Abstract:
The top 100 TikTok videos under the hashtag "#ttc" (trying to conceive) that featured strategies to improve the chances of becoming pregnant without treatment were assessed for medical accuracy. Videos were also characterized by creators' professional qualifications and each video's potential for profit through marketing links. Descriptive statistics and χ2 tests were used to examine relationships among these domains. More than half (57.0%) of the videos highlighted strategies that do not have a scientific evidence base. Health care professionals were less likely to promote misinformation than non-health care professionals (P<.001), but the majority of top content was created by nonprofessionals (62.0%). Non-evidence-based information was featured in 72.2% of for-profit videos. This study demonstrates high exposure and engagement with misinformation among people who are trying to become pregnant.
