To characterize human papillomavirus (HPV) prevalence and distribution among female university students in Maputo, Mozambique, and evaluate the determinants of HPV infection.
A cross-sectional study among 504 female university students between February and April 2017. Cervicovaginal self-collected samples were analyzed for HPV genotypes by polymerase chain reaction-restriction fragment length polymorphism and Anyplex II HPV28 Detection kit (Seegene ).
The prevalence of any HPV genotype was 28.6% (144/504). Single and multiple HPV infections were detected in 76 (15.1%) and 68 (13.5%) participants, respectively. Prevalence of high-risk HPV was significantly higher than that of low-risk HPV (P<0.001). HPV16 was the most frequent genotype, followed by HPV58, HPV66, HPV52, HPV18, HPV56, HPV61, and HPV70. The prevalence of genotypes covered by the bivalent, quadrivalent, and nonavalent vaccine was 14.3%, 15.9%, and 23.4%, respectively. Number of sexual partners over lifetime and in the past 12 months was associated with HPV infection (P<0.001 and P=0.039, respectively).
Knowledge of HPV genotype-specific prevalence among young women is important to set up strategies for HPV vaccination. The findings suggest that introduction of the nonavalent HPV vaccine might be the way forward in the present low-resource setting. In addition, self-sampling was useful for HPV detection and genotyping.
描述莫桑比克马普托女性大学生人群中人类乳头瘤病毒(HPV)的流行情况和分布,并评估 HPV 感染的决定因素。
这是一项 2017 年 2 月至 4 月期间对 504 名女性大学生进行的横断面研究。采用聚合酶链反应-限制性片段长度多态性和 Anyplex II HPV28 检测试剂盒(Seegene)对宫颈阴道自我采集样本进行 HPV 基因型分析。
任何 HPV 基因型的流行率为 28.6%(144/504)。76 名(15.1%)和 68 名(13.5%)参与者分别检测到单一和多重 HPV 感染。高危型 HPV 的流行率显著高于低危型 HPV(P<0.001)。HPV16 是最常见的基因型,其次是 HPV58、HPV66、HPV52、HPV18、HPV56、HPV61 和 HPV70。二价、四价和九价疫苗涵盖的基因型的流行率分别为 14.3%、15.9%和 23.4%。一生中和过去 12 个月的性伴侣数量与 HPV 感染相关(P<0.001 和 P=0.039)。
了解年轻女性 HPV 基因型特异性流行情况对于制定 HPV 疫苗接种策略很重要。研究结果表明,在目前资源匮乏的情况下,引入九价 HPV 疫苗可能是未来的发展方向。此外,自我采样对于 HPV 检测和基因分型很有用。
