Although E-learning has been increasingly developed in recent years in various dimensions and many organizations have shown a desire to discover new methods, many organizations have not understood its advantages well. Infrastructure for increasing digital health literacy is an approach that should be considered by many organizations. To this end, this descriptive study aims to investigate the digital health literacy of primary school teachers in Sabzevar city in 2021.
In the current study, the mean and standard deviation score of E-health literacy of the teachers according to the standard questionnaire was about 25.44 ± 5.90, which is slightly lower than the standard score of 32 and is not desirable (21). In the study by Dashti et al. conducted on the level of E-health literacy of Mashhad University of Medical Sciences students, the mean score was about 28.21 with a standard deviation of 6.95, and as expected, it was higher than the value obtained in the present study. It is due to the fact that the education level and age are two effective factors in E-health literacy (22). In line with the study of Dashti et al., in this study it was also found that people with higher literacy rate and younger age have higher health literacy compared to other groups. It should be noted that due to the smaller range of education level, the age criterion had a greater effect on the level of E-health literacy, so that the level of health literacy in the age group of 20–30 years (28.23 ± 5.41) had a smaller difference compared to the value obtained in the study of Dashti et al. This finding can be attributed to the higher level of access of this group to virtual space. In further comparison with previous studies, it was found that in studies on university student groups, compared to the teachers studied in the present study, the level of health literacy obtained higher scores in both standard and complete questionnaires. In the study by Haerian et al., the mean score of E-health literacy of students was 76.88, and in the study of Mahmoudi et al., based on the standard questionnaire, the level of health literacy was average (23).
The evaluations in this study showed that increasing the education level, especially at relatively young ages, improved people's health literacy due to the greater access of these groups to the Internet.
The amount of using the Internet and the type of tool used to connect to the Internet are other factors affecting the level of E-health literacy. Therefore, people who connect to the Internet daily and with the help of more convenient tools, such as smartphones or tablets had a higher level of health literacy. It is due to the fact that since people with tablets and the most hours of Internet use have the highest health literacy score compared to other groups. These findings are consistent with the study by Isazadeh et al., in which they examined the E-health literacy of patients referring to a military hospital. It was pointed out that the amount of Internet use improved health literacy (24), due to getting more information through social networks and websites. Considering that using social networks through smartphones is much easier than home and office computers, the level of health literacy improvement is higher in the groups owning tablets and smartphones.
The gender of the teachers had an insignificant effect on the findings of this study, so that in the standard questionnaire, males scored slightly higher and in the complete questionnaire, males scored relatively higher. This result is not in line with the studies of Isazadeh et al. and Richtering et al. (24, 25). However, it was in good agreement with the study of Norman et al. in 2006. In the study of Norman et al., males had higher E-health literacy (26). This result could be due to to the higher access of males to electronic tools.
The results also revealed that according to the standard questionnaire, the mean score of E-health literacy score of people with diseases and a history of drug use was higher than healthy people. This finding is in contrast with the findings reported in the studies of Haerian et al. regarding oral and dental health, Raeisi et al., and Wolf et al. (22, 27, 28).
According to the results, it can be concluded that having dietary regimens and regular exercise as well as having general knowledge led to higher scores among the teachers. This study shows the mutual influence of health literacy and health behavior of people (29, 30).
The studied teachers mentioned that they have the ability to evaluate and recognize the correctness of health-related information and use them in their daily lives. This finding shows that they have the ability to identify accurate and quality sources that have had positive results in their lives. This result is not consistent with the study of Rasouli et al., in which they stated that the people referring to Tehran military hospitals did not have the ability to identify accurate health-related sources and as a result, did not trust the information available on the Internet (24). This difference can be due to the amount of false information available on the internet and also the low level of education in the group of military patients compared to teachers. This finding shows that the education level not only increases health literacy, but also affects the finding of accurate and reliable sources.
One of the limitations of this study is using self-measurement and in some cases, it is possible that the responses do not reflect real health literacy. Another limitation is the lack of functional, critical, and interactive dimensions in the E-health literacy measure, leading to differences with other similar studies. Moreover, some teachers did not participate in the study due to various reasons, such as cultural and family, and environmental conditions.
