Objective:

To understand the social and health behaviors associated with adolescents between 13 and 19 years old through the TikTok social network in Chile in 2021.

Methodology:

It is located in the positivist paradigm and focuses on grounded theory. 50 public videos were selected from the social platform and documentary analysis was carried out under open coding.

Results:

Adolescents place great importance on their body image, with the use of filters being highlighted in all of them, while clothing showed a trend according to gender. On the other hand, the expressions manifested are mostly positive; the sound resources used for the videos are varied, with music being the most used; the main type of content viewed is dance, followed by humor; the most frequent opinions were positive and health behaviors tended to be non-promoting.

Conclusion:

The social representations constructed by adolescents on TikTok are strongly marked by beauty stereotypes, the need for acceptance among peers, and the pursuit of popularity on social networks. Promoting health behaviors on this social network is scarce.
