Prevalence and determinants of influenza vaccination in the Hong Kong Chinese adult population

Abstract

Background: The study examined the prevalence and associated factors of influenza vaccination (IV) among the general adult population in Hong Kong.

Methods: A population-based, random telephone survey interviewed 1,102 Hong Kong Chinese adults aged 18-64 years old in 2006.

Results: Of all study participants, 95.5% had heard of IV, and only 28.1% had ever received IV. Associated factors included knowledge that IV is required annually, variables related to the Health Belief Model (HBM) (eg, perceived adverse effects, perceived efficacy), and advices given by health care professionals.

Conclusions: The prevalence of IV was moderately low and factors related to the HBM were found predictive of IV.
