[Current status of parental decision-making of childhood 13-valent pneumococcal conjugate vaccine immunization and related factors in China].

Objective: To analyze the relationship between health belief and the stages of parental decision-making on childhood 13-valent pneumococcal conjugate vaccine (PCV13) immunization in China. Methods: Cross-sectional multistage survey sampling method was used to select study subjects. The study subjects were parents who were aged 20-45 years and had one and more children ≤5 years old in three cities in China. A self-administered questionnaire designed based on health belief model was used to collect the information. Multinomial logistic regression analysis was used to assess the relationships between perceived susceptibility, perceived severity of illness, perceived effect of PCV13 and stages of parental decision-making on childhood PCV13 immunization. Results: A total of 1 716 valid questionnaires were returned (89.33%). The average age of the study subjects was (35.33±4.95) years, and 79.60% of them were women. In the study subjects, 48.31% had in action, 21.79% were in contemplation and 29.90% were in pre-contemplation. The multinominal logistic regression analysis indicated that high perceived susceptibility (OR=0.14, 95%CI:0.09-0.22; OR=0.54, 95%CI:0.39-0.76), high perceived severity of illness (OR=0.55, 95%CI:0.42-0.73), and high perceived effect of PCV13 (OR=0.27, 95%CI:0.18-0.40; OR=0.51, 95%CI:0.32-0.81) were significantly lower in those who were in contemplation or pre-compared with those who had in action. For study subjects with low perceived susceptibility, high perceived effect of PCV13 might decrease the probabilities of contemplation (OR=0.53, 95%CI:0.32-0.87) and pre-contemplation (OR=0.27, 95%CI:0.18-0.41). For those with high perceived susceptibility, perceived severity of illness might decrease the probability of contemplation (OR=0.43, 95%CI:0.23-0.82). Conclusions: Childhood PCV13 vaccination willingness and level is low in China. It is important to pay greater attention to the intervention on health belief in child parents, such as perceived effect of PCV13, perceived severity of illness, and perceived susceptibility, in health policy development and health promotion.
