TikTok serves as a space for health information via algorithmic curation, but raises risks like unwanted contact in 36% of young users, stranger exposure, and privacy concerns according to recent breakdowns and studies.

Les synthèses portant jusqu’à 2,8 millions d’enfants dans 64 pays montrent des associations faibles et principalement corrélationnelles entre usage élevé, apprentissages, langage et difficultés émotionnelles. Les contenus généralistes récents confirment les préoccupations sur l’image corporelle, le sommeil et l’usage problématique, mais n’ajoutent pas de preuve originale ; les modalités d’usage et le contexte restent centraux.
