RESUMO
HPV prevalence in Nigeria has been challenging to quantify given regional population heterogeneity and differences in diagnostic methodology. We conducted a systematic review and meta-analysis of 17 studies, each of which summarized HPV prevalence in women residing in six geopolitical zones of Nigeria. The estimated pooled prevalence (effect size) of HPV in Nigeria was 32% (CI: 23-41%). HPV prevalence was 29% (CI: 20-39%) among studies that detected HPV by genotype. HPV prevalence among studies that used serologic detection was 38% (CI: 12-65%). When stratified by region, a study in the South East (SE) geopolitical zone reported the highest prevalence of 71% (CI: 61-80%) while a study in the South South (SS) geopolitical zone reported the lowest prevalence of 4.9% (CI: 3-9%). HPV prevalence in Nigeria was high. Heterogeneity between study regions and differing HPV detection methods both contribute to variation in estimates. Using pooled estimates serves to inform future strategies for epidemiologic surveillance and future design of HPV and cervical cancer prevention initiatives. (Afr J Reprod Health 2022; 26[6]:89-96).
