Approximately, 70% of cervical cancer cases worldwide are attributable to HPV-16 and HPV-18, with HPV-associated cancers being the second most common infection-related cancers globally. However, there´s paucity of data about this infective agent in Central Nigeria. In a cross-sectional study, we evaluated the seroprevalence of HPV-16 immunoglobulin G (IgG) and risk determinants among women in Central Nigeria as a first step towards evaluating anti-HPV IgM antibody for active cases and determining incidence. Blood samples were collected between August 2016 and January 2018, from 400 consenting women of childbearing age (15-49 years) who completed structured questionnaires. Samples were analyzed using HPV-16 specific IgG ELISA kits (Cusabio Co. Ltd, Germany). Statistical analysis was performed to determine predictors. Overall, we found that 128 (32.0%) had IgG antibody against HPV-16. Seroprevalence by age was 50.0% (15-19 years), 55.0% (20-24 years), 12.9% (25-29 years), 50.0% (30-34 years), 32.1% (35-39 years), 18.2% (40-44 years) and 19.4% (45-49 years) respectively. Factors associated with infection were age (P=0.0002; 95% CI 5.06-31.51), occupation (P<0.0001; 95% CI 1.4-12.6), number of sex partners (P=0.0037; 95% CI 1.27-49.93), history of genital warts (P=0.0203; 95% CI 1.34-9.55) and education level (P<0.0001; 95% CI 3.89-60.11). In addition, forty six (11.5%) reported having the history of genital warts with 268 (67.0%) and 132 (33.0%) subjects being married and single respectively. Individuals who were either artisans or civil servants were 260 (65.0%), whereas 140 (35.0%) were students. Majority, 324 (81.0%), had either primary, secondary or tertiary education with 76 (19.0%) of the subjects having no formal education. In respect of sexual behaviour, 196 (49.0%) reported having at least two sexual partners, out of which 64 (16.0%) had three or more. These findings provide high serological evidence of exposure to HPV-16 in Central Nigeria with implications for national and regional intervention initiatives.
全球约 70%的宫颈癌病例可归因于 HPV-16 和 HPV-18,HPV 相关癌症是全球第二大常见的感染相关癌症。然而,关于这种感染因子在尼日利亚中部的数据很少。在一项横断面研究中,我们评估了尼日利亚中部育龄妇女(15-49 岁)中 HPV-16 免疫球蛋白 G(IgG)的血清流行率,这是评估抗 HPV IgM 抗体用于活动性病例并确定发病率的第一步。2016 年 8 月至 2018 年 1 月期间,从 400 名同意的育龄妇女(15-49 岁)中采集了血液样本,这些妇女完成了结构化问卷。使用 HPV-16 特异性 IgG ELISA 试剂盒(Cusabio Co. Ltd,德国)对样本进行了分析。为了确定预测因素,进行了统计分析。总体而言,我们发现 128 名(32.0%)妇女对 HPV-16 有 IgG 抗体。按年龄划分的血清流行率分别为 50.0%(15-19 岁)、55.0%(20-24 岁)、12.9%(25-29 岁)、50.0%(30-34 岁)、32.1%(35-39 岁)、18.2%(40-44 岁)和 19.4%(45-49 岁)。与感染相关的因素是年龄(P=0.0002;95%CI 5.06-31.51)、职业(P<0.0001;95%CI 1.4-12.6)、性伴侣数量(P=0.0037;95%CI 1.27-49.93)、生殖器疣病史(P=0.0203;95%CI 1.34-9.55)和教育程度(P<0.0001;95%CI 3.89-60.11)。此外,46 名(11.5%)报告有生殖器疣病史,其中 268 名(67.0%)和 132 名(33.0%)已婚和单身。工匠或公务员占 260 人(65.0%),而学生占 140 人(35.0%)。大多数人(81.0%)接受过小学、中学或高等教育,其中 76 人(19.0%)没有接受过正规教育。关于性行为,196 人(49.0%)报告至少有两个性伴侣,其中 64 人(16.0%)有三个或更多性伴侣。这些发现提供了 HPV-16 在尼日利亚中部高度血清学暴露的证据,对国家和区域干预倡议具有重要意义。
