以理論為架構探討影響孕婦季節性流感疫苗接種意圖之相關因素：以臺北市立聯合醫院為例

Factors associated with the behavioral intention towards receiving a seasonal influenza vaccine during pregnancy - an empirical study at Taipei City Hospital

目標：本研究旨在探討影響孕婦接種季節性流感疫苗行為意圖之相關因素。方法：本研究為橫斷性研究，並運用健康信念模式及參酌相關文獻設計測量工具。研究對象為2016年8至9月間至臺北市立聯合醫院婦產科候診之孕婦共315位。本研究以SAS 9.4版進行資料處理，以STATA 13版進行多元線性迴歸分析。結果：孕婦自覺利益越大、自覺障礙越小、行動線索越多、自我效能越好、主觀規範程度越高、預期擔心越多，以及社會規範越低，其流感疫苗接種意願越高。結論：建議針對影響孕婦接種流感疫苗之重要因子如自覺利益、自覺障礙，以及自我效能等設計衛生教育策略，如強化接種疫苗對孕婦及胎兒的利益或移除其對疫苗安全性疑慮等障礙。

Objectives: This study aimed to investigate the factors associated with the behavioral intention towards influenza vaccination. Methods: This was a cross-sectional study. The instruments were developed based on the Health Belief Model and related literature. The participants were the 315 pregnant women who had prenatal visits between August and September 2016 at the Fuyou Branch of Taipei City Hospital. We used SAS 9.4 for data processing, and STATA 13 for multiple linear regression analysis. Results: The participants with more perceived benefits, less perceived barriers, more cues to action, higher self-efficacy, higher subjective norms, more anticipated worry, and lower social norms were more willing to receive influenza vaccine. Conclusions: Our findings suggest that health education strategies should be designed with a focus on the important determinants influencing intention towards vaccination, such as selfperceived benefits, self-perceived barriers, and self-efficacy. Such strategies include enhancing perceived benefits for the pregnant women and their babies, and clarifying the safety issues to remove the barriers.
