This study investigated factors associated with PV completion among a random sample of community-living older adults in China. In addition, Researchers also investigated factors related to receiving a single dose of PV among older adults with at least one high-risk condition.

750 community-living Chinese-speaking individuals aged ≥65 y in Hong Kong completed a random telephone survey from May to July 2019. PV completion was 10% among all participants. Among participants with high-risk conditions for severe IPD, 11.4% received a single dose of PV. After adjustment for significant background variables, several Health Belief Model constructs were significantly associated with both dependent variables: perceived risk of contracting pneumococcal diseases, perceived benefits of PV for protecting themselves or others, perceived barriers to PV uptake, being suggested by significant others to take up PV, and confidence to take up PV.

In addition, being knowledgeable about pneumococcal diseases and vaccination and knowing at least one peer of similar age who had taken up PV were also positively associated with both dependent variables. Targeted, theory-based health promotion efforts are needed to increase PV coverage among the elderly in Hong Kong.
