Abstract

Background

Online health information can influence consumers to make informed decisions. There are conflicting messages online about health concerns on the use of e-cigarettes. We aimed to investigate differences in those messages through Naver and Google's English versions, which are the most representative portal sites in Korea and in the world.

Methods

We reviewed the top 100 web pages related to health effects of e-cigarettes on Naver and Google in May 2018. Two medical doctors sorted the web pages into three groups as positive, negative, and mixed messages for e-cigarettes, as well as two groups based on the relative safety of conventional smoking versus e-cigarettes.

Results

There were 10 and 27 positive, 65 and 45 negative, and 25 and 28 mixed messages on Naver and Google, respectively. There were 15 messages on Naver and 53 on Google that considered e-cigarettes safer than conventional cigarettes. The most frequent topics were toxicity (71%) and diseases (22%) on Naver. Google provides topics of health concerns for young people, including gateway effect (47%), diseases (35%), and toxicity (25%). Particularly, harm reduction which was not present on Naver, came up on Google as 24%.

Conclusions

We found that Naver provides more negative messages on e-cigarettes than does Google, which means that Koreans are exposed more to negative information on e-cigarettes than are foreign people who use Google. In future, more open discussions about harm reduction should be conducted to resolve the imbalance in information regarding health effects of e-cigarettes in Korea.
