Abstract Objective To analyze the relationship between bacterial vaginosis (BV) and vaginal microecological changes with high risk human papillomavirus (HR-HPV) infection. Methods The clinical data of 1768 female vaginal secretions screened by HR-HPV from July to December 2016 were analyzed retrospectively. 1768 women were divided into HR-HPV positive group and negative group. Vaginal microecological indicators (pH, sialidase, hydrogen peroxide and leukocyte esterase) and bacterial vaginosis were compared between the two groups. Results Among 1768 subjects, 527(29.80%) were HR-HPV positive and 1241 (70.20%) were HR-HPV negative. BV was found in 114 cases (6.44%). The proportion of BV was 11.57% in HR-HPV positive group and 4.27% in HR-HPV negative group. The proportion of BV was significantly different between the two groups (P < 0.05). All the four indexes of microecology were positive (pH>4.5, sialidase positive, hydrogen peroxide positive, leukocyte esterase positive) in 98 cases (5.54%). In HR-HPV positive group, the composition ratio of all the four indexes of microecology was 8.54%, in HR-HPV negative group, the composition ratio of all the four indexes of microecology was 4.27%, and in vaginal microecology, the composition ratio of all the four indexes of microecology was statistically significant (P < 0.05). Conclusion Bacterial vaginosis and vaginal microecology are closely related to HR-HPV infection. Reducing the occurrence of bacterial vaginosis, maintaining vaginal microecological balance, can reduce the infection rate of HR-HPV.
