The reason I'm disregarding Reddit as a significant cause is threefold:
a) Reddit is overwhelmingly male, and the most affected group are teenage girls
b) Reddit is no that big of a platform in the teenage demographic
c) Even if it were, its popularity is not in any way homogeneous across countries. If Reddit itself had an effect, the USA would be much more affected by the phenomenon than the UK, for instance.
a) Reddit is overwhelmingly male:

b) Reddit is not that big of a platform in the teenage demographic:
- Distribution of Reddit app users by age group: https://www.statista.com/statistics/1125159/reddit-us-app-us...
- Popularity of Reddit in teenagers as compared to other social media platforms: https://www.statista.com/statistics/250172/social-network-us...
