Adequacy of public health communications and health propaganda on the prevention of coronavirus disease in Jiangsu province: a community-based cross-sectional study
Abstract Background: To measure the public’s awareness of COVID-19 and evaluate the adequacy of public health communications and health propaganda on the prevention of coronavirus disease in Jiangsu province.Methods: We made an electronic questionnaire and launched the survey during February 12 to March 12, 2020. Respondents were randomly selected and recruited from thirteen cities in Jiangsu province. An opportunistic sampling approach was also used to recruit new participants or members in the same household through referrals from existing participants. Data was collected through the “Questionnaire Star” system. SPSS24.0 version was used for data statistical analysis.Result:The effective response rate of completing questionnaire was 97.14% (2650/2728). Compared with traditional media such as TV (51.43%) and newspaper (14.91%), participants were more willing to choose new media such as websites (71.17%) and social platforms such as We-Chat (73.96%) to obtained health information. Chi-square test showed that women (54.14% vs. 48.49%), the 20-50 age group (24.22% vs. 22.94%, 32.69% vs. 31.40%, 28.92 vs. 27.77%) and urban residents (61.42% vs. 59.85%) had higher COVID-19 preventive knowledge level, urban residents had better attitude (60.29% vs. 59.85%), women (53.53% vs. 51.51%), the 30-50 age group (33.14% vs. 31.40%, 29.00% vs. 27.77%)), urban residents (61.50% vs. 59.85%) had good behavior. Multivariate logistic analysis showed that gender (females vs. males, OR=2.226, OR 95%CI: 1.346-3.682, P<0.001), age groups (<50 vs. >50 years old: OR=0.689, OR 95%CI: 0.561-0.847, P<0.001), areas (urban vs. suburban: OR=0.359, OR 95%CI: 0.219-0.588, P<0.001), knowledge level (high vs. low: OR=1.259: OR 95%CI: 1.188-1.335, P<0.001), and attitude (good vs. bad: OR=0.462 OR 95%CI: 0.342-0.626, P<0.001) were associated with good behaviors. The moderating effect and mediating effect shows that attitude mediates the influence of knowledge on behavior. (The 95% interval does not include the number 0(OR95% CI:0.002-0.013). All means of health propaganda can modulate the influence between knowledge and behavior (P<0.001).Conclusions: Providing adequacy of health propaganda and public health communications on the prevention of coronavirus disease makes the public fully understand the knowledge of COVID-19 and lead them to take preventive actions.
