Evolution of online health-related information seeking in France from 2010 to 2017: results from nationally representative surveys (Preprint)
BACKGROUND Given the fast ongoing progression of the Internet and the increase in health information available from disparate sources, it is important to understand how these changes impact the online health information-seeking behavior of the population and the way of managing one’s health. OBJECTIVE This paper aims at describing the evolution of Internet use as a source of health information between 2010 and 2017, as well as the characteristics of online health information-seekers, the topics of interest, the sources of information, and the trust in this information and the potential impact on behavior. METHODS Data from French nationally-representative surveys Health Barometers were used (N=4,141 in 2010, 4,811 in 2014 and 6,255 in 2017.) Evolutions over time were assessed using chi-2 tests. Associations with sociodemographic characteristics and health status were evaluated using logistic regression models. RESULTS The use of the Internet as a source of health information rose between 2010 and 2014 (from 37.3% to 67.9%, P<.0001) but decreased significantly in 2017 (60.3%, P<.0001). Overall, the profile of health information-seekers compared to non-seekers did not change over time. They were more likely to be women, to be younger, to have a higher educational level, to have a higher household income and to be executives. Between 2014 and 2017, the proportion of those who did not pay attention to the source of information significantly increased to reach 39.7% (P<.0001). In 2017 as in 2014, health-related websites for general population remained the first source of information (38.6%) while institutional websites were the third (8.1%). If the credibility given to the online information is good for a large part of the information seekers since 2010 (more than 80%), it slightly decreased between 2014 and 2017 (P=.048). Above the individual characteristics, credibility was the main determinant of the way of managing one’s health (in 2017: OR=4.62; 95%CI=[3.35;6.36]). CONCLUSIONS After a rapid growth in the Internet use for seeking health information in the 2010-2014 period, a decrease was recorded in 2017 linked to a decreasing trust in the quality and reliability of information found online. These findings underlined the need for public health authorities to increase citizens’ eHealth literacy and/or to provide alternative trustworthy sources combining the popularity and accessibility of general health-information websites.
