Objectives: Handwashing is known as the most preventive method for various infectious diseases. Health authorities have conducted various campaigns and public relations targeting the general population but few evaluations of these long-term interventions. This study aimed to investigate the association between experience of educational events or public relations (EXEP), attitude towards the effectiveness of handwashing (AEHW) and handwashing practice (HWP).
Setting: Using a population-based cross-sectional study with a complex sample design, we explored the response outcomes of handwashing. Those outcomes were collected biennially using Community Health Survey among the years 2013, 2015, 2017 and 2019. We applied multivariate logistic regression for the association among sociodemographic factors, health conditions, EXEP, AEHW and HWP.
Participants: Total participants residing in Seoul were 23 139 (men 44.2%), 23 004 (men 44.4%), 22 955 (men 44.8%) and 22 930 (men 43.9%), in 2013, 2015, 2017 and 2019, respectively.
Results: Overall, participants with EXEP are more likely to be women, aged between the 30s and 60s, and with a higher educational level. Particularly, participants with EXEP had an increased association with HWP (OR 1.21, 95% CI 1.19 to 1.33) and AEHW (OR 1.50, 95% CI 1.38 to 1.63). In addition, AEHW also had an increased association with HWP (OR 1.67, 95% CI 1.53 to 1.81). The mediated effect of AEHW to HWP is not determined evidently.
Conclusion: The results showed that EXEP is positively associated with HWP and AEHW among community-dwelling people. Our results confirm that educational activity can lead to more pronounced behavioural changes only when it forms a positive attitude.
