PurposeThe purpose of the article is to introduce the outcomes of a study analyzing the relationships between willingness to use technology for health purposes, health information behavior (HIB), health behavior (HB) choices, readiness for COVID-19 vaccination, socioeconomic indicators and self-reported health among older adults aged = 50 years living in Estonia.Design/methodology/approachA cross-sectional survey was conducted among 501 people aged = 50 in Estonia in 2020, a month after the end of lockdown.FindingsThe results of the study indicate that the more recurrent the need for HI was (rho = 0.11, p < 0.05) and the more regularly one searched for it (rho = 0.14, p < 0.01), the more willing a person was to get vaccinated. Also, interest in digital applications corresponded to vaccination readiness (rho = 0.25, p < 0.001). However, this relationship did not emerge in the case of other HBs such as healthy eating and exercise. Differences in HIB should be taken into account when developing effective means of health communication designed especially for crisis situations.Originality/valueEstonia is known as one of the digital front runners in the world. However, social welfare and the well-being of disadvantaged groups among the population (e.g. older people) have not yet caught up with the more developed Western countries. Thus, learning more about the health-related information behavior of older adults, e.g. the kind of health information they are seeking and using in Estonia, allows policymakers, health information providers and libraries in Estonia to plan and carry out more effective interventions and help them to improve the existing systems so as to furnish older adults with relevant information.
