Anxiety among dental professionals and its association with their dependency on social media for health information: insights from the COVID-19 pandemic

Background: Social media can play a detrimental role during a global health emergency. In this study, we aimed at assessing the impact social media has on the anxiety level of dental healthcare workers (DHCWs) whilst living through the COVID-19 pandemic. Methods: An online questionnaire was disseminated to a cross-sectional sample of DHCWs from 19 countries using social media platforms. The questionnaire enquired about DHCWs' frequency of using social media and their dependency on health-related information posted on those platforms. Anxiety was measured using General Anxiety Disorder scale (GAD-7). Results: Four-hundred and three (403) DHCWs completed the online questionnaire. Sixty-eight percent (68%) frequently use social media for information on COVID-19. The frequency of social media use was higher among younger DHCWs, with shorter clinical experience, and holders of undergraduate qualifications (p = 0.009, p = 0.002, and p = 0.023, respectively). Almost one third of DHCWs had moderate to severe anxiety (31.7%), which was significantly associated with the frequency of social media use (p = 0.016). This association was adjusted for age, years of experience and qualification level (OR 1.75; 95% CI 1.05-2.93; p = 0.032). Conclusion: COVID-19 social media infodemic has been adversely impacting the psychological wellbeing of DHCWs. More effective measures are needed to control the quality and spreadability of health information on social media platforms.
