Introduction Unvaccinated older adults with COVID-19 are at higher risk for severe illness and complications compared with those have been vaccinated. Vaccine literacy and attitudes are important factors that enhance healthy behaviors and choices, including vaccination intention. Objective To explore vaccine literacy, attitudes, and vaccination intention toward COVID-19 among Thai older adults and examine associations between vaccine literacy, attitudes, and vaccination intention. Methods This study used a cross-sectional online design. We surveyed 408 older adults who met our inclusion criteria. Participants were recruited online via social media and websites. The survey covered demographic data, vaccine literacy, attitudes, and intention to get the COVID-19 vaccine. Results COVID-19 vaccination intention among Thai older adults was high (81.3%). Females and those aged 60–69 years had higher COVID-19 vaccine literacy scores than males (t = −2.120, p < 0.05) and those aged ≥70 years (t = 2.438, p < 0.05). Participants with postgraduate education and those who were health professionals scored higher for vaccine literacy than less educated (t = −3.501, p < 0.01) and non-health professional (t = 5.437, p < 0.001) participants. Those with an adequate income or that had been vaccinated against COVID-19 scored significantly higher for vaccine literacy and attitudes toward the COVID-19 vaccine than participants with an inadequate income (t = 4.626, p < 0.001) or that had not been vaccinated (t = 2.842, p < 0.01). Vaccine literacy (r = 0.219, p < 0.001) and attitudes (r = 0.459, p < 0.001) were significantly associated with vaccination intention. Conclusion COVID-19 vaccine literacy and attitudes are significant factors related to vaccination intention. Health professionals could play an important role in enhancing vaccine literacy among older adults. Positive attitudes and COVID-19 vaccine literacy may enhance vaccination uptake in older adults.

Background: Foot ulceration and amputation have alarmingly increased among patients with type 2 diabetes mellitus in Vietnam. Poor foot care behavior is one of the crucial reasons which leads to diabetes related foot problems. Exploration factors related to foot care behaviors among people with diabetes becomes a necessary issue to limit this complication. Objective: To determine factors related to foot care behaviors among patients with type 2 diabetes mellitus. Methods: The descriptive correlation study was conducted in 140 participants by purposive sampling technique in the outpatient room of Da Nang Hospital, Da Nang, Vietnam from December 2017 to January 2018. Instrument used in the study included of the six cognitive impairment test, demographic form, the Nottingham assessment of functional foot care, foot care knowledge, foot care confidence scale, and foot care subscale in the social support scale for self-care in middle-aged patients with type 2 diabetes mellitus. Data were analyzed by chi-square test, Pearson product moment correlation coefficient, and Spearman rank correlation coefficient. Results: Of 140 participants, 58.6% had poor foot care behaviors. Education level, foot care knowledge, foot care self-efficacy, and social support showed a statistically significant positive correlation with foot care behaviors. There was no significant correlation between age, gender, and foot care behaviors. Conclusions: The study suggested that improving foot care knowledge, foot care behaviors and enhancing the role of nurses must be implemented for the improvement of foot care behaviors among patients with type 2 diabetes mellitus.

BACKGROUND RamaCovid is a mobile health application that provides the Thai population with information about COVID-19 and self-risk assessment. RamaCovid has a chatbot system that provides automatic conversations (available 24 hours per day) and a live chat function that allows users to directly communicate with health professionals (available 4 hours per day in the evening). OBJECTIVE This study investigated users’ utilization of and satisfaction with the RamaCovid application. METHODS Overall, 400 people were included and were recruited via RamaCovid by broadcasting an infographic about the study. Questionnaires collected demographic data, users’ experiences of RamaCovid, and the utilization of and satisfaction with the application. The questions were answered via a 5-point Likert scale. RESULTS The users had high utilization and satisfaction with the application. They used the information to take care of themselves and their family, and they gained information about their COVID-19 risk. The users were satisfied with the application because the information was easy to understand, trustworthy, and up to date. CONCLUSIONS RamaCovid provides an example of the successful implementation of an educational mobile health application. It facilitates the communication of trustworthy and up-to-date information and has enhanced people’s ability to take care of themselves and their family during the COVID-19 pandemic.

Background RamaCovid is a mobile health (mHealth) education system that provides the Thai population with information about COVID-19 and self-risk assessment. RamaCovid has a chatbot system that provides automatic conversations (available 24 hours per day) and a live chat function that allows users to directly communicate with health professionals (available 4 hours per day in the evening). The system consists of (1) COVID-19 vaccine information, (2) self-care after vaccination, (3) frequently asked questions, (4) self-risk assessment, (5) hospital finding, (6) contact number finding, and (7) live chat with a health professional. Objective This study investigates the use of and satisfaction with the RamaCovid system. Methods Overall, 400 people were recruited via RamaCovid by broadcasting an infographic about the study. Questionnaires collected demographic data, users’ experiences of RamaCovid, and the use of and satisfaction with the system. The questions were answered using a 5-point Likert scale. Descriptive statistics were used to describe the participant characteristics and their use of and satisfaction with the RamaCovid system. The Mann-Whitney U test was performed to examine the difference in use and satisfaction between the adult and older adult groups. Results The participants showed high use of and satisfaction with the RamaCovid system. They used the information to take care of themselves and their family, and they gained information about their COVID-19 risk. The users were satisfied with the system because the information was easy to understand, trustworthy, and up to date. However, the older adult group had lower use of and satisfaction with the system compared to the adult group. Conclusions RamaCovid is an example of the successful implementation of mHealth education. It was an alternative way to work with the call center during the COVID-19 pandemic and increased access to health information and health care services. Providing ongoing updated information, improving the attractiveness of the media information, and the age group difference are important issues for further system development.
