994). We use the resulting proportion estimates to disaggregate HIV prevalence and HIV incidence estimates from the Naomi small-area estimation model according to risk group membership. ## Citation If you would like to cite this work, please use: ``` @article{howes2023spatio, doi = {10.1371/journal.pgph.0001731}, author = {Howes, Adam and Risher, Kathryn A. and Nguyen, Van Kính and Stevens, Oliver and Jia, Katherine M. and Wolock, Timothy M. and Esra, Rachel T. and Zembe, Lycias and Wanyeki, Ian and Mahy, Mary and Benedikt, Clemens and Flaxman, Seth R. and Eaton, Jeffrey W.}, journal = {PLOS Global Public Health}, publisher = {Public Library of Science}, title = {{Spatio-temporal estimates of HIV risk group proportions for adolescent girls and young women across 13 prio …
