Nature on social media use in adolescents with and without mental health conditions.

Not sure what’s cart and what’s horse here (maybe it’s a valuable support system…? Like how I probably would’ve died in the 1990s if it weren’t for DALnet) but either way it’s one counter indicator against my previous idea that “maybe normal people can use social media constantly and still have a great productive life”.

Study tracking mental health after bariatric surgery:

The prevalence difference in filled psychiatric drug prescription was highest 10 years after the matched index date (20·4%; 15·9–24·9), when 171 (36·5%) of 469 surgery patients and 739 (16·0%) of 4607 matched adolescents filled a psychiatric drug prescription.

TL;DR: psychiatric diagnoses & prescriptions were more common in the cohort before bariatric surgery and a lot more common after. People were feeling super bad.

The chickens & eggs get tangled up when trying to view larger trends around this issue—perhaps there are feedback loops?
