ObjectivesThis study examines how access to COVID-19 information and adherence to preventive measures varies by sociodemographic characteristics, and whether the associations differ among the migrant origin and the general Finnish population. Additionally, the association of perceived access to information with adherence to preventive measures is examined.DesignCross-sectional, population-based random sample.BackgroundEquity in access to information is crucial for securing individual well-being and successful management of a crisis at population level.SettingPersons who have a residence permit in Finland.ParticipantsMigrant origin population constituted of persons aged 21–66 years born abroad, who took part in the Impact of the Coronavirus on the Wellbeing of the Foreign Born Population (MigCOVID) Survey conducted from October 2020 to February 2021 (n=3611). Participants in the FinHealth 2017 Follow-up Survey conducted within the same time frame, representing the general Finnish population, constituted the reference group (n=3490).Outcome measuresSelf-perceived access to COVID-19 information, adherence to preventive measures.ResultsSelf-perceived access to information and adherence to preventive measures was overall high both among the migrant origin and the general population. Perceived adequate access to information was associated with living in Finland for 12 years or longer (OR 1.94, 95% CI 1.05–3.57) and excellent Finnish/Swedish language skills (OR 2.71, 95% CI 1.62–4.53) among the migrant origin population and with higher education (OR 3.56, 95% CI 1.49–8.55 for tertiary and OR 2.87, 95% CI 1.25–6.59 for secondary) among the general population. The association between examined sociodemographic characteristics with adherence to preventive measures varied by study group.ConclusionsFindings on the association of perceived access to information with language proficiency in official languages highlight the need for rapid multilingual and simple language crisis communications. Findings also suggest that crisis communications and measures designed to influence health behaviours at population level may not be directly transferable if the aim is to influence health behaviours also among ethnically and culturally diverse populations.
