This systematic review and meta-analysis estimated the prevalence, genotype distribution, and risk factors for human papillomavirus infection among Nepalese women. A total of 8 cross-sectional studies with 6,082 participants were included in this review. For this review, the eligibility criteria included studies reporting HPV prevalence or genotype-specific rates among Nepalese women; thus, database sources were searched up to December 2024. The quality of the studies was assessed, and pooled estimates were computed via random effects models. The pooled prevalence of HPV infection among Nepalese women was 8.31%, with a genotype-specific prevalence of 2.62% for HPV-16 and 1.25% for HPV-18. HPV infection was significantly associated with those whose husbands had multiple sexual exposures. Other factors, including smoking status, educational status, and the use of contraceptives, were not significantly associated. Most analyses showed moderate to high heterogeneity. This review highlights the moderate burden of HPV infection in Nepal; hence, targeted public health intervention through vaccination and screening programs is recommended. Limitations include heterogeneity of studies and an inability to draw causal interference because all the data were cross-sectional. The findings highlight the need for region-specific strategies to combat HPV-related diseases in Nepal and underscore the importance of future research to address existing knowledge gaps.

本系统评价和荟萃分析估计了尼泊尔女性人乳头瘤病毒感染的患病率、基因型分布及危险因素。本评价共纳入8项横断面研究,涉及6082名参与者。对于本评价,纳入标准包括报告尼泊尔女性中HPV患病率或基因型特异性率的研究;因此,检索数据库来源至2024年12月。评估了研究质量,并通过随机效应模型计算合并估计值。尼泊尔女性中HPV感染的合并患病率为8.31%,HPV-16的基因型特异性患病率为2.62%,HPV-18为1.25%。HPV感染与丈夫有多个性接触的女性显著相关。其他因素,包括吸烟状况、教育程度和避孕药具的使用,均无显著相关性。大多数分析显示中度至高度异质性。本评价强调了尼泊尔HPV感染的中度负担;因此,建议通过疫苗接种和筛查计划进行有针对性的公共卫生干预。局限性包括研究的异质性以及由于所有数据均为横断面数据而无法得出因果推断。研究结果凸显了在尼泊尔制定针对特定地区的策略来对抗HPV相关疾病的必要性,并强调了未来研究以填补现有知识空白的重要性。本评价已在PROSPERO注册,注册号为CRD42025632655。
