In 2021 (the latest year for which results are available)
I checked, and the results will not be available until “Spring 2023″ (exact date not given, unless I missed something), all you read was a brief preliminary report.
The CDC report assumes the “LGBQ” identifiers in the YRBS are a separate biological group,
Looking at the 2019 and 2020 reports and data, it does no such thing. It does what any good statistical analysis does, separately compares a subset which is known for occasionally confounding or skewing the data to the whole set to see if there are any significant differences. Most of the data presented is split into “boys”, “girls”, and “all”; LGBQ kids are only noted where they significantly differ from the “all”.
Note: “LGBQ” is not the OP being a jackass, or at least not just that: the CDC says that it did not collect any data on gender identities in 2021 or earlier.
10% of female high school students attempted suicide and 42% of high schoolers reported being so sad and hopeless for two weeks in a row
Did you read the part where it says that 10% of girls (and 3.8% of boys) have been raped¹, and that there has been an increase in bullying, rape, sexual assault, and violence against children in recent years? Might that have an effect, and not, say, “feminism”?
¹They don’t actually use the word “rape”, they use constructions like “physically forced into sex” because some victims go into denial mode when you ask about / refer to what happened to them using that word. It’s a form of trauma-burying, which isn’t healthy.
