Objective To investigate the current status of and factors associated with HPV vaccination among preconception women in Nanjing, Jiangsu Province.
Methods 1 724 women at preconception health care clinics of Nanjing Maternity and Child Health Care Hospital from September 2019 to April 2022 were recruited as subjects. A questionnaire survey was conducted focusing on the current status of HPV vaccination. Univariable logistic regression and stepwise regression were used to analyze the data.
Results 29.4% of the participants received HPV vaccine, and most of them had completed the whole course of vaccination (91.3%) with 9-valent vaccine (59.3%) in mainland China (excluding Hong Kong, Macao Special Administrative Region, and Taiwan Province) (84.4%) for more than 6 months (90.9%). Younger age, higher education level, higher personal annual income, living in Nanjing, lower BMI, younger age at first intercourse, no history of previous pregnancy, and no tobacco exposure were associated with higher HPV vaccination rate (P < 0.05). Alcohol usage, menarche age, irregular menstrual cycle, dysmenorrhea, and the family history of gynecological cancers were not associated with HPV vaccination rate (all P > 0.05).
Conclusion The HPV vaccination rate is relatively low among preconception women in a certain area of Nanjing. It is necessary to improve health education and policy support focusing on women with lower education level, lower annual income, and having bred children in future vaccination promotion.
