Leaflet information by the local government on mental health during the coronavirus disease 2019 pandemic: a cross-sectional study in a rural area in Japan

Abstract

Abstract Background The coronavirus disease 2019 (COVID-19) pandemic and associated infodemic increased depression and anxiety. Proper information can help combat the infodemic and promotes mental health; however, rural residents have more difficulties in getting correct information than urban residents. Objective To examine whether the information on COVID-19 provided by the local government maintained the mental health of rural residents in Japan. Methods A self-administered questionnaire survey of Okura Village (northern district of Japan) residents aged ≥16 years was conducted in October 2021. The main outcomes, depressive symptoms, psychological distress, and anxiety were measured using the Center for Epidemiologic Studies Depression Scale, Kessler Psychological Distress Scale, and Generalized Anxiety Disorder scale 7-item. Exposure was defined as whether the resident read the leaflet on COVID-19 distributed by the local government. The targeted maximum likelihood estimation was used to analyse the effect of leaflet reading on the main outcomes. Results A total of 974 respondents were analysed. Reading the leaflet was significantly lower risk for depressive symptoms relative risk (95% confidence interval): 0.64 (0.43–0.95). Meanwhile, no clear effects of leaflet reading were observed on mental distress and anxiety. Conclusions In rural areas with local governments, analogue information may be effective to prevent depression.
