ABSTRACT

Effectiveness of health professionals' messages via digital tools on COVID-19-related outcomes remains unknown. In this systematic review, we examined this issue by searching randomized controlled trials in six databases until August, 2022 (PROSPERO, CRD 42022350788). Risk of bias was assessed using revised Cochrane risk-of-bias tool. Primary outcomes were COVID-19 infections, preventive behaviors, and factors that support behavioral change. Seven trials with 16 reports (some reported two or more outcomes) were included. One trial showed that physician videos distributed by Facebook ads significantly reduced COVID-19 infections. Five of 6 reports showed that interventions can promote non-pharmaceutical preventive behaviors, vaccination, or information-seeking behaviors and half of the results were significant. Interventions improved the factors that support behavioral change. 14 reports had some concerns of bias risk and 2 had high risk of bias. Our findings suggest that digital messages by health professionals may help reduce COVID-19 infections through promoting behavioral change.

ABSTRACT

Coronavirus disease 2019 (COVID-19) vaccination of adolescent and young adults is important for infection control. Factors influencing vaccination behavior in this age group include the source of information about the vaccine and social norms. However, there are few studies on factors influencing vaccination behavior among Japanese university students. This study aimed to assess beliefs, attitudes, and sources of information about the COVID-19 vaccine among university students in Japan. A cross-sectional online questionnaire survey was conducted among students in Teikyo University, Japan in September, 2021. The survey was designed to collect demographic information, vaccination status, attitudes, beliefs, and anxiety about the vaccine, sources of information, and whether or not the participant watched an educational movie. The factors associated with beliefs and attitudes were analyzed using logistic and linear regression. A total of 4,062 valid questionnaires were retrieved. The positive vaccine behavior group included 3,725 students (91.7%). The most common source of information on the COVID-19 vaccine was TV/radio (75.0%), and the most common Social networking service (SNS) for COVID-19 information was Twitter (31.1%). Approximately 85% students believed in the efficacy of vaccination. Positive attitude was associated with female sex and watching an educational movie by the university. Concern about the vaccine was positively associated with information from acquaintances or Instagram, and negatively associated with information from Twitter, and watching the educational movie. The majority of students had positive beliefs and attitudes toward COVID-19 vaccination, and social media and educational movies produced by the university had a large influence on their attitude toward vaccination behavior. On the contrary, some students were anxious about vaccination. Promotion of educational movies on social media by the universities is an effective way to encourage vaccination among young people.
