Table 7 Multivariate logistic regression analysis for factors* related to PPSV23 vaccination intention and behavior (PPSV23 vaccination was defined by questionnaire responses only)

From: Correlation between family physician’s direct advice and pneumococcal vaccination intention and behavior among the elderly in Japan: a cross-sectional study

  OR 95%CI p-value
Personal medical history of pneumonia 0.27 0.04–1.81 0.179
Subjective sense of economic conditions 3.63 0.38–34.95 0.265
Living alone or with others 1.60 0.28–9.02 0.595
Perceived susceptibility to colds 0.73 0.24–2.23 0.583
Perceived severity of pneumonia 1.24 0.35–4.42 0.744
Perceived effectiveness of PPSV23 2.90 1.03–8.15 0.044
Physician’s recommendations 7.37 2.83–19.22 <0.001
Awareness of PPSV23 8.74 2.23–34.31 <0.001
Awareness of public subsidies 1.97 0.68–5.71 0.214
  1. *: The independent variables which were associated with PPSV23 at p < 0.20 in univariate logistic regression analysis were incorporated to multivariate logistic regression analysis
  2. The PPSV23 vaccinated and unvaccinated groups were defined by the questionnaire responses only, irrespective of the vaccination records in electronic medical record. There was a significant relationship between PPSV23 vaccination and perceived effectiveness of PPSV23 (p < 0.05), physician’s direct advice (p < 0.001) and awareness of PPSV23 (p < 0.05)
