摘　　要：目的探讨膳食水溶性维生素对低度宫颈上皮内瘤变(CINⅠ)转归的影响。方法采用以社区为基础的前瞻性队列研究方法,从课题组于2014年建立的已婚女性队列中,选择经病理学确诊的564名CINⅠ患者为研究对象,在收集一般基线资料的同时,应用导流杂交技术检测HPV分型,采用食物频数问卷调查膳食水溶性维生素的摄入情况,确定暴露水平,进而对研究对象进行12个月的随访观察。随访结束时再次取活检组织行病理学检查,判定CINⅠ患者的逆转、持续和进展情况。采用SPSS 22.0软件进行相关资料的分析。结果膳食水溶性维生素低水平可促进CINⅠ患者的持续或进展,且CINⅠ不良转归的风险随维生素摄入水平的降低而升高,尤其是叶酸、维生素B1、维生素B2、维生素B6、烟酸、生物素和维生素C(RR值分别为15.22、1.86、1.92、2.11、2.98、2.14和2.19)低水平对CINⅠ的持续/进展起到重要促进作用。结合HR-HPV感染状况进行分析后显示,HR-HPV阳性时,叶酸、烟酸和生物素低水平可促进CINⅠ持续和进展。结论膳食水溶性维生素低水平是CINⅠ持续和进展的重要促进因素,对于HR-HPV阳性女性,叶酸、烟酸和生物素的作用更为明显。Objective To explore the effect of dietary water-soluble vitamins on the poor prognosis of low-grade cervical intraepithelial neoplasia(CINⅠ).Methods A total of 564 participants with CINⅠwere selected from a community-based married women cohort established in 2014.The general baseline information was collected,and HPV genotyping was detected.A food frequency questionnaire was used to investigate dietary water-soluble vitamins'consumption and determine their exposure levels.The follow-up program was carried out for 12 months,and the regression,persistence,and progression of CINⅠwas determined according to histopathological results at 12-month.Results The low-levels of dietary water-soluble vitamins could promote CINⅠ's persistence and progression,showing the increasing tendency of CINⅠpoor prognosis with the decrease of water-soluble vitamin levels.Especially folate,VB1,VB2,VB6,niacin,biotin,and VC(RR values were 15.22,1.86,1.92,2.11,2.98,2.14,2.19,respectively)played an important role.Considering the status of high-risk human papillomavirus(HR-HPV)infection,our results showed that the low levels of folate,niacin,biotin could promote the poor prognosis of CINⅠ.Conclusions The low-level of dietary water-soluble vitamins could facilitate the poor prognosis of CINⅠ.In addition,folate,niacin,biotin were more effective on HR-HPV positive women.
