Relationship between health literacy and COVID-19 knowledge: A cross-sectional study.

Background: Health literacy (HL) is a protective factor for some chronic diseases. However, its role in the Coronavirus Disease 2019 (COVID-19) pandemic has not been clarified. This study aims to explore the association between HL and COVID-19 knowledge among residents in Ningbo. Methods: A total of 6,336 residents aged 15-69 years in Ningbo were selected by multi-stage stratified random sampling method. The "Health Literacy Questionnaire of Chinese Citizens (2020)" was used to evaluate the relationship between COVID-19 knowledge and HL. Chi-square test, Mann-Whitney U test and logistic regression were used to analyze the data. Results: The HL and COVID-19 knowledge levels of Ningbo residents were 24.8% and 15.7%, respectively. After adjusting for confounding factors, people with adequate HL were the more likely to have adequate COVID-19 knowledge compared with those with limited HL (OR = 3.473, 95% CI = 2.974-4.057, P <0.001). Compared with the limited HL group, the adequate HL group had a higher rate of COVID-19 knowledge, a more positive attitude, and a more active behavior. Conclusion: COVID-19 knowledge is significantly associated with HL. Improving HL may influence people's knowledge about COVID-19, thereby changing people's behaviors, and finally combating the pandemic.

Digital Technology and Innovative Technology to Promote the Professional Development of Digital Media Based on Green Energy under COVID-19

Taking as an example the practical teaching of the design of children's solar-energy-based ultraviolet disinfection products, we analyzed the practical activities in four stages of teaching-case background, research methods, product design, and practical results-in the practical teaching mode based on solar green energy. This paper presents and proposes a design solution for a solar-powered green energy-based multifunctional inductive UV disinfection product for children to provide additional services for school interventions and improve public health in primary and secondary schools. This new innovative design for a children's disinfection product is based on solar green energy and enhances the graded disinfection strategy in schools, reducing the number of viruses and the potential risk of virus transmission in the educational environment. The proposed program aims to be project-oriented, combining green energy concepts with innovative educational concepts, classroom content with social prevention products, digital technology with innovative thinking, promoting the development of innovative and digital abilities of teachers and students, and promoting the development of practical teaching in digital media. The practical results show that the model has positive teaching effects, practical value for students, schools and society, cultivation of digital innovation ability of teachers and students, and reference significance for practical teaching.

Impact of Covid-19 on the Behavior of Community Residents With Suspected Transient Ischemic Attack.

Background and Purpose: To investigate the impact of the novel coronavirus disease 2019 (Covid-19) on the behavior of those seeking medical attention for community residents suspected of having had a transient ischemic attack (TIA) during the pandemic. Methods: This was a community-based cross-sectional study with residents living in two communities located in the suburb of Shanghai. A face-to-face interview was prospectively conducted from 20 May 2020 to 30 June 2020 between community physicians and the community residents. Suspected TIA that occurred during the pandemic was identified by symptoms recalled from the community residents. The behavior of seeking medical attention after the suspected TIA was investigated. Results: A total of 873 community residents (517 from the Wujing community and 356 from the Maqiao community) took part in face-to-face interviews. Among them, 143 (16.38%) suspected TIA cases were identified. Less than 20% of the community residents suspected of having a TIA went to the hospital during the Covid-19 pandemic. The most common reason for not seeking medical care during the pandemic was still that symptoms disappeared quickly (94.9%); however, the pandemic did have an impact on behavior. Fear of in-hospital infection (55.1%) and of complicated procedures involved in seeking medical attention during the pandemic (55.9%) made community residents hesitate to seek medical attention after the suspected TIA. Residents with a dual attack within 1 week or with aphasia or dysarthria were more likely to seek medical attention during the pandemic. Conclusion: Our study indicated that the Covid-19 pandemic negatively affected the behavior of those seeking medical attention among community residents with suspected TIA and this might explain part of the reduction in patients presenting with stroke or TIA observed from other reports.
