Cervical cancer resulting from prior infection with human papillomavirus (HPV) is a significant public health threat against young Japanese women. A national immunization plan to vaccinate 13~16 year old female students against HPV infection has been started in Japan since 2010, and may reach almost full coverage by the end of 2012. Older age females who may already be sexually active are not targeted by this plan but should follow safer sex practices as well as periodic screening of the cervix cytology to reduce their risk of developing cervical cancer. HPV vaccination alone does not offer full protection either, because only some HPV types are covered by the vaccines and the long-term efficacy of the vaccines has not been determined yet. Therefore, we did a survey at an international university in Japan to study the knowledge and attitude of female college students towards prevention of cervical cancer, to examine the age when they start sexual activity and other related attributes that may influence the risk of cervical cancer. We discuss the results of our survey and what they imply for the possible impact of an HPV immunization plan on the risk of cervical cancer in Japan, and conclude by an emphasis on the need to increase awareness among Japanese female adolescents and to enhance the cervical screening rates among older females who are already sexually active.
先前感染人乳头瘤病毒(HPV)引发的宫颈癌对日本年轻女性构成了重大的公共卫生威胁。自2010年起,日本启动了一项针对13至16岁女学生的HPV感染疫苗接种国家免疫计划,到2012年底可能实现几乎全面覆盖。该计划未将可能已有性行为的年长女性作为目标人群,但她们也应遵循更安全的性行为方式,并定期进行宫颈细胞学筛查,以降低患宫颈癌的风险。仅接种HPV疫苗也不能提供全面保护,因为疫苗仅覆盖部分HPV类型,且疫苗的长期疗效尚未确定。因此,我们在日本一所国际大学开展了一项调查,以研究女大学生对预防宫颈癌的知识和态度,调查她们开始性行为的年龄以及其他可能影响宫颈癌风险的相关因素。我们讨论了调查结果及其对HPV免疫计划可能对日本宫颈癌风险产生的影响,并强调有必要提高日本女性青少年的认识,提高已有性行为的年长女性的宫颈筛查率。
